• More than 60% of Harare's wetlands have reportedly been degraded or destroyed, according to figures cited in a February 2026 parliamentary wetlands advocacy document
• Government halted development activity at Monavale Wetland in May 2026 following concerns over land clearing at the internationally protected site
• Wetland destruction threatens to increase flooding, water-management costs and infrastructure expenditure, weakening Harare's long-term economic resilience

Harare – Harare's continued destruction of wetlands is exposing a growing economic contradiction, as urban development creates immediate commercial opportunities while eroding natural infrastructure that protects properties, regulates water systems and reduces municipal expenditure. With more than 60% of the capital's wetlands reportedly degraded or destroyed, the city faces the prospect of rising infrastructure costs and greater financial exposure for businesses and households.

A February 2026 parliamentary wetlands advocacy document attributed the degradation to urban development, illegal settlements and sand extraction. Although the reported figure requires independent verification against the underlying environmental mapping, it points to substantial pressure on ecosystems that support Harare's water security. Wetlands retain rainfall, regulate surface runoff and contribute to natural water filtration, providing services that would otherwise require more extensive engineered infrastructure.

The economic consequences become apparent when these functions deteriorate. Land conversion can generate revenue through property sales, construction and municipal charges, but the resulting loss of water-retention capacity may increase flooding, damage infrastructure and create additional financial obligations for local authorities. Development gains can therefore be concentrated among property investors while some environmental costs are transferred to surrounding communities.

The dispute at Monavale Wetland illustrates this conflict. In May 2026, residents and environmental campaigners protested against land clearing and grading activities at the Ramsar-listed site, raising concerns about proposed residential development on environmentally sensitive land. Government subsequently ordered the activities to stop, with Permanent Secretary for Presidential Affairs and Devolution Tafadzwa Muguti stating that the development lacked the necessary Government or parliamentary clearance.

Monavale covers approximately 507 hectares and forms part of the wider Manyame catchment, which supports water resources serving Harare and surrounding settlements. Its vegetation and soils contribute to groundwater processes, natural drainage and biodiversity conservation, making the wetland important beyond the boundaries of the disputed development site.

The Government's intervention brought renewed attention to the economic implications of land-use decisions. Removing wetland vegetation or altering natural drainage patterns can accelerate runoff into surrounding areas, increasing the pressure on stormwater infrastructure during heavy rainfall. Where drainage systems are inadequate, the consequences can include damaged roads, flooded properties and interrupted commercial activity.

These risks carry direct costs for households and businesses. Property owners may require additional drainage works, repairs and flood protection, while businesses can lose revenue through damaged inventory, disrupted transport and temporary closures. Public authorities may face increased expenditure on infrastructure rehabilitation, diverting resources from other essential services.

Water quality presents a related challenge. Wetlands contribute to natural filtration and catchment stability, although their precise impact on treatment costs varies according to local hydrological conditions and pollution levels. Their degradation can weaken these ecological services at a time when Harare already faces substantial problems involving wastewater management and contamination within the Lake Chivero catchment.

Wetland destruction should not be treated as the sole cause of the capital's water difficulties. Ageing sewerage infrastructure, industrial discharges and inadequate pollution control remain major contributors. However, degrading natural filtration and drainage systems adds pressure to an already constrained urban water network, increasing the importance of coordinated catchment management.

The implications also extend to Harare's property market. Demand for residential and commercial land has supported construction activity, employment and investment, but development on environmentally sensitive sites can expose buyers to risks that are not fully reflected in purchase prices.

Properties affected by persistent flooding may require more expensive foundations, drainage systems and maintenance. Financial institutions and insurers also face potential exposure where environmental risks weaken property values or increase the cost of protecting financed assets.

Consequently, the economic value of a development cannot be assessed solely through land sales and construction expenditure. A comprehensive evaluation must account for the infrastructure costs, environmental liabilities and long-term risks created by altering natural water systems.

Zimbabwe's Environmental Management Act provides mechanisms for protecting wetlands and regulating activities that may disturb their ecological functions. Section 113 establishes restrictions on specified wetland activities without the required environmental authorisation, while the National Wetlands Policy provides a broader framework for conservation and sustainable management.

The challenge lies in enforcement and coordination. Land-use decisions involve local authorities, environmental regulators and institutions responsible for managing water resources, creating a need for clear approval procedures and consistent monitoring.

Environmental assessments should establish the ecological status of proposed development sites and examine the effects on drainage, groundwater, biodiversity and neighbouring properties. They must also consider cumulative impacts, as multiple developments within the same catchment can collectively weaken water-retention capacity even when individual projects appear manageable.

Transparent development approvals and publicly accessible environmental assessments would strengthen accountability while reducing uncertainty for property investors. Such measures would also allow affected residents to understand the environmental implications of proposed projects before construction begins.

The Monavale intervention demonstrates the value of regulatory action before extensive damage occurs. Restoring degraded wetlands can require substantial investment in vegetation rehabilitation, drainage correction and environmental monitoring, with no guarantee that the original ecological functions can be fully recovered.

Protecting existing wetlands may therefore be more economically efficient than financing restoration after development. Conservation can also support urban liveability, biodiversity and recreational spaces, improving the environmental conditions that make cities attractive to residents and investors.

Harare's development challenge is not a choice between economic expansion and environmental protection. The objective should be to direct construction towards suitable land while preserving natural systems that reduce infrastructure pressure and protect public resources.

As the capital expands, the financial consequences of environmental degradation will increasingly depend on the quality of planning decisions and the effectiveness of regulatory enforcement. Continued wetland conversion risks creating short-term property gains alongside persistent municipal costs, greater flood exposure and declining water security.
