Exploration and travel – Routes through the deserts
and savannahs
Crossing regions with little water or no water at all presents human beings with a great challenge. How can the traveller find the right route in an uninhabited region, how can food and water requirements be met, how can he avoid the most difficult areas? These were questions that had to be answered by both prehistoric travellers in the largely uninhabited eastern Sahara and those forming part of a present-day caravan through this desert, the largest in the world. Information about favourable routes was passed on from one generation to the next and is still extremely valuable today. Stores of water and food, a clear-headed assessment of the transport technology available and a realistic appraisal of their own strengths are part of the essential equipment of those who cross the desert successfully.
