CUET UG Geography Booster Test 2-Indira Gandhi Canal Project

According to the explicit terms of the provided passage, the introduction of unmanaged water practices into an arid environment has caused unintended ecological damage. The text states: "But the intensive irrigation and excessive use of water has led to the emergence of twin environmental problems of waterlogging and soil salinity." When excessive amounts of surface water are applied to desert soils with poor natural drainage, the excess water cannot drain away. Instead, it accumulates and causes the local water table to rise to the root zone, creating waterlogging. This direct cause-and-effect relationship confirms option C.

Soil salinity is an environmental challenge caused by high evaporation rates in arid regions. When fields are over-watered, the rising water table carries dissolved underground salts to the surface. As the water evaporates in the desert heat, it leaves behind a thick crust of white salt. This salt accumulation stunts crop growth and can make fertile land completely barren. By destroying the soil base, salinity directly threatens long-term agricultural production, making option B the correct answer.

Statement I is correct because Kanwar Sain, a visionary hydraulic engineer from Rajasthan, conceived the project. He drafted a foundational report proposing that surplus water from Himalayan rivers be used to irrigate the Thar Desert. Statement II is incorrect because he submitted this conceptual design in 1948, a decade before the project was launched on 31 March 1958. An engineering plan must be finalized before construction can begin. Therefore, Statement I is true and Statement II is false, validating option A.

When the large-scale infrastructure project was launched in 1958, it was named the Rajasthan Canal. This name reflected its main purpose: transporting water from Punjab rivers to irrigate the arid plains of western Rajasthan. In November 1984, the government renamed the network the Indira Gandhi Canal to honor the late Prime Minister following her assassination. This historical naming progression makes option C the correct answer.

This question requires organizing the geographical steps of the canal's water flow from source to destination. The water path starts at the Harike Barrage in Punjab, located at the confluence of the Sutlej and Beas rivers (1). From this intake point, the main canal flows southwest into Rajasthan, running parallel to the international border with Pakistan at an average distance of 40 kilometers (2). Finally, the water flows into a network of branch channels to irrigate the arid Thar Desert (Marusthali) in western Rajasthan (3). This geographic progression yields the sequence 1, 2, 3, validating option B.

The total culturable command area of 19.63 lakh hectares is divided into two types of irrigation channels based on regional topography. The gravity-fed flow system handles 70 percent of the area, serving the flat plains on the west bank where water moves naturally down the slope. The remaining portion of the command area must rely on mechanical lift channels to pump water uphill along the east bank. Subtracting the flow system's 70 percent share from the total area leaves a 30 percent share for the lift system 100% − 70% = 30%), confirming option B.

Statement I is correct because all gravity-fed flow channels originate on the right bank of the main canal. Statement II is correct because the land on the right bank slopes gently downward toward the Indus River valley. This natural terrain allows water to flow through branch channels and into fields by gravity alone. Because the water moves downhill with the slope, these channels do not require expensive mechanical pumping stations. Since both statements are factually accurate, option C is the correct answer.

This matching question relates different canal features to their topographical characteristics. Flow channels (1) utilise the natural slope of the land (A), allowing water to move by gravity without pumping. Lift channels (2) operate against the natural slope of the land using pumps (B) to deliver water to higher areas. Gravity irrigation (3) involves water flowing naturally without mechanical pumping (C). Lift irrigation (4) depends on mechanical devices to raise water to higher elevations (D). Therefore, the correct matching is 1-A, 2-B, 3-C, 4-D.

Turning dry desert land into vegetated fields required more than just building the main canal channel. To distribute water efficiently, the government launched the Command Area Development (CAD) program. The CAD framework managed local engineering work, lined delivery channels to prevent leaks, and oversaw extensive tree and pasture planting projects. These integrated planting programs stabilized loose sand dunes and led directly to the greening of the desert landscape, validating option B.

Statement I is correct because planting tree lines and pastures creates a root network that anchors loose sand dunes. This plant cover greens the landscape and acts as a physical windbreak. Statement II is correct because blocking desert winds prevents them from carrying loose sand into nearby canal channels. By stopping sand from blowing into the water, these planting programs protect the canal infrastructure from siltation. Since both statements are part of this environmental chain, option C is the correct answer.

Before the canal network was built, a lack of water limited desert farmers to growing a single crop during the short rainy season. The introduction of a reliable, year-round canal supply changed regional agriculture. With steady access to water, farmers could cultivate their fields across multiple seasons each year, switching from single-crop farming to multi-crop farming. In agricultural geography, this increased land use over the year is described as an increase in the intensity of cropping, validating option A.

This matching question relates different crop categories with their corresponding examples in the Indira Gandhi Canal Command Area. Traditional crops grown under limited soil moisture (1) include gram, bajra and jowar (A) because these crops can withstand dry conditions. New crops introduced through intensive irrigation (2) include wheat, cotton, groundnut and rice (B), which require a reliable water supply. Cash crops (3) are represented by cotton and groundnut (C) because they are mainly cultivated for commercial purposes. Food grains under irrigated agriculture (4) include wheat and rice (D), which became widely cultivated after irrigation facilities expanded. Therefore, the correct matching is 1-A, 2-B, 3-C, 4-D.

The timeline of the infrastructure project shows how construction moved from north to south. Following the launch of construction in March 1958, engineers focused early work on Stage-I in northern Rajasthan, which covers Ganganagar and Hanumangarh. These early delivery channels were completed in the early 1960s. Water officially began flowing into Stage-I fields during the 1960s, kicking off the region's agricultural shift and validating option B.

This question tests knowledge of the climatic characteristics of the Stage-II command area of the Indira Gandhi Canal Project. The region comprises desert land with shifting sand dunes and experiences very high summer temperatures. The maximum summer temperature mentioned for this area is 50ºC, reflecting the harsh conditions of the deeper Thar Desert. Therefore, option C is correct.

This question requires organizing sustainable development guidelines in their logical order of priority, moving from high-level policy to field rules and then to environmental cleanup. The framework starts with high-level policy, requiring the strict implementation of a water management policy to restrict water-intensive crops (1). Next, it applies this policy on the ground using specific delivery controls, such as the timed Warabandi rotation system, to cut water losses (2). Finally, it addresses existing environmental damage by reclaiming fields already ruined by waterlogging and soil salinity (3). This logical progression yields the sequence 1, 2, 3, validating option D.

The irrigation project was implemented in different stages with specific objectives. Stage-I (1–d) adopted protective irrigation, where water is distributed over a larger area to minimise crop losses during drought. Stage-II (2–b) focused on extensive irrigation of crops and pasture development, particularly in arid regions. Command Area Development (3–c) involves improving field channels, drainage systems and efficient water distribution within the irrigated area. Protective Irrigation (4–a) refers to an irrigation policy that aims to protect crops by providing limited but widespread water supply. Therefore, the correct matching is 1–d, 2–b, 3–c and 4–a, making Option C the correct answer.

Statement I is correct because sustainable development guidelines state that farmers should avoid water-intensive crops like rice or sugarcane. Instead, the policy encourages planting fruit trees, such as citrus fruits, which require less water and protect the soil from salinity. Statement II is correct because Stage-II runs through an arid environment shaped by shifting sand dunes. Establishing pastures in this area is essential to anchor loose sand and restore environmental balance. Since both statements are part of the region's eco-development strategy, option C is the correct answer.

Reviewing the canal's history shows a clear conflict between short-term agricultural gains and long-term environmental damage. Decades of intensive irrigation have caused serious issues like waterlogging and soil salinity, which ruin fertile land. To protect the region's future, planners and scholars emphasize that long-term economic development is impossible without first fixing the environment. This means development plans must focus heavily on ecological sustainability, validating option A.

Social sustainability requires ensuring that all social groups share in the benefits of a development project, preventing wealthy landowners from controlling all the gains. In this canal command area, poor and landless settlers received land plots but often lacked the capital needed to start farming. Without money for seeds, tools, or land clearing, they could not use their allotments. Providing these settlers with financial loans and farming tools allows them to cultivate their fields, build a secure livelihood, and achieve social sustainability, validating option B.

Relying entirely on crop farming leaves a regional economy vulnerable to crop failures, market price shifts, or environmental issues like soil salinity. To build long-term economic stability, the regional economy must look beyond cultivation to develop related sectors, including livestock rearing, dairy farming, agro-processing, and local trade hubs. In economic planning, this process of broadening and balancing the local economy across multiple sectors is described as the diversification of the economic base, validating option B.
