South Africans could face increased pressure on food prices and a higher risk of drought over the next two years after the United Nations' World Food Programme warned that a powerful El Niño weather pattern could push a staggering 49 million people into acute food insecurity globally by the end of 2027.

How do you heal a broken watershed? You build living speed bumps!

When hillsides lose their vegetation, rainwater races downhill, violently carving deep, dry canyons called gullies. For years, we tried stopping this with giant concrete walls at the bottom of the hills, but they just filled with mud. Ecological engineers have a better way: Vegetated Check Dams!

Instead of one giant wall, we build hundreds of tiny, living fences all the way up the mountain. Here is how they heal the earth:
1️ The Living Speed Bump: We weave fallen branches and plant live willow stakes directly across the eroded gullies. When floodwaters hit them, the water slows to a crawl.
2️ Catching the Dirt: Because the water slows down, it drops all the valuable topsoil it was washing away, physically refilling the deep canyons with rich earth!
3️ Growing Stronger: Those willow stakes sprout and grow roots deep into the trapped soil. The older the dam gets, the stronger it becomes, permanently turning dry, dangerous gullies into lush, green, slow-moving wetlands.

We are stopping floods and saving soil by slowing the water down!
