Hydrionis for finance and investment
Consistent, sourced, long-run water indicators across countries and companies, with the licence position on every figure stated up front — because a number you cannot license is a number you cannot put in a client report.
What you can answer here
Can we use these numbers in a commercial product?
Every dataset states its licence, whether redistribution is permitted and whether commercial reuse is permitted, resolved across every contributing publisher rather than asserted.
How has water availability moved over decades, not years?
Annual series from 1961 for national indicators, and decadal means computed over them with the input years recorded.
Where it stops: Reported water resource figures change with methodology as much as with hydrology. A step in a national series is often a change in how the country counted.
