Challenges and Innovative Development of Land Degradation Control Under Global Change

Human impacts on global climate, environment and life system have been increasing with an unprecedented intensity and speed equal or even over the natural change regime. In the multiple/rapid global changes it is indispensable to explore new theories and approaches in terms of land degradation control to establish healthy earth life supporting system for ensuring global sustainable development. This article presented an overall analysis of new challenges and new approaches of land degradation control under the global change, and shared China's experiences in land degradation control. It was highly recommended that land degradation control should be considered with a range of major global issues including climate change, biodiversity conservation, poverty alleviation in a broad context and the United Nations Millennium Development Goals, eventually with the aim at promoting green development and building a beautiful earth.
