Flood Risk Analysis : A Panacea for Flood Risk Reduction in Lapai Lga, Niger State
The 2012 flood is one of the most devastating flood events in Nigeria in the last few decades. Flood incidence has become an annual event in many parts of the state destroying buildings, farmland, lives, and other valuable properties. The increasing spate of flood incidence in Nigeria and particularly in Niger state has become a major concern for government at all levels in the state. Therefore, this study is an attempt to develop flood risk model for flood prediction and flood preparedness in Lapai LGA of Niger State Nigeria. Six flood risk factors (Slope, Land use, elevation, drainage density, proximity to water body and soil) were identified from extant literature review and were adopted to develop flood risk model for the study area. Remote sensing data and GIS data for the flood risk factors were gathered from secondary sources. Quantitative data relating to effect of flood risk factors was also collated from stakeholder in communities with previous experience of flood in the LGA. The data collected were subjected to remote sensing and spatial analysis within ArcGIS 10.5 environment using the Arctoolbox extension. Descriptive analytical tool (percentage and median) was used to describe the area coverage of flood risk region in the area. The Multi-Criteria Decision Analysis (MCDA) was also used to determine the criterion weight of the flood risk factors. The study revealed that proximity (35%), elevation (25%), and slope (16%) accounted for 78% of the flood risk factors in Lapai LGA. The further study established that moderate flood risk areas in Lapai accounted for 24.4% of the total land area, 22.5% for high risk areas, and very high-risk areas accounted for 17.7%. The study concludes that although flood vulnerable areas are located in the northern and eastern region of Lapai LGA, it is the home to most rural communities in the LGA. The study recommends that conscious attempt must be made to discourage the development of flood risk areas to reduce flood disaster. The government must also develop strategies for proper resettlement of the inhabitant of the flood risk areas with alternative livelihood opportunities in the resettlement areas to ensure sustainability of the resettlement program
