The Lagos State Government, through the Lagos State Commissioner for Waterfront Infrastructure Development, Ekundayo Alebiosu, has unveiled plans to invest N3tn in groyne technology to safeguard the state’s coastline from erosion.
Speaking at the ministerial press briefing to mark the second year of the second term of Governor Babajide Sanwo-Olu in office, the commissioner disclosed that part of the efforts was his strategic working visit to the Kingdom of the Netherlands, where he led a high-level delegation, including the Permanent Secretary, Lolade Aina, to explore international best practices and forge partnerships for sustainable coastal management.
According to Alebiosu, a groyne is a rigid hydraulic structure built from an ocean shore or riverbank that interrupts water flow and limits the movement of sediment.
He continued, “The technology has been effectively used to arrest coastal erosion and stabilise beaches in several parts of the world, including the Netherlands.”
Though Lagos State has already begun implementing this technology, the sheer scale of the challenge to stretch the usage along the 180km stretch of shoreline presents a significant financial burden.
“It costs a huge amount to construct a single groyne, and with a targeted 180km coastal stretch, the projected cost exceeds N3tn, a figure that makes it clear that strategic collaboration is required.
“This is not just a Lagos problem, it is a national environmental and economic challenge. If we are serious about preserving our shoreline, preventing further erosion, and protecting coastal communities, then a robust partnership with the Federal Government and the private sector is not just desirable, it is absolutely necessary,” Alebiosu said.
The commissioner described the Netherlands, renowned for its pioneering coastal engineering solutions, as a perfect case study for the state government delegation.
“The Dutch model, which integrates groynes, sand nourishment, and nature-based solutions, provided insights into how sustainable and economically viable approaches can be adapted to suit local conditions in Lagos,” he added.
He asserted that the Lagos State Government was actively pursuing a Public-Private Partnership framework to finance and implement large-scale groyne deployment and coastal protection infrastructure.
“This initiative also aligns with Governor Babajide Sanwo-Olu’s administration’s broader agenda to secure lives, protect public and private assets, and unlock the economic potential of Lagos’ vast waterfronts.
“We cannot afford to delay. Entire communities are at risk, and if left unchecked, the consequences of coastal erosion could be devastating, not only to the environment but also to livelihoods and investments across our coastal zones,” he stated.
