ABSTRACT
Urban flooding is a major concern in Sub-Saharan Africa (SSA), due to urbanisation, inadequate infrastructure, and climate change. Many cities lack effective drainage systems, leading to frequent flooding. Sustainable Drainage Systems (SuDS) offer an ecologically sound alternative to traditional drainage methods by integrating natural processes into stormwater management. This study uses a thematic analysis of peer-reviewed sources to examine the behavioural, institutional, economic, and technological barriers to SuDS adoption in SSA. Findings reveal deep-rooted constraints, including low public awareness, governance fragmentation, limited financing, and technical capacity gaps. Despite these challenges, opportunities exist in the form of community engagement, policy reform, innovative financing, and technological advancements. Case studies from within SSA demonstrate promising outcomes. The study concludes that overcoming these barriers requires locally adapted, multi-sectoral approaches. The findings offer practical insights for urban planners, policymakers, and infrastructure stakeholders aiming to enhance flood resilience and promote sustainable urban development across SSA.
