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.
In order to meet new demands, the Jordan Valley Authority was in need for reform. Action was taken to initiate a public strategic planning process led by a steering committee composed of all relevant stakeholders and various working groups. The case consequently illustrates how an integrated strategic planning process can create conditions under which all stakeholders can be involved in the proposed institutional reform.
Egypt’s water resources are severely constrained. This calls for increasing the water use efficiency by improving irrigation management practice, as the agriculture sector is the main user of water resources. To address the issue, an Irrigation Improvement Programme was initiated, including a combination of technical changes and infrastructure investment. The case clearly demonstrates the importance of building appropriate institutional structures in parallel to the introduction of technical changes.
Due to the growing build-up area and changing land use in the Veluwe nature conservation area, the old water management infrastructure no longer coped. Action was thus taken and the traditional technical solution was replaced by a new integrated approach, which combines nature and landscape conservancy with modern water management. This case highlights the importance of utilising inhabitants’ knowledge when drafting new projects.
Climate change is expected to severely affect water resources in the low-lying part of the Netherlands. It was decided to take an integrated approach and a process was set up in which all parties claiming space in the area were invited to discuss the water issues. The key insight from this case is the additional water needs can be integrated in the spatial planning through an open planning process.
The Veluwe Randmeren lakes in the Netherlands were negatively affected by the discharge of phosphates and nitrates from agriculture and household use. Furthermore, increase in population pressure posed further challenges. To address these issues, a group consisting of national and local authorities undertook a project, which gradually increased the water quality. The case study demonstrates the importance of allowing integration among stakeholder groups.
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.
