At dawn, when the waters of Dumboor Lake lie still under a pale grey sky, Santo Chakma, 63, nudges his narrow wooden boat into a reservoir that swallowed his childhood.

The lake is a growing attraction for tourists who come here in search of beauty and tranquillity, with dozens of islands scattered across a vast expanse of water. But for Chakma, the lake reflects a past erased.

“Once, these were rice fields. My father and my grandfather cultivated rice,” he says quietly. “But now we catch fish because there is no land.”

Spread across 41 square kilometres in Tripura’s Gomati basin, Dumboor Lake is now known for its 48 small islands and a growing tourism economy. But beneath its surface lies the submerged Raima–Saima valley – once a fertile agricultural landscape that sustained indigenous communities for generations.

That landscape disappeared in 1974, when the Gumti Hydroelectric Dam transformed the Gomati River into a reservoir, displacing thousands of people, mostly from indigenous tribes such as the Chakma, Reang, and Tripuri.

From Farmers to Fishers

In villages like West Gandecherra – a lakeside village – elderly people carry the memories of their old days in their hearts.

“The Gumti (Gomati) River was our lifeline,” recalls Phulorani Tripura, an elderly resident. “We used to sail bamboo rafts.”

Across the region, communities tie bamboo in large bundles and throw them upstream. The river carries the bundles down and people travel on them using these bundles as their rafts. For days, they live on these bamboo rafts, sleeping on them and selling produce from their farms, such as homemade butter and peppers, until they reach a market where the bamboo is sold.

“Water was not our livelihood – it wasn’t our way of living,” Chakma reminisces.

That world collapsed after the dam was built as farmland, homes, and markets were submerged. Families were relocated to uplands, where agriculture proved unreliable. Many eventually returned to the lake – not as traders or farmers, but as fishers.

Today, nearly 5,000 families depend on the lake’s fisheries, navigating livelihoods born out of displacement rather than choice.

An Increasingly Fragile Livelihood

Every morning, lines of small boats move out across Dumboor. By afternoon, they return with their catch, which is often smaller than in previous years. Fish diversity has declined due to overfishing, reduced stocking, and ecological stress.

“Earlier, fish were plentiful. We caught big fish like rahu (Labeo rohita), katla (South Asian carp) and gojal (channa marulius). If we sold one fish weighing 4-5 kg, it would be enough money for a whole week. Now we catch more small fish, which sell for less and also don’t stay fresh for long, which brings even less. So, now we work harder for less,” says Sushil Chakma, a fisherman, untangling his net.

Economic pressures add another layer of strain. Fishing licences cost up to ₹10,000, while government-fixed prices can be lower than 1 dime (US) per kilogram, leaving fishers dependent on middlemen.

“The government charges us, but the benefits don’t reach us,” Chakma says.

There are also constant safety risks due to erratic weather, fluctuating water levels, and fragile bamboo fishing platforms – known locally as ‘mancha’ – which have led to repeated fatalities.

“We call these platforms ‘mancha’, and we often hear that one has broken and fishermen have drowned,” says Bryn Tiprasa, a youth originally from East Gandecherra village near the lake, now living in Agartala, about 120 kilometres away.

“In fact, only last month, a fisherman died like that. Two years ago, four fishermen died in a single incident. Will this project consider addressing these kinds of problems? We don’t know yet.”

Tourism Grows, but Locals Miss Inclusion

Dumboor has increasingly been promoted as a tourism destination, with sites like Coconut Island attracting visitors for boating and festivals.

The Government of India has invested significantly in developing tourism infrastructure around the lake. But locals say these efforts prioritise visitors over indigenous communities whose livelihoods depend on the lake.

“The big businesses are not ours,” says a local boat operator. “We build boats ourselves, take loans, and earn only during the season.”

Some residents also report losing access to land and resources because private aquaculture or tourism ventures lease parts of the reservoir.

For communities already displaced once, these developments revive a familiar fear: marginalisation in the name of development.

Environmental pressures are also compounding these challenges. Invasive species such as Mikania micrantha (locally referred to as ‘Pichash’) due to erratic rainfall and changing water levels have disrupted fish breeding cycles and degraded ecosystems around the lake.

Despite supporting thousands of livelihoods, Dumboor Lake still lacks a comprehensive management plan.

“We depend on the lake, but no one manages it properly,” says a cooperative member. “How long can this continue?”

A New GEF-Backed Project Enters the Picture

Amid these overlapping pressures, a new biodiversity initiative supported by the Global Environment Facility (GEF) is drawing cautious attention.

The project – Conservation of Biodiversity, its Sustainable Use, and Fair and Equitable Sharing of Benefits in India (CONSERVE) – was approved at the 6th Global Biodiversity Framework Fund Council meeting, held under the framework of the Eighth GEF Assembly.

Backed by USD 13.8 million and implemented by the United Nations Development Programme and the World Bank, the project aims to strengthen community-led conservation while ensuring fair sharing of benefits.

At its core is a shift toward recognising Indigenous communities as key custodians of ecosystems – a long-standing demand in regions like Dumboor.

However, details of how the project will work on the ground and what it will specifically deliver for Dumboor’s fishers are not yet clear.

This uncertainty shapes local reactions: hopeful, but cautious.

Potential – and Unanswered – Questions

The initiative is expected to involve at least 25,000 people across project areas in governance and decision-making, including women.

For communities in Dumboor, this could mean,

• recognition of traditional knowledge
• participation in resource management
• access to financial support and new livelihood models
• improved ecosystem sustainability.

It also reflects the GEF’s growing emphasis on blended finance approaches – combining public and multilateral funds with other sources – to support environmental outcomes alongside community development.

Some, however, say the project needs greater transparency.

“How will local women be integrated into this project? What will be the means and level of women’s access to finance and opportunities to play a leadership role? These are some of the questions,” says a member of the CBD Woman’s Caucus who participated in the GEF global council.

According to the GEF, several gender-specific targets are included in the project design, ensuring that women will make up 50% of the estimated 25,000 beneficiaries and at least 40% of the beneficiaries of an Access and Benefit-Sharing financial mechanism that will be implemented as part of the project.

For residents, the real test lies in implementation.

“Most of this money might just go into big pockets and not to the locals,” says Tiprasa. “A lot of projects are launched in the region, but few bring actual benefit.”

He adds that many interventions fail because they do not account for local realities.

“The projects do not always consider the local challenges, so not all solutions help improve their conditions.”

Despite scepticism, some residents see promise in the project’s stated focus on community participation.

“We have always lived with this lake,” says Santo Reang, a local resident. “But no one asked us how to manage it.”

“This time, if they involve us properly, things can change,” adds Niranjan Debbarma, a fisher cooperative member. “We understand this lake better than anyone.”

The GEF noted that the GBFF recently developed one of the most stringent and progressive guidelines to ensure that Tribal Peoples and local communities are in the driver’s seat when designing and implementing every project and will act as bona fide partners in identifying priorities and implementing the project.

A Fragile Turning Point

For decades, Dumboor’s indigenous communities have adjusted to realities imposed from the outside – shifting from land to water and from stable agriculture to precarious fishing.

Now, with a new GEF-backed project on the horizon, change is possible – one that could finally recognise both the lake’s ecological importance and the people who depend on it.

But in Dumboor, hope is never uncomplicated.

For those who have lost land once before, the question is not just whether change will come but whether it will finally include them.
