The 8th Pay Commission was formally constituted by the Union Cabinet.

• Previous Pay Commission timeline: the 7th Pay Commission was constituted in 2014 and submitted its report in November 2015. Implementation from 1 January 2016.
• Fitment factor: in the 7th Pay Commission, the fitment factor was 2.57, which multiplied the basic pay across all grades uniformly.
• Pay Commission coverage: approximately 50 lakh central government employees and 65 lakh pensioners.
• Armed forces: a separate Anomaly Committee reviews defence pay issues that emerge from each commission.
• Key terms:
  • Basic pay: the fixed component before allowances.

The UNEP Adaptation Gap Report 2025 was released, finding a USD 310-365 billion annual shortfall in adaptation financing.

• What is adaptation: adjusting to current and future climate impacts, as distinct from mitigation (reducing emissions).
• Adaptation examples: seawalls for coastal flooding; drought-resistant crop varieties; early warning systems for cyclones; heat action plans for urban areas.
• UNEP report findings: adaptation finance received by developing nations is approximately USD 28-35 billion/year. Required: USD 338-400 billion/year. Gap: USD 310-365 billion/year.
• India's adaptation priorities:
  • Coastal protection (West Bengal, Odisha mangroves; Gujarat saline ingress).
  • Drought-resistant seeds under ICAR.
  • National Action Plan on Climate Change (NAPCC): 8 missions including National Water Mission and National Mission for Sustainable Agriculture.
• National Adaptation Fund for Climate Change (NAFCC): GoI scheme providing grants to state governments for adaptation projects.
• Loss and Damage Fund: agreed at COP27 (2022), operationalised at COP28 (2023). Separate from the adaptation gap; covers irreversible losses.
• IPCC's AR6 adaptation chapter: found many current adaptation efforts are "fragmented, incremental and not transformative."

The 2017 National Transit Oriented Development (TOD) Policy was evaluated in the context of metro expansion across India.

• TOD concept: high-density, mixed-use development within walking distance (400-800 metres) of public transport nodes such as metro stations and bus rapid transit (BRT) stops.
• Ministry: Housing and Urban Affairs (MoHUA).
• 2017 National TOD Policy targets: floor-area-ratio (FAR) of 4 within 500 metres of metro stations; dedicated affordable housing quotas; commercial-residential integration.
• Implementation gap: most city master plans still retain low FAR zones near metro stations. Vested interests in low-density layouts and parking infrastructure prevent reform.
• Metro network: India's operational metro network is 968 km (as of October 2025) across 20 cities. Delhi Metro is the largest (392 km).
• Success cases: Hyderabad's HITEC City BRT corridor (partial TOD). Mumbai's Dharavi redevelopment plan incorporates TOD principles.
• Fiscal rationale: higher development density near metro stations increases property tax revenues, which can be reinvested in metro maintenance (Land Value Capture).

The NEP 2025-26 implementation committee announced plans to introduce Artificial Intelligence (AI) as a formal subject from Class 3 onwards in all central government schools.

• Starting grade: Class 3 (age 8-9). Age-appropriate curriculum based on AI literacy: understanding how machines learn, simple categorisation tasks, bias in data.
• CBSE's AI curriculum (existing): elective subject from Class 9. The new rollout makes a simplified foundational version compulsory from Class 3.
• NEP 2020 basis: NEP 2020's Technology Integration pillar mandates computational thinking from primary school.
• International comparison: Finland introduced coding from Class 1 in 2016. Singapore has AI literacy from Class 4. China mandated AI education in primary schools from 2017.
• Infrastructure gap: 43 per cent of government schools lack reliable electricity; 31 per cent lack internet connectivity. The AI rollout includes tablet/device provision under PM-eVIDYA.
• PM-eVIDYA: one-class-one-channel DTH satellite education channels (Swayam Prabha) and digital content portals (DIKSHA). These serve schools without reliable internet.
• Ethical concern: AI literacy must include data privacy, algorithmic bias and responsible use of AI tools.

• Atal Pension Yojana (APY) milestone: APY crossed 7 crore enrolments in October 2025. APY provides guaranteed monthly pension of Rs 1,000 to Rs 5,000 for workers in the unorganised sector who join between 18-40 years. PFRDA (Pension Fund Regulatory and Development Authority) administers it.
• Nipah Virus vigilance: Kerala High Level Committee reviewed Nipah virus preparedness. Nipah is a zoonotic virus (bat origin) with a fatality rate of 40-75 per cent. No approved vaccine. Kerala has had four outbreaks (2018, 2019, 2021, 2023).
• Coffee Board of India: notified draft Coffee (Promotion and Development) Act 2025, replacing the Coffee Act 1942. Targets doubling coffee exports from USD 1.2 billion to USD 2.5 billion by 2030. India produces Arabica and Robusta varieties (Karnataka, Kerala, Tamil Nadu).
