Urban green infrastructure and social cohesion in Lagos Metropolis, Nigeria

Abstract

Urbanisation has increasingly resulted in social fragmentation, insecurity, and health challenges in cities worldwide. Urban green infrastructure (UGI) presents a viable solution, by promoting social interaction and enhancing safety and well-being. While an increasing body of scholarly literature has examined the interaction between UGI and its social impacts in the built environment, empirical studies specifically addressing the connection between UGI quality and social cohesion in densely populated urban areas of developing countries remain limited. This article investigates the relationship between UGI and social cohesion in Lagos Metropolis, Nigeria. It aims to explore how the presence, accessibility, and quality of green spaces affect social interactions, community trust, and residents’ sense of belonging. Using a multi-stage sampling approach, the study surveyed 1,560 residents through questionnaires administered in their neighbourhoods. Findings from descriptive statistical analyses and categorical regression reveal that, despite residents perceiving the current green infrastructure as substandard, there is a strong belief that it positively influences social cohesion. The study identifies three critical dimensions of UGI, which include the deterioration of green spaces, accessibility for recreation, and proximity to residences, as factors that significantly impact on social cohesion. These insights can inform urban planning policies aimed at creating inclusive and sustainable green spaces, ultimately improving social cohesion and enhancing the overall well-being of urban communities in Lagos and similar contexts throughout the Global South. By prioritising these dimensions in urban planning, cities can support stronger community ties and improve residents’ quality of life.
