South Africa hosted the G20 Summit in Johannesburg in 2025. The summit produced a 122-paragraph declaration but faced a significant dissent from the United States, which declined to endorse the final text.

• Climate finance commitment: the declaration commits to scaling climate finance "from billions to trillions." The Cost of Capital Commission for the Global South was established to identify structural barriers that raise borrowing costs for developing economies.
• Nelson Mandela Bay Target: the declaration commits to reducing the share of youth who are Not in Education, Employment or Training (NEET) by 5 percentage points by 2030 in Africa. Named after the city in Eastern Cape where it was agreed.
• Mission 300: a joint G20 and African Union initiative to bring electricity to 300 million people in Sub-Saharan Africa by 2030.
• Absent major powers: the United States, China, and Russia were absent from or did not endorse parts of the declaration. US refusal to endorse the text is the most significant constraint on implementation.
• G20 structure: the G20 comprises 19 countries plus the European Union and the African Union (full member from 2023). India held the G20 Presidency in 2023 and hosted the New Delhi Summit.
• South Africa's presidency: South Africa became the first African country to hold the G20 Presidency. The 2025 Johannesburg Summit was the culmination of that presidency.

The Ministry of Textiles launched the TEX-RAMPS scheme (Textiles Research and Manufacturing for Productivity and Sustainability) with an outlay of Rs 305 crore covering 2025 to 2031.

• Full form: TEX-RAMPS stands for Textiles Research and Manufacturing for Productivity and Sustainability (approximate expansion; scheme branding by Ministry of Textiles).
• Budget: Rs 305 crore over the 2025-31 period.
• Component 1: advanced research and development in smart textiles. Smart textiles integrate electronic, thermal, or chemical functionality into fabric structures. Applications include wearable health sensors, defence camouflage, and moisture-management sportswear.
• Component 2: Integrated Textiles Statistical System (ITSS). This creates a unified data platform for the textile sector, currently fragmented across multiple ministries and industry bodies. Reliable statistics are a prerequisite for evidence-based policy.
• Component 3: capacity development and start-up support. Includes incubation funding, skill development linkages, and support for textile technology start-ups.
• Strategic context: India is the world's second-largest producer and exporter of textiles. The sector employs approximately 45 million people directly and 100 million indirectly. Smart and technical textiles are the fastest-growing sub-segment globally.
• Technical textiles policy: India's National Technical Textiles Mission (2020-26) provides the broader policy framework within which TEX-RAMPS operates.

GS area: GS-3 (environment, pollution, tribunals)

The National Green Tribunal directed the Central Pollution Control Board, the Kerala State Pollution Control Board, and the Plantation Corporation of Kerala to trace and account for missing Endosulfan barrels in Kasaragod district.

• Endosulfan: an organochlorine pesticide. Banned in India in 2011 under the insecticide regulations framework. Covered under the Stockholm Convention on Persistent Organic Pollutants.
• Kasaragod context: Endosulfan was aerially sprayed on cashew plantations managed by the Plantation Corporation of Kerala in Kasaragod district over several decades. Communities reported elevated rates of neurological disorders, cancers, and congenital anomalies. The government accepted the linkage and provided compensation.
• NGT establishment: the National Green Tribunal was established on 18 October 2010 under the National Green Tribunal Act, 2010.
• NGT jurisdiction: the NGT adjudicates civil cases involving substantial questions relating to the environment. It covers disputes under the Water (Prevention and Control of Pollution) Act, the Air (Prevention and Control of Pollution) Act, the Environment Protection Act, and the Forest Conservation Act.
• Acts excluded from NGT jurisdiction: the Wildlife Protection Act, 1972; the Indian Forest Act, 1927; and the Scheduled Tribes and Other Traditional Forest Dwellers (Recognition of Forest Rights) Act, 2006. Cases under these Acts go to regular courts.
• Chairperson qualification: the Chairperson of the NGT must be a retired Judge of the Supreme Court or a retired Chief Justice of a High Court.

The ICMR Antimicrobial Resistance Surveillance Network (AMRSN) published its 2025 annual report documenting the spread of drug-resistant pathogens across Indian hospitals.

• Resistant infections: common infections including urinary tract infections, pneumonia, bloodstream sepsis, and diarrhoea are increasingly caused by drug-resistant organisms.
• Key resistant organisms: Escherichia coli (E. coli), Klebsiella pneumoniae, Acinetobacter baumannii, and Pseudomonas aeruginosa are showing high rates of resistance to fluoroquinolones, cephalosporins, and carbapenems.
• Carbapenem significance: carbapenems are considered last-resort antibiotics for multi-drug-resistant infections. Resistance to carbapenems leaves very few treatment options. Colistin is sometimes used as a final option but carries severe side effects.
• Causes of AMR: antibiotic misuse (prescribing without culture-based diagnosis), incomplete dosing by patients, excessive use in livestock and aquaculture, and horizontal gene transfer between bacteria in hospital environments.
• India's AMR burden: India accounts for the largest absolute number of AMR-attributable deaths globally, partly because of population size and partly because of high rates of unregulated antibiotic dispensing.
• National Action Plan on AMR: India launched its National Action Plan on AMR in 2017, aligned with the WHO Global Action Plan. Progress on implementation has been inconsistent.

GS area: GS-3 (Indian economy, statistics, data quality)

The International Monetary Fund assessed India's national accounts statistics as "C" grade in its quality evaluation framework, citing methodology gaps and data reliability concerns.

• IMF grading: the IMF uses a data quality assessment framework with grades. A "C" grade indicates significant methodological shortcomings that limit the reliability of the data.
• Base year problem: India's national accounts use 2011-12 as the base year. A base year that is more than a decade old fails to reflect structural changes in the economy and the relative weights of different sectors.
• Price deflation gap: India uses the Wholesale Price Index (WPI) for deflating some national accounts series rather than a full Producer Price Index (PPI). The WPI does not capture service sector price movements. This creates gaps in real GDP measurement.
• Expenditure-production gap: there is a large and persistent gap between the expenditure-side GDP estimate and the production-side GDP estimate. This gap is an indicator of measurement errors.
• CPI grade: India's Consumer Price Index received a better "B" grade from the IMF, indicating fewer methodological concerns.
• Methodology used: India's national accounts are compiled using the UN System of National Accounts 2008 (SNA-2008) framework, which is the current international standard.
• Policy relevance: GDP estimates drive fiscal calculations (the fiscal deficit is expressed as percentage of GDP), resource allocation, and comparisons with other economies. A "C" grade weakens confidence in these numbers.

GS area: GS-1 (physical geography, disaster management)

Cyclone Ditwah formed in the southwest Bay of Bengal and intensified rapidly before making landfall, affecting the coasts of Tamil Nadu, Andhra Pradesh, and Puducherry.

• Formation: the depression formed in the southwest Bay of Bengal and intensified to a cyclonic storm within 24 hours, classified as rapid intensification.
• Name origin: the name "Ditwah" was recommended by Yemen. Under the World Meteorological Organisation's rotation system, nations in the North Indian Ocean region take turns naming cyclones.
• Impact geography: Tamil Nadu, Andhra Pradesh, and Puducherry lie on the Coromandel Coast, which faces the Bay of Bengal and receives the northeast monsoon in October and November.
• October-November cyclone season: this period features high sea surface temperatures (28 to 30 degrees Celsius and above) across the Bay of Bengal. Low vertical wind shear during this season allows cyclones to intensify without disruption from high-altitude winds.
• Cyclone classification in India: the India Meteorological Department classifies disturbances as depression (winds 31-61 kmph), cyclonic storm (62-88 kmph), severe cyclonic storm (89-117 kmph), very severe (118-167 kmph), extremely severe (168-221 kmph), and super cyclonic storm (above 221 kmph).
• Rapid intensification: defined by the WMO as an increase in maximum sustained winds of at least 35 knots (approximately 65 kmph) within 24 hours. Climate change is increasing the frequency of rapid intensification events globally.

A 37,000-year-old bamboo fossil discovered in Manipur provides the oldest evidence of thorny bamboo in Asia, revealing that defence adaptations in bamboo evolved during the Ice Age.

• Discovery location: silt deposits of the Chirang River in Manipur, Northeast India.
• Age: approximately 37,000 years old. This places it in the Late Pleistocene epoch, during the last glacial period (Ice Age).
• Species identified: Chimonobambusa manipurensis. The species name reflects both the genus and the discovery location.
• Preserved features: thorn scars, nodes, and buds are clearly visible in the fossil, allowing definitive identification of thorny bamboo morphology.
• Significance: this is the earliest fossil evidence of thorny bamboo in Asia. The findings prove that herbivore-defence traits (thorns) in bamboo evolved during the Ice Age rather than later, providing insight into plant-herbivore co-evolution.
• Northeast India as refugium: the fossil evidence supports the hypothesis that Northeast India functioned as a climatic refugium during glacial periods. A refugium is an area where species survive while conditions elsewhere make survival impossible.
• Bamboo ecology: India is home to approximately 136 bamboo species. The northeast region holds the highest bamboo diversity. Bamboo forests have significant carbon sequestration and livelihood roles.

GS area: GS-3 (food safety, public health, regulation)

State food safety inspectors found Auramine O, an industrial synthetic dye, being illegally used to colour food products to imitate turmeric or saffron.

• What it is: Auramine O is a synthetic diarylmethane dye. It produces a bright yellow colour. Its primary legitimate uses are as a fluorescent biological stain in laboratory settings and in industrial dyeing of leather and paper.
• Legal status in food: Auramine O is not permitted as a food colour under Indian food safety regulations. The Food Safety and Standards Authority of India (FSSAI) prohibits its use in any food product.
• Misuse pattern: the dye is used to make cheaper food items appear to be coloured with turmeric or saffron. Turmeric and saffron are expensive, making adulteration profitable.
• Health risks: Auramine O causes liver damage, kidney damage, and spleen enlargement with repeated exposure. It disrupts the endocrine system. The International Agency for Research on Cancer (IARC) classifies it as Group 2B: possibly carcinogenic to humans.
• Detection: fluorescence microscopy can detect Auramine O at trace levels. Standard food safety field tests may not distinguish it from permitted dyes, making laboratory analysis necessary.
• Regulatory framework: the Food Safety and Standards Act, 2006 and regulations made under it govern food additives, contaminants, and adulterants in India. FSSAI is the implementing authority.

• G20 African Union membership: the African Union was admitted as a full G20 member at the New Delhi Summit in September 2023 under India's presidency. This gave Africa a permanent seat at the G20 table for the first time.
• Stockholm Convention on Persistent Organic Pollutants was adopted in 2001 and entered into force in 2004. India is a signatory. Endosulfan was added to Annex A (elimination) at the fifth Conference of Parties in 2011.
• ICMR AMRSN is one of the most comprehensive drug-resistance surveillance networks in the developing world. It collects data from over 20 tertiary care hospitals and tracks resistance trends by organism and drug class.
• WPI vs PPI: the Wholesale Price Index measures price changes at the producer level for goods traded in bulk markets. A Producer Price Index is broader and includes services. India does not publish a full PPI, which is a recognised gap in its price statistics.
