Activities such as horticulture and tourism around the Great Barrier Reef create sediment, nutrient and pesticide runoff, placing increased pressure on the ecosystem. The World Wildlife Fund has taken action, predominantly by raising awareness. The key lesson is how a carefully orchestrated campaign can convince decision-makers of the importance of integrated river basin management as a means of reducing land-based marine pollution.
Unsustainable irrigation policies during the Soviet era have had devastating consequences for the Aral Sea. With the collapse of USSR, the riparian states took action and entered into agreement on Cooperation in the Joint Use and Protection of Water Resources of Interstate Significance. Furthermore, the international community took action and much attention has been devoted to re-establish the Aral Sea ecosystem. This case illustrates the importance of engaging all key stakeholders.
Oil-shale mining and oil-shale based electricity production has caused serious damage to ground and surface water in the Viru-Peipsi catchment area in Estonia. Action was taken to enhance the protection of the water resources through a project that set out a management plan. The project included data collection, monitoring and capacity building. Due to the success of this project, it can be used as an example for future developments.
After some devastating floods in the Yangtze, the Chinese government took action and issued a policy to counter floods, including wetland restoration. WWF further assisted and developed four pilot sites to demonstrate the benefits of wetland restoration for biodiversity, and to seek alternative income options for farmers, based on the sustainable use of wetlands. This case illustrates the value of a participatory approach.
In Ukraine, reforms in the sector of water supply and sanitation have focused on centralising water supply and sanitation. Efforts have been made to decentralise water management, delegate to local authorities as well as increase supply in rural areas. This has been done through awareness campaigns, capacity building and innovative techniques of wastewater reuse. The key lesson learnt from this case is that IWRM principles need to be considered when planning for water infrastructure.
The Lempa River is shared by Guatemala, El Salvador and Honduras, making its management a good example of transboundary cooperation. To reach consensus, action was taken to develop a treaty as part of a regional process. However, since the treaty was not accompanied by strategies designed by local actors, it is somewhat weak. Nonetheless, this case illustrates that political willingness is crucial for advancing towards IWRM in transboundary watersheds.
El Salvador has experienced an increased vulnerability due to Climate Change. To tackle the challenges, an Early Warning System has been installed. This is part of the strategy of the local government to reduce the vulnerability and develop the capacity of the area to deal with floods and landslides. One lesson learnt is that political stability in an area is a great asset when carrying out any political reform.
The Cuero River area is particularly susceptible to floods, making the communities living in the surrounding area vulnerable. This area was consequently chosen for implementation of an Early Warning System Project. Action was taken in three separate phases in three different areas. From the experience, the lesson learnt is that more effort should be devoted to training of a leader group that can promote and consolidate the system’s self-sufficiency.
Scientific and estuarine research on the Chesapeake Bay pinpointed several areas that required attention including nutrient over-enrichment, dwindling underwater Bay grasses, and toxic pollution. Action was taken and the Chesapeake Bay Commission was established to address the issues. This case illustrates how the use of modelling can be a cost-effective tool in helping to implement watershed restoration actions and monitor goals set by stakeholders.
In the River Basin District of the CEE region, the countries are cooperating to develop transboundary management, using the International River Basin Commission as a platform. The aim is to address national IWRM priorities, strengthen cooperation with major stakeholders and initiate changes in policies and legislation. This case illustrates the difficulties to balance national priorities in a transboundary context.
