Abstract:

The average annual temperature and rainfall data for four Agro-ecological zones in Nigeria were analyzed to ascertain their effects on the Nigerian Agricultural sector. The average annual temperature and rainfall data sets for Calabar, Ibadan, Enugu and Maiduguri which were obtained from the Nigerian Meteorological Agency (NIMET), Oshodi, Lagos and the National Bureau of Statistics (NBS) were compared with the Nigerian Agricultural Productivity data from the Central bank of Nigeria Statistical Bulletin, 2006 from the year 1980 to 2005, using the Trend Analysis method of data analysis. It was discovered that the trends from the average annual temperature in the four zones were uniform or constant over the years from 1980 to 2005 (i.e. ranging between 22˚C and 33˚C). When this temperature trend was compared with the Agricultural Productivity trend within the same period, it was clearly seen that the average annual Temperature has no effect on the annual Agricultural productivity in Nigeria. When the average annual Rainfall trends in the four zones from 1980 to 2005 were compared to the Agricultural productivity trend within the same period, there was a correlation between the two variables. This shows that, rainfall has significant effects on the Agricultural Productivity in the country. Areas located in the Southern part of the country which experience more rainfall have increased productivity in crops while the average annual rainfall values increased. Livestock productivity increased as the amount of rainfall reduced in the Northern region (Maiduguri).
