跨境流域水−能源−粮食关联关系研究进展与展望

Progress and prospect of water-energy-food nexus in the transboundary river basins

跨境流域水−能源−粮食关联关系的协调,是保障跨境水安全与生态安全、维系流域国家地缘安全和可持续发展的核心议题。通过系统梳理跨境流域水−能源−粮食关联关系研究的发展历程和前沿进展,将研究层次划分为针对内部核心指标的关联关系研究、耦合外部关键指标的关联关系研究、未来不确定性引发的应对措施的关联关系研究以及考虑水利益共享的跨境合作研究。判识了当前定量评估方法的类型、特点和面临的挑战,从跨境流域现实需求的视角指出今后亟需重点关注的发展方向,即加强信息共享和数据挖掘、促进关联关系的耦合互馈机制研究、增强关联关系定量评估模型的开发和应用、深化关联关系未来不确定性的研究、推动多利益主体的互利互惠合作,以便更好地促进跨境流域水资源合理开发利用,实现更深层次的地缘合作。

In the context of transboundary river basins,the water-energy-food nexus is of great significance for water security and ecological security,as well as for maintaining the geopolitical security and sustainable development of transboundary countries.The present study systematically reviewed the frontier progress of the water-energy-food nexus research in the transboundary river basins.These studies can be grouped into four categories:research on the internal core nexus,research on the nexus between coupling internal and external systems,research on the nexus of response measures caused by future uncertainty,and research on transboundary cooperation considered water benefit sharing.We recognize the types,characteristics,and challenges of current quantitative assessment methods,and point out the future development trends from the perspective of actual needs of transboundary basins,i.e.,promoting information sharing and data mining,revealing the coupling and feedback mechanism of the water-energy-food nexus,enhancing the development and application of quantitative assessment model of the water-energy-food nexus,strengthening the researches on future uncertainty of the water-energy-food nexus,and promoting multi-stakeholder cooperation.This review will facilitate the rational development and utilization of water resources in the transboundary river basins and realize deeper international cooperation.
