The EU Water Framework Directive requires all EU member states to achieve satisfactory water quality of all waters by 2015. Although each country is individually responsible, cooperation over transnational water resources is required. In the Körös/Crisuri river basin, a project was initiated using the expertise and experience of Hungary and Romania, involving all key stakeholders. The key lesson is the importance of public participation.
The water resources of Brazil are subjected to pollution and mismanagement. Furthermore, it is susceptible to urban flooding and land-slides. To address these issues, action was taken to increase funding to the National Water Agency. In terms of IWRM, the key lesson learnt is the need for strong and well-funded executive agencies capable of putting laws into practice.
The lowland valley of Chancay-Lambayeque watershed is scarce of water resources, forcing farmers to irrigate with insufficiently treated waste water, resulting in severe health issues. Action was taken through the project “Future Development of San José farmer community: Wastewater” which was a collaboration between the private and the public sectors, aiming to illustrate alternative ways to irrigate. The most important lesson is that cooperation is an important instrument for development.
In Kazakhstan, the issue is not one of scarcity but of management, a problem that can be solved through applying the principles of IWRM. The government of Kazakhstan consequently initiated a water resources management project aiming at strengthening water management organisations and by instituting the practice of IWRM. In this process, training, workshops and dialogues both within and outside the water sector are crucial.
The Municipality of Talcahuano because of rapid urbanisation is subjected to natural resource degradation. Action was taken and a municipal strategy was created, assigning the municipality as the institution in charge of administering and combating natural resource degradation. This case illustrates the appropriateness of the municipal level of government in successfully addressing the recovery of water resources and environmental management.
There were concerns that Lake Arenal in Northern Costa Rica was threatened due to problems of deforestation and possible premature sedimentation, leading the government to take action, resulting in successful national and local benefits in terms of energy produced and area irrigated. The most important lesson learned is the importance of consulting all parties involved before initiating the project to achieve the best result.
The lack of laws and regulations, as well as good administration and management, contribute to poor water governance. In the Naranjo river basin, action was taken to implement IWRM after initiatives stemming from individuals with personal conviction of its importance. This has led to the creation of some formal legislation and the process of implementing IWRM. This consequently illustrates the potential important role of individuals in driving policy change.
In Costa Rica, action was taken to introduce water pricing to pay for services provided by forests in watershed areas. As a result, Costa Rica’s watershed owners are beginning to be rewarded for providing water, whether for drinking or for generating electricity. The main lesson is that initiatives that ensure local groups are included in the benefits of conservation are needed to involve them in helping to protect the water catchment areas.
The Reventazon River Basin has been subjected to severe degradation, mainly through water pollution, leading to proliferation of disease, increased cost of drinking water, and endangered biodiversity. Action was taken by establishing the Committee for the Management and Planning of the Reventazon River Basin working with conservation and land management. The key lesson for success is the importance of the coordination of the different actors that deal with the basin management.
Rural and peri-urban areas are often neglected when making infrastructure investments. However, these areas could gain from treatment of domestic wastewater through the construction of wetlands. In Bulgaria, the problem of wastewater treatment was addressed through the construction of a wetland for treating wastewater from domestic sources. The lesson learnt is the importance of community initiatives.
