An area about the size of a city block in Manhattan is typically cut down per person per year in Cameroon for use as firewood or to make charcoal. The Minawao refugee camp in Cameroon, which has a population of more than 60,000 people who fled from Boko Haram, has only led to a further decimation of the trees that once filled the area. Now refugees at the camp are replanting the trees with the help of a startup that’s providing the refugees with an innovative, biodegradable paper cocoon designed to help young seedlings grow. The refugees are also turning agricultural waste into “eco briquettes” that can be used for fires instead of wood.
