Syllabus Link: GS III – Wildlife conservation, habitat fragmentation and human–wildlife conflict

Why in the News?

A GPS telemetry study has highlighted how Asian elephants in Assam depend on a landscape extending beyond protected forests, including tea estates, agricultural fields, riverine grasslands and human settlements. The findings underline the need for landscape-wide conservation to protect elephants while reducing risks to local communities.

Key Findings

• Extensive movement: Some elephant herds have annual home ranges exceeding 500 square kilometres, with one recorded range reaching 890 square kilometres.
• Tea plantations as secondary habitats: All four GPS-collared female elephants and their herds used tea plantations in Sonitpur and Udalguri districts for movement, foraging and shelter.
• Human and elephant casualties: Between 2000 and 2023, reported human–elephant encounters in Assam resulted in 1,468 human deaths and 337 injuries. During the same period, 626 elephants died from human-induced causes, including electrocution, poisoning and train collisions.
• Habitat fragmentation: Historical deforestation, agricultural expansion, settlements and infrastructure development have reduced and fragmented traditional elephant habitats.

Why Is Human–Elephant Conflict Increasing?

As forests shrink, elephants increasingly enter farms and tea estates, where crops such as paddy, maize, banana and sugarcane provide food. This increases crop losses and the likelihood of dangerous encounters.

Electric fences and exposed power lines, railway tracks and roads can further threaten elephant survival. Protecting isolated forest areas alone cannot address these risks because elephants move across administrative and land-use boundaries.

Conservation Measures and the Way Forward

• Protect wildlife corridors: Critical routes such as the Nameri–Sonai Rupai–Arimora corridor and riverine movement channels need protection from unplanned development.
• Prevent electrocution: Forest-range-level anti-electrocution teams and regular monitoring of vulnerable power infrastructure can reduce avoidable deaths.
• Make infrastructure wildlife-friendly: Suitable underpasses, overpasses and early-warning systems along vulnerable highways and railway sections can reduce collisions.
• Restore habitats: Scientific assessment of habitat quality can identify degraded areas requiring restoration.
• Promote coexistence: Forest departments, tea estates, farmers, railway authorities and local communities must coordinate land-use planning and conflict prevention.

Relevant Framework

Project Elephant, launched in 1992 by the Government of India, supports elephant conservation, habitat and corridor protection, and measures to reduce human–elephant conflict.

Exam Hook: Key Takeaway

Elephant conservation requires a landscape-level approach that protects movement corridors and reduces risks across forests, tea estates, farms and infrastructure networks.

Mains Question

Discuss the causes of human–elephant conflict in Assam and suggest measures for ensuring wildlife conservation alongside community safety.

One-line wrap: Protecting elephants means protecting not only forests, but also the routes through which they move across a changing human landscape.
