He leads the Alliance’s Global Campaign to EverGreen the Earth advocating for restoring degraded croplands, forestlands, and pasturelands, and removing at least 20 billion additional tons of CO2 annually from the atmosphere by 2050, through evergreening practices that also enhance biodiversity and improve livelihoods in the tropics.
