Pacific Island cities are engines of economic opportunity, generating between 50 and 70 percent of national income. But they are also among the most hazard-exposed urban areas on the planet: one storm, flood, or coastal surge can close ports, block roads, or shut down businesses. When that happens, jobs disappear — sometimes permanently.
With Pacific urban centers projected to host nearly half of the region’s population by 2050, understanding the risks they face is essential. Drawing on the Livable Pacific Cities and Towns Spotlight: Tides of Change – Urban Resilience Across Pacific Landscapes report, this blog explains how World Bank Group diagnostics can help Pacific Island governments better understand their hazard exposure and make smarter decisions for jobs and growth.
Rising Risk, Rising Stakes
A recent World Bank Group study of 38 urban areas across 10 Pacific Island countries found that the number of people exposed to major hazards could more than double by 2050. The value of at-risk building assets is expected to grow from $33 billion to more than $58 billion for cyclone and earthquake hazards alone. With urban populations in the region projected to double in just 25 years, the economic stakes are rising fast.
When these assets are disrupted, the effects ripple outwards quickly. Supply chains slow, tourism declines, businesses close, and workers lose income. For small island economies with limited fiscal buffers and few alternative employment options, the damage can be lasting. Understanding exactly where these risks lie is therefore central for job creation and economic growth in the Pacific.
From Analysis to Action: Three Cities, Three Approaches
The World Bank Group has been piloting a set of practical diagnostic tools to help Pacific cities map their risks and translate that knowledge into smarter decisions. Three recent examples illustrate what this looks like in practice.
1. Kolonia, Federated States of Micronesia 🇫🇲
Using satellite imagery and global data, analysts produced a “rapid city scan” of how the city functions and where it is most exposed. Much of Kolonia’s economic activity is concentrated in areas increasingly exposed to coastal flooding, sea-level rise, and typhoons. Key roads connecting the town and the nation's capital are at risk of disruption. The analysis also identified opportunities: high urban density, strong vegetation coverage, and solar energy potential. These insights can help policymakers direct investment to where it will be most effective, and most durable.

2. Majuro, Republic of the Marshall Islands 🇲🇭
Majuro stretches across a narrow atoll, concentrating communities, businesses, and public services on a thin strip of land between the ocean and lagoon. A “critical hazard assessment” identified the neighborhoods most exposed to flooding, highlighting where drainage, coastal protection, and resilient housing investments are most urgently needed. As more people migrate from outer islands to Majuro, having a clear map of risk is essential to ensuring that growth happens in ways that protect rather than undermine economic opportunities.

3. Honiara, Solomon Islands 🇸🇧
A detailed ”multi-hazard risk assessment” of Honiara found that much of the city’s growth has pushed into flood-prone areas, while the port, airport, and main transport routes face high exposure to natural hazards. The findings highlight the need for better land-use policies that steer housing toward safer areas, stronger building standards, improved drainage, and city-level early warning systems. These measures can help protect the infrastructure and services that Honiara’s jobs depend on.

Why This Matters: Beyond the Pacific
The World Bank Group’s three-pillar approach to job creation — investing in foundational infrastructure, supporting business-friendly policy reforms, and mobilizing private capital — all depend on a basic prerequisite: that the environment is stable enough for investment to make sense.
Urban resilience diagnostics directly support all three pillars. They identify which infrastructure investments will hold up over time. They give policymakers an evidence base needed to reform land-use and building regulations. And they provide the kind of risk transparency that private investors need before committing capital to a market.
This is a model with relevance well beyond the Pacific. In any country where climate risk threatens urban economies, understanding that risk with precision is the first step toward creating the conditions for durable job growth. Resilient cities are not just safer — they are more productive, more attractive to investment, and better able to deliver on the promise of good jobs for their people.
