Climate change influences water availability across various locations by altering the spatiotemporal patterns of precipitation and evaporation, hence affecting water supplies. Alterations in precipitation and evaporation characteristics resulting from climate change may cause variations in water availability, impacting both human populations and ecosystems. Research indicates that changes in the average and seasonal patterns of precipitation and evaporation can profoundly affect water supply systems, hydrology, agricultural productivity, and ecosystems. In this chapter, we discussed potential solutions to mitigate the consequences of climate change on water availability encompass: enhancing water storage and management, improving drought monitoring and early warning systems, adopting climate-smart agriculture and water reuse practices, safeguarding natural buffers, promoting rainwater harvesting, and increasing irrigation water productivity. Implementing these solutions necessitates a synthesis of technological advances, policy initiatives, and community-based strategies to improve water security and foster resilience against the consequences of climate change on water supply.
