The Growing Imperative for Smart Cities in Africa

Africa stands at the cusp of an unprecedented urban transformation. Currently, over 40% of the continent's population resides in urban areas, a figure projected to surge to 60% by 2050, adding nearly 950 million city dwellers. This rapid urbanization promises economic vitality but also amplifies challenges like inadequate infrastructure, housing shortages, unreliable energy supply, and widening inequality. In South Africa, where 67% of the population is already urban, cities like Johannesburg grapple with load shedding, high crime rates, and spatial legacies of apartheid.

Smart cities—leveraging Internet of Things (IoT) sensors, data analytics, artificial intelligence (AI), and connected infrastructure—offer potential solutions for efficient service delivery, sustainable resource management, and enhanced public safety. However, top-down implementations often fail to address local contexts, leading to exclusionary outcomes that exacerbate divides rather than bridge them. Enter the University of the Witwatersrand (Wits), where researchers are pioneering community-centric approaches to redefine smart urban development.

Wits University: A Hub for Urban Innovation Research

The University of the Witwatersrand, Johannesburg's premier research institution, has long been at the forefront of addressing Africa's urban challenges through its interdisciplinary programs. The School of Business Sciences, in particular, under leaders like Professor Rennie Naidoo, Research Director and Professor of Information Systems, integrates technology with social sciences to foster inclusive innovation. Naidoo's work emphasizes human-centered design, drawing from global best practices while grounding them in African realities.

Wits hosts initiatives like the Smart Cities Lab, launched in collaboration with the Gauteng Department of Infrastructure Development (DID), Cooperative Governance and Traditional Affairs (CoGTA), and Greater Johannesburg Improvement Districts Association (GIFA). These platforms convene government, academia, and private sector stakeholders to co-create African-relevant smart city strategies. Recent events, such as the 2025 Smart Cities Lab, highlighted human security, digital infrastructure, and sustainability, underscoring Wits' role in policy influence.

The Participatory Futures Method: A Novel Co-Design Framework

Central to Wits' contributions is the Participatory Futures Method (PFM), developed collaboratively by Professor Rennie Naidoo and Terence Fenn, a PhD researcher affiliated with the University of Johannesburg and University of Pretoria. Published in the Journal of Community Informatics, PFM fuses experiential futures techniques with generative design tools to empower resource-scarce communities in envisioning smart urban spaces.

Unlike traditional Design Science Research—typically applied in corporate settings for profit optimization—PFM prioritizes relevance through grassroots participation. It involves iterative workshops where residents map neighborhoods, craft narratives, and prototype artifacts, iteratively refining visions. This step-by-step process—mapping current realities, imagining desired futures, integrating technology supportively—ensures outputs are culturally resonant and feasible. As Naidoo notes, "Technology must enhance lifestyles without widening inequalities; smart communities scale to smart cities."

Case Study: Transforming Westbury Through Community Co-Design

Westbury, a vibrant yet challenged neighborhood west of Johannesburg's CBD, served as the pilot site. Shaped by apartheid-era designations, it faces high unemployment, gang violence, and power outages, yet boasts strong cultural ties and resilience. In workshops with 30 diverse residents—spanning ages, genders, and backgrounds—PFM elicited bold visions.

Participants rejected surveillance-heavy systems, preferring locally controlled smart cameras for reclaiming streets. Energy self-sufficiency emerged via solar-powered resilience hubs to combat load shedding. Cultural precincts with augmented reality (AR) overlays of local history and art were proposed, alongside digital centers for coding, music production, and global art showcasing. Recycling kiosks and culture-focused streets underscored priorities beyond basic needs: creativity, safety, and ubuntu (community interconnectedness).

Key Outcomes and Innovations from Westbury

• Safety Solutions: Community-managed IoT surveillance to deter crime without eroding privacy.
• Energy Resilience: Solar hubs enabling off-grid power, charging stations, and micro-grids during blackouts.
• Cultural Vitality: AR apps mapping neighborhood stories, fostering pride and tourism.
• Skills Hubs: Tech-enabled spaces for vocational training, entrepreneurship, and creative industries.

These ideas, rooted in residents' hierarchies of needs, reveal how co-design uncovers latent desires. As one participant envisioned, tech-enabled community centers as "hubs of empowerment." The process yielded trusted, scalable prototypes, proving small interventions can transform lives.

Critiquing Top-Down Approaches in South African Contexts

South Africa's smart city efforts, like Johannesburg's City of 68 Districts and Cape Town's Smart City Framework, show promise but often falter on inclusivity. Mega-projects such as Lanseria Smart City prioritize elite developments over townships. Durban's aerotropolis and Ekurhuleni's Huawei partnerships focus on infrastructure but risk bypassing communities.

Naidoo critiques governmental disconnect: "Politicians must engage constituents in representative democracy." Co-design counters this by embedding local agency, ensuring tech serves ubuntu rather than corporate or state agendas. For SA universities, this model aligns with National Research Foundation (NRF) priorities on AI in higher education and urban resilience.

Broader Collaborations: Africa-US Smart Cities Lab and Beyond

Wits extends impact via the Africa-US Smart Cities Lab, hosted by its African Centre for the Study of the United States. The 2024 inaugural and 2025 editions fostered transatlantic exchanges on policy, governance, and digital infrastructure. Partnerships with DID and CoGTA position Wits as a thought leader, influencing Gauteng's integrated development plans.

Complementing efforts at UCT's African Centre for Cities and UJ's urban research, Wits exemplifies how South African higher education drives context-specific innovation. Stellenbosch University's Immersive Technology Lab visualizes urban scenarios, enriching the ecosystem.

Challenges and Solutions in Implementing Co-Design

Barriers include digital divides, funding shortages, and resistance to participatory governance. Yet PFM's low-cost, iterative nature mitigates these: workshops require minimal tech, leveraging cellphones ubiquitous even in townships. Scaling demands policy integration, like CoGTA's Smart Cities Framework, emphasizing human capital alongside ICT.

• Step 1: Community mapping identifies pain points.
• Step 2: Futures storytelling sparks imagination.
• Step 3: Prototyping tests tech integration.
• Step 4: Iteration refines for scalability.

South African universities can institutionalize such methods via curricula, incubating community labs.

Future Outlook: Scaling Community-Centric Urban Tech

With Africa's urban boom, Wits' models offer a blueprint. Naidoo envisions "cumulative small projects dramatically improving conditions." Policymakers should fund university-led pilots, mandate co-design in tenders, and train planners in PFM. For higher education, this positions institutions like Wits as vital bridges between research and reality, fostering jobs in urban tech and planning.
