Abstract: Abstract The state of undivided Andhra Pradesh, India, spent around US$ 20 million per annum on drought relief programs during the period 1998–2008. However, till date, no long-term drought plans are in place due to poor availability of information on drought severity at each mandal or county level. For assessing the vulnerability of mandals to different drought intensities, a simple and novel drought severity index called CRIDA Drought Severity Index, named after the affiliated institute, was developed. This index takes into account frequency and intensity of agricultural droughts at mandal level. The frequency and intensity were estimated using average moisture adequacy index (MAI) during the crop growing season for each mandal. The years with average MAI during crop season of > 0.75, 0.50, 0.25, and
