Abstract
Projected scenarios in land, population, resource use, land use/cover, climate and
urbanization over the Nile Basin reveal an acceleration and dynamical transitions in nearto-
medium term. These changes have a bearing on water resource dynamics including
the acceleration of the long-held yet hitherto managed conflicts over the Nile waters.
This paper presents a projection of water resource dynamics in the River Nile using the
Upper Nile Water Management Zone (UNWMZ) of Uganda as a reference site. Results
showed variability in sub-catchment discharge into the Upper Water Management Zone.
By 2040, the catchment’s water resources base will decrease by 12.6% whilst gross and
net demand will increase. The projected decrease in the water discharge in the catchment
can be attributed to the anticipated increase in temperatures, a decrease in rainfall and
expected increase in human population in the sub-region. It is recommended that routine
monitoring of catchment discharge is enhanced and intensified. Further, exploration into
the technical and scientific mechanisms that will facilitate effective adaptation to increased
water demand in the catchment should be undertaken in response to the projected increase
in gross and net water demand in the catchment.
