项目简介

The impacts of climate change on farmland systems have become global and persistent. While farmland infrastructure can mitigate meteorological disasters and crop diversification can enhance soil carbon sequestration capacity, isolated case studies are insufficient to drive overall improvement in global resilience. Issues such as inadequate technological adaptability remain, making it difficult to address the holistic and cross-regional impacts of climate change. In recent years, China's high-standard farmland construction program has achieved remarkable results in enhancing farmland climate resilience. The ongoing Third National Soil Census will further clarify baseline cropland quality, laying a solid foundation for climate risk mitigation. Through the accumulation of technology and data, China has progressively developed an integrated technical framework for farmland climate resilience research, encompassing "status investigation, dynamic monitoring, and evaluation optimization."

This project leverages domestic strengths while focusing on shared global challenges. On one hand, it conducts in-depth analysis of the causal mechanisms through which farmland infrastructure and crop diversification contribute to yield stabilization and carbon sequestration. On the other hand, it addresses challenges in global application, including insufficient technological adaptability, imbalanced investment, and weak policy coordination. The project adopts "yield stability" as the core indicator of farmland climate resilience and "carbon sequestration" as the key regulatory indicator, using farmland infrastructure and crop diversification as respective entry points. At the landscape scale, it evaluates the supportive effects of plot layout, field roads, and other facilities on drought resistance, heat tolerance, and flood prevention. At the regional scale, it analyzes yield responses and changes in water use efficiency of diversified cropping patterns—including multi-cropping and rotation systems—under climate stress, as well as their regulatory mechanisms on soil carbon pools. Ultimately, the project seeks to elucidate integrated pathways for productivity enhancement and resilience regulation through the synergy of both approaches, build an integrated sky-air-ground agricultural early warning and allocation system, and conduct demonstration applications in typical regions worldwide.

Closely aligned with program guidelines, this project achieves innovation in both theoretical methodology and cooperation mechanisms. It not only advances the research perspective on agricultural impacts of climate change from the traditional focus on "high yield" to "yield stability," and modernizes monitoring and evaluation methodologies, but also breaks the conventional international cooperation model of "importing technology." Instead, collaboration follows the approach of "technology export—regional adaptation—effectiveness verification." The project is led by the Institute of Agricultural Resources and Regional Planning, Chinese Academy of Agricultural Sciences (CAAS), in collaboration with four leading domestic institutions: the Aerospace Information Research Institute (CAS), the Institute of Geographic Sciences and Natural Resources Research (CAS), China Agricultural University, and Central China Normal University, to innovate the theoretical and methodological framework. It also partners with eight internationally renowned institutions, including the Food and Agriculture Organization of the United Nations (FAO), the International Food Policy Research Institute (IFPRI), and the International Institute for Applied Systems Analysis (IIASA), which participate as external expert think tanks in case validation to enhance the global recognition of independently developed models and methods.

The project application has received the support of the Department of Farmland Construction Management under the Ministry of Agriculture and Rural Affairs, with comprehensive assurances in terms of policy, organizational, and resource support. Through comparative case studies spanning China, Europe, Africa, Central Asia, South Asia, and the Asia-Pacific region, the project is expected to yield globally applicable model methods, high-level academic publications, joint reports, and intelligent decision-support platforms. Throughout project implementation, regular communication with supervisory authorities is strictly maintained. With proper authorization, the project leverages authoritative international platforms such as FAO to disseminate the positive outcomes of China's soil census and high-standard farmland construction in enhancing farmland climate resilience. International seminars and technical training workshops will be organized to strengthen capacity building. Through South-South cooperation, technical assistance to food-insecure regions will be expanded. The project actively plans to establish an international scientific and technological collaboration network in the field of farmland climate resilience, providing robust support for serving national science and technology diplomacy strategies and enhancing China's voice in global agricultural climate governance.
