ریخت‌شناسی انسجام: تحلیل پیکره‌بندی فضایی شبکه‌های اجتماعی و هم‌بستگی آن‌ها با فرم شهری در محله‌های گسسته کابل

This study investigates the mechanisms underpinning social cohesion in post-conflict, multi-ethnic urban contexts, emphasizing the dialectical interaction between spatial configuration and social network morphology in shaping social cohesion at the neighborhood scale. The central research problem focuses on understanding how the physical form of the urban environment interacts dynamically with social network structures to produce varying levels of social cohesion within neighborhoods that share similar ethnic compositions. Kabul, Afghanistan, represents a paradigmatic case of such a complex post-conflict, multi-ethnic urban setting, and was selected as the focal site for this investigation due to its intricate spatial patterns, heterogeneous population, and historical experience of urban disruption and reconstruction.

Existing literature on urban social cohesion and post-conflict city dynamics exhibits three critical gaps. First, a theoretical gap persists in the absence of a unified conceptual framework that can integrate the spatial and social dimensions of cohesion while accounting for their dialectical co-evolution. Second, a methodological gap exists in the lack of systematic approaches that can simultaneously leverage the quantitative and relational analytical power of Space Syntax and Social Network Analysis (SNA). Third, a contextual gap is evident due to the scarcity of empirical studies in sensitive, non-Western, post-conflict, and multi-ethnic urban contexts, which limits the generalizability of findings predominantly derived from Western cities. Addressing these gaps is essential for developing contextually sensitive theories and practical interventions aimed at enhancing urban cohesion in post-conflict environments.

To address these research challenges, the study employs a triangulated, three-layered methodological framework. First, Space Syntax analysis is applied to quantify spatial configuration, measuring key indices such as integration and connectivity that capture the permeability and accessibility of urban form. Second, Social Network Analysis (SNA) is used to map and quantify social network morphology within neighborhoods, analyzing measures including network density, diameter, and inter-ethnic ties to capture the structure and resilience of social relationships. Third, Structural Equation Modeling (SEM) is employed to rigorously test causal relationships between spatial and network variables and to identify the mediating effects of network morphology on the relationship between spatial configuration and social cohesion. This methodological integration allows for a comprehensive understanding of how physical and social structures co-evolve to produce differential cohesion outcomes.

Empirical data were collected from three strategically selected neighborhoods in Kabul—Rikakhana, Karte-Sakhi, and Dahmazang. Data sources included spatial surveys and mapping, structured questionnaires administered to 450 households, and 50 in-depth semi-structured interviews. This combination of quantitative and qualitative data ensures a robust and multi-dimensional understanding of both observable patterns and the underlying mechanisms driving social cohesion.

Quantitative results reveal that spatial configuration exerts a direct positive effect on social cohesion (β = 0.35), yet the most substantial influence operates through social network morphology as a mediating variable (β = 0.48 for the direct effect of networks, β = 0.17 for the indirect spatial effect mediated via networks). For instance, Rikakhana, characterized by high spatial integration (1.25) and dense social networks (0.67), exhibits the highest observed cohesion (0.72), whereas Karte-Sakhi, with low spatial integration (0.67) and sparse network density (0.34), records the lowest cohesion (0.48). These findings demonstrate that while spatial accessibility facilitates interactions, the organization and structure of social networks significantly amplify the effects of spatial design on cohesion outcomes.

Qualitative findings provide rich contextual understanding of the mechanisms underlying these quantitative patterns. In Rikakhana, public spaces such as marketplaces and open courtyards with high accessibility serve as hubs for inter-ethnic interactions, fostering trust and reciprocity among residents. Conversely, Karte-Sakhi’s predominantly cul-de-sac spatial patterns, combined with a scarcity of collective public spaces, reinforce social isolation and ethnic boundary-making, limiting the formation of bridging social ties. These insights underscore the importance of considering both the physical and relational dimensions of urban life in the design and evaluation of interventions aimed at promoting social cohesion.

The study’s theoretical contribution lies in the development of an integrated social-spatial morphology framework that conceptualizes spatial form and network structure as two mutually constitutive dimensions of urban cohesion. Methodologically, the study introduces an innovative protocol combining Space Syntax, SNA, and SEM to empirically examine the co-evolution of urban form and social networks. Contextually, the research produces novel empirical evidence from sensitive, multi-ethnic, post-conflict neighborhoods, enabling the development of theory that is both empirically grounded and sensitive to local urban realities.

In conclusion, the study demonstrates that social cohesion emerges from the dynamic co-evolution of spatial configuration and social network morphology. Permeable and continuous urban spaces facilitate everyday encounters, reorganizing networks toward higher density, reduced diameter, and stronger inter-ethnic connections, which in turn reinforce cohesion directly and sustainably. The findings further indicate that, under integrated spatial-network configurations, ethnic diversity can strengthen rather than undermine social cohesion. Accordingly, urban planning in post-conflict, multi-ethnic contexts should prioritize interventions that simultaneously enhance spatial permeability (the “hard” dimension) and foster inter-ethnic social ties (the “soft” dimension), ensuring that both physical and social infrastructures contribute synergistically to cohesive, resilient urban communities.

Overall, this research provides a robust, empirically grounded framework for understanding and enhancing social cohesion in post-conflict cities, demonstrating the crucial interplay between urban form and social networks and offering actionable insights for urban planners, policymakers, and scholars engaged in rebuilding socially resilient urban environments.
