Trowel Development Foundation is a community-based organization employing climate-adapted aquaculture technology to replant mangroves. Mangrove reforestation efforts have focused on planting native tree species in strategic areas, resulting in restored marine biodiversity, food security, and protection of coastal areas.
The initiative also works to increase local incomes and improve livelihoods through a value-chain system to market tie-crabs. The group has established five community-managed tie-crab farms that benefit 250 subsistence fishing households. This innovation has been implemented in idle fishponds, where mangrove-friendly and climate-adapted tie-crab fattening technology has been employed to double the income of fishing households.
