GS Paper: GS3

  • What is wetland? Explain the Ramsar concept of ‘wise use’ in the context of wetland conservation. Cite two examples of Ramsar sites from India.

    As per Ramsar Convention, wetlands are defined as “areas of marsh, fen, peatland or water, whether natural or artificial, permanent or temporary, with water that is static or flowing, fresh, brackish or salt, including areas of marine water the depth of which at low tide does not exceed six metres”.

    Ramsar Concept of Wise Use

    It refers to the maintenance of ecological character of wetlands through sustainable use, ensuring that benefits derived from wetlands do not lead to long-term degradation.

    Recently, India’s resolution on the ‘‘Promoting Sustainable Lifestyles for the Wise Use of Wetlands’’ was adopted at the 15th COP15 to the Ramsar Convention on Wetlands.

    Key Elements of Wise Use

    Maintaining Ecological Character – Conservation of hydrology, biodiversity, water quality, and ecosystem services. Eg – Preventing encroachment and regulating land-use.

    Integrated Management Approach – Eg – Wetland Management Committees under Wetlands (Conservation and Management) Rules, 2017.

    Avoiding Degradation – Ensuring human activities do not cause pollution, over-extraction, or habitat loss. Eg – Restricting construction and waste discharge around wetlands.

    Sustainable Livelihoods – Supporting communities dependent on wetlands while ensuring ecological health. Eg – regulated fisheries in Ramsar sites.

    Examples of Ramsar Sites in India

    India has 94 Ramsar Sites (highest in Tamil Nadu)

    Keoladeo National Park (Rajasthan)

    A UNESCO World Heritage Site

    Important for migratory birds like Siberian cranes; supports floodwater-based wetland ecology.

    Chilika Lake (Odisha)

    Asia’s largest brackish water lagoon

    Known for Irrawaddy dolphins, rich fisheries, and large wintering bird populations.

    Wetlands are critical natural infrastructure and the Ramsar principle of wise use ensures that development and conservation are balanced.

  • Sikkim is the first ‘Organic State’ in India. What are the ecological and economical benefits of Organic State?

    Sikkim became the world’s first fully organic state in 2016, eliminating synthetic chemical fertilisers and pesticides across all cultivated land.

    Ecological benefits of an Organic State

    Use of compost, green manure and bio-fertilisers increases soil organic carbon, microbial activity and soil structure.

    Biodiversity conservation – Absence of chemicals protects pollinators and native flora.

    No nitrate and phosphate runoff – improve river and groundwater quality.

    Low carbon footprint – Cuts GHG emissions linked to synthetic fertiliser production and use.

    Climate resilience – Better soil moisture retention enhance tolerance to droughts

    Natural pest control through Crop rotation, intercropping and biological agents

    Erosion control in hills – Mulching, agroforestry and contour cultivation reduce topsoil loss

    Prevents bioaccumulation of harmful chemicals in food chains.

    Economic benefits of an Organic State

    Premium price – Organic certification gives higher market value in domestic and export markets

    Reduced input costs on chemical fertilisers and pesticides.

    Higher net income despite moderate yields due to Lower production cost + premium price.

    Boost to agri-tourism and eco-tourism creating secondary income– Eg- ‘Sikkim Organic’ brand attracts green tourists and researchers

    Export potential – High-demand products like large cardamom, ginger, turmeric, kiwi, vegetables and orchids.

    Employment generation in composting, certification, packaging, processing and value-addition

    Long-term productivity stability – Healthy soil ensures sustained yields over time, avoiding chemical dependency traps.

    Budget 2025-26 emphasised Agriculture as the ‘first engine’ for India’s development journey. Organic Farming can be the ‘sustainability pillar’ of this journey.

  • The China-Pakistan Economic Corridor (CPEC) is viewed as a cardinal subset of China’s larger ‘One Belt One Road’ initiative. Give a brief description of CPEC and enumerate the reasons why India has distanced itself from the same.

    The CPEC is a flagship connectivity and infrastructure project linking China’s Xinjiang province to Pakistan’s Gwadar port through roads, railways, pipelines and industrial zones.

    Description of CPEC

    Around 3,000 km corridor from Kashgar (China) to Gwadar (Pakistan).

    Investment Scale – over USD 60 billion across energy, transport and industrial sectors.

    Infrastructure Focus – Roads, railways, ports, power plants and Special Economic Zones.

    Solves ‘Malacca Dilemma’ of China – Provides access to the Arabian Sea, bypassing the Malacca Strait.

    It is the link between the Silk Road Economic Belt and the Maritime Silk Road.

    Reasons behind India distanced itself from CPEC

    Strategic Encirclement Concerns (String of Pearls) – Eg- Chinese control and presence at Gwadar port.

    Military and Security Implications – Dual-use infrastructure can support Chinese naval and military operations.

    Economic Non-Viability – India has concerns regarding the “debt trap” nature of BRI projects. Eg- Sri Lanka’s Hambantota port experience.

    Lack of Transparency and Consultation – CPEC and BRI lack open, multilateral consultation and standardised norms.

    Undermines Rules-Based International Order – Projects ignore environmental, social and legal standards.

    Geo-Strategic Marginalisation – Expansion of CPEC into Afghanistan could undermine India’s alternative connectivity initiatives like Chabahar Port and the INSTC.

    Due to CPEC, China may emerge as a ‘direct party’ in the Kashmir dispute in future.

    As Robert Kaplan observes, “Geography is the canvas on which history is painted.” By opposing CPEC, India seeks to uphold a rules-based approach to regional integration.

  • What are the impediments in disposing the huge quantities of discarded solid wastes which are continuously being generated? How do we remove safely the toxic wastes that have been accumulating in our habitable environment?

    According to a report by TERI, India generates 62 million tonnes (MT) of waste annually. Only 43 MT of total waste gets collected and 12 MT treated before disposal.

    Impediments in Disposing Huge Quantities of Solid Waste

    Rapid Urbanisation – Cities generate waste faster than civic bodies can manage. Eg – Cities produce 160,000+ tonnes/day of solid waste.

    Inadequate Segregation at Source – makes recycling and composting inefficient.

    Limited Treatment & Processing Capacity – Only 50% of the waste produced is actually processed in India. (CPCB)

    Dumping in Landfills – Eg – Ghazipur and Deonar operate beyond capacity.

    Dominance of Informal Sector – Eg- 80% of plastic collection relies on the informal sector – lack safety mechanisms

    Poor compliance with Solid Waste Management Rules, 2016. Eg – Many ULBs still rely on open dumping.

    Lack of data transparency – Eg- according to the official estimates, plastic waste generation rate in India is 0.12 kg/capita/day, while as per ‘Nature’ , it is 0.54 kg/capita/day.

    Limited capacity of ULB’s – Lack 3Fs and functional overlap with parastatal bodies

    Inadequate Infrastructure for waste collection, segregation, transportation, processing, and disposal.

    Lack of Interagency co-ordination – Eg- MoEFCC develop rules and guidelines while the Ministry of Housing and Urban Affairs oversees ground-level enforcement

    Safe Removal of Toxic Wastes from the Environment

    Technology adoption – Eg – Biomedical waste treated using controlled incinerators.

    Smart Waste Management System using AI, IoT. Eg- RFID-enabled door-to-door waste collection monitoring

    Promoting circular economy based on 6R principle – Refuse, Rethink, Reduce, Reuse, Repair, and Recycle

    Promoting Composting, vermicomposting and bio-methanation for treating organic waste.

    Enhanced Public-Private Partnerships – Eg- contractual arrangement with the private sector for setting up compost plants.

    Decentralised Waste Processing – Eg- Micro-Composting Centres (MCC) with 5 TPD capacity for wet waste.

    Adopting Waste Hierarchy principle

    Strict implementation of ‘Polluter Pays Principle‘, to penalize non-compliance and shift towards ‘Government Pays Principle’

    Efficient waste management is not just a regulatory obligation but a constitutional imperative to safeguard the fundamental rights of citizens.

  • Discuss the work of ‘Bose-Einstein Statistics’ done by Prof. Satyendra Nath Bose and show how it revolutionized the field of Physics.

    In 1924, S.N Bose wrote a groundbreaking paper on quantum theory that solved key problems in radiation physics. Recognizing its importance, Albert Einstein translated and published it, laying the foundation of Bose-Einstein statistics and modern quantum mechanics.

    The Work of ‘Bose-Einstein Statistics’

    Indistinguishability of Particles: Bose proposed that subatomic particles like photons are completely identical and indistinguishable, meaning swapping their positions does not create a new physical state.

    New Counting Method: Instead of using classical probability, Bose developed a unique statistical method to calculate how identical particles distribute themselves across different energy levels.

    Deriving Planck’s Law: Bose successfully derived Max Planck’s blackbody radiation formula purely from quantum concepts, completely removing the traditional reliance on classical physics electromagnetism laws.

    Integer Spin Behavior: The statistics apply to particles with whole-number spins, called Bosons, which naturally tend to cluster together in the exact same quantum state.

    Extension to Matter: Albert Einstein expanded Bose’s mathematical framework from light photons to massive gas atoms, predicting a new state of matter at ultra-low temperatures.

    How It Revolutionized the Field of Physics

    The Concept of Bosons: Particles with integer spins (Eg- photons, gluons, and the Higgs Boson) were named bosons in his honor. Unlike fermions, any number of bosons can occupy the same quantum state.

    Macroscopic Quantum Phenomena: The statistics provided the mathematical basis to understand low-temperature quantum phenomena like superfluidity and superconductivity.

    Experimental Proof: The theoretical prediction of BECs was experimentally proven in 1995 by Eric Cornell and Carl Wieman, which created an entirely new field of ultra-cold atomic physics.

    Technological Applications: It serves as the underlying principle behind lasers (which rely on coherent, indistinguishable photons), semiconductors, and modern quantum computing

    S.N Bose bridged the gap between early quantum theory and modern quantum mechanics by redefining particle identity through revolutionary statistical methods, influencing pioneers like Erwin Schrödinger and Werner Heisenberg.

  • Assess the role of National Horticulture Mission (NHM) in boosting the production, productivity and income of horticulture farms. How far has it succeeded in increasing the income of farmers?

    The NHM was a centrally sponsored scheme launched in 2005-06 to promote the holistic development of the horticulture sector through area-based, regionally differentiated strategies.

    Key Pillars of NHM

    Cluster based approach

    Supply of quality planting material through nurseries and tissue culture units.

    Improving production and productivity through area expansion and rejuvenation.

    Promoting and spreading modern technologies.

    Focussing on training and skill development.

    Infrastructure for post-harvest management and marketing.

    Role of NHM in boosting

    Production

    Horticulture production increased from 280.70 MT (2013-14) to 367.72 MT (2024-25) (Fruits: 114.51 MT, Vegetables: 219.67 MT)

    Fruit production increased by ~30%, and vegetable production increased by ~22%.

    Establishment of nurseries and tissue culture units ensured healthy, disease-free plants.

    Area-focused interventions increased scale and concentration of production.

    Crop diversification – Promotion of high-value and short-duration crops.

    Boost in Productivity

    The productivity has risen from 12.10 MT per hectare in 2019 to 12.56 MT per hectare in 2024

    Distribution of high-yielding and disease-resistant varieties increased output per unit area.

    Technology dissemination – Promotion of drip irrigation, mulching, protected cultivation (polyhouse, net house).

    Farmers trained in scientific cultivation, pest control and nutrient management – improved efficiency.

    Reduced crop loss through improved plant health and management practices.

    Boost in Farmer Income

    Horticulture now contributes about 33% to Agriculture Gross Value Added (GVA) in Agriculture.

    High-value crops – Fruits, spices and flowers generate more income per hectare than cereals.

    Multiple cropping cycles of Vegetables and floriculture ensure regular cash flow.

    Post-harvest infrastructure – Cold storage, pack houses, grading and processing units reduce wastage and increase price realisation.

    Export potential –

    Employment generation – Jobs in nurseries, processing, transport and storage supplement household income.

    Challenges

    Uneven regional performance – Benefits concentrated in better-developed states/regions

    Low Exports – India ranks 14th in vegetables and 23rd in fruits, and its share in the global horticultural market is a mere 1%.

    Input issues –

    less than 5% of Indian soils have sufficient nitrogen

    Only 55% area irrigated.

    Seed replacement rate is 35-45% (over 90% in USA)

    Inadequate cold-chain and logistics – Around 15-20% of the fruits and vegetables in India are wasted

    Climate vulnerability – Sensitive to droughts, floods, heat waves, pests. Eg- Locust Attack

    Sanitary and Phytosanitary (SPS) barriers – Eg- rejection of consignments by EU due to pesticide residue detection.

    Way Forward

    Agro-ecological approach – District-Level Climate-Contingent Crop Planning Cells

    Rural Agri-Logistics Nodes under Gati Shakti Framework to develop cold chains, aggregation centers

    Strengthening FPOs to enhance collective bargaining and direct market access for farmers. Eg- Sahyadri FPO in Maharashtra – increased incomes by 30%

    Raising R&D Investment to 1% of GDP

    Legal Reforms – Simplify land leasing laws, Adopt model contract farming Act

    Budget 2025-26 emphasised Agriculture as the ‘first engine’ for India’s development journey. Horticulture can be the key pillar of this journey.

    Farm Subsidy and Minimum Support Prices

  • Examine the role of supermarkets in supply chain management of fruits, vegetables and food items. How do they eliminate number of intermediaries?

    Supermarkets are organised retail chains that procure, store and distribute fruits, vegetables and other food items through integrated, modern supply chains.

    Role of Supermarkets in supply chain management

    Direct Procurement from Farmers – Eg- Big Basket & Reliance Retail procure directly from FPOs.

    Standardisation, Grading & Sorting improves quality consistency. Eg- Walmart trains farmers on GAP (Good Agricultural Practices).

    Efficient Logistics & Inventory Management – Eg- use of real-time inventory tracking, forecasting tools, barcoding/RFID

    Cold Chain infrastructure reduces losses of perishable goods like fruits

    Contract Farming, buy-back arrangements ensure stable demand and price security for farmers. Eg- PepsiCo in Punjab (Potato farming)

    Value Addition – Supermarkets invest in cut vegetables, ready-to-cook items etc – increases shelf-life of products.

    Diverse products– Gives greater choice for consumers and promotes crop diversification.

    Challenges faced by supermarkets

    Lack of infrastructure – Eg- cold storage can only accommodate about 11% of the country’s total produce.

    Poor forward and backward linkages – Eg- Only 13% mandis digital.

    Fragmented landholdings – 86% farmers are small and marginal – prevents economy of scale

    Regulatory Hurdles – APMC monopoly and interstate movement regulations complicate direct buying from farmers.

    Organised retail remains concentrated in metro and Tier-1 cities, with limited rural coverage

    Low investment – Private investment <1% Agri-GDP.

    Supermarkets eliminating intermediaries

    Enhancing efficiency of supply chain and doubling farmers income requires FPO strengthening, cold-chain expansion and adoption of Model contract Farming Act.

  • How has the emphasis on certain crops brought about changes in cropping patterns in recent past? Elaborate the emphasis on millets production and consumption.

    A cropping pattern is the distribution of various crops within a specific area at a given time. Though the rice-wheat system became the backbone of Indian agriculture after the Green Revolution, in recent years India’s cropping pattern has moved towards diversification and high-value crops.

    Emphasis on certain crops – changing cropping pattern

    Dominance of rice-wheat in Green Revolution regions – account for over 75% of GCA in Punjab & Haryana

    Shift from food crops to commercial crops- Area under commercial crops increased from 30.4 million ha (2000-01) to 41.2 million ha (2022-23)

    Expansion of sugarcane due to ethanol policy- increased from 285 MT (2010-11) to 405 MT (2022-23)

    Rise in horticulture crops – Eg- In 2022-23, fruits and vegetables accounted for 28.3% of the Gross Value Output, surpassing cereals

    Expansion of oilseeds under National Mission on Edible Oils- increased from 25 MT (2010-11) to 41 MT (2022-23)

    Growth of organic farming- 2.9 million hectares under organic farming, highest globally. Eg- Sikkim fully organic

    Climate change impact on crop choice- Eg- 14% decline in sugarcane area in Marathwada (2015-2023) due to water stress

    Commercialisation and mechanisation- BT cotton covers 95% of cotton area, promoting

    Emphasis on millet production

    Total millet production: 180.15 lakh tonnes in 2024-25 (Increase of 4.43 lakh tonnes)

    Millet exports (2024-25): 89,164.96 tonnes worth $37 million

    MSP for Ragi (2025-26): Second highest absolute MSP increase among crops

    Policy focus

    National Millet Mission

    NFSM – Nutri Cereals

    International Year of Millets 2023 (India-led)

    Branding as Shree Anna

    Increase in millet exports

    1.5 million tonnes exported in 2023

    50% increase over 2022

    Climate-resilient nature – Drought resistant, low water, heat tolerant

    Expansion in dryland states – Increased area in Rajasthan, Karnataka, Telangana, MP, Maharashtra

    Emphasis on millet consumption

    Rising health consciousness

    High in iron, calcium, fibre and protein

    Helpful against diabetes & malnutrition

    Improvement in nutrition security – Reduces hidden hunger and micronutrient deficiency

    Inclusion in government schemes – PDS, Mid-Day Meal, ICDS, Anganwadi

    Urban & processed food demand – Used in biscuits, noodles, bakery & breakfast foods

    MSME & startup growth – Eg- “Millet Challenge” for startups,, with a seed grant of Rs 1 crore each to three winners.

    Policy and market-driven emphasis on selected crops is transforming India’s cropping pattern, with millets emerging as a sustainable pillar of nutrition and livelihood security.

  • What do you mean by Minimum Support Price (MSP)? How will MSP rescue the farmers from the low-income trap?

    MSP is the government-declared assured floor price at which the government procures specific agricultural crops from farmers, through agencies like FCI, NAFED and state procurement bodies.

    Announced before the sowing season based on recommendations of the Commission for Agricultural Costs and Prices (CACP)

    Intended to cover the cost of production + reasonable margin (50% over A2+FL cost)

    Notified for 23 crops (22 mandated crops andFRP for sugarcane)

    Role of MSP in rescuing farmers from the Low-Income Trap

    Predictability – Assured pricing helps farmers plan crop investments, buy better inputs and adopt new technologies.

    Crop diversification through higher MSPs for nutri-cereals and oilseeds. Eg- higher MSP hikes for millets in recent years

    Improved creditworthiness of farmers due to MSP-backed income – Reduce dependence on moneylenders.

    Enhances Food Security through the Public Distribution System (PDS)

    Strengthens Rural Economy – higher rural demandmultiplier effect on rural economy

    Benchmark for private buyers: If traders offer prices below MSP, farmers can opt to sell to government agencies instead.

    Limitations of MSP

    Effective mainly for wheat and rice in states like Punjab, Haryana, MP, UP

    MSP growth has not kept pace with rising production costs. (CRISIL Report)

    Limited Reach – only 6% farmers benefitted (Shanta Kumar committee)

    94% of the total agri and allied sector output is outside MSP support.

    Limited storage capacity has resulted in huge piling of stocks in FCI warehouses.

    Way Forward

    Shift towards Regenerative Agriculture Incentives – Eg- DBT for farmers adopting soil-friendly inputs, micro-irrigation, and low-carbon practices

    Price Deficiency Payment (MP’s Bhavantar Bhugtan Yojana)

    MSP 2.0 based on 3 D’s – Decentralisation, Diversification and Digital Procurement.

    MSP can act as a meaningful income stabiliser only when it is complemented by efficient procurement, strong market linkages, and inclusive access

  • Comment on the important changes introduced in respect of the Long term Capital Gains Tax (LCGT) and Dividend Distribution Tax (DDT) in the Union Budget for 2018-2019.
