Khadeen is a most multi-purpose method of water conservation in Rajasthan.
It was first developed in the 15th century in the Jaisalmer district.
The run-off from upland and rocky surfaces is collected in a Khadeen from the adjoining valley against an embankment having a masonry water barrier for the outflow of runoff excess.
The standing water in a Khadeen assists continuous groundwater recharge.
On the Khadeen bed, at least one crop is cultivated even in the arid region as it retains moisture and contains fine and fertile soil.
In the immediate vicinity downstream the sub-surface water is extracted through bore wells.
