  • [5th June 2025] The Hindu Op-ed: Aiming for an era of ‘biohappiness’ in India

    PYQ Relevance:

    [UPSC 2024] Explain the role of millets for ensuring health and nutritional security in India.

    Linkage: In this article, discuss how millets, classified as Neglected and Underutilized Species (NUS) and now as “opportunity crops,” are nutritionally dense and climate-resilient. This question directly aligns with the core components of ‘biohappiness’ that emphasize “nutrition security” and bringing “forgotten foods back to the table”.

     

    Mentor’s Comment:  India’s traditional food habits, especially in tribal and rural areas like Arunachal Pradesh, are at risk because many local plants and crops are disappearing. This loss is not just about rare plants but also about losing foods that are nutritious, climate-resilient, and hold cultural importance, along with the traditional knowledge that supports them.

    Today’s editorial will talk about the quick loss of biodiversity and traditional food knowledge in India. It will help with GS Paper II (Policy Making) and GS Paper III (Agriculture & Environment).

    _

    Let’s learn!

    Why in the News?

    The fast loss of biodiversity and food knowledge, caused by cash crops, global diets, and weak policies, urges India to use new science and revive orphan crops (Neglected and Underutilized Species) like millets for better food and environment.

    What are Neglected and Underutilized Species (NUS)?

    • NUS are traditional crops like millets, legumes, tubers, and wild fruits that have been largely ignored or underused in modern agriculture and food systems.
    • These species are nutritionally rich, climate-resilient, and well-adapted to local environments, offering potential to improve food security and support sustainable farming.

    Why are they now referred to as “opportunity crops”?

    • Nutritionally Dense: These crops are rich in essential nutrients, vitamins, and minerals, making them excellent for improving health. Eg: Small millets are high in fiber and micronutrients compared to rice and wheat.
    • Climate-Resilient: They can withstand harsh environmental conditions like drought and poor soils, helping farmers adapt to climate change. Eg: Finger millet (ragi) grows well in dry and marginal lands.
    • Locally Adapted: These crops are naturally suited to local soils and climates, reducing the need for chemical fertilizers and irrigation. Eg: Buckwheat thrives in the hilly regions of Northeast India without intensive inputs.
    • Support Biodiversity: Cultivating these crops preserves agrobiodiversity and traditional farming knowledge, maintaining ecological balance. Eg: Indigenous legumes help fix nitrogen in soil, improving fertility naturally.
    • Economic Potential: Reviving these crops can create new market opportunities, increase farmers’ incomes, and diversify food production. Eg: Millet-based products are gaining popularity in urban markets for their health benefits.

    Why is agrobiodiversity declining in Northeast India?

    • Rapid Disappearance of Traditional Plants: Many native plant species are disappearing quickly due to changing land use and environmental pressures. Eg: Traditional greens and wild fruits once common in Arunachal Pradesh are becoming rare.
    • Loss of Traditional Knowledge: Indigenous knowledge about the nutritional and medicinal properties of local plants is being lost as younger generations move away from traditional lifestyles. Eg: Nyishi and Apatani tribes’ understanding of forest plants is fading.
    • Shift to Commercial Crops: Farmers are moving from diverse local crops to cash crops for better income, reducing crop variety. Eg: In Kolli Hills, many farmers switched from millets to coffee and pepper.
    • Environmental Changes and Species Extinction: Habitat loss and climate change are causing a rise in species extinction, mirroring a global trend. Eg: Forest degradation in Northeast India is threatening native biodiversity.
    • Lack of Awareness and Support: There is limited awareness and institutional support for conserving local agrobiodiversity, leading to neglect. Eg: Many minor millets remain neglected in government schemes despite their benefits.

    Where has millet revival been successfully implemented?

    • Kolli Hills, Tamil Nadu: The M.S. Swaminathan Research Foundation (MSSRF) has worked with local farmers for over 20 years to prevent millet diversity loss. Efforts include documenting traditional knowledge, improving soil health, diversifying crops, and enhancing income, especially among women farmers. Eg: Farmers shifted back from cash crops to locally adapted millets.
    • Koraput District, Odisha: Collaboration with the Odisha Millet Mission has supported a community-led millet revival, focusing on seed conservation to consumption, expanding the range of millets beyond the commonly promoted ragi, jowar, and bajra. Eg: Minor millets are being reintroduced into local diets and markets.

    How does a few crops’ dominance affect global nutrition?

    • Over-Reliance on Few Crops: Global food systems mainly depend on rice, wheat, and maize, which provide over 50% of plant-based calories. This limits dietary diversity. Eg: Many populations rely heavily on rice, leading to monotonous diets.
    • Loss of Biodiversity: Dominance of a few crops causes a decline in agricultural biodiversity, reducing availability of diverse nutrients. Eg: Traditional millets and legumes are neglected, despite being nutrient-rich.
    • Nutritional Imbalances: Diets based on a limited number of staple crops can cause deficiencies in vitamins, minerals, and proteins. Eg: Populations depending mainly on wheat may face iron and zinc deficiencies.
    • Vulnerability to Climate Shocks: Dependence on few crops makes food systems more susceptible to climate change impacts, threatening food security. Eg: Droughts affecting maize crops can lead to widespread shortages.
    • Rise in Non-Communicable Diseases: Limited crop diversity correlates with an increase in diseases like diabetes and obesity, due to poor diet quality. Eg: High consumption of refined wheat and maize products contributes to obesity trends.

    What are the steps taken by the Indian government? 

    • International Year of Millets & Shree Anna Yojana: Launched focused strategies to enhance millet production, productivity, consumption, and export, while raising awareness about health benefits.
    • State Millet Missions: Several states have started their own Millet Missions to support local cultivation, value chain strengthening, and branding of millets.
    • Inclusion in Public Distribution System (PDS): Efforts are underway to include minor millets in the PDS to promote wider access and consumption among the population.

    Way forward: 

    • Expand Millet Coverage and Integration: Broaden the focus beyond major millets (ragi, jowar, bajra) to include minor millets and other neglected crops in state missions and the Public Distribution System (PDS) for greater reach and impact.
    • Strengthen Farmer Empowerment and Research: Support community-led conservation, improve value addition technologies, and invest in interdisciplinary researchto enhance crop resilience, nutritional value, and market opportunities.

  • Rising ‘Black Carbon’ heating Himalayan Snow: Study

    Why in the News?

    A recent study by the think-tank Climate Trends has revealed that levels of black carbon in the Himalayas have been rising steadily over the past two decades.

    About Black Carbon (BC):

    • What is it: Black carbon is a fine particulate pollutant formed from the incomplete combustion of biomass and fossil fuels.
    • Impact: It is a short-lived climate pollutant and the second-largest contributor to global warming after carbon dioxide.
    • Lifespan: Unlike CO₂, black carbon stays in the atmosphere for short periods and can be quickly reduced if emissions stop.
    • Warming Mechanism: As an aerosol, it absorbs sunlight, heats the atmosphere, and reduces albedo when deposited on snow and ice, leading to faster melting.
    • Health Effects: Exposure increases the risk of heart disease, birth complications, and premature death.
    • Major Sources in India:
      • Residential Biomass Burning: Accounts for 47% of BC emissions, including cow dung and straw burning.
      • Industries and Vehicles: Industries contribute 22%, while diesel vehicles add 17%.
      • Other Sources: Open burning contributes 12%, and other minor sources 2%.
      • High-Emission States: Madhya Pradesh and Maharashtra are major emitters due to agricultural and forest fires.
      • Biofuel Usage: Alone contributes nearly 42% of India’s total BC emissions.

    Key Findings from the Study (2000–2023):

    • Snow Temperature Rise: Himalayan snow surface temperature rose from -11.27°C to -7.13°C over two decades.
    • Regional Trends: The Eastern Himalayas were warmest, followed by the Central and Western regions.
    • BC Influence: Deposits of black carbon lower snow reflectivity, increase heat absorption, and accelerate glacier melt.
    • Population Risk: Glacier loss threatens the freshwater supply for nearly 2 billion people downstream.
    • Increase in Snow Depth: Despite warming, average snow depth rose from 0.059 m to 0.117 m.
    • Reasons: This is due to more snowfall, changing precipitation, and wind redistribution.
    • Regional Comparison: The Western Himalayas showed highest snow depth, linked to elevation and winter storms, while the Eastern and Central Himalayas had less snow due to proximity to BC sources.

  • Building-Integrated Photovoltaics: converting buildings into solar assets 

    Why in the News?

    India’s rooftop solar (RTS) capacity has gone beyond 17 GW, showing good progress in using clean energy in cities. But in crowded urban areas, there isn’t enough space for more rooftop solar panels.

    What is Building-Integrated Photovoltaics (BIPV)?

    BIPV refers to the integration of photovoltaic materials directly into the building envelope (e.g., façades, roofs, windows). It serves both as a building material and a solar power generator. Eg: Façades, curtain walls, glass windows, skylights, tiles, railings, balconies, canopies, atriums, and shading devices.

    How does it differ from traditional rooftop solar systems?

    Traditional Rooftop Solar (RTS) Building-Integrated Photovoltaics (BIPV)
    Installation Added onto rooftops Embedded into building structure
    Space Use Limited to rooftop area Uses entire building envelope (walls, windows etc.)
    Aesthetic Usually visible, can affect aesthetics Customisable, aesthetically integrated
    Function Only generates electricity Generates electricity + serves as a building material
    Retrofitting Often retrofitted Typically integrated during design/build phase

    Why is BIPV particularly important for densely populated urban areas in India?

    • Limited Rooftop Space in High-Rises: In densely populated cities, tall buildings with small rooftops cannot accommodate large rooftop solar (RTS) systems. Eg: A 16-storey building with a 4,000 sq. ft rooftop can install only a 40 kWp RTS system, but its south-facing façade can support 150 kWp BIPV panels.
    • Efficient Use of Building Surfaces: BIPV allows power generation from vertical and horizontal surfaces like façades, windows, and balconies, thus using more surface area. Eg: Façade areas of buildings are often 3–4 times larger than rooftop areas, offering greater solar potential.
    • Supports Sustainable Urban Growth: With India’s urban population projected to reach 850 million by 2051, BIPV enables renewable energy adoption in future infrastructure. Eg: Integration of BIPV in new public infrastructure (e.g., metro stations, airports) can reduce carbon footprint.
    • Energy Access for Non-Rooftop Households: Residents in multi-storey apartments without rooftop access can still benefit from solar energy via BIPV on balconies, railings, or windows. Eg: In Germany, 15 lakh households use balcony solar panels, reducing electricity bills by up to 30%.
    • Aesthetic and Space-Neutral Design: BIPVs blend into building designs without occupying extra space or affecting aesthetics, which is ideal for space-constrained urban settings. Eg: The Renewable Energy Museum in Kolkata has a solar-powered dome with over 2,000 integrated panels, combining function with form.

    What challenges are limiting the adoption of BIPVs in India?

    • High Initial Costs: BIPV systems are more expensive than traditional rooftop solar due to integration with building materials and use of advanced technology.
    • Policy and Regulatory Gaps: Lack of clear policies, mandates, and incentives specific to BIPV hinders its integration into mainstream construction practices. Eg: Unlike Europe’s Energy Performance of Buildings Directive, India’s National Building Code does not yet mandate or promote BIPV use.
    • Low Awareness and Technical Capacity: Architects, builders, and homeowners are often unaware of BIPV’s benefits or how to incorporate it effectively in design.
    • Dependence on Imports and Limited Domestic Manufacturing: India relies heavily on imported BIPV components, increasing costs and reducing supply reliability. Eg: Specialised BIPV glass panels or semi-transparent modules are often imported from China or Europe due to lack of local alternatives.
    • Absence of Standardisation and Performance Guidelines: There are no clear standards, benchmarks, or guidelines for BIPV performance, quality, and installation, causing hesitation among developers. Eg: Without defined safety and efficiency norms, urban local bodies may delay approvals or avoid BIPV in building plans.

    What measures can India take to scale up the uptake of BIPVs effectively? (Way forward)

    • Introduce Targeted Policy Incentives and Subsidies: India should extend solar subsidy schemes to specifically support BIPV adoption, especially in space-constrained urban areas. Eg: Under the PM Surya Ghar Muft Bijli Yojana (2024), BIPV was included with subsidies up to ₹78,000 for a 3-kW residential system. Similar support is needed for commercial and industrial sectors.
    • Embed BIPV in Building and Energy Codes: Integrating BIPV requirements into the National Building Code, Energy Conservation Building Code, and Eco Niwas Samhita can make its use more widespread and standardized. Eg: Europe’s Energy Performance of Buildings Directive mandates solar use in new constructions and promotes BIPV with clear regulations—India can adopt a similar model.
    • Promote Domestic Manufacturing and Demonstration Projects: Boosting indigenous production through PLI schemes, along with pilot projects in public infrastructure (e.g., schools, airports), can improve visibility and reduce costs. Eg: The CtrlS Datacenters in Navi Mumbai and Kolkata’s Renewable Energy Museum show how BIPV can be scaled in real-world infrastructure.

    Mains PYQ:

    [UPSC 2020] India has immense potential of solar energy though there are regional variations in its development. Elaborate.

    Linkage: Building-Integrated Photovoltaics (BIPV) is a key solution for boosting solar adoption, especially in densely populated urban areas where traditional rooftop solar (RTS) is constrained by limited shadow-free space. BIPV transforms entire buildings into power generators by integrating solar elements directly into architectural elements, using available surfaces more efficiently and contributing significantly to India’s solar capacity goals.

  • Expert Committee recommends ending mandatory Flue Gas Desulphurisation (FGD) 

    Why in the News?

    A high-powered committee chaired by Principal Scientific Advisor (PSA) Ajay Sood has proposed that India should discontinue the mandatory use of Flue Gas Desulphurisation (FGD) units in most coal-fired Thermal Power Plants (TPPs).

    Why mandatory FGDs are opposed?

    • Low SO₂ Levels: India’s SO₂ levels (10–20 µg/m³) are already below the permissible limit of 80 µg/m³.
    • Low Sulphur Coal: Indian coal naturally has low sulphur content.
    • Minimal Impact: Studies show no major air quality difference between plants with and without FGDs.
    • Limited PM Reduction: FGDs have minimal effect on particulate matter levels.
    • Environmental Trade-Offs:
      • CO₂ Increase: Installing FGDs would add 69 million tonnes of CO₂ emissions (2025–2030).
      • SO₂ Reduction: Emissions would fall by 17 million tonnes, but the climate cost outweighs the benefit.

    About Flue Gas Desulphurisation (FGD):

    • Purpose: FGD is a technology used to remove sulphur dioxide (SO₂) from flue gases produced by burning coal and oil, especially in thermal power plants.
    • Environmental Benefit: It helps prevent acid rain, which harms crops, buildings, soils, and aquatic ecosystems.
    • Chemicals Used: Common absorbents include limestone (CaCO₃), lime (CaO), and ammonia (NH₃).
    • Types of Systems:
      1. Dry Sorbent Injection: Cost-effective, but less efficient.
      2. Wet Limestone-Based: Effective and used in large plants, produces gypsum.
      3. Seawater-Based: Uses alkaline seawater, ideal for coastal areas.

    FGD Mandate in India:

    • Current Status: FGD units are being installed in 537 coal-based thermal power units, but 92% of India’s 600 plants still lack them.
    • Committee Recommendation: An expert panel advised exempting 80% of plants from FGD requirements due to feasibility issues.
    • Implementation Barriers: Limited vendors available; High costs and risk of increased electricity tariffs.

  • How the technology industry is trying to meet its climate goals

    Why in the News?

    A groundbreaking study by Microsoft and WSP Global, published in Nature, shows major progress in making data centres more environmentally friendly.

    What are Data centres? 

    Data centres are specialized facilities used to store, process, and manage data for organizations. They house large numbers of computer servers, network equipment, storage systems, and cooling systems, and form the backbone of the digital infrastructure that powers the internet, cloud computing, and various IT services.

    What are the environmental benefits of using cold plates and immersion cooling in data centres?

    • Lower Greenhouse Gas Emissions: These methods reduce emissions by 15–21% compared to traditional air cooling. Eg: Microsoft’s study showed that using immersion cooling in their data centres significantly reduced carbon emissions during peak operations.
    • Reduced Energy Consumption: They use 15–20% less energy, as liquid coolants transfer heat more efficiently than air. Eg: Alibaba’s deployment of cold plate cooling led to lower power usage effectiveness (PUE), cutting energy bills and environmental impact.
    • Significant Water Conservation: Water usage drops by 31–52%, helping conserve freshwater resources Eg: In water-stressed regions like Arizona, using cold plate cooling helps tech firms operate data centres without heavy reliance on water-based air conditioning systems.

    How does life cycle assessment aid in evaluating cooling technologies?

    • Measures Full Environmental Impact (Cradle to Grave): LCA evaluates emissions, energy use, and water consumption across a product’s entire lifecycle — from manufacturing to disposal. Eg: The Microsoft-WSP study assessed cold plates and immersion cooling from production to end-of-life, revealing their overall environmental benefits.
    • Identifies Trade-offs Between Technologies: LCA highlights sustainability trade-offs, helping compare the true impact of different cooling methods. Eg: It showed that while immersion cooling reduces emissions, the type of coolant used may raise separate ecological concerns.
    • Supports Informed Decision-Making for Climate Goals: LCA provides data-driven insights for industry and policymakers to adopt greener technologies that align with emissions targets. Eg: The ICT sector can use LCA results to choose cooling systems that help cut emissions by 42% by 2030, as per global climate goals.

    Why is renewable energy essential for sustainable data centre cooling?

    • Drastically Reduces Carbon Emissions: Using renewable energy like solar or wind can cut emissions by 85–90%, regardless of the cooling technology used. Eg: A data centre powered by wind energy in Sweden showed near-zero emissions even with traditional air cooling.
    • Enhances the Impact of Green Cooling Technologies: When combined with cold plates or immersion cooling, renewables amplify environmental benefits by further lowering energy and water use. Eg: The Microsoft-WSP study found that with 100% renewables, water savings could increase up to 50%.
    • Ensures True Sustainability Across the System: Cooling innovations alone aren’t enough if the electricity source is polluting; renewables make the entire system eco-friendly. Eg: A server cooled efficiently but powered by coal-based electricity still carries a high carbon footprint.

    In what ways are liquid-cooling methods superior to air cooling?

    • Higher Cooling Efficiency and Performance: Liquid-cooling systems like cold plates and immersion cooling transfer heat more efficiently than air, reducing the risk of overheating and improving hardware performance. Eg: In Microsoft’s data centres, cold plate cooling reduced component temperatures significantly compared to air-cooled setups, boosting system reliability.
    • Lower Energy and Water Consumption: Liquid methods use 15–20% less energy and up to 52% less water, making them more sustainable and cost-effective in the long run. Eg: Alibaba’s immersion-cooled servers showed reduced electricity bills and water usage in high-demand operations.

    To what extent can cooling innovations help meet ICT emission targets by 2030?

    • Significant Reduction in Greenhouse Gas Emissions: Advanced cooling technologies like cold plates and immersion cooling can reduce ICT data centre emissions by 15–21%, directly contributing to the 42% emission cut target set for 2030 (from 2015 levels). Eg: Microsoft’s deployment of cold plate systems showed measurable emissions drops in large-scale data operations.
    • Supports Scalable, Energy-Efficient Data Centre Growth: As demand for cloud services increases, liquid cooling enables high-performance computing without a corresponding rise in energy and carbon footprint, helping the sector scale sustainably. Eg: Alibaba’s use of immersion cooling enabled expansion of AI and cloud infrastructure while keeping energy use in check.

    Way forward: 

    • Promote Policy Incentives for Green Cooling Technologies: Governments should provide tax breaks, capital subsidies, and faster approvals for data centres that adopt liquid-cooling systems and renewable energy integration. Eg: Extending schemes like India’s PLI (Production-Linked Incentive) to green tech in data centres can fast-track low-emission infrastructure adoption.
    • Mandate Life Cycle Assessments and Emission Reporting: Introduce mandatory Life Cycle Assessments (LCA) and carbon disclosure norms for large-scale data centres to encourage transparent, science-based decisions. Eg: Requiring firms to report environmental impact from cooling systems can guide smarter industry shifts aligned with ICT sector’s 2030 emission targets.

    Mains PYQ:

    [UPSC 2022] How will India achieve the target of 50% of its installed capacity from renewable energy by 2030? Justify your answer. How will the shift of subsidies from fossil fuels to renewables help achieve the above objective? Explain.

    Linkage: Switching to renewable energy is a more effective way for the tech industry to run energy-hungry data centers in a cleaner, more sustainable way. This helps them meet climate goals and support national environmental targets.

    • About: A tiger safari is a tourist activity where visitors observe tigers in natural-like habitats, usually around tiger reserves.
    • Legal Status: The Wildlife Protection Act, 1972 does NOT define tiger safaris but restricts construction in protected areas unless approved by the National Board for Wildlife.
    • Policy Origin: The idea was formally introduced in 2012 by the National Tiger Conservation Authority (NTCA) under its tourism guidelines.
    • Rules on Tiger Inclusion (2016): Initially, safaris were allowed only in buffer or fringe zones and could host rescued or conflict tigers, not zoo-bred ones.
    • Amended Rules (2019): The NTCA later allowed even zoo-bred tigers, with Central Zoo Authority (CZA) in charge of animal welfare.
    • Supreme Court Ruling (2024): The court ordered that safaris must be built outside core and buffer zones to protect wild habitats.

    About Jharkhand’s Tiger Safari Project:

    • Location: Planned in the Barwadih Western Range, outside core and buffer zones of Palamau Tiger Reserve (PTR), in line with the Supreme Court’s order.
    • Animal Inclusion: Will house only rescued, injured, or orphaned tigers from various reserves and zoos — not wild tigers from PTR.
    • Tourism and Employment: The project aims to boost tourism and create jobs for around 200 locals as guides and staff.
    • Approval Process: The plan is still in early stages. After state Forest Department approval, a Detailed Project Report (DPR) will go to NTCA and CZA.

  • Culling of Vermins

    Why in the News?

    The Kerala Cabinet is exploring the legal possibility of introducing a bill to permit scientific and regulated culling of wild animals, particularly feral boars.

    What are Vermins?

    • Definition: Vermins are animals considered harmful or nuisance-causing because they damage crops, threaten livestock, or pose risks to human life and property.
    • Examples: Common vermins include rats, mice, common crows, and fruit bats.
    • Legal Effect: When an animal is classified as vermin, it loses legal protection and becomes exempt from conservation safeguards.

    Provisions Related to Vermin in Wildlife Protection Act (WPA), 1972:

    • Schedule V: Lists animals classified as vermin, which can be hunted freely.
    • Section 62: Allows the central government to declare any wild animal (except those in Schedule I and Part II of Schedule II) as vermin for a specified area and time period.
    • Protection Status: Once declared vermin, the animal is treated as a Schedule V species, losing protection.
    • Exclusions: Animals in Schedules I and II (e.g., tigers, elephants) enjoy the highest protection and cannot be declared vermin.
    • Section 11: Chief Wildlife Wardens can allow trapping, capture, or killing of animals like wild boars in cases of public safety or property damage.
    • Wildlife Protection (Amendment) Act, 2022:
      • Reduction of Schedules: From six to four, with Schedule V has been removed.
      • Direct Declaration Power: It allows the Centre to directly declare any species (except those in Schedule I) as vermin, enabling broader culling without the older categorisation system.

    How are Vermins Declared?

    • State Initiation: The state sends a formal request to the Ministry of Environment, Forest and Climate Change (MoEFCC).
    • Declaration: If justified, the Centre issues a notification, declaring the species vermin for a specific region and time frame.
    • Temporary Status: This declaration is not permanent and applies only to the area and time mentioned.
    • Examples:
      • Wild boar in Uttarakhand
      • Nilgai (blue bull) in Bihar
      • Rhesus monkeys in Himachal Pradesh
