2/3 of irrigated agriculture depends on mountain waters.
Mountain water sources, including glaciers and snowmelt , are critical for global food security as they supply freshwater for irrigation to over 40% of the world's agricultural land, impacting billions of people downstream. However, climate variations threatens this supply through rapid glacier melt , which can lead to initial flooding followed by long-term water shortages, reduced crop yields, and increased food insecurity, especially for mountain communities. How mountains contribute to food security " Water towers of the world ": Mountains store large amounts of water in glaciers and snowpack, slowly releasing it as a reliable source during warmer seasons and dry periods. Irrigation : This stored water feeds major river systems, providing irrigation for agriculture in both mountain valleys and downstream lowlands, supporting 40% of global irrigation. Supports agriculture: Reliable water access is crucial for crop production and livestock, with 70% of freshwater usa...
