For instance, studies have shown that water resources quantity and quality will be seriously degraded by phenomenon. This paper examines effect of climate on future availability Gusau City, Zamfara State, Nigeria. The data obtained from three Regional Models (RCMs) ensembles gridded at 0.5o x spatial resolutions were used. analysis was carried out using ArcGIS (ArcMap, version 10.5) software comparison outcome made. findings show temperature increase as 1- 3oC 2040, 2070 2- 5oC 2100. Furthermore, rainfall under rcp 4.5 8.5 6.7% - 20%, 10% 20% 30% 2070v 2100 respectively. It further shows an +10% + 60% seasonal changes months April-May-June July-August-September These ultimately result surface run off aquifer recharge.
