CHEMA is an environmental organization that deals with afforestation, water projects, agroforestry, beekeeping, organic agriculture, community forest management and environmental education. Founded in 1991 with programs in afforestation and tree nurseries, CHEMA has become the largest environmental non-profit organization in the Kagera Region. Our success builds from our focus at the grassroot's level.

CHEMA is part of the Catholic Diocese of Rulenge and receives financial support from MISEREOR.
