Abstract : The anticipation of the ruptures affecting the territory is one of the privi¬leged topics which enriches research-actions and experiments within the local, more particu¬larly in the Area of the Nord-Pas de Calais and the Area PACA since ten years. By a joint action of mutualisation of information and setting in prospect for the signals, the territory can be released from a mainly reactive posture to the profit of an pro-active atti¬tude vis-a-vis its future ruptures (epidemics, floods, installations, employment etc). However, this one is a fact acting on the local in an exponential hubbub of information and signals which darken the horizon of the territorial project. The volatility of the projects and the brutal changes of the fundamental reference marks within the place of life, create a doubts, even of vacuum, where all one each one wonders about the nature of the heritage symbolic system which he wants to defend. The decision makers of the elected officials local or persons in charge for organization have some sorrow, to feed a political, economic or social reflexion, to treat this exponential flow of information. Each one seeks in the council of the other, the salutary warning which will prevent the storm while being tested in same time to play the soothsayers of a dubious future.
