May 28 is celebrated every year as World Dugong Day.
About Dugongs:
- Species Info: Dugong dugon, also known as sea cows, are herbivorous marine mammals closely related to manatees but live only in saltwater.
- Habitat: They live in shallow coastal waters and are mainly found in the Andaman and Nicobar Islands, Gulf of Mannar, Palk Bay, and Gulf of Kutch.
- Diet and Role: Dugongs feed on seagrass species like Cymodocea, Halophila, Thalassia, and Halodule. As they graze, they stir up the seabed, earning the nickname “farmers of the sea.”
- Lifespan and Behaviour: They can live up to 70 years and are usually solitary or seen in mother-calf pairs.
- Reproduction: Females mature at 9–10 years and give birth every 3–5 years, resulting in a slow population growth of about 5% per year.
- Conservation Concern: India’s dugong population has dropped to an estimated 200 individuals, with shrinking range and numbers.
Conservation Efforts in India:
- IUCN Status: Dugongs are listed as ‘Vulnerable’ globally and ‘Regionally Endangered’ in India.
- Legal Protection: They are protected under Schedule I of the Wild Life (Protection) Act, 1972.
- Global Agreements: India joined the Convention on Migratory Species in 1983 and signed the Dugong Conservation MoU in 2008.
- Dugong Reserve: In 2022, India established its first Dugong Conservation Reserve in Palk Bay, Tamil Nadu, covering 448.3 sq. km.

[UPSC 2024] What is disaster resilience? How is it determined? Describe various elements of a resilience framework. Also mention the global targets of the Sendai Framework for Disaster Risk Reduction (2015- 2030).
Linkage: The heat health crisis falls under the broader domain of disaster risk reduction and building resilience, especially considering extreme heat events as climate-induced disasters. It prompts discussion on defining resilience and the frameworks needed, aligning with the call for embedding heat resilience into public health systems. |
Mentor’s Comment: India is going through a serious climate-health crisis as rising temperatures and frequent heatwaves put more pressure on the already stretched public health system. At the recent national conference “India 2047: Building a Climate-Resilient Future,” experts shared not only scientific facts like wet-bulb temperatures but also the real-life struggles of informal workers. This showed how heat stress and social inequality are closely linked. The conference highlighted the need to move beyond isolated emergency care and take united, cross-sector, and fair action to build climate resilience into the way we manage public health.
Today’s editorial discusses the serious climate-health crisis as rising temperatures and frequent heatwaves. This content would help in GS Paper II ( Governance & Health Sector) and GS Paper III (Climate change impact).

As extreme weather increases, we need to move from only treating emergencies to preventing problems by focusing on fair and caring public health.
Why is linking weather alerts with health systems crucial?
- Enables Timely Preventive Action: Early warning systems allow health workers to prepare and respond before heatwaves lead to medical emergencies. Eg: In Ahmedabad, heat alerts trigger distribution of hydration kits and public advisories, reducing heatstrokecases.
- Strengthens Community-Level Response: Alerts shared through ASHA workers or local networks can activate door-to-door checks, especially for the elderly and chronically ill. Eg: ASHAs sending WhatsApp messages and visiting vulnerable residents during red alerts.
- Reduces Burden on Emergency Healthcare: By preventing illness through early interventions (like avoiding midday work, increasing hydration), the pressure on hospitals and emergency services is reduced. Eg: Pre-monsoon planning with meteorological inputs helps health centers stock cooling kits and prepare treatment spaces.
What is the impact of extreme heat on India’s public health?
- Rise in Heat-related Illnesses and Deaths: Extreme heat leads to heatstroke, dehydration, and worsens heart and kidney conditions. Eg: According to the National Centre for Disease Control (NCDC), over 25,000 heat-related deaths were recorded in India between 1992 and 2020.
- Overburdened Healthcare Infrastructure: Hospitals face a surge in emergency cases during heatwaves, straining limited resources. Eg: During the 2022 heatwave, Delhi’s Lok Nayak Hospital reported a 30% increase in patients with heat-related symptoms in just a week.
|
How does extreme heat act as a “social injustice multiplier”?
- Greater Risk to Vulnerable Populations: Outdoor workers, elderly, and slum dwellers suffer disproportionately due to poor shelter and exposure. Eg: A study by the Indian Institute of Public Health (Ahmedabad) found construction workers had a 2.5 times higher risk of heat illness compared to the general population during peak summer.
- Limited adaptive capacity: Daily wage workers, street vendors, and waste pickers cannot afford to stop working during heatwaves, making them more vulnerable to heat stress and illness. Eg: Construction workers under tin roofs suffer intense heat but have no choice but to continue working.
- Excludes the marginalised from public guidance: Advice like “stay indoors” or “avoid exertion” is often irrelevant to those who lack shelter, depend on outdoor jobs, or live in overcrowded spaces, highlighting deep systemic inequalities. Eg: A homeless person or a street vendor cannot follow “stay indoors” guidance during a red alert.
Who can act as frontline heat-safety champions?
- ASHA Workers and Primary Health Workers: Trained Accredited Social Health Activists (ASHAs) and staff at Primary Health Centres (PHCs) are well-placed to spread awareness, monitor vulnerable groups, and respond early to heat-related illnesses. Eg: An ASHA worker in a rural village sends heat alerts via WhatsApp and conducts door-to-door visits during a heatwave.
- Health and Wellness Centre Staff: Staff at Health and Wellness Centres can play a key role in educating communities, distributing hydration kits, and advising on preventive measures like staying hydrated and avoiding midday sun. Eg: A nurse at a wellness centre trains local youth on recognizing signs of heat stress and first-aid response.
What are the steps taken by the Indian Government?
- Development of Heat Action Plans (HAPs): The government, in collaboration with local bodies and NGOs, has promoted city-level Heat Action Plans to reduce heat-related mortality through early warnings, public awareness, and cooling strategies. Eg: The Ahmedabad Heat Action Plan (2013) includes early warning systems, public cool spaces, and training for health workers.
- Integration with Meteorological Services: India Meteorological Department (IMD) provides heat alerts, which are increasingly being integrated into local health response systems to trigger preventive action. Eg: Heat alerts in Odisha are linked to ASHA worker messaging and hydration kit distribution before peak summer.
- Policy Push for Climate-Resilient Health Systems: The National Action Plan on Climate Change and Human Health (NAPCCHH) encourages health systems to be climate-ready by building infrastructure, developing clinical protocols, and training staff. Eg: Health ministries now issue advisories on heat stress, including guidance on modifying medication for chronic patients during heatwaves.
|
What preventive steps can make India’s health system heat-resilient? (Way forward)
- Strengthening Primary Health Infrastructure: Equip primary health centres, Health & Wellness Centres, and ASHA workers with training and protocols to identify and respond to heat-related illnesses. Eg: Trained ASHA workers in rural Gujarat conduct door-to-door checks during heat alerts and share hydration tips via WhatsApp groups.
- Integrating Heat Risk into Chronic Disease Care: Clinicians should adjust medications, provide heat safety counselling, and track high-risk patients like those with heart or kidney conditions during summer. Eg: In Delhi, doctors monitor diabetic patients more closely during red alerts and advise them on avoiding midday exposure.
- Standardising Clinical Protocols for Heat Illness: Create and implement national clinical guidelines for diagnosing and treating heatstroke and heat stress, including summer drills and heat corners in hospitals. Eg: Rajasthan hospitals now stock cooling kits and have designated heat response units during summer months.

In 2024, a soundtrack was released inspired by the Laschamps event, a magnetic flip-flop that occurred 41,000 years ago when Earth’s magnetic field weakened to just 5% and the poles briefly reversed.
What is Magnetic Flip-Flop?
- Definition: A magnetic flip-flop is when Earth’s magnetic poles reverse, with the north and south poles switching places.
- Magnetic Field Source: Earth’s magnetic field is generated by the movement of molten iron in the outer core, acting like a giant magnet.
- Reversal Types:
- A long-term change is called a geomagnetic reversal.
- A short-lived, temporary switch is a geomagnetic excursion.
- Field Behavior: During a reversal, the magnetic field weakens significantly and the direction of field lines flips.
- Occurrence: These events are irregular and unpredictable.
Recent Magnetic Reversals and Excursions:
- Last Major Reversal: The Brunhes–Matuyama reversal occurred about 780,000 years ago.
- Known Excursions:
- Norwegian-Greenland Sea event (~64,500 years ago)
- Laschamps excursion (~41,000 years ago), when field strength dropped to 5% of today’s level
- Mono Lake excursion (~34,500 years ago)
- Indian Evidence: Excursions found in Uttarakhand (Bagwalipokar), dated to 15,500–14,700 years and 8,000–2,850 years ago.
- Pole Movement: Since 1831, the north magnetic pole has shifted 1,100 km toward Siberia and now moves at 35 km/year, while the south pole is more stable.
Implications of Magnetic Flip-Flop:
- Radiation Exposure: A weaker magnetic field during flip-flop allows more cosmic radiation, affecting:
- Satellites and astronauts
- Navigation and communication systems
- Power grids and electronics
- Protective Shield: Earth’s atmosphere still protects against harmful radiation even when the magnetic field is weak.
- Climate & Ozone Effects: Events like Laschamps may have altered the ozone layer and climate, but no confirmed link to mass extinctions.
- South Atlantic Anomaly: A current weak-field region affecting spacecraft over South America and South Africa.
- Monitoring Tools: Scientists use satellites, ice cores, volcanic rocks, and geomagnetic observatories to track field changes.
- Global Guidance: The World Magnetic Model, updated every 5 years, supports navigation systems worldwide.
- Prediction Outlook: Though timing of future reversals is uncertain, computer models and cosmic data are improving forecasts.
| [UPSC 2017] Consider the following statements:
1. The Earth’s magnetic field has reversed every few hundred thousand years.
2. When the Earth was created more than 4000 million years ago, there was 54% oxygen and no carbon dioxide.
3. When living organisms originated, they modified the early atmosphere of the Earth.

Scientists have discovered a new sea creature from the Cambrian period named Mosura fentoni, found in Canada’s Burgess Shale, one of the most important fossil sites in the world.
About Mosura fentoni:
- Discovery Site: Mosura fentoni was discovered in Canada’s Burgess Shale, a well-known Cambrian fossil site.
- Biological Group: It belongs to radiodonts, an extinct group of marine predators related to insects, crabs, and spiders.
- Size and Structure: The creature is very small (1.5 to 6 cm) but has a long, complex body made of 26 segments.
- Body Zones:
- The neck supports the head.
- The mesotrunk has six paddle-shaped flaps for swimming, like mini propellers.
- The posterotrunk has up to 16 segments with rows of thin gills and small flaps.
- Breathing Adaptation: The gills in the posterotrunk likely acted as a breathing zone, similar to the tails of horseshoe crabs that help collect oxygen.
Evolutionary Importance:
- Arthropod Evolution: The find helps explain how early arthropods (like modern insects and crustaceans) evolved diverse forms.
- Advanced Abilities: Despite its small size, M. fentoni had specialised swimming and breathing systems.
- Evolutionary Position: It is placed near the base of the hurdiid family in the radiodont family tree.
- Segment Specialisation: Its body shows early examples of segment division for specific tasks — a trait common in modern arthropods.
- Key Insight: The discovery suggests that complex body planning in arthropods began much earlier than previously thought.
Back2Basics: Cambrian Period:
- The Cambrian Period is a division of the geologic time scale that lasted from approximately 541 million to 485 million years ago.
- It is the first period of the Paleozoic Era and follows the Precambrian Eon.
- It is significant because it marks a time when most major animal groups first appeared in the fossil record.
- This period is characterized by the development of complex, multicellular life, especially in marine environments.
- The Cambrian Explosion refers to a relatively short evolutionary event—occurring around 541 million years ago—during which a vast number of new animal species and body plans rapidly emerged.
- Within about 20 to 25 million years, nearly all major animal phyla (like arthropods, mollusks, and chordates) appeared.
- This explosion of biodiversity is seen as one of the most important evolutionary events in Earth’s history.

Researchers have solved the genetic mysteries behind Mendel’s Experiments on Inheritance, using advanced DNA sequencing and genome analysis.
About Mendel’s Experiments on Inheritance:
- Who Was Mendel: Gregor Mendel was an Austrian monk who studied pea plants starting in 1856 to find out how traits like height or color are passed from parents to children.
- Years of Study: He worked for 8 years and tested over 10,000 plants. His results were shared in 1865 but ignored at the time.
- Rediscovered Later: In 1900, other scientists realised how important Mendel’s work was.
- What He Studied: He looked at 7 traits in peas – Seed shape, seed colour, flower colour, pod shape, pod colour, flower position, and plant height.
- What He Found: Some traits (like round seeds) are stronger than others (like wrinkled seeds). These stronger traits usually show up in the next generation.
- Why It Matters: Mendel showed that traits are passed through tiny units called genes, and each gene can have different versions called alleles. This became the foundation of genetics.
What the Study Found (2024):
- What Scientists Did: In April 2024, scientists studied the DNA of 697 types of pea plants to understand the exact genes behind all 7 traits that Mendel studied.
- Big Data: They used powerful machines to look at a huge amount of data — as much as 14 billion pages of information!
- Surprising Results: They found that the pea plant family is more mixed than expected, with 8 different genetic groups due to crossbreeding.
- New Genetic Details:
- Pod color changes due to a missing piece of DNA.
- Pod shape is controlled by 2 specific genes.
- Flower position changes with a small DNA change.
- More Than Mendel: They also found 72 other traits related to seeds, pods, leaves, and roots.
- Why It’s Useful: These findings can help farmers grow better crops, protect plants from diseases, and prepare for climate change.

Recently, India’s Operation Sindoor has put the spotlight on the evolving nature of India and Pakistan’s defence procurement strategies.
What is the situation of India’s defence import pattern?
- Russia’s share in Indian defence imports has decreased from 96.5% in the 1990s to 75% in the 2020s.
- India now imports over 9% from France, 5.5% from the UK, nearly 5% from Israel, and 3% from the US. Over 55% of India’s air-power weapons in the 2020s have come from France, the UK, and Israel, indicating greater reliance on Western technology in a critical combat domain.
|
Why is India moving away from Russia?
- Strategic Diversification: To avoid overdependence on a single supplier, India is diversifying defence partnerships. Eg: India’s growing defence ties with France (e.g., Rafale jets) and the U.S. (e.g., Apache helicopters, Predator drones).
- Technological Advancement and Reliability: Western nations and Israel offer more advanced, precise, and reliable weapon systems. Eg: Israeli-origin SkyStriker drone used in Operation Sindoor reflects a shift toward high-tech partners.
- Geopolitical and Logistical Concerns: Sanctions on Russia post-Ukraine war have raised concerns about timely deliveries and spare parts. Eg: India faces delays in Russian S-400 missile system deliveries due to global sanctions and supply chain disruptions.
What types of foreign weapons did India and Pakistan use during Operation Sindoor?
- India’s Use of Israeli and Russian Weapons: India deployed Israeli-origin weapons like the SkyStriker drone and Russian-made systems such as the Pechoraand OSA-AK missiles. Eg: The SkyStriker was used for precision strikes, while Pechora missiles were used for air defence.
- Pakistan’s Use of Chinese and Turkish Systems: Pakistan used Chinese-origin PL-15 missiles and Turkish-origin Unmanned Aerial Vehicles (UAVs). Eg: PL-15, a long-range air-to-air missile, reflects Pakistan’s military dependence on China.
|
Why is China now the dominant arms supplier for Pakistan?
- Strategic Partnership and Regional Alignment: China and Pakistan share a strong geopolitical alliance, rooted in regional rivalry with India. Eg: The China-Pakistan Economic Corridor (CPEC) has strengthened military and economic ties.
- Decline of U.S. Defence Cooperation: Pakistan’s ties with the United States have weakened, especially due to shifting U.S. strategic priorities and concerns over terrorism. Eg: The U.S. share in Pakistan’s arms imports dropped from 67% in the 2000s to 0.85% in the 2020s.
- Cost-Effective and Tailored Equipment: China offers affordable, adaptable military technology suited to Pakistan’s needs. Eg: Weapons like the JF-17 fighter jet and HQ-9 air defence systems are co-developed or exported specifically for Pakistan.
Who leads the global arms export market?
- United States – Global Leader: The United States dominates global arms exports, accounting for over 65% of the world’s exports in the 2020s. Eg: U.S. exports advanced systems like F-35 fighter jets, Patriot missile systems, and drones to allies worldwide.
- Russia – Declining Influence: Russia’s share has significantly dropped to around 5% due to factors like the Ukraine war, sanctions, and reduced trust. Eg: Former major buyers like India have reduced reliance on Russian defence supplies.
- China – Minimal Global Share but Focused Exports: China holds less than 2% of global exports but plays a critical regional role, especially with Pakistan. Eg: Nearly 33% of China’s limited arms exports go to Pakistan, highlighting strategic alignment rather than market dominance.
What is the situation of Indian arms exports?
- Emerging Exporter with Limited Share: India is still a minor player in the global arms export market, contributing less than 1% of total global arms exports. Eg: India exports light arms and defence equipment to countries like Vietnam, Myanmar, and African nations.
- Focus on Indigenous Defence Systems: India is boosting domestic production under initiatives like ‘Make in India’ and Defence Export Policy 2020, aiming to become an exporter. Eg: Systems like Akash missile, Pinaka rocket launcher, and BrahMos (jointly developed with Russia) are promoted for export.
|
Way forward:
- Accelerate Indigenous Defence Manufacturing: Expand R&D investment and incentivize private sector participation to develop cutting-edge technologies and reduce reliance on imports. Eg: Fast-tracking indigenous programs like AMCA fighter jet and integrating startups under iDEX (Innovations for Defence Excellence).
- Forge Strategic Export Alliances: Target defence exports through strategic partnerships and defence diplomacy, focusing on friendly nations in Southeast Asia, Africa, and Latin America. Eg: Boost exports of systems like BrahMos and Akash missiles through government-to-government deals and defence expos.

- Dismantling and Worker Safety: It includes drafting of guidelines for safe dismantling, regulatory compliance, and worker safety.
Why is Gujarat suitable for this initiative?
- Solar Manufacturing Hub: Gujarat has the highest number of solar module manufacturers in India, creating a large volume of solar waste needing recycling. Eg: Numerous solar factories in Gujarat produce panels, which eventually generate recyclable waste.
- Large-scale Solar Projects: The state hosts many big solar power plants, leading to significant quantities of end-of-life solar panels. Eg: Gujarat’s extensive solar farms produce damaged or old panels that require eco-friendly disposal methods.
- Government Support: Gujarat’s proactive policies and agency initiatives foster effective recycling infrastructure and standards. Eg: GEDA’s tender for solar waste recycling research demonstrates the state’s commitment to clean energy sustainability.
How serious is the solar waste crisis in India?
- Rapid Growth of Waste: From 100 kilotons in FY2023, India’s solar waste is projected to grow to 340 kilotons by 2030, according to CEEW’s 2024 report.
- Long-Term Projection: The volume is expected to increase 32-fold between 2030 and 2050.
- Panel Lifespan Ending: Panels installed during India’s solar boom (2010–2020) are now nearing the end of their 20–25 year lifespan.
- Infrastructure Deficit: India currently lacks a national solar waste policy, making Gujarat’s move even more critical.
What are the challenges for India in recycling of E-waste?
- Informal Sector Dominance: A large portion of e-waste recycling is handled by informal workers using unsafe methods, leading to health risks and environmental damage. Eg: Informal dismantling often involves burning or acid baths to extract metals, releasing toxic fumes.
- Lack of Infrastructure: Insufficient formal recycling facilities and technology gaps limit efficient and eco-friendly processing of complex e-waste. Eg: Many regions lack certified recycling plants capable of handling advanced electronics like smartphones and solar panels.
- Weak Enforcement and Awareness: Poor enforcement of regulations and low public awareness hinder proper e-waste collection and disposal. Eg: Consumers often discard e-waste with regular trash due to lack of knowledge or convenient drop-off options.
What are the steps taken by the Indian government?
- Implementation of E-Waste Management Rules: The government has enacted regulations like the E-Waste (Management) Rules to ensure proper collection, recycling, and disposal of electronic waste. Eg: Mandatory Extended Producer Responsibility (EPR) requires manufacturers to take back and recycle e-waste from consumers.
- Promoting Formal Recycling Infrastructure: Encouraging the development of certified recycling units with environmentally sound processes to handle e-waste safely. Eg: Setting up authorized e-waste recycling centers that use safe dismantling and recovery techniques.
- Awareness and Capacity Building: Conducting campaigns and training programs to educate stakeholders, including consumers and informal sector workers, about e-waste hazards and management practices. Eg: Government and NGOs organizing workshops for informal recyclers to transition into formal, safer e-waste handling roles.
|
Way forward:
- Strengthen Policy Enforcement and Infrastructure: Ensure strict implementation of e-waste and solar waste management regulations while investing in advanced, formal recycling infrastructure to enable safe, efficient, and large-scale recovery of valuable materials.
- Promote Stakeholder Collaboration and Awareness: Enhance coordination between government agencies, industry, and informal workers through capacity building, incentives, and public awareness campaigns to foster sustainable recycling practices and support circular economy goals.

PYQ Relevance:
[UPSC 2023] Comment on the resource potentials of the long coastline of India and highlight the status of natural hazard preparedness in these areas.
Linkage: India’s geography and physical features, like its coastlines, are often discussed in terms of resources and natural hazards. This question is relevant as it pertains to India’s coastline and is categorized under the Geography subject in GS1. |
Mentor’s Comment: In December 2024, the Union Ministry of Home Affairs revised India’s coastline length from 7,516.6 km to 11,098.8 km, not due to any geographical change, but because of the use of advanced cartographic tools and improved measurement techniques. This revision, made nearly 50 years after the original measurement in the 1970s, demonstrates the coastline paradox — the idea that coastline length increases with more detailed measurement scales. The update has significant implications for maritime security, disaster preparedness, and exclusive economic zone delineation, showcasing how technology redefines our geographic understanding.
Today’s editorial discusses the updated length of India’s coastline and its effects. This information is useful for GS Paper I (Geography), GS Paper II (Policy Making), and GS Paper III (Environment & Disaster Management).
_
Let’s learn!
Why in the News?
The Ministry of Home Affairs updated India’s coastline length to 11,099 km in its 2023–24 report, increasing it from the earlier measurement of 7,516.6 km.
What caused the increase in India’s coastline length?
- Use of High-Resolution Mapping Techniques: Earlier measurements (1970s) used low-resolution maps (1:4,500,000), missing finer features. The updated 2024 figure uses high-resolution charts (1:250,000), capturing detailed coastal geometry. Eg: Narrow tidal creeks and sandbars that were previously omitted are now included.
- Features like estuaries, tidal flats, coastal ridges, and inlets are now accurately mapped. Eg: Island groups like Andaman & Nicobar and Lakshadweep, which were inadequately covered earlier, are now comprehensively included.
|
Why is it hard to measure coastlines accurately?
- Coastline Paradox (Dependence on Scale of Measurement): The measured length of a coastline changes based on the size of the measuring unit (“ruler”). Eg: Using a 200-km ruler smooths over small curves, but a 1-km ruler captures every inlet and estuary, increasing total length.
- Irregular and Dynamic Coastal Features: Coastlines are shaped by natural features like creeks, deltas, estuaries, and shifting sediments, which are not fixed. Eg: River mouths may change shape over time due to erosion or sediment deposition, making boundaries unclear.
- Influence of Tides and Sea-Level Changes: High and low tides alter visible land boundaries, affecting measurements at different times. Eg: Areas that are exposed during low tide but submerged at high tide (like mudflats) may or may not be counted depending on timing.
Which tools were used to update the measurement?
- Electronic Navigation Charts (ENCs): Provided detailed and accurate mapping at a finer scale (1:250,000). Eg: These charts helped capture small features like estuaries and creeks which were missed in older maps (1:4,500,000 scale).
- Geographic Information Systems (GIS): Enabled spatial analysis and integration of various data layers for precise mapping. Eg: GIS combined data from satellites, surveys, and field measurements to create a more accurate coastline outline.
- LIDAR-GPS and Satellite-Based Imaging: Laser-based LIDAR and GPS were used for high-resolution topographic mapping. Eg: Drones and satellite altimetry helped detect elevation and shoreline changes, especially in island regions like Andaman & Nicobar.
How does the revised coastline length impact India’s maritime security and disaster preparedness?
- Enhanced Maritime Surveillance and Border Security: A longer coastline means more area to monitor for smuggling, infiltration, and illegal fishing. Eg: The Indian Coast Guard may need more outposts, vessels, and patrol routes to guard the extended 11,099.8 km coastline.
- Expansion of Exclusive Economic Zone (EEZ): The increased length helps in demarcating a wider EEZ, enabling better control over marine resources. Eg: India can assert rights over fisheries, oil, and gas exploration in a broader sea area.
- Improved Disaster Preparedness and Early Warning: Better understanding of coastal geography aids in creating precise models for cyclones, tsunamis, and storm surges. Eg: Coastal States like Odisha and Tamil Nadu can now develop more accurate evacuation and shelter plans.
- Refined Coastal Regulation and Zoning: Accurate coastline data supports zoning laws to restrict construction in vulnerable areas. Eg: Authorities can update Coastal Regulation Zone (CRZ) norms to better safeguard ecosystems and infrastructure.
- Better Climate Resilience and Adaptation Planning: Updated coastline measurements help assess vulnerability to sea-level rise and erosion. Eg: Low-lying areas in Kerala and island regions like Lakshadweep can be prioritized for climate adaptation projects.
What are the resource potentials of the long coastline of India?
- Fisheries and Marine Biodiversity: India’s coastline supports a vast fishing industry, providing employment and food security. Eg: States like Gujarat and Tamil Nadu have thriving marine fishing sectors contributing to exports and coastal livelihoods.
- Port Infrastructure and Trade: The long coastline facilitates maritime trade through major and minor ports. Eg: Ports like Mumbai, Chennai, and Visakhapatnam are crucial for imports, exports, and shipping connectivity under the Sagarmala Project.
- Offshore Energy Resources: Coastal waters have potential for oil, natural gas, and renewable energy like offshore wind and tidal energy. Eg: Mumbai High is a major offshore oil field, while Gujarat and Tamil Nadu are exploring offshore wind energy projects.
- Tourism and Blue Economy Development: Scenic beaches, islands, and marine ecosystems attract tourism and support the blue economy. Eg: Goa’s coastal tourism and the Andaman & Nicobar Islands’ ecotourism contribute significantly to local economies.
- Aquaculture and Coastal Agriculture: Coastal zones are suitable for shrimp farming, seaweed cultivation, and salt production. Eg: Andhra Pradesh and West Bengal have developed large-scale shrimp aquaculture for domestic and export markets.
What is the status of natural hazard preparedness in the coastal Area?
- Improved Early Warning Systems: India has strengthened early warning capabilities for cyclones and tsunamis through institutions like the Indian National Centre for Ocean Information Services (INCOIS) and IMD. Eg: The Odisha government’s timely evacuation during Cyclone Fani (2019) saved thousands of lives.
- Development of Coastal Infrastructure and Shelters: Construction of cyclone-resistant shelters, embankments, and flood control systems has improved disaster resilience. Eg: The National Cyclone Risk Mitigation Project (NCRMP) has led to the building of multi-purpose cyclone shelters in vulnerable states like Andhra Pradesh and West Bengal.
- Community Awareness and Disaster Drills: Government and NGOs have promoted community-based disaster preparedness, training locals in evacuation procedures and first aid. Eg: Regular mock drills in coastal villages of Tamil Nadu and Kerala help improve response readiness.
|
Way forward:
- Integrated Coastal Zone Management (ICZM) Expansion:Strengthen ICZM plans across all coastal states with real-time monitoring, climate-resilient infrastructure, and ecosystem-based approaches. Eg: Expand initiatives like ICZM Phase II to include mangrove restoration, sustainable livelihoods, and coastal erosion control in states like Kerala and Goa.
- Technology-Driven Risk Mapping and Community-Centric Planning: Deploy AI-powered hazard models, geospatial mapping, and mobile-based alert systems to ensure last-mile connectivity. Eg: Use drone mapping for vulnerable areas in the Sundarbans, and integrate local communities into planning via participatory risk assessments.

Africa Day (May 25) marks the anniversary of the founding of the Organisation of African Unity in 1963.In this context, India’s pivot towards digital diplomacy in Africa marks a significant evolution in South-South development cooperation.
What is the goal of Africa’s Digital Strategy?
- Accelerate socio-economic development by placing digital innovation at the center of growth — e.g., promoting e-governance, digital education, and telemedicine through national digital platforms.
- Enable inclusive and sustainable development by encouraging governments to adopt digital solutions aligned with continental initiatives — e.g., the Smart Africa Alliance supports digital transformation across sectors like health, education, and finance.
|
How is India supporting Africa’s digital shift?
- Sharing Digital Public Infrastructure (DPI): India is sharing scalable and affordable DPI models like Aadhaar (digital ID), UPI (digital payments), and DIKSHA (digital education). Eg: In 2024, the Bank of Namibia partnered with NPCI to develop a UPI-like payment system.
- Technical Collaboration and Capacity Building: India is collaborating with African countries for technical implementation and skills development. Eg: Togo partnered with IIIT-Bangalore to develop a national digital ID system using India’s open-source technology.
- Academic and Institutional Support: India is investing in long-term educational infrastructure to build digital talent. Eg: IIT Madras opened its first overseas campus in Zanzibar, offering courses in AI and Data Science.
- Tele-education and Telemedicine Platforms: Early initiatives like the Pan-African e-Network (2009) provided digital healthcare and education through satellite and fiber-optic systems. Eg: Enabled real-time learning and consultation from Indian institutions across several African nations.
- Promoting Open-Source and Inclusive Models: India promotes DPI as digital public goods, making them open-source and adaptable, unlike proprietary systems. Eg: Ghana linked its payment system to India’s UPI to facilitate fast and inclusive financial transactions.
Why is India’s digital diplomacy seen as distinct from that of countries like China or the U.S.?
- Public Good and Open-Source Model: India promotes its digital platforms as Digital Public Goods (DPGs)—open-source, scalable, and designed for inclusive access, unlike the proprietary models of the U.S. or surveillance-heavy systems of China. Eg: India’s open-source Modular Open-Source Identification Platform adopted by Togo shows its focus on affordability and public benefit.
- Co-development and Capacity Building: India emphasizes partnership over patronage, focusing on skill-building and co-creating solutions rather than just exporting tech or infrastructure. Eg: The IIT Madras campus in Zanzibar trains African students in AI and Data Science, linking digital growth with education and job creation.
- Respect for Local Priorities: India’s approach is non-impositional, engaging with African countries based on their needs without attaching strategic conditions, unlike U.S. or China’s often interest-driven engagements. Eg: Countries like Ghana and Zambia adopted India’s DPI voluntarily because it suited their national digital goals—not due to debt obligations or geopolitical pressure.
What challenges block Africa’s digital growth?
- High Cost of Digital Access: Expensive data and devices make it difficult for many people, especially in low-income and rural areas, to access digital services. Eg: In several African countries, mobile data costs over 5% of average monthly income, limiting internet usage.
- Digital Divide and Inequality: There is a significant rural-urban gap in internet connectivity and a gender gap in digital access and literacy. Eg: Women in sub-Saharan Africa are 37% less likely than men to use mobile internet, widening socio-economic disparities.
- Weak Energy Infrastructure: Reliable electricity is essential for digital services, but many African regions lack consistent power supply, slowing digital infrastructure deployment. Eg: In countries like Nigeria, frequent power outages disrupt digital services and internet reliability.
Way forward:
- Enhance Affordable Access: Invest in low-cost internet infrastructure and subsidize digital devices to bridge the digital divide, especially in rural and underserved communities.
- Strengthen Energy and Digital Infrastructure: Expand renewable energy solutions and resilient digital networks to ensure reliable connectivity and power for sustained digital growth.

India achieved record exports of $820.93 billion in FY25, rising 6.5%, but faced growing trade deficits as agriculture lagged, growing only 2.3% yearly despite employing half the workforce.
What was India’s trade performance in FY25?
- Total exports (goods + services) reached $820.93 billion, marking a 6.5% increase over FY24.
- Merchandise exports contributed $437.42 billion (53% of total exports), while services exports contributed $383.51 billion (47%).
- Imports grew by 6.85% to $915.19 billion, with merchandise imports at $720.24 billion (79%) and services imports at $194.95 billion (21%).
- The trade deficit widened to $94.26 billion from $78.39 billion in FY24.
- The trade-to-GDP ratio stood at a robust 41.4%, reflecting India’s deeper integration with global markets.
How will Trade deals bring opportunities for Indian agriculture?
- Reduced Dependence on Price-Sensitive Markets: Trade deals open new and stable markets for Indian agricultural exports, reducing over-reliance on traditional destinations and shielding against price volatility. Eg: The India-UK FTA could boost exports of premium products like Basmati rice, tea, spices, and processed foods to the UK, which is a high-value market with established Indian diaspora demand.
- Boost Processed Agricultural Exports: Trade agreements typically reduce tariffs and non-tariff barriers, enhancing competitiveness of value-added and processed agri-products, which fetch higher margins. Eg: Under the India-UK FTA, processed foods and marine products can gain better access, enhancing India’s earnings from exports of ready-to-eat meals, seafood, and organic food products.
|
Why did agri-export growth slow down over the last decade?
- Frequent Export Bans and Restrictions: Domestic policies often imposed export bans or curbs on essential commodities like rice, wheat, sugar, and onions to control inflation, disrupting export momentum. Eg: Restrictions on broken rice exports and duties on Basmati rice led to a 27% fall in rice export volume in FY24.
- Global Price Fluctuations: Agri-exports are heavily influenced by global price trends — when world prices fall, Indian exports lose competitiveness and earnings. Eg: Rice export values declined despite volume recovering after lifting restrictions, due to price volatility.
- Declining Productivity and Competitiveness: Lack of investment in research, technology, and resource-efficient farming practices lowered growth compared to earlier periods of rapid expansion. Eg: Average annual agri-export growth dropped from 20% (FY05–14) to just 2.3% (FY15–25).
How did rice export restrictions impact trade and prices?
- Export Volume Decline: Restrictions like export bans, duties, and minimum export prices caused a sharp drop in rice export volumes. Eg: Rice exports fell by 27% from 22.3 million metric tonnes (MMT) in FY23 to 16.3 MMT in FY24.
- Global Price Spike: Reduced supply due to restrictions pushed up global rice prices, affecting international markets. Eg: Imposition of export duties and minimum export price (MEP) on Basmati rice led to a spike in global rice prices.
- Value Impact Less Severe than Volume: Despite the fall in export volume, the value of exports dropped only slightly because of higher prices. Eg: Rice export value fell by only 6% even as volumes dropped 27%, showing price effects cushioned revenue loss.
What are the environmental risks of rice exports?
- Water Resource Depletion: Rice cultivation requires large amounts of water, which can strain local water supplies. Eg: In regions like Punjab, intensive rice farming has led to groundwater depletion and lowered water tables.
- Methane Emissions: Flooded rice paddies emit methane, a potent greenhouse gas contributing to climate change. Eg: In Southeast Asia, vast rice fields are significant sources of methane emissions impacting global warming.
- Soil Degradation and Pollution: Continuous rice farming with chemical fertilizers and pesticides can degrade soil quality and contaminate water bodies. Eg: Excessive use of agrochemicals in rice fields in Vietnam has caused soil salinization and river pollution.
What is the status of edible oil imports?
- 2022–23 (November–October): India imported approximately 16.5 million metric tons of edible oils, marking a 17% increase from the previous year. This surge was driven by lower import duties on key oils like palm, soybean, and sunflower oils.
- 2023–24 (November–October): Imports declined by about 3.1%, totaling 15.96 million metric tons, due to higher domestic oilseed production and reduced demand amid rising global prices.
The recent reduction in edible oil imports is very small. So, we need to take more steps to further cut down these imports.
How can India cut edible oil import dependence?
- Increase Domestic Oilseed Production: Boost cultivation of oilseeds like groundnut, mustard, sunflower, and soybean through better seeds, irrigation, and farmer support. Eg: The “Oilseeds Production Mission” aims to raise domestic output and reduce imports.
- Promote Sustainable Farming Practices: Encourage crop diversification and intercropping to improve yields and soil health, reducing reliance on imported oils. Eg: States like Madhya Pradesh have successfully adopted intercropping mustard with wheat to increase oilseed production.
- Develop Processing Infrastructure: Invest in modern oil extraction and refining units to enhance local processing capacity and reduce post-harvest losses. Eg: Setting up mega oilseed processing clusters in regions like Rajasthan to strengthen the supply chain and self-reliance.
|
Way forward:
- Strengthen Oilseed Ecosystem: Enhance productivity through quality seeds, MSP support, and targeted R&D under national missions like the Oil Palm and Oilseeds Mission.
- Build Agro-Processing Capacity: Invest in decentralized, modern oilseed processing units to reduce wastage, improve value addition, and boost farmer income.
Mains PYQ:
[UPSC 2023] What are the direct and indirect subsidies provided to farm sector in India? Discuss the issues raised by the World Trade Organization(WTO) in relation to agricultural subsidies.
Linkage: Agricultural subsidies are a key area of contention in international trade negotiations, particularly within the WTO. Trade deals often involve discussions around reducing or reforming subsidies, which presents both a challenge (potential reduction of support for farmers) and an opportunity (creating a more level playing field or accessing new markets if other countries also reduce subsidies) for Indian agriculture.

The Securities and Exchange Board of India (SEBI) is considering a proposal to ease restrictions on short selling in most stocks.
SEBI’s January 2024 proposal to bar short-selling in stocks that are not in the futures and options segment had caused uncertainty.
What is Short Selling?
- Definition: Short selling is a strategy where an investor sells a stock first and buys it later, aiming to profit from a price drop.
- Opposite of Normal Trade: Unlike regular buying (buy low, sell high), short selling works on selling high and buying low.
- How It Works: You borrow the stock from a broker, sell it at the market price, and later buy it back at a lower price to return it.
- Example: If a stock is sold at ₹2,100 and later bought at ₹1,900, the profit is ₹200. If the price rises to ₹2,300 instead, the loss is ₹200.
Types of Short Selling:
- Short Selling in the Spot Market (Cash Segment):
- Shorting is allowed only for intraday trading (buying and selling financial instruments (like stocks) on the same day).
- You must square off the position (buy back the stock) before 3:30 p.m. on the same day.
- If not squared off, it leads to short delivery, where the exchange settles the trade through an auction.
- There may be heavy penalties if the position is not closed on time.
- Short Selling in the Futures Market:
- Here, you can hold your short position overnight or even roll it over to the next month.
- You must deposit margin money, which is generally higher.
- Futures shorting is riskier and is mostly used by experienced traders.
- This type allows more flexibility but involves greater financial commitment.
Risks Associated with Short Selling:
- Unlimited Losses: If the stock price rises sharply, losses are unlimited.
- Short Delivery Risk: Failing to buy back in the spot market can lead to penalties.
- Liquidity Risk: Hard-to-trade stocks may lead to delayed buybacks and losses.
- Margin Requirements: High margin costs in futures trading limit retail participation.
- Market Volatility: Sudden movements may cause unexpected losses.
- Not for Beginners: Due to complexity and high risk, short selling is unsuitable for new investors.
| [UPSC 2025] Consider the following statements:
Statement I: As regards returns from an investment in a company, generally, bondholders are considered to be relatively at lower risk than stockholders.

Why in the News?
The Golaknath case (IC Golaknath v. State of Punjab, 1967) is one of the most important judgments in India’s constitutional history. It was the first time the Supreme Court said that Parliament cannot amend fundamental rights.
About the Golaknath v. State of Punjab (1967) Case:
- Case Name: IC Golaknath v. State of Punjab (1967) is a landmark case in Indian constitutional history.
- Background: The Golaknath family from Punjab challenged the Punjab Security of Land Tenures Act, 1953, which declared their land surplus under land ceiling laws.
- Claim of Violation: They argued the law violated their Fundamental Right to property, protected under Articles 19(1)(f) and 31.
- Ninth Schedule Issue: The Act was placed under the Ninth Schedule by the 17th Constitutional Amendment, making it immune to judicial review.
- Main Legal Question: Could Parliament amend Fundamental Rights under Article 368, or are such amendments invalid under Article 13(2)?
- Arguments: The petitioners claimed Fundamental Rights are sacrosanct, while the government asserted Parliament’s full power to amend the Constitution.
- Supreme Court Verdict: On February 27, 1967, in a 6:5 majority, the Court held that:
- Parliament cannot amend Fundamental Rights.
- Amendments are “law” and subject to Article 13(2).
- The ruling would apply only prospectively, not to past amendments.
- Overruled Judgments: The decision overturned earlier rulings in Sankari Prasad (1951) and Sajjan Singh (1964) that allowed unrestricted amendments.
Legacy of the Golaknath Case:
- Judicial Restraint on Parliament: This was the first case to restrict Parliament’s power to amend Fundamental Rights.
- Judiciary’s Role Strengthened: It reinforced the Supreme Court’s duty to protect civil liberties and limit legislative overreach.
- Prospective Overruling: Introduced the concept to ensure legal stability without undoing past amendments.
- Constitutional Values Upheld: Affirmed that the Constitution has core values that must be protected, especially Fundamental Rights.
Influence on Future Cases:
- Indira Gandhi Election Case (1975): Built upon the idea that democracy is a basic feature of the Constitution.
- Minerva Mills Case (1980): Reaffirmed limits on Parliament’s amending power and emphasised judicial review.
- Foundational Impact: Although later rulings allowed some flexibility, the Golaknath case laid the foundation for the Basic Structure Doctrine.
- Lasting Message: It ensured that Fundamental Rights remain untouchable, securing the heart of Indian democracy against future misuse.
