Facing Climate Emergency, Africa Must Reinvent Its Cities

Due to climate change and pollution, entire neighborhoods and cities on the continent are destined to vanish. A new vision of African urbanism is needed to replace the illusion of the "city without limits."

Sebha is bound to disappear. The capital of Libya's hydrocarbon-rich Fezzan region has become the largest city in the Sahara. For years, it has seen the convergence of public and private capital, and a steady flow of migrants. Subjected to major demographic pressure, the city of the sands is now doomed. Sooner or later, the lack of water will empty it of its inhabitants — and return its territory to nature.

Sebha is not an isolated case. Everywhere, districts and cities face similar fates. Some because of rising water levels, others subject to rampant desertification, mega-fires or repeated cyclones. These are the devastating and unprecedented consequences of climate change, of course, that the latest report from the Intergovernmental Panel on Climate Change (IPCC) has just reminded us of.

But that's not the only cause. By participating in toxic production systems, we have degraded nature and altered climates. At the same time, since the industrial era, we have readily adhered to this crazy fantasy of the limitless city, capable of absorbing ever more inhabitants, without questioning its capacity to meet their basic needs.


​African cities like Los Angeles

Look at Los Angeles: For a long time now, California's largest metropolitan area has not had enough water resources. It gets its water from the Sierra Nevada, nearly 600 kilometers (373 miles) away. Even in one of the richest regions in the world, this infrastructure, which does not care about borders and distances, is running out of steam. Los Angeles has been suffering from water shortages for two decades, a problem out of step with its residents' standard of living.

Africa is home to 86 of the world's 100 fastest growing cities.

In rich countries, the system is breaking down more quickly than we thought. In Africa, it is an absolute emergency. It is the last continent to urbanize, and the one that is doing so the fastest, without a state structure capable of financing the infrastructure that this implies.

Between high birth rates and rural exodus, Africa is home to 86 of the 100 fastest growing cities in the world. At least 79 of them — including 15 capitals — are facing extreme risks due to climate change.

​Kinshasa's floods to Cairo's "urban hell"

The 13.2 million inhabitants of Kinshasa, the capital of the Democratic Republic of the Congo, are already regular victims of flooding. They will be twice as many by 2035. In Ethiopia, the number of city dwellers will increase from 24 to 74 million in the next three decades. Egypt's urban population will then reach 85 million, compared to 43 million today. It's so much growth that the authorities will have to create a new capital to relieve the urban hell of Cairo.

How to provide housing and equipment, roads and transport, drinking water and sanitation at such a sustained rate? It is impossible. Tensions over access to water, energy and telecommunications will increase as cities continue to have needs that exceed their territorial production capacity. Conflict is inevitable. We are heading for disaster.

That is unless we radically change the way we build our world. In Africa as elsewhere, this means first of all putting an end to the illusion of the city without limits. Some, like Sebha, will have to be abandoned to nature, and thousands of new ones will have to be built. But the thinking must be reversed, to find a balance between populations, resources and territories.

The new city must be appropriately sized, limited by its own resources: if a given territory can provide water and energy for 50,000 people, then the future city must not exceed that size.

Nomads not refugees

To do this, we must reconnect with the visible infrastructure of the past, which was part of the landscape, calling for collective governance. This was the case of the Roman aqueducts and also of the Agdal basins, which integrated urban agriculture, as well as the wells located in each neighborhood, as is still the case today in Venice. This is now being tried in Morocco, with the creation of the city of Mazagan, near El-Jadida, which we already know will not have more than 200,000 inhabitants.

The consequences of climate change, demographic pressure and rampant urbanization leave us no choice: Africa must be the scene of the reinvention of the city in the 21st century. And for that, it is urgent that it becomes again a laboratory of architectural and urban experimentation, with all the more legitimacy that it will no longer be, as in the past, a colonial laboratory.

We must decolonize our thinking.

On the contrary, we must tap into what Africa is capable of offering the world through modes of organization, traditional resource management and the use of materials that have fallen into oblivion. This kind of experimentation is, for example, the raison d'être of the Moroccan Pavilion at the Dubai 2020 World Expo. Made of raw earth, the building stretches 34 meters tall, an unprecedented height. More durable than concrete, raw earth, an African material par excellence, also makes it possible to do without air conditioning in one of the hottest places on earth.

If Africa continues to impose urban planning models thought up elsewhere, without a critical dimension, it will end up in chaos. Here too, we must decolonize our thinking and imagine collective organizations that will enable us to adapt to the major displacements that climate change is already imposing on us. It is in Africa that we can learn to be nomads again, so as not to become refugees.

Ukrainian forces have reportedly gained control of the east bank of the River Oski, preparing for an assault on Russia's forces occupying the eastern Donbas region. Russia's army has been almost completely pushed out of the northern Kharkiv region and Ukrainian President Volodymyr Zelensky said the next offensive targeting Luhansk was in the works.

Though Zelensky repeated that victory would only come when Russian forces were completely driven from Ukrainian territory, Kyiv’s forces are working to establish a foothold on the eastern side of the Oskil and liberate the city of Lyman, which was seized by Russian forces in May. Taking the city of 20,000 would represent a major breakthrough, bringing momentum to free other cities in the region, which were occupied this spring.

Central to the tragic absurdity of this war is the question of language. Vladimir Putin has repeated that protecting ethnic Russians and the Russian-speaking populations of Ukraine was a driving motivation for his invasion.

Yet one month on, a quick look at the map shows that many of the worst-hit cities are those where Russian is the predominant language: Kharkiv, Odesa, Kherson.
