Summary for policymakers (SPM) for the IPCC special report on climate change and land (SRCCL) was approved on August 7, 2019. The report involved an assessment of different options for land-based climate change response and gained some new insights. These include quantitative assessment of the benefits of 40 comprehensive land-based measures for climate change mitigation and adaptation, combating desertification and land degradation, enhancing food security, conserving biodiversity and water resources, and sustainable development, linking addressing desertification, land degradation, and food security with climate change adaptation and mitigation measures, as well as assessment of risks, limitation, barriers and safeguard policies for implementing different measures. There are still some shortcomings in the classification of measures, the subject of climate change adaptation, the risk and policy analysis. These conclusions of this report will have important implications for China’s establishment of land-based responses to climate change, and the promotion of combating climate change and combating desertification and land degradation, protecting the ecological environment and enhancing food security, and formulating relevant policies.

Key words: Climate change, Land degradation, Desertification, Food security, Mitigation, Adaptation, Biodiversity, Sustainable development
