在未来气候和社会经济变化下，全面的水管理办法至关重要，特别是在努力实现清洁水、消除饥饿、清洁能源和陆地生活等可持续发展目标等跨学科社会目标的同时。在水--食物--能源--环境相互联系的办法中评估水资源，使与水有关的部门之间的关系得以理顺，同时纳入社会变化的影响。我们使用系统建模的方法来探索21世纪中叶在印度西喜马拉雅复杂的水资源系统中全球变化对纽带的影响，考虑到一系列气候变化和替代社会经济发展情景。结果表明，与气候变化相比，未来的社会经济变化将对纽带产生更大的影响。水力发电和环境保护是在所研究的系统中适应的主要机会和限制，因此应成为追求可持续发展目标的行动和系统变革的重点。具体情景的协同作用的出现和各联系组成部分指标之间的取舍表明，水资源系统模型可为设计更好地应对与未来全球变化有关的复杂联系挑战提供益处。
Holistic water management approaches are essential under future climate and socio-economic changes, especially while trying to achieve inter-disciplinary societal goals such as the Sustainable Development Goals (SDGs) of clean water, hunger eradication, clean energy and life on land. Assessing water resources within a water-food-energy-environment nexus approach enables the relationships between water-related sectors to be untangled while incorporating impacts of societal changes. We use a systems modelling approach to explore global change impacts on the nexus in the mid-21st century in a complex western Himalayan water resource system in India, considering a range of climate change and alternative socio-economic development scenarios. Results show that future socio-economic changes will have a much stronger impact on the nexus compared to climate change. Hydropower generation and environmental protection represent the major opportunities and limitations for adaptation in the studied system and should, thereby, be the focus for actions and systemic transformations in pursue of the SDGs. The emergence of scenario-specific synergies and trade-offs between nexus component indicators demonstrates the benefits that water resource systems models can make to designing better responses to the complex nexus challenges associated with future global change.
