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.
Scientific and estuarine research on the Chesapeake Bay pinpointed several areas that required attention including nutrient over-enrichment, dwindling underwater Bay grasses, and toxic pollution. Action was taken and the Chesapeake Bay Commission was established to address the issues. This case illustrates how the use of modelling can be a cost-effective tool in helping to implement watershed restoration actions and monitor goals set by stakeholders.
The Cuero River area is particularly susceptible to floods, making the communities living in the surrounding area vulnerable. This area was consequently chosen for implementation of an Early Warning System Project. Action was taken in three separate phases in three different areas. From the experience, the lesson learnt is that more effort should be devoted to training of a leader group that can promote and consolidate the system’s self-sufficiency.
The lack of laws and regulations, as well as good administration and management, contribute to poor water governance. In the Naranjo river basin, action was taken to implement IWRM after initiatives stemming from individuals with personal conviction of its importance. This has led to the creation of some formal legislation and the process of implementing IWRM. This consequently illustrates the potential important role of individuals in driving policy change.
The overexploitation and pollution of water resources of the San Jeronimo River, together with agricultural developments and deforestation, have generated conflicts between bordering communities. To address these, the San Jeronimo Basin Committee was created, mantling the role as a negotiating body and with a mission to implement IWRM. The key lesson learnt is that for success, it is crucial that local organisations take their social responsibility.
La Poza micro-basin is experiencing severe environmental degradation, mainly due to unsustainable deforestation practices executed to expand agricultural land. To combat the issues, action was taken to implement IWRM. Throughout the implementation, there has been a high level of community participation facilitated by extensive capacity building and training in environmental management. The primary lesson drawn from this example is the crucial importance of community participation for a successful implementation.
El Cerrito Canton community has spent decade attempting to get access to clean water. Action was taken to organise a Community Development Association, leading to the execution of a potable water project. The key insight drawn from this case is that, it is key for communities to have water access and management is their capacity to get organised.
The Reventazon River Basin has been subjected to severe degradation, mainly through water pollution, leading to proliferation of disease, increased cost of drinking water, and endangered biodiversity. Action was taken by establishing the Committee for the Management and Planning of the Reventazon River Basin working with conservation and land management. The key lesson for success is the importance of the coordination of the different actors that deal with the basin management.
In Costa Rica, action was taken to introduce water pricing to pay for services provided by forests in watershed areas. As a result, Costa Rica’s watershed owners are beginning to be rewarded for providing water, whether for drinking or for generating electricity. The main lesson is that initiatives that ensure local groups are included in the benefits of conservation are needed to involve them in helping to protect the water catchment areas.
