A brief global review to asses the damage caused to cultivated crops by wild animals around the world. The review was attempted in response to a recommendation of ICAR Regional Committee No.1 held in Oct, 2007 at Solan, H.p. presided over by Hon’ble Director General, ICAR Dr. Mangala Rai inauguration was chaired by Hon’ble Agriculture Minister J&K, Jenab Ab. Aziz Zargar.

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
