Throughout the world, the forest remains the most stressed ecosystem for various human needs. The humid tropical forests found in the Third World are in constant decline due to clearing for cultivation, bush fires and the overexploitation of firewood and charcoal. «In the year 2000, the forest area covered about 3.9 billion hectares, or roughly 30% of the Earth’s land surface, but every year the global forest cover is shrinking» (Lester, 2001). As far as DR Congo is concerned, «wood energy covers 82% of total energy needs and 99% of housing sector needs» (Zins and Kambale, 1989; Gerkens, 1989). Furthermore, «the urban consumption (Kinshasa) of wood as a source of energy led to the disappearance of nearly 16,000 hectares of forest in 1980 and 80,000 hectares in 1985 for the other cities of the country» (Vangu, 1988). «The southern Shaba region alone is losing more than 40,000 hectares of forest per year. The needs of the city of Lubumbashi in energy-wood lead to deforestation of more than 10,000 hectares per year» (Binzangi, 1989). «Households in the city of Kisangani use wood energy for cooking, i.e. 226,908 bags of charcoal per year, i.e. 14,300 tonnes of charcoal per year compared to 1,802,124 bundles of wood, i.e. 60 384 tons per year. Consequently, the total quantity of wood-energy in Kinshasa is estimated at around 4.8 million m3 of wood per year (Projet Makala/CIFOR, 2011)». In the hinterland of Kinshasa, the regressive series at the level of forest formations continues its trajectory in an interrupted manner since the rate of deforestation has already reached 55.81%. Furthermore, the average monthly production of 41 kg wood bundles is 13,800 ± 84.85 while that of 51 kg charcoal is 45,750 ± 49.50« (Mavinga, 2019). These few estimates indicate the extent to which wood energy occupies a prominent place in the lives of the world’s populations in general and Congolese in particular.
