CUET UG Geography Booster Test 2-Management and Conservation

Statement I is incorrect because a demographic transition is driven by changes in birth and death rates over time, which are influenced by a wide range of medical, social, and economic factors rather than being solely caused by water management issues. Statement II is correct because freshwater is a shared resource that crosses political boundaries. As supplies shrink and demand rises from growing populations and industries, control over water channels and aquifers leads to legal, political, and social conflicts. This makes the allocation of water resources a highly contested issue among local communities and neighboring states. Therefore, only Statement II is true, validating Option B.

The Environment Protection Act, 1986 provided an umbrella legal framework for environmental protection, but ineffective implementation resulted in 251 polluting industries continuing along river banks by 1997, making 1-A correct. The National Water Policy, 2012 introduced modern principles such as water footprints and recognized water as an economic good, making 2-B correct. The Water (Prevention and Control of Pollution) Act, 1974 established the institutional and legal framework for preventing and controlling water pollution, making 3-C correct. The Water Cess Act, 1977 imposed a cess on industrial water consumption to generate funds for pollution control boards, making 4-D correct. Therefore, the correct matching is 1-A, 2-B, 3-C, 4-D, i.e., Option A.

Statement I is true because the Pradhan Mantri Krishi Sinchayee Yojana (PMKSY) aims to improve water use efficiency on farms through sustainable methods like drip and sprinkler irrigation. Statement II is false because the program uses a planned watershed approach to restore and develop rain-fed farming areas. It does not advocate for unchecked groundwater pumping, which lowers water tables and depletes regional aquifers. Instead, the policy focuses on balanced replenishment and careful use, meaning only Statement I is correct and validating Option A.

The Jal Kranti Abhiyan (2015-16) is a national campaign designed to turn water conservation into a widespread public movement. A key part of this initiative involves selecting and developing pilot locations to demonstrate sustainable water management. The policy specifies creating a model command area of approximately 1,000 hectares to show how integrated water use, modern irrigation, and waste reduction can work on a larger scale. This target is explicitly stated as 1,000 hectares in the text, validating Option B.

Central Pollution Control Board monitoring shows that river water quality changes with the seasons. During the dry summer months, river flows drop significantly due to high evaporation and a lack of rainfall. When water levels are low, rivers lose much of their natural capacity to dilute incoming chemicals and urban waste. As a result, pollutant concentrations rise sharply. Recycling industrial water reduces the need to draw fresh water and prevents the discharge of concentrated effluents during these vulnerable low-flow periods, validating Option B.

An urban water cascade uses water in stages based on quality to maximize conservation. The process starts by directing clean, treated municipal water to households for tasks that require high-purity water, such as drinking, cooking, and bathing (1). Second, the resulting graywater from showers and washing machines is collected through separate household plumbing lines (2). Third, this non-potable water is used for tasks that do not require drinking-quality water, such as urban gardening and washing vehicles (3). This logical sequence matches Option A.

Statement I is correct because watershed management is an integrated approach to environmental care. It focuses on the sustainable management and recovery of all interconnected resources within a drainage basin, including soil, surface water, groundwater, forests, and livestock. Statement II is incorrect because watershed management does not ban farming or exclude human activity. Instead, it works to improve rural livelihoods by introducing sustainable agriculture, preventing soil erosion, and ensuring long-term resource security. Therefore, only Statement I is correct, validating Option A.

Percolation tanks are engineered recharge structures used in watershed management. They are built by constructing small earthen dams across seasonal streams to intercept and pool rainwater runoff. By holding this water in an open basin, the tank slows down the surface flow and gives water time to seep through the soil layers. This process replenishes the underlying water table and raises water levels in nearby wells, validating Option B.

Statement I is incorrect because selling or privatizing public water assets often cuts off access for vulnerable rural households, which goes against the equitable distribution goals of watershed programs. Statement II is correct because long-term resource management relies on local public participation. When community members help build and maintain check dams, they take better care of those structures. Programs like the Haryali project use this model by providing funds to Gram Panchayats, allowing villages to manage their own water, farming, and tree-planting projects. Thus, only Statement II is true, validating Option B.

The case study of Ralegan Siddhi highlights how a shared sense of community drove its developmental success. While local residents contributed physical labor (Shramdaan) to repair the village percolation tank and build check dams, those who had moved away for employment found other ways to pitch in. To ensure they contributed equally to the village's development, these non-resident villagers committed one month's salary each year to the community fund. This financial support helped pay for materials and project expenses, validating Option B.

The Haryali project is a Central Government watershed development program executed by local Gram Panchayats. Unlike single-focus engineering projects, Haryali is designed to improve multiple parts of the rural economy at once. Its goals include helping rural communities harvest rainwater to secure clean drinking water, expand irrigation, develop local fisheries, and support afforestation projects. Building a village fish pond and planting trees around it directly aligns with the program's focus on aquaculture and reforestation, validating Option B.

Statement I is correct because the Atal Bhujal Yojana focuses its resources on a specific group of over-extracted ground water blocks. The 7 selected states contain approximately 37% of the total water-stressed blocks across the country. Statement II is incorrect because the scheme is not implemented nationwide across all 28 states. Instead, it targets 7 states facing severe aquifer depletion (Gujarat, Haryana, Karnataka, Madhya Pradesh, Maharashtra, Rajasthan, and Uttar Pradesh). Because only Statement I is correct, Option A is the right choice.

The Neeru-Meeru ("Water and You") initiative in Andhra Pradesh follows a clear step-by-step process. It begins by engaging the public and securing community participation through local education and outreach (1). Once the community is organized, they work together to construct water-harvesting structures, such as percolation tanks, continuous contour trenches, and check dams (2). Finally, these structures collect monsoon runoff, which recharges local aquifers, improves water security, and rejuvenates the village environment and economy (3). This sequence matches Option A.

The Arvary Pani Sansad in Alwar, Rajasthan, is a classic example of integrated water resource management. Instead of relying on top-down government programs, local communities formed a grassroots river parliament to manage their resources together. They built traditional earth structures called Johads to capture rainwater, check soil erosion, and recharge local aquifers. This approach links water management with forestry and farming, demonstrating an integrated system that balances environmental health with community needs, validating Option C.

Rainwater harvesting provides major benefits for growing cities and towns. As urban populations expand and industrial activities increase, the demand for clean water quickly outstrips what municipal utilities can supply. This resource gap often leads to groundwater over-extraction and seasonal water shortages. Rooftop rainwater harvesting allows communities to capture precipitation directly on-site. This provides a reliable alternative source for non-potable household uses and helps reduce the strain on public water infrastructure, validating Option B.

India has evolved region-specific rainwater harvesting systems suited to local climatic conditions. In the arid regions of Rajasthan, Kunds or Tankas are covered underground tanks constructed to collect and store rainwater, making 1-A correct. In Tamil Nadu, Eris are interconnected irrigation tanks or lakes that capture monsoon runoff for agriculture, making 2-B correct. In the Western Himalayan region, Guls/Kuls are traditional channels that divert glacier melt and stream water to agricultural fields, making 3-C correct. Rooftop rainwater harvesting involves collecting rainwater falling on roofs for storage or groundwater recharge, making 4-D correct. Therefore, the correct matching is 1-A, 2-B, 3-C, 4-D, i.e., Option A.

Rainwater harvesting helps reduce energy use through a straightforward hydrogeological process. In areas where groundwater is over-extracted, the water table drops, requiring high-power electric pumps to lift water from deep wells. By capturing rainwater and directing it into recharge pits and borewells, communities replenish these underground aquifers. As the water table rises closer to the surface, wells require less pumping lift. This reduction in pumping depth lowers the electricity needed to draw groundwater, saving energy for the community, validating Option B.

Rainwater harvesting helps stabilize local soils by managing surface runoff. During heavy rains, water flows quickly across open fields, gaining enough speed to detach and carry away fertile topsoil. By catching this water on rooftops or in harvesting basins and directing it into filtration pits, wells, and borewells, these systems reduce the amount of water flowing across the landscape. Slipped runoff speeds prevent water from eroding the ground, protecting topsoil and reducing local flooding, validating Option B.

The provided passage details a clear cause-and-effect relationship regarding the village's water projects. It notes that the initial percolation tank could not hold water because its embankment wall leaked. When the community worked together to repair the wall, the tank began storing water correctly. This allowed water to seep into the ground and recharge local wells, leading to an immediate result stated in the text: "The seven wells below it swelled with water in summer for the first time in the living memory of the people." This confirms Option C.

The text provides clear evidence of the community's self-reliance through the construction of its school. The passage states: "A Rs.22 lakh school building was constructed using only the resources of the village. No donations were taken." By refusing outside financial aid and using local resources and managed loans, the community demonstrated that water security could help a village fund its own public infrastructure, validating Option B.
