We have sought to develop a line of research on the Solidarity Economy through the perspective of constructing new economic and democratic spaces on the basis of the understanding that democracy is not built only through a political bias. The everyday practice of radical democracy, made possible by forms of economic self-management, introduces a new social behavior that extends to others spheres of life. We assume that it is social practices that give rise to spatial relationships. Thus, our aim is to develop a discussion on how diff erent forms of collective organization in the city, including those which, at fi rst, only concern the organization of workers around an economic activity, transform the living conditions of residents to the point of creating new relationships with the place where they live. Understanding territory as a sphere of belonging and appropriation by a community opens a perspective of thinking about a strategy that goes beyond the economic sphere, considering that development should also make worthy the living conditions of the people. In this sense, thinking the Solidarity Economy as a territorial development strategy involves considering that the principles that govern solidarity economic ventures may exceed the production site and guide the life of the community where the Solidarity Economy initiatives are present. Keywords: solidarity economy, territory, social production of space.
