Protecting the sea is the only way to protect the people who depend on it
Off the coast of Sulawesi, the Bajau people of Torosiaje have long understood the sea not as a resource to be extracted but as a relationship to be maintained. As mangrove loss eroded the marine abundance their ancestors relied upon, this stilted village on the Molucca Sea chose restoration over retreat — replanting the root systems that shelter young fish and, in doing so, replanting the conditions for their own survival. Their effort asks a question the wider world is only beginning to take seriously: whether conservation and livelihood were ever truly separate things.
- Decades of coastal development and aquaculture expansion have stripped away the mangrove forests that once made these waters among the most productive in Southeast Asia.
- Bajau fishers watched their catches shrink year after year, forcing longer, costlier, and more dangerous journeys into open water just to sustain their families.
- Rather than abandon the sea, Torosiaje's community — working alongside conservation groups and local government — began the slow, muddy labor of replanting mangrove seedlings in degraded coastal zones.
- Young villagers who might have left for city jobs are instead staying, finding identity and purpose in restoration work that bridges traditional knowledge with a new kind of stewardship.
- Early signs show fish populations recovering in restored areas, and while historical abundance remains out of reach, the direction of change has quietly reversed from decline toward possibility.
The water taxi arrives at dusk, and Torosiaje emerges from the haze — a cluster of blue, yellow, and red houses perched on wooden stilts above the shallow Molucca Sea. Here, several hundred Bajau people, an Indigenous maritime community, have fished these waters for centuries, their lives shaped by tides and seasons. For generations, the arrangement was balanced: the sea gave fish, and the people took only what they needed. That balance has been breaking.
Mangrove forests are not decoration along this coastline — they are the engine of its marine life, their tangled roots serving as nurseries where juvenile fish grow before moving into open water. Over the past two decades, logging, aquaculture, and coastal development have gutted much of that coverage. The Bajau watched their catches fall, the abundance their grandparents knew becoming something they had to chase farther from shore, at greater cost and risk.
Torosiaje's answer was not to leave the sea but to restore what makes it work. Residents began replanting mangrove seedlings in degraded areas, tending them through the seasons alongside their fishing and boat maintenance — unglamorous work measured in mud and years. The decision came from within the village itself, from elders and fishing families who understood that their future was inseparable from the ecosystem beneath their stilts.
The restoration has drawn in younger generations who might otherwise have migrated to cities, giving them skills and a stake in the village's future. Results are still unfolding: fish populations in restored zones are showing early signs of recovery, though catches remain well below historical levels. The broader pressures on Southeast Asian fisheries are too large for any single village to overcome. But the trajectory has shifted — from certain decline toward uncertain but real possibility.
Coastal communities across Indonesia and beyond are watching Torosiaje closely, wondering whether the model can travel. The honest answer is that it requires patience, deep local knowledge, and sustained commitment — qualities the Bajau have in abundance but that are harder to transplant than seedlings. Still, what Torosiaje demonstrates is something quietly radical: that protecting the sea and sustaining the people who live from it may not be competing goals at all, but the same goal, approached from different directions.
The water taxi cuts through the darkening strait as the sun drops toward the horizon, and Torosiaje materializes from the gloom—a scatter of houses painted in blues and yellows and reds, each one balanced on wooden stilts driven into the shallow water of the Molucca Sea. This is home to several hundred Bajau people, an Indigenous maritime community whose ancestors have fished these waters for centuries, reading the tides and seasons the way others read maps. For generations, the relationship between the village and the sea has been reciprocal: the water provides fish, and the people take only what they need. But that equilibrium has begun to fracture.
The mangrove forests that ring the coast here are not merely scenery. They are nurseries—dense, tangled root systems where juvenile fish shelter and feed before venturing into open water. When mangroves disappear, the fish populations collapse. Over the past two decades, coastal development, aquaculture expansion, and logging have stripped away much of the mangrove coverage that once protected this region's marine productivity. The Bajau fishers of Torosiaje watched their catches decline year after year, the abundance their grandparents took for granted becoming something they had to chase farther from home, in deeper water, with greater risk and expense.
The village's response has been to reverse course—not by abandoning the sea, but by restoring the mangroves that make the sea productive. Working with conservation organizations and local government, residents have begun replanting mangrove seedlings in degraded areas, protecting young trees from damage, and monitoring their growth. The work is unglamorous: wading through mud, handling saplings, returning season after season to tend what you have planted. But the logic is clear. Mangroves take time to mature—sometimes a decade or more before they begin functioning as effective fish nurseries—but once established, they require no external inputs, no chemicals, no infrastructure. They simply work, the way they have always worked.
What makes Torosiaje's effort distinctive is that it is not imposed from outside. The village elders and fishing families made the decision themselves, recognizing that their survival depends on the health of the ecosystem they inhabit. They have integrated mangrove restoration into their seasonal rhythms, treating it as part of the annual cycle alongside fishing and boat maintenance. Young people who might otherwise have migrated to cities in search of work now find purpose in the restoration effort, learning skills their parents never needed and reconnecting with the marine environment in a different way.
The results are still emerging. Fish populations in areas where mangroves have been restored show signs of recovery, though it is early. Catches have not returned to historical levels, and they may never—the broader pressures on Southeast Asian fisheries are too great. But the trajectory has shifted. Where the trend was decline, there is now a possibility of stability. Where there was resignation, there is now work with a purpose.
Torosiaje's model is being watched across Indonesia and beyond. Coastal communities facing similar pressures—degraded mangroves, declining fish stocks, economic precarity—are asking whether the same approach might work in their waters. The answer is not simple. Mangrove restoration requires patience, sustained commitment, and the kind of local knowledge that only communities like the Bajau possess. But if it can be replicated, even partially, it offers a path forward that does not require choosing between conservation and livelihood. Instead, it suggests that the two might be inseparable—that protecting the sea is the only way to protect the people who depend on it.

La Conversación del Hearth Otra perspectiva de la historia
Why does mangrove restoration matter so much more than, say, just regulating fishing practices or limiting catches?
Because the fish have to exist before you can catch them. Without mangroves, there's nothing to regulate. The mangroves are the foundation—they're where the young fish grow big enough to survive in open water. You can have perfect fishing rules, but if the nurseries are gone, you're managing a collapse.
How long does it actually take for a replanted mangrove to become useful?
Years. Sometimes a decade before it's functioning as a real nursery. That's why this requires something most conservation efforts don't have—genuine commitment from the people who live there. You can't hire someone to plant trees and leave. The Bajau are doing this because they understand they're planting for their children's future, not next quarter's profit.
What happens if the mangroves come back but the fish still don't?
That's the real risk. Mangroves are necessary but not sufficient. Climate change, overfishing in adjacent waters, pollution—those all matter too. Torosiaje is doing what it can control. But they're also aware that restoration alone won't save them if everything else keeps degrading.
Is this economically viable, or is it survival desperation dressed up as conservation?
Both, honestly. The fishing economy was already broken. Catches were falling, boats were going out longer for less. So yes, this is partly desperation. But it's also the only economic strategy that doesn't require abandoning the place or accepting permanent decline. It's not profitable in the short term, but it's the only path to viability in the long term.
Why should someone outside Indonesia care about one fishing village?
Because if coastal communities can figure out how to restore their own ecosystems while maintaining their livelihoods, that's a model that could scale across the entire region. And because the alternative—watching these communities disappear, their knowledge disappear, their connection to the sea disappear—is a loss that affects everyone, not just the Bajau.
