Communities’ Perceptions and Coping Strategies to Flood Hazard in a Peri-Urban Catchment: The Case Study of the Zio River Basin, Togo, West Africa

Climate and land use changes have exacerbated the frequency and intensity of floods in West Africa. In Togo, the communities of the Zio river sub-basin are regularly affected by flood hazard with severe socio-economic consequences. The main objective of this article is to contribute to the improvement of the resilience of these populations through a better understanding of their perceptions and coping strategies to flood hazards. To achieve this goal, a mixed method consisting of household surveys, focus groups and direct observation is used. In addition, the data collected at the household level focused on the perceptions of the flood (origin and cause), the socio-economic impacts as well as the coping strategies. The results indicate that more than 80% of the households are affected by floods and the main negative consequences are the destruction of houses (40.8%), and interruption of socio-economic activities (58.4%). In addition, the efforts to cope with the severe impacts of floods include embankment (71.6%), storage on occasional shelves (52.3%), digging ditches (26.6% and the construction of cement houses with fairly raised foundations (13.1%). This study shows that is important to integrate indigenous knowledge and local population’s opinions in the flood risk management plans in order to increase their resilience.
