Community inclusion: Utilizing tribal helpers and village-level 'Vajra' teams to bridge the gap between forest management and local residents
Economic mitigation: Increasing compensation for conflict incidents to alleviate financial losses for forest-fringe communities
Why in news: Madhya Pradesh CM Mohan Yadav released gharials and turtles into the Kuno River at Kuno National Park as part of conservation and augmentation efforts.
The release included 53 gharials (28 males, 25 females) and 25 three-striped roofed turtles (Batagur dhongoka) into the Kuno River. Simultaneously, nine cheetahs from Botswana were added to the park, bringing the total cheetah population to 48.

Q. Discuss the significance of 'reintroduction' and 'augmentation' strategies in wildlife conservation, using the Kuno National Park cheetah and gharial projects as examples.
Ecological restoration: Balancing the reintroduction of apex predators with the preservation of local aquatic biodiversity.
Habitat suitability: Ensuring the Kuno River ecosystem can sustain the carrying capacity for both gharials and turtles.

Why in news: Karnataka Forest Minister Eshwar Khandre announced a ₹53 crore soft-release centre to mitigate human-elephant conflict by relocating troublesome elephants to Bhadra Wildlife Sanctuary.
The project involves a 20 sq km enclosure within Bhadra Wildlife Sanctuary for capturing and relocating elephants. The initiative includes a phased release into the wild and a proposal for rail barricades to protect human habitats.

Q. Discuss the ecological and socio-economic challenges of human-wildlife conflict in India and evaluate the efficacy of soft-release centres as a mitigation strategy.
Habitat fragmentation: Shrinking forest cover and rising human population increasing encounter frequency
Conservation trade-offs: Balancing elephant migratory corridors with infrastructure development and rail safety
Mitigation efficacy: Soft-release success depends on adequate enclosure size and phased acclimatization protocols
Why in news: The National Green Tribunal (NGT) issued notices to the Centre and Madhya Pradesh government over environmental clearances granted to the Adani Group's coal block in Singrauli.
Environmental activist Ajay Dubey filed two petitions challenging approvals for tree felling and a proposed elephant corridor in Singrauli district. The NGT directed the Ministry of Environment, Forests and Climate Change, the National Board for Wildlife, and the Madhya Pradesh Forest Department to respond.

Why in news: The India Meteorological Department (IMD) issued a forecast predicting above-normal heatwave days across several Indian states between March and May 2026.
The IMD predicts above-normal heatwave days in regions including West Rajasthan, Gujarat, Haryana, Punjab, Maharashtra, Uttar Pradesh, Bihar, Jharkhand, West Bengal, Odisha, Chhattisgarh, Telangana, Andhra Pradesh, and parts of Karnataka and Tamil Nadu. March temperatures are expected to be normal to below normal in most parts of India due to likely normal rainfall following a record low February rainfall.

Why in news: Researchers warned that climate change will cause a net contraction of suitable habitats for the Nilgiri Wood Pigeon (NWP) in the Western Ghats by the end of the century.
The study, published in 'Proceedings of the Indian National Science Academy', used MaxEnt modeling and 9,757 eBird occurrence records to predict habitat suitability. It found that while initial warming might expand the range, continued warming will lead to sharp declines in suitable areas for the species.
