The Bodrog River Basin is exposed to severe flooding caused by jumbled urbanisation and low connectivity between land (agriculture and forestry), urban and water planning. Management is made more complex by the transboundary nature of the basin. A project was, however initiated to strengthen cooperative management and to mitigate consequences of floods through achieving consistent and holistic management of flood risk in three basin countries. This case illustrates the importance of transboundary flood management.
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.
There are growing concerns about the potential effects of climate change on the socio-economic characteristics and natural resources of the Lower Mekong Basin. In response to the potential impacts of climate change, the Mekong River Commission has launched the regional Climate Change and Adaptation Initiative. Furthermore, a Vulnerability and Adaptation Assessment has been conducted. The most important lesson learnt is that it is essential to establish a regional organisation to combat climate change.
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.
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.
Körös/Crisuri transboundary River Basin is in need of more transboundary cooperation and coordination to ensure sustainable management of the resource. To address this, Romania and Hungary jointly developed a strategy for integrated water resources management, aiming to strengthen cooperation. The key lesson is that access to, and management of data is at the core of decision-making in the case of transboundary water management.
The EU Water Framework Directive requires all EU member states to achieve satisfactory water quality of all waters by 2015. Although each country is individually responsible, cooperation over transnational water resources is required. In the Körös/Crisuri river basin, a project was initiated using the expertise and experience of Hungary and Romania, involving all key stakeholders. The key lesson is the importance of public participation.
The Upper Tisza basin requires international cooperation for its management, recognised through bilateral agreements. To further improve management, action was taken to develop a complex joint flood and water management development plan. This project is being implemented in several stages, ranging from elaboration of methods, description of ecological status to the establishment of environmental objectives to improve the current status. The key lesson is the value of bilateral effort in water management.
The Danube region is characterised by long-term cooperation. One of the most important agreements was the Danube River Protection Convention, created with an intention of intensifying cooperation in the field of water protection and water use between countries in the Danube basin. Under auspices of this convention, the Joint Danube Survey was launched. This case demonstrates the importance of collecting data to assess how to move forward with any project.
The Tisza River is faced with deteriorating water quality as well as floods with increasing frequency and levels. These issues are exacerbated by climate change. Action has been taken, both by national authorities, international actors and NGOs to develop more adaptive management schemes. The key lesson is that in water management, the biggest problem is the weak coordination among different fields and interests – such as agriculture, nature, navigation, flood defence.
