Ghana, facing the Gulf of Guinea, has a coastline stretching for more than 500 kilometers. Historically, this coastal belt has been the country’s economic and cultural heart, hosting key cities such as Accra and Tema, major commercial ports, and centuries-old fishing communities. Today, however, the complex interaction between these densely populated areas and the ocean makes the country a true open-air laboratory—both essential and vulnerable—for studying sea-level rise and coastal erosion.
The shoreline is characterized by an alternation of sandy beaches, fragile lagoon ecosystems, and river mouths, where roughly a quarter of the national population lives. Much of the infrastructure and housing lies just above mean sea level, in areas of extremely high exposure. Over the past decades, the ocean has devoured large stretches of land: in some critical areas, the coastline has retreated by more than two meters per year. These figures, combined with global projections related to climate change, foreshadow increasingly destructive impacts on local economies and ecosystems.
The experience of communities such as Keta and Fuveme, located in the Volta River delta region, reveals the deep drama of this crisis: violent storm surges and erosion have gradually swallowed entire sections of villages, destroying homes and schools and forcing hundreds of families to abandon their land. As ocean currents continue to shift and storms intensify, such devastation threatens to become the norm, putting at risk not only modern settlements but also the centuries-old coastal colonial forts—UNESCO World Heritage sites—that now face the danger of collapsing into the sea.
To counter these risks, the government and international organizations are implementing major engineering works, such as the Keta Sea Defence Project, alongside nature-based solutions including the restoration of mangrove forests to reduce the force of incoming waves. The challenge for Ghana—a nation whose identity, history, and prosperity are inseparably tied to its coasts—will be to develop long-term adaptation strategies capable not only of protecting its people but also of providing a crucial case study for coastal resilience on a global scale.
