The Arabian Desert is Asia's largest desert

Most people name the Gobi as Asia's biggest desert, but the Arabian Desert covers about 2.3 million square kilometres, nearly twice the Gobi's size.

Good morning

On 20 October 1944, American troops landed on Leyte, an island in the Philippines. It was the start of a campaign to take the country back from Japanese occupation. The commander, General Douglas MacArthur, waded ashore and kept a promise he had made two years before: "I have returned."

Today's issue looks at deserts, borders and distant points on the map, from Asia's largest desert to the westernmost tip of Africa.

In today's edition

  • Why most people guess Asia's desert wrong
  • Africa's westernmost point, further west than Europe
  • Brunei's land, split in two by Malaysia
  • A castle that predates Columbus's crossing
  • Two countries, two borders from any sea
  • Match countries across a tricky grid

Arabian Desert · Fact of the day

Asia's largest desert is the Arabian Desert, not the Gobi

Ask most people to name Asia's biggest desert and they will say the Gobi, the dry expanse that stretches across Mongolia and northern China. The Gobi is indeed huge, at about 1,295,000 square kilometres, and it is the largest desert in East Asia.

But Saudi Arabia, Yemen, Oman and their neighbours sit in Asia too, even though we often group them under the separate label "Middle East". Together their desert, the Arabian Desert, covers about 2,330,000 square kilometres, roughly 1.8 times the size of the Gobi. It even reaches past the famous sand sea of the Empty Quarter into gravel plains further north. Once it is counted, it beats the Gobi by a wide margin, and ranks second in the world only to the Sahara.

Pointe des Almadies, Senegal

Pointe des Almadies is a headland on the Cap-Vert peninsula in Senegal, a country on the Atlantic coast of West Africa. It is part of Dakar, Senegal's capital, and it marks the westernmost point of mainland Africa.

Most people picture Africa as lying south of Europe, so they rarely check which continent reaches further west. Mainland Europe's westernmost point, Cabo da Roca in Portugal, sits about 700 kilometres further east than Pointe des Almadies. That means all of continental Europe, including the tip of Ireland, lies to the east of Dakar.

Stand on this headland and the nearest land in a straight line west is Brazil, across the open Atlantic.

History

Ghana's Elmina Castle predates Columbus's Atlantic crossing Elmina Castle sits on the coast of Ghana, in West Africa. Portuguese builders began it in 1482, shipping cut stone from Lisbon. It was finished before any European sailed round Africa's southern tip, and before Columbus crossed the Atlantic.

Geography

Two countries sit two borders from the sea Most landlocked countries touch at least one coastal neighbour. Only Uzbekistan, in Central Asia, and Liechtenstein, in the Alps, do not. From either one, you must cross two other countries just to reach open water.

Brunei's land and people, split in two

Brunei, total area5,765 km²
Temburong, the cut-off part1,305 km²
Brunei, total population440,715
Temburong's population9,444

Brunei, a small country on the island of Borneo, is not one piece of land. Malaysia's Limbang district cuts straight through it, separating the eastern district of Temburong from the rest of the country. Temburong covers close to a quarter of Brunei's land, an area a little larger than Malta. Yet only about 2 in every 100 Bruneians live there. Until a bridge opened across Brunei Bay in 2020, reaching Temburong from the capital meant driving through four border checkpoints in Malaysia. It matters because a country's land and its people do not always spread out evenly.

That's the world
