BARCELONA - Using water more efficiently in everything from daily life to agriculture and industry would help reduce planet-warming emissions and curb climate change - a potential benefit that has yet to be widely recognised, the United Nations said on Sunday .

Using less energy cuts down further on the water needed to produce electricity, creating a virtuous circle, he said. Restoring and protecting wetlands, for example, is of"critical importance" because they store twice as much carbon as forests, while also preventing floods, purifying water and providing a habitat for animals and birds, the report said.

The best solution, the report said, is to invest in modern techniques that extract methane from organic matter in wastewater and use this biogas to generate the energy needed to treat the water - a method already used in some water-scarce countries like Jordan, Mexico, Peru and Thailand.
