Population pressure and Agricultural change in Ganga-Gandak Doab


Sushma Parashar

An attempt here has been made to portray the scenario of agricultural change under acute population pressure, accompanied with deriving the benefit of agro bio-diversity in the Ganga-Gandak doab i.e. almost coterminus with Saran district of Bihar. The study region after Independence, particularly after 1961 has consistently registered unbridled growth of the population till 2001 with a cumulative increase of >150%. As a result, the overall density of population has gone up from >500 persons (1961) to >1400 persons (2011) km². The physiological density (persons per km² of the N.A.S.) of population has shown rather faster increase due to the shrinkage in the net cultivated land. Endeavours afoot however, are visible to compensate the aforementioned loss through multiple cropping or say, by increase in the double and triple cropped land with the use of tractors and power-tillers. The crop-structure has also changed over this period. The cereals have shown remarkable increase in areal coverage while the inferior to very inferior millets and pulses have disappeared from the agricultural scene of the doab. As a result, the crop-association now is of lesser number of crops in comparison to its past strength. The fact that population pressure has been reduced to a certain extent by the agricultural development during Green-revolution, is irrefutable. But there is no halt on the growth of population. So, the pressure is to continue in future as well. Hence, the agro-bio diversity available in the doab through the raising of crops in association with poultry, piggery, fishery, goatery and dairy needs to be rationally utilized.
