Question: Which aspects of forming practice were regulated in the context of Hiware Bazar to improve the water conservation? (Conceptual Understanding)
Answer: Hiware Bazar village was selected under the Adarsh Gram Yojana of Maharashtra Government. Some of the aspects they regulated to improve the water conservation.
Continuous Contor Trenches (CCT) were dug on the hill slopes to arrest the erosion of soil, water harvesting, and encourage the growth of grass.
A number of water harvesting structures were also built in the village check dams, percolation tanks, and loose boulder structure.
The soil and water conservation work in Hiware bazar were implemented on common land and private land.
Challenges:
1) Tungabhadra dam has gradually lost its water storage capacity over the decades with accumulation of silt due to mining, dust, soil erosion, debris etc.
