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.
There were concerns that Lake Arenal in Northern Costa Rica was threatened due to problems of deforestation and possible premature sedimentation, leading the government to take action, resulting in successful national and local benefits in terms of energy produced and area irrigated. The most important lesson learned is the importance of consulting all parties involved before initiating the project to achieve the best result.
Despite high water availability in Jamaica, uneven distribution in both time and space creates local scarcity. Hence, it is problematic to distribute water adequately to all sectors, and to develop abstraction points for water treatment. To address the issues, action was taken and a Water Sector Reform was proposed, including a Water Sector Strategy and Action Plan. From this experience, the lesson learned is the importance of coordinating activities and harmonising policies, legislation and institutions.
Although the West African Sub-region is well advanced in IWRM, some countries still need more support. A strategy was developed to help countries that had formally requested IWRM planning assistance. The lesson learnt is that participatory processes take much longer than non-participatory ones, nonetheless, they are still favourable since they provide a platform for discussion and a place to exchange ideas.
The Senegal River has seen considerable migration of people in view of worsening drought and desertification. Furthermore, it is subjected to threats such as loss of arable land, and pollution from waste. To address the problems and to realise the potential of the basin, the Senegal River Development Organisation was established by three of the riparian states. This case gives important insights into how an institutional and legal infrastructure can be built in stages.
The Niger River basin is of importance to the region. The Niger Basin Authority was established to foster, promote and co-ordinate studies and programs relating to the Niger River basin. Today the authority is required to promote co-operation among the member countries and to ensure integrated development of its resources. This case illustrates and provides key insights into transboundary river basin management.
Due to increased agricultural irrigation and large scale dam projects, and inappropriate land and water management practices, the water inflow to the Komadugu Yobe Basin has dramatically been reduced. Action has been taken to establish a legal and policy enabling environment, as well as to increase knowledge among the local communities to establish more sustainable behaviour. The main lesson learnt was that although a multi-stakeholder participatory approach is slow, it helped to mobilise partnership.
Despite an almost abundance of water, most water users in the South-western region of Burkina Faso regularly face water shortages due to an intensification of irrigated agriculture. Action was consequently taken to set up the Local Water Committee. The lesson learnt is that in the realm of the water sector, it is crucial for the state, local authorities, civil society and the private sector to collaborate to find new potential solutions.
