Mangrove restoration is increasingly being linked to global carbon markets, creating new sources of climate finance while raising questions about who actually benefits. On Pakistan’s Indus delta coast, a 350,000-hectare mangrove project illustrates this tension. By absorbing and storing carbon dioxide, restored forests can generate mangrove carbon credits that are sold to companies seeking to offset emissions. Yet these forests already provide substantial value to nearby communities through storm protection, fishing, firewood, honey and other resources.
The growth of mangrove carbon credits highlights a fundamental difference between market value and local value. Carbon stored in forests can be measured, certified and traded internationally, while benefits such as food, coastal protection, cultural traditions and access to natural resources are much harder to price. As climate finance expands, there is concern that funding will continue flowing toward benefits that are easiest to measure and sell rather than those most important to local communities.
This issue is particularly important as governments seek to increase adaptation finance for communities facing stronger storms, rising seas and other climate impacts. Mangrove restoration can strengthen coastal resilience while creating employment, training and conservation opportunities. However, carbon projects can also involve networks of brokers, verifiers, certifiers and other intermediaries that receive portions of the revenue before money reaches local residents.
Evidence suggests benefit sharing remains inconsistent. A Carbon Market Watch review of 47 carbon-credit project documents found only 15 mentioning benefit sharing, while just four provided evidence that benefits had actually been shared with local or Indigenous communities.
Financial payments are only part of the issue. Restoration can impose trade-offs on people who depend on mangroves. Protecting forests for carbon storage might restrict fishing or wood collection, while planting particular species to meet biodiversity or carbon objectives may reduce access to resources traditionally used by residents. Restoration designed around standardized measurements can also produce ecosystems that differ considerably from the diverse forests communities previously relied upon.
Local knowledge could help address these challenges. Communities living around forests such as the Sundarbans have developed practices governing how mangrove resources are used and protected over generations. Incorporating this knowledge into restoration could improve decisions about where and what to plant while encouraging long-term stewardship after project funding ends.
The experience of Malaysia’s Matang mangroves also demonstrates how definitions of successful forest management change over time. The same forest has been valued for charcoal, timber, biodiversity and, increasingly, carbon. Biodiversity credits could add another commercial value in the future.
Ultimately, the debate surrounding mangrove carbon credits is not simply about how much money communities receive. It is also about who decides what successful restoration looks like. A project can restore a forest and generate valuable carbon credits while still leaving local residents with fewer resources or less access.
Effective mangrove restoration therefore requires communities to participate directly in defining success, managing trade-offs and sharing benefits. Carbon can be measured precisely, but the social costs of producing those credits are much harder to quantify. As climate and adaptation finance grows, ensuring that communities help set the terms could determine whether mangrove restoration delivers both environmental and social benefits.
