Subject: Environment & Ecology (Biodiversity Heritage Sites (BHS), Wetland Conservation, Crop Wild Relatives, Biological Diversity Act, 2002)
Why in News?
The Borjuli Wetland in Sonitpur district, Assam, has been notified as a Biodiversity Heritage Site (BHS) for conserving the wild rice species Oryza rufipogon, an invaluable genetic resource for developing climate-resilient rice varieties. The recognition was granted under the In-situ Conservation and Management of Wild Rice project being implemented since 2022.
About Borjuli Wetland
Significance
UPSC Prelims Analysis
Biodiversity Heritage Sites are a high-probability UPSC topic. Aspirants should remember that they are notified under Section 37 of the Biological Diversity Act, 2002 by the State Government, in consultation with local bodies, to conserve ecologically significant areas while permitting compatible community practices. Borjuli is significant for protecting Oryza rufipogon, the wild ancestor of cultivated rice, making it crucial for food security and climate-resilient agriculture. UPSC may ask about the difference between Biodiversity Heritage Sites and Protected Areas, the implementing agencies, or the importance of crop wild relatives in agricultural biodiversity.

Why in News?
The Chhattisgarh Government has advised farmers to adopt the Direct Seeded Rice (DSR) method during the 2026 Kharif season to address possible rainfall uncertainty associated with El Niño and promote water-efficient agriculture. Simultaneously, several states, including Punjab, are expanding DSR cultivation to conserve groundwater and reduce cultivation costs.
About Direct Seeded Rice (DSR)
Advantages
Challenges
UPSC Prelims Analysis
DSR is a high-probability agriculture topic due to its role in addressing groundwater depletion, labour shortages, and climate change. Aspirants should distinguish DSR from Puddled Transplanted Rice (PTR)—PTR requires nursery raising, transplanting, and continuous flooding, whereas DSR involves direct sowing with significantly lower water and labour requirements. UPSC may ask about types of DSR, advantages and limitations, or its role in climate-resilient agriculture, water-use efficiency, and greenhouse gas mitigation. The topic also links with sustainable agriculture, resource conservation technologies, and food security.

Why in News?
The Giant African Snail has spread rapidly across Tirunavaya Panchayat in Malappuram district, Kerala, entering school campuses and raising concerns over children’s health and agricultural damage. The invasive species is proliferating during the monsoon due to favourable warm and humid conditions.

Key Characteristics
Health & Ecological Impact
UPSC Prelims Analysis
Invasive alien species are a recurring UPSC Prelims theme. Aspirants should remember that the Giant African Snail is not native to India and is listed among the IUCN’s 100 Worst Invasive Alien Species. Its ability to reproduce rapidly, consume hundreds of plant species, and transmit the rat lungworm parasite makes it significant from both ecological and public health perspectives. UPSC may ask about its scientific name, invasive status, reservoir of disease, ecological impacts, or compare it with other invasive species such as Water Hyacinth, Lantana camara, Prosopis juliflora, and African Catfish.

Subject: Environment & Ecology / Science & Technology (Marine Biodiversity, Deep-Sea Ecosystems, Taxonomy, ICAR Institutions, Arabian Sea)
Why in News?
Scientists at the ICAR–Central Marine Fisheries Research Institute (ICAR-CMFRI), Kochi, have discovered a new deep-sea fish species, Cyttopsis indica, commonly called the Indian dory, from the Arabian Sea. The discovery corrected a long-standing taxonomic misidentification through morphological and DNA analyses, enriching India’s documented marine biodiversity.
About Cyttopsis indica
About ICAR-CMFRI
UPSC Prelims Analysis
Marine biodiversity is an emerging UPSC theme, especially discoveries of new species. Aspirants should remember that Cyttopsis indica is a deep-sea fish discovered in the eastern Lakshadweep Sea, not a freshwater or coastal species. UPSC may ask about the discovering institution (ICAR-CMFRI), the role of DNA barcoding in taxonomy, or distinguish between the Arabian Sea, Lakshadweep Sea, and continental slope. The topic also links with India’s Exclusive Economic Zone (EEZ), deep-sea exploration, and marine conservation.

Subject: Environment & Ecology / Science & Technology (Wildlife Conservation, Animal Tracking Techniques, Biodiversity Monitoring, Radio Telemetry)
Why in News?
Radio telemetry came into focus after the death of the radio-tagged White-rumped Vulture (Z25) due to electrocution in the Nilgiris. Data from its radio transmitter had earlier enabled conservationists to repeatedly rescue and monitor the bird, highlighting the importance of telemetry in wildlife conservation.
About Radio Telemetry
Components of a Radio Telemetry System
Applications
UPSC Prelims Analysis
Wildlife monitoring techniques are increasingly important for UPSC. Aspirants should distinguish radio telemetry from GPS/satellite telemetry. Conventional VHF radio telemetry requires researchers to manually track signals using a receiver, whereas GPS or satellite telemetry automatically records and often transmits location data over long distances. UPSC may ask about the components of a radio telemetry system, its applications in wildlife conservation, or compare it with other tracking technologies. The topic also links with species conservation programmes involving tigers, elephants, vultures, snow leopards, and migratory birds.

Why in News?
The Securities and Exchange Board of India (SEBI) reported an encouraging response to Specialised Investment Funds (SIFs). As of 31 May 2026, SIFs had accumulated over ₹13,500 crore in Assets Under Management (AUM) across 56,000+ investor folios, reflecting growing demand for sophisticated investment products.
About Specialised Investment Funds (SIFs)
Key Features
UPSC Prelims Analysis
Financial market reforms are an important UPSC theme. Aspirants should remember that SIFs are neither Mutual Funds nor PMS, but a new investment category positioned between the two. Unlike PMS, which requires a minimum investment of ₹50 lakh, SIFs require only ₹10 lakh while offering greater portfolio flexibility than conventional mutual funds. UPSC may ask about the regulator (SEBI), minimum investment threshold, permitted investment strategies, or distinguish SIFs from Alternative Investment Funds (AIFs) and PMS. The topic also links with capital market deepening, investor protection, and financial sector reforms.

Why in News?
The Ministry of Rural Development released a PIB Backgrounder highlighting the LokOS Platform as the digital backbone of the Deendayal Antyodaya Yojana–National Rural Livelihoods Mission (DAY–NRLM).

Coverage (2026)
UPSC Prelims Analysis
LokOS is an important example of Digital Public Infrastructure (DPI) in rural governance. Aspirants should remember that it is not a banking or payment platform, but a digital management system for SHGs and Community-Based Organisations under DAY–NRLM. UPSC may ask about its implementing ministry, implementing agency (Digital India Corporation), objectives, and linkage with SHE-LEAPS and the Lakhpati Didi Mission. The topic also connects with financial inclusion, rural livelihoods, women-led development, and e-governance initiatives.
