Potential impacts of cropland dynamics on farming developments in China by analyzing a fused crop production data

Based on the background of climate change and rapid population & land urbanization, we developed the theoretical hypothesis and questions. As we know, urban usually have good education, hospital and housing, so many rural people flow to urban and indirectly take away industry and property. So rural communities face many challenges, such as less people, land, industry and property at least. For climate change, challenges from flooding, drought, heat wave, lower temperature, and frost timing. And opportunities maybe from Increasing and northward accumulated annual temperature (AAT10), and lengthen the growing season. For urbanization, challenges from abandonment, and less cropping frequency. And opportunities maybe from well-facilitated farmland, land unified management, and intelligent agriculture. Rural revitalization and urban-rural integration are two good measures for rural development policy not only in China but in many global counties. Yet, how to catch the rural people and agro-workers' eye, and improve the food supply ability are important questions. We will show some recent study results about geo-spatial change of croplands and its impacts on farming developments in China over the past two decades in this congress.
