Abstract: Environmental suitability analysis of resettlement site is a complicated integration of various ecological and social factors that affect human livelihood. It is a crucial step for the achievement of the objectives of the resettlement programs as well as for guarantying the sustainability of the environment. Remote sensing and GIS technology offers a convenient and powerful platform to integrate spatially complex and different ecological factors for performing environmental suitability analysis. Hence, the main purpose of this study is the objective analysis and mapping of environmental suitability of Chewaka resettlement site in terms of the basic biophysical and socio-economic environmental factors and eventually identifying the suitable and unsuitable areas using Remote Sensing and GIS. The weighted overlay techniques are applied to arrive at the final environmental suitability mapping. The bio-physical and socio-economic factors used for evaluation of environmental suitability of the resettlement site are land use/land cover, climate, soil, topography, malaria prevalence, proximity, and infrastructural facility. The result showed that 34% of the area has highly suitable climate for human resettlement. However the majority of the area has a moderately suitable topography and soil, while only about 5% of the area has highly suitable infrastructural facility. Generally, the overall weighted suitability analysis of the area indicates that only 2% of the area has high suitability condition. The remaining 32% and 65% is moderately and marginally suitable for human resettlement.
