The State authorities is selling development of recent era verify dams throughout pure streams, rivulets and different waterbodies below the MGNREGA programme. Over 5,000 a number of arch buttress verify dams (MACD) have come up below MGNREGA, 1,820 within the final two years.
The challenge is exclusive as a result of the design consumes much less concrete and lasts longer than conventional stone masonry verify dams. The price of MACD is round 25% lower than Strengthened Cement Concrete verify dams. They harvest rain water, act as short-term impounding constructions, and recharge the aquifer. Aside from offering water to farmers in drier months, they act as water holes for wildlife too.
Aniruddha Shravan, commissioner, MGNREGA, mentioned MACDs guarantee higher utilisation of funds, scientific development, and elevated effectivity in water harvesting. “We use the companies of Karnataka State Distant Sensing Software Centre to map possible places for verify dams to stop unscientific development. We now have been utilizing an app designed by the Basis for Ecological Safety known as CLART to find dams close to acceptable strata. We select a web site the place the stream is at its narrowest width, because it reduces prices and to see that the stream shouldn’t be meandering as it could actually trigger flooding and shifting of the river’s course,” he mentioned. He added that gram panchayats are creating boulder checks with recharge pits in massive numbers. “To keep away from slush getting collected in downstream verify dams, a number of water harvesting constructions are constructed upstream,” added Mr. Shravan. They maintain again silt, enhance soul moisture, help vegetative progress, and harvest the rain extra successfully.
“MACDs have introduced long-lasting change in districts like Vijayapura, Bagalkot and the drier taluks of Belagavi,” mentioned Mahantesh Biradar, Vijayapura-based environmentalist. In a number of villages in Vijayapura district, floor water ranges have elevated and girls are relieved of the burden of strolling for miles to fetch consuming water, he added.
The MACD mannequin was launched by the Bidar Zilla panchayat in 2004. Naveen Raj Singh, a civil engineer by coaching, was the ZP CEO then. He launched the design and led the development of round 100 such constructions in two years. Now, Bidar has over 700 MACDs. The design was accepted for MNREGA in 2015, Mr. Singh recalled.
