Coastal cities in Africa face increasing threats from rising sea levels, which are largely driven by the climate crisis caused by the Global North’s obsession with fossil fuels. As these cities grapple with potential displacement of millions and considerable economic loss, the impacts of this crisis become more evident.
The climate crisis would wipe away Lagos
Rising sea levels are not just a distant threat; they are a looming reality for many coastal communities in Africa.
Urban areas are particularly at risk due to factors such as rapid urbanisation, weak infrastructure, and an increase in climate crisis-related disasters like flooding. This alarming situation draws attention to the urgent need for global action as scientists warn that if current temperatures continue to rise, extensive land could be submerged, leading to the loss of entire communities.
Lagos, Nigeria, is one of the most pressing examples of this crisis.
This vital economic hub is experiencing significant challenges as the Atlantic Ocean encroaches upon its low-lying coastline. The situation is deteriorating rapidly; a study from the University of Plymouth highlights that a sea level rise of three to nine feet could lead to devastating consequences for human activities, potentially displacing populations and severely damaging critical infrastructure.
Alexandria, Egypt, another historic coastal city, faces similar threats.
Known for its rich history and founded by Alexander the Great, Alexandria is witnessing a gradual disappearance of its beaches. The United Nations Climate Panel (IPCC) has projected that by 2050, sea levels could rise by one metre, which would inundate one-third of the fertile land in the Nile Delta and result in the flooding of cities like Alexandria.
The city already sinks by an average of three millimetres annually, a situation worsened by upstream dams on the Nile that prevent the natural deposition of silt and offshore gas drilling activities. Projections suggest that by 2100, the Mediterranean could rise by as much as two feet, placing Alexandria and other coastal areas at heightened risk of catastrophic flooding.
The Global North once again destroying the Motherland
Adaptation strategies are being explored, such as the construction of seawalls, enhancing drainage systems, and restoring mangroves. However, these measures may not be sufficient without significant global efforts to reduce emissions from the countries of the Global North, which have historically contributed significantly to climate change.
Without urgent international cooperation and a commitment to climate resilience, Africa’s coastal cities are set to face drastic transformations by the end of the century, potentially leading to the loss of some of their most vibrant urban centres to the sea.
