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. Source: THE HINDU Atmanirbhar Oil Seeds Abhiyan Category: POLITY Context: Launched in 2024-25, this mission aims to make India self-reliant in oilseed and edible oil production by 2030-31 Key Objectives: Achieve self-sufficiency in key oilseeds like mustard, soybean, groundnut, sunflower, sesame, and others. Enhance research in high-yield, climate-resilient varieties. Promote modern farming practices and digital technologies. Provide financial incentives and input subsidies. Strengthen post-harvest management, market linkages, and processing infrastructure. Expand crop insurance coverage. Boost secondary oil extraction from sources like rice bran, cottonseed, and tree-borne oilseeds. Implementation & Targets: Duration: 2024-25 to 2030-31 Budget: ₹10,103 crore Target: Raise oilseed production from 39 to 69.7 million tonnes Goal: Meet 72% of projected domestic edible oil demand Support Measures: Launch of SATHI portal for seed supply coordination. Increased MSP and schemes like PM-AASHA to ensure fair pricing. Higher import duties to protect domestic producers. Emphasis on environmental sustainability and rural employment. 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. Price Support Scheme (PSS) Under PM-AASHA, ensures Minimum Support Price (MSP) procurement for oilseeds by government agencies. Rashtriya Krishi Vikas Yojana (RKVY) A flexible scheme to fund state-led initiatives, including support for oilseeds based on local needs.

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. Geological Importance: Indicators of geothermal energy potential Support unique microbial ecosystems Sites of tourism and religious importance Source:  PIB Pralay missile Category: SCIENCE
