The PRB was operationalised on 9 May 2025 under the Payment and Settlement Systems Act 2007, though its work programme for 2026 is in focus this week.

• Chairperson: RBI Governor (ex-officio).
• Composition: RBI Deputy Governor, government nominees and fintech experts.
• Functions: Authorises new payment systems, sets operational standards, manages settlement finality and supervises payment service providers.
• Predecessor: Replaced the Board for Payment and Settlement Systems (BPSS), which was an internal RBI committee. The PRB has a statutory basis, giving it more independent authority.
• Distinction: The PRB regulates the payment infrastructure. The RBI regulates banks and NBFCs. The boundary matters for MCQ traps.

The Somnath Temple observed 1,000 years since Mahmud of Ghazni's raid of 1026 CE.

• Location: Prabhas Patan, Veraval, Saurashtra, Gujarat.
• Jyotirlinga status: One of 12 Jyotirlingas, the most sacred Shiva shrines in India.
• Destruction and reconstruction cycle: The temple was destroyed six times across medieval history by different rulers. It was rebuilt each time by local rulers.
• 1026 CE attack: Mahmud of Ghazni's raid is the most historically documented destruction, connected to the transfer of enormous temple wealth.
• Post-independence reconstruction: Initiated by Sardar Vallabhbhai Patel in 1947-51. He pushed for reconstruction despite the sensitive political climate. It was inaugurated on 11 May 1951 by President Rajendra Prasad after Patel's death.
• Prelims trap: The reconstruction is associated with Patel, not Nehru, though the Congress government of the time had reservations.

The world's second NESL was inaugurated at CSIR-NPL (National Physical Laboratory), New Delhi.

• Function: Tests and calibrates air pollution monitoring equipment under Indian climatic conditions, ensuring the instruments measure accurately in the country's temperature, humidity and dust conditions.
• First NESL: Located in the United Kingdom. Only two countries (UK and India) have such national-level facilities.
• Link to NCAP: Supports the National Clean Air Programme (NCAP), which targets 20 to 30% reduction in PM2.5 and PM10 concentrations by 2024 (now revised for 2026).
• CSIR-NPL: India's primary national metrology institute. It maintains the country's measurement standards in time, frequency, mass, temperature and now air quality.

A detailed assessment of climate finance needs for the Hindu Kush Himalaya (HKH) region reveals a massive gap between need and actual spending.

• India's annual need: Approximately 102 billion USD for adaptation and mitigation in India's HKH territories.
• Total HKH need: Approximately 768.7 billion USD annually. China's share is 605 billion (due to larger territory) and India's is 102 billion.
• HKH span: Eight countries (Afghanistan, Pakistan, India, Nepal, Bhutan, Bangladesh, China, Myanmar).
• Population dependence: Nearly half the global population depends on water resources and ecosystem services from the HKH.
• Priority sectors for spending: Agriculture, water resources, energy and urban development in mountain zones.

A gender analysis of India's renewable energy workforce reveals structural inequalities despite macro-level progress.

• Women's labour force participation: 41.7% versus 78.8% for men.
• Productivity link: A 1% rise in gender diversity in a firm correlates with approximately 2.9% higher labour productivity (economic research finding).
• Renewable energy workforce: Women constitute about 32% globally but are clustered in non-STEM and administrative roles rather than technical work.
• Waste pickers: Approximately 1.5 million women work as waste-pickers (about 49% of the total), earning around 33% less than men.
• Policy gap: Climate insurance, skill certifications and asset ownership programmes that explicitly target women are largely absent from India's green transition framework.

The GEF approved 52.8 million USD for four UNEP-led projects at its 70th Council meeting.

• Established: 1991, headquartered in Washington D.C.
• Financial mechanism for: Convention on Biological Diversity (CBD), UNFCCC, UNCCD (desertification), Stockholm Convention (persistent organic pollutants) and Minamata Convention (mercury).
• Scale: Mobilised 153 billion USD in co-financing globally. Operates in 160-plus countries.
• Structure: Separate from the World Bank though hosted initially by it. GEF has its own governance structure with recipient country representation.
• Largest multilateral biodiversity funder: Relevant for questions on biodiversity finance alongside the Global Biodiversity Framework's 30x30 target.

Nationwide protests swept Iran from 28 December 2025 with bazaar shutdowns. The geography is essential prelims material.

• Location: Southwestern Asia, bridging the Middle East, Central Asia and South Asia.
• Capital: Tehran.
• Borders: Azerbaijan, Armenia, Turkmenistan (north and northeast); Caspian Sea (north); Afghanistan, Pakistan (east); Turkey, Iraq (west); Persian Gulf, Strait of Hormuz, Gulf of Oman (south).
• Key physical features: Central Iranian Plateau (containing the Dasht-e Kavir and Dasht-e Lut deserts), Zagros Mountains (NW-SE), Alborz Mountains (Caspian coast), Mount Damavand (Iran's highest peak).
• Only navigable river: Karun River.
• Economic crisis: The rial depreciated to roughly 1.45 million per USD by January 2026. Infrastructure protests focus on fuel prices, water shortages and unemployment.

India inaugurated the world's fifth National Primary Standard Facility for Solar Cell Calibration at CSIR-NPL.

• Technology: Laser-based Differential Spectral Responsivity (L-DSR) system.
• Accuracy: Achieves 0.35% (k=2) calibration uncertainty, matching the best international standards.
• Development partner: Germany's Physikalisch-Technische Bundesanstalt (PTB), the national metrology institute.
• Significance: A national calibration standard means solar panels manufactured in India can be tested to internationally recognised benchmarks without sending samples abroad, reducing certification time and cost.

• Infrastructure: Bamboo construction, nature walk trails, interpretation centres and school outreach programmes.
• Nocturnal wildlife: The site hosts nocturnal species that are not typically visible to daytime visitors of urban green spaces.
