GPS study aims to reduce human-animal conflicts in Assam

Why in the News

Assam has moved from a major knowledge gap on where its wild elephants go to a five-year satellite-tracked map of how they move through forests, tea plantations, farmland and riverine habitats. The Assam Forest Department and World Wide Fund for Nature-India (WWF-India) released the study during the 72nd Wildlife Week to guide habitat protection and reduce human-elephant conflict.

What did the tracking study do?

1. GPS satellite tracking: Collars fitted on wild elephants record their position through the Global Positioning System (GPS), much like a phone sharing its live location. Researchers then map where and when the animals move.
2. Who was tracked: Four female-led herds and a solitary male were followed in Udalguri, Sonitpur and Biswanath, three high-conflict districts on the northern bank of the Brahmaputra.
3. Scale of data: Over five years, tracking generated more than 38,000 GPS locations across multi-use landscapes, areas shared by forests, farms and plantations.
4. The report: The findings appear in ‘Tracking the Giants: Movement and Habitat-Use Patterns of GPS-Collared Elephants in Assam’.
5. The takeaway: Assam now has baseline information on where elephant ranging overlaps human land use, the exact zone where conflict arises, so prevention can be targeted there.

What did the elephants’ movements reveal?

1. Core habitats: Sonai-Rupai, Behali and Bornadi Wildlife Sanctuaries were used extensively. Protected areas and reserve forests stayed important elephant habitat for much of the year.
2. Tea plantations as pathways: Elephants used tea plantations as movement pathways and secondary habitats, places to pass through and stay outside forests, which often brought them close to people.
3. Paddy season expansion: Herds showed a strong seasonal pattern. The home ranges of female-led herds expanded during the paddy cropping season, a period of high human-elephant conflict.

Why does Assam need this map?

1. Conflict toll: Human-elephant conflict has killed 1,147 people and 246 elephants in Assam over the past decade, the State’s Forest Minister told the Assembly.
2. Elephant stronghold: The 2025 Synchronised All India Elephant Census found Assam to be the northeast’s stronghold of Asian elephants, with about 4,149 animals.
3. Planning uses: The Minister said the study will guide conservation planning, wildlife-friendly infrastructure and safer coexistence between people and wildlife.
4. What conflict management needs: WWF-India’s elephant programme said preventing conflict requires knowing where elephants move, which habitats and land they use, and how this shifts across seasons.

Challenges

1. Small sample: Five tracked groups in three districts cannot capture elephant behaviour across the whole State.
2. Working landscapes: Tea estates double as elephant pathways and workplaces, so daily contact between people and elephants is built into the landscape.
3. Crop losses and retaliation: Herds range widest when paddy is in the field, and crop losses push farmers towards illegal electric fencing and poisoning.
4. Data to action gap: A movement map changes nothing on the ground until it shapes fences, roads and land-use decisions.

Way Forward

1. Secure mapped pathways: Protect the sanctuary and tea-garden routes the study mapped, treating them as elephant corridors.
2. Seasonal early warning: Use tracking data to send alerts to villages near herd routes during the paddy season.
3. Wildlife-sensitive development: Fold movement data into road, rail and zoning decisions before projects are approved.
4. Faster compensation: Pay crop and life losses quickly and transparently through direct benefit transfer, so tolerance for elephants does not erode.

Conclusion

Assam now knows where its elephants go and when, which lets conflict management move from reacting to raids to planning for them. The test is whether the State turns these maps into protected pathways and seasonal warnings before the next paddy season.

Back2Basics: Asian elephant

1. Conservation status: Endangered on the International Union for Conservation of Nature (IUCN) Red List, and listed in Appendix I of the Convention on Migratory Species (CMS).
2. India’s share: India holds the largest wild Asian elephant population, about 60% of the global total by the 2017 census.
3. Range States: Karnataka has the highest population, followed by Assam and Kerala.
4. Project Elephant (1992): The central scheme protects elephant habitats and corridors, to reduce crop damage and accidental deaths.
