GEOSPATIAL ANALYSIS OF FLOOD VULNERABILITY IN JALINGO METROPOLIS, TARABA STATE, NIGERIA

This study analyzed spatial flood vulnerability in Jalingo Metropolis, Taraba State, Nigeria. The primary data were generated using a structured questionnaire. A multi-stage sampling procedure was used to administer questionnaire to three hundred and ninety-eight (398) respondents. The Flood Vulnerability Index [FVI] and Analysis of Variance [ANOVA] were used to analyze the data and presented using tables and maps. The result of the FVI computation with respect to the exposure factor showed that the Majidadi ward had the highest score of 0.665, making it the most exposed ward to flood. In terms of susceptibility, Majidadi Ward has the highest score of 0.624, making it the most susceptible to flood. The resilience factor computation revealed that the highest index score of 0.450 was recorded in the Barade ward. The resultant vulnerability map portrays that Majidadi has a very high level of vulnerability to floods, Sarkin Dawaki and Kona wards were found to be highly vulnerable to floods, Kachalla Sembe ward has a medium vulnerability to floods, while Barade ward showed a low level of flood vulnerability in the study area. The ANOVA results (F [4, 10] = 1.850, p > 0.05) showed that the flood vulnerability index factors in Jalingo metropolis did not statistically vary significantly. Based on these findings, the study recommends continuous flood inundation prediction, improved land-use planning and zoning, enhancing resilience while reducing the exposure and susceptibility levels of the metropolis based on the SDGs and SFDRR (2015), and continuous awareness campaigns on floods, climate change, and its attendant consequences
