Dryland Farming
Semi-arid and arid regions are often referred to as drylands and are located in Africa's Sahel, North Africa, The Middle East, and the Pacific coast of South America. These areas are characterized by low annual rainfall and are typically home to pastoralists groups. One of the main agricultural concerns for drylands is the efficient use and placement of limited resources.
