This article by Kurtis Lockhart for Asterisk Magazine argues that Africa, on the cusp of the largest wave of urban growth in human history, needs a "YIMBY" (Yes In My Backyard) movement to ensure this transition fuels economic prosperity. The author highlights that Africa is currently "urbanizing while poor," with its rapid urban growth decoupled from the significant income gains seen in other regions. This is exacerbated by severe institutional and regulatory barriers, such as outdated zoning laws and complex permitting processes, which fragment cities and stifle growth. The author proposes a three-pronged solution focused on the core factors of production: (1) adopting proactive, simplified urban expansion planning for land; (2) implementing innovative land value capture mechanisms like tech-enabled property taxes for capital; and (3) investing heavily in building the capacity and skills of local urban planners for labor. These urgent policy interventions are presented as critical to unlocking the continent's potential and shaping its development for generations.
Building Africa's Future: A YIMBY Approach to Urbanization
The Unprecedented Challenge: Africa is projected to add 900 million new urban residents by 2050, the largest and fastest wave of urban growth in history. Two-thirds of the continent's estimated urban space for 2050 has not yet been built.
The Growth Disconnect: Unlike historical precedents, Africa's urbanization is currently "decoupled" from significant economic growth. The continent is "urbanizing while poor," with much lower per capita income at its 40% urbanization threshold ($1,481) compared to East Asia ($5,400) or the US ($4,500).
Regulatory & Governance Hurdles: Growth is stifled by a web of onerous regulations, many of which are colonial-era relics. Examples include excessively large minimum plot sizes in Dar es Salaam, which push residents into slums or far-flung suburbs, and building codes in Nairobi that once required roofs to withstand snow.
The High Cost of Poor Planning: Fragmented cities lead to localized labor markets, blunting the economic benefits of density. The high cost of living makes firms less competitive; for instance, unit labor costs in Dar es Salaam are 20% higher than in Dhaka, Bangladesh.
Solution 1 - Land: Proactive Urban Expansion (UX) Planning: Instead of creating complex master plans that are rarely implemented, cities should adopt a simple, proactive approach. This involves planning an arterial road grid in designated expansion areas before settlement occurs.
Key Takeaway: This method is three times cheaper than retrofitting infrastructure and has been proven effective in Ethiopia, where it led to higher incomes and shorter commute times.
Solution 2 - Capital: Land Value Capture & Property Tax: African cities are severely under-resourced. They can generate their own revenue by taxing the huge increases in land value created by urbanization.
Key Takeaway: Modern technology can simplify property tax systems. Freetown, Sierra Leone, successfully used satellite imagery and mobile payments to quintuple its property tax revenue, which in turn improves its ability to access affordable external capital for larger projects.
Solution 3 - Labor: Boosting Planning Capacity: There is a critical shortage of skilled urban planners across the continent (0.89 per 100,000 people vs. the OECD average of 21.5). Furthermore, university planning curricula are often severely outdated.
Key Takeaway: Investing in modern training and increasing the number of skilled local planners is essential for drafting and executing effective urban plans.
Conclusion - A Call to Action: The author concludes that an Africa-focused YIMBY movement should champion these three solutions—proactive planning, property tax reform, and capacity building—to ensure the continent's urban future is prosperous and sustainable. The policy choices made in the next generation will lock in Africa's development trajectory for decades.
