Sociometabolic regimes represent dynamic equilibria of society– nature interactions and are characterized by typical patterns of material and energy flows (metabolic profiles). From this perspective, industrialization appears as a process of transition from the agrarian to the ...

Climate change has been proven to be the ultimate cause of social crisis in pre-industrial Europe at a large scale.
