Water is the essence of sustainability in an arid climate and hence I have named this blog in honor of this amazing and ancient Iranian method for transporting water.
A qanāt (from Arabic: قناة, in Persian: کاریز kariz) is a water management system used to provide a reliable supply of water for human settlements and irrigation in hot, arid and semi-arid climates.

| Qanat Niavaran in Iran |
Qanats are also called kārīz (or kārēz from Persian: كاريز) (Iran, Afghanistan, Pakistan and Central Asia, derived from Persian: كاهریز), kahan(from Persian: کهن), kahriz/kəhriz (Azerbaijan); khettara (Morocco); galería (Spain);falaj (United Arab Emirates and Oman); Kahn (Baloch) or foggara/fughara (North Africa). Alternative terms for qanats in Asia and North Africa are kakuriz, chin-avulz, and mayun. Common variants of qanat in English include kanat, khanat, kunut, kona,konait, ghanat, ghundat.
The qanat technology is known to have been developed by the Persian people sometime in the early 1st millennium BC and to have spread from there slowly west- and eastward.
The value of a qanat is directly related to the quality, volume and regularity of the water flow. Much of the population of Iran and other arid countries in Asia and North Africa historically depended upon the water from qanats; the areas of population corresponded closely to the areas where qanats are possible. Although a qanat was expensive to construct, its long-term value to the community, and thereby to the group that invested in building and maintaining it, was substantial.1
Water is the first sustainer of life, human life, wild life and the biosphere. It sustains agriculture and thereby food security. The purpose of this blog is to advocate, teach and demonstrate holistic ways of designing human environments and creating self sustaining communities using Permaculture techniques.
