Through this technique all the accumulated water in village tank above 50% full supply level would be recharged to ground water. Recharge shaft may be dug manually if the strata are of non-caving nature. Paradoxically, as the natural resources began providing less of their formerly reliable services, pressure on them intensified.

Construction material such as bamboo and fiber is locally available.

Village wells had dried up completely, and urban migration had reached a peak of 3-4 people from each family. Sometimes, several johads are interconnected through deep channels, with a single outlet opening into a river or stream nearby. The tanks are interconnected in order to enable access to the farthest village and to balance the water level in case of excess supply. The driver was Mangu Patel. EcoTipping Points as a Conceptual Point of Departure There is overwhelming evidence that the great self-balancing system of nature is becoming increasingly unbalanced.
