Coastal ecosystems generate diverse services, such as protection, production of food, climate regulation and recreation across the globe. These services are vital for extremely vulnerable coastal areas for enhancing present and future adaptation capacity under changing climate. Bangladesh has long coastline which provides opportunities to large population for multiple resource uses; and threats from extreme natural disasters. The CBACC-Coastal Afforestation is the priority initiative of Bangladesh NAPA that has come in actions under first LDCF adaptation project. The project has focused to reduce climatic vulnerability through enhancing resilience of coastal forests and adaptive capacity of communities. With a total of 6, 100 ha of new mangrove plantation and introducing 10 important mangrove species in existing monoculture areas, the project increased protective and carbon rich forest coverage, and also functional capacity of coastal vegetation to adapt to current and future climatic shocks. Concurrently, the project developed cobenefit regime for CbA through innovating integrated land uses for livelihoods of adjacent households. A new land use model (Forest, Fish and Fruit-Triple F) has been implemented to restore fallow coastal lands into community based livelihood adaptation practices. The Triple F practice has reduced inundation and salinity risks and freshwater scarcity in cultivation of agricultural crops and fish. The rational land uses improved household adaptation capacity of landless households through short-, mid- and long-term income generation. The project lesson has further focus to justify the land use innovation for harnessing potential opportunities of ecosystem-based adaptation in coastal Bangladesh.
