Social Sustainability in Metropolitan Areas: Accessibility and Equity in the Case of the Metropolitan Area of Valencia (Spain)
2018
Pitarch-Garrido, Maria-Dolores
By definition, sustainable development includes environmental, economic and social dimensions. Scholars have paid little attention to the latter, although greater interest has been seen in recent years due to the growing strength of the idea that development without equity is not development. Within this context, moreover, urban spaces present complex structures that make it difficult to address sustainable development goals without adequate territorial planning. The aims of the present article are twofold: to expound a conceptual line of thinking to define the social dimension of sustainability—while aware that it is inseparable from the other two—and to propose a simple measurement method based on the accessibility of public services. This method uses time-distance as the measure through which to understand socio-spatial equity. It is based on using GIS tools for a case study—in this case, the city of Valencia—and on the concept of spatial equity as the basis of social sustainability.
