ABSTRACT Data exchange in transboundary waters is fundamental to advance cooperative water management. Nonetheless, the degree to which data are shared is not well understood. To gauge this degree, an assessment framework was developed and applied in 25 international river basins. The framework captures the degree to which a set of data parameters is exchanged among countries. A reasonable proportion of surveyed basins exchange some data, but the breadth of such exchange is often limited, and not regular. This paper highlights where data exchange can be improved and provides guidance on how indicators used in global assessment frameworks can motivate this improvement.

细节决定成败：跨界水域的数据交换

摘要 跨界水域的数据交换是推进水资源合作管理的基础。尽管如此，数据共享的程度尚不清楚。为了衡量这个程度，我们开发了一个评估框架，并在 25 个国际流域中应用。该框架捕捉了一组数据参数在国家之间交换的程度。调查流域有合理比例的数据交换，但交换的广度往往有限，且不规律。本文重点介绍了可以改进数据交换的地方，并就全球评估框架中使用的指标如何推动这种改进提供了指导。
