Explanation: The Indira Gandhi Canal, also known as the Rajasthan Canal, is a major irrigation canal in Rajasthan, India. It is the largest canal in India and has significantly contributed to the green revolution in the state by providing water for irrigation in the arid regions of northwestern Rajasthan. The canal was named after Indira Gandhi, the former Prime Minister of India, who laid the foundation stone for the project in 1958.
The Indira Gandhi Canal is a part of the Indira Gandhi Nahar Project (IGNP), which was initiated to provide irrigation facilities to the arid and semi-arid regions of Rajasthan. The canal originates from the Harike Barrage on the Sutlej River in Punjab and extends over a length of about 650 kilometers. It passes through the districts of Bikaner, Churu, and Hanumangarh, providing water to over 1.5 million hectares of land.
The construction of the canal began in 1966 and was completed in 1987. The project has transformed the desert landscape into fertile agricultural land, enabling farmers to cultivate crops such as wheat, cotton, and vegetables. The canal has not only improved agricultural productivity but has also contributed to the socio-economic development of the region by providing employment opportunities and improving the standard of living.
The Indira Gandhi Canal has been instrumental in bringing about greenery in Rajasthan, which was previously a barren and arid region. The canal has played a crucial role in the green revolution in Rajasthan, making it possible for farmers to cultivate crops in areas that were previously unsuitable for agriculture due to the lack of water. The canal has also helped in the recharging of groundwater, which has further contributed to the sustainability of agriculture in the region.
In conclusion, the Indira Gandhi Canal is the correct answer as it has significantly contributed to the green revolution in Rajasthan by providing water for irrigation in the arid regions of the state. The canal has transformed the desert landscape into fertile agricultural land, improving the socio-economic conditions of the region.
