India’s Poverty Decline: Key Insights from 2011 to 2023
Current (GK) (Current Affairs) Poverty and employment

India has made significant progress in reducing poverty over the past decade. According to a World Bank report, extreme poverty decreased from 16.2% in 2011–12 to 2.3% in 2022–23, lifting approximately 171 million people above the poverty line. 

Key Highlights:

  • Rural and Urban Poverty Reduction: Rural poverty declined from 18.4% to 2.8%, while urban poverty decreased from 10.7% to 1.1%, narrowing the rural-urban poverty gap from 7.7 to 1.7 percentage points. 
  • Transition to Lower-Middle-Income Status: Using the $3.65 per day poverty line, poverty rates dropped from 61.8% to 28.1%, lifting 378 million people out of poverty. Rural poverty decreased from 69% to 32.5%, and urban poverty from 43.5% to 17.2%. 
  • Impact of Major States: In 2011–12, the five most populous states—Uttar Pradesh, Maharashtra, Bihar, West Bengal, and Madhya Pradesh—accounted for 65% of India’s extreme poor. By 2022–23, these states contributed to two-thirds of the overall decline in extreme poverty but still represented 54% of the extremely poor population. 
  • Multidimensional Poverty Index (MPI): The MPI, reflecting non-monetary poverty, decreased from 53.8% in 2005–06 to 16.4% by 2019–21, and further to 15.5% in 2022–23, indicating substantial progress in addressing various poverty dimensions beyond income. 
  • Income Inequality Trends: While the consumption-based Gini index improved from 28.8 in 2011–12 to 25.5 in 2022–23, the World Inequality Database reported rising income inequality, with the Gini index for income increasing from 52 in 2004 to 62 in 2023. This suggests that wage gaps remain, with the top 10% earning 13 times more than the bottom 10% in 2023–24. 
  • Employment Growth: Employment growth has outpaced the working-age population since 2021–22. Urban unemployment fell to 6.6% in the first quarter of FY24/25, the lowest since 2017–18. Notably, there has been a shift of male workers from rural to urban areas, while female employment in agriculture has increased. 

These statistics highlight India's substantial progress in poverty reduction between 2011 and 2023, while also underscoring ongoing challenges related to income inequality and employment.

Fourth Global Bleaching Event
Geography and Environment(BPSC) (Current Affairs) Concept of Ecology

Context

  • The US National Oceanic and Atmospheric Administration in partnership with the International Coral Reef Initiative, confirmed that the world is witnessing its fourth global bleaching event.

About

  • The bleaching-level heat stress has impacted 83.7% of the planet’s coral reef area and mass coral bleaching has been recorded in at least 83 countries and territories. 
    • The ongoing global coral bleaching event is the biggest to date. 
  • Previous Bleaching: 
    • The 1st and 2nd global coral bleaching events occurred in 1998 and 2010, respectively. 
    • The 3rd global coral bleaching event, which occurred from 2014-2017, when 68.2% of the world’s reef area experienced bleaching-level heat stress. 
  • Future Projections: Climate models predict that by 2040-2050, nearly every coral reef worldwide will face annual bleaching events.
  • Great Barrier Reef Status: Currently undergoing a sixth mass bleaching event.
    • Second consecutive bleaching episode after 2016-17.
    • Caused by prolonged marine heatwaves, especially in Far Northern and Northern regions.
  • Bleaching History in Australia: Mass coral bleaching events recorded in 1998, 2002, 2016, 2017, 2020, 2022, and 2024.

What are Corals?

  • Corals are invertebrates that belong to a large group of animals called Cnidaria.
    • Corals are formed by multiple small, soft organisms known as polyps. 
    • They secrete a rocky chalk-like (calcium carbonate) exoskeleton around themselves for protection. 
    • Coral reefs are therefore created by millions of tiny polyps forming large carbonate structures.
  • Appearance: Corals range in colour from red to purple and even blue, but are most commonly shades of brown and green.
    • Coral are bright and colorful because of microscopic algae called zooxanthellae.
  • There are three types of coral reefs – fringing reefs, barrier reefs and atolls.
    • Fringing reefs form along shorelines, barrier reefs form in open water and atolls are circular reefs that have formed around sunken volcanoes.

Coral Bleaching

  • Coral bleaching occurs when corals expel the colourful algae living in their tissues. 
  • Without these helpful algae, the corals become pale and are vulnerable to starvation and disease. 
  • A bleached coral is not dead, but ocean temperatures need to cool off for any hope of recovery.
  • At least 14% of the world’s remaining corals were estimated to have died in the previous two global bleaching events.

What triggers Coral Bleaching?

  • The leading cause of coral bleaching is climate change. 
    • A warming planet means a warming ocean, and a change in water temperature—as little as 2 degrees Fahrenheit—can cause coral to drive out algae. 
  • Coral also bleaches for other reasons, like extremely low tides, pollution, or too much sunlight.

Concerns

  • Coral bleaching matters because once these corals die, reefs rarely come back. 
  • With few corals surviving, they struggle to reproduce, and entire reef ecosystems, on which people and wildlife depend, deteriorate.
  • This would have dire implications for ocean health, subsistence fisheries and tourism. 

Impact of Coral Bleaching

  • Wildlife: Thousands of marine animals depend on coral reefs for survival.
    • Coral reefs provide shelter, spawning grounds, and protection from predators. 
    • They also support organisms at the base of ocean food chains. 
    • As reef ecosystems collapse, already at-risk species may face extinction.   
  • Humans: Coral reefs are natural barriers that absorb the force of waves and storm surges, keeping coastal communities safe. 
    • Every year, reefs provide about $2.7 trillion in goods and services, according to a 2020 estimate by the Global Coral Reef Monitoring Network.
    • Bleached coral also compounds the overfishing crisis by removing links in the food web and depriving some fish of a place to spawn and develop.
    • Reef tourism brings in billions of dollars each year and supports thousands of jobs. 

Can corals recover from bleaching?

  • Corals can recover if conditions improve, but recovery can take years or even a decade, depending on the extent of the damage.
  • Corals can recover only if temperatures drop and conditions return to normal. 
  • When this happens, the algae returns and the corals gradually regain their health.

Can corals recover from bleaching

Way Ahead

  • Strengthening Marine Protected Areas (MPAs).
  • Implementing coral restoration techniques, such as coral gardening and breeding resilient coral species, to enhance recovery after bleaching events.
  • Advocating for global efforts to reduce greenhouse gas emissions to limit temperature increases and ocean acidification.
  • Increasing investment in research to better understand coral resilience, bleaching triggers, and recovery processes, alongside developing advanced monitoring technologies.

Stubble Burning - IIM Research
Geography and Environment(BPSC) (Current Affairs) Pollution

A 2025 study by IIM Amritsar reveals that stubble burning in Punjab is not merely a technological or behavioral issue but is deeply rooted in structural market distortions and state-led policy incentives—particularly the Minimum Support Price (MSP) system. The findings underscore how well-intentioned interventions can inadvertently reinforce unsustainable agricultural practices.


Why Does Stubble Burning Persist in India?

  • Policy-Induced Mono-Cropping:
    The MSP regime predominantly incentivizes wheat and paddy cultivation, especially in Punjab, Haryana, and Uttar Pradesh. This discourages crop diversification, leading to an excess of paddy stubble, which farmers often burn to clear fields quickly for the next sowing cycle.

  • Market Distortions and Farmer Exploitation:
    India's agricultural marketing remains dominated by middlemen (arhtias), who control pricing, credit, and procurement. A 2024 RBI survey revealed that farmers received only 40–67% of consumer prices for major rabi crops. Stagnant MSP rates, rising cultivation costs, and restricted market access push farmers toward cost-cutting measures like stubble burning.

  • Lack of Affordable Alternatives:
    Despite penal regulations, state support for sustainable stubble management solutions remains inadequate. The absence of accessible, low-cost technologies compels farmers to burn residue for expediency.

  • Climate Stress and Unpredictability:
    Rising temperatures and erratic monsoons exacerbate farming uncertainties. For example, delayed October 2023 rains forced compressed harvesting and sowing schedules, making quick field clearance through burning more attractive.

  • Ineffectiveness of Bio-Decomposers:
    Solutions like the Pusa Decomposer suffer from inconsistent field performance, delayed distribution, and lack of farmer training, limiting their large-scale adoption.


What is the Impact of Stubble Burning?

  • Air Pollution in North India:
    Stubble burning peaks during October–November in Punjab, Haryana, and neighboring states, contributing 22–35% of seasonal air pollution (IITs & TERI, 2023).
    Each fire event correlates with a 112.44-unit rise in PM2.5 levels in Delhi-NCR, significantly deteriorating air quality.


Technological Solutions to Tackle Stubble Burning

  • Happy Seeder:
    A tractor-mounted device that plants wheat seeds directly into the paddy stubble, eliminating the need for burning, reducing costs, and improving soil health.

  • Pusa Decomposer:
    A microbial solution that transforms stubble into compost, boosting soil fertility without harming the environment.

  • Pelletization of Crop Residue:
    Conversion of stubble into biomass pellets for energy generation, offering an alternative income stream to farmers.

  • Biochar Production:
    Transforming crop residue into biochar through pyrolysis enhances soil quality, retains water, and supports carbon sequestration.


How Can India Address the Stubble Burning Crisis?

  • Promote Sustainable Crop Diversification:
    Shift incentives towards water-efficient, low-residue crops like millets, maize, and pulses. Guaranteed MSPs, assured procurement, and private sector engagement are essential to make diversification viable and economically secure.

  • Develop Markets for Stubble-Based Products:
    Build robust value chains for fodder, biomass pellets, and eco-packaging materials.
    Integrate collection and processing infrastructure with schemes like MGNREGA and promote Farmer Producer Organizations (FPOs) for market access.

  • Regulatory Frameworks and Incentives:
    Implement a three-tier system:

    • Strict enforcement of anti-burning laws,

    • Permit conditional burning only when unavoidable,

    • Offer subsidies, tax breaks, or direct payments for productive stubble use.

  • Ensure Fair Pricing for Farmers:
    Break the middlemen's monopoly, enhance price transparency, and enable direct market linkages to improve farmer incomes and reduce economic pressures leading to stubble burning.

  • Promote Biofuel and Fertilizer Production:
    Incentivize conversion of crop residues into bio-CNG, ethanol, and organic fertilizers.
    Chhattisgarh’s Gauthan Model exemplifies how community-led initiatives can collect stubble (parali daan) and transform it into eco-friendly fertilizers.

  • Expand Mechanization through Custom Hiring Centres (CHCs):
    Establish CHCs equipped with modern machinery at the village level, supported by mobile booking apps and GPS fleet tracking. Subsidize rental costs to make machines like the Happy Seeder accessible to small and marginal farmers.

  • Form Joint Task Forces:
    Create inter-ministerial task forces across Punjab, Haryana, Uttar Pradesh, and Delhi involving agriculture, environment, rural development, and health sectors. These teams should align national pollution control efforts with grassroots realities, ensuring shared responsibility and coordination.

Geography and Environment(BPSC) (Current Affairs) Resources

Context

  • India has achieved a record of over 145 million tonnes of cargo movement on inland waterways in 2024-25. 

About

  • The number of National Waterways increased from 5 to 111, with the operational length growing from 2,716 km (2014–15) to 4,894 km (2023–24).
    • Massive infrastructure development includes Multi-Modal Terminals (MMTs), Inter-Modal Terminals (IMTs), community jetties, floating terminals, and green tech like Hybrid Electric and Hydrogen Vessels.

cargo movement on national waterways

  • Future Prospects: India aims to increase IWT modal share from 2% to 5%, and raise traffic to 200+ MMT by 2030 and 500+ MMT by 2047 under Maritime Amrit Kaal Vision.

Inland Waterways

  • Inland waterways refer to navigable rivers, canals, backwaters, and creeks used for transportation of goods and passengers within a country. 
  • India has ~14,500 km of navigable waterways, but their usage is limited. 111 waterways have been declared National Waterways (NWs) under the National Waterways Act, 2016.
  • Importance of Inland Waterways
    • Economic Benefits: Lower transportation costs compared to road and rail.
    • Fuel Efficiency: Uses 30% less fuel than road transport and 50% less than rail.
    • Environmental Sustainability: Reduces carbon emissions and congestion on roads.
    • Connectivity: Supports hinterland trade and rural economies.
    • Tourism & Passenger Transport: Plays a role in ferry services and river cruises.

Criteria for Declaring a National Waterway

  • The Inland Waterways Authority of India (IWAI) declares the National Waterway.
  • National Transport Policy Committee (1980) recommended the following criteria for  National Waterway:
    • Navigable by mechanically propelled vessels of reasonable size.
    • Channel width of ~45 m and depth of ~1.5 m.
    • Continuous stretch of at least 50 km.
    • Should serve multiple states, or connect major ports/hinterlands, or be strategically important, or serve underserved areas.
Inland Waterways Authority of India (IWAI)
– Based on recommendations of the National Transport Policy Committee (1980), Inland Waterways Authority of India (IWAI) was established in 1986 under the IWAI Act, 1985.
Ministry: Union Ministry of Ports, Shipping and Waterways.
IWAI Functions:
1. Develop and maintain infrastructure on National Waterways (NWs).
2. Conduct feasibility studies.
3. Recommend declaration of new NWs.
4. Advise Central Government and assist State Governments.

Challenges in Inland Waterway Development

  • Seasonal water level variations affect navigation.
  • Lack of infrastructure (terminals, dredging, and navigation aids).
  • Slow adoption by industries due to underdeveloped routes.
  • Competition from road and rail transport.

Policy Measures to Boost Inland Waterways

  • Jalvahak – Cargo Promotion Scheme: It was launched in 2024 and has two key components:
    • Financial Incentive: Cargo owners get a 35% reimbursement on actual operating costs for shifting cargo from road/rail to IWT, encouraging use of waterways. 
    • Scheduled Services: Regular cargo services have been introduced to boost reliability and predictability. 
  • Extension of Tonnage Tax to Inland Vessels: It was announced in 2025 during the budget, the tonnage tax regime has been extended to inland vessels registered under the Indian Vessels Act, 2021.
    • Benefit: Provides a stable and predictable tax regime based on vessel tonnage rather than profits, thereby lowering the tax burden and encouraging broader adoption of inland shipping. 
  • Regulatory Framework for Private Investment: The National Waterways (Construction of Jetties/Terminals) Regulations, 2025 have been notified, enabling private investment in inland waterways infrastructure.
  • Port Integration:  To ensure seamless multimodal logistics, the Multi-Modal Terminals at Varanasi, Sahibganj, and Haldia, as well as the Intermodal Terminal at Kalughat, are being transferred to Shyama Prasad Mookerjee Port, Kolkata for operation and management.
    • This integration is expected to streamline cargo movement between ports and inland waterways.
  • Digitisation and Centralised Database: A centralised portal is being developed for the registration of inland vessels and crew, similar to the ‘Vahan’ and ‘Sarathi’ systems used for road transport. This initiative will:
    • Simplify registration processes. 
    • Provide real-time data on vessel and crew availability. 
    • Enhance transparency and planning in the sector. 
  • Cargo Aggregation Infrastructure: To resolve issues related to sparse industrial presence along waterways, cargo aggregation hubs are under development:
    • Freight Village at Varanasi.
    • Integrated Cluster-cum-Logistics Park at Sahibganj. 
  • Engagement with Public Sector Undertakings (PSUs): More than 140 PSUs have been engaged to explore shifting a portion of their cargo to IWT. 

Way Ahead

  • The Indian government is investing heavily in inland waterways through projects like Jal Marg Vikas (JMVP).
  • Public-private partnerships (PPPs) are being encouraged.
  • Integration of IWT with multimodal logistics hubs for seamless transport is being carried out.

Yellow Sea
Geography and Environment(BPSC) (Current Affairs) World - Water Bodies

Context: After engaging in similar aggressive posturing in the South China Sea, China is now turning up its game in the Yellow Sea by building a gigantic steel rig.

Interpreting the situation: This development has given China and South Korea a new point of contention.

Learning Zone:

  • The Yellow Sea is a marginal sea of the western Pacific Ocean.
  • Location: Lies between mainland China (west/north) and the Korean Peninsula (east), north of the East China Sea, bounded by the Yangtze River mouth to Jeju Island.
  • It derives its name from the yellowish color of its waters, caused by sand particles from the Yellow River (Huang He) in China.
  • Key Features: Includes Bohai Sea (northwest), Socotra Rock (Ieodo), and numerous islands (e.g., Jeju).
  • Important Ports:
    • China: Tianjin, Qingdao, Dalian
    • South Korea: Incheon
    • North Korea: Nampo

Strategic Importance:

  • Economic Value: Supports fishing (10% of China’s fish catch), potential oil/gas reserves, and major shipping lanes (e.g., Qingdao port).
  • Military Significance: Hosts Chinese naval bases (e.g., Qingdao, PLAN North Sea Fleet) and South Korean assets (e.g., Incheon).
  • Provisional Measures Zone (PMZ): Established in 2001 by China and South Korea to manage overlapping Exclusive Economic Zones (EEZs), allowing joint fishing but prohibiting unilateral structures.

Disputes and Issues:

  • EEZ Overlap: China and South Korea’s 200-nautical-mile EEZs overlap due to the sea’s narrow width (~400 miles), with no finalized maritime boundary despite negotiations since 2015.
  • Socotra Rock (Ieodo): Submerged reef claimed by both (80 miles from South Korea’s Marado, 155 miles from China’s Sheshan). South Korea’s research station (2003) and China’s buoys (2014) fuel tensions.

Indian Economic System(BPSC)

Spaghetti Bowl Phenomenon
Indian Economic System(BPSC) (Current Affairs) External Sector

Spaghetti Bowl Phenomenon and the Complexity of Free Trade Agreements (FTAs)

Context:

  • Ongoing global turmoil over regional trade policies and the proliferation of Free Trade Agreements (FTAs) has reignited concerns about the Spaghetti Bowl Phenomenon.

  • This issue is particularly relevant as India navigates new FTAs and revisits old ones under its renewed foreign trade policy (FTP 2023–28).


What is the Spaghetti Bowl Phenomenon?

Definition:

  • According to the World Bank, the Spaghetti Bowl Phenomenon refers to the confusing, overlapping, and tangled network of bilateral and regional FTAs, making trade processes more complicated rather than facilitating smoother trade flows.

Origin of the Term:

  • Coined by: Jagdish Bhagwati, eminent economist and trade theorist, in 1995.

  • Metaphor:

    • Compares the messy interconnections of different trade rules to a bowl of spaghetti, where intertwined strands represent overlapping FTAs.


Why Does the Spaghetti Bowl Occur?

  • Rules of Origin (RoO):

    • Every FTA comes with its own criteria to define which goods qualify for preferential treatment (reduced tariffs).

    • Problem:

      • Producers dealing with multiple FTAs must comply with different RoOs, increasing administrative burden and compliance costs.

  • Diverse Tariff Schedules:

    • Different FTAs offer varied tariff concessions and schedules, leading to confusion about which agreement offers the best trade terms.

  • Fragmentation of Supply Chains:

    • Multinational companies find it difficult to optimize supply chains when different FTAs impose different origin and compliance standards.


Impacts of the Spaghetti Bowl Phenomenon

Aspect Impact
Trade Costs Increases compliance costs for exporters and importers.
Trade Flows Discourages smaller businesses from utilizing FTAs, leading to stagnant or lower trade volumes despite more agreements.
Inefficiency Creates inefficiencies in global and regional supply chains.
Legal and Bureaucratic Complexity Increases the burden on customs and trade authorities to manage multiple overlapping agreements.
Stagnation in Regional Trade For example, South Asia and East Asia, despite having multiple FTAs, see relatively low intra-regional trade compared to regions like the EU or NAFTA (now USMCA).

Global Examples Illustrating the Phenomenon:

  • Asia-Pacific Region:

    • Over 400+ FTAs either signed, under negotiation, or proposed (as of 2025).

    • Example: ASEAN countries often have bilateral FTAs both with each other and with external partners (like China, Japan, South Korea), creating significant overlaps.

  • Latin America:

    • Proliferation of FTAs among MERCOSUR, Pacific Alliance, and individual countries like Chile and Peru further complicates regional trade.

  • India's Experience:

    • India is part of multiple agreements (like ASEAN-India FTA, India-UAE CEPA, India-Australia ECTA) — leading to challenges in harmonizing trade compliance and maximizing FTA utilization.


Efforts to Overcome the Spaghetti Bowl Effect

Solution Explanation
Mega-regional Agreements Initiatives like RCEP (Regional Comprehensive Economic Partnership) or CPTPP (Comprehensive and Progressive Agreement for Trans-Pacific Partnership) attempt to unify rules under a larger umbrella.
Harmonization of Rules of Origin Simplifying and standardizing RoO criteria across agreements.
Trade Facilitation Agreements WTO's Trade Facilitation Agreement (TFA) encourages simplification of customs procedures.
Digital Tools Creation of FTA portals for exporters/importers to easily navigate different rules (e.g., India’s FTA Utilization Portal under the DGFT).

Mega Leather Cluster Proposed at Ramaipur, Kanpur
Indian Economic System(BPSC) (Current Affairs) Industry

The Central Government has proposed establishing a Mega Leather Cluster in Ramaipur, Kanpur, to revitalize the city's declining leather sector. This move aims to modernize production, address pollution concerns, and generate employment in a historically significant industry for the region.


Decline of Kanpur’s Leather Industry: Key Reasons

  • Legacy of the Leather City:

    • Kanpur earned the moniker “Leather City of India” during British rule, thanks to its thriving tanning industry, proximity to the Ganga River, and availability of cheap labor.

    • Post the 1857 revolt, industrial growth accelerated, employing over 1 lakh workers across 600+ tanneries.

  • Impact of Demonetisation and Pollution Control (2016–17):

    • Demonetisation (2016):

      • The sudden cash crunch halted operations dependent on cash transactions for raw materials and labor payments.

    • Pollution Control Measures (2017):

      • The Uttar Pradesh Pollution Control Board (UPPCB) imposed a 50% infrastructure reduction mandate.

      • Factories faced a penalty of Rs 12,500 per day for non-compliance, leading to operational halts.

      • Simultaneously, the National Green Tribunal (NGT) flagged toxic pollution — heavy metals like chromium and mercury were found in Ganga waters and local residents' blood samples.

  • Rising Operational Costs:

    • Effluent treatment costs surged from Rs 2 to over Rs 100 per hide.

    • The strict environmental regulations transferred compliance costs onto small and medium tanneries, eroding profits.

    • Closure or downsizing: Out of 600 tanneries, only around 200 remain operational today, causing massive job losses and economic downturn.

Geographical Perspective

  • Kanpur, Uttar Pradesh:

    • Located on the south bank of the Ganga River, Kanpur historically thrived due to its access to water, transportation links, and industrial labor.

    • Part of the Indo-Gangetic plain, which supports diverse industries but faces acute environmental stress.

  • Ramaipur:

    • A suburban locality of Kanpur, chosen for its available land and strategic location with access to major highways and railways, making it ideal for large-scale industrial hubs.

  • Environmental Sensitivity:

    • The Ganga Action Plan and continuous monitoring by the NGT make pollution control an essential component for any future industrial cluster in the area.

Challenges Facing India’s Leather Industry

1. Decline in Exports

  • India's leather and leather goods exports fell by nearly 10% in FY24, largely due to sluggish demand from major markets like the US and Europe.

  • Tamil Nadu, the country's top leather exporter, witnessed an 18% decline, heavily impacting overall national figures.

  • The Russia-Ukraine conflict disrupted the Eurozone economy, further contracting global demand.

2. Threat from Synthetic Substitutes and Innovation Deficit

  • The surge of eco-friendly alternatives — faux leather, cork leather, ocean leather, microfiber, and vegan leather — is steadily eroding leather's traditional market share.

  • These substitutes are cheaper, cruelty-free, and increasingly preferred by environmentally conscious consumers, especially in Europe and North America.

  • India’s slow pace of innovation and limited R&D investment are undermining its global competitiveness.

3. Environmental Compliance and Pollution Burden

  • Tanning is inherently polluting, generating toxic chemical waste such as hexavalent chromium.

  • Many units lack modern effluent treatment facilities, exposing workers to hazardous conditions without adequate protection.

  • Growing regulatory scrutiny around environmental health is forcing the closure of non-compliant tanneries, particularly in hubs like Kanpur and Unnao.

4. Regulatory and Raw Material Constraints

  • Bans on slaughterhouses and restrictions on cattle trade have choked the availability of hides, raising input costs.

  • The GST regime increased operational expenses by 6–7%, disproportionately hurting MSMEs.

  • Stricter NGT and UPPCB norms are raising the compliance burden, leading to shrinking operations.

5. Labour and Skilling Gaps

  • A significant share of the workforce remains untrained and semi-literate, leading to low productivity.

  • Poor health and safety awareness, coupled with low technological adaptability, impedes modernization efforts.


How Can India Revive Its Leather Industry?

Tardigrades
Everyday Science (BPSC) (Current Affairs) Biology

Context: The Axiom Mission 4 will see India, Poland, and Hungary’s first government-sponsored human spaceflight in more than 40 years next month.

Meaning of the context: Among the studies set to be carried out in the mission is ISRO’s Voyager Tardigrades project, which will investigate the revival, survival, and reproduction of tardigrades – creatures that have long fascinated scientists.

Learning Zone:

Water Bears Or Tardigrades

  • Tardigrades are microscopic, eight-legged animals measuring 0.1 to 0.5 millimetres, found across terrestrial, marine, and freshwater environments worldwide, and are renowned for surviving extreme conditions—from arid deserts to the heights of the Himalayas.
  • They can also go without food or water for up to years, although their average lifespan is not more than a decade.
  • Remarkable resilience has enabled tardigrades to survive on Earth for approximately 600 million years and makes them likely to endure significant climatic changes in the foreseeable future.
  • Survival Mechanism – Cryptobiosis:
    • Enter a hibernation-like state by curling into a ball called a tun.
    • They retract legs and head into their cuticle (exoskeleton) and shut down almost all body processes.
    • Resume normal activity when favorable conditions return.

Why is ISRO taking Tardigrades to space?

  • Tardigrades are the only known animals capable of surviving even in the cold vacuum of Space. 
  • In 2007, a crewless Russian capsule on a European Space Agency (ESA) mission exposed some 3,000 tardigrades to the vacuum of space for 10 days, and they were left out there in low-Earth orbit. Over two-thirds of the animals survived the mission and even gave birth to offspring upon returning to Earth.
  • The ISRO project will examine the revival of dormant tardigrades, count the number of eggs laid and hatched during a mission, and compare the gene expression patterns of spaceflown vs. ground control populations. 
  • The research seeks to identify molecular mechanisms of resilience, potentially furthering understanding about the limits of life in extreme environments.

India Achieves Breakthrough in Gene Therapy for Haemophilia
Everyday Science (BPSC) (Current Affairs) Health and Diseases

Context

  • India’s first human gene therapy trial for haemophilia was conducted through a collaboration between Biotechnology Research and Innovation Council’s Institute for Stem Cell Science and Regenerative Medicine (BRIC-inStem) and CMC Vellore.

What is Hemophilia?

  • It is a rare genetic disorder that impairs the body’s ability to control blood clotting or coagulation.
  • This can lead to spontaneous bleeding as well as bleeding following injuries or surgery.
  • Hemophilia is caused by a mutation or change, in one of the genes, that provides instructions for making the clotting factor proteins needed to form a blood clot.
    • These genes are located on the X chromosome. Males have one X and one Y chromosome (XY) and females have two X chromosomes (XX). 
  • Hemophilia can result in:
    • Bleeding within joints that can lead to chronic joint disease and pain.
    • Bleeding in the head and sometimes in the brain which can cause long term problems, such as seizures and paralysis.
    • Death can occur if the bleeding cannot be stopped or if it occurs in a vital organ such as the brain.
  • The following two are the most common:
    • Hemophilia A (Classic Hemophilia): This type is caused by a lack or decrease of clotting factor VIII.
    • Hemophilia B (Christmas Disease): This type is caused by a lack or decrease of clotting factor IX.
  • Treatment: There are 2 main approaches to treatment:
    • Preventative treatment, where medicine is used to prevent bleeding and subsequent joint and muscle damage,
    • On-demand treatment, where medicine is used to treat prolonged bleeding.

Gene Therapy to cure Hemophilia

  • Indian scientists conducted the gene therapy trial for severe hemophilia A.
  • The participants received autologous hematopoietic stem cells (HSCs), which were genetically modified using lentiviral vectors.
  • These modified HSCs are capable of giving rise to blood cells that produce functional Factor VIII protein over a substantial period of time.
    • This approach reduces or eliminates the need for repeated Factor VIII infusions.
Gene Therapy
– It is a technique that uses genes to treat, prevent, or cure diseases by:
1.Replacing faulty genes,
2. Deactivating harmful genes,
3. Introducing new genes to restore health.
Methods of Gene Therapy:
1. Somatic Cell Gene Therapy involves the insertion of therapeutic genes into non-reproductive (somatic) cells. The changes are not heritable and are limited to the individual receiving the treatment.
2. Germline Gene Therapy targets reproductive cells such as sperm or eggs, leading to heritable genetic changes. However, due to ethical and safety concerns, this type of therapy is currently banned in most countries, including India.

A New Method to Estimate Helium Abundance in the Sun
Everyday Science (BPSC) (Current Affairs) Science & Technology

Context

  • A recent study by the Indian Institute of Astrophysics (IIA) has accurately estimated the abundance of helium in the Sun’s photosphere. 

Background

  • Helium is the second most abundant element in the Sun after hydrogen, playing a vital role in its structure and energy dynamics. 
  • To accurately measure its abundance in the Sun’s photosphere has been a long-standing challenge due to the lack of helium spectral lines in the visible range.
  • Traditional methods relied on indirect data from hotter stars, the solar corona and wind, and helioseismology (study of the Sun’s internal oscillations).

The new methodology

  • Researchers analyzed high-resolution solar spectra to study both atomic and molecular spectral lines. 
  • They focused on neutral magnesium (Mg) and magnesium hydride (MgH), as well as neutral carbon (C) and its molecular forms CH and C2.

How does the method work? 

  • The spectral lines of both atomic and molecular forms of magnesium and carbon are dependent on the abundance of hydrogen in the Sun’s photosphere. 
  • Any variation in the helium content directly affects the abundance of hydrogen.
  • If the helium abundance increases, the relative abundance of hydrogen decreases.
    • This reduction in hydrogen availability impacts the formation of molecules like MgH and CH, and also lowers the opacity of the Sun’s photosphere.
Internal Structure of Sun
Core: The Sun’s energy originates in its core through nuclear fusion reactions. With extremely high temperatures and pressures, the core fuses hydrogen into helium, releasing energy.
Photosphere: It has no solid surface but appears as a bright disk due to high gas density blocking deeper visibility.
Chromosphere: Located above the photosphere, this layer is less dense and usually visible only during solar eclipses or with special filters.
Corona: The outermost and most extended part of the Sun’s atmosphere. It consists of very hot, low-density plasma and is visible during total solar eclipses.

Extreme Weather Events Forecasting with AI
Everyday Science (BPSC) (Current Affairs) Science & Technology

Context

  • With rising extreme weather events, Artificial Intelligence (AI) is emerging as a transformative tool to improve prediction accuracy beyond traditional models.

Traditional Model of Weather Prediction

  • Traditional weather forecasting uses numerical weather prediction (NWP) models. 
  • The model simulates atmospheric processes using equations of fluid dynamics and thermodynamics. 
  • These physics-based models input observational data from satellites, radars, and weather stations and require high-performance supercomputers for computation.

Prediction of Weather with AI Models

  • Unlike traditional weather models that rely on the laws of physics, AI-based models begin with data. 
  • These models use machine learning algorithms to identify patterns and learn relationships between input variables—such as temperature, humidity, wind speed—and resulting weather events like cyclones or heavy rainfall. 
  • They do this without any prior knowledge of the physical processes that govern the Earth’s atmosphere.

Advantages of AI Models in Weather Forecasting

  • Ability to Use Big Data: AI models can process massive datasets from satellites, radars, weather stations, and even social media, allowing them to detect subtle signals and trends.
  • Handling of Nonlinear Systems: AI models have the potential to uncover hidden patterns and nonlinear cause-effect relationships among Earth system variables that physics-based models may overlook.
  • Adaptability to Local Conditions: AI allows for region-specific models that account for local geographical, topographical, and climatic factors, improving forecast relevance.
  • Real-time Forecasting: AI is capable of rapid “nowcasting” — forecasting weather within the next few hours — which is crucial for disaster preparedness and urban planning.

Challenges in AI-Based Weather Forecasting

  • Complexity: Weather systems  require sophisticated models to capture their dynamic nature.
  • Human Resource Gap: There is a lack of professionals with interdisciplinary expertise in both meteorology and AI/ML.
    • This hampers the development and deployment of high-quality models.
  • Inadequate Sensor Network: The diverse topography of India necessitates regionally tailored models, but this is hindered by gaps in meteorological infrastructure, leading to poor data availability.
  • Climate Change: AI models trained on today’s climate data may become less effective in a warmer future, as the atmospheric system continues to evolve due to climate change.
  • Data-Related Issues: AI models require large, high-quality datasets to train effectively. However, these are compromised by sensor errors, inconsistencies in format, and spatial-temporal gaps in the data, especially in remote regions.
  • Black Box Nature of AI Models: AI systems, particularly deep learning models, operate as “black boxes”, meaning their decision-making processes are opaque.
    • This hinders trust and interpretability, especially among non-experts and operational meteorologists.

Weather Prediction in India

  • India, at present, depends on satellite data and computer models for weather prediction. The Indian Meteorological Department (IMD) uses the INSAT series of satellites and supercomputers.
  • In India three satellites, INSAT-3D, INSAT-3DR and INSAT-3DS are used mainly for meteorological observations. 
  • Forecasters use satellite data around cloud motion, cloud top temperature, and water vapor content that help in rainfall estimation, weather forecasting, and tracking cyclones.

Initiatives taken to improve the efficiency

  • Mission Mausam: It was launched to upgrade the capabilities of India’s weather department in forecasting, modelling, and dissemination. The objectives of the mission are;
    • Develop Cutting Edge Weather Surveillance Technologies & Systems
    • Implement Next-generation radars, and satellites with advanced instrument payloads
    • Develop improved earth system models, and data-driven methods (use of AI/ML).
  • The ‘National Monsoon Mission’ was set out in 2012 to move the nation over to a system that relies more on real-time, on-the-ground data gathering.
  • The IMD is also increasingly using Doppler radars to improve efficiency in predictions. The number of Doppler radars has increased from 15 in 2013 to 37 in 2023. 
    • Doppler radars are used to predict rainfall in the immediate vicinity, making predictions more timely and accurate.
  • The Ministry of Agriculture & Farmers Welfare have initiated the weather information network and data system (WINDS) under which more than 200,000 ground stations will be installed, to generate long-term, hyper-local weather data. 
Indian Meteorological Department (IMD)
– IMD is an agency of the Ministry of Earth Sciences.
– It is the principal agency responsible for meteorological observations, weather forecasting and seismology.
– It is also one of the six Regional Specialized Meteorological Centres of the World Meteorological Organisation (WMO).
