Introduction

 
FAQ
Does China still have land reserves for (rain-fed) cultivation?
Yes. According to the IIASA China AEZ model the country has - in addition to its current cropland area - some 30 million hectares of land with grain cultivation potential. Much of these reserves are in northern China, such as in Heilongjiang (see the in-depth analysis).
Some 15 million hectares of this reserve, however, would need irrigation to become productive. The development of additional water resources are therefore critical for China's food security.
There are also large grassland areas, which could be used more intensely for livestock production. However this would require significant changes in livestock production methods (stable production).
While China has significant land reserves, massive investments into the transportation infrastructure, water supply, and changes in production management would be necessary to utilize the resources.
