Within Ghana and other rapidly expanding African cities, informal settlements continue to grow, absorbing millions of urban residents, expanding into flood-prone corridors, encroaching on waterways, and stretching the limits of city infrastructure, even as governments launch upgrading programmes, secure development financing, and produce national housing policies designed to address the problem.
The persistence of the phenomenon, despite decades of intervention, is not an accident. It is the predictable outcome of a set of structural conditions that policy frameworks have consistently misdiagnosed, underfunded, or politically avoided.
A systematic review drawing on 92 peer-reviewed studies found that informal settlements emerge primarily as a consequence of rapid urbanisation and serve as “stark indicators of urban poverty,” driven less by the choices of individual settlers than by the inability of formal housing markets to produce affordable alternatives at the pace and price that urbanising populations require.
The settlement itself is not the problem. It is the symptom.
Across sub-Saharan Africa, residents of informal settlements comprise a significant share of the urban population and are disproportionately vulnerable to climate-related hazards, including flooding, poor sanitation, inadequate drainage systems, and environmental degradation.
These vulnerabilities are becoming more pronounced as climate change intensifies rainfall variability and extreme weather events.
Urbanisation has advanced at a pace that has outpaced the ability of infrastructure providers and local authorities to match. Housing delivery, sanitation services, drainage networks, and transportation systems have all lagged behind population growth, particularly as rural-to-urban migration continues to place pressure on cities that were never designed to accommodate such rapid expansion.
In Ghana, the gap between the scale of the challenge and the capacity of policy responses has become increasingly apparent.
Research into urban informal settlements has identified inadequate funding as one of the principal obstacles to successful upgrading programmes.
However, financial constraints represent only part of the challenge.
Community-level factors, including ethnic diversity, varying local attitudes toward external interventions, and the absence of formal land ownership documentation among residents, frequently complicate implementation efforts and reduce the long-term effectiveness of policy interventions.
Land tenure remains one of the most critical barriers.
Residents without documented ownership or recognised occupancy rights are often excluded from formal upgrading programmes, unable to access housing finance, and reluctant to invest in property improvements due to uncertainty about future displacement.
Without secure tenure, residents have little institutional incentive to participate fully in long-term development initiatives.
Research examining informal settlements in Greater Accra has also highlighted a recurring weakness in policy design.
Many interventions rely on “blanket and generalised” approaches that fail to account for the social, cultural, and economic differences between settlements.
Communities with different histories, leadership structures, migration patterns, and land arrangements are frequently treated as though they face identical challenges.
Yet the distinction between migrant-dominated settlements and indigenous communities, for example, can significantly influence land governance, infrastructure priorities, and the willingness of residents to engage with formal planning processes.
Secondary cities are experiencing similar dynamics.
Research conducted in Sunyani found that customary land authorities and informal land markets are playing a central role in urban expansion, often filling gaps left by formal land administration systems.
Many residents and business operators acquire land through informal arrangements and possess limited awareness of the regulatory structures that formally govern urban development.
The result is a parallel system of land allocation and settlement growth operating alongside, and sometimes in place of, official planning institutions.
Researchers consistently argue that successful urban upgrading requires more than infrastructure investment.
Recommendations focus on “fair and equitable urban planning” that includes underprivileged communities as active participants rather than passive recipients of policy decisions.
Improving resilience requires governance systems that incorporate local knowledge, recognise community leadership structures, and create meaningful opportunities for residents to influence planning outcomes.
The failure of many upgrading programmes is therefore not primarily technical; it is participatory.
Communities that do not understand, shape, or develop ownership of interventions are less likely to sustain those interventions once external funding, donor support, or project supervision ends.
The policy implication is straightforward, even if politically difficult.
Informal settlements will continue expanding as long as the conditions that produce them remain unresolved.
Unaffordable formal housing, weak land governance systems, inadequate urban planning capacity, insufficient infrastructure investment, and limited access to secure tenure continue to drive informality faster than governments can contain it.
Demolitions do not eliminate those pressures.
Relocation programmes without tenure security merely reproduce them elsewhere.
And upgrading initiatives that treat funding as a substitute for institutional reform often produce temporary improvements rather than lasting transformation.
Ghana’s housing deficit remains substantial, urbanisation continues to accelerate, and demographic pressures on cities are expected to intensify in the coming decades.
Informal settlements are therefore unlikely to disappear.
The more important question is whether governments are building governance frameworks capable of managing urban growth in a way that is inclusive, sustainable, and resilient enough to meet the realities of the cities that are already emerging.
