Drought affects agricultural growth by its duration and frequency. Karnataka an agrarian-based
economy, experienced frequent intense droughts in the last two decades. This study analyzed the
intensity and duration of dry spells that occurred in Karnataka between 1990 and 2020 in the spatial
context by using SPI. The Standardized Precipitation Index (SPI) helped in identifying four significant
drought incidents in the last three decades. Mann-Kendall Test was used to identify the trend in the
SPI values. The results showed that the droughts in last decade were more intensive compared to
previous two decades. The duration of recent dry spells got overlapped between two different drought
periods. The northern districts of State get more frequent dry spells compared to the southern districts.
