in the largest such project attempted on loess, a kind of wind blown silt. The project has destroyed farmlands while filling valleys with a kind of earth that may lack firmness and be vulnerable to disasters such as landslides, Li said.
Chinese scientists warn against Air Max 95 Lux plan to turn mountaintops into cities
In neighbouring Shaanxi province, Yan city aims to double its area by creating 79 square kilometres of flat ground in a project started in 2012 Air Max 95 25 Psi
Dozens of peaks up to 150 metres tall have been flattened to fill up valleys and create tens of square kilometres of land over the past decade. But there has been little assessment of the costs and environmental impact of these projects, researchers at Chang University said in a commentary published in the journal Nature.
BEIJING, China China campaign to shave off mountaintops and fill in valleys to make way for cities may come at too high a price in the pollution, erosion and flooding unleashed by the unprecedented redistribution of earth, Chinese researchers warned Thursday.
The first city to expand by bulldozing its mountaintops was Shiyan in central Hubei province in 2007. The transformation caused landslides and flooding, altered watercourses and increased the sediment content in local water sources, the commentary said.
In addition to causing air and water pollution, erosion, landslides and flooding, the projects have destroyed farmlands and habitat for wild animals and plants, the group said.
China government is in a multi year drive to move more rural residents to urban areas to develop into a more modern economy.
been done before in mining in the United States, it has never been carried out on the scale underway in China or used to construct urban areas, the researchers said. we believe the government should be cautious in promoting the projects before proper experiments have shown that they are technological, geological and environmentally feasible, he said.
I wonder as well if anyone done any analysis, not only on the water footprint but the energy footprint of actually constructing cities in this way, because cities need cement, they need steel. / content >
