In Slovenia, water is extracted for drinking water, energy, fish-farming, irrigation and technological purposes. In order to avoid over-extraction, an Environmental Flow framework has been implemented, assessing within what limits water can be extracted, using hydromorphological, hydrological, hydraulic and ecological criteria. The case shows that it is important to combine policy decisions with expert evaluations.
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 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.
Irrigation infrastructure is crucial for economic development in Fujian. However, due to incomplete water management, the existing water facilities do not satisfy the current development. Action has been taken by the infrastructure department of Fujian provinces to cooperate with local farmers and organisations to explore participatory management and new mechanism of local water management. This case indicates that direct involvement of water users will result in rational use of water resources.
Hebei has only met water demand through overdraft of deep groundwater, resulting in the formation of a groundwater overdraft depression. This issue is further exacerbated by saline water intrusion into the groundwater tables. The water administrative department has taken measures accounting for IWRM principles, for example by establishing the Water Users Association to encourage participatory management. The lesson learnt is the value of a participatory approach in management.
The Eastern area of Tucuman province was faced with significant problems of contaminated water. Extensive research was done, involving universities, and a project was carried out, applying the aspects of IWRM within the areas of technical solutions, institutional arrangements of future water supply operation. This case study highlights the importance of conducting research prior to a project to attain sufficient information.
In Marocco, rapid urbanisation has led to increased demands for quality and quantity of water resources. To meet the challenges posed by the growing water scarcity, Morocco has adopted an integrated approach to water resources management through mutually reinforcing policy and institutional reforms, including the adoption of a long term IWRM strategy. The key lesson is the importance of introducing economic incentives to water management.
To implement policy change is a process that takes time. During this time, it is possible that the people involved change, resulting in a loss of knowledge. In Malawi, action was taken to combat institutional memory loss by involving as many high-level decision-makers as possible and by organising awareness raising workshops. This demonstrates that it is possible to avoid the loss of knowledge when key decision and policy-makers change.
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.
