The purpose of this article is to examine the research advanced in the journal, International Environmental Agreements: Politics, Law and Economics that represents key insights into international agreements on water and their political, legal, economic and cross-disciplinary dimensions for water governance. The article analyses evidence and lessons learnt over the last twenty years to inform policy through a review of theoretical advances, innovations in principles and policy instruments, outcomes of problem-solving and knowledge gained regarding water agreements and associated institutions. Important international agreement principles of no significant harm and economic frames of water as a ‘commons’ advance equity and community of interest in relation to water. The studies on water, sanitation and hygiene point to the ways the role of the state can be advanced in achieving Sustainable Development Goals and in complex contexts of water scarcity and public private partnerships. Cross-disciplinary learnings substantiate the existence and utility of multiple water frames in legal arrangements and use of multiple policy instruments. Cross-disciplinary insights are significant in addressing equity, whether through the nascent development of water indicators or in advancing social learning. Water governance frameworks increasingly focus on adaptation by incorporating multiple stakeholders. These findings that advance equity and inclusivity are tempered by crucial lessons in our understanding of the very contested, power-laden nature of water governance that impact agency at multiple scales and policy coordination across sectors of water, food and energy.

本文的目的是审查《国际环境协议：政治、法律和经济学》期刊中的研究进展，这些研究代表了对国际水协议及其对水治理的政治、法律、经济和跨学科维度的重要见解。本文通过回顾理论进展、原则和政策工具的创新、解决问题的结果以及在水协议和相关机构方面获得的知识，分析了过去 20 年中获得的证据和经验教训，从而为政策提供信息。没有重大损害的重要国际协议原则和作为“公地”的水的经济框架促进了与水有关的公平和利益共同体。关于水的研究，环境卫生和个人卫生指出了在实现可持续发展目标以及在水资源短缺和公私伙伴关系的复杂背景下，可以推进国家作用的方式。跨学科的学习证实了法律安排和使用多种政策工具中多个水框架的存在和效用。跨学科见解对于解决公平问题非常重要，无论是通过水指标的新发展还是在促进社会学习方面。水治理框架通过纳入多个利益相关者，越来越注重适应。这些促进公平和包容性的发现被我们理解非常有争议的关键教训所缓和，
