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 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.
Large scale projects in Slovakia caused negative effects in terms of biodiversity losses and reduced floodplain ecosystem functions. To combat this, a project “Integration of Ecosystem Management Principles and Practices into Land and water Management” of Laborec-Uh region was initiated. This case illustrates the importance of accounting for both biodiversity and economic returns when developing projects.
Guizhou already experiences the effects of climate change, including droughts. Action was taken with the approval of a new policy document which provides funds supporting water quality improvements, water and soil conservation, ecosystem rehabilitation, irrigation, and managing increasing demand. Steps have also been taken for preventive actions for subsequent droughts. The most important lesson that can be learnt is that the greatest challenge to building resilience to droughts is institutional.
Clearing for logging, combined with expanding agriculture and palm oil plantations has led to increased flooding, and pollution of the Kinabatangan River due to pesticides and fertilizers. Working in partnership, the Sabah Wildlife Department and the WWF took action and have established the Lower Kinabatangan Wildlife Sanctuary. The key lesson of this case is the value of starting with small-scale feasible projects before scaling up.
With the collapse of the USSR, the water sector seized to be subsidised leading to deterioration of basic infrastructure. Action was taken to partially transfer the responsibility for operation and maintenance of irrigation systems to water users. Nonetheless, this has had limited success because it has been seen as an additional cost rather than benefit. This illustrates that for this to work, the returned benefits need to be higher than the costs.
Uzbekistan is experiencing water scarcity, an issue which will be exacerbated with increased demand. Although policies exist, the water seldom reaches the end water users. To combat this issue, action has been taken by GWP Uzbekistan to conduct trainings and workshops on the dissemination of IWRM to encourage a participatory multi-sector approach. This case study illustrates the importance of public awareness, and the need for work to be conducted at all levels.
In Chile, water has been privatised. However, in order to make sure that access was still available to all strata of society, the privatisation was accompanied by a robust regulatory framework, including a system of direct subsidies for drinking water consumption and sewage services for low income households. This case thus illustrates that in case of privatisation, a direct subsidiary scheme should be considered.
The Toledo River basin is increasingly contaminated due to unsustainable agricultural practices, Action was taken through a UNESCO-IHP project aiming to perform an integrated environmental assessment of agricultural and farming production systems located in the Toledo River Basin. By using a multi-criteria approach, it was possible to highlight the interactions and use of natural capital, human-driven resources, and ecosystem services supporting agricultural and farming production systems.
