Deserts as Corridors

CROSS-DESERT TRANSPORTATION OF GOODS AND CULTURES

CROSS-DESERT ANIMAL MIGRATION

The common denominator of trading caravans and migratory birds is that both use deserts only as corridors linking non-desert starting points with non-desert destinations. however, while using the desert corridor, both often interact with the desert environment, its biota and its human population. And, just as desert corridors have been used by armies to reach their non-desert destinations for assault, so it is often the case with locusts that use deserts as a corridor for invading non-desert areas.
