A sloth bear searching for food is not always able to distinguish the boundary between the forest and the settlement. If food is scarce inside the forest, but easily found near the settlement, the animal will follow the source of food. An open dump filled with food waste can offer an easy meal. If the bear finds food there repeatedly, it may start returning to that place. Thus, hunting, which began as a search for sustenance, can lead the animal into closer contact with humans.
Therefore, when a sloth bear is found on the road or near a settlement, the question arises not only about the reasons for its appearance but also about what has changed in the surrounding landscape. Dr. Harendra Singh Bargali, Deputy Director and Head of Conservation, Policy, and Advocacy at the Corbett Foundation, has dedicated more than two decades to studying sloth bears and wildlife interaction with humans. His research provides some answers.
The scientist who studied bears for years
Dr. Bargali began working with sloth bears in 1998 when he joined a long-term study funded by the Indian Wildlife Institute as a research fellow. The project included radio collars to study the movement, activity, and ecology of sloth bears. According to him, the answer in Nilgiris lies in the state of the bears' habitat.
When forests are fragmented, bears have less space to move. Sloth bears are not confined to one small forest zone. Dr. Bargali notes that historically, according to the natural behavior of the species, they explored territories around their main habitats. If there were fruitful trees, honey, or edible crops available at the edges of the forests, the bears would go out to feed. Such behavior itself is not new.
However, the surrounding landscape has changed. Cities and settlements have expanded, roads and other infrastructure have appeared. Forest areas have been converted for activities such as commercial tea plantations. This has led to greater fragmentation of sloth bear habitat and increased their contact with humans. In Nilgiris, these changes, along with the depletion of natural resources, have affected sloth bear populations and increased the likelihood of encounters with local communities.
He tells The Better India that when natural resources become scarce, sloth bears are likely to explore all available options to meet their nutritional needs and ensure survival. These options may include agricultural fields, plantations, and settlements, and sometimes piles of household waste.
A garbage dump can become an easy food source
Food waste is particularly attractive when finding natural food becomes difficult. Dr. Bargali asserts that when bears face a shortage of natural resources in their habitats, the availability of dumps and trash bins can attract them to areas dominated by human activity.
Once a bear finds food in a specific location, the problem can worsen. He points out that older individuals and cubs may also start visiting such places after repeated contact. Social learning also plays a role here. According to him, if access to anthropogenic food becomes a regular part of their diet, they may become increasingly dependent on these sources. This means that when food is no longer available at the dump, the bear may search further, moving towards nearby homes and other places where food can be found. This is why the waste problem cannot be considered separately from bear encounters.
Nevertheless, simply removing trash will not solve all problems.
Why one cleanup action will not solve the problem
Improved waste management can eliminate one of the reasons why bears intrude into human spaces. In areas near bear habitats, the expert recommends using bear-proof containers, properly sorting waste, and completely stopping open dumping. However, there is a broader question: what happens if a bear leaves the dump but still cannot find enough food in the forest?
He emphasizes that it is equally important to understand the requirements of sloth bears for their habitat and to assess the presence and seasonal distribution of natural resources in their fragmented habitats. If these resources remain limited, bears may continue to move towards gardens, fields, orchards, and other places where there is food. This is why the conservation biologist believes that Nilgiris needs both improved waste management and a deeper study of what is happening within the remaining sloth bear habitats.
Crowds around a bear can worsen the situation
The appearance of a bear in a city can frighten people and attract crowds, which can make the situation dangerous. Dr. Bargali says that bears that are chased, surrounded, or stoned may try to run in any direction. If people block this escape route, someone could get in the animal's path.
He notes that sloth bears generally do not pursue humans with the intention of attacking. However, when they are chased, cornered, or threatened, they may respond defensively. This makes the reaction of people upon spotting a bear extremely important. The conservationist studied 138 cases of sloth bear attacks and interviewed involved people to understand the course of these encounters. His advice is simple:
- If the bear is at a safe distance, remain calm and slowly back away.
- Do not shout or make sudden movements.
- Do not chase, surround, or throw stones at the bear.
- Ensure it has a clear path to retreat.
- Inform nearby people and contact trained forest personnel.
- Do not try to handle the situation yourself.
Close encounters are especially risky at turns and blind spots where a person and a bear might suddenly come face-to-face. A frightened bear may stand on its hind legs and use its forelimbs for self-defense. Its long curved claws can inflict serious injuries at close range, especially to the head and face. At the same time, the bear specialist notes that his observations did not show bears pursuing people after an encounter to continue the attack. In the cases he studied, the bear usually attacked and left.
What needs to change in Nilgiris? There is no single group that can solve this problem. According to The Hindu, a meeting was recently held in Nilgiris to discuss ways to limit human-sloth bear interaction, highlighting the need for communities and authorities to understand how to react when bears intrude into human-controlled areas. Households and communities need information about sloth bear behavior and what to do during an encounter. Hotels and restaurants, especially those located near bear habitats, must store food waste in secure containers and prevent wild animals from accessing it. Local authorities must have systems for regular collection, sorting, transportation, and safe disposal of waste, as well as checks to prevent open dumping. Tourism and forest departments must also cooperate, especially in tourist areas near sloth bear habitats. The forest department also needs better information about the bears living in Nilgiris. Dr. Bargali believes that studies should cover their population, movements, habitat needs, and seasonal availability of natural resources. They should also study places where bears are closest to humans and why. This information can help authorities identify areas where encounters are more likely and plan measures before the problem becomes serious.
Does every bear entering a settlement need to be captured? Not necessarily. A bear appearing in a settlement does not automatically mean something is wrong with the animal. The conservationist says that a random visit to a fruit shop or a house with hives may be related to searching for food. However, repeated or persistent attempts to enter homes, especially when the bear seems unable or unwilling to leave, require immediate attention. In such cases, the forest department should be notified. Trained wildlife veterinarians and experienced forest staff can assess the animal's physical condition and behavior before making a decision on further action. In the long term, he points to protecting remaining habitats, preserving the integrity of ecological corridors, improving degraded areas, and restricting access to human food.
The answer is not just a cleaner dump
For the residents of Nilgiris, avoiding an encounter with a sloth bear can start with a routine action like ensuring that food waste is not left in places accessible to wildlife. But this is only part of the work. Bears also need forests where they can find food, move between habitats, and live without intruding into human spaces. Dr. Bargali concludes that conservation must focus on maintaining functional and connected ecosystems, not on isolated protection of individual species. For Nilgiris, this means looking beyond the next bear sighting and asking what is happening with the surrounding landscape. Improved waste management can eliminate one reason for the bear's visit to the settlement, while habitat protection and understanding available food can solve another. Dr. Bargali argues that coexistence will require communities to understand bear behavior, local authorities to stop open dumping, and the forest department to properly study the species and its habitat. This will take time. He concludes with the words: 'There is no shortcut to achieving long-term coexistence.' The goal is not to force wild animals to behave as if they belong in the city, but to reduce the reasons they intrude into it in the first place.
