Each year entire communities commit to mass tree planting and maintenance sessions, lasting several days. Planting trees provides multiple benefits to local communities, as well as improving the ecosystem. Trees are used to stabilise the soil and are then sustainably coppiced to provide fuel wood, timber and craft materials (such as raffia) as sources of income. Reforestation and sustainable coppicing reduce pressure on the remaining fragments of indigenous forest in the region. Reforestation also provides a legitimate way for individuals and groups to claim land rights, if they can prove that they have worked to improve the land for a period of 5 years or more.
