Abstract:

Drought analysis offers a better scope for predicting the occurrence of drought to help in crop planning in rainfed regions. In view of this, an attempt has been made to evaluate drought reoccurrence patterns of weekly, seasonal, monthly and annual rainfall according to the severity, based on 17 years (2000-2016) data of Mungeli, Chhattisgarh. The observed data shows that 38th and 39th standard meteorological week experienced maximum (58.82 %) disaster drought and followed by SMW 24th and 26th. It was also observed that no drought condition was experienced maximum 52.94 in SMW 32nd.From the monthly rainfall analysis, it was found that June, July August and September months of monsoon season experienced 5.88, 35.29, 35.29 and 17.64 % mild drought. Moreover, it is experienced that maximum disaster drought (88.23 %) in the December month while August month did not experienced any disaster drought. The climatic seasonal analysis depicts that the monsoon season experienced 58.82, 29.0 11.76 and 0 % of no drought, mild, severe and disastrous drought, respectively. The kharif and monsoon season of the region are experienced zero percent disastrous drought and they have 41.1 and 58.8 % of occurrence possibility of no drought condition thus in these seasons rain water is sufficient for crop planning, but there is frequent drought in region. The severe drought is experienced in the year 2000 and 2016. Therefore, 07 out of 17 years (years 2006, 2008, 2009, 2010, 2011, 2012 and 2015) experienced mild drought years for the 7 years. There was a continuous drought from 2008 to 2012 and 2015 to16. Thus some major steps are needed for assuring the irrigation in rainfed regions. Also the possibilities of occurrence of drought are high in rest of the seasons and as observed every year more than 75 % of the rainfall occurs in the monsoon season, so there is a need of water harvesting at the time of monsoon season for crop planning of rabi season for at least one or two supplemental irrigations.
