In the ongoing Aravalli definition case, the Amicus Curiae assisting the Supreme Court of India has alleged that a committee led by the Secretary of the Ministry of Environment Forest and Climate Change (MoEFCC)suppressed the views of the Forest Survey of India (FSI) while recommending a new definition of the Aravalli Range.
About Amicus Curiae is a Latin term meaning “friend of the court.”It refers to a person or lawyer appointed by a court to assist it in deciding a case, especially when the court requires additional expertise, independent opinion, or legal clarification.
Key Allegations by the Amicus Curiae
FSI’s views ignored: The committee report allegedly did not include the FSI’s warning that the proposed definition would exclude most Aravalli hills.
100-metre elevation criterion questioned
The committee proposed defining Aravalli hills as landforms with 100 m elevation above local relief.
FSI reportedly warned that this could exclude nearly 90% of the Aravalli landforms from protection.
Procedural issues in the report: The report was described as “unsigned and undated.”
It was not placed before or approved by the Central Empowered Committee (CEC).
Risk of weaker environmental protection: The definition may exclude many low-height hills, potentially allowing mining or construction in sensitive areas.

The ongoing conflict involving Iran, Israel and the United States in West Asia is expected to disrupt supply chains and trade for India’s gem and jewellery sector, according to the Gem and Jewellery Export Promotion Council (GJEPC).
Why the Industry is Vulnerable
Heavy Dependence on GCC Region
India’s gem and jewellery trade relies strongly on the Gulf Cooperation Council (GCC) countries.
GCC share in India’s exports increased from 14% in FY22 to about 22% in FY25.
During April–December 2025, the share rose to 36%.
Major markets include: United Arab Emirates and Saudi Arabia
UAE as a Key Trade Hub
The UAE plays a crucial role in India’s jewellery trade.
Supplies rough diamonds and bullion to India.
Major centre for diamond trade in Dubai.
Accounts for a large share of gold bar imports to India.
Trade Data Highlights
India’s gem and jewellery exports to GCC grew from $5.1 billion (FY22) to $8.3 billion (FY25).
Imports from GCC rose from $16 billion to $28 billion during the same period.
GCC countries supply over 30% of India’s jewellery imports.

An Iranian warship IRIS Dena was reportedly torpedoed by a US submarine in the Indian Ocean near Sri Lanka after participating in the MILAN 2026 and the International Fleet Review at Visakhapatnam. The incident has sparked debate about the legal framework governing naval warfare in international waters.
Key Legal Framework Governing Maritime Conflict
1. UNCLOS (United Nations Convention on the Law of the Sea)
United Nations Convention on the Law of the Sea regulates maritime zones, navigation rights and ocean governance.
It mainly governs peacetime maritime activities.
It does not directly regulate wartime naval operations.
Notably, the United States is not a signatory to UNCLOS.
2. Law of Naval Warfare
During armed conflict, naval warfare laws operate alongside UNCLOS.
Key principles include:
Warships of enemy states can be legitimate military targets.
The laws of armed conflict at sea regulate blockades, attacks, and treatment of vessels.
3. UN Charter and Use of Force
The United Nations Charter provides rules for the use of force.
Article 2(4): Prohibits the use of force against another state.
Article 51: Allows self-defence in response to an armed attack.
4. UN Security Council Authorization
Under Chapter VII of the UN Charter, the United Nations Security Council can authorise the use of force.
However:
Requires majority approval.
None of the permanent members must use their veto.
Maritime Zones Relevant to the Incident
Territorial Sea – up to 12 nautical miles from coast (full sovereignty).
Exclusive Economic Zone (EEZ) – up to 200 nautical miles where coastal states have economic rights.
High Seas – international waters beyond national jurisdiction. The attack reportedly occurred in the EEZ of Sri Lanka.
[2022] With reference to the United Nations Convention on the Law of Sea, consider the following statements: A coastal state has the right to establish the breadth of its territorial sea up to a limit not exceeding 12 nautical miles, measured from baseline determined in accordance with the convention. Ships of all states, whether coastal or land-locked, enjoy the right of innocent passage through the territorial sea. The Exclusive Economic Zone shall not extend beyond 200 nautical miles from the baseline from which the breadth of the territorial sea is measured. Which of the statements given above are correct? (a) 1 and 2 only (b) 2 and 3 only (c) 1 and 3 only (d) 1, 2 and 3
The ongoing conflict involving Iran, Israel and the United States has pushed up oil prices and disrupted energy supplies. Analysts believe the situation may slow India’s economic growth, while the Reserve Bank of India (RBI) is likely to keep interest rates relatively low.
Key Economic Developments
Oil prices have risen about 15% after the conflict began.
The Indian rupee has hit record lows and bond yields have risen.
Financial markets saw sell-offs in equity, debt and currency markets.
These developments have raised concerns about India’s current account deficit and growth outlook.
Impact on India’s Economy
Slower Economic Growth: Disruption of natural gas supplies from the Middle East may affect sectors such as:
Fertilizers
Power generation
If disruptions last more than four weeks, growth could be affected for at least a quarter.
Oil Price Risk: If crude oil prices stay above $90–95 per barrel for several quarters,
India’s growth may slow from above 7% to around 6.5%.
Pressure on External Balance: Higher oil prices can:
India’s retail inflation was 2.75% in January, near the lower end of RBI’s 2–6% tolerance band.
A 10–20% rise in global oil prices may increase inflation by 25–50 basis points.
Government actions such as holding retail fuel prices steady or reducing excise duties may cushion inflation.
RBI’s Likely Policy Response
RBI had already cut the repo rate by 125 basis points in 2025.
Policymakers may prioritise supporting economic growth rather than raising rates immediately.
However, if oil prices cross $100 per barrel, central banks globally may adopt a more hawkish stance.
[2023] Consider the following statements: Statement-I: In the post-pandemic recent past, many Central Banks worldwide had carried out interest rate hikes. Statement-II: Central Banks generally assume that they have the ability to counteract the rising consumer prices via monetary policy means. Which one of the following is correct in respect of the above statements? (a) Both Statement-I and Statement-II are correct and Statement-II is the correct explanation for Statement-I (b) Both Statement-I and Statement-II are correct and Statement-II is not the correct explanation for Statement-I (c) Statement-I is correct but Statement-II is incorrect (d) Statement-I is incorrect but Statement-II is correct
Health experts and anti-tobacco activists are demanding stricter regulation or a ban on nicotine pouches, which are increasingly being sold online in India. Tamil Nadu’s Directorate of Drugs Control has issued alerts and notices against their illegal sale.
What are Nicotine Pouches?
Small microfiber pouches containing nicotine powder, flavourings and additives.
Placed between the gum and lip, where nicotine is absorbed through the mouth lining.
Do not contain tobacco, but still deliver nicotine directly to the bloodstream.
According to the Centers for Disease Control and Prevention, nicotine pouches dissolve in the mouth and do not require spitting.
Why Experts Are Concerned
Highly Addictive: Nicotine is a highly addictive chemical, especially harmful for youth and pregnant women.
Not Approved for Smoking Cessation: Neither the U.S. Food and Drug Administration nor Indian authorities approve nicotine pouches as a quitting aid.
Health Risks: Possible effects include:
Cardiovascular problems
Gum disease and oral health issues
Increased overall nicotine intake
Some pouches reportedly contain up to 50 mg nicotine, far higher than standard nicotine replacement products.

India has launched a large-scale HPV vaccination campaign for adolescent girls using Gardasil, while the India-made vaccine Cervavac has not yet been included in the national immunisation programme due to ongoing research on its single-dose effectiveness.
HPV Vaccine Campaign in India
India plans to vaccinate 1.15 crore girls aged 14 years.
The campaign currently uses Gardasil-4, developed by Merck.
Vaccination is supported by funding from Gavi.
About the Indigenous Vaccine: Cervavac
Developed through collaboration between:
Department of Biotechnology
BIRAC
Bill and Melinda Gates Foundation
Serum Institute of India
Officially launched in 2022.
Estimated price if procured by government: ₹200–400 per dose (much cheaper than global vaccines).
Why Cervavac is Not Yet in the Programme
Ongoing ICMR Study: The Indian Council of Medical Research is studying whether one dose of Cervavac produces enough long-lasting antibodies. Results expected by 2027.
WHO Recommendation Change: The World Health Organization now allows single-dose HPV vaccination in national programmes. Gardasil already has WHO prequalification for single-dose use, while Cervavac does not yet.
Free Vaccine Supply: India received GAVI support providing limited “free” HPV vaccine doses, encouraging the use of Gardasil initially.
New WHO guidance (2022): Countries may use single-dose schedules to improve coverage and reduce costs.
Single-dose programmes are easier to implement because adolescent girls may not return for the second dose.
Burden of Cervical Cancer in India
Second most common cancer among Indian women.
About 80,000 new cases annually.
Around 42,000 deaths each year.
India accounts for about 20% of global cervical cancer cases.
About HPV (Human Papillomavirus)
A group of viruses spread mainly through sexual contact.
Certain strains such as HPV-16 and HPV-18 cause most cervical cancers.
Vaccination significantly reduces risk.
[2022] In the context of vaccines manufactured to prevent COVID-19 pandemic, consider the following statements: The Serum Institute of India produced COVID-19 vaccine named Covishield using mRNA platform. Sputnik V vaccine is manufactured using vector-based platform. COVAXIN is an inactivated pathogen-based vaccine. Which of the statements given above are correct? (a) 1 and 2 only (b) 2 and 3 only (c) 1 and 3 only (d) 1, 2 and 3
The ceramic industry in Morbi, Gujarat may face a shutdown due to disruptions in natural gas and propane supplies following escalating conflict in West Asia and the closure of the Strait of Hormuz.
Importance of Morbi Ceramic Cluster
Morbi is India’s largest ceramic manufacturing hub.
Around 600 ceramic units operate in the region.
The industry employs 2–4 lakh workers directly and indirectly.
Produces tiles, sanitaryware and vitrified products exported globally.
Why the Industry is Affected
Dependence on Gas-Based Fuel
Ceramic units rely heavily on propane and natural gas for: Firing kilns and Drying processes. About 80% of units use propane as the main fuel.
Disruption of Energy Supplies
Gas shipments from Gulf countries are stuck due to tensions involving Iran, Israel, and the United States. Closure or disruption in the Strait of Hormuz, a critical global shipping route, has interrupted supplies.
Limited Fuel Stocks
Propane stocks: 2–4 days.
Natural gas (CNG) supplies: about one week.
If supplies do not resume soon, the industry may suspend operations within 7–10 days.
[2024] Consider the following statements: Statement-I: Sumed pipeline is a strategic route for Persian Gulf oil and natural gas shipments to Europe. Statement-II: Sumed pipeline connects the Red Sea with the Mediterranean Sea. Which one of the following is correct in respect of the above statements? (a) Both Statement-I and Statement-II are correct and Statement-II explains Statement-I (b) Both Statement-I and Statement-II are correct, but Statement-II does not explain Statement-I (c) Statement-I is correct, but Statement-II is incorrect (d) Statement-I is incorrect, but Statement-II is correct
The World Meteorological Organization has indicated high chances of the development of El Niño in the second half of 2026, after the current **La Niña conditions weaken and transition to ENSO-neutral.
What is El Niño?
El Niño is the warm phase of the El Niño–Southern Oscillation (ENSO).
It is a periodic warming of sea surface temperatures in the central and eastern equatorial Pacific Ocean.
This warming disrupts global atmospheric circulation and affects weather patterns worldwide.
ENSO Phases
El Niño (Warm Phase)
Warmer Pacific Ocean temperatures.
Often linked to weaker monsoon rainfall in India.
La Niña (Cool Phase)
Cooler-than-normal Pacific waters.
Often associated with stronger monsoon rainfall in India.
ENSO Neutral
Neither El Niño nor La Niña conditions.
Currently, La Niña is weakening, and neutral conditions are expected soon.
Impact on India
India receives over 70% of annual rainfall during the southwest monsoon (June–September).
July and August alone contribute more than 50% of seasonal rainfall.
If El Niño develops after July, it could reduce monsoon rainfall and affect agriculture, water supply, and food production.
Key Prelims Points
ENSO occurs in the equatorial Pacific Ocean.
El Niño years often correlate with weaker Indian monsoon, though not always.
Monitoring agencies include IMD and WMO.
ENSO affects temperature, rainfall, cyclones, and global climate patterns.
[2011] La Nina is suspected to have caused recent floods in Australia. How is La Nina different from EI Nino? La Nina is characterized by unusually cold ocean temperature in the equatorial Indian ocean whereas EI Nino is characterized by unusually warm ocean temperature in the equatorial Pacific Ocean. EI Nino has an adverse effect on the southwest monsoon of India, but La Nina has no effect on monsoon climate.
