Monsoons drive seasonal variations. Yet climate change threatens to disrupt the regular, alternating periods of rain and arid dryness. The dry season may become more arid, driving water demand, while the rainy season may condense higher precipitation levels into shorter periods, increasing the possibility of heavy flooding while decreasing the ability to capture and store water. Increased rainfall and flood conditions facilitate the spread of disease in areas where the population lacks access to clean water and sanitation. Thus, managing water scarcity is a critical challenge for many Asian nations with similar climates.
