The Costa Rican government decided to revise its system of water use levy when it became evident that it was disproportionately low. Action was taken by key stakeholders to reconstruct a design of the water use levy to reflect two basic elements of water charge: water use rights and environmental water services. From this experience, the most important lesson is that political will must support legal and technical works when reforming economic instruments.
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.
The water resources of The Bahamas are threatened by over-abstraction, misuse and pollution. In the past, water management in the Bahamas has been conducted through a single-sector approach. To address its issues, actions have been taken to move towards IWRM and a multi-sector approach. In particular, attention has been focused on improving stakeholder participation and advancing political commitment. Presently only being partially successful, IWRM implementation in Bahamas highlights that it is a long term process.
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.
Tourism has placed great pressure on the natural environment of Jamaica. Action was taken through a USAID funded project that aimed to increase water use efficiency and improve environmental management. The key lessons are the value of demonstrating the benefits locally as well as to institutionalise the programme.
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.
Kafue Flats are the vast open floodplain of the Kafue River, important for fishing, cattle grazing, sugar cane farming, and production of hydroelectric power. Increased human pressure is, however, threatening the ecosystem. Action was taken by WWF to create partnerships between different stakeholders. Furthermore, an IWRM plan has been initiated. This case illustrates how integrated planning can bring together stakeholders with diverse interests.
The Great Ruaha River is important in terms of the utilisation of its water for agriculture, meeting the ecological needs, and the generation of hydroelectric power. During the early nineties, a series of zero flows in this previously perennial river alerted the authorities to hydrological and environmental change. A project was initiated to investigate the reasons and possible solutions. This case illustrates the critical role and benefits of long-term, large-scale, interdisciplinary research in approaching complex problems.
Unclear ownership and no formal mechanism to manage the water source of the Mvutjini earth dam have caused unfavourable conditions for the local community. Action was taken to implement IWRM by the Swaziland Country Water Partnership, aiming to revitalise the dam and set up management rules by involving local stakeholders. This case study illustrates that collaboration and partnership between institutions involved in water resources management is vital for success.
Poor domestic and international coordination between South Africa, Swaziland and Mozambique has led to conflicts over the water utilisation of the Komati River basin. Despite these challenges, action has been taken to strengthen the institutional and legislative framework. These actions demonstrate that in the contexts involving transboundary water resources, a strong institutional framework can promote political and economic cooperation between riparian states.
