 City/countryside interface and dynamics of the peri-urban spaces of a South Mediterranean intermediate city. The case of Mostaganem (Algeria) 
The rapid changes that have taken place over the last three decades in Algeria at the economic, social, and political levels resulted in new urban and rural dynamics involving the emergence of a new spatial organisation which caused land use competition to increase in peri-urban areas. Structured by Mostaganem, an intermediate coastal town, and by a group of small agglomerations, the Mostaganem Plateau has a strong agricultural potential. It is currently experiencing, under demographic pressure, a process of peri-urbanisation which is transforming its rural space and generating changes that can be distinctive. This process creating interactions and confrontations between institutional stakeholders, rural and urban residents, landowners, and farmers. This article analyzes this process of reconfiguring the city/countryside relationships in the new urban context of Western Algeria and seeks to understand the actions and strategies of stakeholders through the example of Mostaganem.
