OUR PHILOSOPHY

Data hoarding destroys accountability.

When environmental data lives behind government portals and paywalls, only well-resourced institutions can act on it. Journalists can’t report. Researchers can’t study. Citizens can’t hold anyone accountable.

TerraFlow exists to fix that. We publish everything we collect — pollution reports, air quality readings, satellite-derived lake health indices, ward performance metrics — under an open licence. Free, forever.
