Each year the world's forests in general and / or the hinterland of Kinshasa (DRC) in particular is reduced because it is managed as a mine, that is to say, we draw without restitution. The forest contains much more than wood, the main source of income for the peasants. How is the production of wood fuels practiced? What are the cumulative effects of income from non-rational production of wood fuels?
These two situations led us to assume that the causes are multiple and interrelated, generating various impacts. They are summarized in the reduction of biodiversity, the instability of the forest ecosystem, the depletion of a large part of the plant resources on which many economies are based. This article determines some cumulative effects on farmers' incomes.
