dc.description.abstract | Most drought studies have been dependent on limited rainfall data that is available in most parts
of Tanzania. The new development in space technology, especially satellite derived products
now provide new opportunities that can be used to study space- time characteristics of drought.
Thus the main objective of this study is to assess meteorological drought severity using various
indices over Dodoma region.
Rainfall data used in this study was obtained from the Tanzania meteorological agency and was
from 1985 to 2012 for Dodoma meteorological station and Hombolo agro meteorological station.
The method used in this study includes the calculation of drought indices such as standardized
precipitation index (SPI) from R- program and the drought severity index (DSI) derived from
rainfall records using some standardized statistical methods. The two indices were compared for
improving early warning system.
The study has shown that drought indices based on SPI and DSI can provides realistic estimates
of drought conditions. There were however some challenges in using these indices because they
are mostly rainfall dependent.
The study has provided a way of assessing the worse drought periods by means of SPI as well as
DSI that could be used for regional drought monitoring in order to improve the early warning
system. | en |
