Analysis of the Urban Form of Bechar through the Attributes of Space Syntax “for a More Sustainable City”

Located in the vast Algerian Sahara, Bechar has experienced over the years uncontrolled urban growth. It has evolved from a simple oasis and ksar (traditional settlement) to a city with a contrasting center and segregated outskirts. This growth has led to significant urban fragmentation that affected residents’ quality of life. This research uses space syntax theory to analyze Bechar’s urban configurations and their impact on functionality and sustainability. The study examines integration, connectivity, control, and intelligibility through axial maps and syntactic measures. Findings reveal that areas with high integration show better accessibility and reduced vehicle reliance, while segregated areas face accessibility challenges and limited services. Global integration values range from −1 to 1.192, averaging at 0.767, which indicates different accessibility among neighborhoods. These insights are crucial to identify areas where sustainable urban planning can mitigate adverse effects and enhance city efficiency. We created an axial map using DepthmapX v0.8.0 software and a modified digital QGIS map to collect data and measure Bechar’s urban properties. The methodology we used translates social behaviors into spatial representations, generating interpretative models for social and spatial phenomena. This article provides valuable information on the infrastructure and service needs, guiding strategic resource allocation. The proposed urban design strategies include urban canopies and optimized building ratios to reduce energy consumption and promote sustainability. To conclude, we recommend practical solutions to enhance the sustainability and functioning of urban areas similar to Bechar.
