“…Market gardening is of greater interest to a certain category of people seeking for employment, food and financial sovereignty. In Benin for example, Nouatin et al (2010) showed that market gardening production was the main activity and sole source of income for market gardeners. Given the profitability of the activity, young school dropouts are increasingly interested in market gardening and this is in line with the results of Ahouangninou (2013).…”

Vegetables play a very important role in rural and urban communities as both food and a business opportunity. They are fast-growing species, with high nutritional values and able to generate income in a relatively short period compared to other crops. A characterization of market gardening systems was carried out with 368 producers from major market gardening sites in South-Kivu, in Easten of the RD Congo.The aim pursued was to assess existing systems and perspectives to enable steady transition to integrated, sustainable and resilient crop systems. The results showed that very few producers in the region practice plant integration. The typology carried out made it possible to identify three classes of market gardening farms based on adopted agronomic practices, production factors and possible outcomes derived from different systems. Most of the surveyed farms practice crop rotation and are market-oriented. However, they majorly differ in terms of farm size, practices of intercropping, permanent agriculture, mulching, production constraints and producer’s perception on the level of production. For instance, producers who are much more into intercropping also cultivate small areas (less than 0.25 ha). Results also showed that variables such as type of labour, cropping system, type of fertilizer used, mulching practice, adoption of permanent agriculture, producer’s perception of the level of soil fertility, and the water source used affect producer’s appreciation of the level of production obtained (p < 0.05). These variables can be mobilized for improvement of the market gardening system towards more sustainable, diversified and resilient systems.

“…The overall growth of the population of the city can be adjusted to an exponential function " Figure 3" with respect to its variation since it was at 14,000 and 60,000 inhabitants between 1961 and 1979 [25]. At the level of administrative division, the disparity of the spatial variation of average growth (Figure 2) is a component of the growth ratio [21].…”

Parakou occupies a strategic place in the socio-economic development of Benin due to its geographical position.Based on the Urban Land Registry data, and census data from the National Institute of Statistics and Applied Economics coupling with the statistical description and adjustment to the distribution Zipf rank-size model, allowed us to describe the urban hierarchy on the scale of Parakou localities over the period 1979 to 2013. The changes in densities of population occupation per decade show a tendency to sprawl from the 2000s and linear and quadratic adjustments are satisfactory (linear: 0.81≤ R² ≤ 0.95 and quadratic: 0.95 ≤ R 2 ≤ 0.98) and significant at 1% (P-value = 0.000) to 88%. The linear coefficients of Pareto are continuously decreasing (|α| = 1.749 to |α| = 0.831 between 1979 and 2002), and reflect that the weight of big cities keeps an influence on small and medium-sized cities over this period, while a slight increase was observed in the courtyard of the decade from 2002 to 2013 (|α| = 0.861 in 2013) and shows the effect of the creation of new districts with the gradual loss of the influence of the old districts of the central core. The results suggest that population growth of the city is occurred with urban sprawl controlled by exogenous factors of infrastructures or land type. Managements of spatial planning structures are then arrested in the guidelines to provide land for the human impacts control on natural resources of watersheds.

“…En Afrique subsaharienne, le maraîchage urbain est une activité qui joue un rôle important face aux problèmes liés à la croissance démographique galopante en milieu urbain (Nouatin et Bachabi, 2010 ;Kouakou et al, 2019). En effet, de la production à la vente, les activités maraîchères en milieu urbain permettent non seulement de résorber les problèmes de la sécurité alimentaire, mais aussi de réduire le taux de chômage et de contribuer au recyclage des déchets organiques utilisés pour la fertilisation des sols (Tella et al, 2013 ;Bouda et al, 2018).…”

Le maraîchage urbain joue un rôle très important dans la sécurité alimentaire et la résorption du chômage. Cependant, l’intensification des pratiques culturales peuvent altérer les propriétés physicochimiques des sols et réduire les rendements. La présente étude avait pour but de caractériser les pratiques culturales maraîchères à Brazzaville et de déterminer leur influence sur les propriétés physicochimiques des sols. Dans les sites retenus, des enquêtes structurées ont été menées auprès des maraîchers et des échantillons de sol ont été prélevés suivant des transects. Les analyses physiques et chimiques des sols ont été réalisées suivant les procédures courantes de laboratoire. Les résultats obtenus ont montré que les pratiques culturales dans les sites étudiés sont intensives. Les sols étudiés sont sableux à plus de 95%, acides, pauvres en matière organique et ont une CEC relativement faibles. Cependant on relève une sursaturation en bases échangeables sur l’ensemble des sites. Ainsi, cette sursaturation serait liée à l’intensification des pratiques culturales. Urban market gardening plays a very important role in food security and the reduction of unemployment. However, intensification of soil use can alter soil properties and reduce yields. This study aims to characterize vegetable farming practices in Brazzaville and to determine their influence on soil properties. In the selected sites, structured questionnaire was conducted among market gardeners and soil samples were taken following transects. Soil physical and chemical analyses were carried out following lab common procedures. The results showed that the cultivation practices in the sites studied are intensive. The soils studied are more than 95% sandy, acidic, low in organic matter and have a relatively low CEC. However, there is an oversaturation in exchangeable bases on all sites. Thus, this oversaturation would be linked to the intensification of cultural practices.
