This present dissertation focuses on environmental policy of nature s commoditization (commodification) like the model of access, use and conservation of nature under the current stage of urbanization that we are experiencing, named metropolization of the space. This conjuncture represents the emergence of environmental issue as a new contradiction of urban problems, related directly to the contradiction society and nature in the context of neoliberal capitalism. Aiming it, we will seek to build some necessary mediations between the Geography and Marxism, in order to demonstrate the epistemological and methodological potential of integration between Geography and the historical and dialectical materialism in the interpretation of these new contradictions, cooperating in a constitution of space s social theory based on the theoretical contributions of political space economy. This conservation and sustainable model based on the expansion of market logic to the nature hides practices of appropriation/space domination, which are class strategies, which seek to ensure the reproduction of the social relations of production. For that, we look forward to identify and recognize the current production of nature as a new space strategy of accumulation and reproduction of capital. The nature, in neoliberalism, has the function of absorbing part of the surplus capital, mainly in a context of crisis like we are living in the current conjuncture. This statement is the starting point so that we can understand he intimated relationships over the new mechanisms of use and conservation (based on practices of commoditization - commodification –, of process of financing and environmental’s privatization) with the processes of accumulation by spoliation.
