The Next Urban Frontier: Africa’s Intermediary Cities
By 2050, Africa will be home to more urban residents than any other continent. Yet how this urban growth unfolds, and which cities drive it remains an open question. While megacities such as Cairo and Lagos largely dominate headlines and policy agendas, it is the continent’s intermediary cities that will quietly shape the reality of Africa’s urban future. Accommodating between 100,000 and 1 million residents, intermediary cities are often dense enough to support services and industrial clusters, small enough to remain administratively agile, and geographically positioned to support regional supply chains. They are also areas in which a large bulk of the continent’s population will live and work in the decades ahead. Despite this potential, many intermediary cities across Africa face significant infrastructure deficits, fragmented urban systems and weak institutional capacity that prevent them from fully capitalising on agglomeration effects and driving inclusive economic transformation.
In Egypt, this story is playing out along the Nile River corridor, where a chain of intermediary cities form a dense yet under-integrated urban spine. Historically important for agriculture, administration, and commerce, these cities are faced with navigating accelerating climate risks while remaining largely disconnected from national and regional trade strategies. These cities are situated in a strategic subregional hub, with relatively low road-to-distance ratios between them, positioning them as potential trade anchors in regional economic integration. However, their strategic value remains largely untapped due to weak coordination mechanisms and limited investment in resilient infrastructure.
The African Continental Free Trade Area (AfCFTA) agreement has unlocked a new opportunity to reframe the role of these cities. As Africa’s most ambitious economic integration effort to date, the AfCFTA envisions a continent where trade flows more freely, supply chains extend across borders, and regional economies rise together. However, trade does not happen in abstract zones, it happens in places – particularly in cities. This presents the question as to whether Egypt’s intermediary cities are prepared to support this new chapter of integration. Given their geographic proximity, cities along the Nile corridor are uniquely positioned to operate as a networked economic system, driving subnational integration and complementing broader continental goals under the AfCFTA.
Uniquely situated, these cities require a coordinated economic system to fully leverage their potential in regional trade integration. Cities such as Minya, Sohag, Qena, Luxor and Aswan operate within their own administrative and planning agenda, often without strategic links to their neighbours. While infrastructure is present, it is largely underfunded, fragmented and outdated, limiting the movement of goods and people, and constraining the very trade flows the AfCFTA seeks to accelerate.
Climate Risk as a Trade Risk
Compounding these governance and infrastructure gaps are mounting climate risks. The impacts of climate change are not distant threats to these cities but immediate pressures. Increasing atmospheric temperatures, water scarcity, and periodic floods are already impacting roads, rail lines, agricultural zones, and water infrastructure. Moreover, due to the region’s linear geography, settlements concentrated tightly along the Nile River, disruptions in one city often cascade to others, weakening the corridor’s overall resilience. The implications for trade are significant; extreme heat can degrade road surfaces, causing transport delays and higher maintenance costs; and flash floods can wash out bridges or cut access to storage and customs facilities. Agricultural supply chains, critical for food security and rural employment, are particularly vulnerable. Local governments will be faced to respond to climate-related disruptions, diverting resources from longer-term investment in trade-enabling infrastructure. In fact, nearly half of Africa’s GDP is considered vulnerable to extreme climate events, with projected losses from temperature increases alone reaching up to 12.12% of GDP. For Egypt’s intermediary cities, climate vulnerability not only threatens physical infrastructure but also undermines trade flows, private sector confidence, and long-term economic resilience.
Unlocking Urban Potential: From Linear Geography to Networked Growth
At the national level, Egypt’s trade and urban policies are still largely disconnected. Trade strategies tend to focus on border crossings, industrial zones, and logistics hubs while urban development planning remains centred on megaprojects or capital-intensive new cities. Intermediary cities fall through the cracks, seen as too small to attract significant investment, yet too large to be considered as rural development targets. Such policy invisibility leaves them exposed to both climate and economic shocks. Yet these cities are far from marginal – their geographic continuity along the Nile offers a rare opportunity for coordinated planning. Transport infrastructure, while in need of upgrading, already exists in the form of road and rail links, and human capital characterised by a young demographic, underemployment, and increasing mobility represents an untapped engine for local and regional growth. Intermediary cities are also increasingly emerging as focal points in urban clusters, which are now recognised as backbones of successful regional economies. Their appropriate scale and adaptability give them comparative advantages to absorb green technologies and manage urban diseconomies more effectively than megacities.
To unlock this potential in Egypt, emerging urban development strategies will be required to rethink their approaches on several fronts. Infrastructure investments should be climate-responsive from the outset, incorporating data on acute risks such as flood zones, heat vulnerability and water availability. Governance must also evolve to support regional coordination among those cities that currently plan and operate in silos, while urban planning must incorporate trade logic; not only planning for housing and transport but for logistics, storage, agro-industrial activity and cross-border flows. Moreover, it is increasingly important for digital transformation to go hand in hand with climate adaptation, enabling these cities to monitor, manage, and optimize trade and mobility in real time.
This is not a hypothetical agenda. Around the world, intermediary cities are beginning to show how green, smart, and regionally connected models of development can work in practice. In Colombia and Vietnam, smaller cities are leading efforts to integrate environmental resilience with economic competitiveness. Egypt’s Nile corridor cities possess the foundations to follow suit if they are provided the adequate policy tools and institutional frameworks to do so. These cities must be understood not just as urban spaces, but as vital nodes within wider economic and ecological systems.
Intermediary Cities as Strategic Nodes for Regional Trade Integration
The AfCFTA gives this challenge renewed urgency. If intermediary cities are overlooked in national plans, Egypt risks entering this new era of African trade with fragmented urban systems and vulnerable infrastructure. Without improving their ability to connect firms to markets and workers to firms, regional integration goals will likely fall short, reducing the competitiveness of Egypt’s southern trade corridor. Yet via targeted investment, smarter governance, and climate-informed planning, these cities can become the linchpins of a new, greener regional economy.
In many ways, the AfCFTA is therefore not only a trade deal, but also a test of how countries such as Egypt can integrate urban development, climate adaptation and regional cooperation into a single, coherent strategy. Critically, intermediary cities – long seen as peripheral, may hold the key to success.
