Abstract

Agriculture in Bihar contributes about 19 percent to state Gross Domestic Product and provides employment to about 70% of working force in rural areas. Rainfall however is erratic to poor and unreliable. Though average rainfall in the State is adequate (1067 mm) but the variation is much higher. However, rainfall during June to September varied by 23 percent, adversely affecting rice production. Comparatively large decline in rainfall is observed in high rainfall area than low rainfall area. About 77 percent districts of Bihar experienced decline in rainfall by 5 to 25 percent and 8 percent of districts by more than 25 percent. The relationship between rainfall (SPI Index) and rice production has been positive in all the agro-climatic zones and highly significant in low rainfall area. It suggests creation of assured irrigation infrastructure in the State for sustainable agricultural production, in general and rice production, in particular. Besides, short duration and less water loving crops / varieties need to be developed on priority basis for sustainable livelihood of farming community in Bihar.
