Where in the world is there potential for tropical-forest regeneration?

To restore tropical forests at scale requires cost-effective methods. An estimated 215 million hectares — an area larger than that of Mexico — have potential for natural forest regeneration, which could lead to an estimated above-ground sequestration of 23.4 gigatonnes of carbon over 30 years. A global map demarcates areas where forest has high and low potential to regenerate naturally.
