Trend in climate variation in Karamoja Sub-region, northern eastern Uganda
Abstract

This study focused at determining the spatial and temporal rainfall and temperature
characteristics in Karamoja with a view of establishing the intensity of climate variability.
The study utilized historical data (1947-1976) and NOAA reanalysis data (1979-2009).Results
show that there is a general long term increase in rainfall totals as well as an adjustment in
drought return period when the 1947-1976 and the 1979-2009 periods are compared. Climate
variability is high (coefficient of variation >35%) with the existence of spatial oddities. Northern
and central Karamoja have relatively more rainy days than southern Karamoja. Variability
in the rainfall onset in Karamoja is greater than withdrawal; whereas rainfall onset may
delay, a temporary rainfall break is observed around the 31st pentad and the cessation
marking the beginning of the long dry season occurs around the 62nd pentad. A time’s series
analysis of temperature shows a general rise in minimum (0.9°C), maximum (1.6°C), and
mean (1.3°C)temperature from 1979-2009. MAM, JJA, SON and DJF minimum, maximum
and mean temperature equally showed a progressive rise in varying degree. This study
debunks the notion that Karamoja is a homogenous semi-arid region. Therefore, it is vital for
planners and decision makers to take into account heterogeneity when executing climate
adaptation programmes.
