dc.description.abstractAn attempt has been made in this study to examine the following objectives. To investigate the trends in rainfall and temperature of Chhattisgarh from the beginning of the 20th century. To identify the spatio-temporal linkages with the large circulation modes. The present study was conducted in 16 districts of Chhattisgarh as it is formed in Nov. 1st 2000. Chhattisgarh is an agriculture based state and approximately 60% of agriculture is heavily dependent on natural factors such as rainfall and temperature. Chhattisgarh is in central part of India which is also as in land locked situation. The temperature and rainfall trends are analyzed for meteorological data of 16 districts of Chhattisgarh over 102 yearsbetween 1901-2002. The long term change in temperature and rainfall has been assesses by trend analysis. The trend in mean maximum temperature (MMAX), mean minimum temperature (MMIN) and total mean rainfall (TMRF) with separate season as Monsoon, Pre-monsoon and Post-monsoon are confirmed by the Mann-Kendall trend test. It is observed that districts Dantewada, Bastar and Kanker showed highest significant trend mean minimum (MMIN) and mean maximum (MMAX) temperature for the 20th century in present study. District Dantewada showed highest increasing trend as 0.9897° C for the last century known as 20th century duration at (1901-2002). According to Intergovernmental panel on climatic change (IPCC,[5]) reports, the surface temperature of the earth has risen by 0.6_+ 0.2°C over the 20thcentury. Also the last 50 years, the rise in temperature has 0.13+_0.07°C per decade. As the warming depends on emission of GHGs in the atmosphere, the IPCC has projected awarming about 0.2°C per decade. The highest decreasing precipitation showed by Koriya -109.36mm for last 20th century. Not only Koriya all other 15 districts also showed decreasing trend. Chhattisgarh state is in decreasing precipitation pattern which expected to adversely affect its natural resources, forestry, agriculture and extreme events. Overall mean maximum (MMAX) and mean minimum (MMIN) temperature showed increasing trend which is statistically significant at 5% level of significance whereas total mean rainfall (TMRF) showed decreasing trend which is also statistically significant at 5% level of significanceen_US
