Building Upwards, Not Outwards: The Case for Vertical Industrial Parks
(ECONOMICS) (DD) West Bengal’s Finance Minister has pitched vertical industrial parks as an answer to the State’s acute shortage of industrial land, proposing multi-storey hubs for the gems and jewellery sector to revive it and stem the exodus of skilled artisans.
A vertical industrial park stacks manufacturing, warehousing, logistics and allied services on different floors of one complex. It trades horizontal sprawl for height — much like a multi-storey office tower, but for light industry.
What suits a vertical park
| Suitable | Less suitable |
| Electronics, precision engineering, assembly, garments, gems and jewellery | Steel, cement, chemicals and other heavy or land-intensive industries |
| High-value, low-weight goods | Bulky raw materials and heavy machinery |
| Units needing shared services such as design, testing, customs clearance and security | Units with large effluent, vibration or hazard footprints |
Why the idea is gaining ground
- Land-use efficiency: More output per acre in dense urban and peri-urban belts where industrial land is scarce and costly — a long-standing bottleneck for industrial corridors.
- Shared infrastructure: Common utilities, warehousing, testing labs, waste handling and logistics cut costs for small firms.
- Clustering: Manufacturers, suppliers and service providers under one roof strengthen supply-chain links — the logic of industrial complexes.
- Urban integration: Brings jobs closer to where workers live, with worker housing possible within the same complex.
Land scarcity ➜ Multi-storey design ➜ Shared utilities and services ➜ Industrial clustering ➜ Jobs near cities
Challenges
- Logistics: Moving raw materials, machinery and finished goods between floors needs heavy freight lifts and loading bays.
- High upfront cost: Specialised structural design, fire safety and material-handling systems raise capital costs.
- Regulatory coordination: Urban planners, industrial development bodies, pollution-control boards and local governments must align on norms such as floor-area ratio and safety.

Roads That Grow Forests: India’s Green Highways Push
(ECONOMICS) (PIB) More than 3.61 crore saplings have been planted across about 1.32 lakh km of National Highways over the past five years (as of July 2026), as India blends tree cover, recycled materials and satellite monitoring into highway building.
The National Highway network has grown by nearly 61% — from 91,287 km in 2014 to 1,46,572 km by March 2026. Green highways aim to ensure that this expansion of road transport does not come at the cost of the environment.
The policy backbone
The Green Highways (Plantation, Transplantation, Beautification and Maintenance) Policy, 2015 provides the framework. Its objectives include:
- Reducing air pollution and dust, as trees act as natural sinks for pollutants.
- Arresting soil erosion on embankment slopes and moderating wind and incoming radiation.
- Providing shade, cutting noise and headlight glare.
- Creating employment for local people — plantation is undertaken by Self-Help Groups, private agencies, State Forest Departments, Forest Corporations and contractors, monitored by a Plantation Cell.
Key initiatives
| Initiative | What it does |
| NHAI plantation norms (September 2026) | Provisional completion only if at least 80% of the Right of Way (RoW) earmarked for plantation is covered, with a minimum 90% sapling survival rate |
| National Highways Green Cover Index (NH-GCI) | First annual report (2025–26), prepared with ISRO’s National Remote Sensing Centre; assesses green cover within RoW on nearly 30,000 km across 24 States |
| Miyawaki plantations | Dense native forests on small land parcels; plants can grow up to 10 times faster (see conservation strategies) |
| Bio-bitumen | Developed by CSIR-CRRI and CSIR-IIP from rice-straw pyrolysis; a 100-metre trial stretch laid on the Jorabat–Shillong Expressway (NH-40), Meghalaya |
| Green National Highway Corridors Project | 781 km in Himachal Pradesh, Rajasthan, Uttar Pradesh and Andhra Pradesh, with a US$ 500 million World Bank loan |
| Green Highways Excellence Awards | Instituted by NHAI in 2025; 2026 awards weight plantation survival, native species and diversity |
Why bio-bitumen matters: India imports nearly half its bitumen. Turning crop residue into a road binder cuts imports and offers an alternative to stubble burning.
Rice straw ➜ Pyrolysis to bio-oil ➜ Blending with bitumen ➜ Greener roads, less stubble burning

Rabi MSP 2027-28: Big Push for Oilseeds and Pulses, Token Rise for Wheat
(ECONOMICS) (PIB) The Cabinet Committee on Economic Affairs (CCEA) has approved higher Minimum Support Prices (MSP) for all six mandated rabi crops for Rabi Marketing Season (RMS) 2027-28.
The new prices (₹ per quintal)
| Crop | MSP 2027-28 | MSP 2026-27 | Increase | Cost of production | Margin over cost |
| Wheat | 2,610 | 2,585 | 25 | 1,264 | 106% |
| Barley | 2,286 | 2,150 | 136 | 1,447 | 58% |
| Gram | 5,958 | 5,875 | 83 | 3,751 | 59% |
| Lentil (masur) | 7,390 | 7,000 | 390 | 3,854 | 92% |
| Rapeseed and mustard | 6,613 | 6,200 | 413 | 3,367 | 96% |
| Safflower | 7,215 | 6,540 | 675 | 4,810 | 50% |
Reading the numbers
- Biggest gainers: Safflower (+₹675), rapeseed-mustard (+₹413) and lentil (+₹390) — signalling a deliberate tilt towards oilseeds and pulses to cut India’s dependence on edible-oil and pulse imports.
- Wheat: A rise of just ₹25 (about 0.97%), yet it still enjoys the highest margin over cost (106%).
- The 1.5x rule: All prices are at least 1.5 times the all-India weighted average cost of production, a principle announced in the Union Budget 2018-19.
- Procurement scale: Wheat procurement rose to 3,715 lakh metric tonnes during 2014-15 to 2025-26, against 2,254 LMT in 2004-05 to 2013-14.
How MSP is fixed
CACP recommendation ➜ Views of States and Ministries ➜ CCEA approval ➜ Announcement before sowing ➜ Procurement by FCI and State agencies
MSP has no statutory backing; it is an administrative price. Effective procurement, mainly through the Food Corporation of India, is concentrated in wheat and rice, so pulses and oilseeds depend on schemes such as PM-AASHA and missions like NMEO–Oilseeds.

Threads from a Poison Plant: Reviving the Aak Fibre Craft of the Thar
(ENVIRONMENT) (DTE) Kabbu Devi of Aati village in Barmer (Rajasthan) has been honoured by the State government for weaving a muffler from bhambhuriya — the silk-like floss of the aak plant — drawing attention to a desert craft that is struggling to survive.
Know the plant
| Feature | Details |
| Scientific name | Calotropis gigantea (crown flower); a large shrub up to about 4 m tall |
| Distribution | Dry, semi-arid and sandy regions of Asia and Africa; in India, mainly Rajasthan, Gujarat, Uttar Pradesh and Madhya Pradesh |
| Features | Waxy white or lavender flowers; milky latex containing toxic cardiac glycosides; drought-hardy |
| Lifespan | Five to seven years; flowers and fruits within a year |
From bark and floss to products
- Bark fibre: Spun into thread for ropes, dari (flat-woven rugs) and charpoys.
- Seed floss (bhambhuriya): Light, silk-like fibre used in quilts and pillows.
- Medicinal use: Used in Ayurveda (as Arka) and Siddha for ailments such as skin disorders and cough.
Dry the branches ➜ Strip the bark ➜ Soak in buttermilk ➜ Twist and beat ➜ Spin on a dheri
The Maru Meghwal community and farmers of western Rajasthan have kept this skill alive for generations, spinning threads in three thicknesses — akodi, beodi and teodi. Today both the craft and aak cultivation face neglect, though rising demand for natural fibres and traditional crafts could revive desert livelihoods.

From Ledgers to the Cloud: The Bankers’ Books Evidence Act, 2026
(ECONOMICS) (NOA) The Bankers’ Books Evidence Act, 2026 came into force on 1 October 2026, replacing the Bankers’ Books Evidence Act, 1891. It received the President’s assent on 13 August 2026.
The law decides when a bank’s records can be produced in court as evidence. Certified copies of entries in “bankers’ books” are accepted as prima facie evidence, so banks need not bring original registers to court.
Old law versus new law
| Aspect | Act of 1891 | Act of 2026 |
| Records covered | Physical ledgers and registers | Physical, electronic, digital, virtual and cloud-based records — a technology-neutral approach |
| Admissibility | Built for paper books | Electronic or digital records expressly admissible, valid and enforceable as evidence, with integrity safeguards |
| Certification | Non-uniform certificates | Standardised certification through manual, digital or electronic signatures |
Why it matters
- Matches modern banking: Core banking, mobile and cloud systems now hold most records (see Digital Payment Infrastructure of India).
- Faster dispute resolution: Recovery suits, fraud cases and insolvency proceedings can rely on certified electronic records.
- Ease of doing business: Less paperwork and fewer summons for bank officials.
Electronic bank record ➜ Integrity safeguards ➜ Standardised certificate ➜ Prima facie evidence in court

Listening to Hydrogen: CHIME Maps the Universe’s Ancient Glow
(SCIENCE AND TECHNOLOGY) (PIB) The Canadian Hydrogen Intensity Mapping Experiment (CHIME) has made its first standalone detection of the glow of hydrogen from when the Universe was about five billion years old. The collaboration includes researchers from India’s Raman Research Institute (RRI), an autonomous institute of DST.
The science in brief
- The 21-cm line: Neutral hydrogen atoms emit radio waves at about 1,420 MHz (21 cm) when the electron’s spin flips relative to the proton’s.
- Intensity mapping: Instead of cataloguing galaxies one by one, CHIME measures the combined glow of hydrogen over large regions — faster, cheaper and deeper in time.
- Standalone result: Earlier, CHIME had to cross-correlate its data with optical galaxy surveys; this detection uses only its own data, from 94 nights of observation in 2019.
- Finding: Roughly two per cent of the Universe’s hydrogen was in neutral atomic form at that epoch.
Neutral hydrogen ➜ 21-cm radio emission ➜ Intensity mapping by CHIME ➜ Expansion history ➜ Test of dark energy
The telescope
| Feature | Details |
| Location | Dominion Radio Astrophysical Observatory, British Columbia, Canada |
| Design | Four 100 m × 20 m cylindrical reflectors with 1,024 dual-polarisation receivers; no moving parts — it scans the sky as the Earth turns |
| Band | 400–800 MHz |
| Other use | A prolific detector of fast radio bursts (FRBs) |
Why it matters: mapping hydrogen across cosmic time reveals how fast the Universe has expanded, helping to test theories of dark energy — the force thought to accelerate cosmic expansion after the Big Bang.

UNICORN: India and Japan’s First Defence Co-development Project
(INTERNATIONAL RELATIONS) (TH) Japan has urged India to fast-track internal processing of the agreement on the Unified Complex Radio Antenna (UNICORN), signed during Japanese Prime Minister Sanae Takaichi’s visit to India in July 2026.
What is UNICORN?
- A stealthy integrated mast that combines communication, electronic-warfare, identification and navigation antennas into a single structure under a radome.
- Fewer exposed antennas mean a smaller radar cross-section; the optimised arrangement also limits mutual interference between systems.
- Developed in Japan by NEC, Sampa Kogyo and Yokohama Rubber; it equips the Japan Maritime Self-Defense Force’s Mogami-class frigates.
- Bharat Electronics Limited (BEL) is the Indian partner for producing the masts for Indian Navy warships.
Milestones
Talks begin (2022) ➜ Memorandum of Implementation, Tokyo (Nov 2024) ➜ Co-development agreement (July 2026) ➜ Masts for Indian Navy warships
Why it matters
- It is the first co-development of defence equipment between the two countries — moving India–Japan relations beyond exercises towards joint technology.
- Supports Atmanirbhar Bharat in naval electronics and boosts the stealth of future warships (see Naval Defence).
- Strengthens the Special Strategic and Global Partnership and Indo-Pacific maritime cooperation.

XY Chromosomes, Female Body: Understanding Swyer Syndrome
(SCIENCE AND TECHNOLOGY) (TH) Swyer syndrome has been in the news, prompting a closer look at this rare condition of sex development in which a person with XY chromosomes develops female reproductive structures.
Key facts
| Feature | Details |
| Also called | 46,XY complete gonadal dysgenesis |
| Chromosomes | 46,XY — the pattern usually found in males |
| Body | Female external genitalia; usually a uterus and fallopian tubes |
| Gonads | Non-functional “streak gonads”, usually removed surgically because of a high cancer risk |
| Frequency | About 1 in 80,000 people |
| Causes | Often unknown; SRY gene variants in about 15% of cases and MAP3K1 variants in up to 18% |
How sex development normally proceeds
Y chromosome ➜ SRY gene ➜ SRY protein ➜ Testis development ➜ Male-typical structures
If the SRY protein is missing or faulty, the fetus does not form testes and develops along a female-typical path despite having a Y chromosome. The basics of sex chromosomes are covered in Heredity.
Management
- Often recognised when puberty does not begin as expected.
- Hormone therapy starts puberty and protects bone health; the chromosome pattern itself cannot be changed.
- Those with a uterus may carry a pregnancy with a donated egg or embryo.
