LIFTING OF EXPORT BAN ON NON-BASMATI WHITE RICE
TOPIC: (GS3) ECONOMY: INDIAN EXPRESS
The Indian government recently lifted the ban on the export of non-basmati white rice but imposed a Minimum Export Price (MEP) of $490 per tonne. This decision comes after a marginal dip in rice production last year and other factors that influenced the ban in the first place. The change is expected to impact both domestic and global rice markets, influencing prices and trade dynamics.
Why was the ban imposed?
- Marginal dip in production: The export ban was originally imposed due to a slight reduction in rice output, which raised concerns about food security. It aimed to control domestic supply and prevent inflation of rice prices.
- Erratic monsoon: Unpredictable monsoon patterns threatened rice production, leading to cautionary measures like banning exports.
Reasons for lifting the ban now:
- Higher Sowing: With a favourable monsoon this year, there has been increased sowing activity. Farmers have reported more planting, with data indicating a total of 413.50 lakh hectares, a 2.2% increase compared to the previous year.
- Record Production: The Agriculture Ministry estimates that India’s total rice production during 2023-24 will reach 137.82 million tonnes, 1.5% higher than last year. This rise in output has eased concerns over domestic supply.
- Stable Prices: Wholesale rice prices have also declined, reflecting the improved supply situation. The wholesale price index for rice was recorded at Rs 3,324.99 per quintal, lower than the Rs 3,597.99 reported a month ago.
- Surplus Stocks: India has substantial stockpiles of rice, including non-basmati varieties. The Central rice stock pool stood at 323.11 lakh tonnes as of September 1. This surplus allows for the resumption of exports without significant risk to domestic markets.
Likely Impacts of the Move:
- Global Market Supply: India is the world’s second-largest rice exporter, and lifting the export ban will significantly impact global markets.
- Non-basmati rice, which accounted for 25% of India’s total rice exports, is expected to return to international markets, easing the supply shortage in several countries.
- Price Effects: While the MEP of $490 per tonne will regulate exports, it may still lead to price volatility in international markets. However, the increase in global supply is expected to stabilize prices over time.
- Impact on Indian Farmers: Indian farmers, particularly those producing premium non-basmati varieties, will benefit from the resumption of exports as they can now access international markets and earn higher prices for their produce.
- Domestic Consumer Concerns: For domestic consumers, there may be concerns about potential price increases as the demand for exports rises. However, the government has ensured that rice stocks remain adequate, and measures like the MEP aim to prevent significant price hikes.
- Competitors in Global Markets: India’s main competitors in rice exports, particularly Thailand and Vietnam, may face increased competition as Indian rice returns to the global market. In the 2023 season, these two countries accounted for significant portions of global rice exports, but India’s return could shift the dynamics.
India’s Rice Export Landscape:
- Broad categories of exports: India’s rice exports are broadly categorized into basmati and non-basmati varieties.
- In 2023-24, basmati rice accounted for about 45.61 lakh tonnes, while non-basmati white rice exports had dipped due to the ban.
- Major Export Destinations: Indian non-basmati rice is exported to various countries, including Nepal, Bangladesh, and parts of Africa.
- Vietnam and Thailand are India’s major competitors in the non-basmati rice market.
- Growth in Exports: There has been a notable jump in the export of husked (brown) rice, with shipments increasing by 301.31 lakh tonnes in 2023-24.
- Broken rice and other rice in husk also saw fluctuations due to the restrictions, but exports are expected to stabilize as the ban is lifted.

EARTH’S SURVIVAL AFTER THE SUN’S DEATH: INSIGHTS FROM A NEW STUDY
TOPIC: (GS3) SCIENCE AND TECHNOLOGY: INDIAN EXPRESS
A recent study has revealed the possibility of Earth surviving the death of the Sun, offering fascinating insights into the fate of planets orbiting dying stars.
The research focuses on a rocky planet orbiting a white dwarf star, giving scientists clues about what might happen to Earth in the distant future.
Findings:
- Observation of a Rocky Planet: Astronomers discovered a rocky planet, 1.9 times larger than Earth, orbiting a white dwarf star, 4,200 light-years away. The study, published in Nature Astronomy, highlights how planets can remain in orbit even after their stars have died.
- The Sun’s Future: The Sun is predicted to become a white dwarf after it expands into a red giant, shedding its outer layers. This will happen over the next several billion years, as the Sun depletes its nuclear fuel and loses mass.
- Planetary Survival: The planet observed survived the death of its star and continues to orbit the white dwarf. This discovery hints that Earth, although severely affected, might also survive the Sun’s transition into a white dwarf. However, the planet would become cold and barren, possibly unable to sustain life.
Formation of a Star
- Cloud Dust (Stellar Nursery): Stars begin forming in vast clouds of gas and dust known as “stellar nurseries” (e.g., Orion Nebula). Turbulence within these clouds creates denser regions, initiating gravitational collapse to form a protostar.
- Protostar: A protostar is the early stage of star formation, where the core becomes dense and hot. It attracts surrounding gas and dust, eventually becoming a young star.
- T Tauri Star: A T Tauri star is a young star still contracting before reaching the main sequence. These stars show strong stellar winds and variations in brightness.
Main Sequence Stars
- Main Sequence Phase: Stars spend most of their life in the main sequence phase, where nuclear fusion of hydrogen to helium occurs in their cores. Our Sun is currently a main sequence star.
- Equilibrium: Main sequence stars are in hydrostatic equilibrium, where the inward pull of gravity is balanced by the outward pressure from nuclear fusion in the core.
- Fusion: Nuclear fusion in the core sustains the star, converting hydrogen into helium. This is the longest and most stable phase of a star’s life.
- Lifespan: The lifespan of a main sequence star depends on its mass:
- Massive stars burn fuel quickly and live only for a few million years.
- Smaller stars, such as red dwarfs, can last for tens of billions of years.
Death of a Star
- Red Giant/Supergiant Phase:
When a star exhausts its hydrogen, it expands into a red giant or supergiant. Helium fusion begins in the core, and hydrogen fusion continues in outer layers. The Sun will become a red giant in about 5 billion years.
- Planetary Nebula:
In stars like the Sun, outer layers are ejected, forming a glowing shell of gas and dust called a planetary nebula. The remaining core becomes a white dwarf.
- White Dwarf:
A white dwarf is the leftover core of a star. It no longer undergoes fusion but remains hot and dense. These remnants are stable due to electron pressure, provided their mass is under the Chandrasekhar limit (1.4 solar masses).
Stellar Explosions
- Nova Explosion: In binary star systems, white dwarfs can pull in hydrogen from a companion star, leading to nuclear fusion and a bright explosion called a nova.
- Supernova Explosion: Massive stars (more than 8 solar masses) end their lives in supernova explosions. When the core collapses, it creates a shockwave and an explosion, leaving behind either a neutron star or a black hole.
Neutron Stars and Black Holes
- Neutron Stars: Stars with cores between 1.4 and 3 solar masses collapse into neutron stars, incredibly dense objects primarily composed of neutrons.
- Pulsars and Magnetars: Some neutron stars emit radiation beams, which, if observed from Earth, appear as pulsars. Magnetars are neutron stars with extremely strong magnetic fields.
- Black Holes: If the stellar core is more than 3 solar masses, it collapses into a black hole, an entity with such intense gravity that not even light can escape.
Chandrasekhar Limit: Key Points
The Chandrasekhar Limit is the maximum mass (approximately 1.4 solar masses) that a white dwarf can have before it becomes unstable and cannot support itself against gravitational collapse.
- Named after Indian astrophysicist Subrahmanyan Chandrasekhar, who calculated this limit in 1930.
White Dwarfs:
- White dwarfs are remnants of stars that have exhausted their nuclear fuel and expelled their outer layers.
- They are supported by electron degeneracy pressure, which arises from the Pauli exclusion principle.
Implications of Exceeding the Limit:
- If a white dwarf’s mass exceeds the Chandrasekhar Limit, it cannot maintain stability and will collapse.
- This collapse can lead to two possible outcomes:
- Type Ia Supernova: If the white dwarf is part of a binary system and accretes mass from a companion star, it may eventually undergo a thermonuclear explosion, resulting in a Type Ia supernova.
- Neutron Star or Black Hole Formation: If the core’s mass exceeds the limit after collapse, it can become a neutron star or a black hole.
Astrophysical Significance:
- The Chandrasekhar Limit plays a crucial role in understanding stellar evolution, particularly the end stages of low to medium-mass stars.
- It helps explain the processes leading to supernovae and the formation of more dense remnants in the universe.
Conclusion:
The study opens new avenues for understanding the life cycles of stars and the potential fates of their orbiting planets. While Earth may survive the Sun’s eventual demise, it would likely become an inhospitable, frozen world. These findings help scientists refine their predictions about planetary systems and the evolution of stars.
Multiple choice question:
- Identify the correct matches among the following celestial objects:
- Cepheids: Massive clouds of dust and gas in the universe.
- Nebulae: Stars that exhibit periodic brightening and dimming.
- Pulsars: Neutron stars resulting from the collapse of massive stars after exhausting their fuel.
How many of the above descriptions are accurately paired with the respective celestial objects?
- Only one
- Only two
- All three
- None
Answer: A
Explanation
Cepheids: This description is incorrect. Cepheid variables are not giant clouds of dust and gas; they are a type of variable star that pulsates regularly, leading to variations in brightness. They are often used as standard candles in astronomy to measure distances.
Nebulae: This description is also incorrect. Nebulae are not stars; they are large clouds of gas and dust in space. Some nebulae are regions where new stars are forming, while others are remnants of dead or dying stars.
Pulsars: This description is correct. Pulsars are indeed neutron stars formed from the remnants of massive stars that have undergone supernova explosions. They emit beams of radiation that can be detected as they rotate.
INDIA’S SPACE PROGRAMME: STEADY PROGRESS BUT REQUIRES MORE RESOURCES
TOPIC: (GS3) SCIENCE AND TECHNOLOGY: THE HINDU
India’s space programme, led by the Indian Space Research Organisation (ISRO), has made significant strides, particularly with missions like Chandrayaan-3. However, despite these achievements, the programme faces challenges due to limited resources.
The global space race is heating up, with countries aiming for significant commercial and geopolitical gains, especially with lunar exploration.
Challenges Faced by Global Space Missions:
- In July, NASA cancelled its Volatiles Investigating Polar Exploration Rover (VIPER) mission to the moon. This mission, meant to explore water-ice in the moon’s south pole, was cancelled due to delays and cost overruns.
- VIPER’s cancellation drew the attention of international space communities, as it was set to play a key role in NASA’s Artemis Accords, which aim to establish a lunar exploration framework involving multiple nations, including India.
- The cancellation of such a high-profile mission underscores the time and financial costs associated with lunar exploration, even for well-funded agencies like NASA.
India’s Response to Lunar Exploration:
- India, through ISRO, achieved a significant milestone with the successful Chandrayaan-3 mission in August 2023. India became part of an elite group of countries capable of autonomous lunar soft landings.
- The next step for India’s lunar programme is Chandrayaan-4, a sample-return mission approved by the Union Cabinet in September 2023. However, there is concern that India is missing key opportunities in the evolving lunar race.
India’s Missed Opportunities:
- Unlike other space agencies, ISRO tends to focus on one major mission at a time, which optimises resource use but limits its ability to pursue multiple high-profile missions simultaneously.
- A significant opportunity was missed when ISRO could not immediately push for the approval of its planned Lunar Polar Explorer mission in collaboration with Japan. This mission, if prioritised, could have filled the gap left by NASA’s cancelled VIPER mission, particularly in prospecting for water-ice deposits on the moon.
- India’s participation in the global lunar exploration race could have been enhanced if ISRO had the capability to respond quickly to emerging opportunities like VIPER’s cancellation.
Need for More Resources in India’s Space Programme:
- Despite receiving an expanding budget and new funding mechanisms, ISRO’s resources remain limited compared to other major space agencies.
- The Chandrayaan-3 mission demonstrated India’s capabilities, but to maintain momentum and keep up with international developments, ISRO needs increased investment. This will allow it to conduct multiple flagship missions in parallel and contribute more significantly to global initiatives like the Artemis Accords.
- With more resources, India could increase its geopolitical and commercial influence in the space sector, particularly in areas like lunar exploration, where new discoveries, such as water-ice, hold potential for future human settlements.
Conclusion:
India’s space programme has achieved significant milestones, such as the successful Chandrayaan-3 mission. However, the global space race is intensifying, particularly in lunar exploration. While ISRO has been efficient with its resources, its inability to execute multiple flagship missions at once is a limitation. To fully realise its potential and keep pace with international competitors, ISRO needs increased funding and resources. This will enable India to not only maintain its current trajectory but also respond to new opportunities and enhance its role in the evolving space landscape.

GENETIC DIVERSITY LOSS IN INDIAN ELEPHANTS:
TOPIC: (GS3) ENVIRONMENT: THE HINDU
A genomic study conducted by researchers from the National Centre for Biological Sciences (NCBS) and the Indian Institute of Science (IISc) has revealed significant insights into the genetic diversity of Indian elephants.
By analyzing the genomes of these majestic animals, the study tracks their historical migrations across India, uncovering a decline in genetic diversity over time.
Key Findings
Migration Patterns and Genetic Divergence
Distinct Populations: The research identified five genetically unique populations of elephants in India.
- The northern population diverged first, approximately 70,000 years ago.
- The central population followed, splitting around 50,000 years ago.
- The southern populations diverged last, about 20,000 years ago.
Loss of Genetic Diversity
- Serial Founder Effect: As elephants migrated southward, they experienced a loss of genetic diversity, primarily due to the “serial founder effect.” This phenomenon occurs when a small group of individuals establishes a new population, carrying only a fraction of the genetic diversity of the larger original population.
- Vulnerability of Southern Populations: The southernmost elephant population, located south of the Shencottah Gap, is particularly vulnerable, with fewer than 150 elephants remaining.
Southern Elephant Populations
- The study reshapes previous notions about elephant dispersal in the Western Ghats.
- It identified three distinct populations in the south:
- North of the Palghat Gap.
- Between the Palghat and Shencottah Gaps.
- South of the Shencottah Gap.
Northern and Central Populations
- The northern elephant population is found along the foothills of the Himalayas.
- Central Indian elephants inhabit areas from southwestern West Bengal to eastern Maharashtra, representing another distinct genetic group.
- Natural barriers like the Ganga and Brahmaputra rivers further delineate these populations.
