Climate change will increase droughts in many parts of the world posing challenges for food production. Ethiopia is in the middle of the worst drought in 50 years. It’s also home to a successful experiment to make the land more resilient to drought. If we are going to adapt to our changing world, it’s experiments like these that will show us the way. With international help Ethiopian farmers have transformed dust bowls in green valleys by building dams, terraces, recharging ponds, and planting trees to slow down the water.
