Production of plantain in the peri urban areas of Yaoundé : constraints assessment, impact on the area of supply and operating strategy. Plantain demand in Cameroon is increasing with population growth in urban areas. Because of extension of phytosanitary constrainsts in peri-urban agriculture, production zones that supply the nation's capital (Yaoundé) are shifting away from the town. A consequence of this situation is an increase of costs of transport and instability of the supply of plantain. This can be visualized through price analysis. However, the production belt around Yaoundé still an area that can be well exploited to maintain plantain production closer to the market, so as to ensure a regular supply of urban markets. To reinforce actor capacities to manage and control the main constraints identified, the agronomic research (i.e. CARBAP, IRAD) undertook the transfer and validation, within the framework of FRBC-péri urbain project, of a certain number of techniques and innovations to producers, extension workers and NGO representatives working in the peri urban zone. The techniques involved are: a horticultural technique of mass and fast multiplication of banana healthy plantlets, techniques of agronomic diagnosis, IPM techniques on banana practices. Expectations on the on going adoption of this package of techniques are (i) an important contribution to the renewal of a * Contact auteur : mengue_efanden@yahoo.com Agricultures et développement urbain 140 en Afrique de l'Ouest et du Centre close linkage between production and consumption zones, and (ii) a regular and secure food supply of the nation's capital (Yaoundé).
