One of the critical components in climate change mitigation lies in meeting the challenge of reducing global land carbon loss, as human demand increases. Yet, it is unclear which region and which form of commodity consumption were responsible for the greatest loss of land carbon. Here we assumed a uniform lifespan (20-year) for managed land and too...

In recent years, flows of many rivers and lakes have become reduced in arid and semi-arid regions around the world. The most typical examples of this phenomenon occur in Central Asia, and the reduction of the Aral Sea area is closely related to agricultural water use. However, due to a lack of continuous data in Central Asia spanning many years, “v...

The North China Plain (NCP) has suffered severe groundwater over-exploitation problems, and the large amount of irrigation water consumed by winter wheat is known as the major cause. The land fallow policy was adopted by the central government to encourage the abandonment of winter wheat, for the purpose of inducing protection and recovery of groundwater environment. However, the NCP is also the major winter wheat producing area of China, with a function of guaranteeing food security. The optimal allocation of winter wheat to the southern part of the NCP, where the water use of winter wheat mainly originates from natural precipitation and the pressure on the environment is much lower than that in the northern part, conforms to the ongoing trend of agricultural land use change, since evidences of winter wheat expansion were spotted in southern part of the NCP, and will be a reasonable choice to fulfill the win-win target between effective groundwater management and stable wheat supply. To what extent can winter wheat potentially expand in the NCP? How to optimally allocate winter wheat across the NCP? How will crop water footprint change after the spatially optimal allocation of winter wheat in the NCP? To answer the above questions, we will monitor the changes of agricultural cropping structure in the NCP using remote sensing technology, pinpoint the major alternative crops for winter wheat and the potential areas for winter wheat expansion, and select typical areas for the specification of driving factors and their mechanisms of households’ land use decisions. Then, we will construct a spatially explicit agricultural land use model, to optimally allocate winter wheat across the NCP under the constraints of land abandonment and food security and to calculate the compensation values for winter wheat expansion areas, and estimate crop water footprint and its spatial changes using China-AEZ model. We will also provide scientific suggestions for policies relevant to adjustment of agricultural cropping structure, guarantee of food security and protection of water resource in the NCP.
