Drought analysis in southern highland and central Tanzania
Abstract
Temporal characteristics of meteorological drought were investigated to provide a frame
work for sustainable water resources in the southern highland and central Tanzania These
regions are intensely productive in agricultural activities which makes more important for
drought analysis in order to overcome drought risks. Using Precipitation drought index (pDT)
drought characteristics for the period 1978 to 2008 were assessed using decadal rainfall and
probability drought analysis method were used to analyze drought persistence. Findings
showed that drought category that occurred in both regions were mild (low) and Moderate
droughts, and most of the drought that occurred persisted for only one year except those that
occurred in 1983, 1993, 2003 and 2005 respectively which persisted for at least three years
and caused serious human hazards including, food and Hydroelectric power crisis in most of
the regions.
