Abstract :

<p><p> Rayalaseema region comprising the four districts of Ananthapur, Chittoor, Kadapa and Kurnool is located in the southern part of Andhra Pradesh. Frequent drought occurrence from the 19th century onwards is the prime cause of backwardness of Rayalaseema region, depressing its economy to stagnation and poverty. Chronically drought prone Rayalaseema region has become a foster child of the state Andhra Pradesh. The climate in Rayalaseema region is mostly dry with very low annual rainfall. The subject field of assessment of drought in Rayalaseema therefore becomes very significant to plan effective management of the limited water resources available.. Drought indices play a substantial role in drought assessment. In the present survey, district wise drought probabilities over Rayalaseema districts of Andhra Pradesh, which are severely prone to droughts, has been established using meteorological drought indices. The meteorological drought indices are: Deciles,Standard Precipitation index(SPI),Reclamation Drought Index (RDI). Such type of information would be a beneficial instrument for planning roles and for input in modelling.</p></p>
