C new irrigation techniques.
Many lands in the Arabian Peninsula, which is characterized by an arid climate, have been turned into agricultural zones through the development of new irrigation techniques that make it possible to cultivate crops in otherwise dry regions. These innovations include the use of drip irrigation, which saves water by delivering it directly to the base of each plant, and the use of treated wastewater for agriculture. Advances in desalination technology have also played a role in providing fresh water for agriculture in the region.
