Chilka Bachao Andolan: Saving Asia’s Largest Natural Lake

Chilka Lake, a vast brackish-water lagoon on the Odisha coast, is one of the most ecologically rich water bodies on the continent. In the early 1990s, this lagoon became the centre of a fierce struggle between local fisher communities and a powerful industrial-government partnership that wanted to convert its waters into a commercial prawn farm. The result was the Chilka Bachao Andolan, a people’s movement that not only halted a major project but also raised hard questions about who development is really meant to serve. This is the story of that movement, why it mattered, and what it teaches us about environmental and social justice.

Why Chilka Lake matters 🔗

Chilka (also spelt Chilika) is a shallow lagoon spread across the districts of Puri, Khurda and Ganjam in Odisha. It is connected to the Bay of Bengal by a narrow channel, which gives it a unique mix of fresh, brackish and marine water. This blend makes it an estuarine ecosystem and a biodiversity hotspot that shelters endangered species, including the Irrawaddy dolphin. It is also the wintering ground for more than a million migratory birds each year.

The lagoon’s importance was recognised internationally very early. It was designated as the country’s first Ramsar Site, a wetland of international importance, on 1 October 1981. Beyond its ecological value, Chilka is a lifeline. Its rich fishing grounds sustain the livelihoods of more than 1.5 lakh fisher-folk who live in and around the lagoon. Any threat to the lake, therefore, is simultaneously a threat to thousands of families whose survival depends on its waters.

The trigger: a prawn farming project 🔗

The conflict began with prawns. Through the 1980s, the lagoon was already under pressure from siltation, encroachment by outsiders, and the spread of commercial prawn culture that disturbed the natural balance of the lake. Matters came to a head when the Government of Orissa signed an agreement for a large aquaculture venture.

The Integrated Shrimp Farm Project 🔗

The project at the centre of the storm was the Integrated Shrimp Farm Project (ISFP), described as a joint venture of the Tata Iron and Steel Company and the state government for intensive prawn cultivation and export. On paper, it promised revenue and growth. In practice, it posed a direct threat to the fishing communities living around the lake.

The way the land was acquired also drew sharp criticism. Before the allotment, the land was not classified as property that could be leased; at the time of allotment, it was reclassified as community pastureland, and the project began without a proper Environment Impact Assessment. To critics, this signalled that the rules were being bent to favour a commercial enterprise over the people who already depended on the resource.

Environmental and livelihood threats 🔗

The objections were rooted in concrete harms. Intensive shrimp farming changes the salinity of the water and damages the natural habitat, threatening the fish species that traditional fishermen rely on. The lagoon was also struggling with siltation caused by deforestation in its catchment, which reduced its depth and choked the channel connecting it to the sea. As the fish catch fell, the income and way of life of the fishing communities were placed in serious danger. The damage was not only ecological but also social and economic, falling hardest on the poorest groups.

How the movement took shape 🔗

The Chilka Bachao Andolan did not appear overnight. It grew step by step as different groups recognised a shared threat and decided to act together.

From student concern to organised resistance 🔗

An early organisational push came in 1991 with the formation of the Chilka Suraksha Parishad, a forum created to gather public opinion and open up debate on the state’s prawn project. Students realised that local organisations could play a decisive role, and they reached out to the Chilka Matsyajibi Mahasangha, a federation representing 122 revenue villages working to protect fishermen’s interests. In 1992, the Chilka Bachao Andolan emerged as an extension of this federation, gradually drawing in civil society organisations.

A broad coalition 🔗

What gave the movement its strength was its breadth. The fishermen were at the core, but they were joined by farmers, students, intellectuals, human rights activists and environmentalists. Student leaders such as Chittaranjan Sarangi organised a padayatra through the villages along the lake, while former state finance minister Banka Behary Das became actively involved, organising a series of conferences that built into a state-level convention. The agitation grew so widely that it took on an all-India character, with letters of support arriving from across the country.

Strategies and pressure points 🔗

The movement used a mix of methods that combined grassroots mobilisation with public debate. Padayatras carried the message directly into the villages, conferences and conventions built a unified demand, and the involvement of intellectuals and the media amplified the issue far beyond Odisha. Crucially, the campaign focused on the lack of a proper environmental review, pushing the state government to assess the environmental impact of the project and demanding that the lake be recognised as an endangered wetland.

This combination of moral, legal and political pressure made it difficult for the authorities to dismiss the protest as the complaint of a small group. Even members of the ruling establishment began to voice support, and some company directors reportedly expressed misgivings about going ahead.

What the movement achieved 🔗

The most direct outcome was the abandonment of the shrimp farming project. The sustained pressure from the coalition forced the project to be shelved, protecting the lagoon from intensive commercial aquaculture.

The campaign also coincided with serious official attention to the lake’s declining health. The lagoon was added to the Montreux Record, the list of threatened Ramsar wetlands, in 1993, signalling the gravity of its ecological crisis. The Chilika Development Authority was set up in 1992 to lead restoration, and after major interventions, the lake was removed from the Montreux Record in 2002 as its ecosystem recovered. The restoration is now cited as one of the boldest conservation efforts in the country’s history.

The bigger question: whose development? 🔗

It is worth noting that the movement was not only about opposing one company. Observers point out that the main focus was the larger question of how a vulnerable area’s resources should be used and controlled. The protesters challenged a model of development that treats natural resources mainly as inputs for commercial profit while ignoring the sustainable, subsistence use that supports local communities.

This is why the Chilka Bachao Andolan is studied alongside the Chipko movement and the Narmada Bachao Andolan as one of the prominent ecological movements of independent India. The struggle raised governance questions about how policies are made, who decides how shared resources are used, and how socio-economic equity is balanced against the push for industrial growth. A case study prepared for a programme on rights, justice and development records the movement as a successful instance of people resisting an exploitative project.

Why it still matters today 🔗

The lessons of Chilka remain relevant. Coastal ecosystems across the country continue to face pressure from aquaculture, infrastructure and pollution. The Andolan showed that environmental protection and livelihood security are not separate goals but two sides of the same coin. It also demonstrated that organised, broad-based local action can hold both the state and large corporations accountable, especially when projects bypass proper environmental safeguards.

What do you think? Should large-scale commercial projects ever be allowed in an ecologically sensitive wetland if local communities oppose them, and how would you decide where to draw the line? When development and conservation collide, whose voice should carry the most weight in the final decision?
