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.
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.
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.
Astien groundwater aquifer has been subjected to over-use due to good water quality and over-extraction. To address this, SMETA, a syndicate of local authorities, was established to organise the management of the aquifer. Key lesson learnt is that an organisation like SMETA can prove to be a successful forum for groundwater protection.
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.
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 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.
