Abstract
The "Entre-deux" is defined by Ecrement Bernard as an "interval" of "new multicultural otherness, peaceful and open" at the intersection of territorialities". This work is progressing in its theoretical construction: redefines it as distance-time interface with sufficiently stable environment and space components (topology, morphology, typology, symbolism) for cultural diversity is built and developed. He bases his research through anthropological structures and the phenomenology of space and geopolitics. Intends to work on: the city as laboratory-Entre-deux machine, a typology of cities referred to multicultural otherness, a mapping of the Entre-deux opportunities. Exemplifies the contribution of land use with a borderline case: Rivera (Uruguay-Brazil).
