Agriculture en zones arides

Les régions semi-arides et arides sont souvent appelées terres arides et sont situées dans le Sahel africain ' , l'Afrique du Nord, le Moyen-Orient et sur la côte pacifique de l'Amérique du Sud. Ces zones sont caractérisées par de faibles précipitations annuelles et abritent généralement des groupes de pasteurs/éleveurs. L'une des principales préoccupations agricoles des zones arides est l'emplacement et l'utilisation efficaces de ressources limitées
