In the village of Parakar, untreated wastewater contaminated agricultural lands, jeopardised food safety and posed severe health risks. In 2010, the Parakar community supported by partners from the Country Water Partnerships of Armenia initiated and developed a demonstration pilot project for domestic wastewater treatment. Particular attention was given to community involvement. This case illustrates the value of small scale solutions.
Due to substantial population growth putting increased pressure on the water resources, their quality has started to deteriorate. This is perceived as a serious issue since water is inseparably linked with the socio, economical and cultural aspects of livelihoods. Action was taken through an integrated lake conservation programme, aiming to improve water quality. The most important lesson learnt is that awareness raising, education and stakeholder participation are essential.
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.
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.
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 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.
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.
