2.India Inland Water Transport (Inland Waterways)

PIB

What & Where

Inland Waterway: navigable river/lake/canal supporting ≥50-ton vessels; India possesses 14,500 km such stretches.

National Waterway-57: 44 km Kopili River, Assam; fourth operational NW in state after Brahmaputra-2, Barak-16, Dhansiri-31.

Northeast link: waterways connect Brahmaputra basin with Bangladesh & mainland logistics grid under PM Gati Shakti.

Quick Facts for MCQs

Legal & Policy

  • Acts: IWAI 1985, National Waterways 2016, Inland Vessels 2021, Jetties/Terminals Regulations 2025 streamline governance.
  • Scheme: Jalvahak 2024 offers 35 % cost reimbursement to shift freight from road/rail to waterways.
  • Budget 2025-26 extends tonnage-tax to IWT, attracting private capital.

Growth & Targets

  • Expansion: operational NW length rose 2,716 km (2014) to 4,894 km (2023).
  • Goal 2030: raise freight share 2 %→5 %, surpass 200 MMT cargo.
  • Vision 2047: Maritime Amrit Kaal aims 500 MMT inland water traffic.

Bottlenecks

  • Navigability: seasonal depth loss, heavy siltation necessitate costly dredging, hamper year-round traffic.
  • Infrastructure: scarce jetties, poor multimodal links, limited finance keep waterborne trade at 3.5 % share.
  • Connectivity: weak first-last mile access nudges industries toward road/rail alternatives.

4.Hiroshima and Nagasaki Bombings (World War II)

Hindustan Times
Illustration for Hiroshima and Nagasaki Bombings (World War II)

What & Where

Atomic bombings = first wartime nuclear strikes by USA on Hiroshima (Honshu) and Nagasaki (Kyushu), August 1945.

Weapons: Little Boy (uranium gun-type) & Fat Man (plutonium implosion) from secret Manhattan Project (1942-45).

Targets picked for military-industrial hubs, clear blast assessment, and to deter planned Allied land invasion.

Quick Facts for MCQs

Military Strategy

  • Objective: Force unconditional surrender; avoid protracted amphibious assault after brutal Okinawa casualty lessons.
  • Selection: Targets spared earlier firebombing to gauge pure atomic impact; Kokura skipped due to cloud cover.
  • Timing: Dual strikes within 72 hours intended to signal repeatable capability and urgency.

Geopolitical Dimension

  • Deterrence: Demonstrated U.S. power as Cold War opening move; message to USSR amid Asia power vacuum.
  • Soviet entry accelerated U.S. schedule; fear of partitioned Japan mirrored earlier German precedent.
  • Post-1945, nuclear monopoly lasted until USSR test (1949), igniting global arms race and NPT debates.

Human Cost

  • Radiation: Acute sickness, leukemia spikes, genetic effects documented by ABCC and later RERF studies.
  • Infrastructure: Over 60% of Hiroshima buildings destroyed; Nagasaki’s Urakami valley obliterated.
  • Ethics debate: Civilian targeting questioned under just-war principles; spurred modern IHL refinements.

Technological Milestone

  • Nuclear physics: Proved controlled fission deliverable via aircraft; catalysed reactor, medical isotope, energy research.
  • Security doctrine: Introduced Mutually Assured Destruction, second-strike capability, and constant alert postures.
  • Governance: Prompted UN Atomic Energy Commission (1946) and later IAEA (1957) for oversight.

5.Quit India Movement Commemoration (Quit India)

Indian Express

What & Where

Mass uprising seeking immediate British withdrawal, launched 8 Aug 1942 by Gandhi during AICC session, Bombay

Venue Gowalia Tank Maidan (August Kranti Maidan); slogan “Quit India” and call “Do or Die” galvanised nation

Movement spread nationwide; temporary parallel governments in Ballia, Tamluk, Satara displayed de-facto self-rule

Quick Facts for MCQs

Precipitating Factors

  • WWII entry without consultation, Burma fall and invasion fears intensified demand for British exit
  • Cripps Mission March 1942 offered post-war dominion; Gandhi called it “post-dated cheque”, sparking outrage
  • Famine fears from wartime rice exports and economic exploitation sharpened mass resentment

Participation & Methods

  • Leaderless phase saw students, youth conduct strikes, sabotage rail and telegraph lines across urban centres
  • Strategy officially non-violent; Gandhi allowed self-defence, causing sporadic attacks on colonial property
  • Muslim League non-participation underscored growing communal divide and demand for separate state

Outcomes

  • British authority collapsed temporarily; Ballia, Tamluk, Satara instituted parallel governments for days to weeks
  • Harsh repression involved mass detentions, censorship, collective fines yet failed to restore full legitimacy
  • Movement’s psychological impact convinced British establishment independence was inevitable, paving for 1947 power transfer

Key Personalities

  • Gandhi’s Do-or-Die mantra launched; Aruna Asaf Ali unfurled Tricolour at Gowalia Tank amid police crackdown
  • Socialist Yusuf Meherally coined Quit India and earlier Simon Go Back slogans, shaping agitational messaging

8.Great Barrier Reef Coral Bleaching (Coral Bleaching)

IT
Illustration for Great Barrier Reef Coral Bleaching (Coral Bleaching)

What & Where

Coral bleaching = stress-expulsion of zooxanthellae algae from coral tissue, leaving white, energy-starved skeleton

Great Barrier Reef, Coral Sea off northeast Australia, world’s largest reef (~2 300 km), now at 40-yr record cover loss

Bleaching reversibility possible if stress brief; prolonged stress leads to coral mortality and reef ecosystem collapse

Quick Facts for MCQs

Causes & Triggers

  • Temperature spike; climate change and El Niño amplify sea-surface heat
  • Pollution runoff; nutrients fuel algal blooms lowering water quality
  • Solar irradiance, extreme low tides, occasional cold snaps add stress layers

Bleaching Sequence

  • Symbiosis; algae photosynthesise, feed and colour coral
  • Stress signal; coral physiology disturbed, oxidative damage rises
  • Algae expulsion; tissue transparent, white skeleton visible, disease risk high

Impacts

  • Ecosystem loss; nursery and feeding grounds vanish, biodiversity plummets
  • Economic hit; reef tourism, coastal fisheries revenues shrink, shoreline erosion rises
  • Carbon role; dead reefs store less carbon, weaken natural wave barriers

Key Data Points

Illustration for Biochar Potential in India (Biochar Technology)

What & Where

Definition: Biochar = porous, carbon-rich solid from pyrolysis of agri-residue or organic municipal waste in low-/no-oxygen.

Process sites: Decentralised village units, stubble-burning belts (Punjab), municipal waste hubs in urban India.

Application spread: Soil additive, concrete filler, syngas/bio-oil energy, decentralised wastewater adsorbent.

Quick Facts for MCQs

Energy & Byproducts

  • Syngas: powers rural micro-grids, delivers diesel-free 8–13 TWh yearly.
  • Bio-oil: could offset 8 % national diesel/kerosene, trimming 2 % fossil emissions.
  • Coal-equivalent replacement: 0.4–0.7 MT, easing import dependence.

Agriculture Impact

  • Water-holding rise improves semi-arid yields by up to 25 %.
  • Fertiliser need dips 10–20 %, lowering input costs and runoff.
  • Andhra Pradesh natural-farming pilots report higher soil organic carbon with on-farm biochar.

Construction Use

  • Concrete blend 2–5 % biochar increases heat resistance 20 %; IIT-Madras confirms mechanical strength gain.
  • Each m³ biochar-concrete locks ~115 kg CO₂, lowering embodied carbon.
  • Offers low-carbon material option for India’s $1 trn infrastructure push.

Implementation Gaps

  • Market: No uniform biomass pricing; feedstock procurement risky.
  • MRV: Weak carbon accounting deters international credit buyers.
  • Policy: Biochar absent from mainstream agri, energy, waste frameworks.

Policy Prescriptions

  • Integration: Add biochar to Crop Residue schemes, SAPCCs, bio-energy policies.
  • Incentive: Tag biochar as eligible removal tech under upcoming Indian Carbon Market.
  • R&D: Develop zone-specific pyrolysis standards; promote low-cost indigenous units.
