This study aim at examines and map spatio-temporal impacts of climate change on food crops yield and its implication on population using Geographic Information System (GIS). Major regions where food crops were highly produced in Nigeria were selected and rainfall data for 30 years (1970 to 2000) were used for the Geospatial analysis. GIS Interpolation and other geospatial Analysis techniques were carried out to map the impacts of climate variability on food crop yield. The results of the analysis and the maps produced show that inter-annual climate variability brings about the differences in food crop availability consequently affect people in Nigeria.
