Residents worry about Majimbini River flooding

As the rainy season approaches, people in M'tsapéré, part of the Mamoudzou commune, are increasingly concerned about flooding from the Majimbini River. The local government organized a "resilience village" on National Resilience Day to raise awareness about natural risks and showcase prevention tools.

River appears calm but poses hidden risks

In the Mrowahandra neighborhood, the Majimbini River was at its lowest level on Tuesday, with only a faint stream visible between rocks, plants, and waste. Small puddles, where guppies live, were scattered around, stained by soap and laundry detergent used by women and children. Despite the quiet scene, residents are aware of the river’s potential to rise quickly and cause flooding.

Past tragedies highlight dangers

Historical incidents show the river’s risks: a 19-year-old drowned in Passamaïnty in 2015, and another young boy was found dead in the Kwalé River in 2026 after being swept away by heavy rains. His body was discovered on Kwalé Légion Street by the gendarmerie. These events have left lasting concerns among locals.

Residents call for better infrastructure

Local residents, like 17-year-old Saendati, point out the lack of safety barriers on the bridge, which has led to drownings. Many residents cannot swim, and the bridge is seen as a danger zone. Toioumidine Daroussi, a 25-year-old entrepreneur, recalls a person being swept away while crossing the bridge and calls for infrastructure changes like tunnels and waste filters to reduce flood risks.

Waste in the river worsens flooding

Residents also highlight the impact of waste disposal in the river, which raises water levels and blocks the flow. Obstructions like sheet metal are visible in the mud, increasing the risk of flooding. This waste not only harms the environment but also makes the river more dangerous during heavy rains.

City launches awareness and prevention efforts

To address these issues, the City of Mamoudzou, with partners, set up a "resilience village" to educate residents and showcase prevention tools. These include the City's Community Safety Plan, the Majimbini Flood Prevention Action Program, and the Risk Prevention Plan, alongside support from the French Red Cross for disaster preparedness.

Authorities stress protection and awareness

Anli Bounou, director of urban planning, warned that water can rise suddenly after rain on the hills. He emphasized the need to avoid deforestation and protect the riverbed from erosion. The CADEMA is working to shield the riverbed and reduce risks.

Prevention involves many actors and behaviors

Authorities use WhatsApp groups, mosques, and neighborhood associations to inform residents about risks. DEALM agents noted that construction in high-risk areas is banned, and responsibility for damages depends on factors like residence location and disaster circumstances. Nearly 90% of Mahoran territory is exposed to natural hazards, with over 40% facing major risks. Efforts to change behaviors, especially reducing waste in natural areas, are crucial to lowering flood risks.
