Current Affairs — 9 September 2026

1. India-Japan Defence Ties: The 'UNICORN' Antenna and the Push for Joint Shipbuilding

Basic Concept

The India-Japan bilateral relationship was elevated to a 'Special Strategic and Global Partnership' in 2014, and defence cooperation under this framework rests on instruments such as the 2+2 Ministerial Dialogue (Foreign and Defence Ministers of both countries, begun in 2019) and the Agreement Concerning Reciprocal Provision of Supplies and Services (ACSA), signed in 2020, which allows the two militaries to share logistics support. A crucial enabler for hardware cooperation is Japan's 'Three Principles on Transfer of Defence Equipment and Technology' (2014), which replaced Japan's earlier blanket ban on arms exports and allows case-by-case transfers to partner countries under strict conditions. This falls under the GS2 syllabus heading of 'India and its neighbourhood' and bilateral relations, and is also relevant to GS3 defence-technology indigenisation debates.

Core Context

Building on an August 2026 bilateral defence ministers' meeting between Rajnath Singh and his Japanese counterpart Shinjiro Koizumi, the two sides have moved to fast-track the shipborne 'UNICORN' integrated communications antenna project for the Indian Navy, which both governments describe as the first actual defence equipment transfer project between the two countries, while also agreeing to explore joint naval shipbuilding and design.

Latest Developments

• UNICORN is a stealth integrated-mast system that houses multiple communication and radar antennas inside a single composite structure, sharply reducing a warship's radar cross-section.
• The project builds on a November 2024 memorandum of understanding involving Bharat Electronics Limited (BEL) and marks Japan's first major defence-equipment transfer to India under its revised Three Principles framework.
• Both sides agreed to maximise synergies on mine-countermeasure capabilities and to explore joint development in naval shipbuilding and design, combining Japan's technological expertise with India's production scale.
• India and Japan also agreed to work toward a reciprocal ship-repair arrangement, allowing each country's navy to access the other's repair facilities.
• The cooperation is billed as part of a wider shift from largely symbolic defence exercises toward genuine operational and industrial convergence between the two Indo-Pacific partners.

UPSC Prelims Pointers

• Japan's 'Three Principles on Transfer of Defence Equipment and Technology' (2014) replaced its earlier near-total ban on arms exports.
• The India-Japan 'Special Strategic and Global Partnership' dates to 2014; the 2+2 Ministerial Dialogue mechanism between the two countries began in 2019.
• ACSA (Agreement Concerning Reciprocal Provision of Supplies and Services) between India and Japan was signed in 2020, enabling logistics-sharing between their armed forces.
• UNICORN is designed to reduce a warship's radar cross-section (RCS), a key stealth parameter in modern naval architecture.

2. The UN's 'Correct the Map' Resolution: Equal-Area Projections and India's Cartographic Position

Basic Concept

Most widely used world maps, including the popular Mercator projection (developed in 1569), preserve angles and shapes for navigation but severely distort relative land area, particularly inflating high-latitude regions (like Europe, Russia and Greenland) while shrinking equatorial regions (like Africa and South Asia). 'Equal-area' map projections, such as the Gall-Peters or the more recent Equal Earth projection, instead preserve the true relative size of landmasses, though they introduce their own shape distortions. Cartographic representation and map distortions are covered under GS1 (Geography - Map reading) and connect to GS2 discussions on global governance and soft power.

Core Context

On 6 September 2026, the UN General Assembly adopted, by a vote of 164 in favour to 1 against (the United States) with six abstentions, a resolution titled 'Correct the Map' calling for wider use of accurate, equal-area cartographic representations of the world; India voted in favour but issued an explanation of vote clarifying that its support was limited to the principle of equal-area representation and did not extend to endorsing any specific map or political boundary depiction.

Latest Developments

• The resolution was adopted on 6 September 2026 with 164 votes in favour, 1 against (United States) and 6 abstentions.
• The initiative especially targets correcting the Mercator projection's distortion of Africa, which appears far smaller on conventional maps than its true landmass relative to Europe, Russia, Greenland and North America combined.
• India's Ministry of External Affairs clarified that its 'yes' vote endorsed only the general principle of equal-area representation and explicitly does not deal with political cartography, international boundaries, or disputed territories.
• India flagged specific concerns regarding any map depictions relating to Jammu and Kashmir, Ladakh and Arunachal Pradesh, reiterating that these remain integral parts of India regardless of any cartographic reform exercise.
• The resolution itself is non-binding and does not mandate an overnight change to maps used in schools, atlases, or official documents worldwide.

UPSC Prelims Pointers

• The Mercator projection (1569), created by Gerardus Mercator, preserves angles/shapes for navigation but distorts relative area, especially at high latitudes.
• The Gall-Peters projection and the newer Equal Earth projection are examples of equal-area map projections that preserve true relative landmass sizes.
• UN General Assembly resolutions adopted under its ordinary procedures are recommendatory/non-binding, unlike UN Security Council resolutions passed under Chapter VII.
• India's territorial positions on Jammu and Kashmir, Ladakh and Arunachal Pradesh remain unaffected by any UN resolution on map projections, since such resolutions explicitly exclude political boundary questions.

3. Swachh Vayu Sarvekshan 2026: Ranking India's Clean-Air Cities

Basic Concept

The National Clean Air Programme (NCAP) was launched by the Ministry of Environment, Forest and Climate Change (MoEFCC) in January 2019 as India's first national-level strategy to tackle air pollution, initially targeting a 20-30% reduction in PM2.5/PM10 concentration by 2024 (base year 2017), later revised to a 40% reduction target by 2025-26. It covers 130-131 'non-attainment' cities that failed to meet the National Ambient Air Quality Standards (NAAQS) over five consecutive years, and funds interventions through the 15th Finance Commission's air-quality grants alongside NCAP-specific funding. The Swachh Vayu Sarvekshan is NCAP's annual ranking exercise, benchmarking city-level performance, and Swachh Vayu Diwas (7 September, coinciding with the UN's International Day of Clean Air for Blue Skies) is its associated observance day. This is core GS3 (Environment, Pollution) content.

Core Context

On Swachh Vayu Diwas 2026 (7 September), MoEFCC conferred the 5th Swachh Vayu Sarvekshan awards recognising the best-performing cities and wards under NCAP, with fresh data showing measurable, sustained PM10 improvement across a majority of participating cities since the programme's 2017 baseline.

Latest Developments

• In the Category-I segment (cities with population above 10 lakh), Lucknow topped the rankings with a score of 198 out of 200, narrowly ahead of Indore (197) and Jabalpur; Delhi ranked 30th in this category.
• 130 NCAP cities were assessed for 2026 across three population-based categories: above 10 lakh, 3-10 lakh, and below 3 lakh.
• 108 of the 130 assessed cities showed an improvement in PM10 levels compared to the 2017-18 baseline; 72 cities recorded a PM10 reduction of more than 20%, and 26 cities recorded a reduction exceeding 40%.
• 14 cities met the National Ambient Air Quality Standards (NAAQS) for PM10 in FY 2025-26, up from just 6 cities in 2017-18.
• Alongside the awards, MoEFCC released a Compendium of Best Management Practices under NCAP, documenting replicable clean-air interventions from top-performing cities.

UPSC Prelims Pointers

• NCAP was launched in January 2019 by MoEFCC, India's first national framework specifically targeting city-level air pollution reduction.
• NCAP's original target was a 20-30% reduction in PM2.5/PM10 by 2024 (base year 2017), later revised to a 40% reduction target by 2025-26.
• 'Non-attainment cities' under NCAP are those that consistently failed to meet NAAQS over five consecutive years.
• Swachh Vayu Diwas (7 September) coincides with the UN's International Day of Clean Air for Blue Skies.

4. Crop Diversification: Moving Beyond the Paddy-Wheat Monoculture

Basic Concept

India's post-Green Revolution agricultural policy has historically incentivised cereal monocropping, particularly the paddy-wheat rotation in states like Punjab and Haryana, through assured Minimum Support Price (MSP) procurement, which has contributed to groundwater depletion, soil-nutrient imbalance and stubble-burning-linked air pollution. 'Crop diversification' refers to a shift in cropping pattern away from this cereal-dominant system toward pulses, oilseeds, horticulture (fruits and vegetables), plantation crops and agroforestry, which typically generate higher gross value added (GVA) per unit of land and water while building climate resilience. This is a recurring GS3 (Economy/Agriculture) and GS1 (Geography, agro-climatic zones) theme.

Core Context

Building on the crop-specific, regionally differentiated diversification strategy announced in Budget 2026-27, the government is pushing high-value horticulture, plantation crops (such as coconut, cashew and cocoa) and agroforestry across India's coastal, North-Eastern and Himalayan agro-climatic zones, positioning horticulture as the cornerstone of a broader shift away from cereal-dominant farming.

Latest Developments

• Budget 2026-27 introduced a regionally differentiated diversification strategy, moving beyond blanket cereal-support policies toward crop-specific incentives tailored to each agro-climatic zone.
• Focus crops identified for expansion include coconut, cashew, cocoa, agarwood, walnuts, almonds, sandalwood and pine nuts, chosen for their export potential and suitability to specific regions.
• Horticulture is being positioned as the cornerstone of the diversification push because it generates higher gross value added (GVA) per hectare and per unit of water compared to cereal cultivation.
• The strategy explicitly targets India's coastal regions, North Eastern states, and Himalayan areas, recognising their distinct agro-climatic advantages for plantation and horticultural crops.
• Key challenges flagged include weak post-harvest infrastructure, price volatility for perishable produce, limited cold-chain and market linkages, and the risk of new dependency cycles replacing the old cereal-MSP dependency.

UPSC Prelims Pointers

• The MSP (Minimum Support Price) system, rooted in the Green Revolution era, is often cited as a structural driver of India's continued paddy-wheat monoculture in northwestern India.
• Gross Value Added (GVA) per hectare is a standard metric used to compare the economic efficiency of different cropping patterns.
• Horticulture in India (fruits, vegetables, spices, flowers) has, in recent years, exceeded foodgrain production by volume, according to Ministry of Agriculture estimates.
• Agroforestry (integrating trees with crops/livestock on the same land) is promoted both for income diversification and for its co-benefits in carbon sequestration and soil health.

5. Anak Krakatau's Eruption: A Reminder of the Sunda Strait's Seismic Volatility

Basic Concept

Indonesia sits astride the Pacific 'Ring of Fire', a horseshoe-shaped belt around the Pacific Ocean accounting for around 75% of the world's active and dormant volcanoes and roughly 90% of global earthquakes, formed by the subduction of oceanic plates beneath continental plates. Anak Krakatau ('Child of Krakatoa') is a volcanic island that emerged in 1927 from the caldera left behind by the catastrophic 1883 eruption of Krakatoa, one of the deadliest volcanic events in recorded history; it sits in the Sunda Strait between the Indonesian islands of Java and Sumatra. This is core GS1 (Geography - Volcanism, plate tectonics) content, with a disaster-management (GS3) angle.

Core Context

In early September 2026, Anak Krakatau produced a continuous eruption lasting roughly 25 hours, ejecting ash high into the atmosphere and disrupting air travel across Indonesia, underscoring the continued volcanic hazard posed by the Sunda Strait region nearly a century and a half after the original 1883 Krakatoa eruption.

Latest Developments

• The continuous eruption began on 4 September 2026 and ended in the early hours of 6 September 2026, lasting about 25 hours.
• Eight airports were closed for safety reasons, with operations disrupted in Jakarta, Bandung and Lampung, and flights to Bali, Medan and Surabaya facing cancellations, delays or diversions; more than 340,000 travellers were affected.
• Volcanic ashfall affected populated areas to the east of the volcano, including parts of Jakarta and West Java, posing respiratory, eye and skin health risks.
• Anak Krakatau has since reverted to its more typical Strombolian eruption pattern (intermittent ejection of volcanic material) and remains at Alert Level III, the second-highest tier on Indonesia's four-level volcanic warning scale.
• The volcano itself formed in 1927 within the caldera created by the 1883 Krakatoa eruption, which killed over 36,000 people, generated tsunamis felt across the Indian Ocean, and produced global climatic effects for several years afterward.

UPSC Prelims Pointers

• The Pacific 'Ring of Fire' accounts for about 75% of the world's active/dormant volcanoes and about 90% of all earthquakes.
• Anak Krakatau ('Child of Krakatoa') emerged in 1927 from the caldera of the 1883 Krakatoa eruption, located in the Sunda Strait between Java and Sumatra.
• A 'Strombolian eruption' is a type of volcanic activity characterised by intermittent, relatively mild explosive bursts, named after the Italian volcano Stromboli.
• Indonesia uses a four-level volcanic alert scale; Level III (Siaga/Watch) is the second-highest tier, below Level IV (Awas/Warning).

6. Boma-Badingilo Migratory Landscape: South Sudan's First World Heritage Site

Basic Concept

The UNESCO World Heritage Convention (1972) allows sites of 'outstanding universal value' to be inscribed on the World Heritage List under natural, cultural or mixed criteria; a separate mechanism, the List of World Heritage in Danger, flags sites facing serious threats requiring urgent international assistance, and in rare cases sites can be inscribed on both lists simultaneously through an 'emergency' nomination procedure when a country's heritage is under severe active threat, such as conflict. This is squarely GS1 (World Geography, Important Physical Phenomena) and GS3 (Environment, Biodiversity) content, frequently tested through World Heritage Site facts.

Core Context

The Boma-Badingilo Migratory Landscape, spanning Boma National Park, Badingilo National Park and the wildlife corridors connecting them in South Sudan, was confirmed in 2026 as the country's first UNESCO World Heritage Site, inscribed through an emergency procedure and simultaneously placed on the List of World Heritage in Danger given the fragile security situation in the region.

Latest Developments

• The inscription was approved by the UNESCO World Heritage Committee at its 48th session, held in Busan, Republic of Korea, on 26 July 2026, and continued to be discussed and reported through early September 2026.
• The landscape covers approximately 12 million hectares of savannas, floodplains, wetlands and woodlands, making it one of the largest protected landscapes inscribed by UNESCO.
• It sustains one of the world's largest remaining terrestrial mammal migrations, involving an estimated six million White-eared Kob, Tiang and Mongalla Gazelle moving across the landscape in response to seasonal environmental change.
• UNESCO used an 'emergency' listing procedure, reserved for sites of outstanding value facing urgent existential threats, to inscribe the site.
• Simultaneous inscription on both the World Heritage List and the List of World Heritage in Danger is uncommon and signals both exceptional ecological value and acute conservation risk.

UPSC Prelims Pointers

• The UNESCO World Heritage Convention was adopted in 1972; World Heritage Sites are classified as Natural, Cultural, or Mixed.
• The List of World Heritage in Danger is a distinct sub-list for sites facing serious threats (conflict, poaching, development pressure, climate change, etc.).
• The White-eared Kob migration in South Sudan is considered one of the largest overland mammal migrations on Earth, comparable in scale to the Serengeti-Mara wildebeest migration in East Africa.
• India has 45 UNESCO World Heritage Sites as of 2026 (37 Cultural, 7 Natural, 1 Mixed), a useful comparative Prelims fact whenever such 'first World Heritage Site' news breaks for other countries.

7. Science News: ISRO's GSLV-F17 Launches EOS-05 into Geosynchronous Transfer Orbit

Basic Concept

The Geosynchronous Satellite Launch Vehicle (GSLV) is one of India's operational launch vehicle families, alongside the Polar Satellite Launch Vehicle (PSLV) and the Launch Vehicle Mark-3 (LVM3), developed indigenously after technology-denial regimes blocked the transfer of cryogenic engine technology to India in the 1990s, prompting the Indian Space Research Organisation (ISRO) to develop its own cryogenic upper stage. GSLV is primarily used to place heavier communication and Earth-observation satellites into Geosynchronous Transfer Orbit (GTO), from where satellites use onboard propulsion to reach their final operational orbit. This is core GS3 (Science and Technology - Space) content.

Core Context

On 4 September 2026, ISRO successfully launched GSLV-F17, its 19th GSLV flight, carrying EOS-05 — described as the heaviest satellite yet flown on a GSLV and India's first imaging satellite specifically designed for operation from a geosynchronous orbit — from the Satish Dhawan Space Centre in Sriharikota.

Latest Developments

• GSLV-F17 lifted off on 4 September 2026 from the Second Launch Pad at the Satish Dhawan Space Centre, Sriharikota, marking the 19th flight of the GSLV programme.
• EOS-05, at approximately 2,637 kg, is the heaviest satellite launched by a GSLV to date.
• The satellite was placed into a Sub-Geosynchronous Transfer Orbit (Sub-GTO) and will use its own onboard propulsion system to gradually raise its orbit to its intended operational position.
• EOS-05 is designed to support applications across agriculture, water resources, urban planning, forestry, ocean resources and environmental monitoring from a geosynchronous vantage point, enabling near-continuous observation of the Indian landmass.
• The mission continues ISRO's Earth Observation Satellite (EOS) series, which has progressively expanded India's indigenous remote-sensing and disaster-monitoring capability.

UPSC Prelims Pointers

• India developed its own cryogenic upper-stage technology indigenously after a technology-denial regime blocked its transfer from Russia in the 1990s.
• India's main operational launch vehicles are the PSLV, GSLV and LVM3 (formerly GSLV Mk III).
• Geosynchronous Transfer Orbit (GTO) is an elliptical orbit used as a transfer path to reach Geostationary Orbit (GEO), roughly 36,000 km above the equator.
• A geosynchronous imaging satellite, unlike a polar-orbiting one, can observe the same region of Earth almost continuously, which is valuable for disaster and weather monitoring.

9. Practice MCQs

Practice MCQs

Q1. Consider the following statements regarding the National Clean Air Programme (NCAP):
1. It was launched in 2019 by the Ministry of Environment, Forest and Climate Change.
2. Its original target was a 20-30% reduction in PM2.5/PM10 concentration by 2024, using 2017 as the base year.
3. It covers only those cities that are state capitals.
Which of the statements given above is/are correct?

• (a) 1 and 2 only
• (b) 2 and 3 only
• (c) 1 only
• (d) 1, 2 and 3

Answer: (a) 1 and 2 only

Explanation: NCAP was launched in January 2019 by MoEFCC with an initial 20-30% reduction target for 2024 (2017 base year), later revised to 40% by 2025-26. However, it covers 'non-attainment cities' identified for failing to meet NAAQS over five years, not merely state capitals, making statement 3 incorrect.

Q2. With reference to the Pacific 'Ring of Fire', which of the following statements is/are correct?
1. It accounts for about 75% of the world's active and dormant volcanoes.
2. It is formed primarily due to subduction of oceanic plates beneath continental plates.
3. Anak Krakatau, located in the Sunda Strait, lies within this belt.
Select the correct answer using the code given below:

• (a) 1 and 2 only
• (b) 2 and 3 only
• (c) 1 and 3 only
• (d) 1, 2 and 3

Answer: (d) 1, 2 and 3

Explanation: All three statements are correct. The Ring of Fire hosts about 75% of the world's volcanoes and around 90% of earthquakes, is formed by plate subduction, and Indonesia (including Anak Krakatau in the Sunda Strait) lies squarely within this seismically active belt.

Q3. The 'Correct the Map' resolution, adopted by the United Nations General Assembly in September 2026, primarily seeks to:

• (a) Redraw international political boundaries based on historical claims
• (b) Promote wider use of equal-area map projections that more accurately represent relative landmass sizes
• (c) Establish a new UN body to arbitrate territorial disputes
• (d) Mandate all UN member states to adopt the Mercator projection in official documents

Answer: (b) Promote wider use of equal-area map projections that more accurately represent relative landmass sizes

Explanation: The resolution addresses cartographic distortion, particularly the Mercator projection's shrinking of Africa's relative size, and explicitly excludes political boundaries or territorial disputes from its scope; it does not create any new UN body, nor does it mandate the Mercator projection, which is precisely the projection it seeks to move away from.

Q4. Consider the following statements regarding UNESCO World Heritage Sites:
1. The World Heritage Convention was adopted in 1972.
2. A site can be simultaneously inscribed on the World Heritage List and the List of World Heritage in Danger.
3. The 'emergency' nomination procedure is used only for sites located in landlocked countries.
Which of the statements given above is/are correct?

• (a) 1 and 2 only
• (b) 2 and 3 only
• (c) 1 only
• (d) 1, 2 and 3

Answer: (a) 1 and 2 only

Explanation: The World Heritage Convention was adopted in 1972, and sites like the Boma-Badingilo Migratory Landscape show that simultaneous inscription on both lists is indeed possible. The emergency procedure is used for sites facing urgent existential threats, such as conflict, regardless of whether the country is landlocked, making statement 3 incorrect.

Q5. In the context of India's satellite launch vehicles, which of the following statements is/are correct?
1. GSLV uses an indigenously developed cryogenic upper stage.
2. EOS-05 was placed into a Sub-Geosynchronous Transfer Orbit by GSLV-F17.
3. PSLV is India's primary launch vehicle for placing heavy communication satellites into Geosynchronous Transfer Orbit.
Select the correct answer using the code given below:

• (a) 1 and 2 only
• (b) 1 and 3 only
• (c) 2 and 3 only
• (d) 1, 2 and 3

Answer: (a) 1 and 2 only

Explanation: GSLV's cryogenic upper stage was developed indigenously by ISRO after technology-transfer denial in the 1990s, and EOS-05 was indeed placed in a Sub-GTO by GSLV-F17. However, it is GSLV, not PSLV, that is primarily used for heavier communication and GTO-bound satellites; PSLV is optimised for polar and sun-synchronous orbit missions.
