Beijng is planning to build six lakes and two wetlands along the currently dry Yongding River (known as the Mother River of Beijing). Part of the river flows for 170 kilometres through several districts of Beijing.
The six lakes to be constructed are Mencheng Lake, Lianshi Lake, Xiaoyue Lake, Wanping Lake, Daning Lake, and Daotian Lake, and will 50 kilometers long and 270-hectare water area. Recently, the construction of Wanping Lake and Lianshi Lake started simultaneously at the lower reaches of the Yongding River. These lakes and wetlands are part of a bigger ecological corridor 170km long project which is budget to cost 17 billion yuan (2.5 billion USD).
The water required for the project is 130 million cubic meters is needed to recover Yongding River, and the water will mainly come from reclaimed water and rain. The Qinghe, Xiaohongmen, Lugou Bridge, Wulituo and Mencheng reclaimed water plants will help provide Yongding River with quality water resources that meet the three-star surface water standard. In addition, two million cubic meters of rain can be stored every year for use. A wetland will be built at the upper reaches of every lake in order to further purify the water and ensure that the water in the Yongding River can meet the three or even four-star standard of surface water.
The four lakes will be constructed and filled with water by the end of 2010. The bigger 170 kilometers long ecological corridor projects will be completed by 2014.
Eli Cohen recently gave a lecture as one of the Freshkills Park lecture series and the Freshkills Blog posted this on Wednesday
Eli Cohen gave a terrific talk Monday night on his work, as director of Ayala Water and Ecology, using plants to remove pollutants and contaminants from water, soil and air. We’re grateful to the huge crowd that poured into the Arsenal gallery for the event, to Laura Starr and Yamit Perez for putting us in touch with Eli and, of course, to Eli himself for sharing his work and his thoughts.
The Freshkills Park Blog post also includes the MP3 and PDF of the presentation for listening and viewing.

Annapolis intends to test a floating island in a local lagoon that, if successful, could help clean the water in the Chesapeake Bay, according to Mayor Ellen O. Moyer……
Floating islands are created from recycled plastics and planted with wetland plants that soak up nutrients from the water, said Steve Carr, the city’s environmental adviser. He said the project in Annapolis will act as a test to see whether the technology can be implemented in larger areas of the bay.

The latest edition of the Monthly Review (November 2009, Volume 61, Number 6) includes a paper from Jules Pretty is professor of environment and society at the University of Essex, UK. titled Can Ecological Agriculture Feed Nine Billion People?
Below is an extract from the paper
Something is wrong with our agricultural and food systems.Despite great progress in increasing productivity in the last century, hundreds of millions of people remain hungry and malnourished. Further hundreds of millions eat too much, or consume the wrong sorts of food, and it is making them ill. The health of the environment suffers too, as degradation of soil and water seems to accompany many of the agricultural systems we have developed in recent years. Can nothing be done, or is it time for the expansion of an agriculture founded more on ecological principles and in harmony with people, their societies, and cultures?

Turenscape (Beijing Turen Design Institute) has been awarded the Landscape Category award at the 2009 World Architecture Festival for a 22-hectare park in Tianjin, China – The Adaptation Palettes: Regenerative Landscape Design
Through Regenerative Design and by allotting landforms, the natural process of plant adaptation and community evolution is introduced to transform a former deserted shooting range used as a garbage dump, into a low maintenance urban park; providing diverse nature’s services for the city including containing and purifying storm water; improving the saline-alkali soil, providing opportunities for environmental education and creating a cherished aesthetic experience.
