The Indian environmental scientist Madhav Dhananjaya Gadgil, known for his transformational work in ecological science and conservation, died in Pune on January 7, 2026, at the age of 83 following a brief illness the family confirmed to us. The death of Gadgil is a major disaster not only to the Indian environmental movement, but also to scientific India more broadly. Gadgil was born in Pune on May 24, 1942, and grew up to become one of the country’s leading champions on biodiversity and ecological balance.
He graduated from India with his training and education, and then went on to do his PhD at Harvard University with a focus on mathematical ecology. Instead of being an academic in an academic world he became a home-based eco researcher and grassroots organiser.
Gadgil is most famous for leading the Western Ghats Ecology Expert Panel (WGEEP)—the Gadgil Commission now rebranded—to assess the vulnerability of the ecology of Western Ghats, one of the planet’s biodiversity hotspots, in 2010. The 2011 panel report called for extensive ecological safeguards, including a designation of about 75 percent of the mountain range as ecologically sensitive to inform development planning and safeguard landscapes, forests and local communities. The recommendations became a lightning rod for vigorous discussion that was later tweaked in policy regimes, but they were fundamentally part of how scientists and policymakers think about sustainable development in the region.
Gadgil did not only create policy; he worked on bridging science and society. He encouraged conservation where people were themselves at the helm and said that for these reasons there should also be local voice, indigenous wisdom and political involvement. His three pronged approach was to have real benefits in legislation, such as India’s Biological Diversity Act, and the founding of the Nilgiri Biosphere Reserve, India’s first biosphere reserve, in 1986.
Gadgil was a recipient of numerous awards to complement his life work, notably the Champions of the Earth Award 2024—the nation’s highest environmental honor (awarded by the United Nations Environment Programme). Colleagues, politicians and environmentalists have come together grieving his death, describing it as a “major setback for India’s green cause” and extolling his legacy as an enduring scientist, a mentor and an advocate for environmental justice.
