User manual:

The user manual provides guidelines for carrying out a Freshwater Health Index assessment. It explains the conceptual underpinnings of the Index and provides definitions of the indicators that it encompasses. It also provides guidance for evaluating each indicator, suggestions on data sources helpful to evaluate indicators (for baseline assessments and scenario planning), aggregation of indicators and interpretation of index values. These guidelines will be reviewed and updated periodically, and input from all users of the Freshwater Health Index is welcome.

Basin Assessment Reports:

Dongjiang, China

Located in southern China, the Dongjiang is the smallest of three main rivers comprising the Pearl River system (in terms of both area and annual average discharge), but it is the primary water source for more than 40 million people, including the world’s largest urban agglomeration. Stakeholders in the basin are addressing multiple — and often conflicting — freshwater needs.

Sekong, Sesan and Srepok (3S), Lower Mekong, Southeast Asia

The 3S basin comprises the catchments of the Sekong, Sesan and Srepok Rivers in Cambodia, Lao PDR and Vietnam. The three rivers account for nearly a quarter of the Mekong River’s total discharge and support a population of approximately 3.4 million people. Sixty- five dams have been constructed in the basin to provide water for irrigation and hydropower, and many more are under construction or being planned. The 3S is an important source of nutrients that drives the world’s largest inland fishery and replenishes the important rice growing region in Vietnam. The transboundary nature of the 3S makes resource management a significant challenge, and it provides an opportunity to improve regional dialogue.
