TWAP River Basin Approach
• Need to assess all 270+ transboundary basins
• Develop a simple, scalable methodology
• Use existing information and modelling
• Use of composite indicators
• Short-listing criteria:
– Availability (i.e. cost efficiency in acquisition)
– Acceptability (i.e. ownership to information among
stakeholders)
– Applicability (i.e. relevance to transboundary issues)
– Aggregation at river basin level and comparability
between basins

• Raw indicator values ->
• Normalized values ->
• Relative risk categories
