Wildlife-Human Conflicts impacting Global Food Security: A challenge and it's Mitigation Strategies.
The Human population has exceeded the mark of 7.8 billion
which is interdependent on natural resources for their sustenance. For our
survival we need food and with the advancement of technology and food demand,
it requires more agricultural land to satisfy our needs. Global Food Security
is the state of having
reliable access to enough affordable, nutritious food. Today, we are facing the Global Food Security issue which has variable causes and miserable consequences
on human health. Wildlife-Human Conflict is one of the causes, which impacts
considerable percent of Global Crop Land which leads to economic loss to the
farmers.
Forest
dwellers have co-existed with wildlife populations since ages. As the land use
changed with time it affected the patterns of wildlife habitats. The expansion of
agriculture has been one of humanity’s largest impacts on the
environment. According to the FAO, global agricultural land is increasing
with the increasing food demand and it will cross 1.66 billion
hectares (4.1×109 acres) in 2050.

Why wildlife-human conflicts are rising?
The
problems lie in our unsustainable practices and methods for land utilization.
The agricultural lands are as important as wildlife habitats. The problem
elevated when we started grabbing wildlife habitats for agriculture and setting
up human habitations. This greeted the problem of human-wildlife conflicts.
Wild animals including large mammals as well as small animals devastates crop
lands of poor farmers. As mammals need large area for their survival, they
dislocate from one habitat to another for food, mating and other activities.
But most of the lands are utilized by farmers near wild habitats, they jumped
into their farms and destroy their yearly income in one go. The human-wildlife
conflicts in case of agricultural land destruction is a global issue. Countries
like South Africa, India, Kenya, Cambodia, Sri Lanka such cases are common.

They can damage the
plants by feeding on plant parts or simply by running
over the field and trampling over the crops. Therefore, wild
animals may easily cause significant yield losses and
provoke additional financial problems. Field crops
provide a dependable and readily accessible source of food for primates coping
with habitat loss. It has transformed habitats
and is one of the greatest pressures for biodiversity: of the 28,000 species
evaluated to be threatened with extinction on the IUCN Red List, agriculture is listed as
a threat for 24,000 of them
Species causing crop damages range from elephant’s wild birds, monkeys,
squirrels, deer, parakeet, wild dogs, foxes, deer, and many others like Nilgai.
On 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 hectare
annually. Therefore, by these estimates, the damages are spectacular and
economically important. A survey of 2500
farms in the UK revealed that deer damaged 69% (n=192) cereal crops. This
damage cost £500 per annum per farm. Damages varied with deer density. In the
USA too deer damages comprised of crop loss, landscape damages. Nilgai damages
along with deer damages are common in India too. 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 behavior of them inflicts ozone injury to the young
sapling, so precious for the growth of trees in Indian semi-arid farms. Elephants induce considerable crop
damage risks, shocks and stresses on subsistence farmers at the
wildlife-agriculture interface

Mitigation Strategies:
·
In agro-pastural
landscapes, Human Animal Conflict needs to be converted into Human Animal
Co-Existence.
·
Maintaining
the delicate balance between Wildlife Protection Acts and Crop Protection
modules for Vertebrate Pest Management (VPM).
·
Development
of location species VPM practices duly attaching practicable timelines for
withdrawal mechanism.
·
Creating
safe zones for Wildlife as an integral part of agro-pastoral landscapes.
·
Evolving
synchronization between wildlife biologists and plant protection specialists for
a win-win strategy.
·
Creation of buffer zones in the cropped areas,
duly working out economic modalities based on agro-ecological zones of India.
The
traditional strategies to manage such situations include fires, banging metals,
and fencing. These are the widely used mitigation strategies to combat this
issue.
AI as a Wildlife-Human Conflict Solution:
A scalable solution
to this challenge requires a low-cost technology to detect wild animals
especially elephants and transmit alerts to wildlife managers and communities
to prevent conflict situations before they occur. Using new advances in
artificial intelligence technology, RESOLVE’s camera system, called WildEyes
AI, now enters the field. The small cameras work remotely, hidden in a
tree above the reach of elephants, and when the camera’s motion sensor is
triggered, it uses computer vision to detect elephants in the frame and
transmits those images in near-real time to the cell phones of village
guardians.
Conclusion
Global
Food Security Challenge is one the biggest challenge human society facing
today, the cause discussed above results into both economic loss and food yield
loss to a greater extent. There is an urgent need to address this issue globally
as a priority as it is impacting crop fields, farmers live along with global
biodiversity population. To combat this challenge, we need to use our land
sustainable and it is estimated that to satisfy the global hunger we require 30%
of the habitable land but we are encroaching more and more wild land resulting
into disturbances among the wild animals. Sustainable land-use and AI as a
technology to monitor and management this issue will help in reducing the
Human-Wildlife Conflicts Globally.
