More than 8,000 satellites orbit Earth, taking photos every day. Food security specialist and TED Fellow Catherine Nakalembe shows how she uses this imagery to help smallholder farmers across Africa prepare for floods, droughts and crop failures. Learn why real innovation isn’t always about shinier technology — it’s about making the tech truly fit the problem it’s solving. (Recorded at TED Fellows Films 2025 on April 7, 2025)

Interested in the application of this date and models to identify areas of earthwork potential for wetland creation for water storage.

With wonderful technology, rain and moisture can be produced and targeted to specific areas to keep drought, famine and pestilence. Thank the wonderful agriculture science and crop dusters who changed from dropping toxic pesticides to life enriching nutrients that feed soil and crops. Where would Africa look like with out Jane Goodal! This is crap! Unfortunately it is also what intelligent people call propaganda !

Amazing work! Using satellite data and AI to support farmers in Africa is a game-changer. Mapping crops, predicting disasters, and providing actionable insights can truly save lives and livelihoods. Technology applied with purpose can transform food security.
