Territorial organization covers up socio-economic costs imposed behind the scène on users. Taken as a part of urban renewal, these costs mean that those who decide on territorial appropriation and town and country planning do not really care much about human factors. With the help of notions such as territoriality and scale, geographers dealing with this problem can analyse such a situation thoroughly and from a critical point of view. They then draw up an ecological scheme, which will allow them to redefine the non-alienating relations that man must maintain between himself and his physical and human environment.
