Prelims level: Greedflation, Wage-price spiral
Why in the News?
Political campaigns highlight inequality in India. Accusations suggest billionaires amass wealth through monopolistic control, dictating prices and suppressing real wages.
Monopoly Power and Economic Dynamics
Monopoly Influence: Billionaires often amass wealth through monopolistic control, enabling them to dictate prices and suppress real wages.
Consumption Conundrum: Higher mark-ups under monopolies lead to reduced real wages and diminished consumption power, hindering economic growth and investment.
Greedflation Impact: The phenomenon of “Greedflation,” where companies raise prices to bolster profit margins amidst multiple demand-and-supply shocks, exacerbates inflationary pressures, particularly observed in developed economies.
So what is Greedflation?
Definition: Greedflation, in essence, signifies that corporate greed is driving inflation, rather than the traditional wage-price spiral, leading to a profit-price spiral.
Corporate Exploitation: Companies exploit inflation by significantly raising prices, surpassing the need to cover increased costs, thereby maximizing profit margins and perpetuating inflation.
Profit-Price Spiral: Unlike the wage-price spiral, it involves companies exploiting inflation by excessively raising prices to maximize profit margins, triggering a cycle of inflation.
Illustrative Scenario
Crisis Dynamics: During crises such as natural disasters or pandemics, businesses often raise prices due to increased input costs.
Exploitative Practices: However, some businesses exploit the situation by engaging in excessive profit-making through significantly inflated price mark-ups.
Impact of Greedflation
Disproportionate Impact: Greedflation disproportionately affects low-income and middle-class individuals, diminishing their consumption and lowering living standards.
Wealth Disparities: While benefiting the wealthy by inflating asset values, it widens the wealth gap and exacerbates income inequality.

Prelims level: Gold Reserves of RBI
Why in the News?
The RBI has repatriated over 100 tonnes of gold from the UK to its domestic vaults, the largest transfer since at least 1991.
What are Gold Reserves?
A gold reserve is the gold held by a country’s central bank, acting as a backup for financial promises and a store of value.
India, like other nations, stores some of its gold reserves in foreign vaults to spread out risk and facilitate international trading.
India’s Gold Reserves:
As of the end of March 2024, the RBI held 822.10 tonnes of gold, with 408.31 tonnes stored domestically.
The share of gold in the total forex of India is around 7-8% as of 2023.
Where does the RBI store its gold?
India’s gold reserves are primarily stored in the Bank of England, which is known for its stringent security protocols.
The RBI also stores a portion of its gold reserves at the:
Bank for International Settlements (BIS) in Basel, Switzerland, and the
Federal Reserve Bank of New York in the United States.
During India’s foreign exchange crisis in 1990-91, the country pledged some of its gold reserves to the Bank of England to secure a $405 million loan, according to reports.
Even though the loan was paid back by November 1991, India decided to keep the gold in the UK for convenience.
Why does the RBI store its gold in foreign banks?
Convenience: Storing gold overseas makes it easier for India to trade, engage in swaps and earn returns.
Averting Risks: There are risks involved, especially during times of geopolitical tensions and war.
The recent freezing of Russian assets by Western nations has raised worries about the safety of assets kept abroad and the RBI decision to shift a portion of the gold reserve to India could be prompted by these concerns.
Stable Prices: Unlike fiat currencies, which can be subject to inflation or devaluation due to various economic factors, the value of gold tends to be relatively stable over time, which makes it an attractive asset for central banks to hold as a reserve.
Benefits Offered by Gold Reserves
Control domestic gold prices: With its big stash of gold, the RBI can help control local gold prices by using some of it in India. Last financial year, the RBI added about 27.47 tonnes of gold to the total reserve, bringing it to 794.63 tonnes.
Security buffer: The increased gold reserve works as a hedge against any financial crisis and to take measures to control inflation as well as currency devaluation.
Why is the recent move significant?
Efficiency and Confidence: Bringing gold back to India reduces storage fees and signals confidence in the stability of the Indian economy.
Logistical Efficiency: Moving gold to India saves on storage fees paid to foreign custodians, such as the Bank of England.
Diversified Storage: Repatriation ensures diversified storage, enhancing security and reducing dependency on foreign storage.
Has the RBI made similar purchases or transfers of gold in the past?
RBI started buying gold in 2018 and had previously bought 200 tonnes during the global financial crisis in 2009.
In the first quarter of 2024, the RBI bought 19 tonnes of gold, surpassing the 16 tonnes purchased throughout 2023.

Prelims level: Coal Gradation, Coal reserves in India, Imports etc
Why in the News?
A report by the Organized Crime and Corruption Reporting Project suggests Adani Group claimed ‘low grade’ coal imported from Indonesia to be ‘high quality’ coal.
They inflated its value and sold it to Tamil Nadu’s power generation company, TANGEDCO (Tamil Nadu Generation and Distribution Company).
Coal Gradation in India
These terms are relative and depend on the coal’s Gross Calorific Value (GCV denoted in kilo-calories per kg), which indicates its energy generation potential. Higher GCV denotes better quality coal.
High-Grade (GCV > 7,000 kcal/kg) to
Low-Grade (GCV 2,200-2,500 kcal/kg).
Overall there are 17 grades of coal according to the Coal Ministry‘s classification.
Characteristics of Indian Coal:
Historically, Indian coal is high in ash content and low in calorific value compared to imports.
Higher ash content leads to increased emissions of particulate matter and pollutants.
Clean Coal Technologies:
Coal Washing: On-site processes such as coal washing are employed to reduce ash and moisture content, thereby improving energy efficiency and reducing environmental impact.
Coal Gasification: Another approach is coal gasification, where coal is converted into syngas through an integrated gasification combined cycle (IGCC). This process enhances efficiency and reduces emissions compared to traditional coal-burning methods.
Coal Reserves in India
India boasts the fourth-largest coal reserves globally, totaling nearly 319.02 billion tonnes.
Geological Distribution: These reserves are primarily located in:
Older Gondwana Formations: in Peninsular India, about 250 million years old.
Younger Tertiary Formations: in the North-Eastern region, 15 to 60 million years old.
Gondwana coal constitutes 99% of India’s coal production.
The top 5 States in terms of total coal reserves in India are: Jharkhand > Odisha > Chhattisgarh > West Bengal > Madhya Pradesh.
Types of Coal found:
Anthracite: This highest-grade coal contains 80-95% carbon and is found in smaller quantities in regions of Jammu and Kashmir.
Bituminous: A medium-grade coal with 60 to 80% carbon content, it is abundant in Jharkhand, Odisha, West Bengal, Chhattisgarh, and Madhya Pradesh.
Lignite: The lowest-grade coal, with 40 to 55% carbon content, is found in regions of Rajasthan, Tamil Nadu, and Jammu & Kashmir.
Status of Coal in India
In the fiscal year 2023-24, India’s coal production peaked at 997 million tonnes, primarily sourced from state-owned Coal India Ltd and its subsidiaries. Coking coal accounted for 58 million tonnes.
During the first quarter of 2024, renewable energy constituted 71.5% of India’s unprecedented 13.6 GW power generation capacity addition, signalling a notable departure from reliance on coal.
Coal Import Trends:
Reduction in Share: The share of coal imports in India’s total coal consumption decreased to 21% from April 2023 to January 2024, down from 22.48% in the corresponding period of the previous year.
Blending and Power Plant Imports: While there was a significant reduction of 36.69% in coal imports for blending by thermal power plants, imports by coal-based power plants surged by 94.21% during the same period.
Reasons for Coal Imports:
Quality Constraints: The scarcity of good quality coking coal, essential for steelmaking, necessitates coal imports to meet industrial demands.
Rising Energy Demand: Coal remains a vital component of India’s energy mix, prompting the need for imports to fulfil growing energy requirements.
Infrastructure Challenges: Challenges such as geological constraints, land acquisition issues, and environmental regulations impede domestic coal production

Prelims level: Mangroves in India
Why in the News?
The International Union for Nature Conservation (IUCN) has listed mangroves in coastal regions spanning Tamil Nadu, Sri Lanka and Maldives as ‘critically endangered’ in its first global assessment of mangrove ecosystems.
Red List of Mangrove Ecosystems: Study by IUCN
Global assessment reveals a 50% risk of mangrove ecosystem collapse. Without further conservation, by 2050, 7,065 sq km more mangroves will be lost, and 23,672 sq km submerged.
If we let this happen, the world is at risk of losing:
1.8B tonnes of carbon stored, costing society $336B (based on the social cost of carbon). Protects 2.1M lives and $36B worth of property from coastal flooding..
Sea-level rise is the main threat affecting mangrove ecosystems.
25% of the global mangrove area is predicted to be submerged in the next 50 Years.
1/3 of the world’s mangrove ecosystem provinces will be severely affected by sea-level rise.
Tamil Nadu’s Efforts for Mangroves Conservation
The Tamil Nadu Forest Department has doubled mangrove cover from 23 sq km in 2001 to 45 sq km in 2021, as per the Indian State of Forest Report.
Mangrove restoration projects have been undertaken across Nagapattinam, Thiruvarur, Cuddalore, Pudukottai, Ramanathapuram, Thiruvallur, and Villupuram districts, with plans for an additional 15 sq km restoration under the Tamil Nadu Coastal Restoration Mission funded by the World Bank.
Tamil Nadu’s TN-SHORE initiative, launched in January 2024, aims to address environmental challenges along the coastline. With Rs 1,675 crore funding, including 70% from the World Bank, it focuses on blue carbon sequestration.
Back2Basics: Mangroves
Mangroves constitute a group of trees and shrubs inhabiting the coastal intertidal zone.
They are found globally in tropical and subtropical regions, typically between latitudes 25° N and 25° S.
Mangroves are predominantly located in tropical regions due to their intolerance to the extreme cold conditions prevalent in temperate zones.
Features of Mangroves:
Adaptation to waterlogged and anoxic soil: Mangroves possess unique characteristics allowing them to survive in waterlogged and oxygen-deficient environments.
Halophytes: Mangrove species have the ability to filter out up to 90% of the salt from seawater as it enters their roots, with some species also excreting salt through glands in their leaves.
Water retention capacity: Thick succulent leaves store fresh water, while a waxy coating on some species’ leaves minimizes evaporation.
Pneumatophores: Certain mangroves develop pencil-like roots that emerge from the ground to absorb oxygen from the air, aiding in coping with tidal flooding.
Prop roots: Many mangrove trees possess dense aerial roots descending from their trunks and branches, which stabilize and support them against waves and tides.
Lenticellated bark: Oxygen enters mangroves through lenticels, small breathing pores in the bark and roots, enabling them to adapt to low oxygen conditions.
Viviparity: Seed pods germinate while still on the tree, facilitating immediate root growth upon dropping.
Mangroves in India:
According to the India State of Forest Report 2021, mangrove cover in India comprises 0.15% of the country’s total geographical area.
West Bengal has the highest percentage of area under total mangrove cover among states and union territories, followed by Gujarat and the Andaman and Nicobar Islands.
The Sundarbans, characterized by the dominant mangrove species sundari (Heritiera fomes), is the largest continuous mangrove forest globally.
Various mangrove areas in India are protected within reserves and sanctuaries such as the Sundarbans Tiger Reserve, Bhitarkanika, Coringa, Nelapattu, Point Calimere Wildlife Sanctuaries, Pirotan National Park, among others.

Prelims level: Frequent Volcanic eruptions this year, Sundhnuksgigar and other Volcanoes Why in the News?
Why in the News?
Southwest Iceland witnessed the eruption of the Sundhnuksgigar volcano, triggering evacuations in the nearby areas.
About Sundhnuksgigar Volcano
Sundhnuksgigar is a row of craters just outside the town of Grindavik on the Reykjanes peninsula
It is situated on the Mid-Atlantic Ridge, a divergent boundary where the Eurasian and North American tectonic plates are moving apart.
What is a Volcano?
A volcano is a fissure or vent in the Earth’s crust through which gases, molten rock materials (lava), ash, steam, sulphur dioxide etc., are expelled during an eruption.
These openings occur where the rock layers in the Earth’s crust are relatively weak.
Volcanic activity is categorized as an endogenic process, originating from within the Earth.
Depending on the explosivity of the volcano, various extrusive and intrusive landforms can be formed.
Different types of volcanoes can be classified based on the frequency of eruption and the nature of the eruption:
1. Frequency of eruption:
Active volcanoes: Frequent eruptions in Pacific Ring of Fire: New Zealand, Southeast Asia, Japan, western Americas. Linked to plate tectonics, like Kilauea and Santa Maria. High seismicity, volcanic activity.
Dormant Volcanoes: These are not currently erupting but have the potential to erupt again in the future. An example is Mount Kilimanjaro in Tanzania, the highest mountain in Africa.
Extinct or inactive volcanoes: These have not erupted in the distant geological past. Dhinodhar Hill in Gujarat is an example.
2. Nature of Eruption:
Shield Volcanoes: Largest and least explosive volcanoes, formed from basalt lava. Often low in explosivity, except when water interacts. Hawaiian volcanoes exemplify this..
Composite Volcanoes: Volcanoes with cooler, thicker lava, built up through explosive eruptions. Layer ash, pyroclastic material, and lava flow. Examples: Mayon, Fuji, Rainier.
Calderas: The most explosive volcanoes, prone to collapsing inward during eruptions rather than building upwards. The resulting depressions are called calderas.
Flood Basalt Provinces: These volcanoes erupt highly fluid lava that travels long distances, covering vast areas with thick basalt flows.
Reasons for Iceland’s Volcanism
Tectonic Activity: Iceland is situated on the Mid-Atlantic Ridge, where the Eurasian and North American plates diverge. This creates volcanic rift zones where magma rises to the surface, leading to eruptions.
Hotspots: Additionally, Iceland is positioned over a hotspot, contributing to heightened volcanic activity. Hotspots are areas where magma from the mantle rises towards the surface, fueling eruptions.
Subglacial Volcanism: Iceland’s volcanic activity is not limited to the surface; some eruptions occur beneath glaciers, leading to explosive interactions between lava and ice. These subglacial eruptions can produce powerful steam explosions, ash clouds, and catastrophic floods known as jokulhlaup.

Prelims level: Koya Tribe
Mains level: Legal Challenges and Rights
Why in the news?
The Koya tribe in Andhra Pradesh is facing a cultural crisis due to stricter liquor regulations enforced by the Special Enforcement Bureau (SEB).
About Koya tribe
Koya are one of the few multi-racial and multi-lingual tribal communities in India.
They live in the forests, plains, and valleys on both sides of the Godavari River which lies in Andhra Pradesh. Many also live in the states of Madhya Pradesh and Orissa.
They believe their main deity still resides in a cave in the Bastar region.
Cultural Crisis (Disruption of Traditions):
Mahua liquor is brewed from the flowers of the Mahua tree which is integral to Koya cultural and religious ceremonies including naming ceremonies, weddings, and death anniversaries.
Police raids and seizures of Mahua liquor disrupt these traditions causing cultural shocks within the community. For example, recently the naming ceremony of Madakam Janakamma’s child was held without Mahua liquor due to SEB raids.
Tribal Rights (Legal Challenges and Rights):
The Andhra Pradesh Prohibition Act, 1995, does not exempt the Koya tribe from brewing and storing Mahua liquor, despite its cultural significance.
The Panchayat (Extension to Scheduled Areas) Act (PESA), 1996empowers the gram sabha to protect tribal traditions and culture but its implementation is questionable as SEB raids continue unabated.
Koya villagers are often coerced into paying bribes to avoid legal charges, highlighting the tension between law enforcement and tribal rights.
Impact on Collection(Economic Consequences):
Many Koya households have ceased Mahua flower collection due to fear of police raids, significantly affecting their primary source of income.
Destruction of freshly collected flowers during raids further disincentivizes collection, reducing the supply of Mahua flowers to weekly markets (shandies) where they are exchanged for essential goods.
Guardians of Culture (Preservation of Heritage):
The Koya tribe, especially those not displaced by the Polavaram irrigation project, are seen as custodians of their culture. However, displacement and integration with non-tribal communities threaten their cultural identity.
Local leaders and activists argue for the need to empower Koya women with training in producing value-added products from Mahua flowers, rather than undermining their traditional practices and economic activities.
Legal and Policy Measures
Amend the Andhra Pradesh Prohibition Act, 1995: Introduce exemptions or special provisions that recognize and protect the traditional brewing and usage of Mahua liquor for cultural and religious purposes by the Koya tribe.
Strengthen Implementation of PESA Act: Ensure that the Panchayat (Extension to Scheduled Areas) Act (PESA), 1996, is fully implemented. Empower Gram Sabhas to have a greater say in protecting tribal traditions, including the brewing of Mahua liquor.
Conclusion: The enforcement actions by the SEB, while aimed at regulating liquor, pose a significant threat to the Koya tribe’s cultural heritage and economic well-being. Balancing legal regulations with respect for tribal traditions and rights is crucial to preserving the Koya way of life.

Prelims level: Op Blue Star, Golden Temple, Khalistani Movement
Mains level: Separatists activism and threat to internal security
Why in the News?
June 1, the day Punjab votes in the last phase of the Lok Sabha election, happens to be the anniversary of “Operation Blue Star” which has influenced the recent history and politics of the state.
Operation Blue Star
Operation Blue Star was a military operation carried out by the Indian Army in June 1984 to remove Khalistani group-based militants who were hiding inside the Golden Temple complex in Amritsar, Punjab.
The militants, led by Jarnail Singh Bhindranwale, had fortified the temple complex and were advocating for an independent Sikh state called Khalistan.
The operation aimed toflush out the militants from the Golden Temple complex and restore law and order in the region.
However, it resulted in significant casualties and damage to the sacred shrine.
The operation began on June 1, 1984, and lasted for 10 days
The operation was highly controversial and led to widespread outrage among Sikhs, both in India and abroad. It also had political repercussions, including the assassination of Prime Minister Indira Gandhi by her bodyguards later that year, which sparked anti-Sikh riots across India.
What is the Khalistan movement?
The Khalistan movement is a Sikh separatist movement aiming to establish a sovereign state called Khalistan (Land of the Khalsa) in the Punjab region of India and Pakistan.
Factors Contributing to Khalistan’s Rise:
Partition of India (1947): The division of Punjab and the loss of Sikh holy sites in Pakistan led to a sense of displacement and marginalisation among Sikhs.
Linguistic Reorganization of States (1966): The creation of a Sikh-majority Punjab but with reduced territorial size and economic potential further fueled the desire for greater autonomy and cultural rights.
Anandpur Sahib Resolution (1973): The demand for greater autonomy and cultural rights for Punjab was seen as a secessionist threat by the central government, leading to increased tensions.
External Support: The involvement of external forces, such as Pakistan, which have supported and funded some Khalistani groups for their strategic interests, has also played a significant role in the movement’s persistence.
