1.2.1. What is a desert?
Different people will have different answers to this question based on their experience and imagination.
When Fénelon3 exclaimed, “But look! The most beautiful desert you could ever see. Do you not marvel at these streams that fall from the mountains, these steep rocks?”, he was, clearly, singing the praises of one of those wild retreats of which his contemporaries would often dream. Modern-day travel agencies celebrate a more truthful picture of a desert – bare landscapes, a sea of sand and five-star bivouacs. The Paris–Dakar Rally racers, whose tracks despoil the Saharan landscape with impunity, bring to television audiences the idea of a threatening desert: devious, enchanting and sometimes deadly! A place demanding courage and renunciation.
Indeed, the Sahara, so close to Europe and featuring in desert tales so often, is what Europeans use as the model for their concept of a desert: a vast mineral landscape, no water, no trees, sand, pebbles, nomads and camels. Majestic dunes, picturesque oases, treacherous mirages, outright fabrications and howlers – all these feature in most accounts of deserts, such as Théodore Monod’s Méharées. However, the North American conception of deserts is very different: there is the desolate Death Valley, the high plains in Arizona and Utah with their monoliths, arches, their dry rios, their candelabra cacti, their prairies, the Native Americans and their horses. In Central Asia, the deserts include the steppes, in southern Africa you have the dull sands of the Kalahari dotted with trees, and the vast white lakes, the inconstant giant rivers, the interminable shifting of the red dunes of Australia with eucalyptus, aboriginal settlements, sheep and cattle rearers, remote farms, the rabbit-proof fences, the kangaroos and their dry bush that can turn into green pastures in a rainy year.
The desert is all this and more. There are populated deserts, as in Mesopotamia and Egypt, or barren, lifeless deserts such as the Tanezrouft and Lut. There are dry deserts, such as the Libyan desert, and foggy deserts such as the Namib or Atacama deserts. And to these we must also add the frozen deserts found in high mountains and the polar regions. In fact, by this definition, the Antarctic is the largest desert in the world.
A desert is, above all, a vast region that is empty, dry and outside time. T. Monod described it as “the kingdom of absence”. It is a land of surprises, contrasts and oppositions that can occur far apart or close together, sometimes spread out over years, at others separated by barely a few hours. There is the Asian desert, where you broil in summer and freeze in winter, and there is the African desert, where all the days are torrid and all the nights are cold. There is the arid desert, containing opulent oases, while you have a desert enclosed within vegetation. There are deserts that are endlessly flat, as far as the eye can see, and there are plains with rocky islands or bleak mountains. There is the sudden downpour that breaks the monotony of waterless days, and the dry river that swells into a flood. You have the bare desert that transforms, with the rain, into a carpet of flowers. And there is the seemingly uninhabited desert – where as soon as you stop, someone pops up out of nowhere to look at you and to converse.
A desert is also a bare spot that is ideal for contemplation and spirituality, where Man finds himself alone in the face of this immensity, silence and beauty. It is the void, where all fundamental questions arise. It is the Biblical antithesis to the Promised Land. It is the site of fervor, where altars are built and sacrifices made, such as the sacrifice of Abraham; the sacred land where divinity approaches humanity, the land of Moses, Jesus, Mohammed and the Buddha. It is the chosen site for renunciation and retreat, from the medieval monks to the 19th Century Father Charles de Foucauld. It is the site of exaltation, the site of gigantic temples, as can be seen in Babylon, Egypt, Syria, Tibet and in the Andes. It was also the backdrop for adventurers and empire-builders, from Alexander the Great to Genghis Khan, and from the Incans to the conquistadors of the Andes and Mexico. It has served as the arena of war from Libya to Iraq, and the testing ground for the atomic bombs. It is fertile ground for prospectors and operators, the salt-miners of the Sahel and the gold-hunters in the Americas, as well as modern-day oil seekers. Finally, deserts have also served as an observatory for the curious, such as Ibn Battuta and Marco Polo, offered new horizons to explorers, such as Caillé and Barth in the Sahara, Prjevalski and Sven Hedin in Asia, Powell in the Colorado and Eyre in Australia, and been used as a research field for scholars, such as Stein in Chinese Turkestan or Monod in Mauritania.
The desert is also a land of legend, exoticism and dreams, brimming over with fantasies and received ideas. Of course, this aspect of it is slowly diminishing as scientific discoveries and analyses progress and with the increasingly widespread sharing of images from these regions. The Romantics turned the desert into a mysterious land, overwhelmed by light and heat, throwing up strange mirages and sandstorms that could bury entire caravans. It was a hellish land of thirst and wind, of silence and death, that was both fascinating and horrifying. In the colonial period, th...
