RESUMEN El progreso y el desarrollo urbano son practicas de despojo del territorio de los moradores. Esta, al igual que en la colonia, busca arrebatarles la tierra a los habitantes mas desvalidos con la excusa Neocolonial de renovacion urbana y rural. Pero en la realidad lo que se hace es que se les expropia y empobrece al no pagarles o hacerlo deficitariamente por plazos, sin indemnizarseles y sin ser reubicados, para marginarlos y expulsarlos. Lo anterior se evidencia dentro de la investigacion denominada “Implicaciones psicosociales, economicas y territoriales de los proyectos de desarrollo urbano”, Medellin (Colombia), con una metodologia etnografica de investigacion accion participativa. ABSTRACT Progress and urban development are practices of dispossession of the territory of the inhabitants. It is just like in the colony it seeks to seize the land from the most disadvantaged inhabitants with the Neocolonial excuse of urban and rural renewal. But in reality, what is done is that they are expropriated, impoverished by not paying them or doing so in deficit, for terms, without compensation and without being relocated, to marginalize and expel them. The above is evidenced in the research called “Psychosocial, economic and territorial implications of urban development projects” Medellin (Colombia) with an ethnographic methodology of participatory action research.
