Many of the world’s most violent conflicts happen in the midst of some of its most valuable natural wildernesses. But protecting these areas’ biodiversity cannot happen until the fighting stops.

They are protecting nature while integrating the former fighters back into society, following the end of Colombia’s civil war in 2016.
