Silent Valley – Millennial Matriarchs

Madhav Dhananjaya Gadgil (24 May 1942 – 7 January 2026) was a towering figure in Indian ecology — a scientist, policy-maker, mentor, and grassroots environmentalist whose work reshaped how India understands the links between nature, people, and development. Often called a “people’s scientist,” Gadgil blended rigorous ecological science with deep respect for local communities, popular movements, and democratic participation in environmental conservation.

Silent Valley: India’s First Environmental Movement

Gadgil played a key role in one of the defining moments in India’s environmental history–the Save the Silent Valley Movement in Kerala during the late 1970s and early ‘80s. The state government had proposed a hydroelectric dam project that would have submerged a pristine stretch of rainforest in the Western Ghats, home to unique biodiversity. Local communities, scientists, poets, students, and activists mobilized against the project, marking one of India’s earliest and most influential environmental movements.

While many voices led by the Kerala Sastra Sahitya Parishad (KSSP) contributed to the struggle, Madhav Gadgil’s role was pivotal. His ecological research, field surveys, and clear articulation of Silent Valley’s extraordinary biodiversity helped transform localized protest into a nationwide call to protect forests and biodiversity.

He was a member of the high-level committee set up by the Government of India to take a call on this issue. The multidisciplinary committee was chaired by Prof. M. G. K. Menon, former Secretary to the Government of India. Gadgil served as a member of this expert committee, contributing ecological assessments that highlighted the valley’s irreplaceable biodiversity and the risks of irreversible ecological loss. His scientific input helped strengthen the case against the dam and gave credibility to what was, at the time, an unprecedented challenge to state-led development.

Equally significant was Gadgil’s engagement beyond formal committees. He worked closely with activists and civil society groups, translating complex ecological arguments into accessible language. Silent Valley demonstrated that science could empower people, and that environmental decisions could be contested democratically. The eventual shelving of the project and the declaration of Silent Valley as a National Park marked a watershed — proving that ecological reasoning and public mobilisation could alter national policy.

The success at Silent Valley is widely considered India’s first major environmental movement, catalyzing grassroots activism and inspiring future campaigns from the Narmada Bachao Andolan to forest rights movements across the country. Gadgil’s engagement with activists and communities during this period helped to define the approach for the environmental movement in India — one that bridged science, social justice, and grassroots mobilization.

Early Life and Academic Foundations

Born in Pune to economist Dhananjay Ramchandra Gadgil, Madhav Gadgil grew up with a curiosity for nature that would shape his life’s work. After earning his Ph.D. from Harvard University, he returned to India and joined the Indian Institute of Science (IISc), Bengaluru, where he founded the Centre for Ecological Sciences in 1983 — one of the country’s first research institutions dedicated to ecology, conservation biology, and human ecology. He helped usher in quantitative and rigorous ecological research in India, while challenging scientists to see humans as part of ecosystems, not apart from them. He has over 250 scientific papers and several influential books.

Championing Community-Centric Conservation

Long before “community participation” became a buzzword in environmental policy, Gadgil argued that local people must be placed at the center of conservation efforts. He believed that traditional and indigenous ecological knowledge — from sacred groves to tribal land management — holds the keys to sustainable stewardship of ecosystems.

Western Ghats and the Gadgil Commission

Gadgil’s commitment to community-centric conservation reached a new peak in 2010 when the Government of India appointed him chair of the Western Ghats Ecology Expert Panel (WGEEP) — later known as the Gadgil Commission. The panel’s 2011 report recommended that nearly 64 % of the Western Ghats — one of the planet’s most significant biodiversity hotspots — be designated as ecologically sensitive areas (ESAs), with varying restrictions on development activities. It emphasised not only environmental safeguards but also community empowerment and sustainable livelihoods.

Although the report was met with political resistance in several states and its recommendations were later diluted, its bold scientific and ethical vision sparked intense public debate and ongoing legal and civic activism. Subsequent environmental crises, including major floods in Kerala and Karnataka, vindicated many of the panel’s warnings about unchecked development and ecosystem fragility.

Policy Influence and National Legacies

Gadgil helped shape India’s environmental legal framework. He was one of the key architects of the Biological Diversity Act (2002), which created mechanisms like People’s Biodiversity Registers to document and safeguard local biological knowledge. He also contributed to implementation of the Forest Rights Act, strengthening community claims over traditional lands. His advisory roles included membership on the Scientific Advisory Council to the Prime Minister and various national conservation bodies.

Honours and Recognition

Gadgil’s work garnered some of the highest honours in science and conservation, including the Padma Shri (1981), Padma Bhushan (2006), the Tyler Prize for Environmental Achievement, the Volvo Environment Prize, and the UNEP’s Champion of the Earth award in 2024 — the United Nations’ top environmental accolade.

In an age where climate, biodiversity loss, and development pressures intensify, Gadgil’s ethos — that science must serve society and empower its most vulnerable — continues to inspire generations of environmentalists, scholars, policymakers, and citizens alike.

We are blessed to have had such a dedicated eco-warrior, teacher and scientist.

RIP Madhav Gadgil

Last week, we paid our tribute to Prof. MK Prasad—one of the key people behind saving Silent Valley. This week, I thought I would re-visit some details about Silent Valley and the campaign.

The Silent Valley deep in the Western Ghats of Kerala is a very special forest. In fact, it is one of the oldest stretches of rainforest in the world, ‘the last authentic sizeable evergreen forests left’, in the words of MK Krishnan, the eminent naturalist.

It is home to about a 1000 species of flowering plants, 107 species of orchids, 100 ferns, 200 liverworts, 75 lichens and about 200 algae, many of them endemic to the area. It counts 34 species of mammals, 292 species of birds, 31 species of reptiles, 22 species of amphibians, 13 of fishes, 500 of butterflies and moths, besides a multitude of other orders of animal life (keralatravels.com). And these are only the species documented! The valley’s flagship species is the lion-tailed macaque, a species endemic to the Western Ghats.

Many are the myths and legends associated with this forest. It is said that the Pandavas, during their peregrinations after they lost their kingdom to the Kauravas, happened to come to this forest. So enchanted were they that they decided to make it their temporary home. The river that runs through the forest is called Kuntipuzha, in memory of their mother, and the forest itself was called Sairandhari, this being another name for Draupadi.

In 1847, the Englishman Robert Wright came upon the thick forest. He or his colleagues named it Silent Valley. There are several theories about why this name was given. It could of course be an Anglicization of Sairandhari, the traditional name. Or it could be because there are no cicadas in this forest. The constant hum in most forests is due to cicadas, and the absence of this noise can be quite stark. Cicadas do not thrive in wet climate, and that is why they are not common here. Yet another theory is that the British gave it this name due to the presence of the rare lion-tailed macaque whose Latin name is Macaca silenus. But in spite of its name, the Silent Valley resounds to the cadences of the river, bird-calls, monkey-whoops, and insect chirrups.

Silent Valley burst into the national consciousness in the 1970s, when the Kerala Government proposed to construct a dam on River Kuntiphuzha, to generate electricity for the State’s growing needs. When scientists and environmentalists came to know about this, they were very concerned, as it would mean that the Silent Valley would be flooded, and that would be the end of that very special habitat and the unique flora and fauna there.

Kerala Sastra Sahitya Parshat (KSSP), a people’s science movement, took up the cause. On the one hand they did techno-economic and socio-political studies to show the impact of the project, and its pros and cons. On the other hand, they mobilized public opinion, and garnered the support of eminent scientists and people. They also came up with alternatives to building the dam e.g., building a series of small dams, rather than one large one.

It was a long and hard battle. It became a bitter war between the State which wanted the project, and the people who did not. The Centre through the course of the controversy saw many changes, and some of the PMs were for and others against the project. Each set up Committees of scientists. Media was also ranged on the two sides, beginning with local media predominantly in favour of the project, and then slowly veering against it. For a long time, national media paid little attention to the issue, but later weighed in favour of the environment. International environmental organizations also came into the fray. The matter went to court to—with the High Court at some stage giving the go-ahead.

It was when Mrs. Indira Gandhi came back as PM that it began to look as if the conservation movement would win. In 1981, she declared Silent Valley a protected area. But it was found that the hydroelectric dam was not covered in the area under protection. Protests began anew, till finally the project was scrapped in 1983. In 1984, Mrs. Gandhi declared it a National Park—the highest level of protection that can be given. And Silent Valley was saved!

Kerala government has recently decided to declare the buffer zone of Silent Valley National Park as a wildlife sanctuary—the Bhavani Wildlife Sanctuary spread across 148 square km. So hopefully, Silent Valley continues to remain safe!

Hats off to the scientists, environmentalists, poets, artists, students, NGOs , media, politicians and the common people who fought the long and hard battle to preserve our common heritage.

There are other such success stories, but sadly not very many. And even more sadly, hardly any in recent times.
