1b) but first, a few points need clarifying.įirst, it is crucial to ensure that terminology is firmly tied to underlying processes. A schematic classification cube can be used to compare these and other events (Fig. According to this definition, the Black Death pandemic and early COVID-19 lockdowns caused anthropauses, while the Chernobyl disaster was followed by a regional human pause. Importantly, I recommend that the label anthropause be reserved for events of high magnitude at continental to global scale (and of any duration Fig. ![]() I propose a basic classification scheme for human pauses based on how widespread (spatial extent), sustained (duration) and pronounced (magnitude) reductions in human mobility are (Fig. An analogous scheme can be used to classify human pulses, including anthropulses. Placement of events in this conceptual diagram is indicative only, and resolving the magnitude scale quantitatively will require empirical benchmarking. Early COVID-19 lockdowns and the Black Death pandemic can be classed as anthropauses as they were events of high magnitude at global and continental scales, respectively (red balls) it remains to be determined, however, if subsequent COVID-19 lockdowns (greyish-red ball) of relatively reduced magnitude, spatial extent and duration also fall within the anthropause space. b | A classification scheme places human pauses along three main axes: magnitude (that is, reduction in human mobility relative to contemporary baseline levels) spatial extent (the four categories depicted here correspond tentatively to areas spanning approximately 10s, 100s, 1,000s and 10,000s of kilometres) and duration. ![]() An anthropulse is the reverse phenomenon that might directly follow an anthropause. A | An anthropause is an unusual, substantial, temporary, continental- to global-scale reduction in human mobility (top), which can cause a variety of environmental responses (bottom), with beneficial, adverse or no conservation impacts (conceptual diagram).
