rchives (PRELIMS  Focus) Tenth Schedule Category: POLITY Context:  The Supreme Court has strongly criticized the Telangana Assembly Speaker for delaying the decision on disqualification petitions. A Bench led by Chief Justice B.R. Gavai stated that anti-defection cases must be resolved within three months to uphold the dignity of the Speaker’s office and prevent political defection from going unpunished. The Court noted that such proceedings often die a “natural death” due to intentional delays by Speakers, making a mockery of the Tenth Schedule (anti-defection law). It criticized the Telangana Speaker for issuing notices only after the matter was brought to the Supreme Court in January 2025, despite a seven-month delay. Chief Justice Gavai emphasized that no constitutional immunity protects the Speaker from judicial review when acting under the Tenth Schedule, and questioned whether the Speaker acted in an expeditious manner as expected by Parliament. Learning Corner: 52nd Amendment Act and Anti-Defection Law: 52nd Amendment Act, 1985: Added the Tenth Schedule to the Indian Constitution. Aimed at curbing political defections by legislators. Enacted during Rajiv Gandhi’s tenure as Prime Minister. Came into effect on 1 March 1985. Anti-Defection Law (Tenth Schedule): Provides for disqualification of legislators (MPs/MLAs) on grounds of: Voluntarily giving up membership of their party. Voting/abstaining against party directives (whip) without permission. Exceptions: Merger provision: If 2/3rd members of a party merge with another, disqualification does not apply. Decision Authority: The Speaker/Chairman of the House decides disqualification petitions. Source: THE HINDU Linguistic reorganization of states Category: POLITY Context: Tamil Nadu Governor R.N. Ravi criticized the linguistic reorganization of states, claiming it created “second-class citizens” by dividing people based on language. Key Highlights: Historical Background: Before 1956, India’s states were categorized as Part A, B, C, and D, based on colonial legacy and integration history. Linguistic and administrative demands led to calls for restructuring post-Independence. Reorganization of 1956: The States Reorganisation Commission (SRC) was formed in 1953 following widespread protests (notably Potti Sriramulu’s fast for Andhra). The SRC report (1955) emphasized language but also recommended balanced reorganization for national unity. The States Reorganisation Act, 1956 reorganized India into 14 states and 6 union territories. Learning Corner: Background: India Post-Independence (1950) After the Constitution came into effect in 1950, Indian territory was categorized into: Part A States: Former British provinces (e.g., Bombay, Madras) Part B States: Former princely states (e.g., Hyderabad, Mysore) Part C States: Chief Commissioner’s provinces (e.g., Delhi, Himachal Pradesh) Part D State: Andaman & Nicobar Islands This structure was temporary and inefficient, prompting demands for reorganization, especially on linguistic lines. Major Movements and the First Linguistic State (1953) Demand for linguistic states gained momentum, especially among Telugu, Marathi, Tamil, and Kannada speakers. The death of Potti Sriramulu after a hunger strike led to the formation of Andhra State (1953) from the Telugu-speaking areas of Madras. Key Committees on Reorganization Committee Year Members Key Recommendations Dhar Commission 1948 S.K. Dhar (Chairman) Opposed reorganization solely on linguistic lines; favored administrative convenience. JVP Committee 1949 Jawaharlal Nehru, Vallabhbhai Patel, Pattabhi Sitaramayya Rejected linguistic states initially; favored national unity over linguistic aspirations. States Reorganisation Commission (SRC) 1953 Fazl Ali (Chairman), K.M. Panikkar, H.N. Kunzru Recommended reorganization primarily on linguistic lines, with a focus on administrative viability and national integration. States Reorganisation Act, 1956 Based on SRC recommendations: Abolished the A/B/C/D classification. Created 14 states and 6 Union Territories. Realigned boundaries largely on linguistic basis. Subsequent State Formations and Changes Year Reorganization 1960 Bombay split into Maharashtra (Marathi) and Gujarat (Gujarati). 1966 Punjab reorganized to form Haryana (Hindi), with Chandigarh as UT. 1971-72 Manipur, Tripura, and Meghalaya became full-fledged states. 1987 Goa, Arunachal Pradesh, Mizoram became states. 2000 Creation of Chhattisgarh (from MP), Uttarakhand (from UP), Jharkhand (from Bihar). 2014 Telangana formed as India’s 29th state, bifurcated from Andhra Pradesh.

rchives (PRELIMS  Focus) Depreciation of Rupees Category: ECONOMICS Context:  The rupee recorded its biggest single-day fall in nearly 3 months, depreciating by 61 paise to close at ₹87.42 per USD. Cause: Trump Tariff Announcement: US President Donald Trump warned of 20–25% tariffs on Indian goods. Month-end dollar demand. Aggressive FPI selling. Market Reaction: Rupee fell sharply after touching an intraday low of ₹87.66. The rupee has depreciated by 161 paise in the last 11 sessions. Contributing Factors: Fears of economic impact from new US tariffs. Heavy outflows by FPIs (₹16,370 crore in a week). Dollar demand from importers (especially oil firms). Stronger dollar globally. Learning Corner: Currency Appreciation & Depreciation: Appreciation: When the value of the Indian Rupee rises relative to foreign currencies (e.g., ₹75/USD becomes ₹70/USD). Depreciation: When the Rupee falls in value (e.g., ₹75/USD becomes ₹80/USD). Link with Inflation: Depreciation → Costlier Imports → Imported Inflation India depends heavily on oil, electronics, and capital goods imports. A weaker rupee makes these imports more expensive, leading to higher domestic prices. It fuels cost-push inflation (e.g., higher transport and input costs). Appreciation → Cheaper Imports → Helps Tame Inflation A stronger rupee reduces the import bill, especially for crude oil. It can ease inflationary pressure, particularly in sectors dependent on imported inputs. Broader Impact on Indian Economy: Aspect Depreciation of Rupee Appreciation of Rupee Exports Boosts competitiveness (positive) Hurts competitiveness (negative) Imports Becomes costlier (negative) Becomes cheaper (positive) Inflation Increases (especially WPI, CPI) May reduce inflation Current Account Deficit (CAD) May worsen May improve (if exports stay stable) Foreign Investment Can deter if seen as unstable Can attract stable flows RBI Intervention via the Forex Market: Objective: To stabilize the exchange rate of the rupee. When the Rupee Depreciates Sharply: RBI sells US Dollars from its foreign exchange reserves. This increases the supply of dollars and demand for rupees, supporting the rupee. Helps curb imported inflation (e.g., oil becomes less costly in rupee terms). When the Rupee Appreciates Excessively: RBI buys US Dollars, injecting rupees into the market. Prevents exports from becoming uncompetitive. Avoids disinflation or deflation risk due to excess appreciation. Tool Used: Spot and forward transactions, swaps, open market operations in forex. RBI Intervention via Monetary Policy: Objective: To control domestic inflation and manage capital flows. When Inflation Rises (Often Due to Depreciation): RBI may increase the repo rate (tight monetary policy). Higher interest rates attract foreign capital inflows, strengthening the rupee. Also reduces domestic demand, controlling demand-pull inflation. When Growth Slows and Inflation is Low: RBI may cut interest rates to boost credit and investment. This may lead to mild rupee depreciation, which can support exports. Tool Used: Repo rate, CRR, SLR, Open Market Operations (OMOs)   RBI Tool Purpose Impact on Rupee Impact on Inflation Selling USD Curb rupee fall Strengthens rupee Controls imported inflation Buying USD Curb excess rise Weakens rupee Boosts exports Raising Repo Rate Tame inflation Attracts FPI, strengthens rupee Controls inflation Cutting Repo Rate Boost growth May weaken rupee Mild inflation rise possible Source: THE INDIAN EXPRESS Mangroves Category: ENVIRONMENT Context: Restoring Mangroves Can Turn the Tide on India’s Coastal Security Why Mangroves Matter: Natural Barriers: Protect coastal areas from cyclones, tidal surges, and erosion. Climate Mitigation: Act as carbon sinks; trap carbon dioxide and store blue carbon. Biodiversity Hotspots: Provide habitat for fish, crabs, molluscs, and migratory birds. Cultural/Economic Value: Vital to local communities for fishing, farming, and traditional practices. Major Threats to Mangroves: Urban expansion, pollution, shrimp farming, altered hydrology, and climate change. Over 50% of mangroves globally are at risk of collapse by 2050 (IUCN report). Learning Corner: Mangroves Mangroves are salt-tolerant trees and shrubs found in coastal intertidal zones of tropical and subtropical regions. They grow in brackish water, where freshwater mixes with seawater, especially in estuaries, lagoons, and deltas. India has about 4,975 sq km of mangrove cover (as per ISFR 2021), mainly in Sundarbans, Gujarat, and Andhra Pradesh. Unique Features of Mangroves Salt Tolerance (Halophytic Nature) Survive in saline conditions through salt-excreting leaves and special root adaptations. Special Root Systems Have stilt roots, pneumatophores (breathing roots), and prop roots for oxygen absorption and anchorage in soft, waterlogged soils. Tidal Adaptability Thrive in highly dynamic tidal zones, tolerating both flooding and exposure to air. High Carbon Sequestration Store large amounts of “blue carbon” in both biomass and deep, anoxic soils  crucial for climate change mitigation. Nursery Grounds Serve as breeding and nursery habitats for fish, crabs, shrimps, and molluscs — vital for coastal livelihoods. Natural Coastal Barriers Protect shorelines from cyclones, tsunamis, storm surges, and coastal erosion. Species Diversity India hosts over 40 mangrove species, with Avicennia, Rhizophora, and Sonneratia being common genera. Ecological and Economic Significance Provide ecosystem services, such as biodiversity support, carbon storage, fisheries productivity, and livelihoods. Act as bioshields, especially in disaster-prone coastal areas like the Sundarbans and Odisha coast. Mangrove Cover in India by State/UT (Descending Order): Rank State/UT Mangrove Area (sq km) % of India’s Total Mangrove Cover Key Mangrove Regions 1 West Bengal 2,114 42.3% Sundarbans (World’s largest mangrove delta) 2 Gujarat 1,141 23.6% Gulf of Kutch, Gulf of Khambhat 3 Andaman & Nicobar Islands 617 12.3% North, Middle & South Andaman coastlines 4 Andhra Pradesh 404 8.1% Godavari and Krishna estuaries 5 Maharashtra 304 6.4% Thane Creek, Raigad, Ratnagiri 6 Odisha 251 5.0% Bhitarkanika delta 7 Tamil Nadu 45 1.0% Pichavaram, Muthupet 8 Goa 26 0.5% Mandovi and Zuari river estuaries 9 Kerala 9 0.2% Kannur, Kozhikode estuaries 10 Karnataka 3 0.1% Uttara Kannada coast Total Mangrove Area in India: 4,975 sq km (approx. 0.15% of total geographical area) Source:  THE HINDU Kamchatka Quake Category: GEOGRAPHY Context : A massive 8.8 magnitude earthquake struck Russia’s Kamchatka Peninsula, one of the strongest in recent times. What Happened? It occurred on the Circum-Pacific Seismic Belt (Ring of Fire), which accounts for 80% of the world’s strongest quakes. Triggered a tsunami with waves up to 3–4 metres in parts of Kamchatka and up to 2 feet in Hawaii. No casualties were reported

rchives (PRELIMS  Focus) Gini Index Category: ECONOMICS Context:  The Gini Index ranked India among the world’s more equal societies It fails to capture ground-level realities of urban-rural, gender, wealth, and digital inequalities. Its methodology overlooks informal sector employment, access disparities, and social norms that perpetuate inequality. Forms of Inequality in India: Wealth Inequality: A small fraction holds most of the nation’s wealth. The top 10% own a disproportionate share of income. Informal jobs and non-taxable income make wealth inequality hard to quantify. Gender Inequality: Women make up only 35.9% of the workforce. Only 12.7% of leadership roles are held by women. Startups founded by women are just 7.5% of the total. Patriarchal norms result in fewer resources for girl children and less inheritance. Digital Inequality: Only 53.9% of schools have Internet, and 52.7% have functional computers. Only 25% of rural women vs 49% of rural men have internet access. School closures during pollution seasons show how unequal internet access affects education. Learning Corner: Gini Coefficient The Gini Coefficient (or Gini Index) is a statistical measure of income or wealth inequality within a population. Definition: It ranges from 0 to 1 (or 0% to 100%): 0 represents perfect equality (everyone has the same income). 1 represents perfect inequality (one person has all the income, others have none). How It’s Measured: Based on the Lorenz Curve, which plots the cumulative share of income against the cumulative share of the population. The Gini Coefficient is the ratio of the area between the line of equality and the Lorenz curve to the total area under the line of equality. Applications: Used globally by economists, policymakers, and institutions like the World Bank and UNDP to assess income distribution. Helps compare inequality across countries or over time. Limitations: Does not capture non-income inequalities (e.g., gender, digital access). Insensitive to the location of inequality (whether at the top or bottom of the income scale). Similar Gini scores may mask very different economic structures.

Learning Corner: Oilseeds Production in India: India is one of the largest producers of oilseeds globally but remains a net importer of edible oils, meeting over 50% of its domestic demand through imports. Major oilseeds grown include: Groundnut, Soybean, Mustard/Rapeseed, Sunflower, Sesame, Linseed, Niger, Safflower, and Castor. Cultivated mainly in rain-fed areas; productivity is often lower due to climate variability, low input use, and limited irrigation. Key Government Schemes: National Mission on Edible Oils – Oilseeds (NMEO–Oilseeds) (2024–25 to 2030–31) Aims to make India self-reliant in edible oils. Targets to increase oilseeds production to 69.7 million tonnes by 2030–31. Key components: High-yielding seeds, climate-resilient varieties Financial incentives, input subsidies Crop insurance, SATHI portal for seed coordination Post-harvest management and value addition Focus on both primary and secondary sources (e.g., rice bran, cottonseed) National Food Security Mission (NFSM – Oilseeds & Oil Palm) Promotes productivity and area expansion for oilseed crops. Provides financial support for inputs, training, and cluster demonstrations.

Source:  PIB Ladakh’s hot springs Category: GEOGRAPHY Context : Ladakh’s hot springs and the origin of life Why They Matter: Unique Carbonate Chemistry: Unlike global focus on silica, Ladakh’s hot springs (notably in Puga Valley) show rapid calcium carbonate (travertine) formation, which preserves organic molecules like amino acids and fatty acids—key to prebiotic chemistry. Natural Laboratory: These springs offer a real-world setting resembling early Earth, ideal for studying how life might have formed. Extremophile Insights: Harsh conditions (UV radiation, temperature extremes) mirror early Earth and Mars. Microbes here produce protective substances, offering clues to how life adapts and survives in extreme environments. Astrobiological Significance: Mars Analog: Similarities to Martian hydrothermal systems make Ladakh valuable for space science. Biomarker Clues: Helps identify where and how to search for biosignatures on Mars, guiding missions by ISRO and NASA. Key Takeaways: Carbonates are crucial for preserving life’s building blocks. Supports new directions in astrobiology, synthetic biology, and Mars exploration. Strengthens India’s contribution to the search for life beyond Earth. Learning Corner: Hot Springs: Definition: A hot spring is a natural discharge of geothermally heated groundwater at the Earth’s surface. Formed when groundwater seeps deep into the Earth, gets heated by magma or hot rocks, and rises back to the surface. Temperatures can vary — from lukewarm to boiling. Found in tectonically active regions, especially volcanic zones. Notable Indian examples: Manikaran (Himachal Pradesh) Tapovan (Uttarakhand) Bakreshwar (West Bengal) Geysers: A geyser is a special type of hot spring that erupts periodically, shooting steam and hot water into the air. Occur when pressure builds in underground chambers filled with boiling water and steam. Require: Intense geothermal heat Abundant groundwater A unique plumbing system with narrow conduits Much rarer than hot springs. Famous geysers: Old Faithful in Yellowstone National Park (USA) El Tatio in Chile No significant true geysers in India.
