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.
To supply water to a growing population, an aqueduct was built in the watershed of El Limón River in Tovar municipality. However, this aqueduct does not provide sufficient supply, creating conflicts among the communities. To solve these, agreements on the use and conservation of water resources have been made among the communities, involving both rural villages and urban areas. This illustrates the benefits of a participatory approach.
In Carabobo State, the urban and agricultural expansions are the main causes of watershed problems resulting from degradation of forests, deforestation and inadequate solid waste management. Since 2009, action has been taken to combat these developments through participatory public policies which focus on environmental education and sustainable development. The key to the success of the project has been extensive capacity building in combination with concrete management tools.
The Pantanoso watershed in Montevideo has been identified as vulnerable to threats of intense rains and floods, posing risks to the human settlements. To combat the risks, action was taken by the local population and governmental authorities to engage in a project on Climate Related Disaster Risk Management. The key lesson is that strengthening vulnerable communities upon climate risks represents a key tool for the IWRM, since it contributes to empowering the population.
In Chile, water has been privatised. However, in order to make sure that access was still available to all strata of society, the privatisation was accompanied by a robust regulatory framework, including a system of direct subsidies for drinking water consumption and sewage services for low income households. This case thus illustrates that in case of privatisation, a direct subsidiary scheme should be considered.
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.
The Toledo River basin is increasingly contaminated due to unsustainable agricultural practices, Action was taken through a UNESCO-IHP project aiming to perform an integrated environmental assessment of agricultural and farming production systems located in the Toledo River Basin. By using a multi-criteria approach, it was possible to highlight the interactions and use of natural capital, human-driven resources, and ecosystem services supporting agricultural and farming production systems.
A large proportion of Brazil’s population is lacking access to water and sanitation, and development is slow, in particular in rural areas due to lack of funds and political will, but also due to inefficiency in the resources allocation. Action has been taken by the State of Ceará to implement the model called Integrated Rural Water Supply and Sanitation System, illustrating that the most important component of attaining sustainable management is user participation.
The Eastern area of Tucuman province was faced with significant problems of contaminated water. Extensive research was done, involving universities, and a project was carried out, applying the aspects of IWRM within the areas of technical solutions, institutional arrangements of future water supply operation. This case study highlights the importance of conducting research prior to a project to attain sufficient information.
The Lake Atitlán basin experiences serious problems of water pollution, soil erosion and forest and biodiversity losses. Action was taken to establish the Authority for the Sustainable Management of the Atitlán Basin. However, barriers such as lack of public participation, institutional coordination and investment funds have only ensured limited success. The key lesson learnt is that the main barriers to an integrated management of water resources in the basin are strongly interlinked.
