In recent years, the concept of sustainable development has received renewed attention. As global resources shrink and needs continue to grow, the staying power of development impact is becoming central concern of both governments and donors. Recent studies have shown that only a small percentage of projects throughout the world have achieved sustainability, and the need for improving the long-term vitality of development investments is growing. No area in the world has shown more need of this than Africa. This paper outlines a conceptual approach for analyzing sustainability and synthesizes the lessons learned from the application of this model in recent field work. The model is based on the theory that two preconditions must exist before sustainability can occur: 1 ) commitment to long term sustainable development; and 2) beneficiary and stakeholder involvement via incentives which support achieving sustainability . Fieldwork-based recommendations to enhance sustainability include: 1) understand the long-term incentive structure that drives the project; 2) identify performance targets and communicate results early-on; 3) identify long-term recurrent costs and funding options; 4) build in flexibility to the project plan; 5) build-in ways for participants to support and “take ownership” of the project; 6) use local resources, both human and physical, and keep technologies simple; and 7) use marketing strategies to reinforce perceived, satisfactory benefits of the project. Case examples of successful African projects from West Africa, Burkina Faso and Kenya illustrate the application of the sustainability concepts. In the context of these illustrations, the sustainability framework appears useful for understanding and analyzing sustainability and provides a necessary addition to thinking about development projects and programs.
