Dryland areas occur widely in all countries of the world. Thirty - eight percent of the world's land surface is classified as semi-arid or dry subhumid. The growing of crops in such regions is ofter referred to as dryland agriculture. The challenges of crop production in dryland areas are far greater than those in the more favored climatic regions. Dryland agriculture is sometimes used synonymously with rainfed agriculture, but the only commonality is that there is no irrigation. In reality, dryland agriculture is a subset of rainfed agriculture.
