Transboundary aquifers are underground water sources that cross international borders, making them a shared natural resource between two or more countries. These aquifers play a crucial role in providing water for drinking, agriculture, and industry in these regions. However, the management and sustainable use of transboundary aquifers can be challenging due to the potential for conflicts over access, control, and allocation of water resources. Research in this area focuses on understanding the hydrogeological characteristics of these aquifers, monitoring water quality and quantity, developing cooperative management strategies, and resolving disputes between countries to ensure sustainable and equitable use of transboundary aquifers.
