About the Cover

This study examines the perceived effects of flooding on lives and properties of the residents of Lokoja, Kogi State, Nigeria. The theory of resilience and concept of vulnerability provided the anchor while cross sectional survey research design was adopted for the study. Both primary and secondary data were sourced and multistage sampling technique was adopted where all the six communities (Adankolo, Felele, Ganaja, Lokongoma, and Sarkin Noma) affected were purposively surveyed. All the buildings that fell within 200 metres of the six floods affected communities were identified. The total numbers of buildings (2,018) were enumerated and 10% (202) of the sampled size were taken for the study. Issues that were considered included: Respondents socio-economic characteristics, respondents perceived number of flood occurrences in the study area, perceived impact of flooding on lives and infrastructure, level of household preparedness and diverse methods used in combating flood. Both quantitative (Logistic regression) and qualitative (FGD) techniques were used to analyze the data at p≥0.05 level of significance. The qualitative data collected were content analyzed. Flooding was discovered to cause damages to household properties (30.8%), household vehicles (3.5%), buildings collapse (0.5%), farmlands (7%) and death (0.4%).
