Title : Study of drought in Haryana on the basis of drought indices

Abstract :

Drought is one of the most disastrous phenomenon as it inflicts untold numerous miseries on crop production and human societies. Haryana state lies in Trans-Gangetic plain and lies between 27⁰ 39’ N to 30⁰ 55’ N latitude and 74⁰ 27’ E to 77⁰ 36’ E longitude with an area of 44,212 km2 i.e. 1.3 % of the total area of the country. The study was carried out in the Department of Agricultural Meteorology, CCS HAU Hisar. The aim of study was to find out the frequency of drought in Haryana during kharif season of 21 districts, rainfall data were collected from India Meteorological Department for a period of 1987 to 2016. To identify the drought year’s two drought indices i.e. SPI and rainfall deviation from normal as given by IMD were used. On the basis of SPI values Ambala and Mewat in eastern zone and Fatehabad and Rewari in western zone are more prone to moderate drought, whereas Sonipat and Hisar has more chances to experience severe drought based on their past study. Kurukshetra and Kaithal seems to be safer in terms of their proneness to sever drought as they never experienced SPI based severe drought condition during the study period. Another criteria i.e. IMD’s rainfall deviation criteria of drought frequency reflected that the districts Sonipat, Bhiwani and Rewari have more tendency of getting moderate drought as compared to other districts and Kurukshetra and Kaithal in case of severe drought. In eastern zone of Haryana majority of area was under no drought conditions on the basis of both indices. As drought category is concerned the IMD criterion for drought is more sensitive to ‘Moderate’ and ‘Severe’ droughts and the SPI found more sensitive to ‘No drought’ conditions.
