Fruit Trees Contribution to Food Security in Tropical Urban Environment: Instance of Commune of Limete in Kinshasa- Democratic Republic of Congo. Problems of hunger and malnutrition in urban environnements force the populations to exploit all the food resources available. This work investigates the contribution to the diet of the population of the edible fruits produced by the 19 species of trees found in a district of Kinshasa. An investigation carried out in 1.09% of the 18,475 household plots of the commune of Limete permitted to estimate at approximately 47,000 feet the number of trees planted there and their annual production at approximately 4.087 tons. The six main species (Mangifera indica, Persea americana, Elaeis guineensis, Carica papaya, Dacryodes edulis and Musa paradisiaca) account on their own for an approximate total of 36,400 feet. The contribution of these species to the population alimentation was estimated respectively at 10.9 g, 6.1 g, 4.5 g, 4.4 g, 1.8 g and 0.6 g of fruits per person and per day. The control of certain environmental- friendly techniques and environmental education relating to the trees in urban environment should increase the importance of this contribution.

Inventory of Vegetal Species Cultivated in Plots Gardens in Urban Environment. Instance of Limete Commune-Kinshasa- Democratic Republic of Congo. A survey carried out in 201 plots of the "commune" of Limete permitted to inventoriate nineteen species of cultivated vegetables and 764 plants of 18 fruit-tree species planted or kept in this area. Mangifera indica is the most planted tree species and Ipomoae batatas is the most frequently cultivated vegetable species. Promoted and supported, this urban agriculture can modify the town ecosystem characteristics with a vegetation able to purify the air, to regulate the climate, to restore soil fertility and to provide vegetables and fruits to the population.
