Reservoirs are built worldwide for a higher water supply in dry periods by storing water temporarily in wet periods. Recent socio‐hydrology studies hypothesized, by creating “supply–demand cycles”, that reservoirs can lead indirectly to counterintuitive dynamics such as more water scarcity and a higher economic and social vulnerability. This opinion argues that reservoirs are part of co‐evolutionary processes with natural, social, and engineered elements and therefore, water scarcity need to be analyzed within socio‐political interactions. Aspects such as (a) institutions; (b) governance processes; (c) social–ecological factors; (d) narratives of water scarcity; and (e) powerful economic interests are essential to understand feedback mechanisms between reservoirs and water scarcity and to hypothesize long‐term phenomena such as water scarcity. Neglecting these interactions could lead to biased research agendas, misleading conclusions, and adverse effects on the transformation process toward sustainability. Given the complexity of social–ecological systems, the diversity and critical capacity of inter‐ and transdisciplinary work is crucial to further advance the study of unintended side effects of reservoirs or — more general — the study of socio‐hydrology.

关于水库在减少缺水中作用的争议性辩论

通过在湿润时期暂时储存水，在世界范围内建造了水库，以在干旱时期增加供水量。通过建立“供需循环”，最近的社会水文学研究假设，水库可以间接导致违反直觉的动态，如水资源短缺和经济和社会脆弱性增加。这种观点认为，水库是自然，社会和工程要素共同进化过程的一部分，因此，需要在社会政治互动中分析水资源短缺的情况。（a）机构等方面；（b）治理程序；（c）社会生态因素；（d）关于缺水的叙述；（e）强大的经济利益对于理解水库和缺水之间的反馈机制以及假设诸如缺水之类的长期现象至关重要。忽视这些相互作用可能会导致研究议程偏颇，产生误导性结论，并对可持续发展的转型过程产生不利影响。鉴于社会生态系统的复杂性，跨学科和跨学科工作的多样性和关键能力对于进一步推进水库非预期副作用的研究，或更广泛地说，对社会水文学的研究至关重要。
