In a peripheral region, the process of spatial valorization/appropriation is vigorous. It can be inscribed in and explained by the two following degrees of the sociospatial scale : the space of heartland-hinterland relations, on the one hand, where the impetus comes from the core and finds its spatial expression via State and technocracy. On the other hand, we find the space of urban-rural relations where urban bourgeoisies develop and impose new spatial practices. The use of space for social production implies means, and purposes induced by the logic of the System of production and by its conditions for survival. The organization of contrast is one of the spatial forms which is commanded by this logic.
