According to the Ministry of Constructionpreliminary statistics show that there are more than areas nationwide where groundwater has been over-exploited with an average annual groundwater depletion of more than 10 billion cubic meters. As a result, more than 60, square kilometers of ground surface have sunk with more than 50 cities suffering from serious land subsidence. In a Xinhua article fromChinese experts warned of future or current water shortages. Water resource usage was expected to peak in when the population peaks.

Comments Recently I traveled to Southeast Yunnan in China to see the spectacular Yuan Yang rice terraces, flooded and ready for spring planting. Yet China is facing a perilous water crisis. Severe droughts occurred inand Toby Simkin This winter, Beijing and the northern and eastern provinces had the worst drought in 60 years.

It has left 2. While torrential rainfall fell on the south this week, northern regions are still suffering from drought. Drought in southwest China. Bert van Dijk The water crisis is due to a number of interlinked factors.

Climate change is speeding up the melting of glaciers on the Tibetan Plateau, which is affecting the Yangtze, Mekong and Indus Rivers. Warming temperatures and changing precipitation patterns are causing droughts and increasing desertification.

According to World on the Edge by Lester Brown, over the last 50 years, 24, villages in north and west China were abandoned because of desertification, and the advancing Gobi Desert is now only miles from Beijing.

Water pollution has increased over the last three decades, penetrating coastal and inland water bodies, and both surface and groundwater.

Rivers and lakes polluted by industrial wastewater discharge, untreated sewage, and agricultural runoff force people to draw on groundwater, which results in falling water tables and the drying up of wells, wetlands, and lakes.

As groundwater is pumped faster than it can be recharged, wells must be dug deeper, raising the risks for saltwater intrusion and land subsidence. National water consumption will go from billion cubic meters trillion gallons to billion cubic meters by So not only must China deal with a drying climate and the water needs of a fast-growing urban populace, it must also satisfy the increased demands for energy—and energy production requires water.

Coal mine in Inner Mongolia. But between andInner Mongolia lost Today China can desalinatetons of water a day, but it aims to produce 2. However, desalination is expensive and requires energy, which, in turn, involves more water. When completed init will link the Yangtze, Yellow, Huaihe and Haihe rivers, and divert The eastern route, begun in Decemberwill transfer It is expected to be completed in The central route, begun in Decemberwill operate on gravity alone and divert 13 billion cubic meters of water each year from the Danjiangkou Reservoir on the Han River a Yangtze tributary to Beijing, Tianjin and other cities.

The ambitious and controversial western route will transfer water from three Yangtze tributaries across the Qinghai-Tibet Plateau through the Bayankala Mountains into northwest China. Designed to replenish the flows of the Yellow River for irrigation, it has not yet been given the official go-ahead.

Economists, environmentalists, academics and other critics have raised concerns about the SNWDP, fearing that water from the lower Yangtze for the eastern route will remain too polluted to use even after passing through numerous water treatment plants that are planned, and that further industrialization along the routes could pollute diverted water.

Because the south of China is also becoming drier, some worry that the southern provinces just do not have enough water to spare. And there are also concerns about the displacement of people, and the destruction of pasture and antiquities. It will not really resolve the whole problem…it cannot fill out even the current, existing gap, let alone that much bigger gap in the future, unless we do something very, very different in our water governance.

Plastic sheeting on fields. Renee Cho In a pilot program I saw in action throughout southwest China, farmers place plastic sheeting around crops, which collects rainwater that flows into the land and minimizes water loss.

Industry is conserving water through a progressive new system of water rights transfers in arid Inner Mongolia and Ningxia: The coal industry pays farmers for irrigation upgrades that save water which it can then use.Mar 29,  · But Beijing’s calculus is political: It is easier to increase the quantity of water resources, at whatever cost, rather than allocate a limited supply between competing interests.
