Abstract
Ghana's major cities flood every rainy season, killing people, destroying property, and displacing thousands. The May 2025 Accra floods killed four people, displaced over 3,000, and rendered major roads impassable — with heavier rains forecast. Yet peer-reviewed evidence confirms that Ghana's flood crisis is not primarily driven by climate change or exceptional rainfall. It is the product of systematic physical planning failure: the unchecked occupation of waterways and floodplains by developers, the chronic exclusion of drainage from road construction contracts, the fragmentation and chronic under-resourcing of regulatory institutions, and the political interference that allows powerful interests to build with impunity in ecologically sensitive areas. This paper analyses the structural and institutional causes of Ghana's urban flood crisis, quantifies property and economic impacts across seven decades of flood events (1955–2025), examines the USD 350 million World Bank GARID remediation programme, and advances fourteen specific policy recommendations spanning physical planning reform, infrastructure procurement standards, institutional strengthening, and property sector regulation. The central argument is that Ghana's flooding is a governable problem, not an inevitable one.

Executive Summary
Ghana's major cities flood every rainy season — killing people, destroying property, displacing thousands, and inflicting hundreds of millions of dollars in economic damage. The May 2025 Accra floods killed five people, displaced over 3,000 residents, and rendered key roads impassable. Yet the evidence is unambiguous: Ghana's flood crisis is not primarily a climate phenomenon. It is the direct product of systematic physical planning failure.
Key Findings
- Ghana has recorded 517 flood deaths and USD 615 million in damages between 1900 and 2021 — making flooding the country's most destructive recurring disaster (MDPI Water, 2021).
- Peer-reviewed research confirms no correlation between increased rainfall and flooding in Accra. In 2017, rainfall decreased but flooding increased — demonstrating that land use failure, not precipitation, is the primary driver.
- 52% of households surveyed identified weak enforcement of land use regulations as the primary cause of flooding in their communities (SN Social Sciences, 2022).
- Road contracts awarded without accompanying drainage infrastructure are a documented, consequential cause — the 2024 Central Region floods that displaced 2,000+ people were directly linked to highway works on the Kasoa-Winneba road.
- Ghana has committed USD 388 million — USD 350 million in World Bank GARID financing plus USD 38 million in domestic allocation — to flood remediation. As of September 2024, only 36.3% of GARID funds had been disbursed and Odaw Channel dredging was 20% complete.
- Political interference in planning enforcement is a peer-reviewed finding — not an advocacy claim. Powerful interests routinely build in waterways and floodplains without consequence.
Key Recommendations
- Establish a National Flood Plain Register — publicly accessible, digitally maintained, updated annually — as a mandatory prerequisite for any development permit in identified flood-prone zones.
- Mandate Drainage Impact Assessments for all road contracts above GHS 500,000, with drainage as a non-value-engineerable contract component.
- Establish an Independent Planning Enforcement Inspectorate reporting directly to Parliament, with powers to investigate and prosecute violations of land use regulations regardless of the political or economic status of the violator.
- The Bank of Ghana should issue prudential guidelines requiring lenders to apply mandatory flood risk adjustments to property valuations used as collateral, with LTV caps reduced by a minimum of 15 percentage points for confirmed flood-prone properties.
- Mandate post-construction drainage maintenance contracts for all roads above GHS 1 million, funded from the original contract budget, with final payment withheld pending satisfactory maintenance inspection at 24 months.

1. Ghana's Urban Flood Crisis: A Perennial Emergency
Between 1900 and 2021, flooding caused 517 deaths, displaced over 5 million people, and inflicted USD 615 million in damages in Ghana — making it the country's most prevalent natural disaster. Yet the evidence is now unambiguous: this is not a natural disaster. It is a man-made one.
1.1 The May 2025 Events
On 18 May 2025, heavy rainfall of 132.20 mm — equivalent to 5.2 inches — struck parts of Greater Accra in a single storm event. Four people died: three in Abokobi and one in Adenta. Over 3,000 people were displaced from their homes. Vehicles were swept away. Roads in Weija, Kaneshie, Adabraka, Adentan-Dodowa, Oyarifa, and parts of Tema were rendered impassable. Power cuts affected multiple communities across the Greater Accra Region.
The Ghana Meteorological Agency (GMet) confirmed the storm system had moved westward from Benin and Togo and warned of continued heavy rainfall — further thunderstorms, clouds, and rain were forecast across Ghana's coastal, middle, transition, and northern areas in the days immediately following the event. The rains did not relent. They rarely do.

1.2 A Pattern, Not an Anomaly
The May 2025 events were not exceptional. They were the latest episode in a decades-long pattern of catastrophic urban flooding that has claimed hundreds of lives and destroyed billions of cedis in property across Ghana. The pattern is so consistent that it demands a structural rather than an episodic explanation:
- June 3, 2015 — the twin fire and flood disaster at an Accra filling station killed over 150 people (official government figure confirmed by President Mahama; Red Cross/IFRC post-event assessment: up to 200 deaths) and caused USD 55 million in direct damage, with estimated reconstruction costs of USD 105 million (World Bank, 2017).
- 2017 — flooding incidence increased despite a recorded decrease in rainfall, conclusively demonstrating that the primary driver is not precipitation but land use and infrastructure failure (Conversation analysis, 2025).
- March 2023 — flooding submerged Kwame Nkrumah Circle; two children died when a building collapsed in Ngleshi Amanfro; a person was electrocuted in floodwaters in Mallam West.
- 2024 — over 2,000 people in Ghana's Central Region were displaced when the Ayensu River flooded, exacerbated by diversion of the river during work on the Kasoa-Winneba highway expansion — a road contract without adequate accompanying drainage provision.
- May 2025 — 4 dead, 3,000+ displaced, with heavier rains forecast.
The cumulative toll from flooding in Ghana between 1900 and the first half of 2021 stands at 517 fatalities and USD 615 million in estimated damages, affecting over 5 million lives (MDPI Water, 2021). The majority of flood disasters and their biggest toll on properties and lives is recorded in Accra — the most urbanised metropolis and both the capital city and major economic centre. Greater Accra Region accounts for over 40% of Ghana's non-oil GDP (World Bank, GARID project documentation).
"We have known that rains will come. What we have failed to do is enforce existing land use plans, uphold environmental laws, and resist the powerful interests who build and live with impunity in waterways and wetlands. Floods in Accra are not a natural disaster — they are a political one."
— Modern Ghana Analysis, June 2025
2. The Structural Causes of Ghana's Flood Crisis
A landmark peer-reviewed analysis of Accra's flooding, published in 2025, reached an unambiguous conclusion: flooding in Accra is caused by poor and uncoordinated land use planning rather than climate change. No correlation was found between increased rainfall and flooding. The dominant cause is land use malpractice — and behind that, institutional failure.
2.1 Cause One: Waterway Encroachment and Wetland Destruction
Between 2008 and 2018, researchers and city residents documented a systematic encroachment on Accra's wetlands — with homes and commercial infrastructure built directly on ecologically sensitive areas that serve as the city's natural flood management system. The Greater Accra Metropolitan Area contains major wetlands including the Densu Delta, Sakumo Lagoon, and Songor Lagoon, all of which are critical for absorbing and managing stormwater. Their encroachment directly translates into increased flood risk for neighbouring and downstream communities.
Buildings constructed in waterways and on unauthorised locations obstruct the natural flow of water, increasing the likelihood of flooding during heavy rains. Yet enforcement against these structures has been systematically weak. As John Osae-Kwapong of the Centre for Democratic Development noted in May 2025: 'There has to be some deficit in our urban planning and why we are seeing some of the things we continue to see — water appeared to have nowhere to go' (Asaase Radio, 30 May 2025).
The pattern of enforcement is starkly inequitable: bulldozers are quick to demolish the kiosks of the poor, but eerily silent when luxury estates encroach on floodplains. Construction permits have been issued in ecologically sensitive areas, and those with political and economic capital frequently receive preferential treatment when caught violating zoning regulations.
2.2 Cause Two: The Failure of Physical Planning
Ghana's physical planning framework, governed principally by the Land Use and Spatial Planning Act (LUSPA) 2016 and administered through the Land Use and Spatial Planning Authority (LUSPA), is structurally and operationally inadequate for the scale of urbanisation occurring in major Ghanaian cities. The core problems are institutional rather than legislative:
- Planning standards and regulations are routinely neglected in the development process — permits are frequently issued without compliance with environmental, drainage, or setback requirements.
- The processes involved in acquiring development permits are cumbersome and expensive, incentivising developers to proceed without permits entirely.
- Regulatory institutions and authorities are under-resourced, under-staffed, and subject to political interference that compromises their independence.
- 52% of households surveyed identified weak enforcement of land use regulations as the primary cause of flooding in their communities (peer-reviewed research cited in The Conversation, April 2025).
- Planning happens chaotically — no coordinated attention is given to ecological infrastructure, drainage corridors, wetland buffers, or catchment management in the development approval process.
The Enforcement Gap — A Documented Finding
Research published in The Conversation (April 2025), based on analysis of flood incidence data and interviews with regulatory agencies and residents, found that in 2017, there was a decrease in rainfall but an increase in flooding — conclusively demonstrating that precipitation is not the primary driver of Ghana's flood risk. Political interference in the enforcement of land use regulations was identified as the central mechanism sustaining the crisis.
2.3 Cause Three: Road Contracts Without Drainage
One of the most consequential and least discussed structural causes of Ghana's flooding is the systematic failure to include adequate drainage infrastructure in road construction contracts. This is not an occasional oversight — it is a documented pattern with direct, measurable consequences:
- The 2024 flooding of the Central Region that displaced 2,000+ people was directly linked to the diversion of the Ayensu River during highway expansion works on the Kasoa-Winneba road — a project without adequate accompanying drainage provision.
- Road construction that raises carriageway levels without corresponding drainage channels diverts stormwater onto adjacent properties and into communities, creating artificial flood risk where none previously existed.
- Contractors are frequently awarded road contracts where drainage specifications either do not exist, are inadequate for the catchment area's stormwater load, or are value-engineered out of the scope to reduce contract costs.
- The Ghana Highway Authority and the Department of Urban Roads lack mandatory, enforceable standards requiring drainage impact assessments before road contracts can proceed.
- Post-construction drainage maintenance is almost universally absent from contract specifications, meaning drainage structures that do exist rapidly become choked with sediment and solid waste and cease to function.
The GARID project has directly identified this problem in its scope of works. Drainage improvement works in Kaneshie include the construction of a storm drain from Accra Academy to Pramprom Junction and another from the Bank of Ghana Quarters to the Odaw — both remediation works addressing the consequences of road infrastructure built without adequate accompanying drainage.
2.4 Cause Four: Solid Waste and Drain Blockage
Ghana's urban drainage systems — where they exist — are chronically blocked by solid waste. Drains are choked not because of sudden cloudbursts but because solid waste mismanagement has made the drainage network dysfunctional. Plastic bottles, food waste, construction debris, and domestic refuse routinely block drainage channels, culverts, and bridge openings, converting manageable rainfall events into catastrophic flooding.
The Odaw River — Accra's primary drainage artery — has been periodically dredged but accumulates solid waste and sediment so rapidly that dredging operations require constant repetition. The GARID project's performance-based dredging of the Odaw Channel was reported as only 20% complete as of September 2024, despite the project having been operational since 2019. Broken sections of the Odaw channel at Achimota-Abofu are identified as a critical bottleneck that exacerbates flooding across a wide catchment area.
2.5 Cause Five: Climate Change as Amplifier, Not Originator
It would be inaccurate to entirely exclude climate change from a causal analysis of Ghana's flooding. The GARID project documentation notes that urban floods have become more frequent and of higher intensity due — in part — to climate-related changes in rainfall patterns. However, the peer-reviewed evidence is clear: climate change is an amplifier of an existing structural failure, not the originating cause. The same rainfall that fell on Accra in 1990 would have caused substantially less flooding than it does today, because in 1990 the wetlands were less encroached upon, the population was smaller, the built environment was less extensive, and the drainage system — such as it was — was less clogged with solid waste.
3. Property and Economic Impacts of Urban Flooding
Flooding is not merely a humanitarian crisis — it is a property crisis. It destroys capital, impairs collateral values, forces displacement, disrupts economic activity, and concentrates the burden of loss on the communities least able to recover from it.
3.1 Direct Property Destruction
Table 1: Selected Ghana Flood Events — Deaths, Displacement, and Property Damage
| Event | Deaths / Displaced | Direct Property Damage | Source |

| 1900–2021 total | 517 deaths; 5m+ affected | USD 615m estimated | MDPI Water, 2021 |
3.2 Collateral Value Impairment
For property lenders, investors, and valuers, flooding poses a specific and growing risk: the impairment of collateral values. A property that floods — or is in a zone with established flood risk — cannot be mortgaged at the same Loan-to-Value ratio as an equivalent property in a non-flood zone. The Bank of Ghana's prudential guidelines on LTV ratios do not currently include a mandatory flood risk discount, but lenders applying sound risk management must make this adjustment in their internal credit policies.
The implications for RICS-standard valuations are direct. A property adjacent to the Odaw River in Adabraka, or built on low-lying ground in Kaneshie, or within the Densu Delta flood plain, carries a materially different risk profile from an equivalent property on elevated ground with good drainage. This risk must be reflected in Market Value and, particularly, in Forced Sale Value (FSV) assessments. Properties that flood regularly will sell at deep discounts in a forced sale scenario — if they sell at all.
PDB Valuation Advisory Note
Property Databank advises all lenders, insurers, and investors to apply a flood risk assessment as a mandatory component of any RICS valuation commission in Ghana. Properties in identified flood-prone zones — including those adjacent to the Odaw, Densu, and other major drainage channels — should be assessed for: (a) flood frequency and depth based on available hydrology data; (b) access and egress reliability during flood events; (c) drainage adequacy of the plot and surrounding infrastructure; and (d) structural condition of drainage provisions on the property itself. FSV discounts of 20–40% relative to MV are appropriate for properties with confirmed, recurrent flood exposure.
3.3 Forced Displacement and the Housing Crisis
The immediate human consequence of flooding is forced displacement — families driven from their homes by inundation, structural failure, or both. In Ghana, this displacement disproportionately affects the urban poor: low-income communities built in flood-prone areas precisely because those were the only lands available to them, often without formal title, in informal settlements that lack the political visibility to command enforcement protection against the developers and infrastructure projects that worsen their flood exposure.
The 1.8 to 2 million unit housing deficit that Ghana already faces (Minister of Works and Housing, January 2026) is directly worsened by flooding events that destroy existing housing stock. The 2024 Central Region floods submerged over 200 homes. The 2015 Accra floods destroyed 187 homes and partially damaged hundreds more. Each destroyed home is a unit that must be replaced in a market already suffering acute undersupply — at costs that affected households, typically among the most economically vulnerable urban residents, cannot absorb.
3.4 Economic Disruption and Infrastructure Costs
Flooding disrupts economic activity far beyond the properties directly affected. Road impassability during flood events — a documented consequence of the May 2025 events in Kaneshie, Adabraka, Tema, and other areas — disrupts supply chains, prevents workers from reaching employment, closes markets, and imposes significant economic costs that extend across the affected city and its hinterland.
The direct cost to public infrastructure is also significant. The GH¢197 million allocated for controlling perennial floods in Accra in 2019 (approximately USD 38 million at then-prevailing rates), combined with the USD 200 million World Bank GARID project loan approved the same year and the subsequent USD 150 million in additional World Bank financing (approved May 2023; ratified by Parliament May 2024), represents a cumulative expenditure of USD 350 million in World Bank loan financing plus approximately USD 38 million in domestic government allocation — a combined total of approximately USD 388 million. All of this directed at a problem that competent physical planning and procurement discipline could substantially prevent. The failure is institutional, not financial.
4. Institutional Analysis: Why the System Fails
Ghana's flood crisis is not a policy gap — the legislative framework for physical planning and flood risk management is broadly adequate. It is an enforcement gap: a systematic failure of regulatory institutions to apply the laws, standards, and plans that exist, driven by political interference, resource constraints, and institutional fragmentation.
4.1 The GARID Project: A USD 350 Million World Bank Response to a Preventable Crisis
The Greater Accra Resilient and Integrated Development Project (GARID) is Ghana's largest urban resilience programme. Approved by the World Bank in 2019 with an initial envelope of USD 200 million — and expanded by USD 150 million in additional financing approved by the World Bank in May 2023 and ratified by Ghana's Parliament in May 2024 — GARID targets over 2.5 million residents of low-income, flood-prone areas in the Odaw River Basin. It is a direct response to the June 2015 twin disaster.
As of September 2024, the cumulative disbursement under GARID stands at USD 127.1 million, representing 36.3% of total credit. Nine major civil works projects are in progress, two are in final stages of contracting, and engineering designs for six additional projects are nearing completion. Dredging of the Odaw Channel is 20% complete. The project closing date has been extended from 2025 to December 31, 2027.
GARID is a necessary and broadly well-designed programme. But it is a remediation response to a crisis that competent physical planning should have prevented. The expenditure of USD 350 million in World Bank loan resources — to be repaid by Ghana's government over decades — to address flooding that is primarily caused by enforcement failures rather than by rainfall, represents an extraordinary cost of institutional dysfunction. Every cedi spent on GARID is a cedi that demonstrates the price of not enforcing planning regulations.
4.2 The Fragmentation of Regulatory Authority
Table 2: Regulatory Fragmentation in Ghana's Flood Risk Management System
| Institution | Formal Responsibility | Gap |
|---|---|---|
| LUSPA (Land Use & Spatial Planning Authority) | Development permits; land use planning; enforcement of zoning regulations | Under-resourced; politically compromised; no dedicated flood plain mapping capacity |
| Hydrological Services Department | Hydrological data; flood modelling; early warning systems | Data not systematically integrated into planning decisions or permit assessments |
| Ghana Highway Authority / Dept of Urban Roads | Road construction and maintenance | No mandatory drainage impact assessment requirement for road contracts |
| Environmental Protection Authority | Environmental impact assessments; wetland protection | Permits issued in ecologically sensitive areas; buffer zone violations tolerated |
| Metropolitan / Municipal Assemblies | Local planning approval; drainage maintenance; building inspections | Revenue-constrained; politically exposed; enforcement inconsistent |
| Ghana National Fire Service / NADMO | Flood response; emergency management | Reactive, not preventive; no enforcement mandate over development |
4.3 Political Interference and Elite Capture
Perhaps the most entrenched obstacle to flood risk management in Ghana is political interference in enforcement. The pattern is documented and consistent: regulatory institutions that move to demolish or restrain developments in flood-prone areas face political pressure — from elected officials, traditional leaders, or powerful private interests — to desist. The result is a two-tier enforcement regime in which the formal and informal poor are subject to demolitions while powerful actors build with relative impunity in waterways and floodplains.
This is not merely an observation by advocacy groups. It is a finding of peer-reviewed academic research: interview respondents noted that the siting of unauthorised buildings and encroachment on buffer zones of water bodies could have been averted, and they directly blamed political interference in the enforcement of land use regulation (The Conversation, April 2025; PreventionWeb, April 2025).
Until this political economy of planning enforcement is addressed, technical solutions — better drainage design, improved road contracting standards, GARID-funded infrastructure — will be repeatedly overwhelmed by the continued occupation of the waterways and floodplains on which they depend.
5. Policy Recommendations
Ghana has the legislative framework, the financial resources, and the development finance support to address its urban flood crisis. What it requires is political will, institutional discipline, and procurement reform. The following recommendations address the structural causes identified in this paper.
5.1 Physical Planning and Enforcement
- Establish a National Flood Plain Register — a publicly accessible, digitally maintained register of all identified flood plains, wetlands, drainage corridors, and buffer zones in Ghana's major urban areas, updated annually by the Hydrological Services Department and LUSPA. No development permit may be issued for land within a registered flood plain without a mandatory flood risk assessment conducted by an independent, RICS-qualified valuer or hydrological engineer.
- Mandate a 30-metre minimum buffer zone along all identified waterways, rivers, and drainage channels in urban areas, enforceable as a condition of any development permit, with demolition orders issued — and enforced without political exception — for all structures currently violating this buffer.
- Establish an Independent Planning Enforcement Inspectorate — a dedicated body separate from the Metropolitan Assemblies and LUSPA, reporting directly to Parliament, with powers to investigate, sanction, and if necessary prosecute violations of land use regulations, including by permit-granting officials who approve developments in breach of zoning standards.
- Implement a digital, georeferenced permit management system that records the precise location of every issued development permit relative to mapped flood plains, waterways, and drainage corridors — making spatial compliance auditable in real time.
5.2 Road and Infrastructure Procurement Reform
- Mandate Drainage Impact Assessments (DIAs) for all road contracts above GHS 500,000 in value, to be commissioned by the contract authority before tender and included as a mandatory tender requirement. No road contract may proceed to award without a certified DIA demonstrating that the proposed works will not increase stormwater runoff in adjacent communities beyond current baseline levels.
- Include drainage as a mandatory, non-value-engineerable component of every road contract, with minimum drainage capacity specifications set by the Ghana Highway Authority based on 25-year storm event modelling for each catchment area. Drainage works may not be reduced or omitted without parliamentary approval.
- Establish mandatory post-construction drainage maintenance contracts for all roads above GHS 1 million in value, requiring annual inspections and desilting to be funded from the original road contract budget. Payment of the final 10% of the contractor's fee should be contingent on satisfactory maintenance inspection at 24 months post-completion.
- Require that all road construction in urban areas coordinate with the relevant Metropolitan Assembly's drainage master plan — and that no road contract may proceed in areas identified as flood-prone without a drainage master plan existing.
5.3 Institutional Strengthening
- Adequately fund and staff LUSPA and the Hydrological Services Department at levels commensurate with the scale of urban development in Ghana's major cities. The current resource allocation is wholly inadequate for the volume of development being processed.
- Establish a joint inter-agency Flood Risk Management Committee with representatives from LUSPA, HSD, EPA, Ghana Highway Authority, NADMO, and the five major Metropolitan Assemblies, meeting quarterly, with a published action register and public reporting obligation.
- Adopt and promulgate mandatory flood risk disclosure requirements for all property transactions in identified flood-prone zones — including a standardised flood risk certificate, analogous to the energy performance certificates used in European jurisdictions, to be provided by the seller to the buyer before any sale agreement is executed.
5.4 Property Sector and Lending Recommendations
- The Bank of Ghana should issue a prudential guideline requiring all licensed lenders to apply a mandatory flood risk adjustment to property valuations used as collateral security, with LTV caps reduced by a minimum of 15 percentage points for properties in confirmed flood-prone zones.
- RICS Ghana and GhIS should jointly develop and publish a standardised methodology for flood risk assessment in property valuations, incorporating hydrological data from the Hydrological Services Department, to be applied as a mandatory component of all mortgage valuations.
- The Ghana Real Estate Agency Council should require all licensed estate agents to disclose to buyers any known flood risk affecting a property before any offer is made — and to be sanctioned for non-disclosure.
6. Conclusion
Ghana's urban flood crisis is a preventable catastrophe. The technical knowledge of what needs to be done is not in dispute. The legal authority to do it exists. The financing — from domestic resources and development partners — has been made available at extraordinary scale. What has been missing, consistently and at every level, is the institutional discipline and political will to enforce the rules, apply the standards, and resist the powerful interests that profit from building in the wrong places.
The flooding of May 2025 — four dead, more than three thousand displaced, an entire city brought to a standstill by 132 millimetres of rain — is not a climate emergency. It is the entirely predictable outcome of occupying waterways, blocking drainage, building roads without accompanying drainage infrastructure, and allowing the institutions charged with preventing exactly these outcomes to function without the resources, independence, or political support they require.
With heavier rains forecast and the rainy season far from over, the immediate priority is emergency response, evacuation, and shelter for those displaced. But the medium and long-term priority must be structural reform: a flood plain register, mandatory drainage impact assessments for road contracts, an independent enforcement inspectorate, adequate funding for LUSPA and the Hydrological Services Department, and mandatory flood risk disclosure in property transactions.
Ghana has committed approximately USD 388 million to flood remediation — USD 350 million in World Bank loan financing through the GARID project, plus an estimated USD 38 million in domestic government allocation for flood control. A fraction of that investment directed instead at prevention — at enforcing planning regulations, requiring drainage in road contracts, and adequately resourcing regulatory institutions — would yield far greater returns for the millions of Ghanaians whose homes, livelihoods, and lives are placed at risk every rainy season by institutional failures that are entirely within Ghana's power to correct.
"The government has the resources. A fraction of the resources committed to remediation could fund a generation of prevention. The choice is not technical — it is political."
