Khadin is a system of water harvesting. It is a method used in Rajasthan.
Is a low mound like structure, approximately 1.2 to 1.9 mts high, built on the lower three sides of an agricultural field. The low barrier collects water and allows it to spread on the agricultural filed. The percolation of water increases the soil moisture. This, in turn, increases the average crop yield.
Khadins constructed by the government are typically 8 ft in height and several mts in length and are only benefical to bug and owners. Khadins designed by GRAVIS specifically benefit mardinal farmers with small land holdings. The smaller khadins are 3.5-5 ft tall and 500-1500 ft in length. A built-in wastewier allows for an equitable distribution of water.
