khadins and johads are built in which parts of india
Johad A johad (Hindi: जोहड) is a community owned rainwater storage tank wetland principally used in the state of Harayana and Rajasthan of 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. Some johads also have bricked or stones masonry and cemented ghat (series of steps and/or ramp). 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 purpose. Johads are often seen surrounded by embankment, with water well and trees around them. In many parts of the state, 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. Smaller cemented water tanks called tanki or tanka in parts of Rajasthan are also sometimes mistakenly referred to as johad. 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.[1][2]
Gates of Delhi Shahjahanabad, the seventh city of Delhi, was built by Shah Jahan in 1649 like a fortress encircled by strong and high red–brick walls with 14 entry gates to the city, in addition to 16 wicket gates called windows (khirkis in Urdu language). A number of bastions built of stone were added by the British, in addition to repairing the earlier fort, to make the fort more secure. The gates were designed and built for the people to have access and the royal procession to enter or exit, when going out in diverse directions. Out of the 14 gates, five gates have survived, namely, the Kashmiri Gate on the north, the Ajmeri Gate on the south-west, the Delhi Gate on the south-east, Turkman Gate on the south and the Nigambodh Gate on the north-east, all of which express vividly the splendor of the city. All the gates are located within a radius of 5–6 km (3.1–3.7 mi) in the present day Old Delhi. The Lahori gate on the Northeast, in the old city, was demolished (some remnant walls are seen at the crossing as may be seen in picture) and the area converted into the present day Lahori Bazar. The gates have a square plan with high arched openings, except for low height of the Nigambodh gate, and two openings—one for entry and another for exit—of the Kashmiri gate.[9] The names of all the gates, which existed during Shahajahan’s time are the Dilli Darwaza (also known as Delhi Gate), Kabuli Darwaza, Raj Ghat Darwaza, Khizri Darwaza, Nigambodh Darwaza, Kela ke Ghat ka Darwaza, Lal Darwaza, Kashmiri Darwaza, Badar Darwaza, Patthar Khati Darwaza, Lahori Darwaza, Ajmeri Darwaza and Turkuman Darwaza.
