A study dealing with the impact of urban development on the availability of fodder in the harvestings areas of the district of Abidjan was carried out. The objective of this study was to assess the effect of urbanization on the supply areas of fodder plants in the District of Abidjan. Some statistics and surveys of fodder operators were carried out both on the harvest sites, the fodder sale outlets and on the livestock sale markets where the fodder harvested were sold. The surveys and observations carried out made it possible to identify the fodder sampling sites present in the study area such as Yopougon (Gesco, BAE, Bonikro, Km 17 and the high school crossroads), Abobo (Adjin, Quartier cimetière, Abobo-Baoulé, Paris village), the Adjamé - Abobo (Paillet, Williamsville cemetery) and Port-Bouet 1 axis. A total of 45 loads containing bundles of fodder have been identified and in which 23 species divided into 8 families have been identified. The poaceae family is the most dominant with 35% of species encountered. Each bale of fodder is usually made up of a mixture of several plant species. The results of the survey indicate to us that, the sampling areas are increasingly very distant due to urbanization, which leads the forage farmers to travel long distances to obtain their supplies. According to the latter, despite the long distances to travel for the harvest, this has no influence on the floristic list of species and on the quantity and cost of their product. However, the actors are aware of the degradation and disappearance of the forage harvesting areas in favor of urbanization.
