In this study, the key conclusions of the IPCC special report on climate change and land (SRCCL) on land-climate interactions, food system and food security, land degradation and desertification, and sustainable land management were summed up. And the most controversial scientific issues in the report, such as greenhouse gas emissions from the food system, bio-energy and the estimate of carbon dioxide emissions and removals for the land sector were analyzed. Some scientific issues, such as the estimation of greenhouse gas emissions in the overall life cycle of food system, and the retrieval of greenhouse gas emissions based on remote sensing and ground-based measurement of atmospheric concentration and other data, need to be further studied in China. In the meanwhile, China should continue to implement sustainable land management, and improve corresponding technical measures and capacity-building.

Key words: Climate change, Desertification, Land degradation, Food security, Sustainable land management
