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.
Wathersheds of Tacana originate on the volcano, with both shared by Guatemala and Mexico. This region is of great strategic importance for both countries since they supply water to a large number of residents in the cities located downstream and are the main source of irrigation water for agriculture. In the lower reaches, fishing is an important source of income.
The area of Zarati river sub basin belongs to important water recharge zones. There is, however, a need to restore the area, which has been susceptible to degradation. Action has been taken in a bottom-up manner, applying Participatory Rural Assessment. Important lessons can be drawn from this in terms of IWRM, as it sets a clear example of active participation of the communities and the local authorities.
The Prespa basin was affected by over-abstraction and diversion of water, wetland drainage, deforestation and overgrazing, leading to danger for human livelihoods and ecosystems. Action was taken by WWF through the creation of the Society for the Protection of Prespa, eventually culminating in the creation of Prespa National Park. The lesson drawn is that to change the perspective of local stakeholders to ensure that they share a common vision is vital for success.
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.
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 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 Danube region is characterised by long-term cooperation. One of the most important agreements is the Danube River Protection Convention, aiming to achieve sustainable and equitable water management. To achieve this, the Danubian countries have taken appropriate legal, administrative and technical measures to at least maintain and improve the ecological and water quality conditions. The main lesson learnt is that strong cooperation among all the involved parties is required.
