A look at the traditional water harvesting techniques used across the country.india Updated: May 16, 2003 18:56 IST
In the upper reaches of the Indo Gangetic plains, one of the traditional harvesting systems is the johad, which is basically a series of tanks connected to each other by nullas or channels. These channels could be on the surface or below it. Good examples are found in Kandhla in Muzaffarnagar in UP.
Azamgarh district has this feature extensively used for irrigation. It is an embankment usually long and straight thrown across a plain where rice was cultivated in an area or surplus flow of water.
