Sanwo-Olu warns Lagos residents against building on wetlands

Lagos State Governor Babajide Sanwo-Olu has cautioned residents and developers against constructing on wetlands and drainage channels, warning that such actions increase the state's susceptibility to flooding and coastal erosion. Speaking at the Nigerian Conservation Foundation's 20th annual Walk for Nature, Sanwo-Olu emphasized that the destruction of these vital ecosystems compromises public safety.

The governor highlighted the state's vulnerability due to its coastal location, low-lying terrain, and expanding population. He noted that wetlands, mangroves, and lagoons serve as the primary defense against flooding and coastal erosion. When these areas are filled or built upon, water accumulation leads to heightened risks. Sanwo-Olu's administration has taken steps to tackle environmental issues, including banning single-use plastics since July 2025 and collaborating with innovators to develop sustainable alternatives.

The governor also announced a suspension of reclamation activities on wetlands, floodplains, and lagoon fronts without proper environmental impact assessments and approvals. To bolster the state's natural defenses, the government is investing in drainage infrastructure, mangrove restoration, tree planting, and park development. Sanwo-Olu urged residents to prevent refuse from entering drains, avoid single-use plastics, and refrain from building on wetlands and drainage channels.

He encouraged young people to practice waste separation, tree planting, and promote environmental responsibility in their communities. The Nigerian Conservation Foundation's National Executive Council Chairman, Hon. Justice R.I.B. Adebiyi, highlighted Lagos's vulnerability to climate change, emphasizing the crucial role of wetlands, forests, waterways, and green spaces in maintaining the city's livability. She stressed that protecting nature is essential for safeguarding people against climate shocks.
