What it is
Channels, often underground, that carry spring or gallery water from the mountain foot to desert oases and fields, shared out in shifts measured by sundials by day and by the stars at night.
Their origin is debated: some dates (Salut, Izki) place them in the Iron Age, c. 1000 BC; others propose an Achaemenid Persian introduction or an earlier local invention. Five Omani aflaj systems have been World Heritage since 2006.
What it led to
- oasis agriculture and towns such as Nizwa and Izki in an arid climate
- communal water management with inheritable shift rights and a water market
- an irrigation model for the Gulf and eastern Arabia
