Illegal dredging worsening pressure on housing – LASG

Lagos State Government has intensified warnings about illegal dredging operations undermining the state's waterway infrastructure and exacerbating an acute housing shortage. The LASG has completed over 50 kilometres of channelisation works across major ferry routes, attempting to restore navigability while combating unregulated sand extraction that threatens both transportation networks and residential land availability.

Illegal dredging in Lagos lagoons and waterways has accelerated pressure on the city's already constrained housing market. Uncontrolled sand mining removes critical sediment that stabilises wetlands and floodplain zones—areas increasingly targeted for residential development. As illegal operators extract sand for construction materials, they destabilise these marginal lands, making them unsuitable for housing projects and driving developers toward prime real estate, inflating property prices across the state.

## Why Is Illegal Dredging Destroying Lagos Waterways?

Unregulated dredging operations lack environmental oversight and proper disposal protocols. Criminal networks extract sand, gravel, and aggregate from lagoons and channels without permits, leaving behind eroded banks, deepened channels that alter water flow, and contaminated sediment that clogs navigation routes. The Lekki-Epe Expressway, Third Mainland Bridge approaches, and Badagry Creek corridors have all experienced navigation hazards due to accumulated silt from illegal dredging sites upstream. These operations bypass revenue systems, costing Lagos ₦billions in lost royalties annually.

## How Does Waterway Degradation Link to Housing Supply Crisis?

Lagos's housing deficit—estimated at 2 million units—stems partly from constrained developable land. Illegal dredging reduces the available land bank by destabilising wetland areas that could otherwise support low-to-medium density housing. When waterway infrastructure fails, flood risk increases, making adjacent areas uninsurable and unmarketable. This forces developers to concentrate projects in already-saturated zones (Victoria Island, Ikoyi, Lekki), driving land costs to ₦150M–₦500M per hectare—pricing out middle-income buyers and worsening the affordability crisis.

LASG's 50km channelisation programme targets Lagos Lagoon, Badagry Creek, and Ijora Causeway approaches. These works restore ferry routes, reduce flooding during high tides, and attempt to reclaim land lost to erosion. However, enforcement against illegal operators remains inconsistent. Without simultaneous crackdowns on permit violations and criminal networks, dredging pressure will continue.

## What Are the Investment Implications?

Real estate investors should note escalating environmental and regulatory risks. Projects in flood-prone or wetland-adjacent zones face higher insurance costs, extended permitting delays, and future climate liability. Conversely, infrastructure plays—maritime transport operators, dredging contractors with legitimate LASG contracts, and flood-control engineering firms—may see revenue uplift as the state scales waterway restoration.

Property developers should prioritise sites with certified drainage and flood-resilience infrastructure. Waterfront properties in stabilised zones (Lekki Phase 1, Victoria Island) retain premium valuations, while speculative bets on newly-opened wetland areas carry execution risk. The housing shortage remains structural; channelisation alone won't solve it. Supply-side interventions—land release, zoning reforms, transport-oriented development—are necessary.
