This study was carried out to examine the Climate Change effect on groundwater resources in Benin City. The objectives were to acquire and analyze climate parameters, historical borehole data for detecting groundwater levels and represent the historical and future climate data on a map. The methodology involves data acquisition of sentinel 2 imageries for generating the land use land cover of the area, rainfall and temperature data (historical and future), soil data with the administrative location boundary map of the study area serving as an area of interest, together with the acquisition of borehole data (1990 and 2020). The result of the study was used to create a Groundwater table map of Benin City, by analyzing and interpolating some climate parameters such as rainfall and temperature, mapping the soil data of the study area which was also a key feature on how rainwater infiltrates the ground and recharge the aquifer, mapping the land use landcover of the study area which shows the urban sprawl and water demand in a specified area, and also the borehole data analysis from 1990 to 2020 which shows that Groundwater table has increased from 136.80m (deep) to 81.10m (high). The study described the effects of climate change on groundwater in Benin City and emphasized the urgency of adopting adaptive strategies to mitigate groundwater depletion. The exploration of sustainable practice and efficient water management provides valuable insights into addressing the challenges posed by climate-induced groundwater variations.
