Stop Building On Hills Now Unchecked Construction Risks Environmental Disaster - Prof. Oteng-Ababio Warns

A senior urban planning expert, Professor Martin Oteng-Ababio, has issued a stark warning regarding the proliferation of unplanned and uncontrolled residential development on hilltops across Ghana. He cautions that such unchecked construction, coupled with the indiscriminate clearing of vegetation, is rapidly creating conditions for severe environmental disasters, including mudflows, landslides, and exacerbated flooding. Despite a robust legal framework governing spatial planning, building standards, and environmental protection, the core challenge lies in the consistent enforcement of these laws by relevant authorities. This article examines Ghana's comprehensive legal and regulatory landscape pertaining to urban development and environmental safeguards, highlighting the critical gaps in implementation that expose communities to grave risks and necessitate urgent, decisive action from policymakers and enforcement agencies.

Ghana's rapid urbanisation has brought with it significant developmental challenges, none more pressing than the unchecked expansion of human settlements into ecologically sensitive areas. Professor Martin Oteng-Ababio, a prominent urban planning expert, recently sounded an alarm, urging the government to impose an immediate ban on unplanned residential development on hilltops. His warning underscores a critical vulnerability: the country is 'sitting on a time bomb waiting to detonate soon,' as indiscriminate clearing of vegetation on hills for housing exposes communities to devastating mudflows, landslides, and severe erosion, particularly with intensifying rainfall.

This alarming prognosis highlights a disconnect between Ghana's progressive legal framework for land use and spatial planning and its practical implementation. While a comprehensive set of laws and regulations exists to guide sustainable development and protect the environment, the persistent issue of illegal and unregulated construction on vulnerable terrain suggests significant enforcement deficits. This article delves into the relevant Ghanaian statutes and regulatory instruments, analysing their provisions concerning construction in environmentally sensitive areas and identifying the systemic challenges that contribute to the current precarious situation, ultimately posing severe risks to lives, property, and the environment.

The legal and regulatory landscape governing land use, spatial planning, and construction in Ghana is multifaceted, designed to promote orderly development and environmental protection. Central to this framework is the **Land Use and Spatial Planning Act, 2016 (Act 925)**, which repealed and replaced the older Town and Country Planning Act. This Act established the Land Use and Spatial Planning Authority (LUSPA) as the primary regulatory body for spatial planning and management of settlements, tasked with ensuring sustainable land development, judicious use of land, and a decentralised planning system. Complementing Act 925 are the **Land Use and Spatial Planning Regulations, 2019 (L.I. 2384)**, which provide detailed guidelines for preparing and implementing zoning plans.

At the local level, the **Local Governance Act, 2016 (Act 936)** designates Metropolitan, Municipal, and District Assemblies (MMDAs) as the planning authorities for their respective jurisdictions. These assemblies are empowered to approve development plans, issue permits for physical development, and crucially, to prohibit, abate, alter, remove, or demolish any physical development that does not conform to an approved district development plan. Further buttressing these planning controls are the **National Building Regulations, 1996 (L.I. 1630)**, which set minimum standards for building design, construction, and safety, and the more recent **Ghana Building Code, 2018 (GS 1207:2018)**, a comprehensive document based on the International Building Code, stipulating requirements for structural safety, setbacks, and mandatory permits. Environmental considerations are addressed by the **Environmental Protection Act, 2025 (Act 1124)**, which replaced the **Environmental Protection Agency Act, 1994 (Act 490)**, establishing the Environmental Protection Authority (EPA) with expanded regulatory powers to manage, coordinate, and protect the environment, including mandating Environmental Impact Assessments (EIAs) for certain development projects under the **Environmental Assessment Regulations, 1999 (L.I. 1652)**.

Despite the seemingly robust legislative framework, the persistent issue of uncontrolled hilltop construction points to significant challenges in its application and enforcement. Professor Oteng-Ababio's warning highlights that many hills, including the Aburi, Bortianor, and McCarthy ranges, are being developed without proper planning, often in areas ecologically sensitive or even within or near earthquake fault zones. The legal instruments, such as the Land Use and Spatial Planning Act, 2016 (Act 925), clearly mandate that no physical development shall be carried out without prior written approval from the District Planning Authority. Furthermore, the Ghana Building Code, 2018 (GS 1207:2018), sets minimum requirements for structural safety and setbacks, which are critical for construction on challenging terrains.

The primary impediment appears to be weak enforcement. Investigations into numerous building collapses in Ghana have consistently revealed a pattern of illegal construction, often lacking approved building plans, development permits, and a disregard for stop-work orders. MMDAs, which are legally responsible for approving developments and enforcing building regulations, frequently lack the necessary resources, including sufficient building inspectors, vehicles, and testing equipment. This logistical deficit often results in irregular or superficial inspections, failing to detect critical structural defects or non-compliance with environmental safeguards.

Moreover, the problem is compounded by factors such as corruption, bureaucratic delays, and political interference, which undermine the integrity of the planning and permitting processes. While the Environmental Protection Authority (EPA) is mandated to ensure compliance with environmental assessment procedures for development projects, its historical focus on large-scale contracts may have inadvertently left smaller, yet cumulatively impactful, environmental infractions unaddressed. The Land Use and Spatial Planning Authority (LUSPA), despite its national mandate, reportedly lacks direct enforcement or sanctioning powers over district assemblies, only being able to recommend action to the Minister, which can create a bureaucratic bottleneck and dilute accountability.

The consequences of these enforcement gaps are dire. The indiscriminate clearing of vegetation on hillsides, a direct result of uncontrolled development, leads to severe soil erosion and increases the risk of mudflows and landslides, particularly during heavy rainfall. This not only threatens the safety of residents but also exacerbates perennial flooding in urban centres, as wetlands that naturally absorb runoff are also being reclaimed for development, leaving floodwaters with limited drainage pathways. The **Ghana Hydrological Authority Act, 2022 (Act 1085)**, which establishes an authority for flood control, underscores the government's recognition of this problem, yet its effectiveness is contingent on robust spatial planning and building regulation enforcement.

Comparative analysis with jurisdictions that successfully manage construction on hilly terrain reveals that such development is permitted only under meticulously designed and strictly enforced planning frameworks. Professor Oteng-Ababio points out that research indicates a significant portion of Accra's hilly landscapes are unsuitable for residential development, yet construction persists. This highlights a critical need for MMDAs to not only possess the legal authority but also the political will, resources, and institutional capacity to enforce existing laws rigorously, including the **Building Regulations, 2022 (L.I. 2465)**, which explicitly aim to ensure safety, public health, and environmental protection in construction.

The urgent warning from Professor Martin Oteng-Ababio serves as a critical reminder that Ghana's impressive legal architecture for urban planning and environmental protection is only as effective as its enforcement. The unchecked development on hilltops, driven by a combination of weak oversight, resource constraints at the local government level, and potentially corrupt practices, poses an existential threat to communities through environmental disasters like landslides and exacerbated flooding. The existing statutes, including the Land Use and Spatial Planning Act, 2016 (Act 925), the Local Governance Act, 2016 (Act 936), the Ghana Building Code, 2018 (GS 1207:2018), and the Environmental Protection Act, 2025 (Act 1124), provide ample legal grounds to address these challenges.

For legal practitioners, this situation presents both a challenge and an opportunity. Attorneys advising developers must conduct rigorous due diligence to ensure full compliance with all planning, building, and environmental permits, mitigating significant legal and financial risks, including potential demolition orders and criminal sanctions. Conversely, legal professionals can play a vital role in advocating for stronger enforcement, representing communities affected by illegal construction, and pushing for accountability against officials who fail to uphold their statutory duties. Moving forward, a concerted effort is required from all stakeholders—government, regulatory bodies, developers, and citizens—to translate 'paper laws' into 'safe homes' and sustainable development. Policymakers must focus on empowering and resourcing MMDAs, streamlining inter-agency coordination, and implementing robust anti-corruption measures to safeguard Ghana's environment and its citizens from preventable disasters. The continued monitoring of legislative reforms, particularly those aimed at strengthening enforcement mechanisms and institutional capacities, will be crucial in determining whether Ghana can avert the looming environmental catastrophe.
