  • Coastal Zones Management and Regulations

    How India ‘added’ more than 3,500 km to its coastline

    Explained | Geography | Mains Paper 1: Geographical Features & Their Location

    Why in the News?

    India’s coastline has increased by about 48%, not because of new land but due to better digital mapping and updated measurements. It has grown from 7,516 km to 11,098 km, giving a clearer view of the country’s natural borders.

    What led to the increase in India’s measured coastline length?

    • Use of High-Resolution Mapping Technology: The shift from low-resolution (1:4,500,000) to high-resolution data (1:250,000) allowed finer measurement of the coastline’s bends and curves. Eg: Modern GIS software captured intricate coastal shapes that older manual methods missed.
    • Inclusion of Previously Omitted Offshore Islands: Many small offshore islands that were earlier not visible or excluded due to manual limitations are now included. Eg: Several minor islands around the Andaman & Nicobar and Lakshadweep regions added extra coastline length.
    • Coastline Paradox and Irregularity of Landforms: Coastlines are naturally irregular; measuring them at a finer scale captures more detail, thus increasing total length. Eg: Like using a one-meter ruler instead of a one-kilometre one—more small features are counted, increasing overall length.

    Why is the coastline paradox relevant to India’s coastal mapping?

    • Scale-Dependent Measurement: The coastline paradox shows that a coastline’s length varies based on the scale or resolution used for measurement—the finer the scale, the longer the coastline appears. Eg: Measuring with 1:250,000 scale data gives a much longer length than with 1:4,500,000 scale data.
    • Irregular Nature of Coastlines: Coastlines are highly irregular, full of bends, curves, and inlets, which get missed at lower resolutions but captured at higher ones. Eg: A low-resolution map smooths out land features, while high-resolution GIS tools map every minor curve.
    • No Fixed Length: The paradox proves that coastlines do not have a finite length—they can always be measured in more detail, leading to ever-changing figures. Eg: Even with current high-tech tools, the actual coastline length keeps increasing with better precision in future reassessments.

    How does reassessing the coastline and islands impact governance and security?

    • Accurate Administrative and Developmental Planning: Reassessment provides a clear understanding of territorial boundaries, aiding in efficient governance and infrastructure development. Eg: Updated coastline data helps plan coastal roads, ports, and disaster response systems in states like Gujarat and West Bengal.
    • Strengthening Maritime Security and Surveillance: Precise mapping helps in identifying vulnerable points, enabling better deployment of naval and coast guard resources. Eg: Mapping of remote islands assists in setting up radar stations and surveillance posts in regions like Lakshadweepand Andaman & Nicobar.
    • Strategic Assertion and Environmental Management: Helps in asserting sovereignty over maritime zones and managing coastal ecosystems more effectively. Eg: Reassessment supports India’s claim over its Exclusive Economic Zone (EEZ) and strengthens climate resilienceplanning in coastal areas.

    What challenges exist in accurately counting India’s offshore islands?

    • Ambiguity in Definitions and Tidal Variations: Some landforms may appear as islands during high tide but get connected to the mainland during low tide, causing confusion in classification. Eg: Certain coastal features in Sundarbans and Gulf of Khambhat shift between island and non-island status based on tide levels.
    • Discrepancies Across Agencies and Lack of Standardisation: Different agencies like state governments, Coast Guard, and Surveyor General have reported varying island countsdue to inconsistent definitions and methods. Eg: In 2016, the Surveyor General listed 1,382 islands, while other agencies reported 1,334, leading to a need for data reconciliation.

    Way forward: 

    • Standardised Methodology and Regular Reassessment: Adopt a uniform classification system for islands and coastlines across all agencies, and institutionalise periodic reassessments using high-resolution GIS and satellite data every 10 years.
    • Integrated Coastal Management and Strategic Mapping: Develop a centralised coastal database linking administrative, ecological, and security data to support policy-making, climate resilience, and maritime defence planning.

    Mains PYQ:

    [UPSC 2024] In a crucial domain like the public healthcare system, the Indian State should play a vital role to contain the adverse impact of marketisation of the system. Suggest some measures through which the State can enhance the reach of public health care at the grassroots level.

  • Foreign Policy Watch: India – EU

    Explained: Significance of PM Modi’s Croatia visit, and India’s historic ties with the country

    Explained | International Relations | Mains Paper 2: Bilateral, Regional and Global Groupings and agreements involving India

    Why in the News?

    Prime Minister is visiting Croatia as part of his three-nation tour, which includes Cyprus and Canada. It is his first foreign trip since Operation Sindoor and the first-ever by an Indian PM to Croatia.

    Why is India’s PM’s visit to Croatia strategically important for India-Europe ties?

    • First-Ever Visit Signals Diplomatic Priority: PM of India visit marks the first by an Indian Prime Minister to Croatia, signalling India’s intent to strengthen ties with smaller but strategically located EU nations. Eg: This visit follows recent high-level engagements with the EU, including EAM S. Jaishankar’s tour of key European nations and the EU chief’s visit to India.
    • Gateway to Broader European Engagement: Croatia’s location on the Adriatic Sea and participation in EU and NATO makes it a vital link for India to access Central, Eastern, and Southern Europe. Eg: Ports like Rijeka and Split could serve as future nodes for the India-Middle East-Europe Economic Corridor (IMEC).
    • Strategic Counter to China’s Growing Presence: The visit is a part of India’s effort to counterbalance Chinese influence in the region through the Belt and Road Initiative (BRI) by building stronger ties with countries like Croatia. Eg: Croatia is part of the Three Seas Initiative (3SI), where India can build alternative trade and energy partnerships.

    What is the significance of Croatia’s location in India’s trade and connectivity plans?

    • Strategic Adriatic Sea Access to Europe: Croatia is located on the Adriatic Sea, offering India a western maritime gateway to Europe and easy access to landlocked Central and Eastern European nations. Eg: Ports like Rijeka, Split, and Ploče can facilitate India-Europe cargo movement, reducing dependence on northern European routes.
    • Link to Trans-European Transport Corridors: Croatia sits at the intersection of the Trans-European Transport Network (TEN-T), enabling smoother logistics and intermodal trade connectivity across the EU. Eg: Goods arriving at Croatian ports can be distributed via rail or road to Germany, Austria, Hungary, and beyond.
    • Potential Hub in the India-Middle East-Europe Economic Corridor (IMEC): Croatia could be a key extension point in IMEC, connecting India to Europe through Middle Eastern and Mediterranean routes. Eg: A route through Adriatic ports would offer faster, diversified supply chain options to bypass chokepoints like the Suez Canal.

    How have India-Croatia relations evolved since Yugoslavia’s breakup?

    • Early Recognition and Diplomatic Ties: India was among the first non-European countries to recognise Croatia’s independence in 1992 and quickly established formal diplomatic relations. Eg: The Indian mission in Zagreb opened in 1996, and ties were upgraded to the ambassadorial level by 1998.
    • Continuity of Warm Relations from Yugoslav Era: Friendly ties from the Non-Aligned Movement (NAM) days continued, especially since Marshal Tito (of mixed Croatian and Slovene heritage) had a strong personal rapport with Indian leadership. Eg: Croatia once accounted for two-thirds of India-Yugoslavia trade, laying a historical economic foundation.
    • Stable Relations Amid Croatia’s Western Integration: Despite Croatia’s focus on EU and NATO membership, India maintained cordial ties and engaged through trade, cultural diplomacy, and multilateral platforms. Eg: Croatia joined NATO in 2009 and the EU in 2013, yet bilateral trade and cultural exchanges with India have steadily grown.

    What are the key economic and cultural links between India and Croatia?

    • Growing Bilateral Trade: Economic ties have steadily improved, with bilateral trade increasing from $199.45 million in 2017 to $337.68 million in 2023. Eg: India exports medicines, machinery, chemicals, and apparel, while Croatia exports chemicals, precision instruments, and timber products to India.
    • Deep Cultural and Civilisational Connect: Cultural exchanges trace back centuries, with scholars and missionaries engaging with Indian traditions and languages. Eg: Croatian scholar Ivan Filip Vezdin printed the first Sanskrit grammar in Latin in 1790 after learning from Kerala Brahmins—a reprint was gifted to PM Modi.
    • Academic and Heritage Bonds: Indian culture continues to attract interest in Croatia, particularly in universities and historical architecture. Eg: Croatian involvement in the construction of the Church of Sao Braz in Goa in the 1560s and Indian studies programmes in Croatian academic institutions reflect enduring links.

    Why should India deepen engagement with Central and Eastern Europe amid China’s BRI?

    • Strategic Counter to China’s Expanding Influence: Central and Eastern European (CEE) countries are key participants in China’s Belt and Road Initiative (BRI), increasing Beijing’s geopolitical footprint in the region. Eg: Strengthening ties with countries like Croatia, Poland, and Hungary allows India to offer an alternative partnership model based on mutual respect and balanced trade.
    • Support for India’s Global Aspirations: Many CEE countries support India’s bid for permanent membership in the United Nations Security Council (UNSC)and other multilateral forums. Eg: Engaging with pro-India nations in the EU helps India shape global norms and strengthen its diplomatic leverage.
    • Geostrategic and Economic Gateway to Europe: CEE countries lie at the crossroads of Europe and Asia, making them vital for India’s trade connectivity, energy cooperation, and access to European markets. Eg: Croatia’s role in the Three Seas Initiative (3SI) and its ports linked to Trans-European corridors can serve as hubs for the India-Middle East-Europe Economic Corridor (IMEC).

    Way forward: 

    • Institutionalise Strategic and Economic Dialogue: India should establish regular high-level forums and joint working groups with Croatia and other CEE countries to deepen cooperation in trade, infrastructure, and digital technology.
    • Enhance Cultural and Academic Exchange: Boosting people-to-people ties through scholarships, cultural festivals, and collaborative research will strengthen India’s soft power and foster long-term partnerships across the region.

    Mains PYQ:

    [UPSC 2024] The West is fostering India as an alternative to reduce dependence on China’s supply chain and as a strategic ally to counter China’s political and economic dominance.’ Explain this statement with examples.

    Linkage: Prime Minister Modi’s visit to Croatia, an EU member, is highlighted as part of a broader strategy to strengthen India-EU ties. The article explicitly states that this growing importance of India-EU relations comes in the context of the EU “trying to de-risk from China”.

    India’s First Epigraphical reference to Halley’s Comet found in Vijayanagar Period

    Prelims Only | History | Mains Paper 1: Arts & Culture

    Why in the News?

    The first Indian inscriptional reference to Halley’s Comet has been discovered on a copper plate dated 1456 CE, from the Vijayanagar Period.

    What does the inscription say?

    • The inscription was found on a copper plate dated June 28, 1456 CE, during the Vijayanagar Empire, preserved at the Sri Mallikarjunaswamy temple in Srisailam, Andhra Pradesh.
    • Written in Sanskrit using the Nagari script, it describes the sighting of a comet (dhūmaketu) and a meteor shower, which coincide with the documented appearance of Halley’s Comet that year.
    • The inscription records a village grant made by King Mallikarjuna of Vijayanagar to a Vedic scholar named Limgaṇarya from Kaḍiyalapura (likely present-day Kaḍiyapulanka, Kadapa district).
    • The grant’s purpose is explicitly mentioned: “to mitigate the great calamity believed to arise due to the appearance of a comet and meteor shower”—a reference to traditional beliefs of such celestial events being inauspicious.
    • The Sanskrit phrase “Prakāśyāya mahōtpāta śāntyartham dattavān vibhuḥ” translates to “this grant was made in order to pacify the calamities that may arise due to the illuminating comets and meteor shower upon the king and his kingdom.”
    • Though dhūmaketus (comets) are referenced in ancient Indian astronomical texts, this is the earliest inscriptional record linking a comet to a specific historical date and royal response.

    IIT-D demonstrates Quantum Communication over 1 Km

    Prelims Only | Science Tech | Mains Paper 3: Achievements Of Indians In S&T

    Why in the News?

    The Defence Ministry announced a breakthrough as IIT-Delhi and DRDO scientists successfully demonstrated quantum communication over 1 km in free space.

    What is Quantum Communication?

    • It is a new way of sending messages so safely that no one can secretly listen in.
    • It uses the laws of quantum physics, especially something called quantum entanglement, to make sure that if someone tries to spy on your message, you’ll know immediately.
    • In quantum entanglement, two tiny particles (like photons of light) are connected in a mysterious way—whatever happens to one instantly affects the other, even if they’re far apart.
    • Because of this, if someone tries to distort one particle, it changes, and the system knows the message isn’t safe anymore.
    • This makes quantum communication perfect for defence, banking, and sensitive messages that must stay secret.

    Quantum Key Distribution (QKD) – Explained Simply:

    • Imagine you want to lock a box and send it to your friend, but you also want them to have the key—without anyone else being able to copy it.
    • QKD is a special way to share that key safely, using quantum particles instead of metal keys.
    • Two people use entangled particles to create the same secret key, without anyone else knowing it.
    • If someone tries to intercept the key while it’s being shared, the particles will show signs of disturbance, and the system will know to discard it and try again.
    • Once both people have the same key, they can use it to lock and unlock messages using regular encryption tools.
    • QKD doesn’t send the actual message—it just safely shares the key that keeps messages secret.

    What did the IIT-Delhi team achieve?

    • A team led by IIT-Delhi, in collaboration with DRDO, successfully demonstrated entanglement-based quantum communication over 1 km in free space.
    • This was done within the IIT-Delhi campus and marks a key advancement from previous experiments using only optical fibre.
    • The demonstration achieved a secure key rate of 240 bits per second and maintained a quantum bit error rate (QBER) of under 7%, which is considered acceptable for real-world QKD.
    • This capability is a step toward achieving satellite-to-ground quantum communication, enabling encrypted keys to be distributed across vast regions without physical links.

    India’s Quantum Communication Journey So Far:

    • In 2022, Prof. Kanseri’s team first demonstrated quantum communication between Vindhyachal and Prayagraj.
    • In 2023, they expanded this capability to 380 km using standard telecom fibre, achieving a low QBER of 1.48%.
    • By 2024, the team established a QKD link spanning over 100 km of optical fibre, further pushing the reliability and reach of India’s quantum infrastructure.
    • These achievements are part of India’s larger effort under the National Quantum Mission (2023–2031), which has a budget of ₹6,000 crore to support R&D and deployment in quantum computing, sensing, and communication.
    • India now joins an elite group of nations—alongside China and the US—actively building toward a quantum-secure internet, with potential applications in defence, finance, telecom, and cybersecurity.

     

    [UPSC 2025] Consider the following statements:

    I. It is expected that Majorana 1 chip will enable quantum computing. II. Majorana 1 chip has been introduced by Amazon Web Services (AWS). III. Deep learning is a subset of machine learning.

    [20th June 2025] The Hindu Op-ed: Why India should address its propulsion gap

    op-ed snap | Science Tech | Mains Paper 3: Indigenization Of Technology

    PYQ Relevance:

    [UPSC 2020] What is the significance of Indo-US defence deals over Indo-Russian defence deals? Discuss with reference to stability in the Indo-Pacific region.

    Linkage: The question regarding Indo-US and Indo-Russian defense deals is relevant because India’s propulsion gap directly influences its choices and reliance on these foreign defense partners for critical military hardware like engines. Addressing the propulsion gap would reduce this dependency, enabling India to better assert its strategic autonomy and contribute to regional stability (such as in the Indo-Pacific) without being constrained by external supply chain pressures or technology transfer limitations from other nations.

     

    Mentor’s Comment:  India’s Advanced Medium Combat Aircraft (AMCA) project is moving ahead quickly and is seen as a big step forward for the country’s aerospace sector. However, the excitement is being held back by a long-standing reliance on foreign engines. This same problem had earlier affected the HF-24 Marut and is now also troubling the LCA and AMCA fighter jet programs. Even after years of work and investment — including the unsuccessful Kaveri engine project and delays in getting engines from GE — India still depends heavily on other countries for engine technology. This not only affects military preparedness but also raises serious concerns about India’s ability to act independently in defence matters.

    Today’s editorial analyses the development of Indian fighter aircraft engines. This content would help in GS Paper II (International Relations) and GS Paper III (Science & Technology) in the mains Paper.

    _

    Let’s learn!

    Why in the News?

    Recently, there is growing excitement around India’s AMCA stealth fighter, seen as a major aerospace milestone. However, concerns remain due to a long-standing reliance on imported engines since the HF-24 Marut.

    Why has India failed to develop its own jet engine? 

    • Technological Challenges in Engine Design: Jet engines require high thrust-to-weight ratios, thermal stability, and advanced metallurgy, which India has struggled to achieve. Eg: The Kaveri GTX-35VS engine, under development since 1989 by DRDO-GTRE, failed to meet performance benchmarks in thrust and thermal management even after 3,000 hours of testing.
    • Lack of Core Materials and Manufacturing Capability: India lacks access to critical technologies like single-crystal turbine blades, thermal barrier coatings, and advanced cooling systems, essential for high-performance engines. Eg: Negotiations with GE for F414 engine hit a roadblock because GE refused full transfer of these core technologies despite India’s demand.
    • Fragmented and Short-Term Funding: Defence R&D funding in India is project-specific and often lacks a long-term strategic vision, affecting continuity and innovation in complex projects. Eg: Despite spending over ₹2,032 crore on the Kaveri project over 35 years, no operational engine was produced due to inconsistent support and shifting goals.
    • Over-Reliance on Foreign Engines: Dependence on foreign suppliers has created a complacency in indigenous R&D, slowing domestic capability-building. Eg: India continues to rely on GE F404 and F414 engines for its LCA Tejas variants, instead of pursuing an urgent push for domestic alternatives.
    • Institutional Inertia and Missed International Collaborations: Bureaucratic rigidity and institutional pride have caused India to reject key collaborative opportunities for engine co-development. Eg: A proposed joint project with Safran (France) for developing an engine for AMCA and Tejas MkII was reportedly declined by DRDO.

    What is HF-24 Marut?

    The HF-24 Marut (meaning “Spirit of the Tempest”) was India’s first indigenously designed and built fighter jet, developed in the 1950s and 1960s by Hindustan Aeronautics Limited (HAL).

    What caused the HF-24 Marut’s underperformance?

    • Underpowered Engine: The Marut was equipped with British Bristol Siddeley Orpheus 703 turbojets, which lacked the thrust needed for supersonic performance. Eg: Designer Kurt Tank had envisioned a more powerful engine, but it never materialised, severely restricting the aircraft’s speed and payload capabilities.
    • Failure to Acquire Suitable Alternatives: Despite multiple attempts, India could not procure or co-develop a more suitable engine to enhance the Marut’s performance. Eg: Efforts to source a better engine from Egypt and Germany failed, leaving the Marut stuck with the underpowered Orpheus units.
    • Operational Limitations in Combat: The aircraft performed well in ground-attack roles, such as in the 1971 war, but its overall combat effectivenesswas limited by its propulsion shortfall. Eg: Indian Air Force veterans cited that the engine limitation was the Marut’s Achilles’ heel, preventing it from evolving into a full-spectrum fighter.

    How does engine import dependency impact India’s defence?

    • Delays in Defence Production and Induction: Dependency on foreign engines leads to project delays when there are supply chain issues or export restrictions. Eg: Delivery of 99 General Electric F404 engines for the LCA Mk1A was delayed by 13 months, pushing back aircraft induction timelines.
    • Limited Operational and Strategic Autonomy: India becomes vulnerable to geopolitical pressures and foreign policy decisions of engine-supplying nations. Eg: U.S. reluctance to share core technologies like single-crystal turbine blades restricts India’s ability to upgrade or export its fighter aircraft.
    • Constraints on Defence Exports: Exporting platforms equipped with foreign engines requires third-party approvals, limiting India’s potential in global defence markets. Eg: India’s ability to export Tejas is restricted by U.S. controls on the GE F404 engine, limiting defence diplomacy options.

    What are the steps taken by the Indian Government? 

    • Strategic Collaborations for Technology Transfer: India has initiated joint ventures and international collaborations to acquire advanced propulsion technology. Eg: During PM Modi’s 2023 U.S. visit, HAL signed a deal with General Electric to co-produce GE F414 enginesin India for the LCA Mk2 and AMCA programs.
    • Revival of Indigenous Engine Projects: The government has revived and restructured efforts to develop indigenous jet engines under DRDO’s GTRE. Eg: The Kaveri engine project was decoupled from the LCA program and is being explored for use in UAVs and future aircraft with potential foreign assistance.
    • Promotion of Atmanirbhar Bharat in Defence: The Defence Ministry has prioritized self-reliance in critical technologies, including aero-engines, under the Atmanirbhar Bharat initiative. Eg: Several defence PSUs and private players have been incentivized to develop components and sub-systemsfor aerospace platforms under Make in India schemes.

    What must India do to achieve propulsion self-reliance? (Way forward)

    • Establish Strategic Global Partnerships for Technology Transfer: India must engage in joint ventures with trusted international engine manufacturers to acquire critical technologies like single-crystal turbine blades and thermal barrier coatings. Eg: The proposed GE-HAL deal to manufacture the F414 engines in India should ensure full transfer of know-how to avoid long-term dependency.
    • Develop an Integrated Indigenous R&D Ecosystem: India needs to create a cohesive framework connecting DRDO, GTRE, academia, and private industry to focus on advanced propulsion R&D with long-term investment. Eg: Encouraging private sector participation in defence through the Innovations for Defence Excellence (iDEX)platform can accelerate jet engine innovation.

    The unregulated drink: rethinking alcohol control in India

    Explained | Indian Society | Mains Paper 1: Salient features of Indian Society

    Why in the News?

    India’s rising alcohol use is not just a health issue — it is a major national problem affecting many areas. Even though experts say no amount of alcohol is safe, about one in four Indian men drink. Drinking heavily and often is now becoming more common across the country.

    What are the key risks of alcohol consumption in India?

    • Health Risks and Non-Communicable Diseases (NCDs): Alcohol significantly increases the risk of cancer, liver disease, cardiovascular issues, and mental illnesses. Eg: Chronic alcohol use is a leading cause of liver cirrhosis and is linked to mouth and throat cancers in India.
    • Injuries and Accidents: Alcohol impairs judgement and coordination, leading to road accidents, falls, and workplace injuries. Eg: A large number of road traffic fatalities in India are associated with drunk driving, particularly among youth.
    • Mental Health and Suicide: Alcohol contributes to depression, anxiety, and is a major risk factor for suicide. Eg: The National Suicide Prevention Strategy (2022) identified alcohol use as a key driver of suicides in India.
    • Violence and Crime: Alcohol consumption is linked with domestic violence, sexual assault, and violent crimes. Eg: NFHS-5 data shows higher incidence of domestic violence in households where alcohol is consumed regularly.
    • Economic and Social Burden: Alcohol use contributes to ₹6.24 trillion in societal costs (2021), including healthcare, lost productivity, and law enforcement. Eg: The burden of alcohol-related diseases adds pressure to India’s public health system, particularly in rural areas.

    Why is a national alcohol policy necessary?

    • Fragmented and Inconsistent State Regulations: Alcohol laws, legal drinking age, pricing, and prohibition vary widely across States, causing regulatory confusion and uneven implementation. Eg: Bihar enforces prohibition, while States like Kerala promote toddy as a “natural beverage” under its Akbari Policy.
    • Public Health Emergency: Rising alcohol consumption is linked to cancer, mental illness, suicides, and injuries, posing a major national health burden. Eg: In 2021, alcohol-related harm caused 2.6 million DALYs and cost India ₹6.24 trillion in societal losses.
    • Lack of Centralised Coordination and Accountability: Regulatory responsibility is scattered across multiple ministries with no unified approach, weakening policy impact. Eg: Demand reduction is handled by the Ministry of Social Justice, while supply and harm reduction are spread across Health, Finance, and Home Affairs ministries.

    Who regulates alcohol demand and supply in India?

    • State governments: Regulate production, distribution, pricing, sale, and consumption.
    • Ministry of Social Justice: Leads demand reduction (e.g., Nasha Mukta Bharat Abhiyan).
    • Ministries of Home Affairs, Finance, and Health: Handle supply and harm reduction.
    • No single authority: Regulatory efforts are scattered and lack coordination.

    How do marketing and digital platforms influence alcohol use?

    • Surrogate Advertising and Brand Promotion: Despite legal restrictions, alcohol brands use surrogate advertising, brand sponsorships, and strategic product placements to maintain visibility. Eg: Alcohol brands often sponsor music festivals and sports events, indirectly promoting their products to younger audiences.
    • Social Media and Algorithmic Amplification: Social media algorithms boost alcohol-related content (ARC), while “alcohol influencers” glamorize drinking and normalize it among youth. Eg: Platforms like Instagram and YouTube promote posts showing alcohol as part of a luxury lifestyle, increasing its social appeal.
    • Attractive Packaging and Retail Tactics: Use of sleek bottles, premium branding, and Happy Hour deals enhance the aspirational value of alcohol and make it more appealing. Eg: Pre-mixed cocktails and flavoured spirits are marketed to attract young and first-time users.

    Way forward: 

    • Formulate a Unified National Alcohol Control Policy: Develop a comprehensive, evidence-based policy that aligns efforts across States and Central ministries, focusing on public health, harm reduction, and regulation of digital content.
    • Invest in Public Awareness and Education: Launch large-scale awareness campaigns highlighting the health risks of alcohol, similar to tobacco control programs, to shift social norms and perceptions. Eg: Educating youth on links between alcohol and mental illness, cancer, and poverty can reduce its aspirational appeal.

    Mains PYQ:

    [UPSC 2024] In a crucial domain like the public healthcare system, the Indian State should play a vital role to contain the adverse impact of marketisation of the system. Suggest some measures through which the State can enhance the reach of public health care at the grassroots level.

    All about the revised Green India Mission to increase forest cover, address climate change

    ExplainedSchemes | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia

    Why in the News?

    The revised plan for the Green India Mission (GIM), released by the Centre on June 17, is an important step forward in India’s fight against climate change.

    What are the achievements of the Green India Mission since its launch in 2014?

    • Large-scale Afforestation Activities: GIM facilitated tree plantation and afforestation across 11.22 million hectares between 2015–16 and 2020–21. Eg: Afforestation under state schemes in Andhra Pradesh and Telangana helped increase green cover.
    • Support to Vulnerable States: Funds were allocated based on ecological vulnerability and restoration potential. Eg: ₹624.71 crore released to 18 states between 2019–24, with ₹575.55 crore utilised.
    • Carbon Sequestration Contribution: Contributed to creating an additional carbon sink of 2.29 billion tonnes of CO₂ equivalent between 2005–2021. Eg: Forest restoration in Jharkhand and Chhattisgarh aided national climate goals.
    • Integration with Climate Goals: GIM aligned with India’s international commitment to restore 26 million hectares of degraded land by 2030. Eg: Activities under GIM complement India’s UNFCCC goals on land restoration and carbon capture.
    • Livelihood Enhancement through Forest-Based Interventions: Helped improve livelihoods of forest-dependent communities via sustainable forestry practices. Eg: Community plantation models in Odisha created jobs and promoted conservation.

    What are the key elements of the revised Green India Mission roadmap?

    • Landscape-level restoration: Focus on saturation-based, area-specific restoration in vulnerable landscapes like the Aravallis, Western Ghats, Himalayas, and mangroves.
    • Integration with flagship projects: Syncing with initiatives like the Aravalli Green Wall project (cost: Rs 16,053 crore, coverage: 6.45 mha across 29 districts and 4 states).
    • Aravalli protection: Targeting 8 lakh hectares for forest, water system and grassland rejuvenation to curb sandstorm intrusions and pollution in NCR and Punjab.
    • Western Ghats focus: Addressing illegal mining and deforestation through afforestation and abandoned mine rehabilitation.

    Why was the Green India Mission’s roadmap revised?

    • To Address On-Ground Climate Impacts: The revision was made to respond to changing climate conditions and the increasing urgency of land degradation and desertification. Eg: Inclusion of the Aravalli Green Wall Project to counter desert expansion from the Thar region.
    • To Incorporate Feedback from States and Scientific Bodies: The revised plan reflects inputs from implementing states and scientific institutions, ensuring region-specific solutions. Eg: Feedback led to the addition of eco-restoration of abandoned mining areas in the Western Ghats.
    • To Focus on Region-Specific Restoration Practices: The update prioritises landscape-specific and ecologically appropriate restoration in vulnerable ecosystems. Eg: Special emphasis on Himalayas, mangroves, and degraded zones for carbon sequestration and biodiversity conservation.

    What key regions will it now focus on?

    Who is implementing the Green Wall project?

    • Central Government Leadership: The Centre (Government of India) is spearheading the initiative, allocating funding and coordinating implementation across states. Eg: The project’s ₹16,053 crore budget and planning is directed by central agencies in collaboration with local authorities.
    • Collaboration with States and Scientific Institutions: Implementation involves three states (Haryana, Rajasthan, Gujarat), one UT (Delhi)  and guidance from the Wildlife Institute of India (WII), using ecological data to target 12 degradation gaps in the Aravalli range. Eg: WII studies identified dust-prone regions; restoration covers 8 lakh hectares across 29 districts in these states.

    How will GIM address land degradation and carbon sequestration?

    • Restoration of Degraded and Open Forests: GIM focuses on restoring impaired open forests, which is a cost-effective and high-impact method for carbon dioxide (CO₂) sequestration. Eg: As per the Forest Survey of India (FSI), restoring 15 million hectares can sequester 1.89 billion tonnes of CO₂.
    • Region-Specific Ecological Interventions: The revised roadmap includes landscape-specific afforestation and eco-restoration in vulnerable areas like the Aravallis, Western Ghats, Himalayas, and mangroves. Eg: Under the Aravalli Green Wall Project, 8 lakh hectares will be restored to combat desertification and reduce dust pollution.
    • Expansion of Natural Carbon Sinks: GIM aligns with India’s climate commitment to create an additional carbon sink of 2.5 to 3 billion tonnes of CO₂ by 2030. Eg: By integrating schemes and intensifying plantation efforts, GIM aims to expand forest and tree cover up to 24.7 million hectares, capturing 3.39 billion tonnes of CO₂.

    Way forward: 

    • Integrated Landscape-Based Planning: Adopt a holistic, ecosystem-specific approach by aligning GIM with other environmental programs (e.g., CAMPA, MGNREGS) for coordinated restoration and afforestation efforts.
    • Enhanced Monitoring and Community Participation: Use technology (GIS, remote sensing) for real-time progress tracking, while empowering local communities and forest-dependent groups for sustainable upkeep and livelihood generation.

    Mains PYQ:

    [UPSC 2020] Examine the status of forest resources of India and its resultant impact on climate change.

    Linkage: This question directly relates to the core objectives and context of the Green India Mission (GIM). The GIM, launched in 2014, is a crucial component of India’s efforts to combat climate change by increasing forest and tree cover and restoring degraded ecosystems. The revised roadmap for GIM emphasizes not only increasing and restoring forest and green cover but also tackling land degradation and desertification, which are significant environmental issues in India.
