Present analysis was carried out for two different period‟s i.e., pre global warming period
(1931-1970) and post global warming period (1971-2010) to find out the changes in
seasonal and annual rainfall of 17 districts of Chhattisgarh. Results revealed that there are
changes in monthly and seasonal rainfall distribution in different districts between pre and
post global warming period. When the per cent deviation was examined there was 35%
decline in annual rainfall in Mahasamund followed by Raigarh (29%) and least decrease
was observed at Bastar (6%) followed by Korba (7%). Variability in annual rainfall during
pre and post global warming periods indicated that the highest increase in CV was noticed
in Raigarh district where the CV increased from 18 per cent to 30 per cent during post
global warming period and in Rajanandgaon CV decreased from 29 to 22% during post
global warming period. From the analysis of suitability of rice cultivation under rainfed
condition based on the distribution of rainfall that during post global warming none of the
districts was highly suitable for rainfed rice cultivation. The worst affected district is
Mahasamund followed by Raigarh and Narayanpur. These districts came under category 1
(highly suitable for rainfed rice cultivation) during pre-global warming period and during
post global warming period rainfed rice cultivation no longer suitable. Immediate crop
diversification with other suitable crops (less water requirement and short duration) in lieu
of rainfed rice and also popularizing water/soil conservation technology like On Farm
Reservoir (OFR) and System of Rice Intensification (SRI) should be taken in order to
avoid further degradation of ecosystem.
