The Miraculous Device That Saved My Farm — and Changed My Life | Josephine Waweru | TED

Exhausted from carrying water up a hill to keep her small farm in Kenya thriving, Josephine Waweru received an unexpected call that offered a nearly unbelievable solution. She shares how one simple device allowed her crops (and her dreams) to flourish — and offers a glimmer of hope in the face of growing climate uncertainty. (Recorded at TED Countdown Summit 2025 on June 16, 2025) Countdown is TED’s global initiative to accelerate solutions to the climate crisis. The goal: to build a better future by cutting greenhouse gas emissions in half by 2030, in the race to a zero-carbon world.
