The transformation of urban boundaries
If yesterday, ZAE and cities coexisted on very distinct territories, the boundaries are gradually fading. The activity zones, once peripheral, are today caught up in the urban fabric, without a clear dialogue being established between these different spaces. These zones, which seemed frozen in their land, are now faced with a challenge: reinventing themselves in an urban system in full mutation (treatment of fringes, inter-neighborhood links, ZAN and land availability) while integrating the rapid transformations of work (structural changes in employment, consumption patterns, etc.) and productive sectors (in terms russia phone number list of sectors, governance, new uses, waste management/reuse, decarbonization, etc.).
Contemporary tensions and paradoxes
On the one hand, a gradual degradation of the buildings of the ZAE, where artificialization and new construction are less restrictive and costly than optimization on site. This model, based on unlimited land consumption, does not encourage the maintenance of existing ZAE. This mechanism is proving difficult to stop for communities, since land is essentially under private control;
On the other hand, the necessary reduction, or even stopping, of the artificialization imposed by the ZAN – now TRACE – while maintaining the objectives assigned to the ZAE: supporting employment in the territories, maintaining and developing local businesses.
