Dengue risk map

Happy Earth Day, 22 April 2026 – a global call to act and protect our planet. At the European Space Agency, that action begins in orbit, where satellites deliver a continuous, global view of Earth and track environmental change. Working with partners, ESA turns this stream of data into actionable information, helping governments and communities respond faster and more effectively to climate-driven risks.

As climate change accelerates the spread of mosquito-borne diseases, satellite-based early warning systems are giving health authorities a critical head start. By fusing Earth observation data with machine learning, ESA and UNICEF have developed a digital platform that helps countries predict, prepare for and respond to dengue and malaria outbreaks weeks before they escalate.
