Arabian Mountain Adaptation

People have been living in the mountains for thousands of years. In the 6th century many people lived in the Asir Mountains, the people there farmed on the steep slopes by making terraces. The farmers also made damns and irrigation syatems. Also, they collected rain water, leather bags, and hollowed-out trees. To fertilize the soil they probally used manure and ashes. Mountain life hasnt changed much since then.
