Pre & Mains Notes


1. Nepal Flash Floods: Hundreds Missing, Indian Nationals Affected

WHAT HAPPENED
Flash floods in Nepal’s Rasuwa district killed over 150 people, with hundreds still missing, including more than 100 Indians.

CORE ISSUE
Extreme rainfall and ice-rock avalanches triggered sudden flooding, highlighting the vulnerability of Himalayan regions to cascading disasters.

KEY DETAILS
Indian nationals affected: Over 100 Indians were among those reported missing; many were travelling towards Kailash Mansarovar.
Multiple districts hit: At least five districts were affected, including Rasuwa, where flash floods damaged settlements and infrastructure.
Possible trigger: Scientists suggested an ice-rock avalanche may have triggered a surge in the border river, though assessment was preliminary.
India’s response: PM Modi spoke with Nepal’s PM and offered assistance; India also dispatched relief material, while additional NDRF teams were deployed in Uttar Pradesh and Bihar.

WHY IT MATTERS
Shows the growing disaster vulnerability of the Himalayan region and the need for stronger cross-border disaster preparedness, early-warning systems and regional cooperation.

Pre & Mains Notes


1. Salmonella Infections: Beyond Typhoid & Diarrhoea

WHAT HAPPENED
Experts highlight that Salmonella infections are broader than typhoid, with non-typhoidal Salmonella often causing undiagnosed gastroenteritis and sometimes severe bloodstream infections.

CORE ISSUE
India needs stronger surveillance and a One Health approach to address Salmonella transmission and rising antimicrobial resistance.

KEY DETAILS
Two major groups: S. Typhi and S. Paratyphi cause typhoid/paratyphoid, while non-typhoidal Salmonella (NTS) commonly causes gastroenteritis.
Transmission: NTS has a wider animal–environment–human cycle; poultry, eggs, meat and other animal-derived foods can act as sources.
AMR threat: Drug-resistant Salmonella is increasing; resistance to fluoroquinolones in S. Typhi reached 85% in 2015–19 in the cited study.
Way forward: Strengthen food safety, sanitation, surveillance and antimicrobial stewardship; use blood culture for suspected typhoid rather than relying solely on the Widal test.

WHY IT MATTERS
Salmonella demonstrates the One Health connection between humans, animals, food and the environment, while antimicrobial resistance threatens effective treatment.

GS Paper II: Health, Public Health, Disease Surveillance
GS Paper III: Science & Technology — Antimicrobial Resistance, One Health, Food Safety

Pre & Mains Notes


1. Praggnanandhaa Wins Grand Chess Tour Title

WHAT HAPPENED
R. Praggnanandhaa defeated Fabiano Caruana 15–13 in the Grand Chess Tour final in St Louis, becoming the first Indian to win the Grand Chess Tour title.

CORE ISSUE
India’s rising dominance in elite chess and Praggnanandhaa’s emergence as a leading global player.

KEY DETAILS
- Historic first: Praggnanandhaa became the first Indian to win the prestigious Grand Chess Tour, which combines Classical, Rapid and Blitz formats.
- Comeback: He overturned a 3–9 deficit against Caruana before winning the final 15–13.
- Indian chess strength: The article highlights the growing presence of Indian players, including D. Gukesh, R. Praggnanandhaa and R. Vaishali, at the highest level.
- Road to 2026: Praggnanandhaa had missed qualification for the 2026 Candidates but responded strongly, including defeating Magnus Carlsen twice in the same event.

WHY IT MATTERS
Reflects India’s growing prominence in global chess, with young Indian players increasingly challenging established international champions.

UPSC Relevance: Sports diplomacy, India’s soft power, youth development and global achievements.

2. FCNR(B) Deposits Push Forex Reserves to Record High


WHAT HAPPENED
India’s foreign exchange reserves rose to an all-time high of $729.33 billion in August, helped by strong inflows into FCNR(B) deposits.

CORE ISSUE
Higher forex reserves strengthen the RBI’s ability to defend the rupee against external shocks and capital outflows.

KEY DETAILS
- FCNR(B) window: RBI’s concessional swap facility encouraged NRIs to bring foreign-currency deposits into Indian banks; the scheme has been operational since June 8.
- Record reserves: Forex reserves increased to $729.33 billion, surpassing the previous high of $728.49 billion.
- Rupee support: Stronger reserves provide greater capacity to manage rupee volatility and external financing pressures.
- External resilience: Higher reserves improve India’s ability to withstand shocks such as oil-price spikes, capital outflows and global interest-rate changes.

WHY IT MATTERS
A strong reserve position acts as a buffer against external-sector shocks, supporting financial stability and confidence in the Indian economy.

GS Paper III: Indian Economy — Forex Reserves, Balance of Payments, Exchange Rate, External Sector.
