PM Modi Inaugurates Noida International Airport (Jewar) — Phase 1 Opens

🗞️ Why in News Prime Minister Narendra Modi inaugurated Phase 1 of the Noida International Airport (NIA) at Jewar, Gautam Buddha Nagar, Uttar Pradesh on 28 March 2026, making it the Delhi-NCR region second international airport after Indira Gandhi International Airport.

Project Overview

The Noida International Airport is a greenfield project developed under the Public-Private Partnership (PPP) model by Yamuna International Airport Private Limited (YIAPL), a wholly owned subsidiary of Zurich Airport International AG, in collaboration with the Government of Uttar Pradesh and the Government of India. The 40-year concession agreement commenced on 1 October 2021.

Phase 1 Specifications

Master Plan and Future Expansion

Sustainability Features

The Noida International Airport is designed to be India first net-zero emissions airport. It is the country first large-scale infrastructure project to use Limestone Calcined Clay Cement (LC3), a breakthrough lower-carbon construction material. The airport incorporates renewable energy partnerships and low-carbon construction materials throughout.

Connectivity and Economic Impact

The airport is located along the Yamuna Expressway in Jewar tehsil. It will serve western Uttar Pradesh, parts of Rajasthan, Haryana, and Madhya Pradesh — a catchment area of over 200 million people. The project is expected to generate significant employment and boost real estate, logistics, and tourism in the region.

UPSC Angle

Greenfield airports are developed from scratch on new land (as opposed to brownfield airports that expand existing facilities). The PPP model used here involves the private concessionaire (YIAPL/Zurich Airport International AG) building, operating, and maintaining the airport, while the government provides land and regulatory clearances. The concession model is governed by NITI Aayog PPP guidelines.

CAPF (General Administration) Bill 2026 Introduced in Rajya Sabha

🗞️ Why in News Minister of State for Home Affairs Nityanand Rai introduced the Central Armed Police Forces (General Administration) Bill, 2026 in the Rajya Sabha on 25 March 2026, amid strong opposition from INDIA bloc MPs who argued the Bill undermines a Supreme Court judgment.

What the Bill Covers

The Bill is the first-ever unified legislation for the five major Central Armed Police Forces (CAPFs) — Central Reserve Police Force (CRPF), Border Security Force (BSF), Central Industrial Security Force (CISF), Indo-Tibetan Border Police (ITBP), and Sashastra Seema Bal (SSB). Together, these forces comprise over 10 lakh (1 million) personnel.

Key Provisions

The Bill aims to replace the existing patchwork of separate rules, executive instructions, and ad-hoc practices with a single statutory framework covering recruitment, promotions, cadre review, service conditions, disciplinary procedures, welfare measures, postings, transfers, and grievance redressal.

The Supreme Court Controversy

On 23 May 2025, the Supreme Court delivered a landmark verdict granting Organised Group A Service (OGAS) status to CAPF cadre officers and directed the government to progressively reduce IPS deputation in the forces up to the rank of Inspector General within two years. Critics argue that the CAPF Bill 2026 seeks to achieve through legislation what the government was denied by the court — the preservation of IPS dominance in senior CAPF ranks.

UPSC Angle

The debate touches on key constitutional principles: separation of powers (legislature vs judiciary), Article 312 (All-India Services), and the tension between IPS (an All-India Service under Article 312) and CAPF cadre officers (Group A Central Services). The Bill also raises questions about parliamentary competence — whether Parliament can legislate to override a Supreme Court directive.

Nayara Energy Hikes Fuel Prices — Petrol Up Rs 5.30/L, Diesel Up Rs 3/L

🗞️ Why in News Nayara Energy, India largest private fuel retailer, raised petrol prices by up to Rs 5.30 per litre and diesel by Rs 3 per litre on 26 March 2026, becoming the first company to hike prices after crude oil surged past $106/barrel due to the ongoing West Asia (Hormuz) crisis.

Price Impact

Note: Actual increase varies by state due to differing VAT rates; petrol increase ranges up to Rs 5.30/L in some states.

Why Nayara Moved First

State-run oil marketing companies (OMCs) — Indian Oil Corporation (IOCL), Bharat Petroleum (BPCL), and Hindustan Petroleum (HPCL) — have not yet matched the hike. Private retailers like Nayara, which do not receive government subsidies, are more exposed to international crude price movements. The ongoing disruption in the Strait of Hormuz has pushed Brent crude above $106/barrel — a jump of over 50% since the West Asia conflict escalated on 28 February 2026.

About Nayara Energy

UPSC Angle

India imports 85-88% of its crude oil requirement, making it highly vulnerable to global supply disruptions. The Strait of Hormuz handles approximately 20 million barrels of crude oil per day (~20% of global traded oil). India fuel pricing is governed by a deregulated but politically sensitive system — OMCs technically have pricing freedom but often hold prices steady before elections or during crises.

Matsya 6000 Deep-Sea Submersible Completes Wet Tests in Bay of Bengal

🗞️ Why in News India first crewed deep-sea submersible, Matsya 6000, successfully completed wet tests in the Bay of Bengal off Chennai, marking a major milestone in the Samudrayaan mission under the Deep Ocean Mission.

Test Details

The submersible was lowered to a depth of 10 metres in the Bay of Bengal and underwent eight submersions — half of them crewed — with a three-member crew occupying the 2.1-metre diameter titanium alloy sphere for up to three hours per dive. Engineers evaluated structural integrity, electrical systems, life-support systems, and maneuvering capabilities.

Matsya 6000 Specifications

Samudrayaan and Deep Ocean Mission

The Samudrayaan mission is a flagship programme under India Deep Ocean Mission (DOM), launched in 2021. The total Deep Ocean Mission budget is Rs 4,077 crore over five years. Matsya 6000 aims to explore the Central Indian Ocean for polymetallic nodules (manganese, nickel, cobalt, copper) and study deep-sea biodiversity.

Next Steps

The National Institute of Ocean Technology (NIOT) plans to conduct the first 500-metre dive by May 2026, followed by progressively deeper dives leading to the full 6,000-metre mission.

UPSC Angle

India holds an exploration contract with the International Seabed Authority (ISA) for polymetallic nodules in the Central Indian Ocean Basin (CIOB), covering 75,000 sq km. Only five countries — the US, Russia, France, Japan, and China — have previously operated crewed submersibles at such depths. Success would make India the sixth nation with this capability.

Madhavpur Ghed Fair 2026 Begins in Gujarat — Celebrates Rukmini-Krishna Legend

🗞️ Why in News The five-day Madhavpur Ghed Fair commenced on 27 March 2026 at Madhavpur village near Porbandar, Gujarat, bringing together cultural performers from Gujarat and nine Northeastern states under the Ek Bharat Shreshtha Bharat initiative.

About the Fair

The Madhavpur Ghed Fair is held annually starting on the day of Ram Navami at Madhavpur Ghed, a coastal village near Porbandar in Gujarat. According to legend, Lord Krishna married Rukmini, the daughter of King Bhishmaka of Vidarbha (some traditions say Arunachal Pradesh), at this very site after she eloped with him.

2026 Edition Highlights

Northeast Connection

The Mishmi (Idu Mishmi) tribe of Arunachal Pradesh traces its ancestry to King Bhishmaka and through him to Rukmini. This cultural link between Gujarat and the Northeast is celebrated at the fair through folk dance of the Idu Mishmi tribe, Rukmini-Haran folk theatre from Assam, Khullong Ishei songs from Manipur, and dance-dramas based on Rukmini-Krishna legends from multiple Northeastern states.

UPSC Angle

The Ek Bharat Shreshtha Bharat initiative was launched on 31 October 2015 (Rashtriya Ekta Diwas — birth anniversary of Sardar Vallabhbhai Patel) to promote inter-state cultural exchange and national integration. Madhavpur Ghed Fair exemplifies how mythology and shared cultural heritage can bridge geographical distances between India western and northeastern frontiers.

India Growth Data Controversy — GDP Base Year Revision Sparks Debate

🗞️ Why in News The Ministry of Statistics and Programme Implementation (MoSPI) released a new GDP series on 27 February 2026 shifting the base year from 2011-12 to 2022-23, which revised real GDP growth upward to 7.6% for FY 2025-26 but simultaneously reduced nominal GDP by approximately 3.3% — from Rs 357 lakh crore to Rs 345.47 lakh crore.

The Central Paradox

Key Methodological Changes

The new series introduces “double deflation” for calculating real Gross Value Added (GVA), which adjusts both inputs and outputs separately using their respective price indices. It also includes improved estimates of Private Final Consumption Expenditure (PFCE) and better synchronisation between production-side and expenditure-side estimates through Supply-Use Table (SUT) integration.

International Scrutiny

In November 2025, the International Monetary Fund (IMF) assigned India a “C” rating for its national accounts coverage, explicitly citing concerns over outdated base year data. A Peterson Institute for International Economics (PIIE) working paper published in 2026 estimated that India annual GDP growth may have been overestimated by approximately 1.5 to 2 percentage points over the past 20 years.

Historical Context

The 2015 base year revision (from 2004-05 to 2011-12) was similarly controversial. Manufacturing growth under the new series was recorded at 7.4% annually (2011-2019), compared to just 3.8% recorded by the Index of Industrial Production (IIP) for the same period — a gap of 3.6 percentage points that was never satisfactorily explained.

UPSC Angle

GDP base year revision is a routine statistical exercise undertaken approximately every 10 years to reflect structural changes in the economy. The base year represents the reference point against which prices and output are compared. The controversy highlights the tension between statistical methodology and political economy — growth figures influence sovereign credit ratings, foreign investment flows, and electoral narratives.

Underground Water Reservoir Discovered 700 km Below Earth Surface — 3x Ocean Volume

🗞️ Why in News A study by geophysicist Steven Jacobsen of Northwestern University and seismologist Brandon Schmandt of the University of New Mexico confirmed the existence of a massive underground water reservoir trapped within the mineral ringwoodite at approximately 700 km below the Earth surface, holding water equivalent to roughly three times the volume of all surface oceans.

Key Findings

How Ringwoodite Holds Water

Ringwoodite has a special crystal structure (spinel-type) that attracts hydrogen and traps water within its molecular framework. If just 1% of the weight of mantle rock in the transition zone is H2O, it would equal nearly three times the amount of water in all surface oceans. The water exists as hydroxyl radicals (OH) bound into the mineral crystal structure — a “fourth form” of water beyond liquid, ice, and vapour.

Physical Evidence

A piece of ringwoodite was found inside a diamond brought up from a depth of approximately 660 km by a volcano in Brazil. This tiny sample — the only natural ringwoodite specimen from Earth interior — contained a surprising amount of water bound in solid form.

Significance for Earth Science

The discovery challenges the prevailing “cometary delivery” theory that Earth water was brought by comets during the Late Heavy Bombardment period. Instead, it suggests water may have gradually seeped out from the Earth interior over millions of years. This has profound implications for understanding the global water cycle and the origin of Earth oceans.

UPSC Angle

Earth interior is divided into crust (0-70 km), mantle (70-2,900 km), and core (2,900-6,371 km). The transition zone (410-660 km) lies between the upper and lower mantle and is where olivine transforms into ringwoodite under extreme pressure. Understanding deep-Earth water reservoirs is critical for models of plate tectonics, volcanism, and the long-term water cycle.

📌 Facts Corner — Knowledgepedia

Ringwoodite Water Reservoir:

• Mineral: Ringwoodite (spinel-structured high-pressure polymorph of olivine)
• Location: 525-660 km depth (mantle transition zone)
• Water volume: ~3 times all surface oceans combined
• Water form: Hydroxyl radicals (OH) trapped in crystal lattice
• Discovery: Steven Jacobsen (Northwestern University) and Brandon Schmandt (University of New Mexico)
• Published: Journal Science (2014)
• Method: 2,000 seismographs, 500+ earthquakes
• Physical evidence: Ringwoodite found in diamond from Brazilian volcano

Other Relevant Facts:

• Earth layers: Crust (0-70 km), Mantle (70-2,900 km), Core (2,900-6,371 km)
• Transition zone: 410-660 km depth
• Olivine: Most abundant mineral in upper mantle; transforms to wadsleyite (410 km) then ringwoodite (525 km)
• Late Heavy Bombardment: ~4.1-3.8 billion years ago, period of intense asteroid/comet impacts
• Total surface water on Earth: ~1.335 billion cubic km

Earth Hour 2026 — 20th Anniversary Observed on March 28

🗞️ Why in News Earth Hour 2026 is being observed on Saturday, 28 March 2026 from 8:30 PM to 9:30 PM local time across the world, marking the 20th anniversary of this global environmental movement organised by the World Wildlife Fund (WWF).

Key Details

History of Earth Hour

Earth Hour began on 31 March 2007 in Sydney, Australia, when 2.2 million people switched off their lights for one hour to demonstrate concern about climate change. The concept was developed by WWF Australia and advertising agency Leo Burnett Sydney, originally under the working title “The Big Flick.” By the second year (2008), 50 million people in 35 countries participated, with landmarks like the Golden Gate Bridge and the Colosseum going dark.

2026 Focus

The 20th anniversary edition emphasises moving beyond the symbolic lights-off gesture to taking concrete actions for nature and climate during the hour. WWF highlights the interconnection between climate change and biodiversity loss — nature and climate together form the planetary life-support system providing clean air, fresh water, and food security.

UPSC Angle

Earth Hour is a soft-power environmental awareness campaign with no binding legal obligations. It is distinct from legally binding climate frameworks such as the Paris Agreement (2015), Kunming-Montreal Global Biodiversity Framework (2022), and the UNFCCC process. However, it plays a significant role in building public consciousness and political will for environmental action.
