Trend Variation of Cassava and Rice Consumption in Nigeria: A Trend Analysis Approach

摘要

This study was carried out to determine the trend, growth rate and direction of growth of cassava and rice consumption in Nigeria between the periods of 1970 - 2016. Secondary data were sourced from Food and Agriculture Organization Statistics for thepurpose of analysis. Trend analysis was employed to make out if there exist a drift in growth of a variable over the period of time. The result showed that the trend of cassava and rice consumption were generally on the increase over the period under study with cassava and rice consumption increasing at a point in time at the observed rates (instantaneous growth rate) and also increased over a period of time as observed respectively (compound growth rate). However, the result showed a significant change in the trend of consumption of cassava and rice with coefficients (0.3451 and 0.4211) which were statistically significant at 1% probability level (P < 0.01), indicating an accelerated growth in cassava and rice consumption. Due to the general increasein trend observed, the study recommends effort by the government and private sector towards increasing the production of these crops in order to contain this growing demand.
