Question

Traditional harvesting system is a useful system to conserve and store water. ‘Highlight the importance of this system with two examples.

Answer 1

Hint:
Conservation of water generally refers to protect, preserve, and regulate the usage of water and its resources. It is the system introduced to organize freshwater, reduce wastage and protect the water and its reserves to decrease and to avoid scarcity. Therefore, we all should come forward to develop awareness about conservation of water among our friends, family, neighbours, society, etc. Rainwater harvesting is one of the methods of conservation of water.

Complete solution:
Rainwater harvesting is the simple technique or method used to preserve Rainwater by collecting, storing, conveying and purifying Rainwater that runs off from rooftops, gardens, roads, empty grounds, etc. for later use.

Water has been conserved in India since the ancientness, with our ancestors improving the skill of water management. Many water harvesting layouts and water conveyance systems certain to the eco-regions and culture have been developed. They collected the raindrops directly. From rooftops, they acquired water and stored it in tanks built in their courtyards. From open community lands, they collected the rain and collected it in artificial wells. They harvested monsoon runoff by capturing water from swollen streams during the monsoon season and reserved it for various structures of water bodies.

Some traditional techniques include:

Paar system:
Paar is a traditional water harvesting method in the western Rajasthan region. It is a commonplace where the rainwater flows from the agar (catchment) and in the process percolates into the sandy soil. To permit the Rajani pani (percolated water), kuis or berries are dug in the agor (storage area). Kuis or berries are commonly 5 metres (m) to 12 m deep. The pattern was designed through traditional masonry technology.

 Talab / Bandhis:
Talabs are reservoirs. They may be biological, such as the ponds (pokhariya) at Tikamgarh in the Bundelkhand region. They can be man-made, such as the lakes in Udaipur. A reservoir area of fewer than five bighas is called a tale; a medium-sized lake is called a band or talab; bigger lakes are called Sagar or sand.

Johads:
Johads are small earthen check dams that capture and conserve rainwater, enhancing percolation and groundwater recharge. Starting 1984, the last sixteen years have seen the revival of some 3000 johads dispersed across more than 650 villages in Alwar district, Rajasthan.
The method by which rainwater is collected and reserved either to restore the groundwater or for use in the future is known as rainwater harvesting. The technique or setup used for rainwater harvesting is known as rainwater harvesting system.
The rainwater on the canopies of the houses is collected through canals that drip the water into ground reservoirs. This stored water is later used. They restore the groundwater. They can be utilized for drinking and another domestic purpose. Water can be used throughout the year. Decrease stormwater discharges, urban floods and overloading of sewage treatment plants. Decrease seawater ingress in seaside areas. They act as water for irrigation.

Note:
 Zings are water collecting structures found in Ladakh. They are little tanks, in which they gather dissolved ice sheet water. Basic to the framework is the organization of directing channels that carry the water from the icy mass to the tank. As icy masses dissolve during the day, the channels top off with a stream that in the early evening transforms into streaming water. The water gathers towards the night and is utilized on the next day.
