Chinese soil experts warn of massive threat to food security http://apocadocs.com/s.pl?1281093881
If China's current rate of soil loss continues, a layer the size of Puerto Rico will be washed away in the next 50 years -- resulting in a 40 per cent decrease in food production, according to a study led by the country's Ministry of Water Resources, and science and engineering academies.... Scientists found that the total area of soil erosion has reached 1.61 million square kilometres nearly 17 per cent of total land cover. According to the study, many parts of the black soil in northeastern China -- the country's breadbasket -- have disappeared already, a trend that, if it continues, could put at risk food security for one million people.... "The most serious soil erosion exists in the slope land, especially in farmland," Lu Zongfan, a researcher at China's Institute of Soil and Water Conservation and consultant for the expedition, told SciDev.Net.
