Sentinel Index™

All issues · New issues publish on Mondays.

Why we built it

Most of what the world eats begins on small farms that no one measures week to week. The Sentinel Index pairs public satellite data with published reporting to show what is changing on that land, and for the people who work it, before the harvest reaches market. Each issue tells one story from the first mile of the supply chain, with every number linked to a public source, so readers can check it and draw their own conclusions.
