Refugees living at Minawao camp in northern Cameroon have turned the area green, providing shade, improving the soil, and attracting water. As part of a UNHCR project to reduce carbon emissions, they have planted 360,000 seedlings in the past four years on an area as large as 250 football fields. Thanks to the shade cover provided by the trees, food can now be grown in the camp. Refugees use eco-friendly briquettes, made from household waste, for cooking, which creates jobs as well as saving trees.
