water scarcity Tag

An international study published in the American Geophysical Union journal Earth's Future predicts that agricultural water scarcity is expected to increase in more than 80% of the world's croplands by 2050. Researchers developed a new index to measure and predict water scarcity in agriculture's two major sources: soil water that comes from rain, called green water, and irrigation from rivers, lakes and groundwater, called blue water. The researchers found that under climate change, global agricultural water scarcity will worsen in up to 84% of croplands, with a loss of water supplies driving scarcity in about 60% of those croplands.
