Place in the news

National Waterway-2 and Indo-Bangladesh Protocol Route

GS3 Infrastructure / Inland WaterwaysGS2 International RelationsPrelims and Mains

Why in news
A PIB backgrounder of 16 October 2026 describes India's push for safer inland navigation. It highlights the first riverine lighthouses on the Brahmaputra (National Waterway-2), hydrographic surveys and digital tools.
What it is
National Waterway-2 is the Brahmaputra stretch in Assam from Sadiya to Dhubri. It is the longest navigable stretch among Indian waterways and carries tea, coal and fertiliser cargo. It links to Bangladesh through the Indo-Bangladesh Protocol Route.
NW-2 length
NW-2 runs from Dhubri to Sadiya over 891 km of navigable length, the longest of any Indian waterway.
Least Available Depth
LAD is the minimum water depth available in a navigation channel for a stretch and period. It sets the permissible vessel draft and cargo capacity.
Digital platforms
PANI gives navigation and asset information on one portal. Naudarshika, the National River Traffic and Navigation System, was launched in 2025.
NW-2 stretch
NW-2 is the Brahmaputra from Sadiya to Dhubri, 891 km, declared a national waterway in 1988.
Cargo and destination
APCL methanol made at Namrup is bound for Pangaon Port in Bangladesh.
Enabling facilities
Customs and immigration complexes at Bogibeel and Dhubri made the shipment possible.
Protocol history
India and Bangladesh signed a river trade protocol in 1972.
Waterway cargo growth
Cargo on national waterways rose from 18 million tonnes in 2013-14 to 218 million tonnes in 2025-26.

Don’t confuse with NW-1 vs NW-2 vs NW-3: NW-1 is the Ganga-Bhagirathi-Hooghly system (Haldia to Prayagraj). NW-2 is the Brahmaputra (Sadiya to Dhubri). NW-3 is the West Coast Canal in Kerala (Kottapuram to Kollam).

Don’t confuse with IWAI vs DGLL: IWAI surveys and maintains aids on National Waterways. The Directorate General of Lighthouses and Lightships manages general aids to navigation along the coast.

Don’t confuse with NW-1 vs NW-2: NW-1 is the Ganga (Prayagraj to Haldia). NW-2 is the Brahmaputra (Sadiya to Dhubri).

Places in the news: 26 Prelims questions since 2013, rising (12% of news questions in 2022–26); they test location and why it matters.

No practice question for this one; the card may still help an answer. Why: Backgrounder with lasting facts on National Waterways, riverine lighthouses and cargo growth. Prelims asks about places and schemes, but no fresh debate or count supports a question here.

Worth revising until Prelims 2028: most news questions come within two years of the event.

Science and technology

Martian Analogue Sites

GS3 Science and TechnologyPrelims and Mains

Why in news
On 16 October 2026, the Ministry of Science & Technology reported that University of Kerala scientists identified two sulphate minerals in Tamil Nadu and Chile's Atacama Desert. These help establish the sites as Martian analogues.
What it is
A Martian analogue site is a place on Earth whose geology, chemistry or physical conditions resemble those of Mars. Scientists study such sites to interpret Martian minerals, past water activity and possible habitability. Orbital data alone cannot fully characterise Martian minerals, so ground-based work on analogues is needed.
Minerals found
Melanterite was identified at Neyveli, and gypsum at the Tiruchirappalli Badlands and the Atacama Desert. Both are hydrous sulphates that record water-rock interactions.
What each mineral shows
Gypsum preserves evidence of past aqueous environments, while melanterite indicates short-lived wet, acidic and oxidizing conditions.
Instrument used
A laser Raman spectrometer detected the spectral fingerprints of the minerals. It is supported by DST-FIST at the Department of Geology, University of Kerala.
Biosignature link
Gypsum can preserve biosignatures within its mineral matrix, which makes it useful for astrobiology.
Publication
The findings appeared as two papers in the Journal of Geophysical Research: Planets.
DST-FIST
Fund for Improvement of S&T Infrastructure (FIST) is a Department of Science and Technology programme that supports research infrastructure in universities and institutions.

Don’t confuse with Analogue site vs. mission: An analogue site is a place on Earth used to study Mars-like conditions. A mission sends a spacecraft to Mars itself.

Don’t confuse with Melanterite vs. gypsum: Melanterite is an iron sulphate that forms by sulphide oxidation. Gypsum is a calcium sulphate that records past water activity.

Science and technology: 57 Prelims questions since 2013; most test the concept behind the news, not the news itself. In Mains, 12 news-triggered questions.

No practice question for this one; the card may still help an answer. Why: Concept of analogue sites and minerals is syllabus-relevant. Science and tech makes up 17% of news-linked Prelims questions, but this research finding is a niche one.

Worth revising until Prelims 2028: most news questions come within two years of the event.

Report or index

PAIMANA Infrastructure Performance Dashboard

GS3 InfrastructurePrelims and Mains

Why in news
On 16 October 2026, MoSPI released the quarterly update of the PAIMANA Performance Dashboard, which now tracks 184 indicators after 21 were added.
What it is
PAIMANA (Project Assessment, Infrastructure Monitoring & Analytics for Nation-building) is a MoSPI digital dashboard. It tracks the performance of key infrastructure sub-sectors through standardised indicators on one public platform. It is meant to support evidence-based policymaking.
Publisher
The dashboard is run by the Ministry of Statistics and Programme Implementation (MoSPI), with data drawn from the line Ministries and Departments.
Launch date
The dashboard was launched on 16 April 2026.
Framework
Indicators follow five dimensions: Access, Quality, Fiscal Cost & Revenue, Utilization, and Affordability.

Don’t confuse with PAIMANA vs PM Gati Shakti: PAIMANA is a MoSPI dashboard that monitors infrastructure performance indicators. PM Gati Shakti is a national master plan platform for planning and coordinating infrastructure projects.

Reports and indices: 14 Prelims questions since 2013; they test who publishes a report and what it measures.

No practice question for this one; the card may still help an answer. Why: New MoSPI dashboard on infrastructure, 184 indicators. Reports and indices are 4% of news-linked Prelims questions; this is routine data, so no question.

Worth revising until Prelims 2028: most news questions come within two years of the event.

Scheme

Scheme of Assistance to National Sports Federations

GS2 Welfare schemesPrelims and Mains

Why in news
On 16 October 2026, the Ministry of Youth Affairs and Sports issued operational guidelines for the revised Scheme of Assistance to National Sports Federations, continued for 2026-27 to 2030-31 with an outlay of ₹7,386.74 crore.
What it is
The Scheme of Assistance to National Sports Federations is run by the Ministry of Youth Affairs and Sports. It funds federations to prepare athletes for the Olympics, Asian Games, Commonwealth Games, Paralympics and World Championships. It covers coaching camps, athlete support, foreign exposure, national championships and federation governance.
Period and outlay
The scheme continues for 2026-27 to 2030-31, the 16th Finance Commission cycle, with a total outlay of ₹7,386.74 crore.
Olympic Training Centres
Single-sport centres with modern sports science facilities are planned, to reduce reliance on overseas training.
National Games support
Assistance of up to Rs 50 crore is provided for conducting National Games, covering equipment, Timing, Scoring and Result services, technical officials' remuneration and technical conduct.
Indigenous sports outreach
Support to NSFs of indigenous games to seek demonstration-event status in global competitions and set up federations abroad.
Multilateral and Global South cooperation
Funding is provided for sports events and meetings organised for bodies such as BRICS and BIMSTEC.

Don’t confuse with NSF scheme vs Khelo India: The NSF scheme funds federations for elite preparation and events. Khelo India is a separate scheme for grassroots talent and sports infrastructure.

Schemes: 52 Prelims questions since 2013, 10 in Prelims 2026 alone. They test features, the period and who funds it. In Mains, 33 news-triggered questions, mostly GS3.

No practice question for this one; the card may still help an answer. Why: Scheme continued for 2026-27 to 2030-31 with Rs 7,386.74 crore outlay. Schemes are 16% of Prelims, but sports schemes are rarely asked.

Worth revising until Prelims 2028: most news questions come within two years of the event.

Environment

Commission for Air Quality Management (CAQM)

GS3 Environment / PollutionGS2 Statutory bodiesPrelims and Mains

Why in news
On 16 October 2026, CAQM extended the requirement for PTZ cameras with live video feeds to all industries covered under Statutory Direction No. 98 in NCR. The new Order supersedes its Order of 5 October 2026.
What it is
CAQM is the statutory body for air quality management in the NCR and adjoining areas, set up under a 2021 law. It replaced the EPCA and can issue binding directions. GRAP is the Graded Response Action Plan, a set of stage-wise emergency measures that CAQM's Sub-Committee triggers as air quality worsens.
Trigger
The Sub-Committee on GRAP reviewed air quality and IMD/IITM forecasts on 6 November 2026 before invoking Stage-III.
AQI data source
The daily AQI bulletin of the CPCB put Delhi at 382, in the 'Very Poor' category.
Cumulative stages
Stage-III actions apply in addition to Stage-I and Stage-II actions already in force.
Implementing agencies
Pollution Control Boards of NCR States and the DPCC must ensure strict implementation of all three stages.
Legal basis
CAQM was set up under the Commission for Air Quality Management in National Capital Region and Adjoining Areas Act, 2021, and replaced the EPCA.
PAVAN full form
PAVAN stands for Platform for Air quality Vigilance and Analytics for NCR. It is the name of CAQM's Integrated Command and Control Centre (I3C).
Data integrated
The platform uses over 30 APIs and data streams, including air quality, emissions, weather, satellite, camera, mobility, complaint and compliance data.
Working principle
The centre works on 'Detect, Analyse, Act'. Deviations from norms or Statutory Directions trigger alerts and escalation to the concerned agency.
States covered
The State Action Plan module covers Delhi, Haryana, Punjab, Rajasthan and Uttar Pradesh.
Industries covered
The order covers all 17 highly polluting categories identified by CPCB, Red Category medium and large air-polluting industries, food and textile units with boilers or thermic fluid heaters, and metal units with furnaces.
Camera placement
Cameras must cover fuel-feeding points, gas meters, stack emissions and OCEMS sampling ports, and fume extraction areas where applicable.
Live feed
Video must stream continuously in real time using RTSP to the servers or portals of CPCB, the SPCBs and DPCC.
Enforcement
The State Governments of Haryana, Uttar Pradesh and Rajasthan and the GNCTD, with CPCB and the SPCBs/DPCC, must ensure implementation.
State split
Punjab has 18 districts and Haryana has 16 districts covered.
Reporting
Squads report the ground situation and steps taken to the CAQM Cell daily. The cell is at SAS Nagar.
Predecessor
CAQM replaced the Supreme Court-appointed Environment Pollution (Prevention and Control) Authority (EPCA) for the NCR.
Revised GRAP size
The revised GRAP has 48 actions: 25 in Stage-I, 8 in Stage-II, 10 in Stage-III and 5 in Stage-IV.
Shift of actions to Stage-I
Actions on DG sets and entry of BS-IV and below buses moved from Stage-II to Stage-I.
Sonipat added
Restrictions on older LMVs (BS-III petrol, BS-IV diesel) now extend to Sonipat, along with the existing HVD districts.
C&D portal monitoring
The web-portal monitoring of dust control at C&D sites extends to eligible projects beyond municipal limits; the 500 sq m plot threshold is unchanged.
Technical Members
The ACC approved two full-time Technical Members for three years or until age 70, whichever is earlier.
Direction
Statutory Direction No. 98 sets a uniform PM emission limit of 50 mg/Nm³ for identified industries in Delhi-NCR.
Basis
The standard rests on CPCB recommendations, IIT Kanpur studies and a CPCB Technical Committee.
Timelines
Large and medium industries must comply from 1 August 2026; the remaining industries from 1 October 2026.
Who implements
NCR State Governments, the Delhi Government, the Pollution Control Boards of Haryana, Uttar Pradesh and Rajasthan, and the Delhi Pollution Control Committee must implement it.
Main pollutant
PM2.5 is the dominant pollutant affecting Delhi's AQI. Both local emissions and transboundary movement across the airshed matter.
Direction on stubble
Direction No. 96 of 13.02.2026 mandates time-bound implementation of State Action Plans to end wheat stubble burning in 2026.
States addressed
The Direction is addressed to Punjab, Haryana and Uttar Pradesh. Delhi (GNCTD) and Rajasthan are only advised to make efforts.
Fire count, April-May 2025
Fire events recorded in the wheat season were 10207 in Punjab, 1832 in Haryana and 259 in the NCR districts of Uttar Pradesh. The standard protocol was developed by ISRO/IARI.
Parali Protection Force
States must set up a dedicated Parali Protection Force at district or block level to monitor and guard against open burning.
Support for small farmers
CRM machines must be available rent-free to small and marginal farmers through Custom Hiring Centres (CHCs).
Who invoked Stage-IV
The Sub-Committee on GRAP of CAQM took the decision at an urgent evening meeting.
Stage-IV trigger
Stage-IV is the 'Severe+' category, with Delhi's AQI above 450. It was invoked proactively, before that level was reached, and applies on top of Stages I-III.
Stage-III band
Stage-III of GRAP is for 'Severe' air quality (AQI 401-450). It was invoked early, as a proactive measure, while the AQI was still 'Very Poor'.
Legal basis of CAQM
CAQM is a statutory body created under the Commission for Air Quality Management in National Capital Region and Adjoining Areas Act, 2021, replacing EPCA.

Don’t confuse with CAQM vs EPCA: EPCA was the earlier body set up under the Environment (Protection) Act, 1986 on Supreme Court direction. CAQM is a statutory commission under its own 2021 Act and replaced EPCA.

Don’t confuse with CAQM vs CPCB: CPCB publishes the AQI bulletin and monitors air quality nationally. CAQM issues binding directions for the NCR and adjoining areas.

Don’t confuse with CPCB vs SPCB/DPCC: CPCB is the central pollution control body. SPCBs and DPCC are state and Delhi bodies that monitor compliance locally.

Don’t confuse with CAAQMS vs manual stations: CAAQMS are continuous ambient air quality monitoring stations giving real-time data. Manual stations sample periodically.

Don’t confuse with In-situ vs ex-situ management: In-situ management treats residue in the field itself. Ex-situ management removes the straw for other uses such as fodder or fuel.

Don’t confuse with GRAP Stage-III vs Stage-IV: Stage-III applies to 'Severe' (AQI 401-450). Stage-IV is for 'Severe+' (AQI above 450).

Environment: Prelims tests bodies, programmes and the law behind them; Mains asks why plans fall short.
