Abstract:
Climate change is a natural phenomenon but the rate at which it is changing is alarming and it is mainly due to anthropogenic causes. Agriculture of Chhattisgarh is mainly dependent on rainfall and its distribution. Therefore, the present study has been carried out to analyse the variability and trend of rainfall and rainy days using daily actual rainfall data from 1989 to 2019 which was collected from the Department of Agrometeorology, IGKV, Raipur. Variability of rainfall and rainy days was statistically analysed and trend analysis was worked out through Mann-Kendall test. Highest variability in annual and south-west monsoon rainfall was found in Bijapur district and for north-east monsoon variability was highest for Sukma district. The number of rainy days was found stable in Bastar district. Annual rainfall and south-west monsoon rainfall showed significant increasing trend for Bastar and Bijapur districts.
