N'Djamena

N’Djamena sits at the confluence of the Chari and Logone rivers, a location that makes flooding a defining urban risk. Rapid growth, clogged drains and limited storm-water capacity have amplified exposure, while low-lying expansion increases the number of neighbourhoods dependent on functioning drainage and emergency pumping.

Recent flood-resilience work has shifted from reactive measures toward systematic maintenance and preparedness. Under the PILIER project, hundreds of kilometres of drainage have been cleared and repaired, pumping capacity strengthened and municipal teams trained. This infrastructure is important beyond disaster response: reliable drainage protects roads, markets, housing and public services during the rainy season. N’Djamena’s urban future therefore depends on integrating flood management into routine city operations while guiding new growth away from the most vulnerable land.
