China’s South-North Water Transfer Project – the world’s largest engineering project – will eventually pump 45 billion cubic metres of water each year from the Yangtze to the Yellow River to feed the cities and coal fields of northern and western China, which are running out of water. The amount of water diverted every year will be equivalent to a second Yellow River.
The project, now estimated to cost 500 billion yuan (US$80 billion), remains a government priority, despite controversy over its expense, impacts on agriculture and mass relocations of communities.
