  • Why some PLI schemes are in the slow lane?

    Why in the News?

    Six out of the 14 Production-Linked Incentive (PLI) schemes, including textiles, solar modules, IT hardware, automobiles, advanced chemical cells (ACC), and speciality steel, are progressing at a relatively slower pace.

    What are the primary reasons for the slow implementation of PLI schemes?

    • Stringent Eligibility Norms: Many industries have reported that the eligibility criteria for participation in PLI schemes are too stringent, which limits the number of companies that can benefit from the incentives.
    • Initial Setup Challenges: Establishing a domestic manufacturing base from scratch is a monumental task. Industries such as solar modules and advanced chemistry cells (ACC) require substantial time—ranging from one-and-a-half to three years—to set up manufacturing operations, delaying employment generation.
    • Access to Resources: Companies face difficulties in accessing critical resources, including Chinese machinery and skilled technicians, which can hinder their ability to ramp up production quickly.
    • Market Dependency: Some sectors remain heavily reliant on imports and have not yet transitioned to a self-sufficient manufacturing model, impacting their growth under the PLI framework.
    • Slow Disbursement of Funds: The initial years of the scheme saw minimal disbursement of funds, with only a small percentage of the total incentive outlay being paid out in the first two years.

    Which sectors are experiencing the most significant slowdowns, and why?

    • Textiles: This sector is struggling due to high competition and stringent norms that have slowed down participation and growth.
    • Solar Modules: Despite being a strategic sector for renewable energy, delays in establishing manufacturing capabilities have led to slow progress.
      • As of June 2024, India’s solar module manufacturing capacity reached 77.2 GW, but the solar cell capacity was only 7.6 GW, leading to supply shortages that delayed projects.
    • Automobiles: While some companies are making progress, the automobile sector overall is hindered by initial setup challenges and fluctuating market conditions
      • Factors such as rising raw material costs and shifts in consumer preferences towards electric vehicles are creating a complex environment for traditional automakers.
    • Advanced Chemical Cells (ACC): Similar to solar modules, this sector faces long commissioning periods that delay employment outcomes. Because of the lengthy development timelines for manufacturing facilities and the need for substantial investment in technology are contributing to slower growth in this strategic area.
    • IT Hardware: Although recently upgraded with increased funding, it still lags behind in implementation compared to more successful sectors like mobile manufacturing.

    What measures can be taken to enhance the effectiveness of PLI schemes? (Way forward)

    • Revising Eligibility Criteria: Simplifying the eligibility requirements could encourage more companies, especially smaller firms, to participate in the schemes and benefit from incentives.
    • Increasing Support for Supply Chains: Establishing robust supply chains is crucial. The government could provide additional support to smaller suppliers who are essential for scaling up production across sectors.
    • Streamlining Resource Access: Facilitating easier access to necessary machinery and skilled labor can help companies ramp up production more effectively and reduce dependency on imports.
    • Regular Reviews and Adjustments: Continuous monitoring and adjustments based on sector performance can help identify bottlenecks early and allow for timely interventions.
    • Encouraging Ancillary Industries: Promoting the establishment of ancillary industries around larger beneficiaries could create additional jobs and enhance local manufacturing capabilities.

  • [pib] Breakthrough in Quantum Noise Research

    Why in the News?

    Researchers at the Raman Research Institute (RRI) found that quantum noise—usually seen as a problem—can sometimes help connect particles in a special way called entanglement, which is important for future quantum technologies.

    What is Quantum Noise?

    • Overview: Quantum noise refers to random disturbances that affect quantum systems, often causing loss of coherence or decoherence.
    • Traditional View: It is typically seen as harmful, especially for quantum entanglement, which is crucial for quantum computing and communication.
    • Entanglement Concept: It is a phenomenon where particles are so correlated that the state of one instantly affects the state of another, even at a distance.
    • Effect of Decoherence: Noise-induced decoherence breaks this entanglement, thereby reducing the efficiency of quantum technologies.

    Key Findings:

    • Observation: Found that quantum noise can generate or revive entanglement, contrary to its typical reputation as destructive.
    • Focus Area: Studied intraparticle entanglement, which involves internal properties (like spin and path) of a single particle.
    • Contrast with Interparticle Entanglement: Unlike interparticle entanglement (between separate particles), intraparticle entanglement showed resilience under noise.
    • Types of Noise Studied:
      • Amplitude Damping: Energy loss
      • Phase Damping: Loss of phase information
      • Depolarizing Noise: Random changes in quantum state
    • Major Observation: Under amplitude damping, intraparticle entanglement showed delayed decay, revival, and even creation from unentangled states.
    • Interparticle Comparison: In contrast, interparticle entanglement exhibited steady decay with no revival or generation.

    Scientific Implications:

    • New Perspective: Challenges the assumption that quantum noise is purely harmful, showing it can be a resource in certain contexts.
    • Technological Potential: Intraparticle entanglement is more noise-resilient, making it valuable for stable quantum devices.
    • Application Areas: Findings are relevant to quantum communication, QKD (quantum key distribution), quantum computing, and quantum sensing.
    • Predictive Advantage: The new formula allows precise prediction of entanglement behavior, aiding the design of robust systems.
    • Platform Independence: Results are platform-agnostic, applicable to photons, neutrons, trapped ions, etc.

  • Scientists decode Locust Pheromones for Eco-Friendly Control

    Why in the News?

    Researchers in China have discovered a method to curb locust swarming by manipulating their pheromones, paving the way for eco-friendly locust control.

    What are Locust Swarms?

    • Locusts are large grasshoppers capable of forming massive swarms, consuming up to their body weight in food daily, and travelling 150 km/day with favourable winds.
    • They are highly destructive, stripping crops and threatening food security. A single swarm can consume food equivalent to the daily needs of 35,000 people.
    • In India, Locust Control and Research (LC&R) oversees locust management.
    • The Locust Warning Organisation (LWO), established in 1939, monitors and controls locust activity in states like Rajasthan, Gujarat, Punjab, and Haryana.
    • The 2019-2022 desert locust outbreak was one of the worst in decades, devastating India, Pakistan, and East Africa, destroying over 200,000 hectares of crops.
    • Despite existing control measures, locust outbreaks remain difficult to manage due to their rapid breeding capabilities.

    About Locust Pheromones:

    • Locust Behavioural Phases: Locusts exhibit two behavioural phases—solitary (non-swarming) and gregarious (swarming). The shift to gregariousness leads to swarm formation.
    • Key Pheromone – 4-Vinylanisole (4VA):
      • Identified in 2020 by Chinese researchers.
      • Released from locusts’ hind legs after feeding, especially due to the digestion of phenylalanine (a plant compound).
      • Acts as an aggregation pheromone, attracting other locusts and triggering group behaviour.
    • Biochemical Pathway:
      • Enzymes 4VPMT1 (dominant) and 4VPMT2 convert a precursor molecule (4VP) into 4VA.
      • This process is crucial in converting solitary locusts into swarm-forming gregarious ones.

    Recent Breakthrough and Its Implication:

    • Discovery: Researchers at the Chinese Academy of Sciences genetically blocked 4VPMT1, preventing locusts from producing 4VA and stopping swarm formation.
    • Limitations: 4NP is toxic and environmentally persistent, raising concerns for large-scale deployment.
    • Strategy Proposed: RNA interference (RNAi)-based biopesticides targeting 4VPMT genes to prevent 4VA production without toxicity.
    • Wider Implications:
      • Marks the first pollution-free molecular approach to locust control.
      • Can reduce reliance on synthetic pesticides, protect crops, and support sustainable agriculture.
      • Offers a precision pest control model based on insect behavioural biochemistry.

  • In news: Great Trigonometric Survey (GTS)

    Why in the News?

    This newscard highlights the role of Indian assistants in completing the Great Trigonometric Survey (GTS), which began in 1802 to map India’s geography.

    About the Great Trigonometrical Survey (GTS):

    • Launch and Objective: The GTS was a massive scientific and cartographic initiative launched in 1802 by the British to map India with unprecedented precision using trigonometry and geodesy.
    • Initiator: It was conceptualised by William Lambton, a British army officer, and carried out under the East India Company.
    • Purpose: It aimed to measure Earth’s curvature, create accurate maps, and support colonial administration, scientific research, and military planning.
    • Survey Method: It used triangulation, involving a network of interconnected triangles built from a known baseline to calculate distances and angles over large areas.
    • First Baseline: The initial baseline was measured in 1802 at St. Thomas Mount near Madras (Chennai) and extended over 2,600 km up to the Himalayas.
    • Instruments Used: The survey used massive theodolites (weighing up to half a ton) and measuring chains, requiring large teams for operation and transport.
    • Scientific Outcome: It led to the formulation of the Everest Spheroid, a geodetic reference model still used for mapping in South Asia.
    • Duration and Leadership: Although planned to take 5 years, the project lasted nearly 70 years (until 1871) and was led by successors such as George Everest (after whom Mt. Everest was named), Andrew Scott Waugh, and James Walker.

    How did the GTS led to the Mapping of India?

    • First Accurate Maps: It provided scientific maps that corrected earlier errors, enabling modern geodetic frameworks for administration and infrastructure.
    • Survey Range: It mapped from southern India to the Himalayas, supporting large-scale development and scientific measurement.
    • Great Arc Measurement: It measured the Great Arc (Chennai to Dehradun), a significant geodetic arc that helped calculate Earth’s curvature.
    • Himalayan Heights: Using triangulation data, the survey measured 79 Himalayan peaks, including Mount Everest, K2, and Kangchenjunga.
    • Mount Everest Identification: In 1852, Peak XV was identified as the world’s highest mountain, later named Mount Everest in honour of George Everest.
    • Latitude-Longitude System: It produced precise longitude and latitude coordinates, crucial for navigation, military logistics, and administration.
    • Infrastructure Impact: Survey benchmarks supported railways, roads, canals, and earthquake studies, many of which remain relevant today.

    Contribution of Indians to the GTS:

    • Syed Mir Mohsin Husain: A jeweller from Arcot who repaired critical instruments and was later appointed as an instrument maker in the Surveyor General’s office.
    • Radhanath Sikdar: An Indian mathematician who calculated the height of Mount Everest in 1852, confirming it as the tallest peak globally.
    • Indian Field Workers: Thousands of Indian flagmen, khalasis, and labourers undertook challenging tasks like carrying heavy equipment, setting markers, and working in hazardous environments.
    • Logistical Support: Indian artisans and technicians repaired, calibrated, and adapted instruments, making the project feasible under Indian conditions.
    • Role of Pundits: Trained Indian “pundits” conducted secret surveys in Tibet and politically sensitive regions, where British officers were restricted.

  • Assessing India’s Carbon Credit trading scheme targets 

    Why in the News?

    The Indian government recently set greenhouse gas (GHG) emissions intensity targets for key industrial sectors under its Carbon Credit Trading Scheme (CCTS). These targets apply to eight major industries, including steel, cement, aluminium, and textiles, and aim to reduce emissions per unit of production.

    What is CCTS?

    The Carbon Credit Trading Scheme (CCTS) allows entities—such as factories, refineries, or power plants—that emit less than their permitted carbon limits to earn carbon credits. These credits can then be traded with other entities that have exceeded their emission limits.

    What is the importance of assessing carbon targets at the economy-wide level?

    • Reflects true environmental impact: Evaluating targets at the economy-wide level ensures we understand the overall reduction in greenhouse gas emissions, which is the ultimate goal of climate action.
    • Enables flexible compliance: It allows efficient entities to overachieve and trade credits with less efficient ones, reducing total emissions cost-effectively. Eg: In India’s PAT scheme, cement plants exceeding targets sold energy-saving certificates to aluminium units lagging behind.
    • Aligns with national commitments: It supports the evaluation of whether India is on track to meet its Nationally Determined Contributions (NDCs) and net-zero targets, beyond fragmented sectoral views. Eg: India aims to reduce emissions intensity of GDP by 45% by 2030 – a goal only visible through economy-wide analysis.

    What is the PAT Scheme?

    The PAT Scheme sets energy efficiency targets for large, energy-intensive industries. Companies that exceed their targets earn Energy Saving Certificates (ESCerts), which they can trade with other companies that fail to meet their targets.

    How has the PAT scheme proven effective in reducing energy intensity?

    • Encouraged market-based efficiency: The Perform, Achieve and Trade (PAT) scheme allowed industries to meet energy targets using tradable efficiency certificates, creating a cost-effective compliance mechanism.
    • Achieved aggregate reduction: Despite mixed results at the entity or sector level, overall energy intensity in India declined across PAT cycles, proving its system-wide impact. Eg: Between 2012–14, even as chlor-alkali sector’s intensity rose, combined data showed less energy used per unit of output.
    • Enabled flexible transition: PAT helped industries adopt incremental improvements or buy credits instead of making costly in-house upgrades, ensuring participation without economic strain. Eg: Aluminium units improved production processes, while others chose certificate trading to meet targets.

    Why are entity-level targets insufficient to assess emission reduction?

    • Limited Scope of Impact: Targets at the entity level show progress in isolation and may miss the broader picture. For instance, even if some paper or chlor-alkali plants increase their energy use per unit of output, overall national emissions may still fall due to reductions in other sectors.
    • Focus on Transactions, Not Outcomes: These targets often guide financial trades between companies rather than ensuring actual emissions reduction. A steel plant may meet its target not by cutting emissions but by buying efficiency certificates from another unit.
    • Inconsistency Across Sectors: Emission reductions may vary widely across sectors. While cement and aluminium sectors may improve efficiency, others may lag. Solely relying on entity targets could misrepresent the real national decarbonisation progress.

    What limits the comparison of CCTS targets with past and future benchmarks?

    • Mismatch in Scope: The CCTS targets apply only to a part of India’s industrial base, making it difficult to compare them with economy-wide goals like the Nationally Determined Contributions (NDCs). Eg. CCTS covers only 8 industrial sectors, while NDCs span all sectors including agriculture and transport.
    • Changing Baselines and Ambition Levels: Past schemes like PAT Cycle I had relatively modest targets. Comparing them with current CCTS goals may underestimate the urgency for stronger action aligned with net-zero by 2070. Eg. A sector that achieved 1% reduction earlier may now require over 2.5% annual reduction to stay on track.
    • Different Indicators Used: Past targets often focused on energy intensity, while future goals (like NDCs) emphasise emissions intensity per GDP or value added, making direct comparison methodologically inconsistent. Eg. Comparing energy saved per unit of production vs emissions per unit of GDP distorts true climate ambition.

    How do CCTS targets align with India’s NDC and net-zero goals?

    • Partial Alignment with Emission Intensity Reduction: The CCTS targets aim to reduce emissions intensity in key industrial sectors, contributing to India’s NDC goal of reducing emissions intensity of GDP by 45% by 2030 (compared to 2005 levels). However, the annual reduction rateof ~1.68% in CCTS sectors is lower than the required pace for full alignment.
    • Lag Behind Power Sector Decarbonisation: Compared to the power sector, which has low-cost mitigation options and a projected 3.44% annual decline in emissions intensity, the industrial sector’s slower pace (~2.53%) under CCTS may hinder the broader net-zero pathway.
    • Need for Greater Sectoral Ambition: The current CCTS trajectory appears less aggressive than necessary for the 2070 net-zero target. Without scaling upambition across more sectors and tightening targets, CCTS alone cannot ensure full alignment with India’s long-term climate goals.

    Way forward: 

    • Enhance Sectoral Ambition with Dynamic Targeting: Revise CCTS targets periodically based on economy-wide modelling aligned with India’s NDC and net-zero goals, ensuring progressively stringent emission intensity reductions across all major industrial sectors.
    • Integrate Technology and Incentives: Promote adoption of clean technologies through financial incentives, carbon pricing, and capacity-building support to enable industries to decarbonize efficiently without compromising growth.
