Aflaj are traditional irrigation systems found in the Arabian Peninsula, particularly in Oman and UAE. These systems consist of a network of underground channels that transport water from natural springs or aquifers to agricultural fields. The design of aflaj allows for efficient water distribution, supporting farming in arid regions. The word "aflaj" is derived from the Arabic term for "to divide," reflecting how water is shared among different users. This ancient technique has been recognized by UNESCO as a vital part of cultural heritage, showcasing the ingenuity of communities in managing scarce water resources.
