The document discusses the TDA/SAP process for addressing environmental problems in transboundary water systems. The TDA involves a technical analysis to identify and prioritize transboundary problems. The SAP then establishes strategic priorities, plans, and mechanisms for implementing actions to resolve the key issues identified in the TDA. It involves strategic thinking, planning, and developing institutional arrangements for monitoring and evaluation. The overall process provides an analytical basis and strategic framework for collaboratively tackling environmental challenges that cross national boundaries in shared water systems.
