Cities, facing accelerated spatial dynamics, generate adverse effectson nature as is the case of Abidjan. This African metropolis iswell-known for its rapid urbanization- with more than three millionpeople living there. Yet, since it has been designated as the Ivoriancapital city, its development has been planned. So as not to jeopardizebiodiversity as regards economic growth, the government adopted apolicy to serve the urban ecosystem by creating a national park withinAbidjan and a reserved forest (Anguededou ) on the northern outskirtsof the city. But beyond the economic benefits, there stand problems dueto the management of population growth. At the economic level, informalactivities develop in a chaotic way. Governments try in vain toreorganize them and environmental impacts are significant. Thedevelopment of economic activities along roadways makes it difficult toreach green city objectives. There is also a significant reduction ofnatural areas for the benefit of housing. Abidjan spreads to meet thehigh demand for housing of urban people when suburban agriculture iscontinually threatened. The degradation of Abidjan natural heritage isso worrying that the impacts of population pressure extend to protectedareas. For agricultural practice, some populations infiltrated theclassified forest of Anguededou a few years ago and even settled there.The threat of the primary forest’s extinction of Abidjanoutskirts is real while the measures against the deterioration of theurban environment do not seem to consider the problem of city spread.
