Mangrove ecosystems occupy a critical intersection of ecological security and human welfare, serving as frontline buffers against climate-induced coastal hazards while sustaining millions of resource-dependent communities across tropical coastlines.
Mangrove root systems dissipate wave energy, attenuate storm surges, and stabilise shorelines against erosion — functions that became starkly evident during the 2004 Indian Ocean tsunami, where mangrove-dense coasts recorded lower casualties. This protective capacity reduces disaster-response expenditure and infrastructure damage, making mangrove conservation a cost-effective climate adaptation strategy.
Mangroves sequester carbon at rates significantly higher than terrestrial forests, storing it in both biomass and waterlogged sediments — collectively termed 'blue carbon.' Degradation of these ecosystems releases stored carbon rapidly, making their conservation directly relevant to national climate commitments under India's Nationally Determined Contributions.
Mangroves sustain artisanal fisheries by providing nursery habitats for commercially important fish and crustacean species. Communities in deltaic regions — particularly in Sundarbans and along India's western coast — depend on mangrove-linked resources for food security, honey collection, and non-timber forest products, embedding ecological health within social resilience.
India's Integrated Coastal Zone Management framework and the Mangrove Initiative for Shoreline Habitats and Tangible Incomes (MISHTI) scheme reflect recognition that mangrove protection requires simultaneous attention to ecological integrity and community rights. Effective implementation demands convergence across forest, fisheries, and disaster management departments.
Mangrove conservation is neither purely ecological nor purely developmental — it is a governance challenge requiring integrated land-use policy, community co-management, and sustained financing to translate ecological resilience into durable human security along vulnerable coastlines.
