Islands are uniquely vulnerable to extreme
weather events and food insecurity and have
additional response challenges.
Farmers have a key role in producing domestic
food, which can safeguard food security when
food importation may be challenging.
Nevertheless, in the context of disaster, farmers
themselves may be vulnerable to food insecurity.
●Survey data of 405 farmers (87% response
rate), coupled with biophysical data related to
the hurricane were examined under a social-
●Farmers were asked between May and June
2018 about the months in which their
households had difficulty acquiring food or
Percentages of reported household food insecurity by month
●69% percent of farmers reported at least one
month of low food security in their households.
●31% percent reported 1-2 months of low food
security (immediate food insecurity), 38%
reported 3 months or more of low food security
(persistent food insecurity), while 31% reported
no months of food insecurity.
The distribution of the proportion of responses
by category is shown here. There was no data
for municipalities in gray. Municipalities
grouped in a dark line reported greater
landslides. The dotted line shows Maria's
●A multinomial regression model suggested that
biophysical impacts, but especially social factors, such as
age and restricted access to external sources of support,
were linked to reporting persistent food insecurity.
●Those in the persistent category tended to reside in
municipalities with greater incidence of landslides and
that were close to the hurricane's track. The size of farms
of those experiencing persistent food insecurity tended to
be smaller than the farm size of people experiencing only
immediate or no food insecurity.
●Results suggests that the biophysical impacts of the
hurricane interact with existing infrastructure and social
resources to affect farmer vulnerability and the food
environment in different ways.
Strengthening farmers' adaptive capacity could safeguard their livelihoods, and thus support local agricultural production and food security.
Understanding how people navigate disruptions in the built and natural environment is crucial for better understanding food security outcomes in the
context of disasters. Future studies should incorporate mixed-methods and integrate structural variables for a more nuanced understanding.
