In Paarl, South Africa, organic winemaker Tyrrel Myburgh farms grapes in the Western Cape without modern, artificial irrigation. In drought-prone South Africa, where water can be scarce, using only rainwater to water drought-resistant grapevines is a radical step, as is allowing "a bit of a jungle" to grow among the vines, which are pruned and fertilized by free-roaming sheep.
CNN's David McKenzie visited the Joostenberg Winery, which has been producing wine for hundreds of years in the Western Cape, to see how it's going back to basics to meet the climate challenges of the future.
In Rwanda, gray crowned cranes were almost wiped out a decade ago. Captured as chicks and kept as status symbol pets in the gardens of hotels and private homes, by 2012, only around 300 remained in the wild.
But the species has undergone a remarkable recovery in the country thanks to local vet and conservationist Olivier Nsengimana. "I told myself someone has got to do something about it," he says. "Someone has got to make a change."
For Call to Earth Day, Rolex Awards Laureate Nsengimana tells us he wants to end the illegal trade in the rare bird.
