Ghepan Lake Glacial Monitoring

ЁЯФ╣ Why in News & Recent Development

Learning from the devastation caused by the flood resulting from a glacial burst in Nepal, the Lahaul-Spiti district administration recently decided to further strengthen monitoring and precautionary measures regarding the Ghepan Glacial Lake in Himachal Pradesh.

ЁЯФ╣ Key Conceptual & Analytical Details

Ghepang Ghat glacial lake, locally known as Ghepan Lake, is a high-altitude glacial lake situated at 4,070 meters in the Lahaul region of Himachal Pradesh. It is uniquely fed by three hanging glaciers. Over the past three decades, rapid glacier melt has significantly expanded the lake, turning it into a severe Glacial Lake Outburst Flood (GLOF) risk for downstream communities due to climate change in the Western Himalaya.

ЁЯФ╣ Strategic Importance & Future Impact

Proactive installation of early warning systems and enhanced monitoring are critical to averting catastrophic downstream disasters, safeguarding human lives, and protecting fragile alpine ecosystems against accelerated climate-induced hazards.

Rotenone Application in Fisheries Management

ЁЯФ╣ Why in News & Recent Development

State biologists in Southcentral Alaska carried out a restoration project by treating an entire lake with rotenone, a plant-derived piscicide, to eradicate an invasive population of northern pike.

ЁЯФ╣ Key Conceptual & Analytical Details

Rotenone is a naturally occurring compound derived from the roots of tropical plants in the genera Derris, Lonchocarpus, or Tephrosia. Used as an insecticide, pesticide, and piscicide, it blocks oxygen uptake in fish gills at carefully calculated concentrations. The predatory Northern Pike (Esox lucius) is an invasive, aggressive freshwater fish native to circumpolar regions that devastates native fish stocks.

ЁЯФ╣ Strategic Importance & Future Impact

Biological restoration using targeted piscicides helps restore native aquatic biodiversity and controls ecological disruption caused by invasive species spreading outside their native northern ranges.

ЁЯФ╣ UP PCS / STATE PCS HIGH-YIELD VALUE ADDITION

  • Species: Northern Pike (Esox lucius)

Global Coral Reef Status & Coral Bleaching

ЁЯФ╣ Why in News & Recent Development

The seventh Status of Coral Reefs of the World report by the Global Coral Reef Monitoring Network (GCRMN) highlighted that coral bleaching events are accelerating and recovery periods have shortened dramatically.

ЁЯФ╣ Key Conceptual & Analytical Details

Coral bleaching occurs when marine invertebrate corals experience environmental stress from rising temperatures, pollution, or ocean acidification. Under stress, corals expel their symbiotic food-producing algae (zooxanthellae) that provide nutrients and bright colors, exposing their white calcium carbonate exoskeletons.

ЁЯФ╣ Strategic Importance & Future Impact

Accelerating coral bleaching threatens marine biodiversity, coastal protection, and fisheries. Urgent global climate action is necessary to halt marine warming and preserve reef ecosystems.

RPwD Act, 2016 and Post-18 Disability Support

ЁЯФ╣ Why in News & Recent Development

Nearly a decade after the enactment of the Rights of Persons with Disabilities (RPwD) Act, 2016, ground reports expose a critical policy blind spot: a severe systemic vacuum in post-adulthood institutional support for Persons with Disabilities (PwDs).

ЁЯФ╣ Key Conceptual & Analytical Details

While the RPwD Act mandates inclusion, accessibility, and 21 disability categories under Article 253, families face a massive support gap after age 18 and Class XII. This parental dependency creates an economic 'care penalty' where caregivers (predominantly mothers) suffer employment loss, financial stress, and mental health burnout due to a lack of assisted living, adult day-care, and respite care.

ЁЯФ╣ Strategic Importance & Future Impact

Transitioning from parent-dependent care to a life-cycle approach with robust community-based rehabilitation, UDID integration, and respite homes is essential to uphold dignity and rights under Article 21.
