Context

A $200M World Bank IDA credit (approved October 2022) plus $60M Dutch/Spanish co-financing funds flood protection, resettlement and a planned ecological park for Dar es Salaam's Msimbazi basin, following $100M in damage from 2018 flooding.

Results

The project targets flood protection for 300,000+ residents and $30M already disbursed for resettling about 3,500 households; the nature-based elements (urban park, mangrove protection, reforestation) remain at planning/design stage, with grey infrastructure more concretely scheduled.

Implementation

Conditions for success
