TKDL — India-Brazil Cooperation to Block Biopiracy
India’s CSIR (Council of Scientific and Industrial Research) and Brazil’s INPI (National Institute of Industrial Property) signed a cooperation arrangement on the Traditional Knowledge Digital Library (TKDL), aiming to prevent wrongful patents on India’s traditional medical knowledge before international patent offices.
About TKDL: Established in 2001 by CSIR and the Ministry of AYUSH, TKDL digitises and catalogues India’s traditional knowledge — primarily from Ayurveda, Unani, Siddha, Sowa Rigpa, and Yoga — in five international languages (English, German, French, Japanese, Spanish), making it accessible to patent examiners worldwide as prior art.
Why it matters: Before TKDL, companies filed patents on traditional Indian remedies — the turmeric wound-healing patent (US, 1997) and basmati rice patent (US, 1997) were landmark cases that India had to fight. TKDL makes patent examiners aware that these “inventions” are centuries-old Indian knowledge.
UPSC angle: Biopiracy, CBD (Convention on Biological Diversity), Nagoya Protocol (Access and Benefit Sharing), TRIPS Agreement flexibilities, traditional knowledge protection under IPR.
Lenacapavir — Zimbabwe’s HIV Prevention Milestone
Zimbabwe launched the nationwide rollout of Lenacapavir (brand: Yeztugo), developed by Gilead Sciences — the world’s first twice-yearly injectable PrEP (pre-exposure prophylaxis) for HIV prevention.
- Mechanism: Capsid inhibitor — blocks the HIV capsid protein that the virus uses to replicate
- Effectiveness: ~99.9% prevention of HIV transmission (PURPOSE 1 and 2 clinical trials)
- Advantage over daily oral PrEP: A six-month injection vs. daily pill — dramatically improves adherence
- WHO prequalification: Approved for rollout in high-burden countries
Zimbabwe has one of the world’s highest HIV prevalence rates (~11.9%). The rollout targets women and girls aged 16–25 — the most at-risk group in sub-Saharan Africa.
UPSC angle: Global health equity, WHO role, PEPFAR, TRIPS waiver for HIV medicines, India’s generic drug manufacturing (CIPLA, Sun Pharma have generic versions in pipeline), SDG 3 (Good Health).
Contarinia icardiflores — New Blossom Midge Discovered
Scientists at ICAR-DFRI (ICAR-Directorate of Floricultural Research), Pune, discovered a new blossom midge species — Contarinia icardiflores (family Cecidomyiidae) — whose larvae attack flower buds, causing significant yield losses in horticultural crops including marigold, chrysanthemum, and jasmine.
The species is named in honour of the institute’s contributions to floricultural research.
UPSC angle: Biodiversity, insect taxonomy, ICAR research institutions, floriculture sector (worth ~₹15,000 crore in India; major export earner — cut flowers, essential oils), pest management.
National Mission on Natural Farming — Update
The National Mission on Natural Farming (NMNF), launched as a centrally sponsored scheme (approved in 2023 Union Budget), crossed 12 lakh hectares of land converted to natural farming practices across 15+ states. Andhra Pradesh leads with its ZBNF (Zero Budget Natural Farming) model under the RySS (Rythu Sadhikara Samstha).
UPSC angle: Natural farming vs. organic farming (difference), chemical input reduction, soil health, carbon sequestration, ZBNF founder Subhash Palekar, SDG 2 (Zero Hunger), PM Pranam scheme (promoting alternative fertilisers).
