Abstract

This study assessed the impact of climate change on fishing activities in some coastal communities in Degema Local Government Area of Rivers State, Nigeria. Data were collected through structured questionnaires and by personal interview from 120 fisherfolks in three communities in the area. Data collected were analysed using descriptive statistical tools. The results reveal a notable climate-related phenomena, such as increased water temperature, extreme weather conditions, sea level rise, and flooding, these were identified as major factors affecting the livelihoods of fisherfolks. By implication, the fisherfolks are the most susceptible to climate change because of their dependence on aquatic organisms as their mainstay. Human activities contributing to climate change, includes: illegal oil refining -"kpo fire" (62%), mangrove deforestation (12%), plastic waste disposal (9%), and the use of chemicals for fish harvesting (15%). The study also revealed significant negative effect of climate change on fishing activities such as decline in fish populations, shifts in species distribution, and disappearance of some notable fish species, which have all affected the livelihoods of fisherfolks and the overall economy of the local community. The findings emphasize the need for effective climate adaptation strategies, improved public health infrastructure, and community education to mitigate the negative impacts of climate change on the Degema fishing community. The study concludes that addressing these challenges will require a multi-faceted approach involving sustainable environmental management, government intervention and targeted public health interventions.
