Research Paper of Dr. Pradhan Parth Sarthi to be published in reputed Journal
The research work CUSB faculty Dr. Pradhan Parth Sarthi, Associate Professor, Dept. of Environmental Science (EVS) and his Ph. D. student Mr Sunny Kumar is accepted for published in a reputed Journal. The work of Dr. Sarthi accompanied by Dr. Prabhat Ranjan, a faculty of Department of Computer Science is accepted two days before for publication in very reputed Journal of Pure and Applied Geophysics (Springer International Publishing). In the research the team has suggested decreasing trends in Indian Summer Monsoon Rainfall over EGP and weak low level easterly wind from Bay of Bengal to the EGP are the probable cause.
Providing more details Dr. Sarthi said that the meteorological droughts over the Gangetic Plain of India arise due to significant deficiency of summer monsoon season rainfall for abnormal periods. The changes of summer monsoon rainfall over an area and time over the Eastern Gangetic Plain (EGP) normally triggers meteorological drought which further leads to agriculture and hydrological drought, and widely affects agricultural production as well as water resources over the area. We have recently researched on it and the accepted research work is focused over the agro climatic zones of the Gangetic Plain of India. This research is very useful for agriculture and disaster management over the EGP.
Dr. Parth Sarthi told that to assess meteorological drought (1961-2013) over agro-climatic zones of the states of Uttar Pradesh (UP), Bihar and West Bengal (WB) under the EGP, rainfall data of India Meteorological Department (IMD) and wind data of European Centre for Medium-Range Weather Forecast (ECMWF) is considered.
Over the agro climatic zones of Bihar, the research group analysed the Seasonality Index (SI) and Standardized Precipitation Index (SPI-4) tools. The severe drought-prone zones are found over agro-climatic zones 1(West Champaran, East Champaran, Siwan, Saran, Sitamarhi, Sheohar, Muzaffarpur, Vaishali, Madhubani, Darbhanga, Samastipur, Gopalganj, Begusarai), zone 2 (Purnea, Katihar, Saharsa, Supaul, Madhepura, Khagaria, Araria, Kishanganj) and zone 3B (Rohtas, Bhojpur, Buxar, Bhabhua, Arwal, Patna, Nalanda, Nawada, Jehanabad, Aurangabad, Gaya) of Bihar with more than 50% probability of drought occurrence during the said period.
The study suggests Agro-Climatic Zone 3B of Bihar has relatively high probability of severe droughts in comparison to other zones of Bihar. The relatively high frequency (75% or above) of mild droughts have been persisted over Agro-Climatic Zone 2 and 3A (Sheikhpura, Munger, Jamui, Lakhisarai, Bhagalpur & Banka) of Bihar. Also, more than 60% probability of occurrence of mild drought in all agroclimatic zones of Bihar has been found. A significant decrease in rainfall (for the period of 1961-2013) is found over these zones.
