Lightning kills more than 2,000 Indians every year, more than any other natural disaster. Strikes have increased 400% between 2019 and 2025.

• Annual deaths: over 2,000 per year, making lightning India's single deadliest natural disaster by annual mortality count.
• Strike increase: 400% rise in total lightning strikes between 2019 and 2025.
• Annual growth rate: 7-14% per year in lightning frequency, directly linked to rising surface temperatures and atmospheric moisture content.
• Warming mechanism: warmer air holds more water vapour. Greater moisture and instability intensify convective storms, which are the primary source of lightning.
• New hotspots: traditionally lightning deaths were concentrated in Odisha, Jharkhand and Bihar. New hotspots are now forming in Rajasthan, Gujarat, Haryana, Punjab and Delhi as warming expands the zone of convective activity.
• NDMA response apps:
  • Damini: real-time lightning location and early warning.
  • Mausam: general weather forecasting with storm alerts.
  • Sachet: multi-hazard early warning for all NDMA-notified disasters.
• Mitigation scheme: the Mitigation Project on Lightning Safety (MPLS) and the Lightning Resilient India Campaign focus on community awareness, lightning conductors for public buildings and real-time alert dissemination.
• Seasonal pattern: most deaths occur between April and June (pre-monsoon) and during the monsoon months in eastern and central India.

The Supreme Court's acceptance of the Centre's 100-metre elevation definition for Aravalli Hills represents a narrowing of environmental protection that experts argue violates the precautionary principle.

• Court order (November 20, 2025): the SC accepted the Centre's definition that only land at 100 metres elevation or above qualifies as "Aravalli Hills" for protective purposes.
• Area at risk: up to 60% of the broader Aravalli landscape, which sits below the 100-metre threshold, may now be accessible to mining, quarrying and construction.
• Precautionary principle: a foundational principle in environmental law stating that where there is scientific uncertainty about environmental harm, the lack of certainty does not justify inaction or removal of protection. Its application is inconsistent in Indian judicial decisions.
• Climate barrier function: the Aravalli range blocks dust-laden winds from the Thar Desert from reaching the NCR. A significant reduction in vegetation will worsen air quality and dust storms in Delhi.
• Groundwater recharge: the Aravalli ridge recharges the aquifers that supply groundwater to eastern Rajasthan, Haryana and parts of Delhi.
• Wildlife corridor: the forested patches in the Aravalli hills form a critical movement corridor linking Sariska Tiger Reserve and Ranthambhore National Park. Fragmentation isolates tiger populations.
• Relevant legal framework: Forest Conservation Act 1980; the 1996 TN Godavarman SC order defining "forest" broadly; Environment Protection Act 1986.

India's three-tier consumer dispute redressal system has 5.43 lakh cases pending as of January 2024, with a structural mismatch between filing rates and disposal capacity.

• Pending cases: 5.43 lakh cases across all tiers of the consumer dispute redressal system (District Commissions, State Commissions and the National Commission) as of January 2024.
• Statutory time limit: the Consumer Protection Act 2019 mandates disposal within 3-5 months of filing.
• New additions: approximately 15,000 cases were added to the backlog in 2024-25, indicating the system is disposing fewer cases than it is receiving.
• Vacancy problem: hundreds of judicial and administrative posts across the commissions are vacant, directly reducing disposal capacity.
• Consumer Protection Act 2019: replaced the Consumer Protection Act 1986. Introduced e-filing and video-conferencing for hearings. Established the Central Consumer Protection Authority (CCPA) as a regulator. Added product liability provisions.
• Three-tier structure:
  • District Consumer Disputes Redressal Commission: claims up to Rs 1 crore.
  • State Consumer Disputes Redressal Commission: claims between Rs 1 crore and Rs 10 crore.
  • National Consumer Disputes Redressal Commission: claims above Rs 10 crore.

The Haka, a traditional Maori performance from Aotearoa (New Zealand), came into global spotlight as an act of cultural assertion and non-violent protest during December 2025.

• Origin: the Haka is an indigenous performance tradition of the Maori people of Aotearoa (New Zealand).
• Mythological roots: rooted in the mythology of Tane-rore, son of Tama-nui-te-ra (the sun god) and Hine-raumati (the summer maid). The shimmering of hot air was the first haka.
• "Ka Mate" haka: created by the Ngati Toa chief Te Rauparaha around 1820, celebrating survival after he hid from enemies in a food storage pit. It is the most widely recognised haka internationally.
• Types of haka:
  • Ka Mate: survival and gratitude.
  • Peruperu: a war dance performed with leaping.
  • Ngeri: a short energising haka without weapons.
  • Powhiri: a welcoming ceremony haka.
  • Manawa wera: a mourning haka.
• Cultural significance: the Haka is both a living art form and a political symbol. It has been used by Maori communities as a form of non-violent assertion of rights and cultural identity.
• New Zealand context: Maori are recognised as the indigenous tangata whenua (people of the land) under the Treaty of Waitangi (1840), New Zealand's founding document.

DRDO completed User Evaluation Trials of the Akash-NG (New Generation) surface-to-air missile system, advancing it toward induction.

• Type: surface-to-air missile system designed to intercept and destroy aircraft, drones, helicopters and cruise missiles.
• Developer: Defence Research and Development Organisation (DRDO).
• Seeker: the key upgrade is an indigenous Radio Frequency (RF) seeker, replacing the earlier radar beam-riding guidance of the legacy Akash system. The RF seeker enables active terminal homing, improving accuracy.
• Propulsion: dual-pulse solid rocket motor, which allows two separate thrust phases. The second pulse is triggered as the missile approaches the target.
• Radars: fully indigenous multi-function phased array radar and command guidance systems.
• Purpose: Akash-NG upgrades and eventually replaces the legacy Akash missile batteries in service with the Indian Army and Air Force.
• Legacy Akash: developed by DRDO and produced by BEL (Bharat Electronics Limited). India's first indigenously developed medium-range SAM system.

The Commission for Air Quality Management issued show-cause notices to six thermal power plants operating near the NCR for failing to comply with biomass co-firing requirements.

• CAQM: Commission for Air Quality Management in the National Capital Region and Adjoining Areas. Established under the Commission for Air Quality Management in National Capital Region and Adjoining Areas Act 2021.
• Replaced: the Environment Pollution (Prevention and Control) Authority (EPCA), which had been the earlier statutory body for air quality in the NCR.
• Jurisdiction: covers the National Capital Region and parts of the adjoining states of Haryana, Punjab, Rajasthan and Uttar Pradesh.
• Biomass co-firing: thermal power plants in the region are required to co-fire a specified proportion of agricultural biomass (crop residue) as fuel alongside coal. This reduces coal consumption and provides farmers an alternative to stubble burning.
• Stubble burning link: the non-compliance notices are significant because biomass co-firing directly competes with on-field stubble burning as a disposal method. If plants do not buy crop residue, farmers have less economic incentive to avoid burning.
• CAQM composition: Chairperson, Member-Secretary, three technical experts and three non-governmental organisation representatives.

China filed a complaint at the World Trade Organization against India's subsidy and tariff measures covering solar panels, electric vehicles and batteries.

• Complainant: China.
• Respondent: India.
• Items challenged: solar panel subsidies under India's production-linked incentive schemes; tariff measures on Chinese EVs and batteries; domestic content requirements in solar tenders.
• Legal grounds alleged: violation of bound tariff commitments (WTO Schedules) and national treatment obligations under GATT Article III (treating imported goods less favourably than domestic goods).
• WTO dispute process: a request for consultations triggers a 60-day consultation window. If unresolved, the complainant may request a panel. Panel formation to final report typically takes 12-18 months. Both sides may appeal to the Appellate Body, which is currently dysfunctional due to US blocking of appointments.
• India's likely defence: national security and climate-related industrial policy grounds, both of which are contested but recognised exceptions in WTO law.
• Broader context: India has been expanding domestic manufacturing of solar and EV components under the Atmanirbhar Bharat initiative, directly competing with Chinese exports.

India's first medical colleges built under a Public-Private Partnership model are being established in the tribal districts of Dhar and Betul in Madhya Pradesh.

• Districts: Dhar and Betul, both scheduled district tribal areas in Madhya Pradesh.
• Total planned: four medical colleges across the two districts.
• Funding model: Viability Gap Funding of up to 40% of total project cost provided by the government to make the project financially viable for private operators.
• Financing institution: IIFCL (India Infrastructure Finance Company Limited) provides long-term project finance.
• FDI: 100% foreign direct investment is permitted in the medical education sector, enabling international hospital groups to participate.
• Problem addressed: tribal districts in India have severe shortages of doctors and medical infrastructure. Most medical colleges are concentrated in urban, non-tribal areas.
• MBBS seats impact: each college creates approximately 100-150 MBBS seats, directly increasing the supply of doctors trained with exposure to tribal health challenges.

Events around Christmas 2025 involving allegations of communal incidents in parts of India renew attention to the constitutional framework for religious freedom.

• Article 25: guarantees freedom of conscience and the right to freely profess, practise and propagate religion. This right is subject to public order, morality and health, and to other Fundamental Rights.
• Article 26: guarantees every religious denomination (or any section thereof) the right to establish and maintain institutions for religious and charitable purposes, manage its own affairs in matters of religion, and own and administer property.
• Limitations on Article 25: the State may regulate secular activities associated with religious practice. It may legislate for social welfare and reform even against the claims of a religious institution.
• Propagation clause: India is among a small number of constitutional democracies that explicitly protects the right to propagate religion, which has been interpreted to include peaceful religious conversion.
• Forcible conversion laws: several Indian states have enacted laws requiring prior notice or approval for conversions, which are contested against Article 25's propagation right in ongoing litigation.

• CAQM Act 2021 gives the Commission overriding powers: its directions prevail over any directions issued by state governments or other statutory bodies in the NCR region for air quality management.
• Damini app was developed by IITM Pune (Indian Institute of Tropical Meteorology) in collaboration with IMD. It identifies lightning strikes within 20 km and 40 km radii and issues alerts.
• Viability Gap Funding is a scheme of the Ministry of Finance providing government grants to make commercially unviable but socially necessary infrastructure projects viable for private investment.
