This project launches out with the hypothesis that, in order to tackle the normative problems involved in the redress of urban inequality and exclusion, we need to gain a spatial perspective on the idea of justice. Such approach cannot limit itself to distributive or recognitional aspects, but it should include the praxiological issues that empower the individuals as functional social agents in an urban context. Rather than conceiving of collective action merely as a strategic game for the rival consumption of limited goods (like urban space or services), we should broaden the theoretical scope to consider the nature of common pool resources in the city, the dynamics behind their material and symbolic production, and the forms of social exclusion based on spatial factors.
