Land Use Change and Climate Change

Energy is a pivot, but we should not forget the other quarter source of the global carbon emission, the land use change. The process, scale, and pattern of global land use change are key to understand the driver of the regional impact of and response to global climate change. My research at Peking University College of Environmental Sciences then, and now the College of Urban and Environmental Sciences (Prof. CAI Yunlong, Prof. MENG Jijun, WAN Jun, PENG Jian, ZHU Xiaohua, Prof. LIU Hongyan) investigates the land use change in key western fragile ecosystem and around Beijing and their impact on rural poverty and urban sustainability. Scale effect is especially interesting to me as it reveals the different drivers and impacts at different scale level, it’s important to understand the scale effect and integrate theory and elements cross scales. Like price signal to the economic system, natural systems has a signal to govern the evolution of systems – complexity.
