World Bank Backs Coastal Defense and Jobs in West Africa With $240 Million Plan

Benin and Mauritania

Along the low-lying coasts of West Africa, where fishing villages meet expanding port cities, the ocean has long been both a source of life and a growing threat. Each year, tides creep further inland, swallowing farmland, eroding homes and displacing communities that have lived along the shoreline for generations.

In response to these mounting pressures, the World Bank has approved $240 million in financing to strengthen coastal resilience while unlocking new economic opportunities tied to the sea. The funding marks the first phase of an expanded regional initiative known as the West Africa Coastal Areas Resilience and Blue Economy Program (WACA+), a project that seeks to address climate vulnerability and economic development in tandem.

The initial investments will focus on Benin and Mauritania, two countries where coastal degradation has become both an environmental and economic concern. In Benin, the program will target the Bouche du Roy estuary and the Mono River delta, critical zones for agriculture, fisheries and transport that have been increasingly affected by erosion and flooding. In Mauritania, efforts will center on reinforcing the fragile dune barrier that protects Nouakchott, the capital, where rising sea levels pose a direct threat to infrastructure and urban life.

Across the region, the urgency is clear. More than 360 million people in West Africa live in coastal areas, many of them dependent on industries such as fishing, tourism and maritime trade. These sectors, which collectively support millions of jobs, are increasingly vulnerable to changing weather patterns, declining fish stocks and the steady advance of the sea.

The World Bank’s approach reflects a broader shift in development thinking, one that seeks to integrate environmental protection with economic growth. Rather than focusing solely on physical infrastructure such as seawalls and barriers, the WACA+ program also prioritizes ecosystem restoration. Plans include the rehabilitation of thousands of hectares of mangroves and coastal wetlands, which act as natural buffers against storm surges while supporting biodiversity and sustaining local fisheries.

Such nature-based solutions, long overlooked in large-scale infrastructure planning, are gaining traction as cost-effective and sustainable alternatives. Mangroves, for instance, not only absorb wave energy but also serve as breeding grounds for fish, helping to secure food supplies and livelihoods for coastal communities.

At the same time, the initiative places a strong emphasis on job creation through what policymakers describe as the “blue economy”, a broad category that includes fisheries, aquaculture, coastal tourism and marine services. By investing in these sectors, officials hope to create more stable and higher-value employment opportunities, particularly for young people and women, who often face limited prospects in traditional coastal economies.

Early projections suggest that the program’s first phase could generate around 13,000 jobs. But beyond the numbers, the aim is to foster industries that are more resilient to climate shocks, reducing the vulnerability that has long defined coastal livelihoods.

The initiative also underscores the importance of regional cooperation. Coastal erosion is not confined by national borders, and sediment flows, currents and weather systems connect countries along the Gulf of Guinea and the Atlantic coastline. As a result, the program encourages governments to align policies, share data and coordinate interventions, a departure from the fragmented approaches that have historically limited the effectiveness of such efforts.

Still, the path ahead is far from straightforward. Large-scale coastal projects are inherently complex, requiring not only significant financial investment but also technical expertise and long-term maintenance. Past initiatives in the region have struggled with delays, funding gaps and governance challenges, raising questions about whether the current effort can deliver sustained results.

There are also broader concerns about balancing development with environmental preservation. While the expansion of blue economy industries offers economic promise, it must be carefully managed to avoid overexploitation of marine resources, a risk that has undermined similar efforts elsewhere.

For now, the World Bank’s investment represents a renewed attempt to confront one of the region’s most pressing challenges with a more integrated strategy. By linking climate resilience with economic opportunity, the program seeks to move beyond short-term fixes toward a longer-term vision of sustainable coastal development.

Whether that vision can be fully realized will depend not only on funding and execution, but also on the ability of governments, communities and institutions to work together in navigating an increasingly uncertain environmental future.
