The Aflaj Irrigation Systems in Oman, recognized as a UNESCO World Heritage Site in 2006, are an ancient network of falaj (plural: aflaj) that date back over 2,000 years. These traditional systems utilize gravity to transport water from underground aquifers to irrigate fields and support agriculture in arid regions. The aflaj exemplify the ingenuity of Omani engineering and demonstrate sustainable water management practices that have been vital for rural communities.
