Water stress refers to the condition where the demand for water exceeds the available supply, leading to competition for water resources among different users or sectors. This can result in water scarcity, reduced water quality, and negative impacts on ecosystems, agriculture, and human health. Research in the field of water stress focuses on understanding the causes and consequences of water scarcity, developing sustainable water management strategies, and finding ways to mitigate the effects of water stress on communities and the environment. This research area is crucial for addressing global water challenges and ensuring a secure and reliable water supply for future generations.
