The world has been asking: How will the United States turn its climate change talk into real action? President Obama began to answer that question this week when he announced his National Climate Action Plan, laying out concrete steps to curb climate change at home and abroad, including a policy that would bar the U.S. from financing conventional coal plants internationally.
The concrete steps he described are vital--most importantly because they represent actions, not just words. But everyone should also take note of the starting point in his speech. It reveals the critical role the international climate change process can play in stimulating climate action.
Working toward an equitable and ambitious international climate agreement in 2015 that is informed by science, considers the specific needs of the most vulnerable populations, and catalyzes sustainable development.
President Obama is in Africa this week to discuss development, investment, health, and, notably, food security. The trip comes on the heels of the president’s groundbreaking announcement of a U.S. Climate Action Plan. So it’s a fitting time for Obama and other global leaders to take notice of a strategy that addresses both climate change and food security in Africa—re-greening.
Re-greening—a process where African farmers manage and protect trees that grow on their farms, rather than cutting them down—is already beginning to transform the continent’s drylands. Supporting and scaling up the low-tech process can not only increase crop yields in drought-prone regions, it can mitigate climate change and reduce rural poverty.
The History of Re-greening in Africa’s Drylands
Re-greening in Africa first garnered international attention back in 2007, when the New York Times published a front page article entitled “In Niger, Trees and Crops Help Turn Back the Desert.” Lydia Polgreen, who was the NYT’s West Africa bureau chief in those days, had visited Niger and reported “at least 7.4 million newly tree-covered acres.” The NYT article revealed that this large-scale re-greening was not due to expensive tree-planting projects, but was the result of farmers protecting and managing young trees that regenerated on their cultivated land.
This re-greening did not happen everywhere. It was observed in particular in dryland regions with high population densities. Life in dryland areas presents many challenges, and farmers and decision makers are continuously searching for ways to restore their resilience and agricultural productivity.

If passed, the American Power Act (APA) would require companies to hold permits to emit GHGs for all emissions from facilities emitting more than 25,000 tons of carbon dioxide (CO2) or equivalent greenhouse gas. Most large U.S. chemical facilities would meet this threshold.
Climate change is a gradual change in the global temperature caused by the accumulation of greenhouse gases (GHGs) in the atmosphere.
