Assessment of Quality of Life Using Geographical Information System Approach for Poverty Alleviation Decision-Making
The effectiveness of the mapping and assessment of Quality of Life (QoL) in the identification of problemareas and in monitoring development policies makes it a suitable method in poverty studies. In an attemptto enhance QoL as a strategy for poverty alleviation decision-making, this research has adopted theanalytical tool of Geographical Information System (GIS). Twelve indicators were used to assess the QoLof Egor Local Government Area (LGA), Edo State, Nigeria. These indicators were grouped into threedifferent domains of life (social, economic and physical). Spatial autocorrelation check was performed onthe indicators to determine the spatial prediction method that was used to map each indicator. Of all theseindicators, only two were spatially auto-correlated. The two indicators were mapped using the InverseDistance Weighting (IDW). The other indicators were mapped using the voronoi polygons. The twelvemodels were used to model and assess QoL with the utilization of Multi-Criteria Decision Analysis. Theweights used for the combination of the various mapped indicators were given by the respondents. TheQoL model was cross-validated using leave-one-out (LOO) cross-validation method. The result showedthat the QoL of 61.53% of the geographic space of Egor LGA was below average, 17.94% was extremelypoor, and 14.55% was average, while the classes above average and excellent were not on the QoLmodel. In addition, the research identified priority development areas and concluded that the QoL of thepeople of Egor LGA was poor and required urgent conscious intervention by all development partnersincluding the government.
