This dissertation work has as object of research the construction of means of reappropriation and collective management of public space through the projects of community urban gardening in the city of Rio de Janeiro. In this sense, the central objectives of this study are to identify the tensions in the movement of reappropriation of public space through urban gardens. As well as, to analyze the challenges and possibilities of the collective management of this space from the tactics, techniques and plans of action elaborated by the community arrangements that participate in the gardens. We refer to the singular forms of making and thinking the city that exist in these initiatives and that, in a creative and multitudinous way, sow the common as an important political horizon in the struggle for a more democratic, cooperative and fraternal production of space. The purposes of this investigation, in turn, lead us to a problem that is ongoing in the present moment of the metropolis everyday life and that is built based on the unequal relations of spatial domination and appropriation that are established between different social groups. In times of space metropolization, the reorientation of State policies based on the economic determinations of the real estate-financial market culminated in the elaboration of new government guidelines in Rio de Janeiro, now expressed under an order that homogenizes, fragments and hierarchizes the uses and representations of the city. In view of the strategic and market rationality of these hegemonic actors, the process of social segregation based on private land ownership has consolidated itself as a general trend in the territory. And the public space, inserted in this privatist logic of territorial control, is in a progressive metamorphosis: incorporating elements that limit its conditions of accessibility and alterity. However, while many of the city s contemporary transformations take place in tune with the dominant order, others point to signs of significant disruptions to the status quo. From this perspective, in recent years, the collective management initiatives of the public space in Rio de Janeiro have multiplied through community urban farming. In a peculiar way, such initiatives reveal many existing openings for the exercise of life in common, a life that is cultivated together with the Other.
