The world is set to use far more treated wastewater to help irrigate crops and feed a rising population as fresh water supplies dry up, a team of U.N.-backed experts said on Thursday. A study led by Japan’s Tottori University and U.N. University’s Canadian-based Institute for Water, Environment and Health (UNU-INWEH) forecast “a rapid increase in the use of treated wastewater for farming and other purposes worldwide”.
