Daily UPSC Current Affairs | Ramappa Temple: Heritage Versus a Proposed Coal Mine
Syllabus Mapping
GS Paper I: Indian Heritage and Culture (architecture, art forms of the medieval period)
GS Paper III: Environment, impact of mining on ecosystems and heritage
Prelims: Medieval temple architecture, UNESCO-inscribed sites, Telangana
Why in News?
Heritage activists, including the Kakatiya Heritage Trust, want the proposed PVNR opencast coal mine at Venkatapur (Mulugu district, Telangana) withdrawn. They fear it could slowly damage the UNESCO-inscribed Kakatiya Rudreshwara Temple, better known as the Ramappa Temple, and the Ramappa Lake next to it. Plans are on to bring people from 15 villages together and hold mass protests after Dasara. A delegation has already met Union Coal and Mines Minister G. Kishan Reddy and asked him to step in.
Core Facts & Background
The temple is an art-and-culture favourite, so the details below matter.
| Point | Detail |
|---|---|
| Built in | 1213 AD, under the Kakatiya Empire |
| Builder | Recherla Rudra, a general of King Ganapati Deva |
| Presiding deity | Ramalingeswara Swamy |
| Why “Ramappa”? | Named after the sculptor who worked on it for about 40 years |
| Platform | Six-feet-high, star-shaped |
| Foundation | Sandbox technique |
| Flooring and pillars | Granite flooring, basalt pillars |
| Superstructure | Red sandstone below; white gopuram of light bricks that reportedly float on water |
| Inscription | Dates it to 1135 Samvat-Saka (12 January 1214) |
Travellers from Europe were so taken by the temple that one called it the brightest star among the medieval temples of the Deccan. The Kakatiya style of gateways, the article adds, is found only in this region.
What is the sandbox technique? Builders dug a pit for the foundation and filled it with a mix of sand-lime, jaggery (as a binder) and karakkaya (black myrobalan fruit) before raising the structure on top. The sand layer works like a cushion during earthquakes, because most tremors lose strength while travelling through sand before they reach the actual foundation.
What worries the experts?
- Former NIT-Warangal professor M. Pandu Ranga Rao says the mine would sit about 5 km downstream of the lake and temple and go down roughly 300 metres.
- A Geological Survey of India report, he points out, suggests lake water could influence groundwater movement along geological lineaments and faults towards the mine.
- Since the temple stands on a sandbox foundation, interconnected lineaments under the lake and temple area could affect it through piping. The Kakatiya Heritage Trust says the temple already shows signs of distress.
- Singareni Collieries Company Ltd. is reportedly gearing up to proceed despite these concerns.
Pros & Cons
| Heritage Protection (Why activists push back) | Concerns / Open Questions |
|---|---|
| Protects a UNESCO-inscribed 800-year-old monument | Reports suggest SCCL is preparing to move ahead anyway |
| Safeguards Ramappa Lake and groundwater balance | Technical link between mine and temple is argued, not yet settled in public |
| Preserves a unique sandbox foundation that depends on stable ground | Temple already shows signs of distress |
| Keeps the site safe for tourism and local identity | Mass protest and a Centre-State standoff are likely |
Note: the article does not spell out the company’s own case for the mine, so we have not assumed one.
Way Forward
- Order an independent geological and structural study on groundwater, faults and the foundation before any clearance.
- Carry out a proper heritage impact assessment, with the Archaeological and heritage bodies in the loop.
- Involve the local villagers and the Heritage Trust in decisions.
- Keep a monitoring plan for cracks and signs of distress in the temple.
- If risk is confirmed, explore alternatives rather than risk an irreversible loss.
Daily UPSC Current Affairs | The ECI’s Constitutional Mandate Under Strain
Syllabus Mapping
GS Paper II: Constitutional bodies, Election Commission, Representation of the People Act, electoral reforms
Prelims: Articles 324, 326 and 329; Section 21 of RPA 1950
Why in News?
A former Secretary General of the Lok Sabha, P.D.T. Achary, has argued that the Election Commission’s Special Intensive Revision (SIR) of electoral rolls shows disregard for procedure and law. His main point is that the SIR has no clear footing in the statute, and that the Commission’s reputation is paying the price.
Core Facts & Background
Constitutional provisions at a glance
| Provision | What it says |
|---|---|
| Article 324 | Superintendence, direction and control of elections rest with the ECI |
| Article 326 | Elections to Lok Sabha and State Assemblies are based on adult suffrage |
| Article 329 | Bars courts from interfering in electoral matters, subject to constitutional provisions |
| Section 21, RPA 1950 | Preparation and revision of electoral rolls |
The legal argument in short
- Under Section 21(2), rolls are revised by reference to a qualifying date, before each general election, before a bye-election, and at any time the ECI directs. Rule 25 of the Registration of Electors Rules, 1960 allows the revision to be intensive, summary, or partly intensive and partly summary.
- Section 21(3) lets the ECI, for recorded reasons, order a special revision for a constituency or part of it. The writer stresses that this is meant for limited situations, not as a general tool.
- “Special Intensive Revision” appears nowhere in the law, according to the article. Article 324 gives wide powers, but not unlimited ones, and where Parliament has legislated the Commission must follow the law.
Four kinds of roll revision
| Type | How it works |
|---|---|
| Intensive | Fresh rolls from scratch with door-to-door verification |
| Summary | Annual update based on claims and objections, no field verification |
| Partly intensive and partly summary | Existing rolls published as draft while officers verify households |
| Special | Used when routine updates are judged inadequate; can be combined with other methods |
The SIR, being run in Bihar, is described as a method created by the ECI in 2025 to validate voter citizenship, and it is not defined in the electoral rules.
Other points raised: The writer cites media reports that 13 crore voters have been removed from rolls in SIR exercises, and says this runs against the spirit of Article 326. He also notes that the two Election Commissioners have said they were not kept in the loop. He recalls that in the Constituent Assembly, Dr. B.R. Ambedkar wanted the ECI kept free from executive control, and he suggests a two-thirds parliamentary approval for appointing the Chief Election Commissioner.
Pros & Cons
| Arguments for Cleaning Rolls | Concerns Raised |
|---|---|
| Accurate rolls are the base of free and fair elections | Wrongful exclusion of genuine voters |
| A special exercise can be justified when routine updates fall short | Unclear legal basis and procedure for the SIR |
| Citizenship validation protects electoral integrity | Weak consultation within the Commission and with stakeholders |
| Article 324 gives the ECI broad authority | Independence must not become absence of accountability |
Way Forward
- Follow due process before any name is deleted, with clear and public criteria.
- Give affected voters a real chance to challenge and appeal.
- Make sure every decision rests on a clear legal provision.
- Strengthen consultation among Election Commissioners and with political parties.
- Balance clean rolls with universal adult suffrage, so integrity and inclusion move together.
Daily UPSC Current Affairs | Evolving US Defence Strategy: What It Means for India
Syllabus Mapping
GS Paper II: India and its neighbourhood, bilateral and global groupings, effect of policies of developed countries on India
Mains Focus: India-US relations, Indo-Pacific, strategic autonomy
Why in News?
Elbridge A. Colby, the US Under Secretary of War for Policy, released a mid-term assessment of the Trump administration’s defence strategy, a month before the US mid-term elections. The update to the 2026 National Defence Strategy shows how Washington is turning priorities into policy, and an analysis in The Hindu explains the consequences for India.
Core Facts & Background
The four main goals:
- Defend the US homeland.
- Deter China.
- Win more support from allies and partners.
- Rebuild the US defence industry.
The new bargain with partners: For years, the US supplied most of the military muscle behind its alliances. The new approach expects partners to carry more weight in their own regions.
| Region | What the US expects |
|---|---|
| Europe | Lead on its own defence and take more responsibility for security, including on Russia |
| Korean Peninsula | South Korea to do more |
| Indo-Pacific | Japan and Australia to play a bigger role |
| China focus | Deterrence, especially along the First Island Chain, while trade talks with Beijing continue |
So Washington competes with China on military matters and negotiates with it on trade at the same time.
Where India fits: India’s value to the US rests mainly on China and the Indo-Pacific. Interests overlap but will not always match. India’s ties with Russia, its energy needs and its wish for strategic autonomy are the awkward parts. The article says the real change is in what is expected: India should help keep the regional balance, work more closely on defence, join technology and supply-chain projects, and build up its own military strength. India is already deepening partnerships with France, Europe, Japan, Australia and the Gulf, while holding on to its ties with Russia.
Pros & Cons
| Opportunities for India | Risks and Challenges |
|---|---|
| A stronger India becomes more valuable to Washington | Expectations to “do more” may outrun India’s capacity |
| More defence, technology and supply-chain cooperation | US and Indian interests will not always align |
| Greater bargaining power as India’s capability grows | Ties with Russia and the pursuit of autonomy can create friction |
| Wider partnerships beyond the US | Leverage takes time to build, as China’s example shows |
Way Forward
- Build capability and keep the freedom to use it.
- Work closely with Washington, but grow India’s own defence industry, technology sector and partnerships.
- Treat leverage as the goal: economic scale, military strength, technology and market access.
- Judge the next phase of India-US ties less by the “strategic partner” label and more by what two increasingly capable powers can do together.
Daily UPSC Current Affairs | US Exit from Iraq
Syllabus Mapping
GS Paper II: Effect of policies and politics of developed countries on India’s interests; West Asia
Mains Focus: Regime-change wars, militias, regional balance
Why in News?
On 30 September 2026, more than 23 years after invading, US troops finally left Iraq. They did so in the middle of another American war in the region, and The Hindu’s editorial describes the departure as one made in weariness, if not defeat.
Core Facts & Background
A short timeline
| Year | Event |
|---|---|
| March 2003 | US invades Iraq, citing weapons of mass destruction and terror links |
| 2011 | President Obama announces withdrawal |
| 2011 onwards | Troops return when the Islamic State seizes large areas of Iraq and Syria |
| By 2014 | Al-Qaeda in Iraq transforms into the Islamic State |
| 30 Sept 2026 | US troops leave Iraq |
What went wrong
- The weapons claim turned out to be false, while al-Qaeda built one of its most violent branches in post-war Iraq.
- Breaking up Saddam’s Ba’athist state and the sudden rise of Shia parties widened social divisions and led to a civil war that killed hundreds of thousands.
- The Popular Mobilisation Forces (Hashad al-Shabi), an umbrella of Iran-backed Shia militias, are now described as a state within the state.
- Saddam’s Iraq, though hostile to the Gulf monarchies, was a buffer between them and Iran. Once it fell, Iran extended its influence through Shia parties and militias.
Why leave now? When the US and Israel began bombing Iran on 28 February, the Hashad joined the war. The article says Iran and its allies have since carried out at least 600 attacks on US military and diplomatic facilities in Iraq, making a continued presence unsustainable.
The Afghanistan comparison: The US left Afghanistan after 20 years in the hands of the same Taliban it had removed in 2001. In Iraq, it leaves a war-ravaged country with a weak government and strong militias backed by a resurgent Iran.
Pros & Cons
| What the Exit Can Mean | Worries |
|---|---|
| An end to a long, costly military presence | Weak Iraqi government facing powerful militias |
| A chance for Iraq to chart its own course | Greater Iranian influence |
| Fewer US targets in Iraq during the Iran conflict | Possible revival of extremist groups, given history |
| Shows the limits of regime-change wars | Instability in West Asia affecting wider regions |
Way Forward
- Strengthen Iraq’s own institutions so the state, not militias, holds the monopoly on force.
- Keep regional dialogue open to prevent further escalation.
- For India, watch the effect on West Asian stability, since the region matters for its interests.
- Learn the wider lesson that military intervention without a political plan leaves long-term damage.
Daily UPSC Current Affairs | Does a Visa Guarantee Entry into India?
Syllabus Mapping
GS Paper II: Fundamental Rights, judiciary, statutes and their interpretation
Prelims: Articles 14, 19(1)(e), 21, 226; Immigration and Foreigners Act, 2025
Why in News?
The Delhi High Court has held that a valid visa does not give a foreigner an inherent or legally enforceable right to enter India. Justice Amit Mahajan dismissed, on 30 September, the petition of a Turkmenistan citizen who was stopped at Delhi airport despite holding a valid business visa.
Core Facts & Background
The case
- The petitioner arrived on 25 March on the same flight as her husband. He was allowed in; she was sent back to Turkmenistan the same day.
- She argued that no reasons were given and that letting her husband in but not her was discrimination under Articles 14 and 21.
- The Centre said a visa and permission to enter are two separate things, and that “adverse inputs” about her had been received. The court looked at material placed before it in a sealed cover.
- The material pointed to discrepancies in her personal details, no business card or invitation letter, thin details about her company, and her travel history.
What the court held
- There is no inherent or legally enforceable right of a foreigner to seek entry into India.
- The husband was not shown to be similarly placed, so the Article 14 argument failed.
- With no legally enforceable right infringed, there was no basis for a writ under Article 226.
The law behind it
- Under the Immigration and Foreigners Act, 2025, a foreigner needs a valid passport or travel document and a valid visa to enter.
- The Act (like the repealed Foreigners Act, 1946) allows the Centre to prohibit, regulate or restrict entry, and the Immigration Officer can ask for further information at the point of entry.
- The court leaned on two Supreme Court rulings: Hans Muller of Nuremburg v. Superintendent, Presidency Jail (1955) on the Centre’s wide discretion over foreigners, and Louis De Raedt v. Union of India (1991), which confined foreigners’ fundamental rights to Article 21. The right to reside and settle in India under Article 19(1)(e) belongs only to citizens.
Quick revision
| Article | Available to foreigners? |
|---|---|
| Article 14 | Yes |
| Article 19 | No, citizens only |
| Article 21 | Yes |
Pros & Cons
| Arguments Supporting the Ruling | Concerns |
|---|---|
| Entry control is a sovereign function tied to security and foreign policy | Reasons for denial may stay undisclosed (sealed cover) |
| Visa is a requirement, not a guarantee | Risk of arbitrary treatment of genuine travellers |
| Immigration Officers need discretion at the border | Limited chances for the traveller to challenge the decision |
Way Forward
- Keep discretion for security, but give travellers a clear written reason where national interest allows.
- Build transparent guidelines for the Immigration Officer’s checks.
- Ensure Article 21 protections, such as humane treatment, remain intact for those refused entry.
Daily UPSC Current Affairs | Mismatch in Data on Rabies Deaths
Syllabus Mapping
GS Paper II: Health, issues related to governance and transparency
GS Paper III: Science and Technology, disease surveillance
Prelims: ICMR-NIE, IDSP-IHIP, MCCD
Why in News?
India’s official figures for rabies deaths are far lower than what a major study estimates. The Health Ministry’s surveillance programme reported 50 deaths in 2023, the Registrar-General recorded 271 for the same year, while an ICMR study says about 5,726 people die of rabies every year.
Core Facts & Background
| Source | What it counts | Figure |
|---|---|---|
| IDSP-IHIP (Health Ministry disease surveillance) | Reported cases | 21 (2022), 50 (2023), 54 (2024) |
| MCCD (Registrar-General) | Medically certified deaths only | 66 (2022), 271 (2023) |
| ICMR-NIE study in The Lancet Infectious Diseases | Modelled annual estimate | 5,726 per year |
- The study surveyed 337,808 people in 78,807 households across 60 districts in 15 states, and estimated about 9.1 million animal bites each year, including roughly 5.6 million dog bites.
- The 5,726 figure comes from a community survey, lab data and a probability decision-tree model. It is an estimate, not a count of recorded deaths.
- The MCCD system covered only 22.3% of registered deaths in 2022 and 22.0% in 2023, and neither system gives a full national count.
- The 54 deaths on the 2024 surveillance record are less than 1% of the study’s estimate. A senior Health Ministry official said the numbers come from different methods and should not be treated as equivalent.
- For comparison, the Union Health Ministry reported 55 malaria, 131 dengue and 27 kala-azar deaths in 2025, but there is no comparable national measure for rabies.
- Globally, rabies causes around 59,000 deaths a year, and WHO estimates India accounts for 35% of them.
- India aims to eliminate dog-mediated human rabies by 2030.
Pros & Cons
| Positives | Challenges |
|---|---|
| A clear 2030 elimination target | No single, comparable national death count |
| A large, well-designed study now gives a realistic estimate | Deaths often happen in areas where they are not measured |
| Awareness of the data gap can improve surveillance | Gaps in surveillance outside the formal health system |
Way Forward
- Create one consolidated national system that captures rabies deaths, including those outside hospitals.
- Strengthen community-level reporting and link it to civil registration.
- Use the study’s estimate to plan vaccines, post-bite treatment and awareness.
- Track progress against the 2030 goal using consistent, comparable data.

Standout stories
- Women’s hockey: Beat China 1–0 for the first Asian Games gold since 1982, a 44-year wait, and qualified for LA 2028. The men beat Malaysia 5–1, defended their title and also qualified.
- Neeru Dhanda (shooting): Won individual trap gold, ending a 48-year wait (the previous one was Randhir Singh’s in 1978), plus mixed trap gold with Kynan Chenai, a new Asian record, and a team silver. She carried the flag at the closing ceremony.
- Kumkum Mohod (archery): First Indian woman to win individual recurve gold. The women’s recurve team also won its first-ever gold, ending South Korea’s 28-year run.
- Pranavi Urs: First Indian woman to win an individual golf gold.
- Vithya Ramraj (athletics): Broke P.T. Usha’s 42-year-old 400m hurdles national record with 54.75 seconds for bronze, won gold in the women’s 4×400m relay and silver in the mixed 4×400m relay.

- First-ever medals: MMA (Suchika Tariyal), soft tennis (Jay Meena), men’s double sculls (Satnam Singh and Salman Khan), women’s skeet team, and mixed skeet (Anantjeet Singh Naruka and Parinaaz Dhaliwal).
Ceremonies
- Opening ceremony at Mizuho Park Athletic Stadium, Nagoya, declared open by Emperor Naruhito, with 45 NOCs, 43 sports, 71 disciplines and 469 medal events. Flag-bearers: Manu Bhaker and Pawan Sehrawat (who replaced Tajinderpal Singh Toor at the last moment).
- Closing theme: “One Asia”. OCA President Sheikh Joaan bin Hamad Al Thani declared the Games closed. The flag and torch passed to Qatar, and the OCA may consider moving the Doha Games from 2030 to 2031 so they can serve as an Olympic qualifier before Brisbane 2032.
Pros & Cons
| Strengths | Areas to Improve |
|---|---|
| Wide medal base across many sports | Total fell short of the 106 record |
| Golden doubles in cricket, kabaddi and hockey | Only one badminton medal; defending doubles champions went out early |
| Many historic “firsts” in new sports | Several events narrowly lost (27 silvers) |
| Strong shooting, archery, boxing and wrestling | Consistency remains a challenge, and some traditionally strong sports were weaker |
Way Forward
- Back the new, rising sports (MMA, soft tennis, rowing, skeet) with long-term support.
- Work on consistency in sports where India usually wins.
- Convert silver finishes into gold through better coaching and sports science.
- Use the strong LA 2028 qualification base, especially in hockey, to plan Olympic preparation.
Daily UPSC Current Affairs | Letting the Wind Flow: Rising Skylines and Hot Cities
Syllabus Mapping
GS Paper III: Environment, urbanisation and its problems, climate and heat stress, disaster preparedness
GS Paper I: Urbanisation, its problems and remedies
Why in News?
A Hindu report on Indian cities explains why taller, denser buildings are making hot, humid days feel harsher: they interfere with natural winds, which are the quiet cooling system of a city.
Core Facts & Background
Key terms
| Term | Meaning |
|---|---|
| Terrestrial stilling | Gradual fall in wind speed near the ground worldwide since the 1980s |
| Venturi effect | Wind squeezed through narrow gaps between tall buildings speeds up and turns into a gust at street level |
| Downdraught effect | Wind hits a high-rise and is pushed downward along the building |
| Wind corridor | A path that lets breezes move through a city |
| Urban heat island | A city staying warmer than its surroundings, made worse by concrete, asphalt and less vegetation |
How buildings change the wind
- Cities packed with compound walls, podiums and clumps of high-rises of different heights slow the wind and block earlier wind corridors.
- Surface friction and turbulence increase, so wind near the ground (around 10 metres, where people walk) weakens.
- Loss of vegetation and more concrete cut evaporation and plant moisture release, which strengthens the urban heat island.
- Slower winds also disperse air pollution less effectively. Faster winds replace damp air near the ground with drier air, helping the body cool.
Where are we on solutions?
- Experts say there are no specific studies in India linking building shapes to wind speed, and weather instruments are placed inconsistently.
- Computational fluid dynamics (computer simulation of airflow) can model this, but it is expensive and needs strong expertise.
- Examples of city-wide ventilation planning exist in Stuttgart, Seoul and Hong Kong. Experts suggest cities like Chennai and Mumbai can do the same, possibly using satellite images to build city ventilation maps.
Pros & Cons
| Benefits of Dense, High-rise Cities | Costs to Wind and Comfort |
|---|---|
| Housing for growing populations in less land | Reduced breeze and higher heat stress |
| Efficient use of urban space | Gusts and downdraughts at street level |
| Opportunity to plan ventilation into design | Poorer pollution dispersal |
| Wind data and simulation capacity are still limited |
Way Forward
- Build wind and ventilation considerations into master plans and building rules.
- Protect and recreate wind corridors, lakes, water bodies and green cover.
- Standardise where anemometers are placed and collect proper wind data.
- Use simulation and satellite mapping to create city ventilation maps.
- Study how building shapes and heights can reduce turbulence without blocking airflow.
Daily UPSC Current Affairs | TAPAS-1: India’s First Private Thermal-Imaging Payload
Syllabus Mapping
GS Paper III: Science and Technology, space technology and its applications, role of the private sector
Prelims: Satellite types, CubeSats, remote sensing
Why in News?
TAPAS-1, India’s first dedicated commercial CubeSat-category thermal payload, was successfully placed in orbit by SpaceX’s Falcon 9. It was developed by the Ahmedabad-based start-up Satleo Labs, and for the next three years its data will be analysed with AI to produce insights for various sectors.
Core Facts & Background
| Feature | Detail |
|---|---|
| Full form | Thermal Access Platform for Analytics & Solutions |
| Developer | Satleo Labs, Ahmedabad |
| Purpose | Capture changes in heat from Earth’s surface as images |
| Technology | Long-wave infrared (LWIR) sensing, which records temperature information that ordinary optical images miss |
| Orbit | About 500 km high |
| Category | CubeSat, typically 10 cm × 10 cm × 10 cm |
| Weight | 1.5 kg |
| Launch vehicle | SpaceX Falcon 9 |
Uses
- Agriculture: Monitoring crop and water stress.

- Urban planning: Tracking temperature differences across a city in real time so municipalities can plan for heat stress.
Pros & Cons
| Advantages | Limitations |
|---|---|
| Opens the commercial thermal-imaging space to private Indian firms | Very small and light (1.5 kg), so capacity is limited |
| Reveals heat patterns invisible to normal cameras | Launched on a foreign rocket |
| Useful for farming, disasters and cities | Value depends on how well the data is analysed and used |
Way Forward
- Support start-ups through easier access to launch, testing and funding.
- Link thermal data with agriculture, disaster and urban agencies so it reaches decision-makers.
- Build reliable AI analysis that turns images into practical alerts and plans.
- Expand to more satellites for better coverage.
Daily UPSC Current Affairs | FAQs
Q1. Why is the Ramappa Temple in the news?
Activists fear that the proposed PVNR opencast coal mine at Venkatapur in Mulugu district could damage the temple and Ramappa Lake, and they have planned protests after Dasara.
Q2. Who built the Ramappa Temple, and when?
It was built in 1213 AD during the Kakatiya Empire by Recherla Rudra, a general of King Ganapati Deva.
Q3. What is the sandbox technique?
It is an old foundation method in which a pit is filled with sand-lime, jaggery and karakkaya fruit. The sand acts as a cushion that weakens earthquake vibrations.
Q4. What is the difference between an intensive and a summary revision of electoral rolls?
An intensive revision prepares fresh rolls with door-to-door verification, while a summary revision updates the existing roll through claims and objections without field verification.
Q5. Does a valid visa guarantee entry into India?
No. The Delhi High Court held that a visa does not give a legally enforceable right to enter India, and entry remains subject to immigration law and the powers of competent authorities.
Q6. Which Articles apply to foreigners in India?
Articles 14 and 21 are available to citizens and non-citizens alike. Article 19, including the right to reside and settle under 19(1)(e), is for citizens only.
Q7. Why do India’s rabies death numbers differ so much?
The sources use different methods. Surveillance reports only recorded cases, the Registrar-General’s system counts only medically certified deaths, and the ICMR study is a modelled estimate of about 5,726 deaths a year.
Q8. What was India’s final position at the Asian Games 2026?
India finished fourth with 85 medals: 21 gold, 27 silver and 37 bronze.
