Antananarivo faces pressing challenges related to urban floods and water pollution, which have wide-ranging impacts on its economy, and environmental conditions. The integrated master plan, with its focus on Nature Based Solutions (NbS) and disaster evacuation planning, aimed to enhance flood resilience and living conditions in, specifically, low-income neighborhoods. The project, the design and evaluation of NbS for disaster evacuation and flood risk reduction, will contribute to achieving the objective of improving urban living conditions and strengthening of flood resilience in Antananarivo's low-income communities situated along the Ikopa River floodplains.
