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.
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.
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.
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.
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.
Following the reorganisation of the water sector in Zambia, an action that decentralised service provision, it became crucial to monitor the service providers and the consumer experience. Action was taken to set up Water Watch Groups that have as their responsibility to raise public awareness about rights and obligations. This case study, concludes that consumer involvement is the key to the success of water sector reforms.
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.
With the introduction of IWRM, South Africa has shifted the design and implementation of water management to local institutions. This has created a demand for innovative methods for local stakeholders’ participation. Action was taken to introduce the participatory process Companion Modelling that is based on the use of simulation models and role playing games. Consequently, this case study illustrates new methods and tools that facilitate dialogue and improve decision-making skills of local stakeholders.
In Uganda, the National Water and Sewerage Corporation (NWSC) provide most drinking water, however, this is predominantly in urban areas. Attempting to improve water provision in rural areas, a programme supported by the World Bank was initiated. The main action taken was to commercialising service delivery through public-private partnerships. Despite being viewed as a great success, this case study highlights that circumstances can change and thus be different from those anticipated during the bidding stage.
The Maasai live in an area of Kenya that has no water in the rivers for half a year. To address the water scarcity, the Water for the Maasai project was initiated. In this project, the Maasai, the donor and the NGO work closely to cooperate in the key issues of education, training and long-term guidance. The key lesson is that it takes time to build trust among donors, NGOs and native populations.
