ABSTRACT

Nigeria fisheries and aquaculture industries are under much pressure from climate change. The Sustainable Development Goals (SDGs) of poverty alleviation, eliminating hunger, excellent health and well-being, tackling climate change, and life below the ocean are all in grave danger of being missed by Nigeria. Hence, the study examined the impact of climate change on aquaculture and fisheries production in Nigeria. Data used was gathered from FAOSTAT, Statista, and the World Development Indicators databases from 2009 – 2022, including aquaculture productivity, temperature, rainfall, and CO2. Descriptive statistics, Granger causality, panel unit root, correlation test, and Fully Modified Least Squares (FMOLS) were employed to analyze the data. The result of descriptive statistics shows that no outliers among the variables. VIF demonstrates that the variables are not collinear. The unit root of stationarity utilizing PP and ADF methods shows that the variables have a mixed order of level I(0) and a first difference order integration I(1). FMOLS estimated results show that rainfall (-0.694) was statistically significant at the 5% level. CO2 (1.778) was statistically significant at the 1% level. Correlation reveals a strong relationship between CO2 (0.903) and aquaculture productivity. CUSUM and CUSUMSQ tests demonstrate the stability of the values at 5%. As the Granger causality test shows, all variables are susceptible to short-run causation. The study consequently recommends severe rules to prohibit intensive aquaculture in areas with significant CO2 sequestration; apply effective adaptation strategies; improve management processes; and invest in climate-resilient systems.
