For centuries the Upper Guadiana Basin has been irrigated with groundwater, resulting in a drop in the water table of more than 20 meters. Actions were taken to address this issue, including regulations restricting aquifer abstraction and economic incentives to encourage farmers to improve irrigation efficiency and plant alternative crops. The key lesson learnt is that surface and underground waters cannot be managed separately.
The Upper Guadiana Basin provides a classic example of conflict caused by the intensive use of water resources in a semiarid region. Since the 1960s, uncontrolled abstraction of groundwater to provide water for crop irrigation in the area has lowered the water table in places by up to 50m, causing the main river channels to run dry and some wetlands to become desiccated. On the other hand, the abstraction has also supported a booming agricultural economy.
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.
The EU Water Framework Directive requires measures to achieve good status of all waters by 2015. In Germany, it is not the federal government that is in charge of implementation but it is the responsibility of the county. To meet the objective, transboundary exchange of experiences was promoted by broadening the range of methods and tools available to water managers. From this study, it is evident that interaction with stakeholders plays a central role.
The EU Water Framework Directive requires measures to achieve good status of all waters by 2015. In France, water management is planned at basin-level by state offices and water agencies, but measures are implemented by the local authorities. To meet these requirements, the i-Five project was launched, applying an action research methodology to selected areas. From this study, it is evident that interaction with stakeholders plays a central role.
Climate Change is expected to have severe impacts on river discharges and water quality and quantity. In an effort to proactively find solutions to the current and future challenges of water, the project Environmental state and sustainable management of Hungarian-Slovakian transboundary groundwater bodies was initiated. The key lesson is the importance of evaluating all resources, including the links between groundwater and surface water.
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.
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 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.
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.
