The purpose of conducting a Transboundary Diagnostic Analysis (TDA) is to scale the relative importance of sources and causes, both immediate and root, of transboundary waters problems, and to identify potential preventive and remedial actions. The TDA provides the technical basis for refinement of both the National Action Plans (NAPs) and the Strategic Action Programme (SAP) in the area of international waters of the GEF.
