Question map
Consider the following statements : Statement-I : According to the United Nations' World Water Development Report, 2022', India extracts more than a quarter of the world's groundwater withdrawal each year. Statement-II : India needs to extract more than a quarter of the world's groundwater each year to satisfy the drinking water and sanitation needs of almost 18% of world's population living in its territory. Which one of the following is correct in respect of the above statements?
Explanation
The correct answer is Option 3 because Statement-I is a factual data point from the UN report, while Statement-II misrepresents the primary driver of groundwater extraction in India.
- Statement-I is correct: According to the United Nations’ World Water Development Report 2022, India is the largest user of groundwater globally, extracting approximately 251 cubic kilometers annually. This constitutes more than 25% (a quarter) of the total global groundwater withdrawal.
- Statement-II is incorrect: While India does support about 18% of the world's population, the vast majority of its groundwater extraction—roughly 89% to 90%—is utilized for agriculture and irrigation (to ensure food security), not for drinking water and sanitation. Domestic and industrial sectors account for only a small fraction (about 5-10%) of the total usage.
Therefore, while the extraction volume mentioned in Statement-I is accurate, the reason provided in Statement-II is false as it ignores the dominant role of the irrigation sector in groundwater depletion.
PROVENANCE & STUDY PATTERN
Full viewThis question is a classic 'Data vs. Usage' trap. While Statement I tests a famous statistic often cited in UN reports and Economic Surveys (India = ~25% global GW extraction), Statement II tests your fundamental NCERT knowledge of 'Water Utilization by Sector'. The trap lies in attributing the massive extraction to 'drinking water' rather than the actual culprit: agriculture.
This question can be broken into the following sub-statements. Tap a statement sentence to jump into its detailed analysis.
- Statement 1: According to the United Nations World Water Development Report 2022, does India extract more than a quarter (>25%) of the world's annual groundwater withdrawal?
- Statement 2: What percentage of the world's population lives in India (is it approximately 18%)?
- Statement 3: Does the United Nations World Water Development Report 2022 (or other authoritative sources) state that India needs to extract more than a quarter of the world's annual groundwater withdrawal to satisfy the drinking water and sanitation needs of the roughly 18% of the world's population living in India?
Gives India's share of world surface area (2.45%), water resources (4%) and population (~17%), showing India has a much larger share of people than of renewable water resources.
A student could combine the 17% population figure with global per‑capita water use data to judge whether India's withdrawals might be disproportionately large relative to its land/water share.
States that about 77% of present groundwater withdrawal in India is used for irrigation, indicating high dependence on groundwater for agriculture.
One can use global irrigation water withdrawal proportions and India's large agricultural sector to estimate whether India's absolute groundwater withdrawal could be a large fraction of the world total.
Describes widespread groundwater overuse (one‑third of country overusing, many districts with large declines), pointing to intensive and growing groundwater extraction.
Combine evidence of overexploitation with India’s population/agricultural area to infer that withdrawals may be large and rising compared with other countries.
Provides state‑level data showing extremely high reliance on wells/tubewells in major irrigated states (e.g., Punjab 76.1% of irrigated area via wells), illustrating concentrated, intensive groundwater use.
A student could map major groundwater‑intensive states (Punjab, Haryana, UP, etc.) against national irrigated area to approximate India’s large absolute groundwater withdrawal.
Lists percentages of groundwater potential exploited by key states (e.g., Punjab ~94%, Haryana 84%), indicating near‑maximal extraction in important agricultural regions.
Using these high exploitation rates in populous/agricultural states, a student could infer that India's per‑area withdrawal is high and consider that this may push India’s share of global withdrawal upward.
- Explicitly states India accommodates 17.8% of the world's total population.
- Provides a recent population total (around 138.77 crore / 1.3877 billion) that matches the stated percentage.
- Gives an India population figure (1,210,193,422) and directly describes it as about 17% of the world population.
- Supports the statement's claim that India's share is near 18% by providing an earlier percentage estimate.
- Provides the 2011 census population (1,210.19 million) and a 2019 estimate (1.368 billion), enabling calculation of India's share versus world population.
- Shows population trend and projections that contextualize small differences between ~17% and ~18% estimates.
Gives India’s share of world population (~17%) and quantifies national annual precipitation/total utilisable water (total utilisable water ≈ 1,122 km3).
A student could compare India’s per‑year utilisable water volumes with global annual groundwater withdrawal figures (from UN/WWDR) to judge whether meeting drinking/sanitation for ~18% population would require >25% of global groundwater withdrawal.
States the total replenishable groundwater resource in India ≈ 432 cubic km per year (explicit national annual replenishable GW volume).
Compare this 432 km3 figure to reported global annual groundwater withdrawal (from UN/WWDR or FAO) to estimate India’s potential share of global withdrawals if India used a large fraction of its replenishable groundwater for drinking/sanitation.
Notes that about 77% of present groundwater withdrawal in India is used for irrigation (i.e., non‑drinking uses dominate GW use).
Use this pattern to infer that a large portion of India’s groundwater is already committed to irrigation, so the fraction available/needed for drinking and sanitation may be substantially less than total withdrawal — compare to global withdrawal breakdowns to assess the plausibility of the >25% claim.
Provides state‑level examples showing very high dependence on wells/tubewells for irrigation (e.g., 76.1% irrigated area in Punjab via wells), illustrating intense local groundwater withdrawals.
A student can extrapolate that localized heavy withdrawal increases national totals; then compare aggregated national groundwater use (implied by heavy irrigation use) with global withdrawal totals from authoritative sources to evaluate the statement.
Gives national estimates of surface and replenishable groundwater combined (1,869 km3) and reiterates India’s ~4% share of world water resources — useful context on national vs global water endowment.
Combine this national resource magnitude with external global groundwater withdrawal numbers to check whether supplying drinking/sanitation for ~18% population would imply extracting >25% of global groundwater withdrawal.
- [THE VERDICT]: Trap. Statement I is a standard 'Report Headline' fact, but Statement II is a 'Causal Fallacy' that contradicts basic NCERT Geography.
- [THE CONCEPTUAL TRIGGER]: NCERT Class XII 'India People and Economy', Chapter 4 (Water Resources) – specifically the section on Sectoral Usage of Water.
- [THE HORIZONTAL EXPANSION]: Memorize the 'Water Profile': India has 2.4% World Land, 4% Water, ~18% Population. Sectoral Usage: Agriculture (~89-90%), Domestic (~5-6%), Industrial (~3-4%). Top GW extractors: India (#1), China, USA. Critical threshold: Per capita availability <1700 m³ (Stress), <1000 m³ (Scarcity).
- [THE STRATEGIC METACOGNITION]: When you read a statistic like '25% of world's groundwater', immediately ask 'Where does it go?'. If the question claims we pump that much just for drinking/sanitation, apply the 'Volume Logic'—humans drink liters, crops drink tons. The claim in Statement II is physically impossible for domestic use alone.
India holds a small fraction of global surface area and freshwater but a large share of the world's population, creating disproportionate per‑capita water pressure.
High-yield for questions on water scarcity and resource stress; links demographic pressure to per‑capita resource availability and sustainable development. Helps answer comparative questions on resource distribution, water security, and policy priorities.

The 'Virtual Water' Concept. Since India exports rice/wheat, we are effectively exporting groundwater. Expect a question on 'Virtual Water Trade' or the 'Falkenmark Water Stress Indicator' (1700 vs 1000 cubic meters thresholds).
Use 'Scale of Consumption' logic. Domestic water use is negligible compared to agriculture. If India needed 25% of the *entire world's* groundwater just to give water to 18% of people, the rest of the world would be dead. The math implies an absurdity. Statement II is false.
Link this to GS3 Agriculture & Economy: The 'Green Revolution' in semi-arid states (Punjab/Haryana) + Free Electricity + MSP for water-intensive crops = Groundwater Depletion. This is a policy-induced ecological disaster, not just a resource constraint.
