It refers to “a process of transformation in which a system moves from one system of equilibrium to another”.
The transition is therefore not a simple adjustment but a fundamental and total reconfiguration of the functioning and the organization of the system. Like the demographic transition, for example.
This transformation affects the technological, economic, ecological, socio-cultural and institutional sectors at the same time. And changes in these sectors are mutually reinforcing.
The transition is therefore characterized by a gradual and profound change in models of society over the long term. It is a process that cannot be fully mastered since it is part of a complex system that escapes planning.
