Environmental Impacts of Floods in Malanville

This study aims to determine the impact of the floods on the environment in the township of Malanville. The climatic data (precipitation from 1971 to 2018) of the Kandi station, map data and social-anthropological data were used. The sensitivity matrix made it possible to assess the level of vulnerability of the municipality to floods. Several factors responsible for the floods in the commune of Malanville were identified: the excess rainfall during the period of 1998- 2018, the strong irrigation of the municipality (the Sota and the Niger River), the low position of the municipality (slope <2) and human activities in swampy areas. All of its elements are aggravating factors and inevitably cause flooding with each rising water in the most vulnerable areas. The agricultural sector and ecosystems are the most exposed to floods with exposure indices of 73.3% and 86.67% respectively.
