Project Evaluation for Sustainable Rural Development: Plan Sierra in the Dominican Republic

A methodology of project appraisal combining the criteria of economic feasibility, acceptability, and sustainability is developed and applied to Plan Sierra, a watershed development project in the Dominican Republic. Feasibility is measured by the change in sustainable income due to the project; acceptability by the change in average annual income for the present generation; and sustainability by the difference between changes in sustainable and charges in average annual incomes. These three criteria may be achieved by schemes of tax and subsidy between project and non-project households and between present and future generations.
