India also relies excessively on groundwater resources, which accounts for over 50 percent of the irrigated area with 20 million tube wells installed. India has built nearly 5,000 major or medium dams, barrages, etc. to store the river waters and enhance groundwater recharging. [ 15 ]
Employing almost 44% of India's working population, agriculture is one of the most important occupations in India. Consequently, up to 80% of the groundwater in India is used for irrigation. [37] The Indian Agriculture Institute has been promoting the drip irrigation technology to relieve the water scarcity in India for decades. The technology ...
Irrigation in India includes a network of major and minor canals from Indian rivers, groundwater well based systems, tanks, and other rainwater harvesting projects for agricultural activities. Of these groundwater system is the largest. [ 1 ]
Map of India based on survey of rivers of India.. The Indian rivers interlinking project is a proposed large-scale civil engineering project that aims to effectively manage water resources in India by linking rivers using a network of reservoirs and canals to enhance irrigation and groundwater recharge and reduce persistent floods in some parts and water shortages in other parts of the country.
Out of all the water on Earth, saline water in oceans, seas and saline groundwater make up about 97% of it. Only 2.5–2.75% is fresh water, including 1.75–2% frozen in glaciers, ice and snow, 0.5–0.75% as fresh groundwater and soil moisture, and less than 0.01% of it as surface water in lakes, swamps and rivers.
This page shows the state-wise list of dams and reservoirs in India. [ 1 ] [ 2 ] As of July, 2019, total number of large dams in India is 5,334. [ 3 ] About 447 large dams are under construction in India . [ 4 ]
Of the total irrigated area worldwide 38% is equipped for irrigation with groundwater, especially in India (39 million ha), China (19 million ha) and the United States of America (17 million ha). [9] Total consumptive groundwater use for irrigation is estimated as 545 km 3 /year.
India accounts for 18% of the world population and about 4% of the world’s water resources. One of the solutions to solve the country’s water woes is to create Indian Rivers Inter-link.c [2] India has been successful in creating live water storage capacity of about 253 billion cubic meter(BCM) so far.
