Desert Connections

Preview

‘Desert connections’ looks at how deserts interact with the rest of the world. Deserts are integral to the total Earth system. Dust from the Sahara is blown to southern Europe where it is important for soil, but this dust also finds its way to the Caribbean, where it places disease-spreading spores in coral reefs. Desert resources such as salt and dyes have been important to human societies for millennia. Today's desert exports — minerals and fossil energy — are just as valuable. Desert ideas and lifestyles are key to human behaviour; the domestication of plants and animals, cities, first civilizations, and three world religions all began in deserts.
