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 or a client report?
Every dataset states its licence, whether redistribution is permitted and whether commercial reuse is permitted, resolved across every contributing publisher rather than asserted. Which attribution passes to you, and which credit Hydrionis merely requests, are kept separate — because a deliverable can fail on the first and never needed the second.
Where it stops: A derived value is never more freely usable than the most restrictive source behind it, and no arrangement with Hydrionis widens what a publisher withheld. Where a figure may be displayed but not redistributed, it cannot go into a client deliverable as data however it was computed.
Which of the places we are exposed to have a deteriorating hydrological record?
For a geography Hydrionis holds a long record for, the record itself: rainfall, flow or groundwater against its own history, with the periods it does not cover marked rather than smoothed over.
Where it stops: Hydrionis cannot currently take a portfolio. There is no way to give it a list of sites and receive a screened result, because that needs an account and Hydrionis has none. A named list of places can be answered as a bespoke enquiry today; a self-service screen cannot.
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.
