The answer is clearly yes, if we look at the population density map.

PoPulation density in the sahara

n°14Jan 2015

Is the Sahara-Sahel as empty as it is often described? The answer is clearly yes, if we look at the population density map. There are less than five persons per km2 between the densely populated areas of the Mediterranean coastline and the moderately populated Sahelian countries to the south - this is to say, a “human desert”. However, the Sahara appears to be much less empty if we calculate the population density per km of roads or trails. This representation also shows much higher densities in the north and the South. Within the so called “empty” areas, some significant population densities appear along the roads. For the Sahara-Sahelian people, the notion of territory is attached to the road. While the vast territories between these roads are of relatively little importance, a large number of cities are set up around this network of roads. It is important to keep in mind that the majority of Saharo-Sahelian people are urban dwellers.

densités de PoPulation au sahara

Le Sahara-Sahel est-il vide comme on le dit souvent ? Oui, si l’on

en croit la carte des densités de population au km². Entre les zones peuplées de la côte méditerra-néenne et du sud des pays sahéliens, on ne trouve que moins de cinq personnes par km², c’est-à-dire un désert humain. Mais si l’on calcule le nombre d’habitants par km de route (ou de piste), on obtient une image différente. Cette représen-tation montre également des densités beaucoup plus fortes au nord et au Sud. Cependant, on voit apparaître sur l’espace réputé vide, des densités significatives de population concen-trées le long des routes. Pour les Saharo-Sahéliens, le territoire est rattaché à la route. Ce qu’il y a entre les routes a peu d’importance. Sur ce maillage de routes, s’inscrit un grand nombre de villes et il faut garder à l’esprit que la majorité des habitants de cette zone sont des urbains.
