  • Parliament clears renaming of Kerala to “Keralam”

    Why in the News

    Both Houses passed a Bill to rename Kerala as “Keralam”, its name in Malayalam. The change follows two resolutions of the Kerala Assembly and routes through the constitutional process for altering a state’s name.

    How is a state renamed under the Constitution?

    1. Parliament’s power: Under Article 3, Parliament can alter the name of a state by law.
    2. Presidential referral: Such a Bill needs the President’s recommendation and the views of the affected state legislature.
    3. Simple majority: The change is passed by ordinary legislative majority, not a constitutional amendment.

    Why “Keralam”?

    1. Linguistic identity: “Keralam” is the state’s name in Malayalam, and the change aligns official usage with local usage.
    2. Assembly resolutions: The Kerala Assembly twice sought the change unanimously.

    Why does the process matter?

    1. Union primacy: Only Parliament, not the state, can effect the legal renaming.
    2. Federal courtesy: The state legislature’s view is sought, but its resolution is not binding.

    Back2Basics: Article 3 of the Constitution

    1. Scope: Formation of new states and alteration of areas, boundaries, or names of existing states.
    2. Initiation: Only on the President’s recommendation, after seeking the state legislature’s views.
    3. Nature: Treated as an ordinary law, reflecting the “indestructible states” feature of Indian federalism.

    “[2022, GS1, 15] The political and administrative reorganization of states and territories has been a continuous ongoing process since the mid-nineteenth century. Discuss with examples.”

    [2025] Consider the following pairs :
    State:Description
    1. Arunachal Pradesh: The capital is named after a fort, and the state has two National Parks
    2. Nagaland: The State came into Existence on the basis of a Constitutional Amendment Act.
    3. Tripura: Initially a Part ‘C’ State, it became a centrally administered territory with the reorganization of State in 1956 and later attained the status of a full-fledged State
    How many of the above pairs are correctly matched?

    [A] Only one

    [B] Only two

  • Tribal Council says Shompen concerns overlooked in the Great Nicobar Island project

    Why in the News?

    The Tribal Council of Great and Little Nicobar has raised concerns that the Great Nicobar Island (GNI) Project could lead to assimilation and disturbance of the Shompen, a Particularly Vulnerable Tribal Group (PVTG).

    What is the GNI Project?

    • Large infrastructure and township project in Great Nicobar.
    • Estimated cost: around ₹91,000 crore.
    • Includes a proposed power plant at Galathea, near Shompen settlements.

    Who are the Shompen?

    • Hunter-gatherer indigenous community.
    • Fewer than 300 members.
    • Recognised as a PVTG.
    • Their isolation makes contact, displacement and forced assimilation particularly sensitive.

    What are PVTGs?

    • PVTG = Particularly Vulnerable Tribal Group: Identified based on characteristics such as:
    • Pre-agricultural technology
    • Low literacy
    • Stagnant or declining population
    • Economic backwardness
    • India recognises 75 PVTGs.

    Key Concerns

    • Assimilation: Proposal to shift the Shompen towards a modern lifestyle.
    • Displacement: Concern over possible settlement and relocation.
    • Consent: Questions regarding consultation over wildlife reserves and project decisions.
    • Health risks: Contact with isolated communities can expose them to diseases and other risks.
    • Assurance gap: Earlier assurance stated that the project would not disturb or displace the Shompen.

    Laws Protecting Tribal Rights

    • Forest Rights Act, 2006: Recognises individual and community forest rights.
    • PESA, 1996: Provides self-governance and consent provisions in Scheduled Areas.
    • Andaman and Nicobar Islands (Protection of Aboriginal Tribes) Regulation, 1956: Restricts entry into tribal reserves.

    Government Initiatives

    • PM-JANMAN: Development of PVTG households and habitations.
    • Development of PVTGs Scheme: Habitat-specific support for 75 PVTGs.

    “[2009] In which one of the following places is the Shompen tribe found?

    (a) Nilgiri Hills

    (b) Nicobar Islands

    (c) Spiti Valley

    (d) Lakshwadeep Islands

  • Monsoon revived, but why there’s cloud over the farm

    Why in the News?

    The southwest monsoon’s revival in July, despite a strengthening El Nino, has sharply narrowed the gap in area sown under kharif crops this season. The relief exposes a deeper tension between a recovering kharif and the mounting risks to the rabi season and to food inflation from El Nino’s lagged effect and a surge in global vegetable oil prices.

    Why did a sowing gap open and how did July reverse it?

    1. Weak start: Rainfall in June was 38 percent below the long period average, making it the sixth driest June in India since 1901, with not a single low pressure system forming.
    2. Early shortfall: By 6 July farmers had planted only 350.85 lakh hectares, which was 20.8 percent below the 442.80 lakh hectares sown in the same period of 2025.
    3. July turnaround: In July the country recorded four low pressure systems against a normal of three. These moved slowly, producing about 24 affected days against a normal of 14, lifting all India July rainfall to 2.4 percent above the average.
    4. Recovery: By 7 August the 967.92 lakh hectares covered was only 1.8 percent lower than last year, with the pulses gap down to 1.8 percent, cotton to 0.4 percent, and oilseeds exceeding last year’s level.

    What is El Nino and why does its effect lag?

    1. Definition: El Nino is the abnormal warming of surface waters in the central and eastern Pacific Ocean off Peru and Ecuador that suppresses monsoon rainfall over India.
    2. Lagged impact: El Nino’s effect on rainfall and temperatures comes with a lag of one to two months and can play out over five to six months or more.
    3. Current phase: It intensified from a weak to moderate phase in June into a moderate to strong event in July, and global agencies expect it to turn very strong during October to December.

    Why is the worst not yet over?

    1. Late kharif needs rain: Crops need rainfall during August and early September for flowering and grain formation that determine yields. Meteorological Department has predicted a fresh low pressure system around 12 August.
    2. Delayed hit: Because El Nino’s rainfall suppressing effect lags, its worst impact is still to come.
    3. Rabi at risk: A strengthening El Nino raises temperatures, and a short warm winter harms wheat, mustard and potato yields, so the real threat is to the rabi season.

    What does the FAO Food Price Index show?

    1. Index high: The United Nations Food and Agriculture Organization (FAO) food price index touched 131.1 points in July, up 1 percent from July 2025 and the highest since the 131.4 of January 2023, a three and a half year high. This means food prices are now at their highest level in about 3½ years.
    2. Vegetable oils drive it: The vegetable oils index reached 195.7 points, up 17.3 percent year on year and the highest since June 2022.
    3. Mixed components: The cereals index was 113.8 points, up 6.9 percent, while dairy fell 24.8 percent, sugar fell 8 percent, and meat rose just 0.8 percent.
    4. Causes: The rise is attributed to El Nino, heatwave hit crop yields in Europe, and supply disruptions from conflicts in West Asia and Ukraine.

    Why are vegetable oils the real concern for India?

    1. Import exposure: The combined value of India’s imports of oilseeds, pulses and cotton was close to 25 billion dollars in 2025-26, which El Nino could push to a new high.
    2. Biofuel diversion: Firming vegetable oil prices stem mainly from diversion of palm, rapeseed and soyabean oil toward biofuel as petroleum prices harden.
    3. Fuel substitution: These oils are used to make fatty acid methyl esters, a substitute for petroleum diesel, linking food and fuel markets.
    4. Buffer available: The government held 92.6 million tonnes of rice and wheat on 1 July against a required minimum of 41.1 million tonnes, plus over 4 million tonnes of pulses, which can be offloaded to contain inflation.

    Conclusion

    The July monsoon revival has rescued the kharif season, cutting the sowing gap to under 2 percent even as El Nino strengthened. The central worry has shifted to the rabi season and to food inflation, since El Nino’s temperature and rainfall effects lag and global vegetable oil prices are at multi year highs. Ample public grain stocks give the government room to manage food inflation, but the rabi outlook and edible oil import bill remain the open risks.

    Back2Basics:

    Foundational Context: Climate Change and Food Security

    1. About: Food security means reliable physical and economic access to sufficient, safe and nutritious food, which climate variability directly threatens.
    2. Tropical vulnerability: Tropical countries face greater exposure because agriculture is rain dependent and heat sensitive.
    3. India context: A large share of India’s cropped area is rainfed, tying output to monsoon performance.
    4. Transmission channels: Erratic rainfall, heat stress, pest incidence and global price shocks each transmit climate risk to food systems.

    FAO Food Price Index

    1. Convening body: Published by the United Nations Food and Agriculture Organization (FAO).
    2. What it measures: A weighted average of world prices of a basket of food commodities against a base period value taken as 100 for 2014 to 2016.
    3. Components: Tracks separate indices for cereals, vegetable oils, dairy, meat and sugar.
    4. Frequency: Released monthly.
    5. Recent reading: Touched 131.1 points in July, a three and a half year high.

    Government Initiatives for Agriculture and Edible Oils

    1. National Mission on Edible Oils Oil Palm: Mission to raise domestic oil palm and edible oil production and cut import dependence.
    2. PM-AASHA: Umbrella scheme assuring remunerative prices to farmers, especially for oilseeds and pulses.
    3. Price Stabilisation Fund: Buffer stock mechanism to moderate volatility in pulses and other commodities.
    4. Minimum Support Price: Price assurance to encourage sowing of pulses and oilseeds.

    Key Facts about the Monsoon and Kharif Season

    1. Sixth driest June: June 2026 was the sixth driest June since 1901.
    2. July rainfall: All India July rainfall was 2.4 percent above the long period average.
    3. Import bill: Oilseeds, pulses and cotton imports neared 25 billion dollars in 2025-26.
    4. Grain stocks: 92.6 million tonnes of rice and wheat held on 1 July against a 41.1 million tonne minimum.

    Challenges in Indian Agriculture

    1. Rainfall dependence: A large rainfed area leaves output exposed to monsoon swings.
    2. Import reliance: High dependence on imported edible oils and pulses exposes India to global prices.
    3. Climate volatility: El Nino and heatwaves disrupt both kharif and rabi seasons.
    4. Price transmission: Global food and fuel price shocks feed domestic inflation.
    5. Storage and logistics: Post harvest losses and uneven buffer management persist.
    6. Yield gaps: Low productivity in pulses and oilseeds constrains self sufficiency.

    Way Forward

    1. Raise oilseed output: Expand area and yields under the edible oils mission to cut imports.
    2. Diversify cropping: Promote pulses and climate resilient varieties in rainfed regions.
    3. Strengthen buffers: Use public grain and pulse stocks proactively to contain inflation.
    4. Improve forecasting: Sharpen monsoon and El Nino forecasting for sowing decisions.
    5. Invest in irrigation: Extend micro irrigation to reduce rainfall dependence.

  • Ladakh’s glaciers are slowing as the mountains warm

    Why in the News?

    A new study in the journal The Cryosphere reports that glaciers in the Zanskar region of Ladakh are moving more slowly than they did 30 years ago, as sustained warming thins them and reduces their driving force. The slowdown carries long term implications for the Indus basin, where glacier melt sustains river flows during dry summer months.

    Why are the Zanskar glaciers slowing down?

    1. Thinning mechanism: When a glacier loses more ice than it gains over many years it becomes thinner, and thinner ice exerts less driving force, causing it to flow more slowly.
    2. Warming link: The study connects mass loss, thinning and reduced flow, showing that thinning is not only a consequence of warming but also weakens the glacier’s ability to move.
    3. Downstream effect: Slower flow means the lower parts of a glacier receive less replenishment from higher elevations, making continued shrinkage more likely.
    4. Local variation: Glacier geometry, debris cover and conditions at the snout influence how quickly each glacier responds.

    What is peak water?

    1. Definition: Peak water is the point at which increased melting from a shrinking glacier temporarily raises river runoff before the water supply begins to decline.
    2. Why it matters: More melting may boost flows in the near term, but once glaciers lose a substantial fraction of their stored ice, their meltwater contribution to rivers is expected to drop.

    What did the study find?

    1. Study design: The researchers examined how glacier flow changed from 1992 to 2023 across 12 glaciers in the Zanskar Himalaya using satellite derived surface velocities.
    2. Velocity decline: Glaciers slowed by 2.4 metres per year per decade on average.
    3. Faster thinning: The pace of surface thinning increased from around 0.22 metres per year between 2000 and 2005 to around 0.57 metres per year between 2015 and 2020.
    4. Sample caveat: The 12 glaciers studied are representative, but the Zanskar basin hosts around 1,755 glaciers, so caution is needed before extending the findings to all of Ladakh.

    What are the implications for the Indus basin?

    1. Summer flows: Glacier melt contributes significantly to Indus river flows during the dry summer months, so long term storage decline threatens that supply.
    2. Multiple dependencies: River flows also depend on snowfall, rainfall, groundwater and water management, so slowing glaciers alone will not immediately cause shortages.
    3. Sectors at risk: Continued thinning and slowdown signal declining long term water storage, with implications for water security, agriculture, hydropower and downstream ecosystems in coming decades.

    Why do the study’s own limitations qualify its conclusions?

    1. Sub surface blind spot: Satellite surface velocity observations cannot directly reveal processes beneath the glacier, such as subglacial hydrology or basal sliding, which strongly influence motion.
    2. Data gaps: Long term field measurements of ice thickness, mass balance and bed conditions remain limited in the region, making full attribution of observed changes difficult.
    3. Exceptions to the trend: Some glaciers can temporarily accelerate due to increased meltwater at the bed, glacier surges, or interactions with proglacial lakes.

    What does the global comparison show?

    1. European Alps and Alaska: Similar glacier slowdowns have been reported, driven by the same thinning and reduced driving stress mechanism.
    2. Canadian Arctic and Andes: These regions show comparable slowdowns linked to warming.
    3. Tibetan plateau: Parts of the plateau display the same dominant mechanism of thinning leading to slower flow.
    4. Shared lesson: Glacier slowdown is becoming widespread globally, though local glacier characteristics still shape individual behaviour.

    Conclusion

    The study establishes that Zanskar glaciers are not only losing mass but slowing down, with thinning reducing their capacity to move and replenish lower reaches. This points to a long term decline in stored water that will eventually reduce Indus basin flows after a phase of peak water. The findings underscore the need for sustained ground based monitoring to validate satellite data and to prepare downstream communities for shifting water availability.

    Back2Basics:

    Foundational Context: The Cryosphere and Himalayan Glaciers

    1. About: The cryosphere comprises the frozen parts of the Earth, including glaciers, snow cover, permafrost and ice, that store and release freshwater.
    2. Third Pole: The Hindu Kush Himalaya holds the largest ice mass outside the polar regions and is often called the Third Pole.
    3. Function: Himalayan glaciers act as natural reservoirs, releasing meltwater in warmer months to sustain rivers, agriculture and ecosystems in otherwise arid areas.
    4. Climate indicator: High altitude glaciers respond distinctly to warming, making them valuable natural indicators of environmental change.

    The Zanskar Region and Indus Basin

    1. Location: The Zanskar region lies in Ladakh and hosts some of the largest and most extensive glaciers in the Himalaya.
    2. Climatic setting: Its glaciers receive most of their snowfall from mid latitude westerly disturbances during winter and sit at high altitude.
    3. Indus basin: The Indus rises in the Tibetan plateau and flows through Ladakh, with glacier melt feeding its dry season flows.
    4. Significance: The basin supports water security, agriculture and hydropower across northern India and beyond.

    Key Facts about Himalayan Glacier Monitoring

    1. Study journal: The findings appear in the journal The Cryosphere.
    2. Zanskar glacier count: The basin hosts around 1,755 glaciers, of which 12 were studied.
    3. Observation record: The study covers more than 30 years, from 1992 to 2023.
    4. Peak water: A key concept describing the temporary runoff increase before long term decline.

    Challenges in Glacier Conservation and Monitoring

    1. Data scarcity: Long term field measurements of ice thickness and mass balance are limited in high altitude terrain.
    2. Warming pace: Rising temperatures accelerate thinning and mass loss.
    3. Black carbon: Soot deposition on ice lowers reflectivity and speeds melting.
    4. Glacial lake hazards: Meltwater expansion raises the risk of glacial lake outburst floods.
    5. Downstream dependence: Millions rely on glacier fed rivers, amplifying the impact of any decline.

    Way Forward

    1. Expand ground monitoring: Add measurements of ice thickness, mass balance and meltwater discharge to validate satellite data.
    2. High altitude weather stations: Install continuous observation stations to capture varied mountain climate conditions.
    3. Basin water planning: Prepare Indus basin water management for the eventual decline after peak water.
    4. Reduce black carbon: Cut regional emissions that hasten glacier melt.
    5. Regional cooperation: Share transboundary glacier and river data across the basin.

  • Monsoon revives but El Nino threatens the rabi crop

    Why in the News

    The southwest monsoon has revived, cutting the seasonal deficit to 11.5%, but warns that a possible El Nino threatens the rabi crop and keeps urea supply in focus.

    What is El Nino?

    1. Definition: El Nino is the abnormal warming of the central and eastern Pacific that weakens the Indian monsoon and disrupts rainfall.
    2. Crop link: A weak or erratic monsoon reduces soil moisture and reservoir storage needed for the winter rabi crop.

    Why does the rabi outlook matter?

    1. Food and prices: Wheat and other rabi crops shape food inflation and buffer stocks.
    2. Input dependence: Adequate urea and irrigation are needed to protect rabi output if rainfall falters.
    3. Recovery is partial: A narrowed deficit does not remove the risk that late-season El Nino conditions bring.

    Conclusion

    A recovering monsoon eases the kharif outlook but leaves rabi exposed to El Nino. The next milestone is confirmation of El Nino conditions before the rabi season.

  • How common are cloudbursts in India?

    Why in the News?

    Flash floods triggered by a cloudburst struck Pahalgam in Anantnag on 12 July. Last week, the India Meteorological Department (IMD) rejected claims that cloudbursts caused the recent floods in Assam and Nagaland. The two events have renewed attention on the scientific definition of a cloudburst and its frequent misuse in public discourse.

    What counts as a cloudburst under the IMD’s definition?

    1. Threshold: The IMD defines a cloudburst as 10 centimetres or more of rainfall in an hour over a small area of around 20 to 30 square kilometres.
    2. Scale comparator: Indore receives about 1,062 millimetres of rain in an average year, so a single cloudburst can dump close to 10% of a full year’s rainfall in 60 minutes.
    3. Related category: Some scientists have proposed a mini cloudburst category for 5 centimetres of rain in an hour over the same area, since local topography can make even this devastating.

    How does a cloudburst form?

    1. Initial lift: Warm, moist air rises rapidly through convection, and in mountainous terrain this rise is intensified by orographic lifting, where monsoon winds are forced upward by steep slopes.
    2. Cloud growth: As the rising air cools, water vapour condenses into towering cumulonimbus clouds that can reach up to 15 kilometres in height.
    3. Suspension: Strong upward currents keep forming raindrops suspended in the cloud for longer instead of letting them fall immediately.
    4. Discharge: When the weight of accumulated water exceeds what the updraft can hold, or the updraft weakens, the suspended water falls in one release rather than as steady rain.

    How common are cloudbursts in India, and why are they hard to count?

    1. Historical count: Parliament was told in 2019 that the IMD recorded only around 30 cloudburst incidents between 1970 and 2016, a figure many experts consider an underestimate.
    2. Rising frequency: Global warming increases the amount of moisture the atmosphere can hold, making cloudbursts more frequent even though they remain rare compared with ordinary heavy rain.
    3. Monitoring gap: Most cloudbursts occur in remote, high altitude regions where rain gauges and weather stations are sparse, so an event even a few kilometres from a monitoring station may go officially unrecorded despite causing large scale destruction downstream.
    4. Regional concentration: Uttarakhand, Himachal Pradesh, and Jammu and Kashmir have reported a recent surge in events described locally as cloudbursts, particularly in July and August.

    Does the label obscure accountability for poor planning?

    1. Blame diffusion: Calling a heavy downpour a cloudburst turns it into a singular, unforeseeable act of nature, which is harder to do when the stated cause is heavy rain combined with poor drainage.
    2. Dharali precedent: During the 2025 Dharali floods in Uttarakhand, initial reports blamed a cloudburst, but meteorological data later showed the rainfall rate was well below the cloudburst threshold. The underlying causes were illegal construction on riverbeds, deforestation that left soil vulnerable to erosion, and the absence of drainage infrastructure along new all weather roads.
    3. Assam and Nagaland claims: The IMD last week rejected reports that cloudbursts caused recent floods in Assam and Nagaland, including the Upper Assam floods.
    4. Accountability questions avoided: Had the Dharali downpour genuinely been a cloudburst, officials could have avoided questions about why the state permitted construction in high risk zones and why early warning systems failed.

    Why are cloudbursts difficult to forecast?

    1. Model resolution: Weather models estimate average conditions across grid cells, while a cloudburst occurs over an area smaller than a single cell, so detecting one requires high resolution models needing computing power not always available.
    2. Speed of formation: Cloudbursts develop and strike quickly, unlike cyclones or monsoon systems that can be tracked for weeks, leaving forecasters far less data to work with.
    3. Terrain interference: Doppler weather radars emit and receive beams that mountains can block, creating blind spots in exactly the high altitude terrain where cloudbursts are most common.
    4. Sparse instrumentation: Rugged terrain also means fewer automatic weather stations, leaving fewer ground sensors to feed real time data into short term prediction.

    What is India doing to improve cloudburst forecasting?

    1. Nowcasting: The IMD is developing nowcasting technology to issue short term alerts every few hours rather than long range forecasts.
    2. Mission Mausam: Under the government’s Mission Mausam programme, India plans to more than double its radar network from about 40 radars currently and use artificial intelligence to better predict hyperlocal events.
    3. Persistent limits: Even with better technology, a cloudburst is expected to remain harder to predict than a typical rainstorm because of how localised and fast forming it is.

    Conclusion

    A cloudburst is a specific meteorological event defined by the IMD’s own rainfall threshold, not a synonym for any destructive downpour. Attributing flood damage to a cloudburst without checking recorded rainfall data lets authorities treat the disaster as an unforeseeable act of nature rather than examine illegal construction, deforestation and drainage failure. India’s forecasting improvements under Mission Mausam target the science of prediction, but they do not by themselves fix the planning failures the label has repeatedly been used to obscure.

  • Outdated contraception, early conception: Counting the babies that India didn’t plan for

    Why in the News

    India’s total fertility rate has fallen to the replacement level of about two children per woman, a figure widely read as proof the country has completed its demographic transition. This headline number conceals a persistent gap between how many children women actually want and how many they have, meaning India’s fertility decline is a policy problem rather than a solved story.

    What is the difference between the Total Fertility Rate and the Wanted Fertility Rate?

    1. Total Fertility Rate (TFR): TFR is the average number of births per woman across her reproductive years, counting all births including those women did not plan or want.
    2. Wanted Fertility Rate: This counts only births that match what women say they intended, revealing their actual preferred family size.
    3. The national gap: Nationally, women have an average of 2.0 children while their desired family size is about 1.6, a gap of 0.4 children per woman.
    4. States with the widest gap: Eight states, Uttar Pradesh, Bihar, Jharkhand, Rajasthan, Madhya Pradesh, Chhattisgarh, Assam and Haryana, have a gap of more than 0.3 children per woman.

    Why has India reached low fertility despite near-universal marriage?

    1. Marriage pattern: Only about 1% of women remain never married by ages 45 to 49, and the median age at first birth is 21.2 years, unlike most low-fertility countries where late marriage drives the decline.
    2. Sterilisation-led control: Indian women largely control fertility by having children, reaching their desired family size, and then permanently stopping through sterilisation, rather than through methods that space births.
    3. Missing spacing tools: Tools that help young couples delay a first birth or space children are largely missing, so unintended pregnancies cluster in the early years of marriage among the youngest women.
    4. Health consequence: This pattern is also reflected in relatively poor maternal and child health outcomes.

    Does India’s low fertility number hide a larger unmet need than it appears?

    1. Informed choice gap: Informed choice around sterilisation remains partial, with many women undergoing the procedure without fully informed consent. When these women are counted alongside those with unmet contraceptive needs, India’s “unwanted family planning” problem appears much larger than TFR figures suggest.
    2. Son preference inflation: In several states, families do not stop having children after one or two. In fact they continue until they have a son, meaning a disproportionate share of historically recorded “unwanted” births were daughters.
    3. Progress already visible: Unintended pregnancies have fallen from 21% in 2005-06 to 8% in 2019-21, and son preference is slowly weakening among younger and more educated families.

    Conclusion

    The article’s central argument is that India’s near-replacement TFR is not evidence the fertility story is finished, since it rests on a gap between wanted and actual fertility sustained by late spacing, partial informed choice, and residual son preference. What remains unresolved is the recent decline in modern contraceptive method use, which risks keeping the country’s unwanted-fertility gap in place even as the headline birth rate keeps falling.

    Back2Basics:

    Total Fertility Rate (TFR)

    1. Definition: TFR is the average number of live births a woman would have by the end of her reproductive years, calculated from age-specific fertility rates for ages 15 to 49.
    2. Source: TFR is tracked through the Sample Registration System (SRS) and the National Family Health Survey (NFHS).
    3. Replacement level: A TFR of 2.1 is generally considered replacement level; India’s national TFR has reached around 2.0, with Bihar at 2.9 against Kerala and Tamil Nadu at around 1.8.

    Understanding “Replacement Level” (2.1)

    1. The “0.1” Factor: The extra 0.1 accounts for the fact that some children do not survive to reproductive age, and slightly more boys are born than girls.
    2. Developing vs. Developed: In countries with high infant mortality rates, the replacement level can actually be much higher than 2.1 (sometimes up to 2.5 or 3.0) to stabilize the population.

    Linkage: The PYQ examines how demographic trends influence India’s development prospects. The article shows that replacement-level fertility alone does not ensure a demographic dividend, as unmet family planning needs persist.

  • Pollens Help Trace Why the Harappan Civilization Shrank

    Why in News?

    A study by the Birbal Sahni Institute of Palaeosciences (BSIP) has used pollen preserved in lake sediments from Deoria Tal (Garhwal Himalaya) to reconstruct past climate. The findings suggest that a prolonged weakening of the Indian Summer Monsoon (ISM) and the 4.2 ka climatic event contributed to the decline and eastward migration of the Harappan Civilization.

    Key Findings

    • Analysis of pollen and spores reconstructed vegetation and monsoon history over the last ~5,100 years.
    • Around 4200 years BP [Before Present](4.2 ka event), the region experienced an abrupt cool and dry climate with a weakened ISM.
    • Reduced monsoon weakened the perennial river systems of the Indus and Ghaggar-Hakra, making agriculture difficult.
    • This likely triggered the migration of Harappan populations towards the Ganga plains, contributing to the shrinking of the civilization.
    • The study establishes a strong link between abrupt climate change and changes in ancient human settlements.

    How Did Scientists Reconstruct the Past?

    • Sediment core collected from Deoria Tal in Uttarakhand.
    • Pollen analysis (Palynology) reconstructed past vegetation and climate.
    • Chronology established using 10 AMS Radiocarbon (¹⁴C) dates on Trapa (water chestnut) seed cases.
    • Changes in the Oak/Pine pollen ratio served as an indicator of changing temperature and monsoon strength.

    What is the 4.2 ka Event?

    • A major global climatic event that occurred around 4200 years ago.
    • Characterized by:
      • Weak Indian Summer Monsoon.
      • Cooler and drier climate.
      • Widespread droughts across several ancient civilizations.
    • Linked to the decline of civilizations such as Harappan Civilization, Akkadian Empire, and Old Kingdom of Egypt

    Why Did the Monsoon Weaken?

    Researchers attribute the weakened ISM to multiple interacting climatic factors:

    • Southward shift of the Inter Tropical Convergence Zone (ITCZ).
    • Strong El Niño conditions.
    • Strong negative phase of the Indian Ocean Dipole (IOD).
    • Reduced Northern Hemisphere summer insolation.

    Other Climate Phases Identified

    • Roman Warm Period (2500 to 1450 cal yr BP): Strong ISM and higher agricultural productivity.
    • Medieval Climate Anomaly (1050 to 650 cal yr BP): Strong monsoon due to northward ITCZ.
    • Little Ice Age (650 to 100 cal yr BP / CE 1350 to 1850): Weak ISM associated with stronger westerlies, ENSO and southward ITCZ.

    [2026] Consider the following statements about the archaeological findings in Harappan towns:
    I. There is wide occurrence of spindle-whorls in the houses but absence of spinning wheels.
    II. Weights and measurement scales, complete with graduations have been discovered.
    III. There are houses built in large part with baked bricks, around relatively spacious courtyards, with their own wells, bathing platforms, and large rooms.
    Which of the following inferences can be drawn from the above statements?
    1. Statement I suggests that spinning was a laborious activity done at home.
    2. Statement II suggests the extent of the scientific knowledge that the Harappans possessed.
    3. Statement III suggests the emergence of a common property system.

  • Pandavani Legend Teejan Bai Passes Away

    Why in News?

    Padma Vibhushan awardee Teejan Bai (1956–2026), the foremost exponent of Pandavani, passed away at AIIMS Raipur. She played a pivotal role in taking Chhattisgarh’s traditional folk art to the global stage.

    Key Highlights

    • Born in Ganiyari village (Durg district), Chhattisgarh.
    • Learned Pandavani from her maternal grandfather Brajlal Pardha and gave her first public performance at 13 years of age.
    • Broke gender barriers by performing in the Kapalika style, traditionally reserved for men.
    • Performed in over 17 countries, popularising Indian folk traditions worldwide.
    • Received the Padma Shri, Padma Bhushan, and Padma Vibhushan.

    About Pandavani

    • A traditional folk storytelling and musical art form of Chhattisgarh.
    • Narrates episodes from the Mahabharata through singing, narration, acting, and dialogue.
    • The performer uses a tanpura (tambura) as both a musical instrument and a symbolic prop.

    Two Styles of Pandavani

    • Vedamati Style: Performed while sitting, with greater emphasis on narration.
    • Kapalika Style: Performed while standing, combining dramatic acting, gestures, expressions, and dialogue.

  • A growth story that needs women at work

    Mentor’s Comment

    With India’s youth unemployment already double its 2012 rate and GDP growth slower than official figures suggest, critics argue that India cannot sustain rapid growth or reach Viksit Bharat by 2047 while excluding half its population, women, from productive work.

    Why does raising female work participation matter for growth itself, not just for equity?

    1. Direct growth arithmetic: A 10 percentage point rise in India’s female Work Participation Rate (WPR) could add nearly two percentage points to GDP growth.
    2. Labour supply channel: More women in paid work expands the economy’s productive capacity and raises household incomes, consumption, and savings.
    3. Human capital channel: Higher household incomes from women’s earnings improve children’s nutrition, education, and healthcare, strengthening long term human capital.
    4. Productivity channel: Citing Nobel laureate Claudia Goldin, gender diverse workplaces are more efficient, creative, and competitive, making women’s inclusion a productivity strategy, not only a welfare measure.

    What explains the decline and stagnation in women’s work participation since the 1980s?

    1. Structural shift away from farming: As structural transformation reduced agriculture’s role between 2004-05 and 2012, mechanisation and falling demand for manual labour pushed rural women out of the workforce.
    2. The COVID reversal was distress, not choice: Post-2020 gains in women’s participation followed a GDP slowdown since 2017; return migration from cities pushed women into unpaid family labour in subsistence agriculture, a “distress driven feminisation of agriculture.”
    3. Capital intensive growth excludes women: India’s recent GDP growth has concentrated in capital intensive sectors like finance and information technology, which absorb few workers, while labour intensive sectors such as textiles and garments saw absolute employment fall between 2013 and 2019.
    4. Manufacturing’s broken promise: Fewer women were employed in manufacturing in 2019 than in 2004, despite Make in India and Performance-Linked Incentive (PLI) schemes; women’s manufacturing employment did not recover to 2004 levels until 2022.

    Why does Tamil Nadu succeed where most of India does not?

    1. Tamil Nadu’s outsized concentration: More than 40% of India’s women factory workers are employed in Tamil Nadu, a state with only 5% to 6% of India’s population.
    2. Sectoral base: This concentration rests on strong textile and garment hubs in Tiruppur and Coimbatore, footwear, electronics assembly in Sriperumbudur, and automobile components.
    3. Enabling conditions: Higher female literacy, greater mobility, and well developed hostel and transport facilities for women workers underpin the sector’s ability to employ women at scale.
    4. The Hindi belt contrast: States there need investment in health (not merely insurance) and public education for girls and women to bring down malnutrition and stunting before they can replicate Tamil Nadu’s outcomes.

    Conclusion

    India’s growth story is incomplete without raising female work participation, and the deficit is concentrated in exactly the sectors, labour intensive manufacturing, that once absorbed women workers and have since collapsed for them. Closing the north-south divide by replicating Tamil Nadu’s combination of sectoral investment, education, and mobility infrastructure is presented as the precondition for India to be “Viksit” by 2047.

    Back2Basics

    1. Work Participation Rate (WPR): The proportion of the population that is economically active (working or seeking work); distinct from the unemployment rate, which measures only those seeking work among the labour force.
    2. U-shaped curve (Claudia Goldin): The empirical pattern where female labour force participation first falls as an economy industrialises and household incomes rise, then rises again as education and the services sector expand, a pattern India’s data through 2018-19 is shown to follow.

    Question (2014): Discuss the various economic and socio-cultural forces that are driving increasing feminization of agriculture in India.
