Comparative Analysis of Urban Green Space Accessibility in European and North American Cities

Thesis Abstract

Urban green spaces are vital components of sustainable city landscapes, providing ecological, social, and health benefits; however, disparities in their accessibility remain a significant concern in urban planning and policy formulation. This study addresses the persistent inequality in urban green space access between European and North American cities, seeking to identify underlying socio-spatial factors influencing distribution patterns and to compare urban green space accessibility across these regions. The primary aim is to conduct a comprehensive comparative analysis that elucidates the determinants and extent of differences in access, thereby informing equitable urban greening initiatives. The specific objectives include (1) assessing the spatial distribution of green spaces in selected European and North American cities; (2) evaluating socio-economic and demographic factors influencing access; (3) applying GIS-based spatial analysis to quantify accessibility disparities; and (4) examining policy frameworks that govern urban green space allocation. The study employs a mixed-methods research design, integrating quantitative spatial analysis with qualitative policy review. The population encompasses residents, urban planners, and environmental policy officials in ten major cities—five from Europe (e.g., Copenhagen, Berlin, and Amsterdam) and five from North America (e.g., Toronto, Chicago, and Vancouver). A stratified random sampling technique will select 1,000 survey respondents across these cities, ensuring representation across socio-economic strata. Data collection instruments comprise GIS spatial datasets, structured questionnaires, and semi-structured interview guides. GIS layers include land use maps, green space locations, and accessibility indices, while survey questionnaires capture socio-economic variables and perceptions of green space accessibility. Validity and reliability of instruments will be ensured through pilot testing and expert validation, and triangulation will enhance data robustness. Quantitative data will be analyzed using Geographic Information System (GIS) spatial analysis, including network analysis to measure proximity and accessibility indices. Statistical techniques such as ANOVA and multiple regression analysis will test for significant differences and predictors of green space access between regions. Qualitative data from interviews will undergo thematic analysis, guided by the Theory of Environmental Justice and the Urban Green Space Equity Framework, to interpret policy influences and stakeholder perspectives. The expected outcome is that substantial disparities in green space accessibility will be evident, with socio-economic and policy frameworks significantly influencing distribution patterns. Variations in accessibility will likely correlate with neighborhood income levels, urban density, and municipal green space policies. This research will contribute novel insights into regional disparities in urban greening, advancing theoretical understanding of environmental justice in urban contexts. It will also develop a comparative framework that can guide policymakers and urban planners towards equitable green space allocation by identifying critical socio-spatial factors. The findings are expected to demonstrate that European cities tend to achieve more equitable green space distribution due to integrated planning policies, whereas North American urban areas may face greater disparities, driven by privatization and zoning practices. The main conclusion underscored by this study is that addressing sustainability and livability in cities requires region-specific strategies that prioritize social equity in green space distribution. Recommendations will include the adoption of GIS-based accessibility planning, community engagement in green space development, and policy harmonization for equitable resource allocation. Finally, the research will suggest avenues for further investigation, such as longitudinal studies on green space investment impacts and the role of technological innovations in enhancing accessibility. This comprehensive investigation aims to bridge knowledge gaps in urban environmental justice and support sustainable urban development practices globally.
