sector. On 1 November 2017, Chief Minister of Haryana Manohar Lal Khattar announced that Government of Haryana will form the Haryana State Waterbody Management Board to rejuvenate and manage 14,000 ponds in Haryana by digging the silt out every year. This includes development of 50 to 60 lakes in National Capital Region falling within the Haryana state. As of 2020, Government of Haryana is reviving various johads of Gurugram. In June 2020, for the revival of pond at Gwal Pahari, the estimates were being prepared to undertake erection of boundary wall, building a walking track around the johad, clearing of bushes and planting of trees and to connect the seasonal rivulet to the johad to ensure it retains water year around. In 2021, Haryana will undertake a survey based on 1957 revenue records and satellite survey to identify the ponds, remove encroachments and among those in first phase rejuvenate 1868 ponds by the end of 2022 to use water from pond to irrigate 50 acre land per pond or targeted irrigation of total 93400 land from the rejuvenated ponds. Rajasthan Johads rejuvenation There was a severe drought in Alwar district in Rajasthan during 1985-86. In 1985, volunteers from the Tarun Bharat Sangh (TBS), a voluntary organization led by Rajendra Singh, came to Alwar. The Alwar District had once thrived, but logging, mining, and other industrial activities resulted in land degradation that intensified flooding and droughts. The traditional water management system using johads was abandoned. TBS revived the tradition of building johads, an example of traditional technology that provided water for use and recharging ground water. Now smaller cemented johads are popularly known as tankas in most parts of the arid state of Rajasthan. The water revolution spread by tanki and johads in the Alwar district has spread far and wide. Now there are around 5,000 johads all over Rajasthan and this has greatly helped in reducing water shortage and improving water quality. Similar water bodies Following are similar to the johads but are still distinct types of water bodies with specific differentiating features. Tanka Taanka or Tanki is a rain-fed water storage in the arid areas of the Indian subcontinent, such as Rajasthan, specially in the bagar tract. Diggi Diggi is a canal-fed water works for rural drinking water supply. It is usually a purpose-dug open pond, smaller than the typical johad, often concretised to prevent the water loss. See
