Sulphur: Critical Input for Fertiliser Production
Economy → Agriculture & Fertilisers; Environment → Minerals & Resources; Geography → Distribution of Resources
Why in News?
Sulphur prices have surged amid disruptions linked to the Russia–Ukraine conflict and West Asia tensions, creating concerns for India’s fertiliser industry. Import prices have risen sharply, affecting the availability and cost of DAP, SSP and complex fertilisers.
About Sulphur
- Symbol: S | Atomic number: 16
- A non-metallic chemical element, naturally occurring as elemental sulphur and in sulphide and sulphate minerals.
- Pure sulphur is a pale-yellow, brittle solid and a poor conductor of electricity.
- In India, occurrences include Puga Valley (Ladakh), Barren Island, Andhra Pradesh, Kerala and Himachal Pradesh.
Why is Sulphur Important for Fertilisers?
The key chain is:
Sulphur → Sulphuric acid → Phosphoric acid → DAP/SSP/Complex fertilisers
Sulphur is required to produce sulphuric acid, which is used to process rock phosphate into phosphoric acid. Phosphoric acid is an essential input for manufacturing DAP and other phosphatic fertilisers.
India consumes around 3.8–3.9 million tonnes (MT) of sulphur annually, of which about 2–2.1 MT is used by the fertiliser industry.
Why Global Supply Matters
- Major sulphur supplies come as a by-product of oil and natural-gas processing.
- Disruptions affecting producers/shipping routes in Russia and West Asia have tightened supplies.
- India’s sulphur import prices have reportedly risen to around $1,100/tonne, compared with a normal range of roughly $150–250/tonne.
- This creates risks for DAP, SSP and NPK/complex fertiliser production, with implications for agricultural input costs.

Nevados de Chillán Volcano: Active Volcanic Complex of Chile
Geography
Why in News?
Chile’s Nevados de Chillán volcanic complex recorded an eruptive pulse on 18 September 2026, producing a column containing volcanic ash and pyroclastic material that rose about 380 metres above the crater. The volcano continues to remain under a Yellow Technical Alert.
About Nevados de Chillán
- Location: Ñuble Region, central Chile, within the Chilean Andes.
- It is a large composite stratovolcanic complex in the Southern Volcanic Zone (SVZ) of the Andes.
- The complex consists of three overlapping main peaks:
- Cerro Blanco (Volcán Nevado) – highest, ~3,212 m
- Volcán Viejo (Volcán Chillán) – ~3,089 m
- Volcán Nuevo – located between the two.
- Its documented eruptive history extends back to the 17th century, while geological evidence indicates much older volcanic activity.
Key Volcanic Features
Nevados de Chillán is particularly associated with:
- Lava-dome growth
- Explosive eruptions
- Pyroclastic activity
- Ash emissions and lava flows
A lava dome forms when viscous lava accumulates around a volcanic vent rather than flowing rapidly away.
Geographical Significance
The volcano lies along the Andean volcanic belt, which is closely associated with the subduction of the Nazca Plate beneath the South American Plate. Subduction generates magma and contributes to the Andes’ extensive volcanic activity.

AASHVAST Lab: Securing Military Electronics from Hidden Vulnerabilities
Science & Technology
Why in News?
The Indian Army is establishing six AASHVAST laboratories across India to screen military drones and, subsequently, CCTV systems for hidden hardware and firmware-level vulnerabilities. One laboratory has already been inaugurated in Delhi, with at least five more planned.
What is AASHVAST?
AASHVAST stands for Assessment and Analysis of Electronic Systems Hardware for Vulnerabilities and Security Threats.
- It is a specialised firmware analysis and validation system developed for the Directorate General of Electronics and Mechanical Engineers (DG EME).
- Developed by QuickPay Pvt Ltd.
- Unlike conventional physical inspection, it examines the software/firmware and embedded systems controlling electronic equipment.
- It can identify around 14 categories of vulnerabilities.
What Does It Detect?
AASHVAST can screen for:
- Hidden or unused codes and commands
- Embedded passwords and encryption keys
- Unauthorised remote-access tools
- Time- or location-triggered malfunctions
- Geospatial vulnerabilities that may prevent a drone from reaching its destination
- Vulnerabilities associated with GPS spoofing/jamming
- Foreign-origin active components and potentially concealed security mechanisms.
The initial focus is on military UAVs/drones, while Army-procured CCTV cameras are expected to be brought under screening later.
Strategic Significance
AASHVAST addresses supply-chain and embedded-system security in defence equipment. Hidden vulnerabilities in firmware could potentially allow external interference or cause equipment to malfunction during operations.
It also supports cyber resilience, operational reliability and Atmanirbhar Bharat by strengthening scrutiny of critical defence electronics.

NdFeB Magnets: Critical Link in India’s Rare-Earth Value Chain
Science & Technology
Why in News?
Neodymium-Iron-Boron (NdFeB) magnets have gained strategic importance amid India’s efforts to develop domestic rare-earth permanent magnet manufacturing. A recent analysis highlighted that India’s challenge is not merely access to rare-earth minerals but the missing midstream capabilities and incomplete mapping of the entire magnet value chain.
What are NdFeB Magnets?
- NdFeB = Neodymium + Iron + Boron.
- They are rare-earth permanent magnets and among the strongest permanent magnets commercially available.
- They combine high magnetic strength, compact size and high power-to-weight efficiency.
- Compared with ferrite, Alnico and samarium-cobalt magnets, NdFeB magnets are particularly valuable where high power and miniaturisation are required.
Major Applications
They are essential in:
- Electric vehicle (EV) motors
- Wind turbines
- Robotics and automation
- Precision machinery
- Electronics
- Aerospace and defence systems
Thus, they are a critical component of both the clean-energy transition and advanced manufacturing.
India’s Magnet Mission
The Union Cabinet approved a ₹7,280-crore Scheme to Promote Manufacturing of Sintered Rare Earth Permanent Magnets (REPM), targeting 6,000 metric tonnes per annum (MTPA) of integrated domestic manufacturing capacity.
The strategic value chain is:
Rare-earth resources → Mining → Mineral processing → Chemical separation → Nd/Pr oxide → Metal → Alloy → Sintered NdFeB magnet → End-use products
India has also established a Nd-Fe-B magnet pilot plant at ARCI, Hyderabad, covering the process from strip-cast alloy to finished sintered magnets.

Nepal's Climate Call: A Test for India
GS II – International Relations / GS III – Disaster Management
Climate Justice, Regional Cooperation, and Transboundary Disasters
Introduction
Recent catastrophic flash floods across Nepal’s Bhotekoshi and Trishuli river basins—dubbed a “Himalayan Tsunami”—have altered the paradigm of India-Nepal disaster diplomacy. Moving away from charity and ad-hoc relief, Nepal has pivoted to a framework of climate justice and financial liability, appealing to the UN-backed Fund for Responding to Loss and Damage (FRLD) and pressing regional neighbours, including India and China, for cooperation. Nepal’s reconstruction bill is estimated at $4.78 billion—nearly 10% of its GDP. This presents India with a delicate strategic dilemma: as a leading voice of the Global South, India has argued that historical emitters bear sole responsibility for Loss and Damage funding. Yet, as a rising regional power ecologically and economically intertwined with Nepal, India must evolve from a benevolent donor into a structural co-underwriter of regional climate justice.
The Shift in Nepal’s Approach
From Charity to Climate Justice
- Past Paradigm: India as “First Responder”—NDRF teams, airlifted supplies, reconstruction grants.
- New Paradigm: Nepal’s leadership explicitly pivots to climate justice and financial liability.
- Appeal: UN-backed Fund for Responding to Loss and Damage (FRLD); calls on developed countries for compensation and concessional climate finance.
- Regional Cooperation: Pressing China and India for preparedness, data sharing, and resilience.
Diplomatic Escalation
- UN General Assembly (September 24): PM Balendra Shah to raise the case; Nepal hosting a side event on Himalayan climate risk.
- COP31 (Antalya, November): Issue to be taken forward.
The Rationale
- Global Climate Finance Unsuitable: GCF project for GLOF protection sat in pipeline for 7+ years.
- Loss and Damage Fund: Capital reserves a drop in the ocean compared to real-world costs.
- CBDR Applied Locally: Adjacent, high-emitting economic engines share an immediate physical footprint.
India’s Dilemma
The Case Against Liability
- Climate Equity: India’s per capita emissions low; historical contributions minimal.
- Pandora’s Box: Accepting liability could expose India to claims from other South Asian countries and Pacific Island nations.
- Leverage: Weakens India’s position against the Global North.
The Case Against Rejection
- Geopolitical Risk: China expanding climate and ecological diplomacy across the Himalayas.
- Anti-India Sentiment: Evasive stance risks alienating the Nepalese public.
- Strategic Space: Ceding space to Beijing.
Economic Interdependence
- Hydropower Investments: Indian firms invested billions in Arun III, Upper Karnali.
- Mutual Loss: GLOFs destroy dams and cascade downstream into Bihar and Uttar Pradesh.
- Co-Dependent: India is not an outside observer; it is ecologically and economically intertwined.
The Way Forward: A New Paradigm
Establish a Regional Himalayan Risk & Insurance Facility
- Framework: NDB, AIIB, BIMSTEC, or Third Pole Compact.
- Mechanism: Rapid-payout parametric insurance pool; funds released automatically upon satellite detection of threshold climate triggers.
- Benefit: Predictable financial flows; bypasses years of diplomatic wrangling.
Re-engineer Transboundary Infrastructure Investment
- Resilience-First: Dedicated percentage of joint infrastructure budgets into an Ecological Adaptation Fund.
- Focus: Climate-resilient local infrastructure; stabilise upstream slopes; safeguard mountain livelihoods.
Institutionalise Open-Access Transboundary Data
- ISRO Capabilities: Leverage space technology for real-time, open-access early warning system.
- Co-Ownership: GLOF monitoring data and lake volume tracking with Nepalese agencies.
- Transformation: Tactical intelligence into a shared regional security asset.
Middle-Power Leadership
- Innovation: Just as India and China reshaped development finance through NDB, they can innovate on climate cooperation.
- Localised Loss and Damage: Pioneer mechanisms beyond rigid, slow-moving Western models.
- Global South: Demonstrate that commitment begins at India’s own borders.
Conclusion
Nepal’s climate call is a test for India. The Himalayan nation has moved from charity to climate justice, appealing to global funds and pressing regional neighbours for cooperation. India faces a dilemma: accepting liability risks a Pandora’s box; rejecting it risks ceding strategic space to China. Yet India’s economic interests are tied to Nepal’s ecology—hydropower investments, downstream floods. The way forward lies in transcending the false choice between total legal liability and passive relief. India can champion a Regional Himalayan Risk & Insurance Facility, re-engineer transboundary infrastructure, and institutionalise open-access data. By pioneering localised Loss and Damage mechanisms, India can demonstrate a new paradigm of middle-power leadership—proving that its commitment to the Global South begins right at its own borders.
Practice Question
- Nepal’s climate call is a test for India, requiring a shift from benevolent donor to structural co-underwriter of regional climate justice. Critically examine India’s dilemma and suggest a new paradigm for regional climate cooperation. (250 words, 15 marks)

Unsafe Space: On the US and 'On-Orbit Space Control Weapons'
GS III – Science & Technology / GS II – International Relations
Space Security, Arms Control, and Multilateral Governance
Introduction
The admission on September 14, 2026, by US Air Force Secretary Troy Meink—confirmed by Space Force chief Gen. Douglas Schiess—that the US has deployed “on-orbit space control weapons” to “defend against hostile adversary action” is cause for concern. Satellite systems increasingly underpin communications, energy, and financial networks, and many commercial systems serve civilian and military users. The US, Russia, China, and India, among others, have been developing counter-space capabilities while rendering Earth orbit the next major battlefield. The increasing military use of commercial satellites can endanger protections they enjoy under international humanitarian law, even as this law is underprepared for satellites being highly interconnected and often dual-use.
The Weaponisation of Space
US Deployment
- Admission: September 14, 2026; US has deployed on-orbit space control weapons.
- Justification: “Defend against hostile adversary action.”
- Ambiguity: Described as “defensive,” but US military doctrine defines “space control” as encompassing both offensive and defensive operations.
Counter-Space Capabilities
- Developers: US, Russia, China, India, among others.
- Trend: Earth orbit becoming the next major battlefield.
- Commercial Satellites: Increasing military use; dual-use nature; endangers protections under international humanitarian law.
Risks
- Unclear Intentions: Two steerable satellites approaching each other without understanding the other’s intentions.
- Autonomous Satellites: Future AI models onboard could escalate without human intervention.
- Policy Gap: What constitutes “hostile action” and what the weapon can do remain unclear.
The Legal Framework and Its Limits
Outer Space Treaty (1967)
- Article IV: Prohibits nuclear weapons or other weapons of mass destruction in orbit.
- Article III: Requires space activities to comply with international law.
- Gap: Does not ban conventional weapons in orbit per se.
- Fluid Line: Conventional weapons can render damage en masse; satellite-based networks central to society.
Liability Convention
- Limitation: Cannot be applied straightforwardly when an autonomous, dual-use orbital asset operated by a commercial entity initiates an unwanted defensive strike.
- Accountability: Unclear who is responsible.
Need for New Rules
- Too Coarse: Existing rules inadequate for contemporary technologies and declining esteem for a rules-based world order.
- Multilateral Governance: Urgent need for arrangements defining exact thresholds of action and escalation.
Way Forward
UN Open-Ended Working Group
- Opportunity: On ‘Prevention of an Arms Race in Outer Space’ (PAROS).
- Address Disclosure: Governments should address the US disclosure.
US Government
- Reveal Particulars: Details of weapons deployed.
- Enter Multilateral Arrangement: Defining exact thresholds of action and escalation.
Multilateral Governance
- Define Thresholds: What constitutes hostile action; what responses are permissible.
- Autonomous Systems: Rules for AI-enabled satellites.
- Commercial Entities: Clarify accountability for dual-use assets.
- Verification: Mechanisms to monitor compliance.
Conclusion
The US deployment of on-orbit space control weapons raises serious concerns. Space is increasingly militarised, with counter-space capabilities being developed by major powers. The existing legal framework—Outer Space Treaty, Liability Convention—is too coarse for contemporary technologies, especially autonomous, dual-use commercial satellites. The rules have become inadequate for a world where Earth orbit is the next battlefield. The UN Open-Ended Working Group on PAROS should address the US disclosure, and the US government should reveal the particulars of its weapons and enter into a multilateral governance arrangement defining exact thresholds of action and escalation. Multilateral governance in space is no longer optional—it is imperative.
Practice Question
- The US deployment of on-orbit space control weapons calls for multilateral governance in space, as existing rules are too coarse for contemporary technologies. Critically examine the legal and strategic challenges of space weaponisation and suggest measures for multilateral governance. (250 words, 15 marks)
