Assessment of Temperature Variability Effect on Rice Production in Nasarawa State, Nigeria

Cereal farmland production is critical for long-term global food stability. The quantity of cereal cropland production is partly a feature of climatic elements and is linked to climatic variation pulses. As a result, the impact of temperature variability on rice production in Nasarawa State, Nigeria, was investigated in this paper. The Nigerian Meteorological Agency provided daily maximum and minimum temperature data, which were translated into monthly averages, while the Nasarawa State Agricultural Development Program provided annual rice production data. The data was analysed using techniques such as the Linear Multiple Regression Model, coefficient of variance, and spatial data analysis. While both minimum and maximum monthly temperature variations influence rice production in the state, the latter, with a negative impact size of -3.145 and a coefficient value of -191,324.30 metric tonnes, poses a serious threat to rice production sustainability. Because of the negative effect of maximum temperature variations on rice production, Nasarawa State’s rice production is vulnerable to climate variability as maximum temperatures rise. In contrast to the North and West senatorial districts, LGAs in the south senatorial district have more favourable positions for rice production due to less temperature fluctuation. To avoid the negative effects of temperature fluctuations, government and non-governmental agencies, as well as individuals, planning to develop rice farm project(s) in the study region should consider doing so in the South Senatorial District.
