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.
In Romania, water is subjected to deteriorating quality. In rural areas, 70% of the population depend on small scale water supply systems, which are often exposed to human and animal manure. To combat this, the project Safe Sanitation, Health and Dignity was initiated. This project shows that programmes could connect local communities, regional and national authorities, and contribute to the realisation of the allocated targets of the protocol of water and health.
The Maltese islands experience acute water shortage as an area. To address this, leakage control has been developed to become a strategically important component for water resource management, and has been used to reach an optimum economic balance between water supply and water demand. The key lesson is that leakage management is an effective supply side action to increase efficiency in water use leading, and can be used as a strategic tool.
The quality of groundwater recharging the Guarani aquifer is threatened in some areas by rapid land-use changes, and locally by rapid urbanisation. Action was taken by the World Bank through a GEF-funded project on the ‘Sustainable Development & Environmental Protection of the Guarani Aquifer’, which included scientific studies, institutional provisions and transboundary groundwater management. This case study reinforces the lesson to ‘think globally but act locally’.
The Municipality of Talcahuano because of rapid urbanisation is subjected to natural resource degradation. Action was taken and a municipal strategy was created, assigning the municipality as the institution in charge of administering and combating natural resource degradation. This case illustrates the appropriateness of the municipal level of government in successfully addressing the recovery of water resources and environmental management.
Rural and peri-urban areas are often neglected when making infrastructure investments. However, these areas could gain from treatment of domestic wastewater through the construction of wetlands. In Bulgaria, the problem of wastewater treatment was addressed through the construction of a wetland for treating wastewater from domestic sources. The lesson learnt is the importance of community initiatives.
The Kumbo water supply system has always had contested ownership claims. After decades of protest, action was taken and management was transferred to Kumbo Urban Council, resulting in the establishment of an inclusive and participatory community water governance structure. From this, the lesson can be learnt that the command and control paradigm can provoke social and political instability. The case also demonstrates how community based platforms can enhance community mobilisation and participatory governance.
