Drains, Morass and Homes: The Flood Programme Protecting St Elizabeth’s Communities

Kingston, Jamaica, 7 September 2023

Thirty-four communities across St Elizabeth are benefiting from a drainage programme managed by the National Irrigation Commission that maintains the upper and lower morass of the Black River, a waterway and wetland system whose management directly determines the flood exposure of thousands of homes and landholdings across the parish. The programme, which combines mechanical and manual drain-clearing methods across approximately 237 kilometres of canals and drains, spans an area of more than 10,000 hectares and serves communities from Siloah in the north to Santa Cruz in the east and Black River in the west.

The National Irrigation Commission’s mandate over the Black River system is grounded in law. Under Section 4 of the Irrigation Act, the commission is required to drain specific sections of the Black River, and the upper and lower morass represent the central drainage challenge in the parish. In 2022 the commission added an amphibious excavator to its equipment fleet, acquired at a cost of approximately $78 million, which has allowed it to clean an average of 10 kilometres of drains per month across terrain that conventional land-based machinery cannot access.

Flood Mitigation as a Housing Issue

The connection between drain maintenance and housing security in St Elizabeth is direct and well-established. Communities adjacent to the morass and its tributary systems have a documented history of flooding during heavy rainfall events, with residents periodically forced from their homes and farmers losing crops and infrastructure to rising water. The 1979 flood, which swallowed the community of New Market and led the government to develop the adjacent settlement of Lewisville as a relocation community, remains a reference point in community memory. More recently, Tropical Storm Nicole in 2010 displaced residents across a broad area of the upper morass communities.

For families whose homes are built on or near flood-prone land, the maintenance of drainage infrastructure is not an agricultural service but a direct determinant of housing security. A home that floods repeatedly is a home that depreciates, that becomes uninsurable, that is difficult to sell and that cannot serve as the foundation of wealth accumulation that property ownership is supposed to represent. The NIC’s drainage programme, though framed primarily in terms of agricultural protection and land reclamation, is performing a critical function in sustaining the habitability and property values of dozens of communities across the parish.

The Tourism and Economic Link

The NIC’s director for engineering and technical services has noted that drainage activities allow for the reclaiming of land for agricultural activities and the clearing of waterways that add value to recreation and tourism businesses. That observation points to an underappreciated dimension of the morass management question: the Black River and its wetland system are, when well managed, an economic asset. The Lower Morass supports the Black River Safari tours, which are among the most distinctive tourism offerings in the parish and a key draw for visitors to Black River town. The health of the river system, its water quality, its wildlife and its navigability, is therefore directly linked to the commercial viability of businesses that depend on tourist access.

A System Under Pressure

The NIC’s programme is meaningful, but it operates within a context of growing pressure on the morass system. The Upper Morass has been progressively compromised by encroachment over half a century, and climate change is increasing the frequency and intensity of rainfall events that test the drainage system’s capacity. The maintenance programme buys time and reduces exposure, but it does not resolve the underlying dynamic between settlement patterns and flood risk in this part of St Elizabeth. That dynamic will require a more comprehensive policy response, one that addresses land use, housing location and community resilience together rather than managing the drainage system in isolation. The lessons of 2025 would make that reality impossible to avoid any longer.
