ABSTRACT
There is growing recognition of the transboundary nature of aquifer systems – systems that cross the borders of at least two countries – and a corresponding increase in international support for managing these complex systems. This paper considers these shared groundwater resources within the broader, global context of potable water supplies and intensifying water stresses. The paper notes the legal and development assistance frameworks for support to developing countries on transboundary aquifer issues, and examines a subset of transboundary aquifer projects implemented with Global Environmental Facility (GEF) support. Evaluative evidence from four recently concluded transboundary aquifer projects is used to highlight common issues and lessons for implementing future projects.
