🚨 New paper! 🌍🛰️🌧️

More Earth observation data doesn’t automatically mean better humanitarian decisions.

A new framework examines how satellite data influences decision-making—for better, worse or not at all—drawing on experiences managing flash flood risk in Ecuador. Read: https://ow.ly/crah50ZLJO2

🚨 New paper out! 🚨 🌍 🛰️ 🌧️
EO (satellite) data can improve early warning systems, anticipatory action and subsequent disaster risk management and humanitarian action, however doing so also invites new risks that must be described and managed
