Lake Peipsi/Chudskoe is the largest transboundary lake in Europe. Action has been taken by riparian governments of Russia and Estonia to develop and sign an Agreement on the Protection and Sustainable Use of Transboundary Water Bodies. An intergovernmental commission was established to co-ordinate the implementation of this agreement. Co-operation over Lake Peipsi demonstrates how integrated water resource management tools can be applied to transboundary waters shared by countries in transition.
In preparation for the new Water Law in Bulgaria, as well as the EU Water Framework Directive, the watershed council was set up as a pilot to test on-site effective and participatory approaches to river resource management in the Varbitsa River. The key lesson drawn is that participatory, open, citizen-friendly and bottom-up approaches are more efficient than top-down administrative approaches.
The Tsurumi River Basin, located in the suburbs of Tokyo, extends over an area of 235 km2 and a river length of 42.5km. The Tsurumi River Basin is regarded as one of the most important and representative river basins in Japan. The basin was largely developed by the rapid urbanization since the 1960s.
The Murray-Darling Basin was subjected to widespread environmental degradation. In response to this problem, the Murray-Darling Basin Commission was established in January 1988 under the Murray-Darling Basin Agreement, focusing on protecting and improving water quality. The key lesson is that the participatory approach used with its Community Advisory Committee has helped the Commission to be successful in winning and maintaining community interest, involvement and support.
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.
In Australia, a new approach to water management was needed to allow imported water to be used for irrigation without increasing the salinity of the soils or groundwater. Action was taken to develop a framework to enable irrigators to identify and to manage the environmental risks associated with the use of River Murray water for irrigation. The key lesson is that a salt management strategy is relevant wherever there are plans to irrigate land.
Australia implemented a series of reforms to the water sector in the State of Queensland, including the use of a ‘whole of river basin’ strategic plan approach within which local resource operation plans are prepared and implemented. The key lesson learnt is that an incremental approach, with water planning developing in “bite-sized chunks” allowed government to be flexible in response to changing circumstances.
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.
Rapid urbanisation has led to widespread settlements of floodplains, resulting in widespread vulnerability of livelihoods. Since traditional approaches are no longer sufficient, a more integrated flood management approach was realised to adapt to changing social, hydrological, and environmental conditions along the nation’s major waterways. Furthermore, the Ministry of Water Resources prepared a national flood management strategy. The crucial lesson is that the key to flood risk management is learning to live with flood risks.
Hebei has only met water demand through overdraft of deep groundwater, resulting in the formation of a groundwater overdraft depression. This issue is further exacerbated by saline water intrusion into the groundwater tables. The water administrative department has taken measures accounting for IWRM principles, for example by establishing the Water Users Association to encourage participatory management. The lesson learnt is the value of a participatory approach in management.
