How Satellites Are Supporting Farmers Across Africa | Catherine Nakalembe | TED

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)
