Pune, Jan 08, 2026 – Madhav Gadgil, one of India’s most respected ecologists and a pioneering voice for environmental conservation, passed away at the age of 83 after a brief illness in Pune on Wednesday night. His son, Siddartha Gadgil, confirmed the news, stating, “I am very sorry to share the sad news that my father, Madhav Gadgil, passed away late last night in Pune after a brief illness.” Gadgil’s death marks the loss of a scientist whose work spanned six decades and whose contributions shaped both grassroots environmentalism and national policymaking in India.

Gadgil was particularly renowned for his work on the Western Ghats, one of the most ecologically sensitive regions in India, and for his efforts in promoting community-driven conservation practices. He was also named one of six “Champions of the Earth” for 2024 by the United Nations Environment Programme (UNEP), recognizing his lifetime achievements in ecological conservation.

Early Life and Education

Madhav Gadgil was born in 1943 in Pune, Maharashtra, into a family that nurtured his early interest in the natural world. His father, a keen birdwatcher, taught him to recognize birds from pictures even before he learned to read. This early exposure to nature fostered a lifelong fascination with biodiversity and the complex interconnections between ecosystems and human societies.

Gadgil pursued biology at Fergusson College, University of Pune, before completing a master’s degree in zoology from Mumbai University. He further advanced his studies internationally, earning a PhD from Harvard University in the United States, where he deepened his understanding of ecology and environmental systems.

Academic Career and Contributions

Returning to India, Madhav Gadgil embarked on a long and distinguished academic career. He served as a professor at the Indian Institute of Science (IISc), Bengaluru, for over three decades, where he played a pivotal role in establishing the Centre for Ecological Sciences. Under his leadership, the centre became a hub for both basic and applied ecological research, bridging the gap between academic studies and real-world conservation challenges.

Gadgil was known not only for his scientific rigor but also for his innovative approach to research. He collaborated closely with local communities—including tribals, farmers, herders, and fisherfolk—recognizing that conservation efforts would be most effective when they accounted for the knowledge, practices, and livelihoods of those who lived in ecological hotspots. This approach earned him the reputation of a “people’s scientist,” a term highlighted in the UNEP statement recognizing his contributions.

His academic influence extended globally. He served as a visiting professor of Human Biology at Stanford Universityand remained an active mentor for generations of students and researchers in India and abroad. His work exemplified the integration of field research, scientific analysis, and policy engagement, demonstrating that ecology could not be separated from the social and economic contexts in which it operated.

Policy Engagement and National Influence

Madhav Gadgil’s expertise extended beyond academia into national policy. He was a member of the Science Advisory Council to the Prime Minister of India from 1986 to 1990, providing guidance on ecological and environmental issues at the highest levels of government. He also served on the National Advisory Council from 2010 to 2012 and chaired the Western Ghats Ecology Expert Panel from 2010 to 2011.

It was during his tenure as head of the Western Ghats panel that Gadgil authored the landmark Gadgil Report in 2011, which warned of the severe ecological consequences of unplanned development and industrialization in the Western Ghats. The report highlighted the region’s fragile ecosystems, biodiversity hotspots, and the threats posed by large-scale infrastructure projects and climate change. Gadgil’s recommendations, emphasizing community-led conservation and sustainable land-use practices, were prescient, though their implementation has faced delays over the years.

In addition to the Western Ghats work, Gadgil contributed to the drafting of India’s Biological Diversity Act, which provided a legal framework for protecting the nation’s rich biodiversity while ensuring equitable benefits for local communities. His advocacy often balanced scientific evidence with social equity, reflecting his belief that environmental protection and human development are deeply interconnected.

Recognition and Global Impact

Gadgil’s scientific and policy contributions earned him recognition both in India and internationally. In 2024, he was named one of six “Champions of the Earth” by the United Nations Environment Programme, a prestigious honor recognizing leaders who have made transformative contributions to environmental conservation. The UNEP citation noted his commitment to people-centered ecological science, which not only advanced academic understanding but also directly benefited marginalized communities and influenced policymaking at the national level.

Through his work, Gadgil inspired generations of scientists, conservationists, and policymakers. His advocacy for grassroots environmentalism, sustainable development, and ecosystem preservation set benchmarks for ecological research and environmental governance in India. He consistently emphasized that conservation was not merely a scientific endeavor but a moral and social imperative, requiring collaboration between governments, scientists, and local populations.

Personal Life and Legacy

Madhav Gadgil was married to Sulochana Gadgil, a noted monsoon scientist, who passed away in July 2025. Together, they shared a deep commitment to science and environmental stewardship. His family, students, and colleagues remember him as a mentor, guide, and advocate for ecological justice.

Gadgil’s work has left an indelible mark on India’s environmental landscape. Beyond his scientific publications, reports, and policy recommendations, he nurtured a generation of ecologists who continue to work on biodiversity conservation, climate adaptation, and sustainable development. His insistence on community participation and the ethical dimensions of environmental work has influenced how ecological projects are conceived and implemented across the country.

Final Reflections

Madhav Gadgil’s death at 83 marks the passing of a visionary who combined scientific expertise, ethical responsibility, and social consciousness. From his early days in Pune to the halls of Harvard University, the corridors of IISc Bengaluru, and the highest advisory bodies in India, Gadgil remained committed to protecting the natural world while empowering communities dependent on it.

As India and the world face escalating environmental challenges—from climate change to biodiversity loss—Gadgil’s work serves as a guiding light. His emphasis on ecosystem conservation rooted in local knowledge and scientific rigorremains highly relevant today, offering a blueprint for integrating environmental sustainability with human well-being.

Madhav Gadgil’s legacy will endure in the Western Ghats and other ecological landscapes he sought to protect, in the students and researchers he mentored, in the policies he helped shape, and in the global recognition of his vision for a sustainable future. He leaves behind a world better informed about the delicate balance between humans and nature, and a generation inspired to continue his work.

In remembering Madhav Gadgil, one recalls the words of UNEP: a scientist who saw science not as a distant pursuit but as a tool to empower people, communities, and nations to live in harmony with nature. His contributions have fundamentally shaped India’s environmental consciousness and will continue to inspire efforts toward sustainable development and conservation for decades to come.
