How sustainable are current water sources—including alternatives such as desalination, wastewater reuse, and groundwater—for supporting irrigated agriculture in semi-arid and arid regions?
Over 80% of water use in semi-arid and arid regions is allocated to agricultural irrigation, making the sustainability of water sources in these areas a critical concern. The key trade-offs and long-term implications of relying on alternative waters sources are not fully understood.
