Abstract
The population's growth in both territories of Abomey and Bohicon has generated a dynamic of spatial occupation transforming these different spaces. This article has analyzed urban dynamics and the changes that take place there. The adopted methodology combines the documentary research and the diachronic method. The data from the various censuses of the population, the observation and the Landsat TM, ETM +, OLI / Shots images were processed and analyzed. From 1986 to 2017, tree and shrub savannahs and swamp formations lost respectively 89% and 35% of their areas in Abomey, while in Bohicon these savannas lost 94% to the detriment of built-up areas, mosaics cultures, fallow lands and marsh forest. The artificialized surfaces of the territories are 50% and 62% of which 17% and 19% of built-up areas respectively in Abomey and Bohicon In addition to its cultural and administrative functions, Abomey acquires the university function while Bohicon financial, tourism which adds to commercial, administrative and industrial function. The growth of these territories is done by adding new surfaces to the central urban core, so as to merge two districts forming a conurbation.

Abstract: (french)
L’accroissement de la population dans les territoires d’Abomey et de Bohicon a engendré une dynamique de l’occupation spatiale transformant ces différents espaces. Le présent article a analysé la dynamique urbaine et les mutations qui s’y déroulent. La méthodologie adoptée combine la recherche documentaire et l’approche diachronique. Les données des différents recensements de la population, l’observation puis les images Landsat TM, ETM+, OLI/Tirs ont été traitées et analysées avec les outils statistiques et le logiciel ArcGIS 10.4. De 1986 à 2017, les savanes arborées et arbustives et les formations marécageuses ont perdu respectivement 89% et 35% de leurs superficies à Abomey tandis qu’à Bohicon ces savanes en ont perdu 94% au détriment des zones bâties, de mosaïques de cultures et jachères, et de forêt marécageuse. Les surfaces artificialisées des territoires sont de 50% et 62% dont 17% et 19% de zones bâties respectivement à Abomey et à Bohicon En plus de ses fonctions culturelles et administratives, Abomey acquière la fonction universitaire tandis que Bohicon celles financières, touristiques qui s’ajoutent aux commerciales, administratives et industrielles. La croissance de ces territoires se fait par adjonction de nouvelles surfaces au noyau urbain central, de sorte à fusionner deux arrondissements formant une conurbation. Les taux d’urbanisation réels ont oscillé avant de s’établir entre 2013 et 2017, à 84% pour Abomey et 58% pour Bohicon. Ces transformations seraient nourries par la périurbanisation qui certainement pourrait engendrer l’étalement urbain dont les facteurs sont à identifier en vue d’une gestion durable de ces territoires.
Author Keywords: étalement urbain, doublet, fonction, fusion, centre-ville.
