Investigating people’s levels of subjective vulnerability to change can help elucidate important aspects of adaptive capacity to impacts. This is particularly relevant in coastal communities with high exposure to natural disasters, such as those in the Caribbean region, especially given projections of increased frequency and severity of storms as a consequence of climate change. In this study, Puerto Rican fishers’ perceptions of the effects of climate change on their fishing activity were compared before and after two major hurricanes severely impacted the island in the fall of 2017. Data was collected through the use of surveys conducted in 12 different fishing communities in Puerto Rico at two different time periods: pre-storms (August 2016 – January 2017) (N = 212) and post-storms (May – June 2018) (N = 75). Results show that fishers demonstrated higher concern in the post-storms period for climate change in general as well as for other environmental changes attributed to climate change, particularly the ...
