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.
Irrigation infrastructure is crucial for economic development in Fujian. However, due to incomplete water management, the existing water facilities do not satisfy the current development. Action has been taken by the infrastructure department of Fujian provinces to cooperate with local farmers and organisations to explore participatory management and new mechanism of local water management. This case indicates that direct involvement of water users will result in rational use of water resources.
Water Supply and Sanitation policy in Vietnam is regulated through policy and a regulatory framework. However, the rural sanitation sector have had limited success and management has failed to be scaled up. To address these issues the Problem-Driven Governance and Political Economy Analysis Good Practice Framework was used to analyse the poor performance. The most important lesson is that not all policies are appropriate for scaling up.
Half of the land area of Tien Giang Province in Vietnam is exposed to annual floods and the other half to saline intrusion. Action was taken to formulate the National RWSS Strategy and efforts were made to make local communities aware of methods and approaches in harvesting water and well drilling that are cost effective and sustainable in their development. The key lesson is the value of appropriate planning prior to any project.
