Cities are not tapping into China’s massive South-North water diversion. Researchers raised concerns about the safety of Ethiopia’s Grand Renaissance Dam, groundwater levels dropped in India’s Andhra Pradesh state, and protests continued against a copper mine in Peru. A solar-powered desalination plant won USAID’s Desal Prize, and new regulations are expected to propel investment in ballast water treatment technology.

The second line of China’s massive South-North water diversion began operating in December 2014, bringing water from the Yangtze River Basin north to Beijing. Fewer than half of the cities along the route, however, have actually tapped into the new water supply due to high costs, experts say. The Wall Street Journal

Ongoing community protests against the $1.4 billion Tia Maria copper mine project in southern Peru pressured the government to say it may ask the company behind the project to modify its environmental impact study. The protests have centered around land and water pollution concerns in agricultural areas. Reuters
