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.
China is faced with significant costs regarding floods and degradation of ecological conditions in the Yangtze River basin. As a response, the application of Ecosystem Function Conservation Areas approach has been initiated not only to increase water retention capacity and reduce sediment loads, but also to provide benefits in biodiversity, carbon sequestration and sustainable land management. The key lesson is that success is easier to achieve with positive natural and political conditions.
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.
With one of the lowest per capita freshwater resources in the world, China have been investing in and seeking new ideas and methods for improving both supply side and demand side management of water resources. This has included numerous experiments in “eco-compensation”. These experiences demonstrate that eco-compensation should be considered as a potential tool for Integrated River Basin Management to address financing shortfalls, identify management pitfalls, and convince key stakeholders to participate.
The Yangtze River Basin has been severely affected by climate change. To address this, the Yangtze River Basin Climate Change Vulnerability and Adaptation Report has been drafted to evaluate the impact on representative ecosystems and water resources, and pinpoint adaptation strategies. The experience has demonstrated that good adaptation measures should consider not only climate itself, but also other factors, such as economy, technology, as well as social and cultural norms.
The Weihe River plays a central role in Shaanxi. However, rapid economic development has created many problems, including increased water scarcity, pollution and regional ecological environment deterioration. As a response, the Weihe River Basin Integrated Management Plan was developed based on the principles and approaches of IWRM, with the participation of many sectors. The significance of this case is the promotion of public participation and gradual improvement of the market economy system.
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.
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.
