About the Cover

The study considered the trend of climate change and demand-supply gap of aquaculture in Nigeria and the role of climate change. The specific objectives were to: describe the trend of demand-supply gap and climate change (humidity, rainfall and temperature) in Nigeria; the study used time series data spanning from 1990-2019. Data on aquaculture demand and supply were collected from the Federal Department of Fisheries. Data on rainfall and temperature were collected from FAO. Humidity data were collected from NiMet. Data for this study were analysed using descriptive statistics such as mean, percentages and trend graphs. The result revealed that the demand-supply gap ranged between 862,653 and 1,892,944 with a mean of 1,427,795 tonnes. The latter represents a demand-supply gap of 92.53 percent on the average. Rainfall ranged between 1046mm and 1596 mm with a mean of 1273.95mm Humidity ranged between 78.4 and 85.00 percent with a mean of 81.27 percent while temperature ranged between 26.180C and 27.850C with a mean of 27.300C during the time period. The KPSS test for unit root indicated that all the variables are integrated of order one and can be stationary at first difference (Ref: Adaji DU. Trend of climate change and Aquaculture Demand-Supply Gap in Nigeria: 1990-2019. Discovery, 2022, 58(317), 378-384).
