Tanzania’s coastal areas – like those in many countries – face degraded natural ecosystems and coastal erosion. Coral and mangrove habitats are further endangered by the unsustainable use of natural resources. Incremental sea level rises further damages coasts and infrastructure. In the country’s largest city, Dar es Salaam, $5.3 billion in public and private assets are at risk from flooding. Coastal zone adaptation in this project includes the building and upgrading of sea walls, relocating aquifers and restoring mangrove forests to protect coastal communities from floods. A network of 87 local community groups was also established in the project areas to manage the mangrove sites. So far, 6 community rainwater harvesting devices have been built; at least 100 locals have been trained in coastal and climate vulnerability mapping; 1,000 hectares of mangrove habitat have been rehabilitated, while 10 boreholes and 15,000 litre of storage tanks have been installed to support water access.
