Updated: 14 October 2026 | Estimated reading time: 8 minutes
Three government updates published on 13 October deserve a place in competitive-exam revision this week: PM GatiShakti’s five-year progress report, a laboratory-developed filter for dye-contaminated wastewater, and new figures on India’s seaweed sector. The useful part is not just the headline. Each update carries measurable figures, an institution or scheme to remember, and a wider policy connection that may be tested in general awareness, economy, environment or science-and-technology sections.
This edition also separates current affairs from candidate-action notices. Recruitment, admit-card and result items are linked to their existing detailed guides instead of being repeated as short, competing posts.
At a glance: the figures to remember
| Update | Key figure or fact | Why it matters |
|---|---|---|
| PM GatiShakti | More than 1,800 data layers; 58 Central Ministries/Departments; all 36 States/UTs | Integrated infrastructure and logistics planning |
| Infrastructure appraisal | 421 projects worth about ₹20.23 lakh crore evaluated in 2026 | Coordination across transport modes and last-mile links |
| Wastewater filter | 98.6% methylene-blue and 96.7% Congo-red decolorisation in 120 minutes | Research combining nanomaterials, light, vibration and machine learning |
| Seaweed cultivation | 82,728 tonnes in 2025, compared with 18,890 tonnes in 2015 | Coastal livelihoods, value addition and the Blue Economy |
1. PM GatiShakti completes five years
The PM GatiShakti National Master Plan was launched by Prime Minister Narendra Modi in October 2021 to improve coordination in infrastructure planning. Its five-year progress report, released by the Ministry of Commerce and Industry on 13 October 2026, describes the programme as a geospatial planning ecosystem rather than merely a map-based portal. The platform combines information from different ministries and governments so that a road, rail line, port, industrial corridor or local service can be assessed alongside the networks it depends on.
The latest government figures report more than 1,800 data layers covering 58 Central Ministries and Departments and all 36 States and Union Territories. More than 65 software modules or tools and over 100 mobile and web applications have been integrated. The Network Planning Group had evaluated 421 infrastructure projects worth around ₹20.23 lakh crore by 2026. Those are project-evaluation figures; they should not be described as 421 completed projects or ₹20.23 lakh crore already spent.
The plan has also expanded into district-level and social-sector planning, including roads, schools, healthcare facilities and water pipelines. The government says the public platform’s Unified Geospatial Interface was launched in September 2025, while knowledge-management and decentralised data systems are intended to improve data sharing and monitoring. The Union Cabinet has also approved an Integrated Transport and Logistics Authority to strengthen long-term planning, appraisal and impact assessment.
Exam connection: remember the launch year, the role of BISAG-N in developing the geospatial platform, the Network Planning Group and the principle of multimodal connectivity. For a deeper explanation of the phased rollout and what the figures mean, read the PM GatiShakti five-year explainer.
2. A machine-learning-assisted material for dye-contaminated wastewater
The Department of Science and Technology’s Institute of Nano Science and Technology (INST), Mohali, reported a material designed to help treat wastewater containing persistent industrial dyes. The research combines zinc oxide (ZnO) nanoparticles with porous fibres made from biodegradable polylactic acid (PLA). The nanoparticles were synthesised using turmeric extract, where naturally occurring compounds acted as reducing and stabilising agents.
The design addresses a practical problem with loose nanoparticle catalysts: recovering them after treatment and preventing them from remaining in discharged water can be difficult. Immobilising ZnO in a porous nanofibre membrane creates a material that can be handled more easily. The researchers combined light-driven photocatalysis with mechanical excitation. The vibrations produce piezoelectric polarisation, which can reduce the loss of photo-generated electron–hole pairs and encourage reactive species involved in pollutant breakdown.
In the reported laboratory tests, the material achieved 98.6% decolorisation for methylene blue and 96.7% for Congo red within 120 minutes under combined light and ultrasonic excitation. The study also reported approximate inactivation of 75% of E. coli and 71% of S. aureus after six hours. Machine learning was used to model the relationship between experimental conditions—such as light intensity, time, dye concentration and ultrasonic frequency—and decolorisation behaviour.
These results are promising but need careful interpretation. Decolorisation is not automatically proof that every contaminant has been fully mineralised or that the resulting water meets drinking-water standards. The government release describes research potential, not a claim that a large industrial system is already operating at commercial scale. Read the science explainer on the ZnO–PLA wastewater filter for the mechanism and limits.
Exam connection: know the full forms of ZnO and PLA, the difference between photocatalysis and piezocatalysis, and why machine learning may help predict experimental performance without physically removing pollutants itself.
3. Seaweed farming: output, sites and livelihood support
A Department of Fisheries update on 13 October highlighted seaweed farming at Munnaikadu near Mandapam in Tamil Nadu and the contribution of women-led self-help groups. Fisheries Secretary Dr Abhilaksh Likhi met cultivators and reviewed ways to increase production, strengthen processing and improve market links. The announcement connects a local coastal activity with a larger economic objective: creating additional income for fishing communities while building reliable supplies for food, fertiliser, animal feed and other value-added uses.
India has a coastline of 11,099 kilometres, and research institutions have identified 384 suitable seaweed sites covering 24,707 hectares across coastal States and Union Territories. According to the release, national seaweed production rose from 18,890 tonnes in 2015 to 74,083 tonnes in 2024 and 82,728 tonnes in 2025. Under the Pradhan Mantri Matsya Sampada Yojana (PMMSY), projects worth ₹181.11 crore had been approved for seaweed development during 2020–27, including a Seaweed Park in Tamil Nadu. Financial assistance was reported for 37,255 cultivation rafts and 44,080 monoline units.
Production growth does not remove the need for good site selection, seed quality, ecological safeguards and buyers for the harvested crop. The government’s current emphasis includes decentralised seed banks, farmer training, entrepreneurship, offshore cultivation and value addition. The ICAR-Central Marine Fisheries Research Institute’s Mandapam Regional Centre has been designated a Centre of Excellence for seaweed development and research; Lakshadweep is a notified seaweed cluster.
Exam connection: link seaweed farming to the Blue Economy, coastal livelihoods, PMMSY, marine research institutions and Tamil Nadu’s role in the sector. The seaweed cultivation explainer separates production data from assistance and infrastructure counts.

Static GK and possible question areas
India’s capital is New Delhi, its currency is the Indian rupee, and the national executive is led by Prime Minister Narendra Modi; President Droupadi Murmu is the constitutional head of state. For these updates, prioritise the relationship between GatiShakti and logistics, the institutions behind geospatial mapping and marine research, the environmental application of nanomaterials, and the scheme supporting seaweed cultivation.
Possible question areas include: the year PM GatiShakti was launched; the role of BISAG-N and the Network Planning Group; the meanings of ZnO and PLA; the distinction between decolorisation and complete pollutant removal; India’s coastline length; the site and production figures for seaweed; and the objective of PMMSY. These are revision prompts, not a substitute for checking the underlying notifications and reports.
