The growing proportion of human populations living in urban areas, and consequent trends of increasing urban expansion and densification fuel a need to understand how urban form and land use affect environmental quality, including the availability of urban green spaces. Here we use Sheffield as a case study of city-wide relationships between urban green space extent, quality (vegetation cover and tree-cover), and gradients in urban form and topography. The total area of buildings and length of the road network are equally strong negative predictors of extent of green space, while the former predictor is amore important negative influence upon green space quality. Elevation positively influences extent of green space but negatively influences tree-cover. In contrast, slope of terrain positively influences green space quality and is the best predictor of tree-cover. Overall housing density is a more important negative predictor of extent of green space and tree-cover than the densities of individual housing types. Nevertheless, the latter are more important influences upon levels of vegetation cover. Threshold effects of densities of different housing types suggest opportunities for optimising green space quality, with implications for housing policy. Variation in ecological quality of green space may partly reflect different historical intensities of industrial activity.
Functioning public spaces, as ‘public’ political, social, and cultural arenas of citizen discourse, affect not only the citizen’s quality of life, but are also indispensable infrastructure in democratic societies. This article offers a nuanced understanding of Iranian women’s usage, feelings, and preferences in public spaces in present-day Tehran by not simply importing Western theories that sustain distinctions between traditional and modern women, but instead by hearing women’s stories. This article raises concerns related to the gender identities, the politics of space, and design of these places. Meidan-e-Tajrish, Sabz-e-Meidan, and Marvi Meidancheh in Tehran accommodate an ethnographic visualization of gendering space. The process by which Iranian women attach symbolic meanings to those public spaces offers insight into the mutual construction of gender identities and space politics. The contrasting urban locations, different design styles, and distinct social activities provide an excellent comparison between the selected public spaces. Findings suggest caution in using gender as an essential category in feminist geography research to better represent the diversity of experiences in public spaces. Binary categorization of modern versus traditional, secular versus religious, public versus private, and male versus female in urban studies should be carefully validated as Iranian women’s lived experiences challenge the homogenizing Western theories, particularly the predominant critics of modern public spaces in North America. The research process also highlights the benefits of geo-visualization in understanding the complex interaction between gender identities and the built environment.
