Introduction. The negative effects of climate change affect community subsistence

Aim. This exploratory research compares the perception of climate change, as well as the
reduction of social capital and mental health, in two groups of migrants arriving in Italy
from African countries with high or extreme vulnerability to climate change.
Methods. The perception of climate change and the degree of social capital were assessed
with a semi-structured interview. The psychological condition was investigated
