Water shortages are expected to increase significantly in the coming decades due to disappearing glaciers and decreased water supplies. This will likely lead to conflicts between countries over limited water resources, as seen historically in the Middle East and North Africa. Access to water and sea routes have also motivated wars in the past, such as the War of the Pacific where Chile gained territory and resources from Bolivia and Peru. As water is essential for life, disputes over this critical resource will continue to impact global stability and security.
