This article analyzes the contribution of market gardening to household income in the N'djili valley in Kinshasa. The Probit and Tobit models were estimated to take into account respectively: (1) the decision to participate in market gardening activities, (2) and the decision to depend on these activities. The results of the estimates showed that the decision to participate in market gardening activities is significantly affected by the variable age, level of study and the place of sale of market gardening products. Household dependence on market gardening is positively affected by gender, age and level of education and simultaneously negatively influenced by household size, experience in market gardening and sales locations. In addition, statistical analyzes indicated that a typical household earns on average an income of 222,000 Congolese francs for a combined crop cycle of at least two crops.
