In practice, the technology works. The question is not whether smart waste collection is technically viable — it is. The question is whether it is viable for a specific city, with its specific infrastructure, fleet, budget, and operational context. And that is a very different question. What the technology actually involves Before assessing viability, it is worth being precise about what "smart waste collection" means…
The principle is simple but revolutionary. Instead of following preprogrammed schedules, AI-controlled traffic lights use machine learning algorithms to analyze data from sensors, cameras, and connected vehicles. These systems detect vehicle density, speed, and flow direction, as well as pedestrian crossings and environmental factors such as weather or time of day. The AI then adjusts signal timings dynamically, optimizing each intersection to minimize waiting time…
The growing accumulation of waste, the chronic insufficiency of sanitation systems, and the accelerating pace of urbanization are converging to create a persistent and deeply structural crisis of urban cleanliness across many African cities, a crisis that, while often perceived primarily through its visible environmental and social impacts, in reality conceals a far more complex and economically significant phenomenon that directly affects productivity, public finances,…
The growing intensity and frequency of heatwaves across Europe, driven by accelerating climate change and the structural characteristics of dense urban environments, has placed the mitigation of urban heat at the center of contemporary urban policy and planning debates, particularly as cities increasingly face the dual challenge of protecting public health while maintaining livability and economic productivity under extreme climatic conditions. Within this context, a…
The successful flight of an unmanned electric aerial vehicle in Kigali in September 2025, carried out during the 9th Aviation Summit in Africa, cannot be understood merely as an isolated technological milestone, but rather as a carefully orchestrated entry point into a rapidly evolving global market in which urban air mobility is beginning to redefine the spatial and economic logic of transportation systems, particularly in…
The 2026 edition of the Smart City Index, developed by the IMD World Competitiveness Center, marks a decisive conceptual shift in the global understanding of what constitutes a “smart city,” moving beyond the long-dominant narrative that equates urban intelligence with the density of sensors, the scale of digital platforms, or the sophistication of technological infrastructure, and instead placing the emphasis on governance quality, institutional coherence,…
In the contemporary urban context of many rapidly growing African capitals, the condition of road infrastructure emerges not merely as a technical or logistical concern, but as a defining factor in the viability of economic systems, the cohesion of social structures, and the credibility of public governance, and in the case of N’Djamena, the capital of Chad, this reality becomes particularly visible, as the progressive…
