The Indira Gandhi Canal, which has been providing irrigation to the Thar Desert since 1958, was designed to turn barren, sandy land into fertile agricultural areas. Originally named the Rajasthan Canal, it was renamed in 1984 after Prime Minister Indira Gandhi, who was assassinated that year. The project was first proposed in 1948 by engineer Kanwar Sain, and construction began in 1958. The canal stretches from the Harike barrage, located at the meeting point of the Sutlej and Beas rivers in Punjab, to irrigation sites in northwest Rajasthan. Its purpose was to provide a reliable water supply to drought-prone areas, converting arid land into cultivable fields and offering an alternative to the region’s scarce and often saline groundwater. However, the project has had unintended environmental consequences. The lack of an adequate drainage system led to a rise in the groundwater table, causing soil to become oversaturated and increasing the salinity of the land. Studies show that the depth of irrigation water has reached about one meter, nearly double the original target for the project’s first phase. This has turned areas like Dabli Kalan, Dabli Khurd, Masitawali Head, and Lunio ki Dhani into swampy regions with visible signs of salt buildup on the surface. Despite decades of investment, agricultural yields have dropped by as much as 40% in some areas. The water intended to combat desertification has, in some cases, led to long-term flooding and harmful conditions for crops. The cultivation of water-intensive cash crops has worsened the problem, creating a cycle where more irrigation raises the water table and increases salt levels. To address this, local authorities have introduced measures such as bio-drainage using plants like Salvadora, Tamarix, Eucalyptus, and Prosopis juliflora. Additionally, modernization efforts including canal relining, cleaning campaigns, and the expansion of drainage networks are ongoing, aimed at reducing saturation and salinity in the oldest affected areas. The Indira Gandhi Canal still provides drinking water to villages where natural groundwater is too salty for consumption. While the project has not been a complete failure, it is also not without flaws. It has sustained some agricultural areas while others have been negatively impacted, tehsil by tehsil, in regions like Tibbi and Rawatsar. The canal stands as a complex example of development that has brought both benefits and challenges to the region.
