🔆 Microbial Link Between Arsenic & Rice Yield
📍 Source – Proceedings of the National Academy of Sciences (PNAS)

📍 Key Findings
It’s not the soil arsenic levels alone, but the type of microbes in rice paddies that determines arsenic toxicity and crop loss.
Arsenic-methylating bacteria convert inorganic arsenic into toxic compounds (DMA, DMMTA), while demethylating archaea help detoxify the soil.
A high ratio of methylating to demethylating microbes increases the risk of “straighthead disease”, causing up to 70% yield loss.
Soils older than 700 years show more demethylating microbes — safer for crops.

📍 Implications
Managing microbial balance may be key to reducing arsenic buildup in rice grains.
Climate change and altered flooding regimes can worsen microbial imbalance, heightening risk.
India — the world’s second-largest rice producer — must prioritize soil microbiome monitoring to protect yield and food safety.

Future rice security depends as much on managing microbes as on managing soil.

📍 Mains Question:
Discuss how microbial activity in paddy soils influences arsenic toxicity and its implications for food safety and agricultural sustainability in India.

🔆 Mud Volcano Eruption in Baratang Island (Andaman & Nicobar Islands)

📍 Recent Event
India’s only active mud volcano in Baratang Island has erupted after 20 years, releasing mud, gases, and water.

📍 About Mud Volcanoes
Definition: Natural vents that expel a mix of mud, water, and gases (mainly methane, sometimes CO₂ or nitrogen) — not molten lava.
Formation Areas: Common in natural gas–rich regions.
Cause of Eruption: Triggered by tectonic pressure or hydrocarbon gas buildup beneath the surface.
Structure: Forms cone-like mounds, mimicking true volcanic shapes.

🔆 Does India’s 1.9 Fertility Rate Reflect Reality?

📍 Key Idea:
India’s Total Fertility Rate (TFR) — reported at 1.9 by the UN Population Fund — signals sub-replacement fertility, but the figure may understate real fertility trends due to methodological and demographic limitations.

TFR is a synthetic measure based on age-specific fertility rates (ASFR) observed at a single point in time, assuming current fertility patterns remain constant. This ignores delayed childbearing, especially among younger women, leading to an artificially low TFR. Rural areas show a clear postponement pattern — fertility has shifted from women aged 15–19 to the 25–34 cohort.

Additionally, underreporting of births, exclusion of late-age fertility (40–49), and concealed births among adolescents distort data. Experts argue that India’s “real” fertility might be slightly higher than reported, and that sub-replacement fertility doesn’t automatically guarantee population stability due to youth bulge and regional disparities.

📍 Mains Question:
➡️ Critically evaluate whether India’s Total Fertility Rate (TFR) accurately reflects ground realities. How do methodological gaps influence demographic planning?

🔆 Centre Withdraws Approval for Animal Protein-Based Biostimulants

📍 Context:
The Central Government has withdrawn approval for animal protein-based biostimulants citing religious and dietary sensitivities.

📍 About Biostimulants
Definition: Substances or microorganisms that enhance plant growth by improving nutrient uptake, efficiency, and resilience to abiotic stresses (like drought, salinity, or heat).
Examples: Humic acids, seaweed extracts, liquid manure compost, beneficial bacteria & fungi.
Category: Officially distinct from fertilisers and insecticides, as they promote growth through biological stimulation rather than direct nutrient supply.

🔆 Typhoon Ragasa: The Year’s Strongest Storm

📍 About Typhoon Ragasa
Super Typhoon Ragasa, locally known as “Nando,” is one of the most powerful tropical cyclones of 2024.
It affected Luzon (Philippines), Taiwan, South China, Hong Kong, Macau, and Vietnam, before weakening into a tropical depression over northeastern Vietnam.
It formed over the warm waters of the western Pacific, moving through the Luzon Strait toward southern China.
Classified as a Category 5 super typhoon, Ragasa recorded sustained winds of 280 km/h, nearing the maximum intensity possible for storms on Earth.

📍 Why Was Ragasa So Intense?
Rising global temperatures have made tropical cyclones more powerful, with the Pacific Ocean warming by 1.5°C in the past century.
Storms in Southeast Asia are forming closer to coastlines, intensifying faster, and lasting longer.
Warm ocean waters and a track over open seas helped Ragasa maintain its strength without losing energy over land.

📍 About Super Typhoons
Super typhoons are powerful Pacific tropical cyclones with sustained winds above 150 mph (240 km/h).
They form from tropical disturbances over warm ocean waters with low wind shear.
Common in the Western Pacific, near China, Japan, and the Philippines.

📍 About Tropical Cyclones
A tropical cyclone is a warm-core low-pressure system forming over tropical or subtropical waters with an organized circulation.
The storm’s “dirty side” (right side in the Northern Hemisphere) is usually more destructive due to stronger combined winds.
Formation Process:
1️⃣ Warm, moist air rises over the ocean, creating a low-pressure zone.
2️⃣ Surrounding air rushes in, also warming and rising.
3️⃣ Condensation forms clouds and thunderstorms, releasing heat.
4️⃣ The storm system strengthens using the ocean’s heat and moisture.

📍 Saffir-Simpson Hurricane Wind Scale
Category 1: 74–95 mph – Minimal damage
Category 2: 96–110 mph – Moderate damage
Category 3: 111–129 mph – Major hurricane
Category 4: 130–156 mph – Catastrophic damage
Category 5: ≥157 mph – Devastating damage

📍 Classification of Tropical Systems
Tropical Depression: Winds <63 km/h
Tropical Storm: Winds 63–118 km/h
Hurricane/Typhoon/Cyclone: Winds ≥119 km/h

📍 Current Status (2024)
🌧️ Ragasa has weakened to a tropical depression over northeastern Vietnam, but continues to bring heavy rainfall to northern provinces.

Named by Thailand, “Montha” means “fragrant flower” in Thai.

📍 Impact Areas:
Affected Tamil Nadu, Odisha, and coastal Telangana with widespread rainfall and gusty winds.
High risks of flooding, strong winds, and damage to homes and crops.

📍 Intensification:
The system intensified into a deep depression by 26 October and became a cyclonic storm.
Favourable conditions: Warm sea temperatures (>28°C), low wind shear, and ample moisture support intensification.

📍 Future Outlook:
IMD forecasts the storm may become a Severe Cyclonic Storm before landfall.

💬 Mains Q:
Discuss the preparedness measures required to mitigate the effects of cyclones like Montha on coastal states.

🔆 India’s Position in Rare Earth Elements (REEs)

📍 REE Potential
India holds around 6% of the world’s rare earth reserves, indicating significant untapped resources.

📍 Import Dependency
In FY 2023–24, India imported 2,270 tonnes of REEs, showing a moderate dependence on external sources.

📍 Light REE Capabilities
India can extract light REEs from monazite-rich beach sands, particularly along the coasts of Kerala.

📍 Heavy REE Refining Deficit
India lacks the technological and industrial infrastructure to refine heavy REEs, which creates a strategic vulnerability in the critical minerals supply chain.

🔆 China’s Position in the REE Market

📍 Market Monopoly
China holds a monopoly in the global REE market.
It accounted for more than 2/3rd of mined REEs last year.
China produces nearly 90% of global refined REE output.

📍 Rare-Earth Magnets Supply
China also dominates the supply of rare-earth magnets.

📍 Recent Trade Curbs
China’s recent export curbs on 12 rare-earth elements have reignited trade tensions globally.

🔆 Mains Question
Q. “Climate justice has a fair price tag of trillions, not billions.” Discuss the importance of robust climate finance in addressing the climate crisis and how it impacts the Global South’s trust in COP negotiations.

📍 Key Issues:
Climate Justice must be built on fair financing for vulnerable regions, not just a symbolic commitment.
Poor Quality & Quantity of Finance: Global South’s trust in climate negotiations is waning due to lack of adequate funding.
COP30 in Brazil: The potential for global collaboration exists, but real support is still lacking, hindering long-term progress.
Green Climate Fund: Though aimed at bridging the finance gap, it falls short of delivering the promised funds, impeding effective climate action.

📍 India’s Role:
India calls for stronger global financial commitments, urging for trillions in climate finance, rather than billions.
Promoted global partnerships like the Coalition for Disaster Resilient Infrastructure.
