Louise Mabulo grew up on seemingly strange farming tips from her parents and grandparents — like planting crops during a full moon or burying a rock beneath them. Now a farmer and climate activist herself, she sees how these practical nuggets of wisdom actually have scientific merit. Learn how she’s merging traditional knowledge with modern science to help farmers (and the world) adapt to a changing climate. 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.
