The fitful pulse of an Indian food staple
The history of consumer price indices for pulses in India’s ordinary shops and bazaars since 2006 January is one of five periods. The first, from 2006 January to 2008 June, is of a rise in some pulse foods, a decline in a few, and little movement in others. The second period is one of a rise in concert from 2008 June to 2010 January, some pulse foods rising very steeply and not others – whole moong did but not whole urad, masur dal did but peas did not, horse gram did but not rajmah.
The third period, from 2010 February to 2011 August, is an overall lowering of the price indices for almost all pulse foods. This happened when the general food price index rose quickly and stayed high – but pulses remained relatively unaffected. That insulation, the fourth period, didn’t last long, from 2011 September till around 2012 May (even shorter for some pulse foods).
The fifth period began around 2011 July for some pulses, and two months later for others, and is continuing. This is a period of volatility in the price indices of the pulses group to an extent not seen in the previous seven years – peas rises but not gram, horse gram and rajmah shot up but raungi and white gram dipped, whole masur and whole moong soared while besan fell and papad remained flat.
The data I have taken from the monthly itemised retail consumer price indices, weighed to be all-India, for industrial workers with their base of 100 being in 2001, and compiled by the Labour Bureau, Ministry of Labour and Employment, Government of India.
At the end of the second quarter of 2014, the spread of price index values for the pulses group of our staple foods is wider than at any time in the last eight years. It is this food group that provides the nutritional balance and is a culturally rich source of protein in everyday meals and popular home-made snacks. The overall price rise these charts graphically illustrate, and the uncertainty about their availability (which is what the recent volatility of the individual index lines show) are evidence of the threat to the nutritional security of many millions of rural and urban households in India.
