Floods have become common characteristics of climate change in recent years. In the Western part of Uganda, Kasese Municipality, at least five major flash flood disasters have been experienced since 2013 and have left a trail of devastation and human deaths in their wake. Because communities' survival is at stake, it's critical to understand how disaster vulnerability is built. Many vulnerability drivers, on the other hand, are frequently hidden and distant from the triggering events. With the projected increase in extreme flooding due to climate change, the research study focused on analysing the drivers of community vulnerability to flood hazards in Kasese municipality. To analyse the drivers of vulnerability, key informants and focus group discussion were used. The major drivers of vulnerability to flood hazards in Kasese Municipality were high levels of poverty, lack of adequate land for settlement and farming, lack of adequate information on disaster risk management, and lack of early warning system. However, none of these factors, by themselves, make the community vulnerable. Instead, they are mutually inclusive, with each supporting the other(s). The findings of the study can help the government and decision-makers strengthen policy actions by strengthening flood disaster risk reduction mitigation measures and guaranteeing optimal resource use to reduce future vulnerabilities and consequences.
