Interpreting the impacts and adaptations of food systems in the Sixth Assessment Report (AR6) of the Intergovernmental Panel on Climate Change (IPCC) Working Group II (WGII) is important for the scientific understanding of the frontiers of the international discipline of climate change impacts on agriculture.The newly released IPCC AR6,on the basis of further elaboration of food production capacity,planting layout,pest and disease impacts,further confirms the negative impacts of anthropogenic warming on food systems,discusses climate risks in food processing,transportation and consumption,extends the review of food impacts in complex ecosystems,and expands the analysis of climate change impacts on the entire chain of food production-processing-transportation-consumption.It extends the attribution of impacts and enriches the scientific understanding of agro-environmental impacts.As for the adaptation capacity of food systems,it emphasizes the development pathway of climate resilience based on the synergy of adaptation and mitigation,the adaptation assessment has gradually shifted from the theoretical aspects of adaptation capacity and adaptation methods to the assessment of adaptation implementation and effectiveness,and the regional specificity and effectiveness of adaptation actions are identified.This assessment emphasizes the detection and attribution of climate change impacts on crops,focuses on the impacts of climate and agro-environmental change,introduces ecosystem-based adaptation schemes and technologies,and assesses the feasibility and effectiveness of existing adaptation technologies.The contents of the report are important references for China to strengthen its capacity in agricultural impact assessment and to catch the international dynamics of the discipline.
