Abstract： China has made remarkable achievements in combating desertification over the past 70 years. At present, China has entered a new stage of combating desertification while facing many problems such as large desertification land base and high difficulty in combating desertification, and it is more important to meet the national strategic needs of ecological construction, rural revitalization, and the development and utilization of renewable energy in desert, Gobi, and wasteland areas. The strategic choice of combating desertification in China in the new era is overall improvement and key breakthroughs. The core of the strategy is whole-area governance, innovation-driven, and technology integration. The institutional arrangement of preferential policies is to fully implement the “one desert, four mechanisms” (cultivation, prevention, combating, and utilization), make every effort to win the “three iconic battles” of the “Three-North” battle, give priority to the implementation of key demonstration projects, and accelerate the update of policy. A new engine of science and technology will be built to improve the quality and efficiency for combating desertification, draw a bright vision of Chinese-style modernization featuring integration of production, life, and ecology and harmonization between human being and desert, and promote the “Chinese solution” of combating desertification to benefit the whole world.

Abstract： In 2015, the United Nations adopted the Transforming Our World: The 2030 Agenda for Sustainable Development, in which land degradation neutrality (LDN) is one of the important targets of the Sustainable Development Goal (SDG 15.3). However, due to varies indicative symptoms of land degradation in different climatic/geographical zones and land use types, the complexity of factors affecting land degradation or improvement, and the limits of spatial and temporal scope to define land degradation, for a long time, there was lack of common accepted methodology to identify land degradation, and short of key data set to establish reference baselines, and measure progress of SDG 15.3, which hinders the realization of SDG 15.3 by 2030. As a typical representative of a data-intensive scientific paradigm, Big Earth Data provides the possibility to solve this data gap. Focusing on two important aspects of SDG 15.3 reporting, namely baseline determination and progress monitoring, this article introduces the key challenges we faced, the potential of Big Earth Data and the practices we have taken. Finally, the prospects for harnessing Big Earth Data to facilitate SDG 15.3 in the future are outlined.

Abstract： Desertification, since initial recognition in 1927 and common definition in 1992, through its vicissitudes, is still one of the serious global environmental issues face the world and exists as the bottleneck of the development. Desertification threats the terrestrial ecological security and limits the sustainability of socio-economic development. In consideration of the impacts of desertification, an “Earth Cancer” and a persistent disease, the authors contribute four prescriptions of “good medicines” for the global initiatives to combat desertification, on the basic framework of Chinese strategies and experiences of “four horizontal beams and eight pillars”, in line with the 15.3 goal of Sustainable Development Goals (SDGs); namely, development of Protocol of United Nations Convention to Combat Desertification (UNCCD) and unification of Weights and Measures” (benchmarks and indicators) of the implementation and compliance of the UNCCD; setting up of global observation network to monitor the area change of dryland change; compilation of global natural desert (heritage) directory to leave behind landscape of aboriginal sand sea for future generations; initiation of “global governance action to combat desertification” to strive for achieving the target of Land Degradation Neutrality (LDN) at 2030.
