A scientific foundation
Aqueduct 4.0 provides 13 indicators covering water quantity, quality and reputational risks.
Water Intelligence · WRI Aqueduct
Water is global. Understanding it starts locally.
Make complex water-risk information easier to understand—and use it to ask better questions about the places we live, work and visit.
Location adds meaning
BlueGo puts water awareness into a geographical context, with practical guidance for users.
Context before conclusions
Long-term risk indicators inform priorities. Local observations and official restrictions complete the picture.

From scientific data to practical awareness
A clearer picture. Better questions.
Baseline water stress compares withdrawals with available renewable surface and groundwater. Aqueduct is a prioritisation tool: regional expertise and local data are essential to evaluate an individual site.
