To continue our reflection on habitability, we are lucky today to have two contributions from researchers who, like David O'Byrne, are involved in the HABITABLE project - Linking Climate Change, Habitability and Social Tipping Points: Scenarios for Climate Migration.
We will start the day with Maria F Gavonel's (University of York) paper 'Thinking about habitability through the exploration of thresholds and tipping points in climate migration'.
Maria’s statement focuses on the relationship between the concepts of habitability and social tipping points – namely, tipping points in climate migration. Habitability is defined as the capacity of a social-ecological system (SES) to sustain the lives and livelihoods of its human population, and it accounts for the possibility that environmental change could be life-threatening directly or indirectly.
Maria proposes that two thresholds can be considered as indicators of habitability in the context of climate migration (see the figure "Habitability and its thresholds" in the paper). As environmental conditions deteriorate, the demand for adaptive measures increases, and there is a nonlinear increase in in-situ adaptation. The paper suggests policy recommendations for each level of habitability, and it concludes that the concept of habitability can provide a more granular understanding of the relationship between SES and climate change.
I wonder if we could also go further with a finer description in mobility and migration. Could for example thresholds not only concern the “quantity” of out-migration but also its nature (short vs long term, short vs long distance, etc)?
I highly recommend you to read Maria’s statement and I look forward for a lively discussion!
