Nigeria’s coastal belt, stretching from Lagos to Bayelsa, is home to millions of people who depend on fishing, farming and trade for survival. These coastal communities over the years, have added their own quota to the economy of the country.
Today, these once-thriving communities face a grave threat: rising sea levels and increasingly destructive coastal storms that are eroding land, flooding homes, destroying habitats and pushing entire settlements closer to extinction.
According to climate experts, Nigeria loses significant stretches of land each year to the Atlantic Ocean. Communities in states such as Lagos, Delta, Bayelsa, and Rivers are particularly vulnerable.
Beyond gradual sea encroachment, coastal storms are becoming fiercer and more frequent. Heavy rains combined with storm surges wash away farmland and destroy infrastructure. These storms not only cause immediate destruction but also worsen erosion, leaving communities more vulnerable with each season.
The impact goes beyond physical displacement. Families are losing ancestral lands and cultural heritage tied to their environment.
Beaches, where children once played, are being eaten away by erosion. Eighty percent of the shoreline in Lagos State has been lost, according to a report. Apakin, a coastal community in Lagos State, was once famous for its vast number of coconut trees.
According to the community head, Abimbola Iyowun, the last 50 metres of coconut trees disappeared four years ago. This has affected the production of coconut oil used in the cosmetic industry. Rachael Tonde is in the coconut oil business. “I produce coconut oil locally, and I also supply coconuts to factories. We hardly get coconuts to supply, and this has affected business,” she stated.
In June 2025, a coastal flood swept through the Apakin community, further sweeping away houses, graves, and means of livelihood of the inhabitants.
Itak Abasi, a fishing community in Akwa Ibom State was obliterated in 2011 when the shoreline shifted by 600 metres. In the Niger Delta, shoreline retreat forced the Opobo/Nkoro community to be relocated.
Aiyetoro, a community in Ilaje LGA of Ondo State, also suffered chronic shoreline retreat. The recurrent erosion washed away homes, schools, and churches, causing loss of livelihood and displacement of residents. Today, what was once a vibrant fishing community has been reduced to fragments of land.
The story is the same for communities like Twon-brass and Okpoama in Bayelsa State.
These communities, forced to migrate inland, often struggle to integrate. They face overcrowding, land disputes, and loss of traditional livelihoods. Rising salinity in groundwater also contaminates drinking water and reduces crop yields, deepening food insecurity.
The rise in sea level is largely fueled by global warming which melts polar ice caps and expands sea water volumes. For low-lying coastal areas even a few centimeters of sea level rise can mean catastrophic flooding. In addition, mangroves, which are natural buffers against waves, are dying due to saltwater intrusion and are being reduced due to deforestation.
Construction of mega infrastructures such as oil installations has also been cited by environmentalists as causing increased erosion in these communities and shoreline destabilization.
Indigenous dwellers of some of these communities expressed displeasure concerning the discrepancy in protection against disaster. “It is painful that infrastructures are protected but not the communities,” stated a local.
In Finima on Bonny Island, oil infrastructure is shielded behind costly defenses while nearby villages are left exposed to the waves.
Environmental experts say Nigeria needs a coordinated, multilayered strategy to combat the situation. According to a report published in the Nigerian Journal of Environmental Sciences and Technology, the strategy should include climate mitigation, continuous shoreline monitoring, enforcing no-build zones in high-risk areas, construction of eco-friendly defenses, and enhancement of community resilience through early warning systems. In addition, there should be socioeconomic support for the relocation of communities.
Loss of coastal communities in Nigeria is not just an environmental issue; it is a human one. The locals are not statistics; they are farmers, fishermen, and traders who have lived by the sea for generations.
Without urgent action taken, Nigeria runs the risk of erasure of communities that once thrived along its shore.
