How khadin system prevent mosqutioes breeding |
| Answer» The \'Khadin\' system of rainwater harvesting was practiced in ancient times in Rajasthan. In this system, a very long (about 100 m - 300 m long) earthen embankment called \'Bund\' is built across the lower hill slopes lying below gravelly uplands. The rainwater from the catchment area is made to flow down the slopes and stopped by the \'Bund\' to form a reservoir. The rainwater collected in the reservoir formed by the \'Bund\', and in the well, gradually penetrates into the land (or ground) so it does not allow mosquito breeding. | |
