Shanghai To Build Artificial Wetlands To Replace Destroyed Natural Ecosystems
Shanghai (AFP) Jul 18, 2007 The Chinese metropolis of Shanghai is to build its own artificial wetlands to replace natural ecosystems trampled by the city's unchecked development, state press reported Tuesday. The city will construct a wetland of 15 square kilometres (5.7 square miles) in its Qingpu district to act as a filter for water supplies threatened by pollution, the China Daily newspaper reported. The wetland will be built around Dianhan Lake, source of about 30 percent of the massive city's drinking water, it said, quoting local planning officials. Authorities came up with the plan amid rising concern over water supplies following a spate of pollution-linked algae blooms in major lakes in other parts of China that provide drinking water. Officials said Shanghai's water remains safe, though the paper said many visitors complain it tastes like bleach. "Shanghai's water source is being threatened, and we have to move quickly. It's crucial to protect the wetlands, which are an integral part of our water resources," said Cui Liping, vice director of the city's landscaping administration. Officials also will encourage farmers living around the lake to farm "properly" to protect the ecosystem. The rampant use of agricultural chemicals has tainted much of China's water supplies. State press have recently warned of a catastrophic recent decline in the nation's vital wetlands as development and industrialisation continue apace. Toxic algae blooms choked two of China's biggest freshwater lakes, Taihu and Chaohu, in late May and early June, forcing water supplies to millions of nearby residents to be temporarily cut. More than 70 percent of China's waterways and 90 percent of its underground water are contaminated by pollution, according to the State Environmental Protection Administration.

China Vital Wetlands Shrinking Due To Climate Change
Beijing (AFP) July 16, 2007Climate change is shrinking wetlands at the source of China's two greatest rivers and has already led to reduced water flows that could have an impact across Asia, state media reported Monday. The contraction of the wetlands, which serve a vital role regulating the flow of the Yangtze and Yellow rivers, comes as China is already struggling to meet the increased water needs of a fast-expanding economy. |
