The Impacts of Environmental and Socio-Economic Risks on the Fisheries in the Mediterranean Region

The objective of this study is to investigate the impacts of the environmental and socioeconomic risks on the fisheries in the Mediterranean region from an economic point of view. A balanced panel of 21 Mediterranean countries for 2001-2018 has been estimated by the GLS method, considering heteroskedasticity and correlation among cross sections. The volume of fish landed and landed values have been considered in two models. The results show that increases in sea bottom and surface temperature, H+ ion concentration and salinity threaten the fisheries in the Mediterranean region for the volume of fish landed and that sea surface temperature and salinity negatively influence landed values. In addition, there is an inverse U-shaped relationship between human population and fisheries. Moreover, the Human Development Index (HDI), an indicator of countries' adaptive capacity, has a positive impact on fisheries and indicates that countries can safeguard fisheries by improving their adaptive capacity. Finally, our results strongly show the risk of climate change for the fisheries in the Mediterranean region and that fisheries are adversely impacted by climate change as well as worsening socio-economic conditions in the absence of adaptation plans.

Automated summary

The study investigates the impacts of environmental and socioeconomic risks on fisheries in the Mediterranean region from an economic perspective. Findings suggest that increasing sea temperatures and salinity levels pose threats to fisheries volume, while demographic factors such as population density and Human Development Index (HDI) can also influence fisheries. The research underscores the risks of climate change on Mediterranean fisheries and highlights the importance of enhancing adaptive capacity to protect these valuable resources.
