We want to describe and introduce some traditional methods for growing crops with minimum irrigation and even with no irrigation, once practiced in the Iranian desert. We have classified these methods into three categories as follows: 1- thorn-based cultivation: in this method such crops as cucumber or watermelon can live off the moisture being secreted out from the vascular system of some desert plants. 2- pottery irrigation: in this method the crop can be irrigated just by the minimal water seeping through a clay membrane into the soil according to osmotic pressure. 3- flood irrigation: the flash floods can be controlled and harvested behind the earthen dams in order to increase the soil moisture. Some crops can be grown behind the dams after the water would percolate the earth.

Guilspare is anorganic autodegradable polymer in a liquid form that farmers mix at 1 to 2% concentration to first irrigation water. Once in contact with air,Guilspare coats the particles of the soil on a few centimeters depth. The virtual film will prevent water from evaporation by capillarity, while gravitational water will keep on passing through.

The role of mountains in providing indispensible water resources for municipal and industrial water supply, irrigation, hydropower production, and other environmental services is well-known and unquestioned (e.g., Barnett et al. 2005; EEA 2009; Viviroli 2003, 2007).
Furthermore, several studies have also underlined the sensitivity and vulnerability of these mountain ecosystems to the impacts of climate change (Beniston 1994; Diaz et al. 1997; COM 2009).
