Uganda continues to face significant structural deficits in public service delivery, including inadequate healthcare infrastructure, low school enrolment rates, limited access to clean water, and weak governance frameworks, which collectively constrain inclusive development. Donor-funded programs have emerged as a critical mechanism for bridging these gaps, mobilising financial and technical resources to supplement government capacity.
