The FHI was originally tested and refined in two key basins in Asia: the Dongjiang River in China’s Pearl River basin and the Lower Mekong in Laos, Thailand, Cambodia and Vietnam. A set of globally-representative basins are in the process of being assessed, taking into consideration different levels of data availability, development trajectories and climatic contexts. Reports will be shared here as they are finalized.
Dongjiang River Basin
The Dongjiang River is one of the main tributaries of the Pearl River system in southern China. It is the primary water source for more than 40 million people, including the city of Hong Kong, which is located outside of the basin but receives about 80% of its municipal water supply from the Dongjiang. Since in the late 1950s, demands on the have Dongjiang increased as dams were constructed for flood control and hydropower. At present, water allocation among the cities and water quality are some of the region’s top concerns.
Sekong, Sesan and Srepok (3S) Basin in the Lower Mekong
Supporting a population of about 3.4 million people, the Sekong, Sesan and Srepok (3S) Rivers form an important sub-catchment of the Lower Mekong and represent a microcosm of the challenges faced by the entire Mekong River basin. Covering just 10% of the Mekong Basin, the 3S rivers provide almost a quarter of the Mekong’s total discharge and nearly 15% of the river’s suspended sediment — which, in turn, provides nutrients to the Tonle Sap Lake and inland fishery as well as the Mekong Delta, Vietnam’s rice bowl. More than 65 dams in the 3S, most for electricity generation, impact seasonal flows, sediment transport and fish migration.

3S Basin Executive Summary
Bogotá Conservation Corridor, Bogotá, Colombia
Located outside of Bogotá, Colombia, the Chingaza-Sumapaz-Guerrero-Guacheneque Conservation Corridor covers 606,297 hectares and includes 22 municipalities. The area is made up of urban and industrial areas (6.2%), agricultural areas (45.3%) and natural and semi-natural forests and páramos (48.5%). It includes the national parks of Chingaza and Sumapaz and is considered the largest example of intact wasteland in the world. The greatest threats to the landscape and biodiversity include desertification, floods and forest fires, all exacerbated by climate change. Additional threats include illegal mining, livestock grazing, urban growth and monoculture agriculture.

Guandú Basin, Brazil
The Guandú River basin is fundamentally important for the metropolitan region of Rio de Janeiro, Brazil. With a drainage area of 1,921 km2, the basin covers 12 municipalities, supplies water to more than 10 million people and various productive sectors, and supports the operation of hydroelectric and thermoelectric plants that generate employment and income for thousands of citizens. Much of the basin has been degraded, even as demands on water use have increased.

Alto Mayo Basin, Peru
The Alto Mayo basinin Peru covers ~780,718 hectares and is shared by three provinces (Rioja, Moyobama and Rodríguez Mendoza) and two regions (San Martín and Amazonas). It contains the Alto Mayo protected forest, whose biodiversity and ecosystems provide important benefits to people. The basin is home to 266,896 people, including 14 indigenous communities, which represent 19.8% of the territory and ~ 2% of the overall population. Although small in number, indigenous groups rely heavily on their natural environment for subsistence needs. It is necessary to incorporate indigenous populations in watershed management processes and to promote policies and planning tools that will allow them to satisfy their subsistence needs.
