Feb. 14 (Bloomberg) -- Two-thirds of the world's population may be living in areas where there are water shortages by 2025, the United Nations' Food and Agriculture Organization said.
At present, 1.1 billion people don't have access to adequate clean water to meet basic daily needs, the FAO said today in an e-mailed statement. By 2025, 1.8 billion will be living in areas with ``absolute water scarcity,'' and two-thirds of the population may face ``water stress conditions,'' it said.
``Water has a major impact on the capacity of people everywhere to improve their lives,'' Pasquale Steduto, chief of FAO's Water, Development and Management Unit, said in the statement. ``In many regions, farmers trying to produce enough food and income face the added challenges of repeated droughts and competition for water.''
Sustainable and efficient use of water has become a key challenge; water use last century grew at more than twice the rate of the population, Steduto said. With about 70 percent of all fresh water drawn from lakes, waters and aquifers dedicated to agriculture, improving farming techniques is necessary to solve scarcity problems, he said.
Methods to be developed include trapping rainwater for use on farms, cutting down on leakage from irrigation systems, increasing productivity and changing crops, the FAO said.
The UN estimates the current population, of about 6.5 billion people, will increase to almost 8 billion by 2025. Two thirds of that would be about 5.3 billion people.
