    What is the Green Credit Programme?

    Why in the News?

    The Green Credit Programme (GCP), launched by the Ministry of Environment, Forest and Climate Change in 2023, was questioned by the Ministry of Law and Justice regarding the legality of its business model.

    About the Green Credit Programme (GCP)

    • The GCP launched by the MoEFCC in 2023, is a government initiative aimed at encouraging voluntary participation in environmental activities.
    • It was launched officially in December 2023 by PM Narendra Modi and Sheikh Mohammed bin Zayed Al Nahyan at the UN climate conference in Dubai.
    • Participants, including individuals, companies, and industries, can earn green credits for actions such as tree plantation, water conservation, waste management, and others.
    • These credits can be traded on a domestic platform, helping participants meet sustainability targets or fulfill legal obligations.
    • It is managed by the Indian Council of Forestry Research and Education (ICFRE), an autonomous organization under the MoEFCC.
    • The program supports the Mission LiFE (Lifestyle for Sustainable Environment) and encourages a market-based approach to environmental action.

    Criticisms of the Program:

    • Forest Diversion Concerns: The GCP has been criticized for promoting forest diversion for industrial activities. Critics argue that trading compensatory afforestation credits could weaken forest protection efforts and lead to the loss of old-growth forests.
    • Impact on Ecologically Valuable Lands: Concerns have been raised about plantations on degraded lands and scrublands, which provide essential ecological services. Critics argue these areas should not be used for plantations with uncertain long-term benefits.
    • Plantation Survival Issues: There are concerns about the survival rate of trees planted under the GCP, with some questioning if these plantations can truly replicate the environmental value of mature forests.
    • Compensatory Afforestation Conflicts: The GCP’s exchange of plantation credits for compensatory afforestation is seen as a challenge to the Van Adhiniyam, 1980, which mandates non-forest land for afforestation rather than degraded forest land.

  • RBI Notifications

    RBI celebrates 90 years

    Why in the News?

    The first monetary policy of RBI Governor Sanjay Malhotra in 2025 marks 90 years since the Reserve Bank of India (RBI) announced its inaugural monetary policy in 1935.

    RBI’s First Monetary Policy in 1935

    • On July 3, 1935, RBI set the bank rate at 3.5%, reflecting the Imperial Bank’s rate.
    • The CRR was set at 5% of demand liabilities and 2% of time liabilities on July 5, 1935.

    Evolution of RBI’s Monetary Policy

    • Bank Rate in Early RBI History:
      • The bank rate was a key tool introduced by the RBI in 1935 to control credit and liquidity. On July 3, 1935, the RBI set the bank rate at 3.5%, mirroring the rate of its predecessor, the Imperial Bank of India.
      • The RBI Act (1934) mandated its use for buying or re-discounting commercial paper, and it played a crucial role in India’s interest rate structure.
    • Role of Cash Reserve Ratio (CRR):
      • The CRR, introduced by the RBI, required banks to maintain a percentage of their deposits as reserves.
      • Influenced by the Federal Reserve Act of the USA, the CRR helped stabilize the banking system, especially during failures.
      • The CRR was set at 5% for demand liabilities and 2% for time liabilities in 1935, with adjustments made over time.
    • Exchange Rate Management
      • In 1935, the RBI managed the exchange rate of the 1 Indian rupee at 1 shilling and 6 pence.
      • This caused friction between nationalists, who favoured a lower exchange rate to boost exports, and the British, who preferred a higher rate to facilitate cheaper imports.
    • Disputes Between Government and RBI
      • The RBI’s decision to reduce the bank rate in 1935 was opposed by the government, fearing rupee depreciation.
      • This led to a conflict, resulting in the resignation of Osborne Smith, the first RBI Governor.
      • The incident highlighted tensions between the RBI’s monetary autonomy and government priorities.

    About Reserve Bank of India (RBI)

    • The RBI is the central bank and monetary authority of India established on April 1, 1935, under the Reserve Bank of India Act, 1934.
    • Its idea was incepted from the recommendations of the Hilton Young Commission.
    • Sir Osborne Arkell Smith, an Australian, served as the inaugural Governor.
    • He was succeeded by Sir C D Deshmukh, the first Indian to hold the position.
    • It is a centralized institution for India to effectively regulate its monetary and credit policies.
    • RBI had its initial headquarters in Kolkata, later moving permanently to Mumbai in 1937.
    • Initially, the RBI operated as a privately owned entity until its full nationalization in 1949.

    Functions and Initiatives:

    • Monetary Authority: The RBI controls the supply of money in the economy to stabilize exchange rates, maintain a healthy balance of payment, and control inflation.
    • Issuer of Currency: Sole authority to issue currency and combat circulation of counterfeit notes.
    • Banker to the Government: Acts as a banker to both the Central and State governments, providing short-term credit and financial advisory services.
    • Lender of Last Resort: Provides emergency liquidity assistance to banks during crises.
    • Custodian of Foreign Exchange Reserves: Manages foreign exchange reserves and administers the Foreign Exchange Management Act, 1999 (FEMA).
    • Regulator and Supervisor of Payment and Settlement Systems: Oversees payment and settlement systems in the country, ensuring efficiency and security.
    • Credit Control and Developmental Role: Promotes credit availability to productive sectors and fosters financial infrastructure development.

    Dr. Ambedkar’s Role in the Establishment of RBI:

    • Dr. B.R. Ambedkar’s contributions were particularly notable during the Hilton Young Commission discussions in 1926, where he presented his recommendations based on his book “The Problem of the Rupee – Its Origin and Its Solution.”
    • These discussions laid the foundation for establishing the RBI on April 1, 1935.

    Majorana 1 Chip and the Pursuit of Quantum Computing

    Why in the News?

    In December 2024, Microsoft introduced its quantum computing chip, Majorana 1, designed to solve industrial-scale problems by utilizing the properties of Majorana particles for practical quantum computing.

    About Majorana 1 Chip and the Science Behind

    • Microsoft introduced its Majorana 1 quantum computing chip, designed to solve large-scale problems using quantum computing.
    • This chip is named after Majorana particles, which have unique properties in particle physics.
    • Majorana particles are special because they are their own anti-particles.
    • This means that when two Majorana particles meet, they destroy each other and release energy.
    • This property is different from most particles, like electrons, which have separate anti-particles (for example, the electron’s anti-particle is the positron).
    • Why Majorana Particles Matter for Quantum Computing?
      • This unique property could make Majorana particles useful in quantum computing.
      • They could help make quantum bits (qubits) more stable, which is important for improving quantum computers.
      • Using Majorana particles may also help in topological quantum computing, which makes qubits less affected by external disturbances, making them more reliable.

    Beta Decay and Neutrinoless Double Beta Decay (0vßß):

    • Beta decay happens when an unstable atomic nucleus releases energy. In this process, a neutron in the nucleus turns into a proton, and an electron and anti-neutrino are emitted. There are two types of beta decay:
    1. Beta-minus decay: A neutron becomes a proton, releasing an electron and an anti-neutrino.
    2. Beta-plus decay: A proton turns into a neutron, releasing a positron and a neutrino.
    • What is Neutrinoless Double Beta Decay (0vßß)? Neutrinoless double beta decay is a rare event where two electrons are emitted instead of the usual electron and anti-neutrino. This suggests that neutrinos and anti-neutrinos might be the same particle, known as Majorana particles.
      • If scientists observe this type of decay, it will prove that neutrinos are Majorana particles and help measure their mass.
      • This discovery would improve our understanding of particle physics.

    AMoRE Experiment:

    • The AMoRE experiment is being conducted in South Korea to detect this rare 0vßß decay.
    • The experiment uses molybdenum-100 (Mo-100), which is known to undergo double beta decay. The team is measuring the energy differences in electron emissions to detect the 0vßß decay.
    • While no evidence has been found yet, the experiment continues to improve its sensitivity by using 100 kg of Mo-100 for more accurate measurements.

    Scientific Significance:

    • The search for 0vßß and studying Majorana particles could help answer important questions about the mass of neutrinos and improve our understanding of particle physics.
    • Learning more about neutrinos is key to both advancing quantum computing and understanding particle physics.

    IISc’s Bacteria-Based Technique for Lunar Habitat Construction

    Why in the News?

    Researchers at the Indian Institute of Science (IISc.) have developed a bacteria-based technique to repair bricks used in lunar habitats, designed to withstand the harsh conditions of the moon’s environment.

    About the Bacterial Brick:

    • The bacterial brick is an innovative material designed for building durable, eco-friendly structures in lunar habitats.
    • It is created using lunar soil simulants combined with Sporosarcina pasteurii, a bacteria that binds soil particles together, forming a solid material suitable for construction on the moon.
    • How is it made?
      • The bacteria Sporosarcina pasteurii converts urea and calcium into calcium carbonate crystals, which bind soil particles together to create a brick-like substance.
      • The process is further enhanced with guar gum, which serves as a natural adhesive, making it a low-cost, eco-friendly alternative to energy-intensive cement-based manufacturing.
      • The researchers also explored sintering, where a mixture of soil simulants and polyvinyl alcohol is heated to high temperatures, creating stronger, more pressure-resistant bricks.

    Significance for Lunar Surface Conditions:

    • The moon’s surface experiences extreme temperature fluctuations, ranging from 121°C to -133°C, causing bricks to crack and become brittle.
    • A bacteria-based repair technique using Sporosarcina pasteurii helps address these cracks.
      • When mixed with lunar soil simulant and guar gum, the bacteria effectively adhere to cracks, improving durability and enabling the bricks to withstand temperatures from 100°C to 175°C.
    • This approach offers a sustainable solution by allowing on-site construction with local lunar materials, reducing the need for Earth-based materials.
      • It ensures long-term structural integrity for lunar habitats, contributing to the sustainability of space missions.
    [UPSC 2011] Microbial fuel cells are considered a source of sustainable energy. Why?

    1. They use living organisms as catalysts (often including bacteria) to generate electricity from certain substrates.

    2. They use a variety of inorganic materials as substrates.

    3. They can be installed in wastewater treatment plants to cleanse water and produce electricity.

    Mentor’s Comment:  The Arctic has been isolated for centuries, but climate change is melting ice, which leads to opening access to valuable resources like oil, gas, and rare earth metals. Melting ice is also creating new trade routes. Unlike Antarctica, the Arctic has no strong legal protections, leading to territorial claims and military activity, increasing global tensions.

    Today’s editorial discusses the geopolitical impact of climate change in the Arctic. This topic is relevant for GS Paper 2 (International Relations) and GS Paper 3 (Environment).

    What are the key factors driving increased geopolitical tensions in the Arctic?

    • Climate Change & Melting Ice: The Arctic ice cap is shrinking, making previously inaccessible natural resources and trade routes viable. Example: The opening of the Northeast Passage along Russia’s coast could significantly reduce shipping times between Asia and Europe.
    • Competition for Natural Resources: The region holds an estimated 13% of the world’s undiscovered oil and 30% of untapped natural gas, along with rare earth minerals. Example: Greenland has significant deposits of rare earth elements, attracting interest from China and the U.S.
    • Territorial Disputes & Overlapping Claims: Countries are extending their maritime boundaries under UNCLOS to claim more of the Arctic seabed. Example: Russia, Canada, and Denmark have overlapping claims to the Lomonosov Ridge, a key Arctic seabed area.
    • Military Posturing & Strategic Control: Nations are increasing their military presence to assert dominance and protect interests. Example: Russia has expanded its Arctic military bases and deployed nuclear-powered icebreakers, while NATO has increased Arctic exercises.
    • New Maritime Trade Routes & Geopolitical Rivalry: The melting ice is opening faster, alternative shipping lanes, bypassing traditional routes like the Suez Canal. Example: China is promoting the Polar Silk Road via the Northeast Passage, while Russia maintains strict control over Arctic navigation.

    Who are the primary stakeholders controlling different regions of the Arctic?

    • Arctic Coastal Nations (Arctic Council Members): Eight countries control Arctic land and territorial waters: Canada, Denmark (via Greenland), Finland, Iceland, Norway, Russia, Sweden, and the U.S. Example: Russia has the largest Arctic coastline and controls key ports, while Canada claims sovereignty over the Northwest Passage.
    • International Governance & UNCLOS: The UN Convention on the Law of the Sea (UNCLOS) regulates maritime claims, allowing nations to extend seabed claims if proven as a continental shelf extension. Example: Russia, Canada, and Denmark have all submitted overlapping claims to the Arctic seabed under UNCLOS.
    • Non-Arctic Global Powers & Observers: Non-Arctic nations like China, India, the UK, and the EU monitor Arctic developments due to strategic interests in trade routes and resources. Example: China declared itself a “Near-Arctic State” in 2018 and is investing in icebreaker ships to influence Arctic shipping lanes.

    Where do territorial disputes and conflicting claims arise among Arctic nations?

    • Competing Seabed Claims under UNCLOS: Arctic nations claim extended seabed areas beyond their Exclusive Economic Zones (EEZs) by proving geological extensions of their continental shelves. Example: Russia, Canada, and Denmark (via Greenland) have overlapping claims to the Lomonosov Ridge in the central Arctic Ocean.
    • Northwest Passage Dispute (Canada vs. U.S.): Canada considers the Northwest Passage part of its internal waters, granting it control over navigation. The U.S. and other nations claim it is an international strait, allowing free passage. Example: The U.S. has conducted “freedom of navigation” operations in the passage, challenging Canada’s sovereignty.
    • Svalbard Archipelago (Norway vs. Russia): Norway administers Svalbard under the Svalbard Treaty (1920), granting access to signatory nations for commercial activities. However, Russia argues for broader rights. Example: Russia continues to expand mining operations in Svalbard and has politically challenged Norway’s restrictions on military activity there.
    • Greenland Sovereignty & U.S. Interest (Denmark vs. U.S.): The U.S. has questioned Denmark’s sovereignty over Greenland and previously attempted to purchase the island due to its strategic location and rare earth minerals. Example: In 2019, then-U.S. President Donald Trump expressed interest in buying Greenland, leading to diplomatic tensions with Denmark.
    • Barents Sea & Arctic Borders (Norway vs. Russia): Russia and Norway have had disputes over their maritime boundary in the Barents Sea, an area rich in oil, gas, and fisheries. Example: A 2010 agreement settled much of the dispute, but tensions persist, especially with increasing Russian military activity near Norwegian waters.

    Why is the Arctic considered strategically important for global powers?

    • Rich Natural Resources: The Arctic is estimated to hold 13% of the world’s undiscovered oil and 30% of its untapped natural gas, along with rare earth elements, phosphates, and fisheries. Example: Russia has significantly invested in Yamal LNG projects, while Greenland has attracted interest from China and the U.S. for its rare earth deposits.
    • New Trade Routes Due to Melting Ice: The Northeast Passage (along Russia’s coast) and the Northwest Passage (through Canada) could drastically reduce global shipping distances, saving billions in transportation costs. Example: China’s “Polar Silk Road” seeks to use the Northeast Passage for trade, reducing travel time between East Asia and Europe by 40% compared to the Suez Canal route.
    • Military & Geopolitical Significance: The Arctic provides strategic military advantages, including submarine deployment zones, early warning radar systems, and missile defense capabilities. Example: Russia has established new Arctic military bases, the U.S. has expanded its Thule Air Base in Greenland, and NATO has increased military exercises in the region.

    How are nations like Russia, China, and NATO asserting their influence in the Arctic region?

    • Russia: Militarization and Territorial Claims: Russia has the largest Arctic military presence, including nuclear-powered icebreakers, air bases, and missile defense systems. It has also made territorial claims under UNCLOS to extend its control over the Arctic seabed. Example: In 2007, Russia planted its flag on the Arctic seabed at the North Pole and continues to expand its Arctic military bases, such as in Franz Josef Land and the Kola Peninsula.
    • China: Economic Investments and Strategic Partnerships: China, though not an Arctic nation, calls itself a “Near-Arctic State” and is expanding its influence through investments in Arctic infrastructure, scientific research, and trade routes (Polar Silk Road). Example: China has invested in Arctic mining projects in Greenland and collaborated with Russia on LNG projects, like the Yamal LNG plant. It is also building nuclear-powered icebreakers.
    • NATO: Strengthening Military Presence and Alliances: NATO has intensified military exercises and surveillance in the Arctic, especially after Finland and Sweden joined the alliance following Russia’s invasion of Ukraine. Example: In 2024, NATO conducted large-scale Arctic military drills near the Russian border in Finland and strengthened defense ties with Canada and Norway.

    Way forward: 

    • Strengthening Arctic Governance & Diplomacy: Enhance international cooperation through the Arctic Council and UNCLOS to manage territorial disputes, resource exploration, and environmental challenges. Example: Establish legally binding agreements for sustainable Arctic resource extraction and conflict resolution mechanisms to prevent geopolitical tensions.
    • Balancing Economic Development with Environmental Protection: Promote responsible Arctic development by enforcing strict environmental regulations while ensuring indigenous rights and sustainable economic activities. Example: Encourage renewable energy projects, scientific research, and eco-friendly shipping practices to mitigate the impact of Arctic exploitation.
