The document summarizes a virtual roundtable on financing agricultural water held by the UN Food and Agriculture Organization. It notes that population growth and improved nutrition are increasing demand for agricultural water, while availability is decreasing due to factors like urbanization, climate change, and environmental stresses. Trillions of dollars in investment will be needed globally by 2050 to ensure sufficient water for agriculture. Adaptation is needed through technological innovations, policy reforms, and innovative financing mechanisms to modernize irrigation systems and make them more flexible and sustainable. Successful adaptation requires cross-sectoral cooperation across areas like finance, rural development, trade and the environment.
