Abstract
Drought is a recurring event in peninsular India and has large scale socio-economic impacts. In order to reduce the drought impacts, a continuous monitoring of drought characteristics is required. This study is aimed at estimating drought characteristic- mainly drought area and aerial deficit- in the state of Maharashtra. A large variation in the rainfall amount was observed across the state. It was found that central part of the state, being on the leeward side of Western Ghats, is the worst drought hit area. Apart from this, the eastern part of the state was also under considerable water stress. The results obtained from statistical analysis were converted to spatial domain using ordinary kriging, in order to demarcate zones of varying drought severity.
