Description:
L’exploitation artisanale de la forêt miombo et sa régression s’intensifient suite à l’accroissement des besoins énergétiques des centres urbains du Katanga. Nous avons tenté de comprendre les ressorts des filières bois-énergie et avons fait le choix de cibler l’approvisionnement de la ville de Lubumbashi. Les résultats montrent que, bien que l’énergie électrique soit aussi utilisée, la quasi-totalité des ménages font de plus en plus usage de l’énergie des combustibles végétaux, 72 % des familles n’utilisant que l’énergie du bois pour leurs ménages. La quantité totale de charbon de bois entrant mensuellement à Lubumbashi par route en 2008 (mois de juin-juillet) et selon différents modes de transport est de l’ordre de 805,4 tonnes, soit une consommation minimale d’environ 1 sac de 50 kg de charbon de bois par ménage et par an. Ces combustibles, en provenance essentiellement de l’arrière-pays immédiat, empruntent surtout les axes Likasi et Kasenga dans le secteur nord de la ville, contribuant à 53,5 % du total des entrées. Ces résultats permettent de comprendre que, avec les activités minières, la production du charbon de bois est une des causes principales de la fragmentation et dégradation des forêts au Katanga. On espère que l’énergie électrique puisse prendre le relais de l’énergie fournie par les combustibles afin de protéger les forêts dans la région de Lubumbashi. Artisanal exploitation of the miombo forest to cover the increased energy needs of the urban centres of the Katanga Province accelerates its regression. We tried to understand the origin of the wood-based energy consumption and have chosen to target the supply of the city of Lubumbashi. Although fuel based on wood and electric power are the two types of energy used, our results indicate that virtually all households make more use of fuel based on wood; 72% of the families only use this type of energy for their household needs. The total quantity of charcoal entering monthly in Lubumbashi in 2008 (months of June and July) by road and by different modes of transport is estimated at 805.4 tons, which corresponds to a minimum consumption of 1 bag of 50 kg of charcoal per household per year. These wood-based fuels are extracted mainly from the immediate hinterland of Lubumbashi, especially from Likasi and Kasenga situated in the north of the city, contributing to 53.5% of all entries. Our observations suggest that, together with the mining industry, the production of charcoal is a major cause of forest fragmentation and degradation in Katanga. In order to protect the forest ecosystems in the region of Lubumbashi, hope relies on electrical energy.
