Arabian Desert

Covering nearly the whole of the Arabian Peninsula, the Arabian Desert spreads across some 2.3 million square kilometres of dune, gravel, and salt flat. At its heart lies the Rub al Khali, the Empty Quarter, the largest continuous body of sand in the world, where dunes can rise higher than 250 metres and march in parallel ridges for hundreds of kilometres. It is a landscape of staggering scale and silence, where the line between sand and sky blurs in the shimmering heat.

The desert occupies a tilted plateau that slopes from the highlands of western Arabia toward the Persian Gulf. Summer temperatures among the highest reliably recorded on the planet, exceeding 50 degrees Celsius, combine with humidity along the Gulf coast to produce brutal conditions. Rainfall is negligible and erratic, yet beneath the sand lie groundwater reserves and, far deeper, the petroleum that has reshaped the modern world. Sabkhas, glistening salt flats, mark places where ancient lakes evaporated, and fossils of hippos testify to a greener Arabian past.

For the Bedouin, the desert was never empty but a homeland crossed by camel along routes binding oasis to coast. The incense trade in frankincense and myrrh once made southern Arabia rich, and Islam itself was born among these sands and the towns at their edges. In the twentieth century, the discovery of oil beneath the Empty Quarter transformed impoverished sheikhdoms into some of the wealthiest states on Earth, even as the deep desert remains among the least populated places anywhere.
