Explanations:The Indira Gandhi Canal, also known as the Rajasthan Canal, is a significant water distribution system in the state of Rajasthan, India. It is the world's longest canal, stretching over 650 kilometers. The primary purpose of this canal is to provide irrigation to the arid and semi-arid regions of northwestern Rajasthan, which are characterized by low rainfall and high evaporation rates.
The canal was constructed to address the severe water scarcity in these regions, which are predominantly agricultural areas. The canal's water supply is crucial for sustaining agricultural activities and supporting the livelihoods of the local population. The canal originates from the Harike Barrage on the Sutlej River in Punjab and extends into Rajasthan, passing through several districts.
Among the districts served by the Indira Gandhi Canal, Ganganagar and Bikaner are the primary beneficiaries. Ganganagar, located in the northern part of Rajasthan, is one of the driest districts in the state and heavily relies on the canal for irrigation. Similarly, Bikaner, situated in the western part of Rajasthan, is another arid district that benefits significantly from the canal's water supply.
The canal's construction and operation have had a profound impact on the agricultural productivity and economic development of these regions. It has enabled farmers to cultivate crops that were previously impossible to grow due to the lack of water. The canal's water is used for irrigation of various crops, including wheat, cotton, and sugarcane, which are essential for the local economy.
Understanding the geographical distribution and the primary service areas of the Indira Gandhi Canal is crucial for students preparing for competitive examinations, particularly those focusing on general knowledge and geography. The canal's role in providing water to Ganganagar and Bikaner districts highlights the importance of large-scale water distribution systems in addressing water scarcity and supporting agricultural activities in arid regions.
