Transboundary organisations provide a framework for coordinating and facilitating the management of water resources across international boundaries, where there are issues about the management of common (cross-jurisdiction) property resources. Such organisations differ in type and function according to the political context, the water resources challenges, and the cultural features of the area. This Tool discusses the various institutional arrangement for transboundary organisations, lays out their main functions, highlights some best examples of transboundary river basin organisations (TRBOs), and provides a reflection on the key challenges which transboundary organisations face.
The type of agreement underpinning transboundary organisations varies greatly around the world, from ad hoc arrangements, memoranda of understanding, to formal international treaties and agreements. These instruments commonly follow international water law principles (Tool A2.02). Depending on their constituent agreement between riparian states, transboundary water organisations could be grouped into the following types (Hooper and Lloyd, 2011): (1) advisory committees; (2) association; (3) authorities; (4) commissions.
It is clear that the effective functioning of transboundary organisations requires a secure funding base (Tool D2), the political will of governments, the commitment of the partners who create them, and other actors that may be involved in the process. Many donors are keen to financially support the international committees when firm, efficient, and transparent agreements among riparian countries are in place. The financing costs for transboundary organisations may vary significantly depending on the mandate, structure and the level of development of riparian countries (GWP & GEF IW:Learn, 2020).
In 1960s-1980s many transboundary basin organisations were established with support from external sources (Joyce and Granit, 2010), but with few exceptions most of them remained at emerging stages in terms of achievements for transboundary cooperation. Negative factors are low political commitment, poorly defined goals, insufficient mandate and decreasing donor support. There are however numerous exceptions, including Senegal River Development Organisation and Lesotho Highland Development Project, where cooperative efforts produced significant transboundary benefits for energy, bulk water supply and irrigation.
Transboundary water management studies have shown that nowadays most active cooperation appears in the Nile, the Volta and the Mekong river basins due to the strong institutional capacity of transboundary basin organisation. Looking at regional distribution of transboundary river organisations: Africa hosts the highest number of TRBOs (18 organisations), followed by Europe (10), South America (6), Asia (6) and North America (4) (Kim and Glaumann, 2012).
