Malaria is a mosquito-borne infectious disease that affects humans posing as a severe public health problem in which Nigeria has the highest number of global cases. Geospatial technology has been widely used to study the risk and factors associated with malaria hazard. The present study is conducted in Ibadan, Oyo state, Nigeria. The objective of this study is to map out areas that are at high risk of the prevalence of malaria by considering a good number of factors as criteria that determine the spread of malaria within Ibadan using Open source and Landsat remote sensing data, and further analysis in GIS-based multi-criteria evaluation (MCE). This study considered factors like climatic, environmental, socio-economic, and proximity to health centers as criteria for mapping malaria risk. The MCE used a weighted overlay of the factors to produce an element at risk map, malaria hazard map, and vulnerability map. These maps were overlaid to produce the final malaria risk map which showed that 72% of Ibadan has a risk of malaria prevalence. Identification and delineation of risk areas in Ibadan would help policy makers and decision managers to mitigate the hazard and improve the health status of the state.
