Abstract The United States and Mexico have engaged in hydrodiplomacy—a practice of transboundary water management that blends water diplomacy and science diplomacy--for more than 75 years, since the adoption of the Treaty of 1944 and the creation of the International Boundary and Water Commission. We examine six major turning points in U.S.-Mexico hydrodiplomacy to ascertain the key factors in the region’s history of resolving transboundary water issues. We find that recognized adaptive governance indicators—such as social learning, sustained relationships, flexible governance mechanisms, and state and non-state networks are essential elements of hydrodiplomacy. Our research suggests that robust and foundational institutions comprise another key indicator of adaptive governance specifically in transboundary contexts. A commitment to both science and diplomacy have been important components underlying the effectiveness of hydrodiplomacy in the border region. Binational networks involving diverse state and non-state actors at multiple scales have increasingly played a pivotal role in shaping desirable hydrodiplomatic outcomes in the region.

美墨边境的水文外交和适应性治理：跨界水资源管理 75 年的传统与创新

摘要 自从 1944 年条约通过和国际边界和水委员会成立以来，美国和墨西哥从事水外交——一种将水外交和科学外交相结合的跨界水资源管理实践——超过 75 年。 . 我们考察了美墨水文外交的六个主要转折点，以确定该地区解决跨界水问题历史上的关键因素。我们发现公认的适应性治理指标——例如社会学习、持续的关系、灵活的治理机制以及国家和非国家网络是水文外交的基本要素。我们的研究表明，稳健和基础性的机构是适应性治理的另一个关键指标，特别是在跨界背景下。对科学和外交的承诺一直是边境地区水文外交有效性的重要组成部分。涉及多个规模的不同国家和非国家行为者的双边网络在塑造该地区理想的水文外交成果方面发挥着越来越重要的作用。
