Water security refers to the availability, access, and quality of water for various purposes such as drinking, agriculture, industry, and ecosystem sustainability. It encompasses issues such as water scarcity, pollution, climate change impacts on water resources, and equitable water distribution. Research in water security focuses on understanding the challenges and developing strategies to ensure sustainable management and governance of water resources for current and future generations. This includes assessing and monitoring water availability, improving water infrastructure, promoting water conservation and efficiency, and addressing social and economic factors that influence water access and use.
