AB  - Urban green areas play a vital role in enhancing the social balance, resilience, and environmental sustainability of urban settings. In Benin, while the landscaping sector is expanding, finding appropriate locations for creating green spaces remains a challenge. The purpose of this study was to identify areas conducive to the incorporation of green landscapes into urban planning within the Sèmè-Podji District. The approach used involved a multi-criteria analysis leveraging a combined GIS and Analytic Hierarchy Process (AHP) framework. Six key factors were considered: land use, elevation, slope, distance to major roads, proximity to urban hubs, and separation from flood-prone zones and water bodies. These were analyzed using the “Spatial Analysis” feature of ArcGIS to create a map highlighting areas suitable for the development of green spaces. The findings reveal that a substantial portion of land, approximately 44.77%, is highly favorable, and 20.88% suitable for landscaping in this district. The weighting of factors combined in this analysis reveals a 21% importance for land use and elevation, while distance from separation from flood-prone zones is given a weight of 18%. Distance to major roads and proximity to urban hubs are weighted at 15%, against 12% for the slope factor. This information provides guidance to decision-makers in selecting suitable sites for green spaces and their integration into the land management of Sèmè-Podji District. The results of this study also provide a scientific basis for addressing similar concerns in other cities.
