Abstract:
In this paper, assessment of meteorological drought has been carried out by standardized precipitation index (SPI) for Western Central Table Land Agro-climatic Zone covering six districts of Odisha, India. Monthly rainfall data of 115 years (1901-2015) for all the six districts of this agro-climatic zone of Odisha were analyzed using SPI on different time scales of 1, 3, 6, 9, and 12-month. Results indicate that mild drought events have the highest frequencies of occurrence followed by moderate drought events for all timescales under analysis in all the districts. The average total frequency of drought of all intensities are observed to be 54.10% out of which mild, moderate, severe and extreme drought will occur with frequencies of 35.5, 9.5, 6.25 and 2.85%, respectively. 49.25% areas of this agro-climatic zone in the state are affected by drought of various intensities out of which the share of mild, moderate, severe and extreme drought is 28.40, 13.28, 5.05 and 2.52%, respectively.
