For climatologists like D. Chalvin, a sudden change in physical environment represents a threat to the somatic integrity of an individual previously well adapted to his physical environment. He can then develop a stress reaction called "Bioclimatic stress". The study of bioclimatic stress is very complex and can be carried out using different methodologies (Gisèle Escourrou, 1988; D. Chalvin, 1985). I wish you can help me identify the one that would be best suited to study it in climate-displaced people.
