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.
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 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 Meuse and the Scheldt river basins are subjected to pollution and seasonal water shortages, as well as political clash of interests regarding maritime access. Action was taken to solve these issues by the Belgian government. However, although an agreement was eventually made, political issues made the process complex. From this case, it is apparent that a cross-sectoral approach that looks beyond the water sector is often instrumental in developing attractive package deals.
In the River Basin District of the CEE region, the countries are cooperating to develop transboundary management, using the International River Basin Commission as a platform. The aim is to address national IWRM priorities, strengthen cooperation with major stakeholders and initiate changes in policies and legislation. This case illustrates the difficulties to balance national priorities in a transboundary context.
The Ruzinov Strkovec Lake has been subjected to severe pollution due to contaminated by illegal sewage pipes. The Association of Industry and Nature Protection took action and initiated and organised a project to both revitalise the lake and draw the attention of local people to its flora and fauna. The key lesson learnt is how the partnership between an NGO and municipality can result in a successful revitalisation of local water resources.
In the Danube hydrographic basin, agricultural practices continue to be the main source of water pollution. A pilot project “Best Agricultural Practices” was initiated focusing on e.g. nutrient management, conservation tillage and manure management. Awareness campaigns were initiated, training and education of farmers were emphasised. The key lesson is that these projects should be complimented by other technical and investment measures.
Dniester river basin is a transboundary basin shared by Moldova and Ukraine. Throughout the Soviet era, the water quality deteriorated severely. After the USSR was dissolved, a bilateral agreement was signed by Moldova and Ukraine on the joint use and protection of water resources. This cooperation framework is based on the contributions of network of local authorities. This case illustrates the importance of cooperation among all key stakeholders.
Lake Peipsi/Chudskoe is the largest transboundary lake in Europe. Action has been taken by riparian governments of Russia and Estonia to develop and sign an Agreement on the Protection and Sustainable Use of Transboundary Water Bodies. An intergovernmental commission was established to co-ordinate the implementation of this agreement. Co-operation over Lake Peipsi demonstrates how integrated water resource management tools can be applied to transboundary waters shared by countries in transition.
