Great Indian Bustard Recovery Programme

GS3 Environment and biodiversityPrelims and Mains

Why in news
On 4 October 2026, Union Environment Minister Bhupender Yadav released two captive-bred male Great Indian Bustards into the wild at Sam, Desert National Park, Jaisalmer.
What it is
The Great Indian Bustard is a large, ground-nesting bird of dry grasslands, found mainly in Rajasthan and Gujarat, and is critically endangered. The Bustard Recovery Programme rebuilds a viable population through conservation breeding, habitat restoration and egg 'jumpstart'. The bird is the State bird of Rajasthan.
Programme partners
The programme is run by the Environment Ministry, Rajasthan Forest Department and Wildlife Institute of India, with technical help from the International Fund for Houbara Conservation.
Captive population
Sam and Ramdevra facilities hold 97 birds: 40 from wild-laid eggs and 57 captive-bred.
Jumpstart approach
Captive-laid eggs placed in wild nests were accepted by wild females; six chicks hatched in Rajasthan and two in Gujarat.
Legal status
The Great Indian Bustard is listed as Critically Endangered on the IUCN Red List and is in Schedule I of the Wildlife (Protection) Act, 1972.
Captive stock
Sam and Ramdevra facilities hold 97 birds: 40 from wild-laid eggs and 57 bred in captivity.
Fenced grasslands
About 200 sq km of fenced grassland enclosures in Desert National Park serve as prime breeding habitat.
Gujarat Action Plan
Prepared by the Wildlife Institute of India with the Gujarat Forest Department. It aims at a minimum viable population of over 30 birds and 200-500 sq. km. of safe, contiguous habitat.
Naliya restoration
About 11 sq. km. of grassland infested with invasive Prosopis juliflora has been restored, and the enclosure has 30 km of predator-proof fencing covering 15 sq. km.
Jump-start
Infertile eggs of wild females are replaced with viable eggs from captive breeding. The chick from the second such attempt survived beyond the first three months in the wild.
Soft Release Centre
A centre near Naliya will house and acclimatise captive-bred birds from Rajasthan before eventual release.
Conservation status
The GIB is listed Critically Endangered on the IUCN Red List and is in Schedule I of the Wildlife (Protection) Act, 1972.

Don’t confuse with Houbara bustard: A different bustard of West and Central Asia; the International Fund for Houbara Conservation only gives technical help here.

Don’t confuse with Lesser Florican: Another endangered Indian bustard, smaller and found in grasslands of Gujarat, Rajasthan and Madhya Pradesh; not the Great Indian Bustard.

Don’t confuse with Great Indian Bustard vs Houbara bustard: The GIB is a resident Indian grassland bird. The houbara is a different bustard, and the International Fund for Houbara Conservation only gives technical help here.

Don’t confuse with Lesser florican vs Great Indian Bustard: Both are bustards of grasslands and share Kachchh habitat, but the lesser florican is a much smaller bird.

Scheme

Pradhan Mantri Awas Yojana-Gramin

GS2 Welfare schemesGS3 InfrastructurePrelims and Mains

Why in news
On 4 October 2026, Union Minister Shivraj Singh Chouhan handed over the first instalment of 3 lakh PMAY-G 2.0 houses worth ₹3,600 crore to Andhra Pradesh at Burripalem, Guntur. He also laid the foundation of a 177-house 3D concrete-printed pilot project.
What it is
Pradhan Mantri Awas Yojana-Gramin (PMAY-G) is a Centrally sponsored scheme of the Ministry of Rural Development. It gives financial help to eligible rural households without a pucca house to build one. It replaced the earlier Indira Awaas Yojana in 2016, and a second phase (2.0) is now under way.
Handover
First instalment of 3 lakh houses worth ₹3,600 crore was handed over to Andhra Pradesh under PMAY-G 2.0 at Burripalem village, Guntur district.
3D printing pilot
The country's first pilot housing project using 3D concrete printing has 177 houses and costs ₹14 crore.
Allocation raised
Andhra Pradesh was first deemed eligible for 76,000 houses; the Centre raised this to 3 lakh after the Chief Minister's request.
Construction time
The 3D-printed houses are expected to be completed within six months.
Implementing ministry
PMAY-G is run by the Ministry of Rural Development as a Centrally sponsored scheme, with costs shared between Centre and states.
Predecessor
PMAY-G replaced Indira Awaas Yojana from April 2016.
Target and progress
The target is 4.95 crore houses. Approvals for 3.91 crore have been given and over 3.05 crore are complete.
Women's ownership
Nearly 75 per cent of sanctioned houses are in the name of women or in joint ownership.
Convergence
Houses are linked with amenities such as roads, electricity, drinking water, LPG connections and toilets through convergence with other schemes.
Start date
The scheme has been implemented since 1 April 2016.
Minimum house size
Houses must be at least 25 sq. m., with a dedicated area for hygienic cooking.
Inspections and audits
Block officers inspect about 10% of houses and district officers 2% at each stage. Each Gram Panchayat holds a social audit at least once a year.
Toilet support through convergence
Beneficiaries get Rs 12,000 for a toilet from SBM(G), the employment scheme or another dedicated source.
IT platform
AwaasSoft is the web-based MIS that covers beneficiary identification, sanction, fund release and monitoring.

Don’t confuse with PMAY-G vs PMAY-Urban: PMAY-G (Rural Development Ministry) serves rural households; PMAY-Urban (Housing and Urban Affairs Ministry) serves urban poor.

Don’t confuse with PMAY-G vs Indira Awaas Yojana: IAY was the older rural housing scheme; PMAY-G replaced it in 2016.

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.

National Supercomputing Mission

GS3 Science and TechnologyPrelims and Mains

Why in news
On 4 October 2026, PIB published a explainer on India's supercomputing ecosystem under the National Supercomputing Mission: 40 systems, 68 PF as of September 2026.
What it is
The National Supercomputing Mission (NSM) was launched in 2015 to build a network of supercomputers in Indian academic and research institutions. It follows a 'Build approach' to create indigenous capability in servers, software, networking and cooling. It is steered by DST and MeitY and implemented by C-DAC and IISc.
Who steers and implements
DST and MeitY jointly steer the Mission. C-DAC Pune and IISc Bengaluru implement it.
Build approach
Three concurrent phases: assembly, manufacturing, and design and manufacturing support.
Planned capacity
NSM plans 50 supercomputers with cumulative capacity above 123 PF.
Indigenous servers
Rudra servers were designed by C-DAC and used in PARAM Rudra supercomputers; 6,000 had been deployed as of September 2026.
Network backbone
The National Knowledge Network connects supercomputing facilities across institutions.

Don’t confuse with TeraFLOPS vs petaFLOPS vs exaFLOPS: Tera is 10^12, peta is 10^15, exa is 10^18 calculations per second.

Don’t confuse with PARAM Rudra vs PARAM Shavak: PARAM Rudra are full supercomputers built on Rudra servers; PARAM Shavak is a small desktop-style system for colleges.

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.
