Large-Scale Urban Developments and the Future of Cities: Possible Checks and Balances

Urban planning deploys large-scale urban development as a preferred strategy in many places around the world. Such an approach to development transforms the urban form, generates new socio-spatial urban relations, and changes planning principles, decision-making and urban power dynamics. This editorial introduces large scale urban development as the current urban policy, discusses possible checks and balances and presents the thematic issue on "Large Urban Development and the Future of Cities.

Urban Morphology and Qualitative Topology: Open Green Spaces in High-Rise Residential Developments

High-rise housing complexes (HRHCs) are a prominent trend in urban development. They generate new configurations of open green spaces, thus creating a new set of human-environment relations and a new constellation of urban landscapes. However, little attention has been devoted by the literature to these new spatial configurations and the urban experience they offer. Focusing on the spaces between buildings, this research article examines the urban morphology of these large urban developments and how they are being experienced by residents. Based on morphological analysis, we propose a set of outputs with which to discern and evaluate various characteristics of these new spaces. Namely, a typology of HRHCs complexes, three evaluation indexes, and a green/gray nolli map. Drawing on morphological analysis, the research discusses the role of green spaces of HRHCs in the experience of residents. We portray different tensions arising from the residents’ experience based on walking interviews and propose how these tensions are connected to the morphology of space. Juxtaposing the morphological and qualitative topological analyses, we focus on the way that different planning aspects of HRHCs’ open spaces might foster everyday use and function as well as attitudes and feelings

Social Sustainability: A New Conceptual Framework

There is a lack of theoretical and empirical studies regarding social sustainability. The literature reveals that the “social” was integrated late into debates on sustainable development. This paper aims to fill this gap and proposes a new conceptual framework of social sustainability. We suggest that risk is a constitutive concept of sustainability and that the contemporary conditions of risk resulting primarily from climate change and its ensuing uncertainties pose serious social, spatial, structural, and physical threats to contemporary human societies and their living spaces. Within the framework of sustainability, we propose that social sustainability strives to confront risk while addressing social concerns. Although we agree that without socially oriented practices, efforts to achieve sustainability will be undermined, as too many gaps exist in practice and theory. Thus, we propose a comprehensive Conceptual Framework of Social Sustainability, which is composed of four interrelated concepts of socially oriented practices, where each concept has a distinctive function in the framework and incorporates major social aspects. The concept of Equity encompasses three dimensions: recognition, which “revalues unjustly devalued identities”, redistribution, which suggests that the remedy for injustice is some form of economic restructuring, and parity of participation, which promotes substantive public involvement in the production of space. These efforts may, in turn, reduce alienation and enhance civility and a sense of community and place attachment. The concept of Safety is the ontological foundation of sustainability in general and social sustainability in particular. The concept refers to the right to not only be safe but adopt all measures of adaptation and security to prevent future casualties and physical harm. The concept of Eco-prosumption refers to modes of producing and gaining values in socially and environmentally responsible ways. The concept of Urban Forms represents the physical dimensions of socially desired urban and community physical forms. Eventually, a desired physical form should promote a sense of community, safety, health, and place attachment, among other environmental objectives
