Green revolution versus instability in foodgrain production in India

Abstract: India has exhibited a remarkable growth in total foodgrain production during the last 40 years. Total foodgrain production has increased by 236% with an annual growth rate of 2.74% during the period 1950|51-1989|90. Average production increased by 72% between periods 1950|51-1965|66 (pregreen revolution) and 1966|67-1989|90 (green revolution). These increases have been accompanied by higher instability and risk in production of certain crops. This study applies variance decomposition procedures to time series data on foodgrains to analyse the sources of instability. Statistical identities have been used to provide an exact decomposition of the components of change in mean and variance of production. The coefficient of variation and variance of total foodgrain production increased by 6.97 and 239.65%, respectively, between the two periods. © 1993 John Wiley & Sons, Inc.
