Water policy trends threaten global food supply

If current water policies continue, farmers will not have enough water for irrigation to meet the world’s food needs by 2025, according to a new report by the International Food Policy Research Institute and the International Water Management Institute. The report presents computer-modeling projections of global supply and demand for food and water under three scenarios—business-as-usual, water crisis, and sustainable water use. Under business-as-usual, global annual losses in food production are predicted to reach 350 million metric tons by 2025 because of water scarcity. If current trends worsen and a water crisis ensues, food production is predicted to decline significantly, causing prices to skyrocket. On the other hand, if total global water consumption is reduced by 20% over business-as-usual levels and industrial demand for water decreases by 35%, food production is predicted to slightly increase and food prices to decline slowly by 2025.
