The study the drought pattern during pre and post global warming behind for different districts of Chhattisgarh the drought pattern in the back drop of climate change due to global warming was examined. It is very clear from the analysis that the number drought years in a 40 years period had drastically increased during post global warming period (1971-2010) as compared to pre global warming period. This a clear evidence of the impact of regional climate changes due to global warming on the rainfall pattern in all the districts of Chhattisgarh state. Studies are also made to assess the impacts of drought at seedling, vegetative, reproductive and at all stages on the productivity of rice in 4 districts viz. Raipur, Bilaspur, Jagdalpur and Ambikapur districts. From this analysis it was found that due to seedling stage drought the yield loss of rice in different districts varied from 6.3 to 22.7 percent. In case of reproductive stage drought the yield loss varied from 20.2 to 41.1 percent in different districts. When drought at all stage was examined the yield loss varied from 34.1 to 57.4 percent. Thus, in Chhattisgarh state drought incidence has become a regular phenomenon during post-global warming period and there is a considerable and significant impact on rice productivity. Thus, the rice cultivation in Chhattisgarh had become risky under rainfed conditions and therefore the government is recommending crop diversification in these unproductive areas.
