Delhi-NCR's ₹9,585-crore PARIVARTAN scheme to scrap old polluting trucks and buses, a CAQM drone-surveillance order against stubble burning, a new damselfly species boosting Kerala's odonate count to 192, and a Nyishi-tribe fish-conservation effort in Arunachal Pradesh.
July 2026 — At a Glance
Beyond the Western Ghats Eco-Sensitive Area notification, CAFE-III fuel norms and the hydrogen train already covered in this month's Science digest, July 2026 carried a genuinely separate stream of environment news. Delhi-NCR's ₹9,585-crore PARIVARTAN scheme got its operational guidelines, aiming to scrap around 2 lakh old polluting trucks and buses. Ahead of the paddy-harvest season, the Commission for Air Quality Management (CAQM) directed four states to deploy drones against stubble burning. In the Western Ghats, a spread-winged damselfly named Lestes paloti became the first new species of its genus recorded from the region in 96 years. And in Arunachal Pradesh, the Sangno clan of the Nyishi tribe launched a community-led effort to save a threatened Himalayan fish from a predatory rival.
1. PARIVARTAN — Phasing Out Delhi-NCR's Polluting Commercial Fleet
The scheme
- What & why — PARIVARTAN (Programme for Accelerated Renewal and Incentivization of Vehicle Assets for Reducing Transport Air Pollution and Network Emissions) is a Centre-supported scheme to replace old, polluting commercial vehicles in the National Capital Region (NCR) with cleaner alternatives; the Union Cabinet approved it in June 2026, and the Ministry of Housing and Urban Affairs issued operational guidelines.
- Scale & target — Targets BS-IV and older commercial vehicles; expected to benefit around 2.07 lakh truck and bus owners across Delhi-NCR; total financial outlay of ₹9,585 crore, with the Centre contributing ₹5,041 crore.
Incentives & requirements
- Replacement rules — All replacement Light Goods Vehicles (LGVs) must be electric; bus operations are limited to BS-VI CNG or electric vehicles — owners scrapping BS-IV-or-older LGVs for new electric LGVs get a 100% motor-vehicle tax exemption for 10 years, a 100% registration-fee waiver, an 8% OEM discount and a 5% interest subvention.
- Building on earlier policy — PARIVARTAN complements the Vehicle Scrappage Policy, 2021 and the Delhi EV Policy, 2026, and is managed end-to-end through a dedicated digital portal run by the Ministry of Road Transport and Highways to ensure transparency.
2. CAQM's Drone Watch on Stubble Burning
The directive
- What was ordered — Ahead of the paddy-harvest season, the Commission for Air Quality Management (CAQM) directed Punjab, Haryana, Uttar Pradesh and Rajasthan to strengthen preparedness by adopting drone-based surveillance for effective monitoring and prevention of stubble-burning incidents, seeking an action-taken report by 14 August 2026.
- A broader real-time platform — CAQM also called for a real-time data platform combining satellite imagery, drones and ground sensors for continuous tracking of stubble-burning incidents, and issued a statutory direction for the complete elimination of paddy-stubble burning in 2026 across Punjab, Haryana and NCR districts of Uttar Pradesh.
About the CAQM
- The body — The Commission for Air Quality Management in NCR and Adjoining Areas is a statutory body established by a 2021 Act of Parliament, replacing the earlier Environment Pollution (Prevention and Control) Authority (EPCA), to coordinate air-quality action across Delhi and its neighbouring states.
3. Lestes Paloti — A New Damselfly for the Western Ghats
The discovery
- Where & who — The new spread-winged damselfly was found on the laterite plateaus behind Sir Syed College, Taliparamba (Kannur district, Kerala); zoology teacher Vinayan Nair first identified the specimen, with the study led by Dr Maya George, Dr Abraham Samuel and Dr Kalesh Sadasivan, published in the *International Journal of Odonatology*.
- Distribution & habit — Recorded across six Kerala districts — Kannur, Kozhikode, Wayanad, Malappuram, Palakkad and Ernakulam. Unlike related damselflies that stay close to open water, Lestes paloti inhabits scrub vegetation on laterite hillocks, often found well away from visible water bodies.
Why it matters
- A 96-year gap — This is the first new species of the genus Lestes recorded from the Western Ghats in about 96 years — the previous one, *Lestes malabaricus*, was described in 1929 — and the first new Lestes species recorded from India since 1987.
- Naming & Kerala's odonate count — The species is named 'Lestes paloti' in honour of Dr Muhammed Jafer Palot of the Zoological Survey of India (ZSI), Kozhikode, recognising his contributions to documenting Western Ghats fauna; the discovery raises Kerala's total odonate (dragonfly and damselfly) count to 192 species.
4. Community Conservation — Saving the Himalayan Ray-Finned Fish
The species & the threat
- About the fish — The Himalayan ray-finned fish (*Schizothorax pelzami*, also called the Transcaspian marinka, locally 'Ngarsing' in the Nyishi language) is a carp/minnow-family (Cyprinidae) species that thrives in clean, well-oxygenated, snow-fed glacial streams — such as the Lapabung and Richaso streams in East Kameng district, Arunachal Pradesh; it is listed as IUCN Endangered.
- The threat — The species faces heavy predation from the mahseer ('tiger of the water'), a prized sport fish that now shares its habitat and preys on smaller native fish, threatening the marinka's local survival.
The conservation effort
- The translocation — The Sangno clan of the Nyishi tribe translocated 52 fingerlings of *Schizothorax pelzami* from the Lapabung stream at Talo village to a mahseer-free stretch of the Richaso stream at Weshi village, giving the threatened species a predator-free refuge.
- A proposed fishing ban — A 5-year blanket fishing ban on the Richaso stream has been proposed to protect the translocated population, continuing the Nyishi community's tradition of using temporary fishing bans to protect fish stocks while preserving traditional livelihoods and eco-tourism potential.
