دراسة كرونولوجية للزحف العمراني على حساب الأراضي الزراعية بإستعمال صور الأقمار الاصطناعية

Abstract

Urban expansion reflects the continuous increase in population and the completion of huge projects and structures, which leads to an increase in demand for land, and to spare the decrease of these lands, especially agricultural ones, located in the northern part. Algeria directed its new expansion policy to the interior, where Bouira Province is one of these models that dealt with the new reconstruction policy within the redefinition of the general national framework, which ensures the development of a coherent, more coherent and sustainable area development. In parallel, these programs nominated the Bouira governorate to be the most affected by human activity, and thus the potential for its lands to be subjected to further erosion. In this context, this study aimed to follow the urban expansion through three periods by extracting maps to occupy the lands by analyzing the satellite and aerial photographs, and then quantifying the agricultural lands consumed by the urbanization in its various forms and directions using geographic information systems. In the end, let us conclude by highlighting the limits and advantages of remote sensing techniques in following up on the urban expansion in the Wilaya of Bouira.
