MARSEILLE, France (AlertNet) – Water must be used more efficiently and its waste reduced if the world is to meet rising food demand from a fast-expanding population amid the pressures of climate change, experts have said ahead of World Water Day.
Marked each year on March 22, the United Nations hopes the 2012 event will focus attention on water’s critical role in feeding the world.
The U.N. Food and Agriculture Organization (FAO) says the world will have to produce up to 70 percent more food to feed a global population expected to reach 9 billion people by 2050, from the current 7 billion. That will require better management of water, boosting farmers’ resilience to climate shifts, and cutting food and water waste.
Water consumption by agriculture is estimated to rise 19 percent by 2050, but the figure could be much higher if crop yields and production efficiency don’t improve dramatically, warns the latest U.N. World Water Development Report.
Water scarcity already affects more than 40 percent of people on the planet, and two-thirds could be living under water-stressed conditions by 2025, according to the FAO.
