More recently, the Kambala Samithi hosts weekly events from the end of November till the 1st half of April across Dakshina Kannada and Udupi districts in Karnataka.

  • A folk sport practised in coastal Karnataka districts, especially in regions where Tulu speakers form a majority.
  • Harvest festival – It will be organised in the slushy paddy fields, in the days after the harvest from November to March.
  • Pairs of buffaloes are groomed by Bunt community in the coastal regions around the year.
  • 4 categories
    • Negilu (plough) – Lighter ploughs are used to tie buffaloes which is for entry-level buffalo pairs.
    • Hagga (rope) – Buffaloes are raced by jockeys with just a rope tied to both buffaloes.
    • Adda Halage – Participants stand over a horizontal plank which is dragged by buffaloes.
    • Kane Halage – Participants stand over a wooden plank which has 2 holes through which water gushes out.
  • Ban – Supreme Court ruled to ban Jallikattu, Kambala and bullock cart racing in 2014.
  • Later, the Environment Ministry and State governments made provisions to exempt these events in recognition of the customs and cultural heritage of various communities, which was upheld by the Supreme Court bench in 2023.

Article 29 (1) of Indian constitution is a fundamental right guaranteed under Part III to protect the educational and cultural rights of citizens.

Basic Animal Husbandry Statistics 2023

The Basic Animal Husbandry Statistics 2023 was released during National Milk Day in 2023.

  • It is a survey of milk, egg, meat and wool production in India based on Animal Integrated Sample Survey (ISS) conducted between March 2022-February 2023.
  • The survey is conducted in 3 seasons - summer (March-June), monsoon (July-October) and winter (November-February).


  • Key finding - Production of milk, egg and meat has significantly gone up in 2022-23 over the past five years, although wool output in the same period has witnessed a negative growth.

India celebrates National Milk Day on November 26th, to commemorate the efforts of Dr Verghese Kurien, the father of White Revolution.

Recently, astronomers have detected a rare and extremely high-energy particle falling to Earth.

  • It is one of the most powerful cosmic rays slamming into Earth and has been named "Amaterasu" after the Japanese sun goddess.
  • These ultra-high energy particle passes atmosphere smoothly without any deflection by magnetic fields.
  • Spotted by Telescope Array observatory in Utah, a collaboration of the United States, Japan, Korea, Russia, and Belgium to observe cosmic rays.
  • Energy – It exceeds 240 exa-electron volts (EeV), millions of times more powerful than the particles produced by the Large Hadron Collider, which is the most powerful accelerator ever built.
  • It is 2nd only to the ‘Oh-My-God’ particle, another high-energy cosmic ray at 320 EeV that was detected in 1991.
  • Source – Only the most powerful cosmic events, on scales far exceeding the explosion of a star, are thought to be capable of producing such energetic particles.
  • But Amaterasu appears to have emerged from the Local Void, an empty area of space bordering the Milky Way galaxy.

Cosmic Rays

  • A radiation that is constantly rains down on Earth from space.
  • Properties – They are electrically charged and so deflected by various magnetic fields throughout the galaxy.
  • Detection - The rays don't point directly back to their sources.
  • Composition – They are mainly protons (89%) but also includes nuclei of helium (10%) and heavier nuclei (1%).
  • Impact – When they crash into our atmosphere, they are broken up and fall to Earth in even smaller fragments.
  • Significance – Helps in understanding the chemical evolution of the universe.
  • Reasons for non-detection
    • It could be from a source that we have not yet identified.
    • It might have been magnetically deflected much higher than current models predict.
    • Scientists might need to rewrite their incomplete understanding of high-energy particle physics.

Mangroves as Carbon Sink

Volunteers in Chargheri village of Sunderbans help in planting lakhs of mangroves which offer a dense forest cover and a rich carbon sink.

The Sunderbans is a complex network of islands set in the delta on the Bay of Bengal and spread across West Bengal and Bangladesh.

  • Blue carbon – It is coined in 2009, a term for carbon captured by and stored in the world’s ocean and coastal ecosystems.
  • Key ecosystems of blue carbon - Mangroves, salt marshes and seagrass meadows
  • These ecosystems sequester and store more carbon per unit area than terrestrial forests.


  • Mangroves as carbon sink – After seagrass, mangroves are the most efficient carbon trapping systems which can remove 10 times more carbon from the air than other forests.
  • While other trees release the stored carbon back to atmosphere when they die, mangroves transfer the carbon to the soil, where it stays unaffected even if the tree is destroyed.

Mangrove Initiatives

  • Mangrove Initiative for Shoreline Habitats and Tangible Incomes (MISHTI) – It was launched by India in 2023 to protect and revive mangrove ecosystems on the Indian coast.
  • Mangrove Alliance for Climate (MAC) – It was launched at CoP-27 (Egypt, 2022) to unite countries to scale up, accelerate conserve and restore the mangrove ecosystems.
  • After the devastation caused by Cyclone Amphan in 2020, West Bengal Chief Minister had announced that 5 crore mangroves would be planted in the Sunderbans under the Mahatma Gandhi National Rural Employment Guarantee Act.

Compulsory Blending Obligation (CBO) of CBG

The National Biofuels Coordination Committee (NBCC) gave its nod to mandatory blending of compressed biogas (CBG) with compressed natural gas (CNG) and piped natural gas (PNG) from 2025-26.

  • Biogas - It is an energy-rich gas produced by anaerobic decomposition of biomass.
  • Sources include Agriculture residue, cattle dung, sugarcane press mud, municipal solid waste, and sewage treatment plant waste, among others.
  • It can be burnt directly as a fuel, or purified and upgraded by removing carbon dioxide, hydrogen sulfide, and then compressed to make compressed Biogas (CBG).
  • CBG – It has more than 90% of methane, which is similar to commercially available natural gas in composition and energy potential.

Sustainable Alternative Towards Affordable Transportation (SATAT) scheme was launched in 2018, under which 5,000 CBG plants were envisaged by 2023 to produce 15 million tonnes of CBG.

  • Compulsory blending obligation – It will be
    • 1 % of total CNG and domestic PNG consumption for FY26
    • 3 % for FY27
    • 4 % for FY28
    • 5 % blending from FY29
  • A Central Repository Body (CRB) will be responsible for monitoring and implementing the blending mandate.
  • Objectives – It aims to
    • Stimulate demand for CBG in city gas distribution sector
    • Import substitution for liquefied natural gas (LNG) thus saving forex
    • Promote circular economy for achieving the target of net-zero emission, etc

Picture of India’s Gas Sector

  • India is a major consumer of natural gas and depends on imports to meet around half of its requirement.
  • It aims to increase the share of natural gas in the primary energy mix to 15% by 2030 from a little over 6% at present.
