The present study aims to analyze the consumption of household energy for cooking within households in Kinshasa, Matadi, Boma and Moanda, while placing particular emphasis on the factors that explain the determining factors in the transition to use butane gas. To achieve this, 1,300 households were surveyed in the four cities.The results of the study reveal that 80% of the households surveyed in the four cities use the energy mix for cooking. The charcoal for energy remains one of the preferred components of energy mix for cooking in reason of weakness observed in the supply of electric current. However, wood energy is one of the drivers of deforestation in developing countries. In addition, butane gas as one of the alternatives to wood energy is almost nonexistent in the energy pool in the sites visited (0.5%).Two factors (gender of the household head and joint use of electricity and charcoal) explain the mutation of households that have never used butane gas to butane gas (p <0.05). Indeed, households whose head of household is a man have two times the marginal propensity to migrate to the use of butane gas that households headed by women (p <0.05). By cons, households jointly wear electricity and charcoal were 0.4 times less rested first to migrate to the use of butane gas than households that use of other energy mix (p <0, 05).

This study is interested in the nature of the productions in the peri-urban agricultural concessions of the commune of Mont-Ngafula in Kinshasa. It is based on the concept of production system and questionnaire surveys. The results show that the agricultural concessions surveyed carry out several types of production of plant and animal. Fruit arboriculture is the most important type of crop in terms of area occupied and visibility. His development is linked to its capacity to quickly develop the land and to occupy it over the long term, necessary and sufficient conditions to obtain and keep the long-term occupation contract. This document is the only land title legally recognized by the Congolese state to users of agricultural concessions. Beyond the legal and environmental advantages linked to arboriculture fruit, the article proposes the use of an innovative fruit agroforestry approach, consisting in the participative domestication of fruits trees with high nutritional and commercial value mixed with food crops and animal production in order to contribute the increase of the food offer in the markets of Kinshasa and the professionalization of fruit arboriculture.
