Jamaica: Experiences of the water utility reform (#415)

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.

Transboundary: Basin Economic Allocation Model (BEAM); An Economic Model of Water Use Developed for the Aral Sea Basin (#432)

Steadily shrinking for decades due to unsustainable irrigation policies, the Aral Sea is under increasing pressure, making both allocation and availability major challenges. Action has been taken and the Basin Economic Allocation Model has been developed as a long-term decision support system to facilitate putting “value on water use”. This demonstrates that economic models can be applied to assess economic value maximization of different water uses.

USA: Application of watershed models for integrated water quality and coastal resources restoration in Chesapeak Bay ( #123)

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.
