A desert is a landscape or region that receives an extremely low amount of precipitation, less than enough to support growth of most plants. Most deserts have an average annual precipitation of less than 400 millimetres (16 in).[1] A common definition distinguishes between true deserts, which receive less than 250 millimetres (10 in) of average annual precipitation, and semideserts or steppes, which receive between 250 millimetres (10 in) and 400 to 500 millimetres (16 to 20 in)

(from Wikipedia)

Traveling in the desert requires different techniques and equipment than other climates. Dehydration, heat stroke and flash floods are some of the problems that travelers need to be aware of when trekking across deserts.
