{GS1 – Geo – HG – Community} Hatti Community

  • Context (TH): The Hatti community in HP will organise a protest to press their demand for implementing a law giving the Scheduled Tribe (ST) status to the community.
  • The Constitution (Scheduled Tribes) Order (Second Amendment) Act, 2023, granted ST status to the Hattis of the Trans-Giri region of HP’s Sirmaur district.
  • The Hattis is a close-knit community that resides in HP and Uttarakhand in the basin of the Giri and Tons Rivers (both tributaries of the Yamuna River).
  • They got their name from their traditional occupation of selling home-grown crops, vegetables, meat, and wool at small-town markets known as ‘haats’.
  • Hatti men traditionally don a distinctive white headgear on ceremonial occasions.
  • The two Hatti clans, Trans-Giri (HP) and Jaunsar Bawar (Uttarakhand) have similar traditions and common inter-marriages.
  • A rigid caste system is followed, and inter-caste marriages are traditionally discouraged.
  • The Hattis are governed by a traditional council called ‘Khumbli’, like the ‘Khaps’ of Haryana.
  • Polyandry is a common practice among the hatti community.
  • Tons River marks the border between the HP and Uttarakhand.

{GS1 – Geo – PG – Geomorphology} Almora Fault

  • Context (DTE | PIB): Data indicates increased earthquake activity in 2023.
  • It was mainly attributed to the activation of the Almora fault in Western Nepal.
  • This activation triggered significant mainshock earthquakes.
  • These mainshocks, accompanied by subsequent aftershocks, have led to an increased frequency of earthquakes in 2023.

Fault and Earthquake

  • A fault is a fracture in the Earth’s crust where two blocks of rock move relative to each other.
  • If the movement occurs, rock blocks rapidly release energy, which causes earthquakes.

Reasons for Fault Activation

  • The reasons for fault activation can be:
    • Natural factors: Plate tectonics, volcanic activity, landslides, change in water levels, fault geometry, local geology.
    • Anthropogenic factors: Mining, fluid injection, reservoir impoundment.
  • Plate tectonics: The movement of tectonic plates is the primary driver of fault activation.


  • It refers to the largest earthquake in a sequence of earthquakes.
  • It is often preceded by smaller earthquakes called foreshocks and followed by numerous smaller quakes called aftershocks.


  • A subsequent seismic event can be called an aftershock when:
    1. It is smaller in magnitude than the mainshock earthquake.
    2. It occurs in the same fault zone as the mainshock earthquake.
  • A subsequent seismic event cannot be called an aftershock when:
    1. It occurs in a different tectonic plate than the mainshock earthquake.
    2. It is larger in magnitude than the mainshock earthquake.
    3. It occurs in a different fault zone than the mainshock earthquake.
  • Aftershocks can occur in a few minutes to years after the mainshock.
  • There is no specific time limit for aftershocks, as their timing varies depending on the magnitude of the mainshock earthquake, the geology of the region, and the specific fault.





Magnitude Both are smaller than the mainshock earthquake
Location Both occur within the fault zone


Timing After the mainshock earthquake Before the mainshock earthquake
Duration Last for days, weeks, months, or even years Typically, it lasts for a few hours or days
Frequency More common than foreshocks Less common than aftershocks
Causation A direct response to the stress release caused by the mainshock An early indication of the stress buildup that ultimately leads to the mainshock

{GS2 – IR – US-China} Navigating the US-China Relationship

  • Context (TH): The U.S. President and his Chinese counterpart held a summit on the sidelines of the Asia-Pacific Economic Cooperation (APEC) conference.

Outcomes of the summit

Military to Military communication

  • The countries (nuclear weapons states) agreed to
    • Restore military-to-military communications — critical to prevent potential miscalculations.
    • Resume regular exchange of information under the Military Maritime Consultative Agreement that started in 1998.
  • These channels were closed after Nancy Pelosi’s (then Speaker of the U.S. House of Representatives) controversial visit to Taiwan in August 2022.

Trade deal

  • The Chinese agreed to buy substantial agricultural, energy, industrial and other products from the U.S. to reduce the US’s trade deficit with China.

{GS2 – S&T – Tech} Small Modular Reactors

  • Context (PIB | LM | TH | IE): GoI is advancing its efforts in clean energy transition by focusing on new technologies such as Small Nuclear Reactors (SMRs)
  • SMRs are promoted to help India’s broad strategy of decarbonisation.
  • SMRs are smaller, simpler, and more affordable than traditional nuclear reactors.
  • They typically have a power capacity of up to 300 MW(e), which is about 1/3rd of the generating capacity of traditional nuclear power reactors.
  • Harness nuclear fission to generate heat to produce energy.
  • They can start from a completely de-energized state without receiving energy from the grid.
    Reactor Capacity
    Large, conventional reactor 700+ MW(e)
    Small modular reactor 300 MW(e)
    Microreactor Up to ̴ 10 MW(e)
  • India has set its target to reach net-zero emissions by 2070.

Advantages of SMRs

  • Realising the goal of ‘Power for All’ as they can be installed into an existing grid and in areas lacking sufficient lines of transmission and grid capacity.
  • Contribute to grid stability and reliability by providing a stable baseload power supply that complements intermittent renewable energy sources.
  • Climate change mitigation: They have a smaller environmental footprint due to their compact size and reduced water consumption.
  • Environment Friendly: As per Nuclear Energy Institute, it consumes 30-60% less water per megawatt-hour compared to traditional nuclear plants.
  • Fuel efficient: Power plants based on SMRs may require less frequent refuelling, every 3 to 7 years, in comparison to between 1 and 2 years for conventional plants.
  • Greater deployment flexibility due to smaller, modular units allowing SMRs to be scaled up or down.
  • Land use efficiency: SMRs can repurpose retiring coal-based thermal power station sites.

Concerns with SMRs

  • Costly: SMRs will not be cost competitive due to the need to build thousands of such high priced reactors to achieve factory-based cost reductions → higher cost per unit of electricity generated.
  • Security risk: “nuclear backpacks” highlights concerns about the security risks associated with the portability and small size of SMRs.
  • Nuclear waste: According to a study, SMRs produce radioactive waste up by 30 percent compared to conventional reactors.
  • Other challenges: Limited fuel options, lack of proven experience as they are still in early stages of development, uncertainty about reliability, environmental impact.

Way Ahead

  • The Atomic Energy Act must be amended to allow the private sector to set up SMRs.
  • To ensure safety, security, and safeguards, control of nuclear fuel and radioactive waste must remain with the GoI.
  • GoI must enact a law to establish an independent, empowered regulatory board.
  • GoI can negotiate with foreign suppliers to reprocess nuclear waste from all SMRs in a state-controlled facility under IAEA safeguards.
  • The Department of Atomic Energy must improve the public perception of nuclear power in India.
  • Schemes like the Production Linked Incentive (PLI) scheme for SMRs can be introduced.

India-US ‘123 Agreement’ (or US-India Civil Nuclear Agreement)

  • It was signed in 2008 for peaceful nuclear cooperation between the two countries.
  • It allows India to develop a strategic reserve of nuclear fuel to guard against supply disruptions.
  • It also allows India to reprocess spent fuel from SMRs under IAEA safeguards.

International Atomic Energy Agency (IAEA)

  • IAEA is an autonomous international organisation within the United Nations system.
  • It seeks to maximise the contribution of nuclear technology to society while verifying its peaceful use.
  • Established in 1957, it has 175 Member States; India has been a member since its inception.
  • It is headquartered in Vienna, Austria.

Department of Atomic Energy (DEA)

  • DAE was set up under the direct charge of the Prime Minister through a Presidential Order in 1954.
  • It transacts all GoI businesses related to atomic energy and functions under the Atomic Energy Act.

Atomic Energy Commission (AEC)

  • AEC was first set up in 1948 in the Department of Scientific Research.
  • Subsequently, a GoI Resolution established AEC in the Department of Atomic Energy in 1958.
  • It is responsible for formulating the Department of Atomic Energy policy.

Present Status of Small Modular Reactors

  • Two operational SMRs exist globally:
    1. Akademik Lomonosov Plant, Russia (the world’s floating nuclear power station)
    2. China
  • Two more SMRs are under construction in Argentina and Russia.

{GS2 – Social Sector – Health – Disease} Pompe Disease

  • Context (IE): India’s first Pompe disease patient passes away.
  • Also known as Glycogen Storage Disease Type II, it is a rare genetic disorder.
  • Its prevalence estimates range from 1 in 40,000 to 1 in 300,000 births.
  • It is caused by a deficiency of the enzyme acid alpha-glucosidase (GAA).
    • GAA enzyme is crucial for breaking down glycogen into glucose within the cells.
  • Symptoms: Muscle weakness, motor skill delay, degenerative impact on bones, respiratory complications, and hypertrophic cardiomyopathy.
  • Treatment: Currently, there exists no cure for Pompe disease.
  • Hypertrophic cardiomyopathy: It is characterised by the thickening of the heart muscle walls.

{GS3 – Envi – CC Impact} WMO Report on Melting of Glaciers

  • Context (TH I Dtnpf): The World Meteorological Organization (WMO) published a report titled “The Global Climate 2011-2020: A Decade of Acceleration”.

Findings of the report on melting of glaciers

  • Unprecedented glacial melting: Glaciers worldwide thinned by approximately 1m annually between 2011 and 2020 due to global warming.
    • The Antarctic ice sheet lost 75 per cent more than the previous ten years.
    • Glaciers near the Equator are generally in rapid decline.
    • Glaciers in Papua, Indonesia, will likely disappear within the next decade.
    • Greenland and Antarctica lost 38% more ice from 2011 to 2020 than in the previous decade.

Other findings of the report

  • 2011-2020 was the warmest decade on record: Global mean temperature for 2011- 2020 was 1.10 ± 0.12 °C above the industrial revolution era.
    • The decade 2011-2020 emerged as the warmest on record for both land and ocean.
    • Global mean sea level rise accelerated to 4.5mm/yr from 2011-2020, mainly due to ocean warming and ice mass loss.
  • Atmospheric concentration of CO2: Since the industrial revolution, CO2 has increased by nearly 50%, contributing to global warming.
  • Ocean warming: Between 2011-20, the oceans warmed at an increased rate contributing to marine heatwaves, sea level rise, ocean acidification, and tropical cyclones.
    • In any given year between 2011 and 2020, approximately 60% of the surface of the ocean experienced a heatwave.
    • Warming oceans and melting of ice sheets caused the rate of sea-level rise to nearly double.
    • Ocean acidification due to CO2 absorption poses challenges for marine organisms, affecting their shell and skeleton formation.
  • Extreme events: Between 2011-2020, heatwaves were responsible for the highest number casualties, while tropical cyclones caused the most economic damage.
  • Ozone hole recovery: The ozone hole was smaller in 2011-2020 than during the previous two decades.
    • The success is mainly attributed to the Montreal Protocol, which banned chlorofluorocarbons.
    • Efforts led to reduced chlorine entering the stratosphere from ozone-depleting substances.


  • Glaciers are a large, dense body of ice that moves slowly under its own weight.
  • They are a part of the Earth’s Cryosphere.
  • The cryosphere encompasses all frozen parts of the Earth.
  • Glaciers cover about 10% of the Earth’s land surface.


Significance of glaciers

  • Global climate regulation: Glaciers keep the Earth’s climate mild due to their high albedo.
  • Source of fresh water: About three-quarters of Earth’s freshwater is stored in glaciers.

Glaciers of India and the World

  • The majority of the world’s glaciers are in the polar regions, mainly Antarctica, Greenland, and Canadian Arctic.
  • Lambert Fisher Glacier in Antarctica is the largest glacier in the world.
  • Outside the polar regions, the Hindu Kush-Karakoram-Himalayan system (HKKH) contains the largest number of glaciers, often called the ‘Third Pole’ of the Earth.
    1. Important glaciers of India

Important Glaciers in India

Impacts of Glacial Melting

  • Sea level rise: Melting glaciers have raised sea levels by 2.7 centimetres since 1961.
  • Ice-albedo feedback loop: It refers to a process where melting ice reduces Earth’s overall reflectivity, absorbing more sunlight, further accelerating warming and ice melt, creating a self-reinforcing cycle (positive feedback loop) in climate change.
  • Changes in global ocean circulation due to changes in the distribution of freshwater.
  • Threat to coral reefs: Rising sea levels prevent corals from receiving adequate sunlight.

Global initiatives

  • International Cryosphere Climate Initiative (ICCI): A network of senior policy experts and researchers working with governments to preserve as much of the Earth’s cryosphere as possible.
  • Global Cryosphere Watch (GCW): It’s a joint initiative of the World Meteorological Organization (WMO), which monitors the cryosphere.
  • Arctic Council: Set up in 1996 by the Ottawa Declaration to promote cooperation and coordination among the Arctic States. It is mandated to protect the Arctic environment.

Initiatives by India

  • National Mission for Sustaining the Himalayan Ecosystem (NMSHE): It is one of the eight missions under NAPCC and encompasses conservation measures for sustaining and safeguarding the Himalayan ecosystems.

World Meteorological Organisation (WMO)

  • It is an intergovernmental organisation with 192 Member States (India is a member).
  • It originated from the International Meteorological Organization (IMO), established after the 1873 Vienna International Meteorological Congress.
  • WMO was established by the ratification of the WMO Convention in 1950.
  • WMO became the specialised agency of the United Nations for meteorology (weather and climate), operational hydrology and related geophysical sciences.
  • Headquarters: Geneva, Switzerland.

{GS3 – Envi – UNFCCC} Nuclear Energy for Net Zero Emission

  • Context (IE): Led by the US, 22 countries, including France, the UK, Japan, Canada, S. Korea and Ukraine, pledged to triple global nuclear capacity by 2050 for a net-zero emissions goal at COP28.
  • India abstains from the nuclear energy commitment, aligning with its position not to join alliances outside the COP process.
  • Objectives of the pledge:
    • Keeping global warming below 1.5°C from pre-industrial times (Paris Agreement).
    • Ensuring net-zero emissions.
  • Commitments:
    1. Mobilise investment and urge financial institutions like the World Bank to back nuclear power.
    2. Efforts to extend the life of existing plants
    3. Support for new technologies like small modular reactors (SMRs)

Small Modular Reactors (SMRs)

  • SMRs are smaller, simpler, and more affordable than traditional nuclear reactors.
  • They typically have a power capacity of up to 300 MW(e), which is about 1/3rd of the generating capacity of traditional nuclear power reactors.

Net-Zero Emissions

  • Net zero emissions refers to the balance between the amount of greenhouse gas (GHG) produced and the amount removed from the atmosphere.
  • To keep global warming below 1.5°C from pre-industrial times, emissions must be reduced by 45% by 2030 and reach net zero by 2050.
  • India has set its target to reach net-zero emissions by 2070.

Significance of Nuclear Energy for Net-Zero Emissions

Clean Energy

  • Nuclear energy is a non-renewable energy source that does not emit greenhouse gases.
  • In 50 years, nuclear power prevented nearly 70 billion tonnes of CO2 equivalent emissions.

High Energy Density

  • Nuclear reactors generate a large amount of energy from a small amount of fuel.
  • This reduces the need for land use compared to other renewable energy sources like solar or wind.

Resilient Energy Source

  • Nuclear power plants are not susceptible to weather fluctuations like wind or solar energy.
  • This makes it a reliable source of power.

Present Status of Nuclear Energy

  • Currently, 31 countries have 370 GW of operational nuclear power capacity, contributing 10% of the world’s total electricity, as per the International Atomic Energy Agency (IAEA).
  • A tripling will see this increase to at least 1,000 GW by the middle of the century.

Challenges for the Nuclear Sector to Meet Net-Zero Emission Target

  • High initial investment: Complex technology makes building new nuclear power plants expensive.
  • Decommissioning costs: Dismantling nuclear plants at the end of their lifespan is complex and costly.
  • Time limit: It took 70 years to bring global nuclear capacity to the current level of 370 GW, and now the industry must build another 740 GW in half that time.
  • Safety concerns: E.g., the Chernobyl and Fukushima disasters.
  • Nuclear waste disposal: Safe, long-term storage for radioactive waste is vital for the sustainability of nuclear energy.
  • Thermal pollution: Nuclear plants release heated water, impacting aquatic ecosystems.
  • Public perception: Public concerns about safety, waste disposal, and nuclear weapons proliferation can limit public support for nuclear energy.
  • Regulatory framework: Complex regulations can increase costs and delays in nuclear projects.
  • Fuel availability: While uranium resources are relatively abundant, supply chain risks and geopolitical factors necessitate careful planning and source diversification.

Other Initiatives in the Nuclear Sector for Net-Zero Emissions

Net Zero Nuclear

  • Net Zero Nuclear is an initiative by the World Nuclear Association (WNA) and the Emirates Nuclear Energy Corporation.
  • It is supported by the IAEA Atoms4NetZero Initiative launched in COP27.
