A Community-Led Mangrove Restoration Model for Climate Resilience, Livelihood Security, and Biodiversity Conservation in the Indian Sundarbans

Abstract

Mangrove ecosystems represent one of the most valuable natural assets on Earth, providing indispensable ecological, economic, and social benefits to millions of people living in coastal regions. Besides supporting rich biodiversity, mangroves function as natural barriers against cyclones, tidal surges, coastal erosion, and saltwater intrusion while serving as some of the world's most efficient carbon sinks. Despite these significant ecosystem services, mangrove forests are experiencing rapid degradation due to climate change, unsustainable land-use practices, industrial expansion, and increasing anthropogenic pressure. The Indian Sundarbans, forming part of the world's largest contiguous mangrove forest, have become particularly vulnerable to these interconnected environmental and socio-economic challenges. Recurrent cyclones, rising sea levels, increasing salinity, riverbank erosion, and declining agricultural productivity have significantly weakened the resilience of local communities, forcing many households into poverty, seasonal migration, and livelihood insecurity.

This paper presents The Community Forest, an innovative, community-driven mangrove restoration model implemented in the Indian Sundarbans of West Bengal. Unlike conventional afforestation programmes that primarily focus on ecological outcomes, this initiative integrates ecosystem restoration with livelihood generation, community empowerment, climate adaptation, and long-term environmental stewardship. The model positions local communities not merely as beneficiaries but as active planners, producers, and custodians of ecological restoration. Women, marginal farmers, unemployed youth, and landless labourers participate in every stage of the restoration cycle, including propagule collection, nursery development, plantation, maintenance, monitoring, and ecosystem protection.

The initiative adopts a decentralized production framework that combines indigenous ecological knowledge with scientific guidance to maximize plantation success and ensure long-term sustainability. By assigning economic value to every mangrove sapling through sponsorship, adoption, and future carbon financing mechanisms, the project creates continuous livelihood opportunities while simultaneously restoring degraded coastal ecosystems. This integrated approach demonstrates that environmental conservation and rural economic development can reinforce one another rather than compete for limited resources.

The paper outlines the conceptual framework, implementation methodology, phased action plan, and climate-finance potential of the initiative. It further discusses how community participation strengthens ecological resilience, promotes social inclusion, enhances adaptive capacity, and contributes to multiple Sustainable Development Goals (SDGs), including No Poverty (SDG 1), Gender Equality (SDG 5), Decent Work and Economic Growth (SDG 8), Climate Action (SDG 13), Life Below Water (SDG 14), Life on Land (SDG 15), and Partnerships for the Goals (SDG 17). As climate risks intensify across vulnerable coastal landscapes worldwide, The Community Forest offers a scalable, replicable, and economically sustainable nature-based solution capable of generating measurable environmental, social, and climate benefits.
