China Flattening Mountains to Create More Buildable Land
I’m thinking China might come to regret this craziness:
Scientists have criticised China’s bulldozing of hundreds of mountains to provide more building land for cities.
In a paper published in journal Nature this week, three Chinese academics say plan to remove over 700 mountains and shovel debris into valleys to create 250 sq km [96 sq mi] of flat land has not been sufficiently considered “environmentally, technically or economically.”
One of the largest projects began in April 2012 in Yan’an in the Shaanxi province, where the aim was to double the city’s area by creating an additional 78.5 sq km [30.3 sq mi] of land.
Soil erosion increases the sediment content of local water sources. In Shiyan, Hubein province, pounding hills into valleys caused landslides, flooding and altered water courses. This had serious implication for the city as it lies close to the headwaters of the South-North Water Transfer project, an endeavour to divert river waters along channels to Beijing.
In Langzhou, Gansu province, work was temporarily halted because of air pollution levels caused by dirt from the excavation. No one had thought to damp the soil to stop it flying in the wind.
