Falaj is an ancient irrigation system used primarily in the Arabian Peninsula, particularly in countries like Oman and UAE. It consists of a network of underground and above-ground channels that transport water from natural sources, such as springs or mountains, to agricultural fields. This method allows for efficient water distribution in arid regions, supporting agriculture and sustaining local communities. The Falaj system is recognized for its engineering ingenuity and sustainability. It often features a series of small, controlled channels that help manage water flow and minimize evaporation. Many Falaj systems are still in use today, reflecting traditional practices that have been passed down through generations.
