A johad ({{Lang-hi|जोहड}}) is a community-owned traditional harvested rainwater storage wetland principally used for effectively harnessing water resources in the state of Harayana, Rajasthan, Punjab, western Uttar Pradesh of North India, that collects and stores water throughout the year, to be used for the purpose of recharging the groundwater in the nearby water wells, washing, bathing and drinking by humans and cattle.[1][2][3][4] Some johads also have bricked or stones masonry and cemented ghat (series of steps and/or ramp).[1][2][4] Johads also cater to resident and seasonal migrant birds as well as wildlife from the nearby bani (forest). State fisheries departments also promote the use of these johads for raising fishes on contract basis for commercial fishing. Johads are often seen surrounded by embankment, with water well and trees around them. In many parts, specially in dry state of Rajasthan, the annual rainfall is very low (between 450 and 600 mm) and the water can be unpleasant to drink. Rainfall during July and August is stored in johads and used throughout the year. Johad in Haryanvi language and Rajasthani language are also called sarovar, taal and talab in Hindi language, and water pond or lake in English. Johads are called as khadin in Jaisalmer district. Over 4,500 working johads in Alwar district and surrounding districts Rajasthan were revived by the NGO Tarun Bharat Sangh by Rajendra Singh. Haryana formed the Haryana State Waterbody Management Board to rejuvenate and manage 14,000 ponds in the state, including the development of 60 lakes in Delhi NCR falling within the state.[8][9] Smaller cemented water tanks called tanki or tanka in parts of Rajasthan are also sometimes mistakenly referred to as johad. Concretised rain-fed tanka and canal-fed diggi are different from the johads. Johad wetlandsConstructionJohads can be of several types, such as dug out in areas to which rainwater can be easily channeled. Alternatively, simple mud and rubble barrier check dams may be built across the contour of a slope with a high embankment on the three sides while the fourth side is left open for the rainwater to enter. These catch and conserve rainwater, leading to improved percolation and groundwater recharge. They are very common in most villages of states of Haryana, Rajasthan, Uttar Pradesh and the Thar desert of Rajasthan in India.[1][2][3][4] Haryana Johads rejuvenationIn 2007, Haryana Irrigation Department spent INR435.26 crore (INR4.3 billion or US$7 million) to renovate and restore water bodies in the state for the conservation of water, recharging of ground water, preservation of environment and enhancement of tourism.[5] A study by the Panjab University found 60 fish species of 19 families, 11 commercial and 6 exotic species, in the water bodies of Haryana.[6] Water bodies remain under risk from encroachment, shrinking of catchment area and pollution.[7] In 2010, India's first ever diatom data basing was done in ten different water bodies at ten different stations in Haryana.[8] A 2015 study of 24 water bodies of Haryana, found 39 morphologically different types of diatoms.[9] In 2016, the Government of Haryana announced a plan to map the district-wise map of water flow and to create a database of all water bodies within the state.[10] These water bodies have contributed to the economic development through fisheries in the landlocked state of Haryana. Haryana ranks second in India in terms of the average annual fish production per unit area in the country with 7000 kg per hectare average annual fish production.[11] Fish production has increased from 600 tonnes in 1966-67 at the time of formation of Haryana to 121000 tonnes of fish during the year 2015-16, providing a livelihood to over 30000 families in fisheries sector.[12] 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.[13][14] Rajasthan Johads rejuvenationThere 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.[15][16] 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 bodiesFollowing are similar to the Johads but are still distinct types of water bodies with specific differentiating features. TankaTanka or Tanki is a rain-fed water storage in the arid areas of the Indian subcontinent, such as Rajasthan, specially in the bagar tract. DiggiDiggi is a canal-fed water works for rural drinking water supply.[17] It is usually a purpose-dug open pond, smaller than the typical johad, often concretised to prevent the water loss.
