Suitability Analysis for Resettlement Potential Sites of Flood Vulnerable Community in Kigali city, Rwanda

Increasing urbanization in Kigali is hampered by inadequate urban planning, posing significant problems such as increased vulnerability to natural disasters and population displacement. Floods are among the recurrent events in different districts of Kigali damaging standing crops and hindering human livelihoods. Addressing these challenges requires implementing research-based strategies and integrating policies for effective mitigation. This study aims to analyze potentially suitable sites for resettling flood-vulnerable communities in the Nyarugenge district, which is among the highly vulnerable areas of Kigali city. The integration of an Analytical Hierarchical Process (AHP)-based Geographic Information System (GIS) and multicriteria decision analysis has been used to analyze different indicators of flood risk and resettlement suitability, such as elevation, slope, rainfall, land use land cover (LULC), soil texture, proximity to rivers, proximity to roads, population density, proximity to education facilities and proximity to the health center to obtain a suitability map. The result of the study showed that over 50
