FoE Sierra Leone is a grassroots environmental organisation founded in 1989, the same year they joined FoEI. The organisation has 25 local groups that promote environmental awareness, partly through their campaigns on sustainable societies. FoE Sierra Leone also seeks to advance women’s and girls’ roles in the sustainable management of resources. One example is the group’s Intermediate Technology Centre ECO-CENTER, where villagers are trained in tailoring, typing, blacksmithing and toy making. FoE Sierra Leone publishes a newsletter called COTTON TREE NEWS.

FoE SL also works with local farmers in order to promote the use of Compost/ arm yard manure in the production of organic food.
