AbstractSustainable use of groundwater is critical to China's present and future food security. Natural groundwater resources of Huang-Huai-Hai plains (HHH), the region hat produces 60-80% of China's wheat (Triticum aestivum) and 35-40% of its maize (Zea mays), are being jeopardized by excessive water withdrawal. While previous studies have assessed the groundwater depletion rate in parts of this region, there is a lack of data on the rate of groundwater depletion and the corresponding change process analysis at the entire scale in the HHH. In this article , we document that the groundwater is being depleted at a mean rate of 0.46 +/- 0.37m year(-1) for the shallow aquifer and 1.14 +/- 0.58m year(-1) for deep aquifer. Based on the general specific yield of aquifer in the HHH, the rate of loss of total groundwater in the entire region is 8.32-10.75 km(3) year(-1). The severity of groundwater depletion is attributed to the long-term intensive irrigation for increasing crop yields and total biomass production in the HHH. Increasing 1 million Mg of wheat production lower the deep groundwater by 1.8m(e.g., in Dezhou in the flood and coastal plains) and the shallow groundwater by 0.37 m (e.g., in Shijiazhuang in the piedmont plains). Thus, effective measures must be adopted to mitigate groundwater depletion for sustaining the present level of food production in the HHH.
