Over 100 participants from 22 countries across the Mediterranean attended the recent launch of a joint GWP/OECD project on water governance and financing in the Mediterranean.
The Goascoran River basin is shared by Honduras and El Salvador and is of great environmental, economical and geopolitical importance. In 2006, action was taken to create a multi-sector instance to integrate, influence and coordinate sustainable management of the shared basin. This experience is of great value for IWRM, as the management group establishes a model of work for transboundary management.
Wathersheds of Tacana originate on the volcano, with both shared by Guatemala and Mexico. This region is of great strategic importance for both countries since they supply water to a large number of residents in the cities located downstream and are the main source of irrigation water for agriculture. In the lower reaches, fishing is an important source of income.
The Lempa River is shared by Guatemala, El Salvador and Honduras, making its management a good example of transboundary cooperation. To reach consensus, action was taken to develop a treaty as part of a regional process. However, since the treaty was not accompanied by strategies designed by local actors, it is somewhat weak. Nonetheless, this case illustrates that political willingness is crucial for advancing towards IWRM in transboundary watersheds.
To protect the Panama Canal Watershed, which was created when the Panama Canal was constructed, formal limits to its utilisation was set up, including the Panama Canal Treaty and the creation of a Panama Canal Authority. This case study predominantly illustrates the peculiar problems that arise when a highly artificial watershed is managed by a modern, internationally oriented public corporation with a country that is still copping with the hydraulic culture and a national water policy.
