面向可持续目标的传统农村家庭食物-能源-水耦合研究:框架构建

Food-energy-water nexus in traditional rural households to achieve sustainability goals:Framework construction

家庭食物-能源-水(FEW)3系统之间互相联系,对其中1种资源的管理政策调整会对另外2个系统产生不同程度的影响,需要深入理解其耦合关系。传统农村家庭屋顶和庭院的闲置率高,可利用潜力大,但城市家庭FEW的政策情景往往无法简单套用在农村家庭,尤其是仍保留传统村庄特点的农村家庭。通过深入梳理中国传统农村家庭FEW消费模式和国内外相关政策关联内容设计,全新构建了传统农村家庭FEW耦合研究框架。该框架由家庭FEW消费模块、屋顶/庭院利用模块和政策输入输出模块构成,能够清晰地展示政策实施中跨边界耦合影响发生的节点,提高对资源利用的理解和管理路径的识别。该框架可用于传统农村家庭FEW相关政策收集和制定、政策影响评估和政策优化,助力农村可持续发展和乡村振兴。

The interconnected systems of household food,energy,and water(FEW)are deeply intertwined.Adjusting management policies for one resource can significantly influence the other two,thus requiring a deeper understanding of their nexus relationships.In traditional rural household,the underutilization of roofs and courtyards presents a substantial opportunity for resource optimization.However,the FEW policy frameworks designed for urban households are not directly transferable to rural households,particularly those preserving traditional village characteristics.Through an analysis of consumption patterns in Chinese traditional rural households and a critical review of nexus policy designs both domestically and internationally,this study developed a novel FEW nexus policy analysis framework tailored for traditional rural households.This framework comprised a FEW household consumption module,a roof/courtyard utilization module,and a policy input and output module.It effectively highlighted the points of cross-boundary nexus effects during policy implementation,enhancing our comprehension of resource utilization and clarifying management trajectories.The framework serves as a tool to gather and shape policies pertinent to traditional rural households,evaluate policy impacts,refine policy approaches,and ultimately support sustainable rural development and revitalization efforts.
