N’Djamena’s Resilience Against Floods: Lessons from the 2024 Disaster

In October 2024, N’Djamena faced significant flood challenges as the Chari River rose markedly. However, improvements in drainage systems and emergency measures through the PILIER project effectively reduced the impact of floods, safeguarding communities. The city’s proactive response differs significantly from past disasters, showcasing increased resilience and effective management of natural crises.

In October 2024, N’Djamena, Chad’s capital, faced significant rain and flooding due to the Chari River reaching 8.18 meters, marking an increase from the previous year. The recent climate crisis has led to devastating impacts across the region, with 576 fatalities and millions displaced since July 2024. These floods represent the worst natural disaster Chad has experienced in decades, reminiscent of historical events from the 1960s.

Unlike the catastrophic floods of 2022 that drove many to seek refuge, N’Djamena demonstrated improved resilience in 2024. The Chadian government implemented the Integrated Flood Control and Urban Resilience Project (PILIER), with support from the International Development Association. An emergency plan of $13 million was established to mitigate expected flooding, leading to significant infrastructure improvements.

Between April and September 2024, substantial efforts were made to restore N’Djamena’s 250 km drainage network, removing years of sludge and waste, thereby enhancing water flow. The project also supplied powerful motor pumps to aid in efficient water drainage, marking a significant improvement compared to previous years. Sarmadji Oumar, the city’s director of roads, praised these advancements, stating that they have significantly reduced the number of households affected by flooding this year.

The challenges posed by rising waters were closely monitored through coordinated efforts of road crews, who responded promptly at the first sign of flooding. Emergency dikes were raised, and vulnerable points along the Chari River were reinforced. This multi-faceted approach helped contain flooding effectively and safeguarded the city.

In summary, N’Djamena’s experience with flooding in 2024 showcased the city’s enhanced resilience due to preventive measures and infrastructural improvements. The PILIER project played a crucial role in organizing efforts to manage flood risks, ultimately saving lives and reducing the impact on communities compared to past disasters. The collaboration between government initiatives and international support has been instrumental in mitigating the consequences of climate change-induced flooding in the region.
