My book manuscript, titled Crosscurrents of Risk: Navigating Changing Climates, Health, and Conservation in Dominican Seascapes, addresses the risks inherent in daily lives of people who dive deeper into changing seas, contending both with shifting ocean ecologies and restrictive conservation policy. Based on two years of ethnographic field research in a northwestern Dominican fishing community including participant observation and in-depth interviews with diver fishermen and conservation officials, my manuscript makes the case that the overlapping experiences of bodily risk and environmental vulnerability illuminate how those on the front lines of changing climates are also those most marginalized by prevailing conservation discourses. This project speaks to critical issues in the relation between human and environmental health, maritime studies, and Caribbean colonial residues.
