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.
The area of Zarati river sub basin belongs to important water recharge zones. There is, however, a need to restore the area, which has been susceptible to degradation. Action has been taken in a bottom-up manner, applying Participatory Rural Assessment. Important lessons can be drawn from this in terms of IWRM, as it sets a clear example of active participation of the communities and the local authorities.
The San Juan River waters have experienced deterioration due to poor management of its basin. To address the issues, action has been taken to implement IWRM to address the areas of water, soil, forests and municipal development in a cross-sectoral manner. This case study is a good reminder of the integrated nature of IWRM, and the importance of a model that accounts for management of both water and land.
The area around Lake Moyua is experiencing severe soil degradation resulting from inappropriate agricultural practices. To reverse and control the degradation process, an IWRM Plan is implemented. By involving the communities, the aim is to restore the soil, the hydrological systems, forests and biodiversity, as well as the harmonisation of policies and implementation of management regulations. This case study consequently demonstrates the value of a bottom-up approach.
The Prespa basin was affected by over-abstraction and diversion of water, wetland drainage, deforestation and overgrazing, leading to danger for human livelihoods and ecosystems. Action was taken by WWF through the creation of the Society for the Protection of Prespa, eventually culminating in the creation of Prespa National Park. The lesson drawn is that to change the perspective of local stakeholders to ensure that they share a common vision is vital for success.
The Maltese islands experience acute water shortage as an area. To address this, leakage control has been developed to become a strategically important component for water resource management, and has been used to reach an optimum economic balance between water supply and water demand. The key lesson is that leakage management is an effective supply side action to increase efficiency in water use leading, and can be used as a strategic tool.
