The nature of climate variability in South-Kivu is not yet well understood and how the
impacts of climate variability affect agriculture, especially rice production has not been well
documented. This study aimed therefore at characterizing historical and project future
climate of two selected rice prone areas of South-Kivu namely Kavumu and Luberizi. Rainfall
and maximum and minimum temperatures were considered in the study. Twenty General
Circulation Models (GCMs) were used to project climate for two Representative
Concentration Pathways (RCP=4.5 and 8.5) and for two periods namely mid and end
centuries. Result shows that annual rainfall amount did not significantly vary over the last
thirty years (P<0.05), but the coefficient of variation (CV) has been gradually declining with
years (P<0.05) for both sites. The mean annual temperatures had a gradually increasing
trend for the last thirty years in both sites. However, projected rainfall and temperature are
likely to increase for RCP and periods. The mean increment in minimum temperature (Tmin)
is likely to be relatively higher than maximum temperature (Tmax) in both sites.
