• West Asia: US threatened to strike Iranian oil wells and desalination plants if Iran did not reopen Hormuz.
• Economy: IIP data for February: 5.2 per cent growth, with capital goods at 12.5 per cent.
• Polity: North-South delimitation debate intensified with India completing the 2026 census enumeration phase.
• LWE: March 31 anti-Maoist deadline reached; Home Minister's press conference.
• Science: Parkinson's disease treatment breakthrough: the SCAN network combined with a TMS protocol.
• PMUY: 1 in 4 PMUY beneficiaries uses only 1 LPG refill per year, revealing implementation gaps.

US President Trump issued a direct threat to Iran:

• The threat: If Iran did not reopen the Strait of Hormuz within 72 hours, the US would strike Iranian oil export facilities at Kharg Island and major desalination plants.
• Kharg Island: Located in the Persian Gulf, processes about 90 per cent of Iran's oil exports. Destroying it would collapse Iran's oil revenue.
• Desalination plants: Iran's Persian Gulf coastline is arid. Major cities (including oil facilities) depend on desalination. Destroying desalination would create humanitarian crisis conditions.
• International reaction: China, Russia, and India issued statements calling for restraint. The UN Secretary-General called for immediate negotiations.
• India's oil exposure: India's 65-day crude buffer began when Iran closed Hormuz. At 72 hours from this point, India had approximately 60 days of buffer remaining. The 72-hour deadline created a new time pressure.
• Brent crude response: Brent crude spiked to $118 per barrel on the news.

GS area: Economy (industrial output)

The Index of Industrial Production (IIP) for February 2026 was released:

• Overall growth: 5.2 per cent year-on-year.
• Capital goods: 12.5 per cent growth. Capital goods are machinery, equipment, and plant used in production. Their strong growth indicates business investment in productive capacity.
• Consumer durables: 7.3 per cent. Household goods like washing machines, refrigerators.
• Consumer non-durables: 2.1 per cent. Food and personal care products.
• Infrastructure/construction goods: 6.4 per cent. Cement, steel, construction materials.
• Interpretation: Capital goods growth at 12.5 per cent suggests sustained private investment despite West Asia headwinds. The 5.2 per cent overall IIP growth is solid for an economy managing $108 crude.
• IIP composition: Mining (14.4 per cent weight), Manufacturing (77.6 per cent), Electricity (7.9 per cent). Manufacturing drives the overall number.
• Base effect: February 2025 IIP growth was only 3.8 per cent, providing a low base.

An official review of the Pradhan Mantri Ujjwala Yojana revealed structural implementation issues:

• The finding: 1 in 4 PMUY beneficiaries took only 1 LPG refill in the entire year.
• PMUY context: Provides free LPG connections to women from BPL households. 10.35 crore connections distributed since 2016.
• Why refill rates are low:
  • Refill cost: ₹913 per cylinder as of March 2026 (following the recent LPG hike). For a rural BPL family earning ₹8,000 to ₹10,000 per month, a single cylinder costs 10 per cent of monthly income.
  • Traditional cooking fuels (firewood, biomass, dung cakes) are free. LPG is a cash expense.
  • Availability: In remote areas, LPG distributors are far away. Transport cost adds to the effective price.
• The scheme's intent vs. reality: PMUY was designed to address indoor air pollution and improve women's health. Low refill rates mean households revert to biomass, negating the health benefit.
• Policy gap: The scheme provided connections but not sustained affordability. A connection subsidy without a refill subsidy for the poorest quintile is structurally incomplete.
• PAHAL (JAM DBT): LPG subsidies are transferred directly to beneficiaries' bank accounts after they buy the cylinder at market price. PMUY beneficiaries receive an additional subsidy. But even with this subsidy, the affordability gap exists.

GS area: Polity (elections)

March 31 marked the completion of India's 2026 census enumeration phase:

• Census process: House listing and housing census (2025) followed by population enumeration (January-March 2026). Data compilation and release will take 12 to 18 months.
• Delimitation trigger: After census data is released, the Delimitation Commission (headed by a retired Supreme Court judge) will redraw Lok Sabha and state assembly constituency boundaries.
• The North-South divide:
  • States that controlled population growth (TN, Kerala, Andhra, Telangana, Karnataka) will see smaller seat gains relative to their economic size.
  • States with higher population growth (UP, Bihar, Madhya Pradesh, Rajasthan) will see disproportionate seat gains.
• The 91st Amendment (2003): Capped the total strength of Lok Sabha at 543 seats (the same as 1977). Redrawing boundaries within this fixed total is a zero-sum game.
• Constitutional option: A constitutional amendment to change the delimitation criterion from population alone to population plus development indicators (HDI, fertility rate, sex ratio).

Indian researchers (AIIMS Delhi, NIMHANS Bengaluru) reported findings on a new Parkinson's treatment protocol:

• The SCAN network: Striatal-Cerebellar-Amygdalo-Nigral network. A newly identified brain network involved in Parkinson's pathology. Published in Nature Neuroscience (January 2026) by a UK-India collaborative team.
• TMS (Transcranial Magnetic Stimulation): A non-invasive brain stimulation technique. Uses magnetic pulses to stimulate specific brain regions without surgery.
• The protocol: Targeted TMS of specific nodes in the SCAN network in Parkinson's patients reduced tremor intensity by 40 per cent in early-stage patients over a 12-week protocol.
• Significance:
  • Current Parkinson's treatments (L-DOPA, DBS -- deep brain stimulation) have significant side effects or require invasive surgery.
  • TMS is non-invasive, reversible, and can be done in outpatient settings.
• Parkinson's in India: Estimated 1 million patients. Second most common neurodegenerative disorder after Alzheimer's. Incidence growing with an ageing population.

GS area: Polity (rights, federalism)

Karnataka introduced the Karnataka Prevention of Wrongful Conversion of Religion Bill 2026:

• Background: Similar laws exist in Madhya Pradesh (Freedom of Religion Act 2021), Uttar Pradesh (Freedom of Religion Act 2021), Uttarakhand, and Himachal Pradesh.
• Karnataka's Bill provisions:
  • Conversions by force, fraud, allurement, or marriage are criminalised.
  • District Magistrate must be informed before and after conversion.
  • Burden of proof on the converter to prove the conversion was free and voluntary.
• Constitutional position: Article 25 guarantees freedom of conscience, the right to profess, practise, and propagate religion. Propagation includes the right to persuade others.
• SC on conversions: The Court in Stainislaus v. State of Madhya Pradesh (1977) held that the right to propagate does not include the right to convert another person by force, fraud, or allurement.
• The tension: The line between persuasion (protected) and allurement (banned) is contested. Critics argue these laws are used to harass minority communities and prevent legitimate conversion.
