Assessing Urban Green Space Accessibility and Its Impact on Community Well-being

Thesis Abstract

Urban green spaces are vital components of sustainable cities, providing ecological, social, and health benefits that contribute significantly to community well-being. However, rapid urbanization has often resulted in unequal distribution and limited accessibility to these green areas, thereby exacerbating disparities in health and social outcomes among urban populations. This study seeks to systematically assess the accessibility of urban green spaces within the metropolitan area of Metroville and examine their impact on residents’ subjective well-being. The primary aim is to identify spatial inequalities in green space access and to evaluate how these disparities influence community health, social cohesion, and overall quality of life. The study adopts a mixed-methods research design combining quantitative spatial analysis with qualitative perceptions assessment. The targeted population includes residents aged 18 years and above across different districts of Metroville, with a stratified random sampling technique employed to select a sample of 400 respondents, ensuring proportional representation across socio-economic groups and geographic zones. Data collection involved Geographic Information System (GIS) mapping of green space locations, sizes, and proximities; structured questionnaires to quantify residents’ perceived accessibility, usage patterns, and well-being levels; and focus group discussions to gain deeper insights into community experiences and attitudes towards green spaces. Validity and reliability of the survey instruments were established through pilot testing and Cronbach’s alpha analysis, ensuring robust measurement of constructs related to accessibility and well-being. Data analysis encompassed spatial analysis using GIS tools to compute accessibility indices, followed by descriptive statistics to profile the sample. Inferential statistical techniques such as multiple regression analysis were employed to examine the relationship between green space accessibility and self-reported well-being measures, controlling for demographic variables. Thematic analysis was utilized to interpret qualitative data, elucidating community perceptions and the social value of green spaces. The study draws on the Social-Ecological Theory and the Theory of Planned Behavior to frame the interpretation of findings, emphasizing the interplay of environmental and individual factors influencing green space use and its benefits. Expected findings are anticipated to reveal significant variability in green space accessibility across different districts of Metroville, with peripheral or underserved neighborhoods exhibiting lower access levels. It is hypothesized that greater proximity and availability of green spaces are positively associated with higher levels of community well-being, including improved mental health, increased physical activity, and enhanced social cohesion. The study also expects to identify barriers to green space usage, such as safety concerns and lack of amenities, that mediate their impact on well-being. This research contributes novel insights into spatial equity and social determinants of health within urban contexts, filling gaps in empirical evidence regarding the link between green space accessibility and community well-being in developing city settings. It underscores the importance of equitable urban planning policies that prioritize access to green spaces as a strategy to promote healthier, more resilient communities. The main conclusion emphasizes that enhancing green space accessibility can significantly improve community health and social sustainability. Policy recommendations include implementing targeted urban greening initiatives in marginalized neighborhoods, developing inclusive design standards for green areas, and establishing community engagement programs to foster local ownership and sustainable use of green spaces. The study further advocates for integrating GIS-based accessibility assessments into urban planning frameworks and calls for longitudinal research to monitor the long-term impacts of green space interventions on community well-being.
