农食系统是保障国民营养和粮食安全的关键基础,是实现全面小康和国家安全的重点环节。当前,我国发展环境正发生深刻复杂的变化,农食系统必须向高效的、营养的、可持续的、有包容性和韧性的方向转型,以应对多重风险叠加的影响。农食系统转型目标与乡村振兴的总要求协调统一,应从发展多赢型或集成式技术创新、优化农业支持保护政策、建立跨部门协同工作机制、健全农村社会保障体系、改善农村发展条件等路径推动农食系统转型,助力乡村振兴。

Transformation of Agrifood Systems to Boost Rural Revitalization

Transformation of agrifood systems is the critical basis for guaranteeing national nutrition and food security and it is a key link for achieving a well off society and national security in all respects. China''s development environment is experiencing profound and complex changes. Agrifood systems must be transformed to be efficient, nutritious, sustainable, inclusive, and resilient to tackle the intertwining challenge of multiple risks. This paper argues that goals of agrifood systems transformation are in line with the general requirements of rural revitalization. To this end, this paper proposes ways to promote rural revitalization through agrifood systems transformation, including developing multiple-win technologies and support for bundling innovations, reshaping agricultural subsidies, setting rural social protection networks, establishing cross-departmental collaborative working mechanisms, and improving rural development conditions.
