La géographie des déchets au défi de l’organisation territoriale au Brésil et en France

Abstract : The impact of all kinds of waste inevitably increases as the world's population becomes more urbanized, and as initiatives to consider it as a resource or to reduce its quantity multiply. First, we seek to demonstrate that waste constitutes a complete geographic and social object, not only because it reveals how the relationship between Man and Earth functions, but also because spatial analysis of related activities linked to waste collection, disposal, and recovery, indicates how this object enters territories. Thus, in France and in Brazil, a new system of governance emerged in the 1970s, placing waste treatment in a particular treatment in municipal cooperation, applying both technical and social solutions, such as the integration of wastepickers work in recycling. However, efforts by public, private, and associative agents are generally insufficient to limit impacts and to value correctly the garbage produced in cities. Using Geography tools, we seek to evaluate solutions put into practice in three case studies (in Rio de Janeiro and Paris) in order to understand how the actors are organized in their territories to face environmental, economic, and social challenges put forth by the disposal of urban waste, since formal and informal circuits continue to coexist. Finally, the geographicity elements of this object stand out clearly in terms the treatment of temporalities and the interweaving of scales, but also by the expansion of responsibilities in the public space, at all levels, from individual scales to institutional superstructures.
