Water is vital for life and development. However, water scarcity is a growing problem in Asia due to increasing populations and changing consumption patterns. Effective water diplomacy and cooperation between countries will be essential to ensure adequate access to water for all. The major rivers of South and East Asia, such as the Ganges, Brahmaputra, Indus and Yellow River, flow through multiple countries, so collaborative management and sharing of water resources will be needed to mitigate conflicts and allow sustainable development.
