Source(s):  World Bank, the (WB)

To support Mozambique in addressing these challenges and build climate resilience, the World Bank, jointly with the German Development Cooperation through KfW, have financed one of the first nature-based urban flood management projects in the coastal city of Beira.

This study also estimated the costs and benefits of vegetation of land and a combined measure which includes the construction of retention ponds, drainage channels, rehabilitation of existing drainage channels, outlets and flap gates, green revetment, dyke with green revetment, constructions of protection of bridge abutment and a certain area allocated for the protection and re-growing of mangroves, in Quelimane city.
