ABSTRACT

The study focused on the effect ofclimate change on agricultural productivity in Nigeria spanining from 19 to 8. The employed the Ordinary Least Square, Unit Root test and Cointegration test to eva uated objectives. Thus, revealed that rainfall and temperature change both have a negative and significant impact on agricultural output in Nigeria. Also there exist a long run relationship between climate change and agricultural productivity in Nigeria. In addition, the researcher also revealed the econometric criteria (second order) test such as: Heteroscedasticity test; it shows that there is absence of heteroscedasticity in the model and autocorrelation test; shows that thei e is no statistical presence offor autocorrelation. In conclusion, the study also shows that the change in climate has significant effect on agricultural productivity. This is clearly revealed in the rainfall variable however temperature seem not an important variable of climate in determinants ofagricultural productivity in Nigeria economy. Finally, the study recommended that Nigerian government needs to give agriculture serious priority. The current climate change effect can be minimized ifpolicy toward mitigation is geared. Agricultural productivity can be increased and sustained by developing agricultural technologies that are environmentally sensitive. Also agricultural innovation that increase soil nutrient and do not contribute to change in climate should be encouraged.
