CUET UG Geography Booster Test 1-Indira Gandhi Canal Project

This question requires direct retrieval of information from the provided passage. The text explicitly outlines the physical differences between the two construction stages. The third sentence states: "The command area of Stage-I... has a gently undulating topography and its culturable command area is 5.53 lakh hectares." This type of terrain features smooth, rolling hills that are well-suited for building gravity-fed flow networks, confirming that option B is the correct answer.

This question requires cross-checking the regional boundaries of the two construction stages using the text. The passage states that the command area of Stage-I lies in Ganganagar, Hanumangarh, and northern Bikaner. It then lists the districts for Stage-II: Bikaner, Jaisalmer, Barmer, Jodhpur, Nagaur, and Churu. Jaisalmer belongs exclusively to Stage-II, as it lies in the deeper western desert area and was added during the later expansion phase, validating option C.

This question requires identifying the year the canal project was first planned. Chief Engineer Kanwar Sain submitted a report to the government titled "Requirement of Water for the State of Rajasthan" in 1948. This report marks the formal beginning of the project's planning phase, long before construction began. This verified date confirms that option B is the correct choice.

Statement I is correct because construction began on 31 March 1958, starting work on the feeder network in Punjab. Statement II is correct because the project was originally named the Rajasthan Canal. The government renamed it the Indira Gandhi Canal in November 1984 to honor the late Prime Minister. Since both statements are factually accurate, option D is the correct answer.

The main alignment of the canal was chosen to irrigate the highly arid Thar Desert (Marusthali) in western Rajasthan. The canal flows southwest through this region, running parallel to India's international border with Pakistan. It maintains an average distance of 40 kilometers from the border line, providing water to districts like Jaisalmer and Barmer. This geographical path makes option C the correct answer.

The Indira Gandhi Canal Project uses two major irrigation systems based on the terrain. The Flow System (1–a) distributes water through gravity without the need for pumping, making it suitable for gently sloping areas. The Lift System (2–b) covers the remaining 30% of the command area, where water must be pumped to higher elevations. The West Bank Canal System (3–c) irrigates approximately 70% of the command area through the gravity-fed flow system. The East Bank Canal System (4–d) serves elevated regions where water is lifted using pumps. Therefore, the correct matching is 1–a, 2–b, 3–c and 4–d, making Option B the correct answer.

This question requires organizing the canal's structural components from left to right when looking down the stream (from north to south). Looking downstream, the left side corresponds to the east bank and the right side to the west bank. Because the land on the east bank slopes upward, the lift canals originate on the left side of the main channel (3). The main canal flows through the center of the system (2). The land on the west bank slopes downward, so the gravity-fed flow channels originate on the right side (1). This left-to-right arrangement yields the sequence 3, 2, 1, validating option A.

The location of the lift canals is determined by the region's topography. The main canal flows from north to south, making its left bank the eastern side. The land on this eastern side slopes upward, rising away from the water channel. Because gravity cannot move water up these slopes, all lift canals are built on the left bank. These channels use mechanical pumps to lift water uphill so it can irrigate eastern fields, validating option B.

Introducing canal water changed the arid environment of the Thar Desert. Before the canal was built, the dry soil limited plant growth. The reliable supply of canal irrigation provides long-term moisture to the soil, which supports cultivation, afforestation, and pasture programs. This transformation turned dry sand dunes into vegetated fields, a change described as the greening of the land, validating option B.

Statement I is correct because planting trees and pastures creates a root network that anchors loose sand dunes and forms a barrier against desert winds. This vegetative cover reduces wind erosion across the region. Statement II is correct because anchoring the sand dunes prevents desert winds from blowing loose sand into nearby canal channels. This reduction in blowing sand prevents siltation, keeping the water channels clear. Since both statements are correct, option C is the correct answer.

While intensive irrigation increased early crop yields, over-watering has caused long-term environmental issues. Poor drainage in the desert soil has created waterlogging, while high evaporation rates leave behind capillary salts that cause soil salinity. Waterlogged soils suffocate plant roots, and surface salt crusts make the land infertile. This environmental damage undermines the long-term sustainability of farming in the region, validating option B.

Different environmental management practices produce different outcomes in irrigated regions. Intensive irrigation and excessive use of water (1–a) can lead to soil salinity and waterlogging, especially in arid areas where evaporation leaves salts on the soil surface. Afforestation and pasture development (2–b) help reduce wind erosion and stabilise sand dunes by increasing vegetation cover. Lining of irrigation canals (3–c) reduces water loss through seepage and improves irrigation efficiency. Shelterbelt plantation (4–d) protects agricultural fields from strong winds, reducing soil erosion and creating favourable conditions for cultivation. Therefore, the correct matching is 1–a, 2–b, 3–c and 4–d, making Option C the correct answer.

Statement I is correct because providing water to dry lands allowed farmers to expand their cultivated fields into areas that were once too dry to farm. Statement II is correct because a reliable, year-round water supply allowed farmers to grow multiple crops on the same field each year, increasing cropping intensity. Statement III is incorrect because introducing canal water caused an immediate jump in both farming and livestock yields rather than a decrease. Therefore, Statements I and II are correct, validating option A.

This question requires arranging the region's historical cropping patterns in chronological order to show how irrigation changed agriculture. Before the canal was built, the dry environment restricted farmers to rainfed agriculture. They grew drought-resistant coarse grains like gram, bajra, and jowar (2). Introducing reliable canal irrigation changed local farming. With a steady water supply, farmers switched to high-yield, water-intensive cash crops like wheat, cotton, groundnut, and rice (1). This historical sequence yields 2 followed by 1, validating option B.

Conveyance losses happen when water leaks into the ground or evaporates while moving through open delivery channels. To address this issue, sustainable development guidelines require implementing the Warabandi system. Warabandi is a water management framework that enforces timed water rotations among farmers. This structured schedule prevents over-watering, reduces delivery losses, and ensures water is distributed fairly down the canal line, validating option B.

To address environmental issues like waterlogging and soil salinity, sustainable development guidelines include restrictions on crop choices. Because over-watering causes water tables to rise and leads to salt crusts, the policy states that the regional crop mix should not include water-intensive crops like rice or sugarcane. Instead, the policy encourages growing citrus fruits, pastures, and crops that require less water to protect the soil, validating option C.

Stage-II runs through an arid desert environment shaped by shifting sand dunes and high summer temperatures. To protect this fragile terrain, sustainability guidelines require a comprehensive planting program. This program includes afforestation to restore plant cover (I), shelterbelt plantations along canals and roads to block desert winds (II), and pasture development to anchor loose sand dunes (III). Because all three measures are essential for environmental restoration in Stage-II, option D is the correct answer.

The planning framework outlines seven specific measures to promote sustainable development in the canal command area. To address environmental issues like soil salinity and waterlogging, five of these seven measures focus directly on environmental restoration and water conservation. These include water management policies, lining delivery channels, implementing the Warabandi system, afforestation, and pasture development. The remaining two measures focus on social equity and economic diversification, confirming that option C is the correct choice.

This question requires arranging the steps for supporting poor settlers in a logical order. The process begins when the state distributes land plots to landless and economically disadvantaged settlers (3). Because these settlers often lack capital, the project cannot succeed on land distribution alone. The government must provide financial loans and institutional tools to help them buy seeds and equipment (2). With this financial support in place, the settlers can clear sand dunes and begin effective cultivation of their land (1). This logical progression yields 3, 2, 1, validating option A.

Sustainable development requires balancing environmental, economic and social objectives. Ecological sustainability (1–a) focuses on reclaiming areas affected by waterlogging and soil salinity to restore environmental quality. Economic sustainability (2–b) is achieved through diversification of the economic base by promoting allied activities such as animal husbandry, dairy farming and agro-based industries. Water resource sustainability (3–c) emphasises efficient irrigation methods and water conservation to ensure long-term availability of water resources. Social sustainability (4–d) aims at improving people's participation, livelihoods and overall quality of life through community development. Therefore, the correct matching is 1–a, 2–b, 3–c and 4–d, making Option B the correct answer.
