WHAT IT SOLVES
From water uncertainty to a clear course of action
Without strategic assessment
– Unclear water and regulatory conditions on shared basins
– Decisions made without quantifying the real risk
– Short-term, reactive planning in the face of scarcity
– Exposure to increasing social, political, and economic costs
With Transboundariness
+ Customized hydrogeological, climatic, and regulatory assessments
+ Risk quantification to support every decision
+ Strategic roadmap for the short, medium, and long term
+ Support during implementation, not just the initial assessment
