水-能源-食品关系(WEFN)作为一种更全面地管理水的方法,已经引起了国际关注。利用水资源综合管理(IWRM)方法取得的进展。然而,模拟水的可用性,能源,食物和它们之间的联系是复杂的,具有主要障碍,包括能够评估WEFN互连系统的数据和建模平台的可用性。已经尝试对每个部门的资源可用性进行建模,但是很少有人尝试在复杂的跨界盆地中考虑WEFN,特别是考虑到可持续发展目标(SDG)。这里,水,能源,粮食供应模型是使用遥感,国家政府报告,和全球数据集。该模型探索了水的物理可用性和生产之间的复杂相互作用,能源,和代表不同州的几个子盆地的食物。结果显示了社会经济发展的潜在影响,人口变化和资源跨界合作。以东南亚马盆地为例的跨界合作,在现有资源和运营下,可以在旱季期间使用流域多余的水电来改善每月的粮食安全并减少煤电运营。这些发现表明,跨界合作改善了能源和食物的获取,同时有可能减少对水的需求。此外,该研究强调了跨界合作可以进一步帮助实现关于负责任的生产和气候行动的可持续发展目标12和13的方式,分别。建模框架易于转移,可以支持其他盆地的类似分析,为全球实现几个可持续发展目标做出贡献。
The Water-Energy-Food Nexus (WEFN) has gained international attention as an approach for managing water more holistically, building on the progress made by the Integrated Water Resources Management (IWRM) approach. However, modelling the availability of water, energy, and food and their interconnections is complex, with major barriers that include the availability of both data and modelling platforms capable of assessing the interconnected systems of the WEFN. There have been attempts to model resource availability in each sector generally, but few attempts to consider the WEFN in complex
transboundary basins, especially considering Sustainable Development Goals (SDGs). Here, a water, energy, and food availability model was developed using a combination of remotely sensed, national government reported, and global datasets. The model explores the complex interactions between the physical availability and production of water, energy, and food for several subbasins representing different states. Results showed the potential impacts of socioeconomic development, population changes and
transboundary cooperation on resources.
Transboundary cooperation in the case study Ma Basin in Southeast Asia, under existing resources and operations could improve monthly food security and reduce coal power operations using excess hydropower in the basin during the dry season. These findings show that
transboundary cooperation improves access to energy and food, whilst potentially reducing demands for water. Furthermore, the research has highlighted ways in which
transboundary cooperation can further assist in attaining SDGs 12 and 13 on responsible production and climate action, respectively. The modelling framework is easily transferable and can support similar analysis in other basins, contributing to global attainment of several SDGs.
