Beyond the Mirage
By 2050, Lagos will be home to almost 40 million people, larger than many entire countries, yet today half of its residents cannot access clean water or reliable power. So when Nigerian leaders announce glossy “smart city” projects in Lagos, Abuja, or smaller states, the public is right to ask: are we witnessing a genuine plan for the future or just another scam dressed in steel and glass?
The phrase “smart city” has been repeated so often that it now evokes skepticism rather than hope. Most Nigerians know the pattern: big press conferences, ribbon cuttings, promises of digital utopias, but little delivery. Yet the problem is not that smart cities are impossible. It is that they are often announced without credible planning, realistic financing, or expert oversight.
Here lies the opportunity for the diaspora. Across the world, Nigerians are leading as urban planners in New York, transport engineers in Toronto, architects in Dubai, and civic technology experts in London. They have the knowledge and global exposure to design livable, sustainable, tech-enabled African cities. The question is whether Nigeria will continue recycling hollow announcements or whether it will harness diaspora brains to build cities fit for 2050.
Nigeria’s Urban Explosion: The Numbers That Cannot Be Ignored
Nigeria’s population is now over 220 million and projected to hit 400 million by 2050, making it the third largest country in the world. What is more urgent is the pace of urban growth. In 1960, only 15 per cent of Nigerians lived in cities. Today, more than 52 per cent are urbanized. By 2050, over 70 per cent will live in cities, more than 280 million people.
This transformation is staggering. Lagos alone is expected to expand from 22 million to nearly 40 million residents, making it one of the world’s largest megacities. For comparison, that is bigger than the current population of Poland and Canada combined.
The implications are profound. According to the World Bank, Nigeria must invest at least $3 trillion in infrastructure by 2050 just to keep pace with demand. Without intervention, the country faces sprawling slums, gridlocked roads, water shortages, and climate-driven crises. The current piecemeal approach of depending on foreign loans or politically convenient contractors is not sustainable. Nigeria needs structured diaspora capital, planning expertise, and governance innovation.
Smart City or Smart Scam?
Globally, smart cities are about integrating technology with governance and urban planning to improve quality of life. They mean efficient transport, renewable energy, real-time data for traffic and security, inclusive housing, and sustainable water systems.
Nigeria’s attempts, however, often devolve into real estate ventures cloaked in buzzwords. Eko Atlantic City in Lagos, while visually ambitious, has been criticized for catering primarily to the wealthy, disconnected from the lives of ordinary Lagosians. Abuja’s constant announcements of satellite cities rarely move beyond land deals. The outcome is that “smart city” becomes shorthand for elitist enclaves rather than inclusive innovation.

This is why diaspora engagement is critical. A truly smart city in Nigeria cannot just be about Wi-Fi-enabled towers. It must address real needs, transport for millions, affordable housing, safe water, sustainable energy, and resilience against flooding and climate shocks. Anything less is not smart but a scam.
What Would It Take? Calculations for a 2050 Nigeria
To prepare for the urban future, let us look at some numbers:
Housing: With 180 million more urban residents expected, and assuming just 20 square meters of space per person, Nigeria will need an additional 3.6 billion square meters of housing by 2050. That equals building seven million two-bedroom apartments. Put differently, Nigeria must construct the equivalent of a new Abuja every year for the next 25 years.
Transport: If 30 per cent of urban dwellers require mass transit, that means 54 million daily commuters. To meet this, Nigeria would need to roll out the equivalent of a Lagos Metro system every five years until 2050.
Water: At 50 litres per person daily (WHO standard), 280 million urban residents will require 14 billion liters per day. Current capacity is far below even half that figure.
These are daunting, but they also reveal the opportunity. If diaspora-backed urban investment funds and advisory councils are embedded into national and state planning, Nigeria can turn these numbers from nightmares into blueprints. The diaspora has seen how Singapore transformed from swamplands into one of the world’s most efficient cities within 50 years. Nigeria can achieve the same, but only with deliberate strategies.
Diaspora Brains as Urban Blueprint Designers
Nigeria’s true strength lies in its people, and many of its brightest urban minds are abroad. Nigerian-born architects have contributed to projects in London’s financial district, engineers are designing bridges in New York, and civic planners are leading data-driven city initiatives in Canada.
Imagine if even a fraction of this expertise was systematically connected to Nigeria’s urban agenda. Local governments could establish Diaspora Urban Advisory Councils to provide 25- to 50-year city plans that outlive election cycles. National frameworks could mandate diaspora technical audits for every new megacity project. Diaspora investment syndicates could fund pilot models, solar-powered neighborhoods, modular housing prototypes, or AI-driven traffic systems, that could be scaled nationally.
In Kenya, diaspora remittances have already been pooled into cooperative housing projects. In India, diaspora engineers advised on Bangalore’s metro expansion. Nigeria does not lack models, it lacks the willingness to tap them.
Avoiding Elitist Urbanism
A central risk is that Nigeria’s cities become playgrounds for elites while millions are excluded. Luxury apartments, gated estates, and exclusive commercial spaces dominate new developments, while the majority struggle with poor transport and water shortages. This is not just socially unjust, it is economically foolish. Cities thrive when they work for the many, not the few.
Diaspora voices, shaped by global exposure, can push for inclusivity. In Toronto, Singapore, and Berlin, affordable housing is not an afterthought but a backbone. Nigeria must replicate this thinking. Imagine if each of Nigeria’s 774 local governments was tasked to develop a livable, tech-enabled hub for 500,000 people by 2050. That would distribute growth, reduce pressure on Lagos and Abuja, and create a network of medium-sized cities anchored by diaspora expertise.
Strategy and Policy: Turning Ideas Into Systems
To move from vision to reality, Nigeria needs systems that embed diaspora input structurally, not occasionally. Three strategies stand out:
- Diaspora Urban Fund – pooling remittances into a transparent vehicle dedicated to urban infrastructure and housing projects. Even if 1 million diaspora Nigerians invested $1,000 annually, that is $1 billion a year toward long-term projects.
- Mandatory Diaspora Technical Review Boards – every “smart city” project should pass through independent diaspora-led panels to assess feasibility and accountability.
- Urban Skills Pipeline – a deliberate programme to pair diaspora experts with local universities and government planning departments, ensuring skills are transferred rather than hoarded.
Nigeria is running out of time. By 2050, the urban wave will be unstoppable. The question is whether it will drown us in slums and failed infrastructure or lift us into livable, competitive cities. Smart cities can be real solutions, but only if designed with integrity, inclusivity, and foresight. Without diaspora brains, they risk being nothing more than smart scams.
Call to Action
Nigeria’s diaspora professionals, architects, engineers, technologists, financiers, must stop waiting for retirement or invitations. The next 10 years are decisive. Whether you sit in Toronto, Dubai, or London, your expertise is not just useful, it is urgent. If you stay silent, you will be complicit in the scams of tomorrow. If you step in now, you can help design the cities of 2050 that will define Nigeria’s destiny. The blueprint is waiting, the question is, will the diaspora draw it?
