Mapping connectivity and human-elephant conflict in Karnataka

Fencing is a key conflict mitigation strategy in the Mysore Elephant
Reserve in Karnataka, which sees regular cases of human-elephant conflict.
Putting up fencing accounts for a significant proportion of the
government’s spending. Researchers in a recent study, however, find that
the fences along the northern boundaries of Nagarhole–Bandipur National
Parks, two contiguous protected areas that support key elephant populations
in the elephant reserve landscape, may mitigate conflict but at the cost of
connectivity.

The study addresses human-elephant conflict in the elephant reserve through
a modelling technique where conflict mitigation and connectivity are looked
at together rather than in isolation. The study maps such
conflict-connectivity areas and suggests a broad-scale conservation
management plan which could be implemented in areas where humans share
these landscapes with elephants.

Additionally, to address the conflict, they emphasise that the move to
capture and remove 22 elephants from the Alur-Sakleshpur area of the
landscape in 2014 because the area was considered to house an isolated
elephant population is “misdirected.”

The area was recolonised by elephants within a year of the elephants’
removal. “Our results predict high movement through the area and provide a
scientific basis for the expected and observed (post 2014) recolonisation
of the area to make a case against reactive removal of elephants from
fragmented habitats,” said study author Varun Goswami, senior scientist and
director, Conservation Initiatives, a not-for-profit based in northeast
India.

“Connectivity and conflict are interdependent; where conflict is high or
low depends on connectivity. If an elephant is coming out of a park and
sees humans or fences, its movement path will get modified. So conflict
itself can modify connectivity. Both these aspects are modelled together in
this study, and we see where they clash,” says Divya Vasudev, joint
director and senior scientist, Conservation Initiatives, and lead author of
this paper.

Mapping Movement Choices
While mapping animal movement, Vasudev says one needs to understand where
the animal has moved, why the animal is making certain decisions and how
far has the animal gone?

In India, for instance, if an elephant encounters a plantation versus a
crop field, which path will the animal potentially take?

Robert Fletcher, professor, at the Wildlife Ecology and Conservation
Department, University of Florida and co-author of the paper says the model
uses information on how animals use habitats to predict their movements
across landscapes.

“This is a new model that is beginning to be applied throughout the world.
Along with elephants, we are currently using it to identify the best places
to reintroduce predators (grey wolves in Colorado) to minimise problems, to
identify where invasive species may spread to guide management
interventions (Burmese pythons in Florida), and other examples for corridor
identification.”

In Mysore Elephant Reserve, the researchers surveyed 9100 people,
interacted with farmers, asking them if they had seen elephants, and if
there was a conflict. The interviews, along with media reports on crop
raids were considered, and this data was validated with the model.

Suggested Measures
Varun Goswami, explains that there can be four types of locations in any
conservation landscape: areas with low conflict, high movement; areas with
low conflict, low movement; areas with high conflict, low movement; and
areas with both high conflict and high movement.

“We have created a map for the Mysore Elephant Reserve that shows all of
these different areas. We have also provided suggestions on optimal
conservation strategies for each type of location. This insight, we hope,
will help wildlife managers and conservationists to plan for human-elephant
coexistence in the landscape.”

According to him, the most difficult space is the connectivity-conflict
interface. Connectivity is important for elephant populations, but conflict
mitigation is also a priority. Areas where there is high conflict,
mitigation should happen through strategies that do not obstruct
connectivity.

For instance, instead of fencing elephants into forested areas, the idea
would be to fence them out of sensitive human areas, like human
settlements, or vulnerable crop growing areas. Negative human interactions
with elephants can be averted this way while elephant movement through the
landscape can continue.

There is a need for fine-scale information, says Vasudev.

She says, “There are other factors that affect connectivity like linear
infrastructure. For instance, if a road is going to appear in the
connectivity area, we have to plan for mitigation accordingly.”

Vasudev suggests that secure corridors should be maintained as they are,
because land use preservation is critical. Secure corridors, here, are not
restricted to forested corridors, but include lands like plantations. This
could allow movement of elephants and also serve livelihood needs of people.

Policy can incentivise connectivity-friendly land use practices (e.g.,
crops that are not eaten by elephants). “Such maps can also be included in
the management plans of individual protected areas and the elephant
reserve. Systematic monitoring should be done to assess if conflict
mitigation measures and connectivity conservation measures are successful.
For all of this, it is important that stakeholders work together.”

B. Ramakrishnan, professor, department of wildlife biology, Government Arts
College, Udhagamandalam, also a member of IUCN Asian Elephant Specialists
Group, emphasised the need to look at elephant conflict history, including
land use pattern, habitat fragmentation, etc. as conflicts have been going
on for a long time, and it is necessary to understand those changes.

The core of this conflict is habitat fragmentation. Vasudev says, “Every
time there is a conflict incident, we talk about fragmentation. It is
critical to hit the pause button on fragmentation.”

Ramakrishnan concurs. “Elephants are large animals, needing larger foraging
space. Pocketing them into small habitats is not good. As habitats are
shrinking, the vegetation and foraging area is also reduced. As a result,
food availability is limited for these animals. Further, there are other
animals in the space competing for the resource.”

“The elephants get lured by the crops if they are between two protected
areas,” says a Karnataka forest department official.

“Farming systems have changed from seasonal to perennial cropping with
borewells. The farmers are not willing to shift crops as they make profits;
it’s their livelihood,” says Ramakrishnan.

Lack of Tolerance
“The only solution for human-animal conflict is co-existence, but there is
no tolerance. When an elephant is in a human habitat, and where there were
two-three deaths, we have to tackle that problem immediately. Negotiating
with the farmers, sitting at panchayat meetings are not helping. When death
arises from conflict, people will not be in a position to listen to us,”
says a senior Karnataka forest department official.

There is an elephant task force in place to deal with this issue. Every
time a conflict happens, the forest department addresses the issue on
ground. Over the years, the department has improved their mechanisms,
including fences and trenches, but elephants find ways to get past these
barriers.

“Whatever we do, the conflicts are increasing every day,” says the official
who requested anonymity.

The forest department has set up water holes for elephants, they are
removing Lantana camara (an invasive alien plant species) and digging
trenches around the parks. Other than this, there is an early warning
system and SMS alert. When collared elephants are in a particular area,
push messages go to the village residents, warning them not to venture out.

In conflict mitigation, the forest department spends on ex-gratia
(compensation) and fencing. This expenditure has doubled in the Karnataka
forest department.

The official says, “Where elephant proofing is there, the problem is
reduced largely. The elephant deaths from crossing the barricade is
minimal. Not all elephants will not cross the fence, the tall ones over
three metres height will; those with a height of 2 or 2.5 metre height will
not. Such cases are also negligible.”

“Whatever we do, the conflicts are increasing every day,” says the official.

For conflict mitigation, the forest department spends on ex-gratia
(compensation) and fencing. This expenditure has doubled in the Karnataka
forest department.

Where a compensation of Rs. 7.5 lakhs were given earlier for human deaths,
now, the amount has doubled to Rs. 15 lakhs. Compensations have doubled for
crop damage. For instance, from Rs. 1320 for a quintal of paddy, it is now
Rs. 2640. These numbers vary across crops.

“In the Karnataka forest department, ex-gratia payments are app-based.
Details of farmers are gathered, photos are taken, the affected crop area
is calculated, and the compensation amount is generated and transferred
directly to their bank accounts after the District Forest Officer’s
approval. Date, phone numbers are included, making this a transparent and
fool proof mechanism that cannot be tampered even by the forest
department,” the official said.

Along with this, some family members are given temporary jobs (for
instance, drivers or watchers). Over the years, the forest department has
increased the human resource, with systematically organised teams. They are
disbursing higher budgets for conflict resolution. The department also
spends on maintenance of trenches.

“A lot of research happens, but how many researchers share their published
papers with the department or discuss solutions? Very few of them approach
us,” says the official.

Ramakrishnan concurs, “We need to engage in long term studies, and also
discuss such research outcomes with the forest department for policy
making.”

According to Ramakrishnan, conflict-connectivity mapping will be good, as
long as these areas are monitored for a minimum of 3-5 years. He says,
“Only then we can assess the impact. Further, for conflict, there is a need
to look at long term behaviour of the animals, change in land use, cropping
pattern, habitat fragmentation among others.”
