Mathius Lukwago
Uganda Country Coordinator
Growing up as a boy scout, Mathius became passionate about nature. As simple as it sounds it gave him a purpose since his home was in the forest and he used it to discourage people from cutting trees. He grew up spending most of his time in the forest, walking, trekking, and discovering. People from his village used to collect firewood from the nearby forests. However, as time went on these trees started diminishing and the forest disappeared. As a Boy Scout, Mathius started focusing on planting trees to reforest the area. The limitation, however, was getting enough planting materials, so he started looking for tree planting workshops to get more information and contacts. In 2009, he was given an opportunity to support Trees for the Future’s Uganda program, formally including tree seed distributions and agroforestry trainings. Since then, Mathius says it is amazing to see what TREES has achieved, and how the communities have benefitted.
