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 priority problems identified in the TDA. It involves strategic thinking, planning, and establishing frameworks for monitoring and evaluation at both the regional and national levels. The overall process provides a framework for analyzing transboundary issues, engaging stakeholders, and strategically addressing priorities in an internationally coordinated manner.
