Agricultural Insurance – an Effective Control Mechanism for Non-performing Assets of District Central Co-operative Banks in India

AGRICULTURE INSURANCE – AN EFFECTIVE CONTROL MECHANISM FOR NON-PERFORMING ASSETS IN DISTRICT CENTRAL CO-OPERATIVE BANKS OF INDIA

All the agriculture plans projects and schemes are subjected to yield risks. As these are highly dependable to weather, monsoon, rainfall and other natural calamities the amount of risk is unpredictable. In India most of the agriculturists don’t have the awareness about the agricultural insurance plans and schemes provided by the Government in mitigating losses arising out of agriculture. If there is any loss due to natural calamities they demand only the writing off the agriculture credit availed. They don’t avail the mitigating mechanisms, which are readily available to protect them from unexpected losses. This article provides a basic knowledge about the available insurance facility to mitigate the risk in agriculture.

RISKS IN AGRICULTURE:

Five general types of risk are identified. They are:

1.Production risk – derives from the uncertain natural growth processes of crops and livestock.

2.Price or market risk – refers to uncertainty about the prices that will be received for commodities.

3.Finanacial risk – rising interest rates, the prospect of loans being called by lenders, and restricted credit availability are also aspects of financial risk.

4.Institutional risk – due to uncertainties accumulated by government actions.

5.Human or personal risk – refers to factors such as problems with human health or personal relationships that can affect the farm business.

Among agricultural insurance products, crop is considered as the most important category. Other types include cattle, poultry, equipments used for agriculture etc.

INSURABILITY UNDER AGRICULTURAL INSURANCE:

The agricultural insurance policy prescribes certain conditions regarding the insurability under the policy. These include:

1.The risks should cause economic loss to the farmer covered under the policy.

2.The loss can be expressed specifically in monetary terms.

3.The risk of loss in the future can be estimated by analyzing the past data’s.

4.The loss must not be minor or negligible.

5.The insured farmer should have the financial capacity to pay the premium amount or should be eligible for government assistance.

TYPES OF CROP INSURANCE SCHEME:

The various types of risks, which are covered under the policy, include loss of the crops due to:

Natural fire and lightning, Storm, hailstorm, cyclone, typhoon etc, Flood, inundation and landslide, Drought, dry spells, Pests/ Diseases etc.

CATEGORIES OF FARMERS COVERED UNDER THE SCHEME:

The category of farmers who are covered under the policy includes:

1.All farmers growing notified crops and availing seasonal agricultural loans from financial institutions are covered on a compulsory basis. This category is referred to as loanee farmers.

2. All other farmers growing notified crops who opt for the scheme are covered on a voluntary basis.

Sum Insured:

Farmers are also allowed to insure their crop beyond the value of the yield level.

LEVELS OF INDEMNITY:

The indemnity under the scheme varies based on the nature of risks. The scheme identifies three types of risks viz., low risk, medium risk and high risk. If the yield variation is 14 percent or less, it is considered as low risk. If the yield variation is between 16 to 30 percent, it is termed as high risk. Three levels of indemnity are available viz, 90%, 80%, and 60% for low risks.

CLAIMS SETTLEMENT UNDER CROP INSURANCE:

The claims arising out of losses under the national crop insurance schemes are shared by the implementing agency (Agriculture Insurance Corporation Of India) and the government proportionately. This sharing is done for a period of five years till the actuarial rates get implemented. In case of food crops and oilseeds, any claims beyond 100% of premium will be borne by the government. All normal claims, i.e., claims up to 150% of premium will be met by implementing.

SUM INSURED

Farmers are also allowed to insure their crop beyond the value of the yield level.

LEVELS OF INDEMNITY

The indemnity under the scheme varies based on the nature of risks viz, low risk, medium risk and high risk. If the yield variation is 14 percent or less, it is considered as low risk. If the yield variation is between 16 to 30 percent, it is termed as medium risk and above 30 percent is termed as high risk. Three levels of indemnity are available viz, 90%, 80%, and 60% for low risks.

CLAIMS SETTLEMENT UNDER CROP INSURANCE:

The claims arising out of losses under the national crop insurance scheme are shared by the implementing agency (Agriculture Insurance Corporation Of India) and the government proportionately. This sharing is done for a period of five years till the actuarial rates get implemented. In case of food crops and oilseeds, any claims beyond 100% of premium will be borne by the government. All normal claims, i.e. claims up to 150 % of premium will be met by implementing agency and claims beyond 150% shall be paid out of corpus for a period of three years. After this period of three years, claims up to 200% will be met by the implementing agency and any claims above this will be met out of corpus fund.

Implementing agency makes the settlement of claims in the case of normal losses for annual commercial or horticultural crops. This includes the claims up to 150% of premium in the first three years and 200% of premium there after subject to satisfactory claims experience. The claims beyond 150% of premium in the first three years and 200% of premium there after shall be paid out of corpus fund for a period of three years. After this period of three years, claims up to 200% will be met by the implementing agency and any claims above this will be met by out of corpus fund. Implementing agency makes the settlement of claims in the case of normal losses for annual commercial or horticultural crops. This includes the claims up to 150% of premium in the first three years and 200% of premium there after subject to satisfactory claims experience. The claims beyond 150% of premium in the first three years and 200% of premium thereafter shall be paid out of corpus fund. However, the period of three years mentioned for this purpose will be reviewed on the basis of financial results after the first year of implementation. The period will be extended to five years in case of necessity.

PILOT CROP INSURANCE SCHEMES

The first pilot crop insurance scheme was introduced in the year 1978-79. This scheme functioned till 1985 when the comprehensive crop insurance scheme was formulated. The nine states where the pilot schemes were implemented were Andhra Pradesh, Tamil Nadu, Madhya Pradesh, Bihar, Maharashtra, Assam, Karnataka and Rajasthan.

NATIONAL AGRICULTURAL INSURANCE SCHEME (NAIS)

(RASHTRIYA KRISHI BIMA YOJANA-RKBY)

The Objectives Of the Scheme:

Ø Provide insurance coverage and financial support to the farmers in the event of the failure of any of the notified crop as a result of natural calamities, pests & diseases.

Ø Encourage the farmers to adopt progressive farming practices, high value inputs and higher technology in Agriculture.

Ø Help stabilize farm incomes, particularly in disaster years.

RISKS COVERED

Under the scheme, comprehensive risk insurance is provided to cover yield losses due to non-preventable risks, viz.

a. Natural Fire and Lightning

b. Storm, Hailstorm, Cyclone, Typhoon, Tempest, Hurricane, Tornado etc.

c. Flood, Inundation and Landslide.

d. Pests/Diseases etc.

PREMIUM SUBSIDY

A 50% subsidy in premium is allowed for Small and Marginal farmers, which is shared equally by the Central Government and State or Union Territory Government.

PILOT SCHEME ON SEED CROP INSURANCE (PSSCI)

Objectives of the scheme:

Ø To provide financial security and income stability to the seed Growers in the event of failure of seed crop.

Ø To build confidence in the existing seed growers and stimulate participation of new growers to undertake seed production program of newly released hybrid/ improved varieties.

Ø To provide stability to the infrastructure established by the State owned Seed Corporations/ State Farms.

Ø To give a boost to the Modern Seed Industry to bring it under Scientific Principles.

The Compensation payable is on the basis of the graded scales are as follows:

Ø Failure of seed crop within one and half months of sowing and until the crop is harvested, the compensation will be 80% of the sum insured corresponding to the rejected area.

Ø Failure of seed crop after one and half month of sowing and until the crop is harvested, the compensation will be 80% of the sum insured corresponding to the rejected area.

Damages to the harvested seed crop due to operation of the above- mentioned perils while lying on the field but before removal from the field for transportation to the processing plant are covered under the scheme.

FARM INCOME INSURANCE SCHEME:

The objectives of the scheme are as follows:

Ø To provide financial support to farmers, in the event of loss in income from adverse incidence of Crop Yield (On account of natural calamities, pests and diseases) and Market Price fluctuations.

Ø To encourage the farmers to adopt prudent and progressive farming practices, both in terms of agricultural technology, and market economics.

Ø To enhance food and livelihood security of the farming community.

Ø To help stabilize farm incomes, particularly in diseaster years.

Sum Insured

The Sum insured is computed on the basis of Guaranteed Income per hectare:

Guaranteed Income (per hectare) = Average Yield of past 7 years * Indemnity Level * Minimum Support Price (MSP) or current year.

Premium Subsidy

Ø Small/ Marginal farmers: 75% of Premium

Ø Other farmers: 50% of Premium

RURAL INSURANCE SCHEMES: CATTLE INSURANCE

COVERAGE:

The insurance scheme is offered to protect owners of animals mentioned above from any natural hazards and to provide compensation to the owners of the animal when loss occurs. The insurance cover can be obtained by regularly paying small amounts called premium to the insurance company. Thus by taking a cattle insurance policy big losses befalling the few cattle owners are shared by the insurance company thereby protecting the owner.

SUM INSURED:

The sum insured depends upon the type of animal and breed such as cow, buffalo, local breed, pure breed or crossbreed. The sum also depends on the age, sex and health of animal.

POULTRY INSURANCE POLICY

Poultry means domesticated species of birds reared for eggs, meat or feathers and includes chicken, ducks, geese, turkey, etc. The poultry insurance policy provides indemnity against death of birds due to accident or diseases. The policy covers death due to fire, lightning, flood cyclone, earthquake, etc. The term poultry includes layers, broilers and parent stock.

PERSONAL ACCIDENT INSURANCE SOCIAL SECURITY SCHEME FOR POOR FAMILIES:

The scheme was introduced by the central government with a vision of rehabilitating poor families affected by death of its earning member who is not covered for compensation under any insurance scheme or any law/statute. The scheme was operated through GIC and its subsidiaries in co-ordination with the respective state governments. Now the public sector companies and state governments are handling the scheme. Initially it is introduced only in certain select districts.

SERICULTURE INSURANCE (MULBERRY SILKWORM CROP INSURANCE)

The scheme is applicable to univoltine/bivoltine/pure or hybrid races of mulberry silkworm crops. The scheme covers the worm from egg stage to cocoon i.e., from the time the eggs are purchased by the farmers till the cocoons are harvested.

MARKET AGREEMENT ON AQUACULTURE (SHRIMP) INSURANCE SCHEME

The Scheme is applicable to duly licensed arms or farms in accordance with the government notification growing brackish water shrimp/fresh water prawns by adopting extensive/modified extensive/semi-intensive system only.

HONEY BEE INSURANCE

The honeybee insurance covers beehives and/or colony belonging to cooperative societies. Bee colonies of Indian honeybee and Italian honeybee only shall be covered under the scheme. It covers accidental loss or damage to be hives and / or colony including terrorism. Paying an additional premium can also cover theft risk. The policy can be availed by co-operative societies, banks (for their members), loaners, units etc. The scheme provides both basic cover and additional cover. The Honeybee Insurance Policy will pay 80% of the claim amount by considering the total cost.

RABBIT INSURANCE

The insurance scheme is available for rabbits, which are aged between 3 months and 3 years. The premium is payable at 7% of the sum insured per annum.

ELEPHANT INSURANCE

Elephants are categorized in to temple elephant and others. Temple elephants include those aged between 5 and 60 years. The premium under this category is charged at 4.50% of the sum insured. The other category includes those aged between 5 and 60 years and above 60 and up to 65 yrs. The premium per annum is 5.00% and an additional premium of 0.5% is charged for each additional year.

SHEEP AND GOAT INSURANCE

The sheep and goat insurance policy coverage and other procedures are almost the same as that of the cattle policy. The sum insured and the indemnity amounts are same as the cattle insurance policy.

PIG INSURANCE

Poor people usually do pig rearing and thus the insurance policy assumes significance. In India, Uttar Pradesh is at the foremost position in the production of pork. The insurance coverage is available for those people who buy pigs under the IRDP schemes.

CAMEL INSURANCE

Insurance of camels assumes significance in places where they are used for different types of draught work. Camels are used for transportation purposes in hot, arid and sandy regions. One fourth of the world’s camel population is in India and thus the policy has significance in the country. The policy excludes all the common risks mentioned in the cattle insurance policy.

AGRICULTURAL PUMP SET INSURANCE

Agricultural pump set insurance policy is applicable to centrifugal pump sets and submersible pump sets. The maximum capacity of the pump set that is covered under the policy is 25 H.P. The policy gives cover only for those sets which are used for agricultural purposes and are made by approved manufacturers.

INDIAN AGRICULTURISTS POINT OF VIEW

1. The premium payable is not refundable. So they feel that it is a waste of money.

2. The government agencies do not educate them properly.

3. They feel that this is for the benefit of the government and the Insurance Companies only.

4. They feel that the premium payable is not affordable.

5. They feel that it is the responsibility of the government to clear off their losses.

6. They believe that the government will and should take up the responsibility every year.

7. They believe that the agricultural losses are impossible to mitigate.

So most of the borrowers of agricultural credit do not have the habit of repayment. It accumulates the overdue and ends in non-performing assets for the District Central Co-operative Banks (DCCBs) in India. In order to save the DCCBs the government agencies should come forward to educate the needs and uses of available agricultural insurance plans and schemes to mitigate their risks. All such facilities must me simplified and the premiums must be made affordable for the poor farmers. This will definitely reduce or share the risk of losses to both government and the poor agriculturists in India. “IT WILL BE AN EFFECTIVE MECHANISM TO CONTROL THE NON-PERFORMING ASSETS OF DCCSs IN INDIA”.

Introduction:

 

       Wild animal-human conflicts have started since beginning of human era from Adam and Eve. This conflict of wilderness made man to hide in caves and he was called as “Cave man”. Slowly, with his advancement it is he who invented Axe and other weapon in stone and iron ages to frighten the wild animals, initially. Later on he hunted them to save himself. This feeling of uncertainty and fear of wild animals and wilderness reduced with the invention of fire. He made sharp weapons of bones and iron. These initial weapons were the beginning of this conflict, Animal human conflict.

Thirty thousand years ago, the human population rose to 6 million. They were still hunters. With the invention of fire, he set fire a vast majority of sanctuaries, which scared wild life and they migrated from his neighborhood. Many forests, hills and difficult terrains were still beyond the reach of man three thousand years before, although human population has increased to 60 million. Man has already started primitive agriculture. He had made his terrains and wild life scared by him left his close habitats and searched for fresh abodes. Man by now had lust for fur, horns, ornaments and other forest resources. He invented many means to frighten whole wild life. He became a “Danger “not only for wild animals but for his own species, environment and eco-biodiversity.

Three hundred years ago he industrialized crop production and produced enough food, for nearly 600 million people. This continued and from 30 year now he is feeding 6000 million people. Today we have a global food security for 7.5 billion. Human food security gains resulted in reduction of all other wild species, thus, the origin of wild- life- human conflict is the lust of man for more food, more luxury or sometimes fun for hunting or fur. This reduced wild life reserves and now a open conflict came into existence.

Many man-wild life conflicts have been reported from Gir forests of Gujarat, Rajaji National Park in UP and many other states where forest lands became cultivable lands. Elephants, wild boars, monkeys, squirrels, deer , birds like crows, parakeets, wild dogs, jackals, gaur, sambur, langure, fowls, pea cocks, neilgai, Hippos, biats, blackbirds, rodents, wild pigs, feral species, primates, beetles, foxes, pigeons, feral hogs and a variety of other species damage crops. The carnivores even attack human too. These attacks are for search of food or their loss of habitat. Many such accidents came to be known in Jammu and Kashmir. The bear leopod and other wild animals are reducing in number. Their habitats used by human.

The human causalities are due to carnivorous species, but herbivores inflict economic and human losses too. The crop damages by wild life has been the new threat to agricultural productivity throughout the world. This also concerns us in Asia and India. This review is aimed to find out:

1.       Extent of damage to crops.

2.       Nature of crop damage

3.       Ways and means to prevent these losses.

4.       A strategic planning to drive a line between wildlife conservation and farm economics especially in India.

 

Executive Abstracts and Strategic elementaries: [EASE]

1.     Importance

                   Species causing crop damages ranges from elephant’s wild birds, monkeys, squirrels, deer, parakeet, wild dogs, foxes, deer and many others like Neilgai. On an average this damage to crops by wild animals amounts to U$ 961 per hectare. It is much more than an Indian Farmer earns from a hacter annually. Therefore, by these estimates, the damages are spectacular and economically important.

2.       Human Elephant conflicts (HEC):

          i) Economic Losses:

                   Among elephants crop raiding is common. The crops near their home ranges are damaged more. Elephants damaging crops had twice big ranges than those who did not damage the crops. Thus, more proximity of the crops near their ranges are prone to crops damages. Train accidents instigate elephants more to crop or human damages. Indonesia saw more frequent raids of elephants on crops. Human elephant conflict (HEC) is frequent and poses serious challenges in Africa. Both male groups and family group attacks have been observed. HEC losses in West Bengal were worth 3.2 croses of Rupees. This damage occurred in 3368sq kms.radius. The numerical number of elephants was 62 only. Assam observes damages to the woodcutters by elephants Asian wild Elephants raid and damage crops in herds of 10-13 individuals or big herds comprising 50-74 elephants. In Darjeeling district alone over an area of 200 kms. East to west, in last two decades 277 houses were demolished by elephants, killing 66 people in 5 districts. As a result of this conflict 23 elephants lost their lives. In 2001, economic loss of the order of US fifty thousand dollars was estimated to be inflicted by elephants. This scenario necessitates comprehensive measures to be taken to lessen these damage. The review of the measures, around the world suggest following few studies to be undertaken and resultant measures to be applied to lessen these damages.

ii)     Mitigation of losses:

          Methods developed and used to mitigate crop damages by elephants consisted of frightening of animals by drum beating, firegracks or even air gun fires. Guarding the crops by fences or even using electric fencing or raising poles and wiring may be effective. Chemical based deterrents, and electric fencing have been found to reduce crop damages. High voltage electric fencing using energizers in west have prevented wild animals damaging crop but this preposition may not be applicable in areas where even habitations do not have access to electricity. However, this method may act as a temporary boundary separating wild and domestic habitats. This could prevent intrusions from sly vatic to domestic foci. Guarding fields, digging trenches, modifying cropping patterns have a possibility of reducing man elephant conflicts or Human elephant conflicts. A 30% open space between two habitats may help to avoid HEC. This means a distance to be maintained between cropping fields and elephant habitates. A proper investigation on these lines is needed. A grid based geographical information system (GIS) with a 25Km2 resolution may help to have cost effective data source to analyze these situations. There is urgent need of identifying spatial predictors of HEC. On the basis of this study one can suggest or plan mitigation strategies, early warnings of attacks, use of barriers and deterrents. The utility of the methods could be assessed for land use and livelihood strategies to limit HEC.

 

3.       Dear-Nilgai Damages.

          A survey of 2500 farms in UK revealed that 69% (n=192) cereal crops were damaged by deer. This damage costed £500 per annum per farm. Damages varied with deer density. In USA too deer damages comprised of crop loss, landscape damages, car accidents and property damages. Nilgai damages alongwith deer damages are common in India too. Tree cover of Acacia in the area is generally used as shelter by Nilgai. We have encountered huge crop damage in Mathura (CIRG) and nearby area by Nilgai visits. Grazing and browsing of Nilgai inflict losses on farms. This is regarded as a mammalian crop threat by the farmers. This behaviour of their inflict ozone injury to the young sapling, so precious for the growth of trees in Indian semi-arid farms.

 

          Corn damages by deer in USA amounts to 6.6.% per hectare. In an area where a farmer owned 125 hectare on an average 55 hectares were used to sow corn. There is a 6.6% loss of the product which is a huge economic loss. Similar damages by deer in Ontario, Canada, Portugal, Japan, South America and other parts of the world have been reviewed. In Virginia too a study involving 1506 agricultural producer farmers revealed 58% of them experiencing deer damages. Ways and means to prevent such attacks on crops have been reviewed. Most of the possible measures to be adopted are similar to these described for elephants (HEC).

 

4.    Other Mammal and bird damages

 

          Monkey damages maize, sweet potato and other crops. It is suggested to reduce or change cropping pattern or alternating with non-agricultural activities near location of monkey habitats. Various methods are reviewed. Bat damage, Hygo crop damages in Japan, Grape wine damages by bats in Andra Pradesh, India have been studied. Crop economic loss assessment has been reviewed in these pages. Clover rather than grass can reduce wild mammal damages. Alley cropping of black walnuts helped to save soyabean and maize crop damages. Pesticide damages wildlife and minimize their attacks, enclosures and other electric fencing help to avoid such damage. Can one use harmful means to save crops, need a suitable strategy to preserve ecology and biodiversity. Both crops and wild animals need security and conservation. A management strategy is needed to safeguard human and wildlife equally.  A policy framework is envisaged.

 

          Blackbird crop damage in USA amounts to 5-8 million dollars. A considerable sum of crores of rupees have been estimated to be damages in the form of crop, human and property losses by wild animals, birds and other rodents in India. Many measures to reduce these losses are needed and have been reviewed.

 

 

 

 

 

Review

1. Wild animals damaging crops

To elephants wild boar, porcupine, rheus macaque (Macaca mulatta), hoary-bellied squirrel, barking deer (Muntiacus muntjak), red-breasted parakeet (Psittacula alexandri), and wild dog are wild animals damaging crops.

Methods developed and being used to mitigate man-wildlife conflict include, frightening the animals; guarding the crops; and using some sort of scarecrow and traps (Miah et al 2001).

Accurate estimation of crop damage by wildlife (raccoons, white-tailed deer, and coyotes) often requires labour-intensive sampling procedure. Variable area transect (VAT) sampling has been identified as a potential labour-saving alternative to quadrat sampling ( Engerman et al 2002).

 

2. Wild life Human conflicts

Agricultural landowners suffer in the form of damage to crops, livestock, and other property. Some wildlife agencies maintained abatement and compensation programmes. A model of deer-inflicted crop damage used to facilitate agency decisions regarding deer densities and distribution, abatement use, and to forecast compensation. The model is applied to field-level compensation claims in Wisconsin, USA. The results are consistent with theory, ( Yoder J, 2002).

 

3.  Crop Economic loss due to wild life

          People’s perceptions were discerned through participatory discussions covering 419 households distributed in 10 villages in the buffer zone. Traditional uncodified rights of local people were substantially reduced through policy interventions set in since 1860s. Local people as well as tourists have been excluded from the core zone covering an area of 625 km2 since 1982. Deterioration of rural economy due to damage to crop and livestock by wildlife and, termination of opportunities of income from wild medicinal plant resources and tourism in the core zone were the key negative impacts of conservation policy felt by more than 90% of respondents. Mean annual economic loss per household was estimated as Rs.1285, Rs. 1195 and Rs.156 due to damage caused by wildlife to food crops, fruit trees and beehives, respectively, Rs. 1587  due to ban on collection of wild medicinal plants for marketing and Rs.7904 due to ban on tourism in the core zone. The Reserve authority granted compensation for livestock killed by wildlife but it was hardly 5% of the market value of killed livestock as assessed by the people. People did not appreciate much the present benefits from the reserve management in the form of wages for carrying out afforestation work, partial compensation for livestock depredation and availability of solar power devices, wool, and spinning devices. Approximately 95% respondents identified empowerment of local people in respect of realizing income from timber from dead/diseased trees in community forests, income from medicinal plants in buffer zone and opening of the core zone for tourism as potential development options. Improvement in rural economy, the prime concern of local people, has not received as much attention as legal enforcement of protection by the reserve management. There is a need for developing policies and management actions that serve the economic interests of local people together with enhancement of environment conservation goal (Maikhuri et al 2001).

 

4.  Crop selection:

Damage was less (34%) in experimental carrot as multiple crop than  carrots as only crop planted (62% damage). Staggered plantings of canola, which continuously produced flowers, was the most effective lure crop of the green manure crops we tested. Carrot producers should use electric fences or 2.4-m woven wire fences, perhaps combined with staggered canola plantings, to reduce carrot depredations ( Schwab et al 2001).

          The colver, rather than fertilized grass, is more effective cover crop on AFAs, against damage by migratory geese. The sward should be managed to encourage clover growth, which would probably involve frequent cutting but no fertilizer. Further research is needed on clover replenishment rate over the winter season and possible benefits of clover leys to other wild life (McKay et al 2001). Alley cropping of black walnuts and percent with maize and soyabean rotations may avoid will animal damages. Tree –crop ratio of 1:10 may help( Godsey, 2000).

 

5.  Elephan- human conflicts:

Conflicts between elephants (Elephas maximus) and human occur in Rajaji National Park (RNP), Uttar Pradesh, one of eleven reserves designated in India, to conserve Asian elephants. Elephant-human. The conflicts in RNP from 1996 to 1999 were studied, and all human and elephant deaths or injuries caused by conflict were recorded. The impact of human colonies on elephant movement was studied in 18 villages along 17 km of the sourthern boundary of the study site and 4 village in the Chilla-Motichur corridor. Three male and four female elephants were radio tracked for 1-2 years. Primary conflicts included crop raiding, competition between humans and elephants for vegetation, and elephant mortality due to train accidents. Adult males that raided crops had home ranges twice as large as adult males that did not raid crops. Elephants only damaged crop of fields that occurred within their home ranges. Field trails of chemical based deterrents and electric fencing should be tried to reduce crop damage. Train speeds need to be reduced to prevent accidental elephant mortality (Williams et al 2001).

 

Wild Elephant damages:

          A rapid village and field assessments, data survey showed. Elephants raided crops at a rate of 0.53 elephants per day in Indonesia. The frequency of crop raiding was related to vegetation type along the park border, the size and presence of rivers, and the distance to the park’s Elephant Training Centre (ETC), which houses about 150 captive elephants. Wild elephants damaged at least 450000  m2 of maize, rice, cassava, beans and other annual crops, and close to 900 coconut, banana and other perennial trees in the area surveyed. Elephants killed or injured 24 .Villagers try to reduce elephant damage by guarding fields, digging trenches between the park and their fields, and modifying their cropping patterns. Elephants-human conflict decreases the probability of support from local people for conservation efforts. The approaches are suggested consist of elephant trenches, electric fences, external support to affected villages, and compensation to villagers for any damage caused (Nyhus et al 2000).

          This study explores land use conflict in south east Kajiado District, Kenya. The results of household surveys conducted with farmers and herders in 1977 and 1996 to examine changes in land management strategies are compared. The conflict reflects ongoing competition over access to scarce land and water resources between herding, farming and wildlife are the reason of damage of crops. This man-animal conflict needs understanding the conditions that have created the present conflicts (Compbell et al 2000).

It is, therefore, suggested that 30% open space be used as a basic division for stratifying thickets into low –use and high-use categories for deer density estimation. The proportions of each type could be derived from grid-square measurements of aerial photographs (Latham J 2000).

 

 

Human elephant conflict

          Human-elephant conflict (HEC) in Africa occurs wherever these two species coincide, and poses serious challenges to wild life managers, local communities and elephants alike. Mitigation requires a details understanding of underlying patterns and processes. Although temporal patterns of HEC are relatively predictable, spatial variation has shown few universal trends, making it difficult to predict where conflict will take place. Crop raiding was further subdivided into incidents involving only male elephants or family groups. A relatively fine-resolution, systematic, grid –based method was used to assign the locations of conflict incidents, and spatial relations with underlying variables were explored using correlation analysis and logistic regression. Crop raiding was clustered into distinct conflict zones. Both occurrence and intensity could be predicted on the basis of the area under cultivation and, for male elephant groups, proximity to major settlement. Conversely, incidents human injury and death were less predictable but were correlated with proximity to roads. A grid-based geographical information system (GIS) with a 25km2 resolution utilizing cost-effective data source, combined with simple statistical  tools, was capable of identifying spatial predictors of HEC, At finer resolutions spatial autocorrelation compromised the analyses. Synthesis and application. These results suggest that spatial correlates of HEC can be identified, regardless of the sex of the elephants involved. Moreover, the method described here is fully transferable to other sites for comparative analysis of HEC. Using these results to map vulnerability will enable the development and deployment of appropriate conflict mitigation strategies, such as guarding, early warning systems, barriers and deterrents. The utility of such methods and their strategic deployment should be assessed alongside alternative land-use and livelihood strategies that limit cultivation within the elephant range (Sitati et al 2003).

          Human elephant conflicts (HEC) in west Bengal was an economic loss worth 3.2 crores. This much damage occurred in 3368 sq km radius inhibiting 62 elephants (Singh et al 2002)

 

6.   Kerala Survey

Crop damage by wild animals in Kerala, India, was studied from 1993 to 1996. Data were collected from the offices of the Kerala Forest Department, field survey and from the intensive study area at Marayur, Idukki District. Forty-five species of crops were destroyed by wild animals in Kerala, the species commonly destroyed by wild animals were paddy, coconut plam , plantains , cassava , arecanut, coffee, oil plam , pepper , jack tree, mulberry and manago. The main animals involved in crop damage were elephant (Elephas maximus), gaur (Bos gaurus),sambar (Cervus unicolor), wild boar (Sus scrofa), bonnet macaque (Macaca radiate), common langur (Presbytis entellus), blacknaped hare (Lepus nigricollis) and pea fowl (Pavo cristatus). Among these, elephants and  wild board gave maximum damage . Of the total compensation claimed by the farmers, only 8.2% was sanctioned by the Kerala Forest Department. The highest crop damage (30%) was recorded from the forest ranges coming under the Northern Circle: pinapple (47%) , sweet potato (47%), tapioca (42%), alocasia (39%) , beans (25%) and plantains (23%) recorded highest percentage of damage. In the intensive study area at Marayur, 28 species of crops were damaged and highest damage was during the summer months. At maximum damage was due to elephant (72%) followed by gaur (62%) , sambar (17%) and wild boar (16%) . Tiger (Panthera tigris), panther (leopard) (Panthera pardus) and wild dog (Conine alpinus) were the main cattle lifters in the state. A total of 31 deaths and 64 injuries caused by wild animals were recorded from the state during the period 1983 to 1993. Thirteen indigenous methods used for controlling the crop damage had been identified. High voltage electric fencing using energizer was effective for stopping elephants and other herbivores from entering the agriculture fields. Crop damage is found to be linked to the cropping pattern and location of the agriculture fields. Short term and long-term measures needed to prevent the crop damage are discussed (Jayson  EA,1999).

 

7.  Bird crop damages

 

Use of non-lethal method to avoid crop damages by bird have been reported. Blueberry damages by cedar waxwings (Bombycilla cedrotun were minimized. (Avery et al 2002).

 

8. Wild Bird damage

 

          In the northern Great Plains of USA,  conflicts between red-winged black birds (Agelaius phoeniceus) and sunflower (Helianthus annus)  growers have intensified since the late 1960s due  to the expanded  commercial production of sunflowers. We studied the potential population effects of the removal of up to 2 million red-winged blackbirds annually under a 5 year programme of baiting during spring with DRC-1339 (3-choloro-4 methalalanine) treated rice. They also examined whether lethal control, in combination with current levels of breeding habitat management, would be cost effective in decreasing depredation of sunflower crops during  late summer. They evaluated the cost benefit ration for 4 culling scenarios involving (1) variable annual cullus, not exceeding 2 million birds, with and without density compensation (i.e. ,a positive density-dependent response) on adult survival and (2) culls of 2 million birds annually with and without density compensation .We constructed a red –winged blackbird population model  represented as an age-based matrix and calibrated to stable growth. We assumed a total population of 27 million birds on 1 April (week 1), representing the red-winged blackbird breeding population staging in eastern Southern Dakota and migrating into North Dakota.Under each culling scenario, we reduced the stable red-winged blackbird population (Equally for females and males) and project the population through week 23 of the annual cycle (2 Sep). We then evaluated the associated costs of the management relative to potential sunflower crop losses, assuming $0.07 in damage per bird and  4% loss to other factors. Variable annual culls, likely the more biologically realistic model scenarios, yielded mean annual removals of 1 240 560 (SE=12 328) birds with density compensation and 1 231 620 (SE=28 811) birds without density compensation,, with cost benefit ratios of 1:2.3 and 1:3.6, respectively. Annual intrinsic rates for the model population over  the 5 year period ranged from 1-4 to 4.8%. Considering potential variability in the effectiveness of the cull and  the combination of direct and indirect costs,we contend  that the realized benefits to sunflower growers by lethal control of red-winged blackbiards via spring baiting , in combination with current nonlethal management efforts, would likely be negligible (Blackwell et al 2003).

          The efficacy of hydrolyzed casein (HC) and retail products that contain HC in reducing deer damage to trees and shrubs was determined in a field experiments conducted in USA during 2004-05. The results of the experiments indicate the suitability of HC as a deer repellent. Technical grade HC completely eliminated browsing damage to evergreen shrubs (Gaultheria shallon) and conifers (Thuja plicata). Retail sources of HC were not as effective as the pure hydrolyzed protein (Kimball et al 2005).

 

 

9. Blackbird damages

          The economic impact of blackbirds can be severe to rice producers in the United States. One approach to managing this damage is the application of bird-deterrent chemical to the crop. Previous pilot trials suggested that caffeine offered potential as a safe, economical bird repellent. In this study, cage feeding trials  with female red –winged blackbirds and male brown headed cowbirds confirmed that a treatment rate of 25000 ppm caffeine on rice seed reduced consumption as much as 76% . Trials with mixed species blackbirds flocks in  a 0.2-ha flight pen resulted in just 4% loss of caffine-treated rice compared to 43% loss of untreated rice. . Field trials of a 10 000 ppm caffeine treatment in Louisiana revealed > 90% of caffeine-treated rice seed remained unconsumed on days 2 and 3 of the study whereas blackbirds consumed > 80% of the untreated seed. As a rice seed treatment to deter blackbirds, caffeine appears to be effective, economical and environmentally safe, although additional aquatic toxicity testing is desirable. Improvements in formulation will be needed to make the compound practical for general agricultural spray applications and to extend the adherence of caffeine to rice seeds in field conditions ((Avery et al 2005).

 

10. Deer damage

A questionnaire was distributed to over 2500 farms to know damage  caused by lowland deer to crops, trees and vegetation. Results from the questionnaire showed that 69% (n=1192) of responding farmers had deer on their holdings and that Roe and Fallow were the most frequently seen species. On those farms with deer present, cereals were the most commonly damaged crop (44%), but only 15% of these farmers claimed that the annual cost of damage to cereals exceeded £500 each year for the whole farm. Validation assessments were based on two visits to assess deer damage to the crop, with a deer species/density assessment during the March assessment and an assessment of grain yield and quality during the August assessment. Respondents were generally accurate in the density and species of deer reported. The percentage of the farm suffering damage attributable to deer was very variable, generally being higher at the first assessment than the second. The figures calculated for yield loss were generally low, Farmers were poor at estimating the economic impact of deer damage when compared to validation data, but a number of parameters may have changed in the two years between the questionnaire distribution and validation, including changes in deer density, crop rotations, and the marked drop in grain prices, which may account for some of the inaccuracies. There were no statistically significant relationships between deer damage assessments and yield loss, either for individual species or both species combined. The relationship between Roe deer damage at the harvest assessment and Roe deer density was significant (Post et al, 2001).

Wildlife managers must consider the public’s preferences for wildlife population levels when determining management policies. 849 farmers, hunters and the general public of Maryland. USA, were surveyed in 1996 to determine their preferences for increasing, maintaining, or decreasing deer population numbers. Using a random utility theoretic framework, the factors that explain preferences such as residential location, socioeconomic characteristics, landscape damage, agricultural yield loss and vehicle accidents were analyzed. Results suggested that the majority of people benefit from deer and want to keep deer population at current levels. Other characteristics such as age, income, education, and residential location have minor or no impact on preferences. Property damage, crop loss, landscape damage, and car accidents appear to be the biggest concerns ( Curtis et al 2001).

 

11. Sika deer population in Japan

          Sika deer Cervus nippon population in eastern Hokkaido, Japan, increased rapidly during 1990-1998 . This increase appeared to have halted in 1999-2000, probably due to increased hunting and nuisance control. The period of rapid increase was associated with a disproportionately rapid increase in compensation paid for deer damage to crops. We studied changes in diet during 1990-2000, as reflected by stable isotope ratios of C and N in tooth collagen. We hypothesized that isotope ratios would demonstrate dietary shifts related to population levels and/or time, and that shifts in isotope ratios would be consistent with increasing individual  consumption of pasture grasses at higher population levels, delta 13C isotope ratios of tooth collagen in 3 year-old sika indicated a diet dominated by C3 plants throughout the period, and that forage species other than pasture grasses and dwarf bamboo Sasa nipponica ( the main crop and woodland understory plants,  respectively) were important elements. There was a significant decline in the delta 13C isotope ratio during  1990-2000 in both males and females, delta 15N values showed no trend with time for males, but increased over time in females. Indices of population (Sightings per Unit Effort, SPUE) were negatively correlated with female delta 13C, and positively correlated with female delta 15N, values indicating a shift in diet over the period , especially among females. This shift may be related to population and/or offtake levels, in particular  the rapid increase in female offtake for nuisance control and hunting during the period. The data are consistent with a relative increase in pasture grass consumption per individual at higher population levels, however, other  explanations of the data are equally plausible. Possible dietary changes, and other factors, influencing the observed shift in isotope ratios are discussed. Although statistically significant, the magnitude of dietary shifts  nevertheless appeared small, and did not provide evidence which would justify modifying the current policy, of limiting crop damage through managed population reduction to about 25% of peak levels( Halley et al 2006).

 

12.  White-tailed deer damages

          White-tailed deer (Odocoileus virginianus) may cause more damage than any other species of wildlife. These damages include crop loss, automobile and aviation collisions, disease transmission, environmental degradation, and destruction of ornamental  plantings. One practical method of controlling deer damage is the use of exclusionary fences. The relatively high cost of labor and materials required to build effective fences has limited most applications to the protection of orchards, vegetable farms, other high –value resources, and mitigation of human health and safety risks. Improvements in fence technology resulting in less expensive, yet effective fence have expanded the use of fence to manage damage caused by deer. Fence typically installed to manage white-tailed deer damage include wire or plastic mesh, electrified high-tensile steel wire, and electrified polytape or polyrope fence. They reviewed the scientific literature on fencing to determine which fence designs would be the most effective for excluding deer in a variety of situations (VerCauteren et al 2006).

          The installation of fences to protect agricultural products, natural resources, or other areas from deer (Odocoileus spp.) can be expensive and potential benefits of fencing are difficult to quantify. A rational method is needed to help evaluate whether fencing can be cost effective and which fence designs will be optimal for particular applications. They describe an interactive, dynamic simulation model that conducts economic analyses and predicts economic benefit associated with fences for crops relative to area and perimeter of protected plot, value of crop, percentage of crop damaged by deer annually prior to fencing, efficacy of fence, and costs of fence materials and labor. Users of the model can easily adjust these variables to fit their individual situations and needs. By running a series of simulations, model users can answer questions related directly to fence efficacy and cost-effectiveness (VerCauteren K et al 2006).

 

13. Corn damage by wild life

          Corn damages in USA were estimated at 6.6 per hac due to wild life. The white tailed deer was the wild animal responsible for loss. The average hacters owned by farmers were 125 out of which 55 hectares were sown corn. (Tzilkowsi et al 2002).

 

14.  Deer Damage

          Deer (Odocoileus spp.) can cause substantial damage to agricultural crops, resulting in economic losses for producers. They developed a deer activated bio-acoustic frightening device to reduce white-tailed deer (O, virginianus) damage in agricultural fields. The device considered of an infrared detection system that activated an audio component which broadcast recorded distress and alarm calls of deer. They tested the device against unprotected controls in cornfields during the silking-tasseling stage of growth in July 2001. The device was not effective in reducing damage: track-count indices (F1,4=0.02), corn yield (F1,9=1.27,P=0.289), and estimated damage levels (F1,10=0.87, P=0.374) did not differ between experimental and control fields. The size (F2,26=1,00,P=0.380), location (F2,25=0.39,P=0.684), and percent overlap (F2,25=0.20,P=0.818) of use-areas of radiomarked female deer did not differ between during and after treatment periods. They concluded that the deer-activated bio-acoustic device was not effective in protecting cornfields in this study; however, the device may be more effective in small areas such as gardens or for high value crops that do not grow tall enough to offer protective cover (Gilsdorf et al 2004).

          White –tailed deer (Odocoileus virginianus) cause millions of dollars of damage to agricultural crops annually . They tested the effectiveness of propane exploders and Electronic Guards (Pocatello Supply Depot, Pocatello, Id). For reducing deer damage in corn fields during the silking-tasseling stage of growth. Track-count indices (F2,7=0.70,P=0.532), corn yield (F2,6=0.14, P=0.873), and estimated damage levels (F2, 12=1,45 P=0.272) did not differ between experimental and control fields. The size (F2,11=0.08,P =0.924), Location  (F2,9=0.30, P=0.750), and percent overlap (F2,9=0.46, P=0.644) of use –areas of radiomarked female deer in the vicinity of experimental fields did not differ  among before, during and after 18 day treatment periods. In a related study, we placed propane exploders in cornfields within use-areas of 12 radiomarked female deer. The deer did not react appreciably to the devices; the size (F2, 17=0.08, P=0.921), location (F2,22=1.37, P=0.275), and percent overlap (f2,10=0.47, P=0.636) of deer use areas did not differ among before, during, and after 14 day treatment periods. They conclude that propane exploders and Electronic Guards have limited potential for reducing deer damage to corn at the silking-tasseling stage (Glisdorf et al 2004l.

 

          A welfare measure for wildlife damage to Ontario (Canada) field crop producers during the 1998 was. The welfare measure presented in this study provides a more accurate picture of losses from wildlife damage to agricultural. Other damage estimates based on yield loss overstate the damage since benefits from wildlife are netted out. Results for the Ontario field crop producers indicate that the magnitude of the difference between the value of the yield loss and the welfare measure of damage is approximately 50%. This difference indicates that most farmers were willing to tolerate the wildlife damage they experienced (Heigh et al 2001).

 

15. Grapevine damages

          In field trials in 1999-2000 in Gundla Pochampally, Andhra Pradesh, India , the incidence of damage to green grapevines was studied. Visits to the vines by bats begain around 45 minutes after sunset and foraging continued until 1 hour  before sunrise. Damage occurred to ripe fruit only, and increased around harvesting time, percentage damage ranged from 0 to 100% (Bhargavi et al, 2001).

 

16.   Hippo damage

          The introduction to the paper described the various ecological effects known to result from grazing, movement along paths, and wallowing by the common hippo. Hippopotamus amphibious. The study reported was carried out at Kainji Lake National Park., Nigeria, during  the dry season periods {of 1991 and 1992} . The method adopted by Agnew, A.D.Q. (East African Wildlife Journal (1966) 4, 38-46) was used to assess hippo foraging footprints at three hippo pool sites. A total of 32 footpaths were enumerated out of which 18 were located at Kaii hippo pool site, while the frequency of utilization of paths was also higher for this site relative to those in other area. The upstream-downstream trend in hippo occupancy of dry  season water pools could expose the hippo to crop damage conflicts at the peripheral areas.

 

17.  Hygo-Japan-mammal crop damages

 

          Mammals inhabiting  Hyogo consist of seven orders, 17 families and about 40 species. Except for Lagomorpha and  Artiodactyla, the remaining five orders among them include species which need some protection and they total about 55% of all species excluding extinct, introduced and feral species. Ecological information in Hyogo prefecture has been accumulated in few protection-required species there is no recent information of spatial distribution on Oriental water-shrew, Japanese noctule-bat and Japanese dormouse; and little information on Japanese shrew, Japanese horse-shoe bat, Japanese large –footed bat. Schreiber’s bent-winged bat, Japanese tube-nosed bat, common parti-colored bat, Japanese squirrel, Japanese small flying-squirrel, Japanese giant flying-squirrel, smith’s vole harvest mouse and Japanese badger. Damage and population managements is also necessary in sika deer and Japanese wild boar, to reduce their crop–damaging, and comprehensive management in Japanese black bear, an endangered local population, to prevent human-bear fatal accident. Habitat alteration due to human activities, however, has affected the population sizes and spatial distribution of all these, mammals in Hyogo. Habitat management has priority over damage. Fundamental and applied scientific studies and understanding of ecology and wildlife management science needs promotion by citizens (Mitani M 2000).

 

18. Monkey damage

 

          Forty-seven property owners in Entebbe, Uganda were questioned about vervet monkey activities on their property. The objective was to investigate the interactions between humans and vervet monkeys in an agricultural area adjacent to a forest zone. Other studies have reported that farms located within 300 m of a forested boundary probably incur the greatest risk of crop-raiding. Two other factors that may influence susceptibility to vervet crop-raiding were also examined: the types of crops grown and the types of direct preventive measures used. The effect of these two factors on vervet crop-raiding is not straight forward. However, the distance a property is located from the forest edge is an important factor influencing vervet crop raiding. Surveyed  gardens 200 m from the  forest edge received significantly less crop –raiding than farms located  100 or 50m (P=0.040,Saj et al 2001).

 

19. Bait damage

          The longevity of zinc phosphide (ZP) on whole wheat bait  was determined at the end of the “dry” and “wet” seasons,  is Western Australia.. While the total rainfall during the two trials was 74 mm and 155mm, substantial loss of ZP was recorded only after significant rainfall events. Irrespective of season, the loss of ZP from bait applied in bait stations was minimal. The maximum recorded loss was 17% and this occurred after  21 days’ exposure during the wet season where the bait stations were placed in-crop. Nevertheless, regardless of the application method, sufficient ZP always remained on the wheat bait. Theoretically  it was lethal to rats for at least 8-14 days (Twigg et al.,  2001).

20.Venezuela experience:

          In Venezuela, lethal control of wintering Dickcissels (Spiza Americana) is considered a threat to the species survival. To help farmers protect their rice and sorghum crops from by Dickcissels and to minimize the killing of large numbers of these birds, alternative non-lethal crop protection measures are needed. To that end, the responses of captive Dickcissels to three bird-repellent chemicals (anthraquinone,methyl anthranilate and methiocarb) applied to rice seed were evaluated. In one-cup feeding trials, treatments of methiocarb (0.05% g/g, applied as Mesurol 75%  wettable powder) and anthraquinone (0.5%, applied as Flight Control) reduced consumption of rice by 70% relative to pretreatment consumption. Other anthraquinone treatments (0.05,0.1%) and methyl authranilate (0.05%) were inrffective. In two –cup trials, with untreated millet as the alternative food, consumption of rice treated with 0.05 and 0.1%  anthraquinone was reduced by 90% relative to pretreatment levels. Overall, Dickcissels responded to the repellents similarly to the red-winged blackbird (Agelaius phoeniceus). Because Flight Control has been used successfully to reduce blackbird use of rice fields in the USA, the prospect is good for successful reduction of damage to repening rice by Dickcissels in Venezuela, particularly if repellent use is coupled with the establishment of alternative feeding sites ( Avery et al 2001). Deer selected carrots over all green manure crops.

 

21. Nilgai damages in India

           Crop-damage by nilgai has been widely reported from India.  Are give Nilgai is for increasing in this region. Lack of natural predators, deforestation overgrazing and the protection of these animals from Hindu communities are reasons for their overpopulation. Tree cover of Acacia are generally used by nilgai as a day time shelter but not food,  therefore it goes for crop-raiding in the late evening and at night, jumping across 6-7 feet high stone wall, barbed fencing and fences of dead or live thorny plant material and any other fencing/barrier made to protect the crop-. Due to habit of both grazing as well as browsing they devore every kind of farm species (both rabi and kharif crops). It has been observed that eating less but destroying more by trampling and causing damage are therefore regarded as serious mammalian crop pest and farmers wants to get ride of this unconventional pest. The farmers chase them away by just following them by making loud sound by crackers or air gun fires, following through tractors, empty tin or dried pumpkin filled with small stones and connected with strings. Technically, carrots(enclosures), trenching or power fencing are suggested to mitigate the crop damage. Secondly, animals could be translocated to wildlife sanctuaries from the sites they seen overcrowded or severe crop raiding problems (Goyal et al 2000).

 

22.  Pesticides and wildlife

A range of monitoring activities has shown impacts of anticholinesterase pesticides on UK wildlife, and continued risks are evident from laboratory and field experiments, together with the scale of use in the field. Along with other broad spectrum insecticides, many organophosphates have adverse direct effects on non-target arthropods in farmland, and so are likely to contribute towards indirect effects of pesticides on farmland biodiversity. The anticholinesterase insecticides have both lethal and sublethal effects on aquatic wildlife, however the history of recent incidents of damage to river ecology following the wider use of synthetic pyrethroid sheep dips, illustrates the need to consider the implications of changes in the use of alternative products when reviewing these insecticides ( Burn 2000).

 

          The use of anthraguinone-based flight control and methyl anthranilate-based non toxic avian foraging repellent we used to avoid crop damage by sandhill cranes. Thought both repellents were effective at deterring cranes from treated corn, neither has been tested on corn under field conditions. (Blackwell et al 2001).

          Oak seedlings were scientifically raised. Seedling mortality and wild life browse damages were minimal when certain herbicide mixture was used. Biologically and aesthetically, the procedure was extremely successful (Ezell et al 1999).

          Pre-commercially thinned (forests are less prone to moose damage (McLaren et al, 2000).

 

23.  Pesticide use in conflicts

          Pesticides can cause damage to man and beneficial organism. Some sub-lethal effects of pesticides were studied in birds with a view to identifying  characteristic biochemical responses that may be useful for the monitoring of exposure to sub-lethal levels in the field. Pesticides were used; demeton-S-methyl, (DSM),chlorpyriphos, chlorfenviphos, triazophos, pirimicarb, methiocarb and permethrin. Blood was collected before dosing, and 2,6,24,48 and 72 hours after the treatment from the brachial vein of birds. Enzyme, activities were assayed in the plasma or serum samples obtained. The assays used were GOT,MHD, GDH, SDH,GAMMA GT and ChE. The results showed an increase in plasma and serum GOT and gamma-GT levels were found in all animals treated with the previous pesticides. The level of ChE increased in birds after treatment with permethrin. It was concluded that the pesticides cause structural and functional changes in the liver and also, the measurement of the previous parameter activities may be useful for assessing exposure and sub-lethal effects of pesticides on the wildlife (Dahamna et al 2004).

 

 

24. IPM and crop losses

          The queensland sugar, industry has recently implemented a comprehensive integrated pest management (IPM) system to minimize crop losses from two antive rodent species, Rattus sordidus (canefield rat) and Melomy burtoni (climbing rat). These species inflicted approximately $25M of damage in a major outbreak in the  1999-2000 seasons. Both of these rodents are listed as common wildlife under the schedules of the queensland nature Conservation (Wildlife) Regulation 1994. The IPM programme is based on understanding the ecology and biology of each species. It incorporates a large-scale monitoring programme aimed at providing early warning of imminent rodent build up to avert major outbreaks. The industry has also  developed a memorandum of understanding with Queensland State Government, which delivers on the industry’s pest management needs, while providing an improved system of accountability for the taking of two of Queenslands native wildlife species. The consensus reached between the cooperating parties (The Bureau of sugar Experiment Stations, CANEGROWERS, regionally-based Cane Productivity Services, and the outcomes can be negotiated between rural industry and environmental interests (Hunt et al 2004)  .

          In Areas around Lake Mburo National Park ,large wild animals wander in close proximity to human settlement . This poses serious conflict in terms of crop damage. The integration of conservation with other land uses is difficult where densely settled agricultural land surrounds a protected area potentially containing problem animals, as is the case for several parks in Africa and Asia. The intensity of crop raiding was quantified through the use of random crop quadrants/plots and area estimation techniques in a portion of raided fields. The animal species concerned were documented from observations, footprints and any other marks left behind. Three variables were tested as predictors of damage; human population density, distance from the park boundary and season. In this study data is presented regarding crop loss in the different seasons of the year, analysis of crop damage variation and animal species involved in crop loss. A diverse assemblage of animals foraged on subsistence crops and analysis of crop damage revealed significant crop depreciation by wildlife( Kagoro et al 2004).

 

 

 

25.  Hawai Pest

          The apple snail, P.canaliculata, is an aquatic freshwater snail native to South America, Originally imported to Hawai’i as pets for the aquarium trade, they were soon introduced into wetland plots known as “lo’s” where taro (Colocasia esculenta), an economically and culturally significant crop, is grown. Some individuals reasoned that the snails, being edible, could be harvested as food, and that raising the snails along with the taro in the “Io’s” would provide income supplemental to the taro harvest with minimum additional input. This introduction of snails into the taro “lo’i” however, proved to be a disaster. Farmers failed to take into account the voracity , reproductive potential, and rapid growth of the snails. Because of the ideal conditions in the taro “lo’i”, the snails  multiplied rapidly and fed heavily on the taro shoots and corns in many cases, destroying a complete crop before harvest time. Hindisight has shown that the snails are dissipated via the irrigation system throughout the “lo’i” and then spread to the surrounding wetland areas. Large breeding populations are now established in wetland areas on the islands of Hawai’e, O’ahu, Kaua’I, and Maui. Some of  these wetlands are wildlife preserves with state and federal mandates that restrict the potential methods of eradication. Background information is provided on both P.canaliculata and taro to fully explain the challenges and opportunities that this situation presents (Tamaru et al 2006).

 

26.  Chemical repellents

          Chemical feeding repellents applied to ripening sunflower might help reduce blackbird (lcteridae) damage, which is a chronic agricultural problems from seed information harvest. However, cost are high to develop and register new repellents for agricultural use. In 2003 and 2004, we evaluated feeding repellency of  8 pesticides registered by the Environmental Protection Agency for use in sunflower. Caged red-winged blackbirds (Agelaius phoeniceus) were fed unshelled sunflower seeds treated with the following pesticides: 5 pyrethroid insecticides, an organochlorine, an organophosphorus, and a gungicide. Compared to untreated refernce groups, feeding rates were reduced for 4 of the 5 pyrethroid insecticides. Only the organophosphorus (chlorpyrifos), however, significantly decreased feeding rates. More research on repellency effects of this product in field efficacy trials is probably warranted based on the results of our cage experiments. Depending on timing of application, registered insecticides with blackbird feeding repellency could provide supplemental economic benefits to sunflower producers through dual purpose use ((Linz et al 2006).

 

27. Persistent organic pollutants (POPS)

          Persistent organic pollutants (POPs) have spread throughout the global environment to threaten human health and damage ecosystems, with evidence of POPs contamination in wildlife, human blood, and breast milk documented worldwide. Based on data from the US Food and Drug Administration, this article provides a brief overview of POPs residues in common foods in the USA food supply. The analysis focuses on 12 chemical compounds now targeted for an international phase out under the Stockholm convention on POPs. The available information indicates that POPs residues are present in virtually all categories of foods, including baked goods, fruit, vegetables, meat, poultry, and dairy products. Residues of five or more persistent toxic chemicals in a single food item are not unusual, with the most commonly found POPs being the pesticides DDT ( and its metabolites, such as DDE) and dieldrin. Estimated daily doses of dieldrin alone exceed the US Environmental Protection Agency and US Agency for Toxic Substances Disease Control reference dose for children. Given the widespread occurrence of POPs in the food supply and the serious health risks associated with even extremely small levels of exposure, prevention of further food contamination must be a national health policy priority in every country. Implementation of the Stockholm Convention will prevent further accumulation of persistent toxic chemicals in food. Early ratification and rapid implementation of this treaty should be an urgent priority for all governments (Schafer et al 2002).

 

28. Netherland experiences

          Traditionally, pink-footed geese Anser Brachyrhynchus wintering in Denmark, the Netherlands and Belgium have used the Danish sites only during mild winter, rapidly moving southwards in case of cold spells. Since the 1980s, an increasing number of geese have remained on the Danish wintering grounds despite cold spells, foraging on pastures Because winter wheat represented a reliable and profitable food source even in sever winter, the recent change in Agricultural practice has enhanced the development of a new wintering strategy of pink-footed geese, allowing a northward expansion of their winter range. Potentially, this will increase the crop damage conflict and may lead to further population growth ( Therkidsen et al 2000).

          Enclosure trials near Huron, CA in the San Joaquin Valley from 12 to 23 January 1999 , determine the efficacy of Flight Control TM (50% anthraquinone) and Mesurol R (75% methiocarb) in preventing horned lark damage to lettuce seedlings. Flight control TM (FC) and Mesurol R were evaluated as foliar sprays at application rates of 2.79 and 2.27 kg ha-1, respectively. Horned lark damage to lettuce seedlings treated with anthraquinone was greater (p=0.015) than for methiocarb R, 60 versus 20% , respectively, and seedlings in control plots were 100% destroyed. While this level of damage is probably unacceptable to lettuce growers, it should be remembered that the enclosure situation caused an artificially high bird pressure on the crop. Further studies in open fields under a more normal bird pressure are warranted ( York et al 2000).

 

29. Ozone injury

          Incidence and severity of visible foliar ozone injury on cutleaf coneflower (Rudbeckia laciniata L.) and crown-bread (Verbesina Occidentalis Walt). Were determined .It is thus a matter of consideration that zone injury may harm vegetation harmed by browsing or even cutting. Ozone injury was greatest on the lower leaves for both species sampled with over 95% of the injured leaves occurring on the lower 50% of the plant. This is the first report of foliar ozone injury on these plant species in situ, in the Park, illustrating the great variability in symptom expression with time, and within and between populations ( Chappelka et al 2003).

 

30. Protected arrears and humans

          Knowledge of conflicts between people and protected areas is required for the design of sustainable conservation strategies for the management of most protected areas. The study identifies the causes of conflicts between local people and the Benous Wildlife Conservation Area (BWCA), which includes the Benous National Park, In northern Cameroon. Informal interviews and questionnaires were administered to 114 households in three communities, and to 17 park staff and 7 professional hunting guides from July –October 1997. Crop damage affected 86% of the surveyed household, with 31% of crop income lost on average, and with the damage varying significantly between communities. Elephants, baboons, patas monkeys. Warthogs and green parrots accounted for 97% of crop damage, with the staple food maize and  millet being most affected. Of  the respondents 27% experienced livestock depredation, with 18% of livestock income lost  on average. The civet cat was the main predator. The involvement of local people in illegal activities, their  lack of access to natural resources, and damage by wildlife were identified as principal causes of conflicts. Local people, park staff and professional hunting guides had diverse and differing perceptions about the causes of the conflicts and made various suggestions for reduction of wildlife damage including animal scaring and controlled shooting. We conclude that, under current wildlife policy, conflict between people and BWCA  (Bonous Wildlife Conservation area) is difficult to resolve. To reduce conflicts and promote sustainable conservation, we suggest co-management of wildlife involving all stakeholders, establishment of crop damage control teams, and promotion of tangible benefits to  local people. There may be a requirement for site –specificity in management strategies (Weladji et al 2003).

 

31. Low technology use to avoid damages

           It is suggested that an integrated, community-based, low technological approach will be the most sustainable solution to this conflict ( Osborn et al 2003).

          Blackbirds (lcteridae) annually damage US$5-8 million of ripening sunflower in the northern Great Plains. Baiting blackbirds with avicide-treated rice during spring migration might reduce the regional breeding populations. birds can be successfully baited with avicide-treated rice placed in corn stubble (Linz et al 2003).

            Plant debris accumulation is viewed as a key factor determining small mammal abundance and potential damage in low-till agricultural ((Stermer et al 2003) areas.

          The projected total value of crop yield losses due to wildlife damage for buffer zone villages located in Garhwal Himalaya in about Rs.5 38 620 (US$15 389). Besides food grain, horticultural crops i.e apple, also suffered. Major wildlife

Actual State of Organic Agriculture

ACTUAL STATE OF ORGANIC AGRICULTURE  

         IN INDIA AND OTHER COUNTRIES 

 

                                            Dr.Ashok K. Panigrahi and Mrs.Kusum Misra

 

 

            Organic agriculture is about more than just growing crops without using either chemical fertilizers and synthetic pesticides, rather it a holistic approach to the very system of farming that restores, maintains and enhances economical sustainability and ecological balance generating non toxic, healthy and tasty food or medicine or dye with natural fragrance and colour.

             In today’s world most organic growers since believe in biodiversity, they avoid GM varieties, whether crops or seeds or plants or animals. They use no chemical either for soil fertility or for pest control, no chemical either for their growth or for their protection except the medicines that too only when the situation is very bad and beyond control.

 

AN OVERVIEW

 

            Organic agriculture is currently being practiced in more than 100 countries the world over. The ill effects of agrochemicals used for last several decades have changed the minds of consumers in different countries who are now buying or willing to bye organic food stuffs with high premium.

            Policy makers are now promoting organic agriculture for several different reasons such as soil health, sustaining rural economy and creating better environment. The global organic area is estimated at 26 million hectare with 61 standards and 364    

certification bodies.

 

           The world organic market is estimated at 26 billion US $.

 

          The certified organic area in India is estimated at 2.5 million hectare but non-certified area is much more.

 

HISTORICAL PERSPECTIVE

Organic agriculture is being practiced in India since the beginning of agriculture in this country and it continued as such till Green Revolution was introduced in this country in the mid sixties.

 

There is a brief mention of organic agriculture in ancient literatures like the Rigveda, Ramayana, Mahabharata and Kautilya Arthshastra etc.

 

Sir Albert Howard was the first industrial agriculturist who was brought in to India by the British to teach the Indian farmers the use of agrochemicals but he ended up in learning the organic agriculture from Indian farmers, developed the Indore process and went on to establish the symbiotic fungal bridge between the humus in the soil and the sap of the plants through the mycorrhizal associations. He wrote in his, An Agricultural Testament, “Since industrial revolution, agriculture has become unbalance, the land is in revolt, diseases of all kinds are on the increase, the nature is removing the worn out soil by erosion.”

 

 

AGRICULTURE IN ANCIENT INDIA

 

1. Oldest practice              10,000 years ago dating back to Neolithic age by ancient
                                          civilization like Mesopotamia, Hwang Ho basin etc.

2. Ramayana                     All dead things returned to earth that in nourish soil and life  3. Mahabharata                5500 B.C., Kamadhenu – the sacred cow, had role in not            

                                         only in human life but also in soil fertility

4. Kautilya Arthshastra    300 B.C., use of several manures made of the excreta of

                                        domesticated animals and oil cake

5. Brihad Sanhita              Methods of choosing manures for crops and manuring

6. Rigveda                        2,500-1,500 B.C., green manure, use of dung of goat, sheep,
                                         cow etc.

 

LARGE SCALE USE OF CHEMICALS IN AGRICULTURE IN INDIA

 

US Noble laureate Norman Borlaug, the creator of the famous dwarf wheat variety in Mexico, visited India in 1957. In a press conference he said, “Were I been a member of the Indian Parliament I would leapt from my seat every fifteen minutes and yell at the top of my voice, fertilizers, give farmers more fertilizers.” The fact is that, between the fifties and sixties, in the independent India, there was a gap between the demand and production of food. To meet this, the Indian planners under the influence of the US institutions like the Ford and Rockefeller Foundations and the US food specialist Norman Borlaug, conceived the idea of paradigm shift in agriculture, from natural to chemical, from natives to high brids and high yields, the seeds of which gained popularity under the global brand name of “miracle seeds,” having the ability to soak up agrochemicals developed at that point of time. This was a global phenomenon and it helped in the global increases in food out puts instantly. To day the world food grain production is estimated at 2100 million tones and it is mostly based on use of agrochemicals, artificial chemical fertilizers and synthetic pesticides. However, the impacts of these agro chemicals, the artificial chemical fertilizers and synthetic pesticides are well observable. No data have been published by any the Indian agency like the US Environment Protection Agency (USEPA). The USEPA revealed in 1991 that the projected estimate of methane emission from the Indian paddy fields amounted to 37.8 metric tones per year, thus accusing Indian paddy cultivators in adding to the global green house gas accumulation as methane is also considered as a green house gas. Consequently in India more emphasis was attached to shift to non conventional agriculture and keep paddy cultivation limited to 47% of total arable land (National Agriculture Policy, 2000). Use of artificial chemical fertilizers especially N- fertilizers always invite the agricultural pests leading to applications of pesticides, especially synthetic pesticides and both of these pollute the environment substantially.

 

The global fertilizer use (in Kg/ha)

Korea                          -           357 kg             Japan               -           247 kg

Netherlands                  –           172 kg             Bangladesh       -          158 kg

Germany                      -           153 kg             India                 -             89 kg

 

 

The sinister logic of recommendation of the use of chemical fertilizers:

Plant requires 17 essential nutrients divided under two groups:

1. Macro nutrients- those required by plants in large amounts and                  

2. Micro nutrients-those required by plants in small amounts

Regardless of the sources, plants absorb all nutrients in inorganic forms only.           The 3 Macro or major primary nutrients are absorbed as under -

                        Nitrogen (N)       as      Ammonia, Nitrate and Nitrite                 

                        Phosphorus (P)   as     P2O5 (available phosphorus)                  
                        Potash  (K)          as     K2O   (available potash)

 The 3 macro secondary nutrients include such substances as Calcium (Ca), Magnesium (Mg) and Sulphur (S) which are naturally available in the soil and manures.

Micronutrients or minor plant nutrients are in fact trace elements as Iron(Fe), Manganese(Mn), Zinc(Zn), Copper(Cu), Boron(B), Molybdenum(Mo) and  Cobalt(Co) and like the secondary macro nutrients, are supposed to be available in the soil and manures. Although there is nothing organic in the nutrient absorption by plants but plant up take is surely influenced by the source of origin of the said nutrients, it is better if it is from the organic source, as the availability is modest and release is delayed but prolonged and the nutrients do not influence each other’s up take. In the chemical process, excessive applications of nitrogenous fertilizers prevent phosphorus and potash up take by plants.

State of facts

Intensive farming, said to be required to meet the increasing food demand of the growing population, exhaust natural soil fertility and distort soil’s natural balance.

It is suggested, inorganics have to be selectively added to the soil to maintain the required plant nutrition. But their ills are never assessed nor taken care of.

In the green revolution era throughout the world, the crop plants were basically protected through the use of biocides, pesticides, fungicides etc.and its impacts were never assessed.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       

Use of synthetic pesticide (in kg/ ha.) in USA, Japan, Korea, China and India are 1.5, 10.8, 6.6, 2.25 and 0.38 kg, respectively.

The uses of synthetic pesticides in the last few decades have become one of the essential inputs of modern farming, but consequences are evidently disastrous.

 

WHY   SHOULD WE EMBRACE ORGANIC FARMING?

Because food safety is as important as food security

DO WE KNOW HOW THE ARTIFICIAL CHEMICAL FERTILIZERS HARM US!

 They—-

v     Interfere and eliminate nutrition producing microbes (bacteria fungi and worms) from soil.

v     Impede and set in imbalance the entire mineral and micronutrient pattern in crop plants.

v     Excess of N- fertilizer in soil impair K uptake by crop plants and they lack K component in their tissues.

v     Excess of K applications decrease the amount of Vitamin-C (ascorbic acid) and carotene (pre Vitamin A) in crop plants.

v     Super phosphate applications cause deficiency of Cu and Zn in crop plants.

v     Their applications reduce the natural resistance to disease and pest in crop plants

v     N-fertilizer applications though enhance crop yield, it is in terms of carbohydrates. There occurs a deficiency in protein content by 20-25% w/w and the amino acid balance is greatly impaired, thus lowering the protein quality.

v     N- fertilizers (NO3,NO2 and NH3+) act as toxins in soil, percolated into underground water tables,NO3 and NO2 cause Methaemoglobinaemia (Methaemoglobin occurring in excess of normal 0.8%) which at 20% cause headache and giddiness, at 60% loss of consciousness and around 80%, death in adult human beings. Affected new borne turn blue and die (blue baby syndrome).

v     N- Fertilizers (NOx) reduce O3 by 3.5% by reducing NO (NO+O3      NO2+O2). A one percent of O3 depletion cause increase 2% of U-V radiation, 10% decreases of O3 in stratosphere increase Melanoma (skin cancer) by 20-30% besides causing high occurrence of cataracts, destruction of immunity, vegetation and sea-life.

v     Concentration of NO2 at 6.0mg/kg in excess of 2mg/kg of air cause leaf damage, impaired photosynthetic activity in many plants. At a higher concentration, causes burning sensation of mucous membranes. NO3 at 800mg/ltr.of water caused cattle deaths in epidemic form in Rajasthan in 1976.

THIS IS HOW THE SYNTHETIC PESTICIDES HARM US -

v     These are generally bionondegradables, introduced into the ecosystem, they play havoc, either as hazardous or toxicants or both.

v     Aimed at eliminating the pests, they end up in increasing their pesticide-resistance as most of the pests have as many as 10-30 life cycles in a year.

v     The table given below shows changes in cotton insecticide use(in mln.pounds),from USDA chemical use survey( It is to note that Bt cotton was introduced in US in 1996)

v     Percolated into the underground water tables, cause pesticide pollution, the recent Coca cola- Pepsi and bottled water episodes are the glaring examples. Once consumed, they have one way traffic in the human (animal) vital tissues.

v     According to Pearson (1985) pesticide related deaths in developing countries are estimated at 10,000/yr. nearly 1.5-2 million persons in these countries suffer from acute poisoning related to pesticide use and consumption, whether knowingly or unknowingly.

FACTS FAVOURING ORGANIC FARMING

Organic proponents are against fertilizer inputs due to the following reasons.

  1. Fertilizer use is only 100-160 years old.
  2. Not willing to accept the claim that fertilizers enhanced global food production.
  3. Lot of plants on road sides, hills and deserts are surviving with humus from biomass years after years, without any fertilizers being ever applied.
  4. Fertilizer is from the brain of the industrial lobby only, and is neither for the advantage of the farmer-consumer nor the environment.
  5. Crop produced with chemicals contains heavy metals and other contaminants, hence, not well for health.
  6. Agrochemicals cause disease and death due to excess nitrate and pesticide residues.
  7. The so called food produced through the use of agrochemicals is devoid of vital minerals and vitamins which, in turn, incapacitate the enzyme systems so vital for proper body functions necessitating their additions to food and medicines.
  8. Fertilizers like Urea and DAP contain heavy metals like lead and cadmium.

Why organically grown food are preferred over Inorganically grown food:-

Organically grown food contains more vitamins, minerals, enzymes, trace elements and even cancer fighting antioxidants than conventionally grown food, revealed a two years study made in Chicago, USA. It was also observed that the average level of minerals were much higher in the organically grown food than in the conventionally grown food. Besides, the organically grown food always tastes far better and has a longer keeping quality even without refrigeration.

Definition and objectives of organic agriculture

The concept of organic agriculture is often misconceived and misrepresented

 

The organic agriculture in real sense is the one that envisages a comprehensive management approach to sustainably improve the soil fertility and control the pests so as to improve the B: C ratio.

 

Organic agriculture is a production system which avoids or excludes the use of all synthetic compounded fertilizers, pesticides, growth regulators and live stock feed additives.

 

It relies on crop rotations, legumes, green manures, crop residues, animal manures, off farm organic wastes, vermi technology and methods of botanical and biological pest control.

 

Organic farming is the concept of farm as an organism, in which all the components – soil minerals, organic matters, micro organisms, insects, plants, animals and humans – interact to create a coherent self regulating and stable whole (Lampkin, 1999).

 

Sustainable agriculture prohibits reliance on all purchased inputs, whether chemical or organic and thus improves the B: C ratio. 

     

Organic farming is propagated to make agriculture sustainable, hence, is a holistic production system with enhanced B: C ratio.

 

   International federation of organic agriculture movement (IFOAM) stresses and supports the development of self supporting system on local and regional basis.

Principles of organic agriculture

The main principles are as follows:

  1. To maintain long term soil fertility with ecological balance.
  2. To avoid all forms of pollution resulting from agricultural operations.
  3. To produce toxin free food stuff of high nutritional quality in sufficient quantity and better taste.
  4. To reduce the use of fossil energy in agriculture practice to a minimum.
  5. To give the live stocks condition of life akin to their physiological needs.
  6. To enable farmers to earn a living through their work and improve their economic standards so as to make agriculture sustainable and farmers, the world over, dignified human beings.

The four pillars of organic agriculture

  1. Organic standard
  2. Certification/regulatory mechanism
  3. Technology packages
  4. Market network

Standard and certification

The most important component of organic farming in modern era is certification programme which consist of

  1. Standard (rules)
  2. Inspection (checking whether rules implemented)
  3. Certification (judgement)

Only by these three norms, organic farming can be distinguished from other methods of sustainable agriculture.

These standards defined what can be leveled “certified organic” and sold commercially as such.

In fact, certification in organic agriculture generally refers to third party certification. Third party implies that it is not done by either producer (1st party) or the buyer (2nd party).

The system includes farm inspectors and audit trails (checking of records).

Certificate is valid only if it is done by accredited certifying agency.

Certification programme varies from country to country because of the differences in environmental, climatic, social and cultural factors.

Standard

Globally, there are more than 60 standards. International Federation for Organic Agricultural Movement (IFOAM) (Headquarter – Germany), first established                                                                                                                                                                                                                                                                                                                   accreditation programme in 1992 to accredit certifying bodies and to setup Intl. Organic Accr. Services (IOAS). FAO, WHO and Inter governmental bodies, 1962 laid out a set of guidelines for organic productions mostly in the EU states. In 1991 Demeter international a world wide network and Japan Agriculture Standard (JAS) were set up..

 The statutory norms of product labeling depends on the destination to which the same is to be exported or the destined market of sale such as the US, EU, or Japan.

  1. In the EU states, it must confer to EEC regulation no. 2092/91.
  2. In the US, it must confer to the UASDA standards for organic foods.
  3. In Japan, it must confer to Japanese Agriculture Standards (JAS) for organic products.

Highly accepted Certifications

           It includes those from agencies and associations such as CODEX and IFOAM (International Federation for Organic Agricultural Movement) etc.They are accepted in the US, EU states and Japan, the most important organic markets.

           The Ministry of Commerce, Government of India, in 2000 launched the National Programme for Organic Production (NPOP) to ensure focused and well directed development of organic agriculture in India. A national steering committee (NSC) was formed comprising of APEDA(Agricultural and Processed food Export Development Authority), Spices Board, Coffee Board and various government and private organizations associated with the organic movement to formulate the national standards for organic agriculture with the following guide lines;

  • No harmful chemicals have been applied to the land for at least 3 years
  • The farmer and processor have annual certification inspections
  • They have maintained detailed records of their practices
  • They use eco-friendly methods and substances for soil fertility and pest control.

On the recommendations of the National steering committee, the government has constituted the accreditation agencies for the NPOP. The works of these agencies are:

  • Drawing up procedures for evaluation and accreditation of certification programmes
  • Formulating procedures for evaluation of the agencies implementing the programmes.

The following agencies have been approved as accreditation agencies by the Government of India;

  1. APEDA, 2. Spices Board, 3. Coffee Board, 4. Tea Board, 5. Coconut Development Board and 6. The Directorate of Cashew and Cocoa Development.

As per report, today there are 364 certification bodies across the world.

Technology packages

Conventional practices can’t be followed for growing crops organically. It includes following

a)       Land preparation

b)       Selection of variety

c)       Organic fertilization

d)       Biological control of pests – diseases – weed

e)       Harvest storage etc.

Some countries have developed package of practices for some selected crops but there is an ample scope to refine this package with scientific methods and practices.

Market network

It is expected that organic produce should fetch a greater market premium as compared to the traditional one and there should be definite market to buy the produce at a higher price.

The basic focus of organic agriculture should be

  1. To produce  farm products for the home i.e., internal consumption and
  2. For the markets, basically for export, since this will fetch more revenue.

Global scenario of organic agriculture

About 100 countries of the world are in organic agriculture and area under organic. is increasing. As per a study made in2004, by the Foundation of Ecology and Agriculture (FOUL), the total global area under organic is about 24 million hectare.

ORGANIC AGRICULTURE IN INDIA

In year 2000, the National Agriculture Policy was framed and following that,

 

  1. Planning Commission constituted a steering group on agriculture who, in turn, identified that organic farming should be taken up as a major thrust area under the 10th Plan. The region included NE rainfed area and in the areas where the consumption of agro-chemical is low or negligible like Uttranchal.
  2. The traditional knowledge of agriculture relating to organic farming was re-assessed and its scientific up gradation was done.
  3. DAC constituted a Task Force on organic farming which recommended the motion of organic farming.
  4. Ministry of Commerce launched a national organic programme in April, 2000 and APEDA (Ag. Pro. Food products Exports Dev. Authority) was to implement the national programme for organic production. APEDA then set the followings-

1. National standard   2.  Accreditation criteria

3. Inspection and certification agency,  4.  Accreditation procedure

5. Inspection and certification procedure as have been approved by   

    the National Screening Committee

India’s advantages in organic agriculture

India is endowed with diverse forms of nutrients in different soil types as available in different parts of the country which help in organic cultivation.

Farmers in most parts still depend on the animals and biodiversity for agriculture

Use of chemicals in agriculture in most parts is much below the prescribed doses; in the north-east states, agrochemicals have been selectively barred since long.

Availability of organic nutritional inputs in India as estimated by NCOF, Ghaziabad is as follows:

 

  1. Crop residue (3.865 billion tones) 2.  Animal dung (3.854 million tones)

3.  Green manure (0.223 million tones) 4. Bio-fertilizer (0.3670 million tones)

5.  Besides it has enough scope for both ancient and modern method of organic agriculture using Nadep compost, Vermi compost and other such practices.

i)    Soil fertility

     a.)   Sanjeevan System, derived from the Indian traditional knowledge system,    

essentially promotes the growth of soil microbes to a super active form through  the spray of alcoholic extracts, called “amruta” of 2 Ficus plants on composts of all kinds. The matter has been proved at Sanjeevani Sugar Factory, Kopergaon, Maharashtra, where microbial count increased to 1012  in 15 days.

b.)  Panchagabya, recommended by the Indian knowledge system, is used mostly in south India as a foliar spray for plant growth (Stock solution = 5 kg fresh cow dung  + 3 liter cow urine + 2 liter cow milk + 1 liter cow ghee + 2 liter cow milk curd + 3 liter sugar cane juice + 3 liter tender coconut water + 12 ripe bananas, kept in an earthen pot, stirred vigorously once in the morning for 15 days, 3% aqueous solution is sprayed on all crops to revive the dieing crop and envigorous the healthy crop).

c.)  Agnihotra, is an ancient Vedic method, revived recently by plant scientists and is adopted widely around the world for all crops and even for waste land reclamations.(Ingredients include a pyramidal copper vessel, few dry cow dung cakes, little cow ghee, few rice grains, a copper spoon. The dung cakes are ignited at the field every day at Sun rise and Sun set with the recitation of 2 Sanskrit mantras in praise of the Sun and fire and ash so gathered, called the “miracle powder” acts as both growth promoter and insecticide when sprayed on the field.

d)   Vermi compost or more precisely worm-cast applications. Culture and collection of worm casts of select varieties of earthworms, both native and nativised, are rich in plant nutrients and plant food generating microbes. Its applications in the farm soil help crop plants grow, flower and fruit properly.

      Raw animal dungs and decaying biodiversity make up the food of the earthworms that grow in shady moist places.

e.)  Other minor methods such as – Soil collected from the the Banyan tree surroundings and Animal Horn Manures etc.are also used in many parts.

ii)   Pest control     

Botanicals (plant derived materials), Biological pest control agents (predatory, parasitic and parasitoidic organisms) and bio pesticides (virus and bacteria) are used to control the agricultural pests. Among all plants, Azadirachta indica,

      which contains azadirachtin is the best because it is a mixture of more than 150     

      active principles, or terpenoids against which pests can not develop resistance.

      Area

i)    Around 76000 hectare area comes under certified organic farming

ii)   2.4 million hectare is certified forest area for collection of wild herbs.

iii)   Uttranchal and Sikkim have declared themselves organic states

iv)  In Maharashtra more than 50000 hectare of which 10000 hectare is certified

v)   Karnataka, more than 1513 hectare

vi)  Most of the dry zones practice organic farming

vii)  Other states are also promoting organic farming like Rajasthan, TN, Kerala, M.P., HP and Gujarat.

National Standards

Under NPOP, GoI has developed national standard for organic products. Ministry of Agriculture has accepted this standard.

  1. Laid on policy for development and certification of organic product
  2. Facilitate certification of organic products confirming to the standards of the national programme
  3. Institute a logo and prescribe its award by accrediting bodies on products qualifying for bearing India organic level
  4. A national steering committee comprising Ministry of Commerce, Ministry of Agriculture, APEDA, National Organic Products Board, Spices Board, Coffee Board, Tea Board, and various other government and private organization associated with the organic movement is monitoring the overall organic activity under NPOP in India.
  5. The NPOP standard has got equivalency with the standard of EU commission

      and is acceptable in EU countries. The same with USA, is under process.
