In 2005, for instance, the state received only 88 per cent of usual rainfall, the lowest in the past five years. As a result, the agriculture sector saw de-growth of nearly 14 per cent, with per capita income, falling 1.5 per cent. That was the year Lalu Prasad's Rashtriya Janata Dal (RJD) lost power in Bihar, after an uninterrupted run of 15 years. Bihar voted twice in 2005 to elect MLAs. The February elections threw a hung assembly but elections held in October-November resulted in heavy reverses for the incumbent. The people perhaps felt the real impact of the fall in farm production in the second half of the year.
"To say a fall in agriculture production alone led to the kind of election verdict we had, will be too simplistic, since electoral outcome is dependent on many variables. But a farm fall would have contributed to rural distress. It would have impacted the subsistence of a large number of people living in rural areas, as fall in agriculture production tends to push up prices of food items. As there is a lack of an alternative, a depressed agricultural sector tends to have a cascading effect," argues N K Chaudhary, economist and former principal of Patna College.
Incidentally, in 2010, when Bihar went for assembly elections, was a drought year, too, as the state received only 67 per cent of the normal rainfall, the lowest since 2001. But there was no resultant fall in farm output. The sector, in fact, grew by a whopping 20 per cent in 2010-11. The incumbent, Nitish Kumar of Janata Dal (United), this time in coalition with the Bharatiya Janata Party, came back to power with a thumping majority.
"The depressed economic condition in rural Bihar forces people to migrate. It is the group consisting of small farmers and landless labour, which sends more people outside the state. In political terms, this group is more likely to vote for non-NDA (National Democratic Alliance led by the BJP) parties. A Dip in farm production means likely loss of votes for Lalu or Nitish due to migration of their likely supporters," observes Rakesh Ranjan of Patna University who has been associated with the Centre for the Study of Developing Societies (CSDS) and has been doing election surveys for many years now.
Incidentally, in the 2014 Lok Sabha elections, of the nine seats that non-NDA parties won in the state, eight received much more than the average rainfall, both in 2013 and 2014. It could, then, be safely assumed that the farm sector would have done well in those areas.
