New Indian Express
Illustration for India Aluminium Industry Stress (Aluminium Industry)

What & Where

Metal; lightweight, corrosion-resistant; core uses windows, doors, cookware, vehicles, solar frames

Process; refined from bauxite into alumina, then smelted via electricity-intensive Hall–Héroult method

Geography; richest Indian bauxite belts Odisha Koraput–Sundergarh, Jharkhand Lohardaga, Gujarat Kutch

Quick Facts for MCQs

Economic Angle

  • Utilisation only 40 % of 3 mtpa capacity, straining profitability
  • Demand merely 4 kg per capita versus 11 kg global average
  • Potential growth drivers include electric vehicles and solar infrastructure

Trade Dynamics

  • ASEAN FTA and varied HSN codes enable duty-free, cheaper inflows
  • Imports >1.5 mt already exceed domestic extrusion output 1.2 mt
  • Trade gap risks plant shutdowns, job losses, current-account strain

Environmental Impact

  • UPVC, oil-derived, raises lifecycle emissions conflicting with Paris targets
  • Aluminium infinitely recyclable; substitution weakens circular-economy gains
  • Plastic waste adds landfill burden and microplastic pollution

Key Data Points

2.Atmanirbharta Roadmap for Indian Millets (Millet Self-Reliance)

NITI Aayog

What & Where

Definition : Nutri-cereals like jowar, bajra, ragi; thrive in arid, rain-fed soils.

Geography : Rajasthan, Maharashtra, Karnataka, Uttar Pradesh & Madhya Pradesh ≈ 80 % of national output.

Global spot : India tops with 41 % of world millet production (~16 MT/yr).

Quick Facts for MCQs

Production & Trade

  • Output-boost: Cluster approach, rice-fallow expansion, bio-fortified hybrids recommended.
  • Trade-push: GI-tagged brands, buyer–seller meets, APEDA support for Middle-East/EU.
  • Regional skew: Western & peninsular belts dominate; east holds expansion potential.

Nutrition & Climate

  • Micronutrients: Rich iron, calcium, fibre — combats anaemia & malnutrition.
  • Resilience: Survives drought, poor soils; low input cuts fertiliser & irrigation dependence.
  • SDG link: Climate-smart millet farming aligns with adaptation & sustainable diets goals.

Policy & Schemes

  • NFSM-Millets: Seed minikits, area expansion, productivity demos since 2018-19.
  • Shree Anna Mission: 6-year drive for R&D, processing, branding, market integration.
  • Scheme integration: Mid-Day Meal, ICDS, PDS urged to ensure assured domestic demand.

Challenges

  • Price-bias: Rice/wheat MSP + irrigation subsidies discourage millet acreage.
  • Value chain gaps: Thin FPO coverage, weak procurement, limited processing tech.
  • Productivity lag: Sparse R&D, hybrid seeds → yields below cereals benchmark.

3.Lipulekh Himalayan Pass (High Mountain Pass)

The Hindu

What & Where

High-altitude Himalayan pass at 5,334 m, traditional trade–pilgrimage route linking India and Tibet (China).

Sited in Pithoragarh district, Uttarakhand; lies just west of India-Nepal-China trijunction.

Forms gateway for Kailash Mansarovar Yatra; India’s first border-trade post with China (1992).

Quick Facts for MCQs

Geopolitical Significance

  • Trijunction: critical for surveillance, logistics, and force projection in central Himalayas.
  • Trade-route: facilitates limited India-Tibet commerce despite overall border closure.
  • Terrain: narrow ridge, rugged approaches; natural chokepoint for movement.

India–Nepal Boundary Dispute

  • India: treats Lipulekh–Kalapani–Limpiyadhura as longstanding admin part of Uttarakhand.
  • Nepal: 2020 constitutional map extended western boundary to Mahakali River’s headwaters, covering pass.
  • Negotiations: no agreed boundary settlement; Nepal raised issue again at SCO 2025.

China’s Stance

  • Non-interference: terms area an India-Nepal bilateral matter, avoids formal alignment.
  • Trade priority: continues Lipulekh barter route with India, signaling status-quo preference.
  • Diplomatic leverage: pass offers China indirect influence in India-Nepal relations.
