Heat hotspots
Context
Peenya, Hennur, and Nagawara, identified as Bengaluru’s emerging heat hotspots in a baseline study by the C40 Cities Climate Leadership Group
- Areas are developing into “urban heat islands,” with temperatures reaching up to 4°C higher than other parts of the city due to dense construction and a severe lack of green cover.
- A study by the Centre for Study of Science, Technology and Policy, mapped a Heatwave Health Risk Index for Karnataka, categorises Bengaluru as a moderate-risk city, driven by factors such as declining green cover and high population density.
Targeted Interventions & Cooling Measures
The Greater Bengaluru Authority (GBA) is collaborating with C40 Cities to implement localized cooling strategies in these high-risk areas:
- Indira Canteen Cooling Centers: Plans are underway to repurpose Indira Canteens, Namma Clinics, and urban primary health centers (PHCs) into daytime cooling spaces during peak summer months.
- Hennur Bande Park: A former stone quarry in Ward 24 is being converted into a public park to increase tree cover and enable natural cooling via evapotranspiration.
- Vulnerable Groups: Interventions specifically target outdoor workers (labourers and traffic personnel), children, and the elderly, who are most exposed to prolonged heat stress.
Cyber Command Unit plans
Context
Karnataka Cyber Command Unit (CCU) is planning to set up a dedicated wing to crack down on the consumption and trade of Child Sexual Abuse Material (CSAM).
- Cyber command unit plans will provide leads, the new wing aims to investigate through local channels to more effectively identify accused individuals and book cases within the state.
- Previously, the Karnataka State Police primarily relied on alerts from the International Centre for Missing and Exploited Children (ICMEC) via their “cyber tipline.”
- Authorities noted that Child Sexual Abuse Material (CSAM) is often traded as a commodity:
- Material is frequently hidden behind paywalls.
- The unit will focus on the darknet, where extensive markets for such content exist.
- The wing will also target the producers of this material, including those using AI tools to generate abusive content.
Golden Hour Network
Context
Golden Hour Network launched in Bengaluru to improve trauma care
- Launched: March 2026 at HOSMAT Traumacon.
- Purpose: The network aims to address gaps in trauma care time, training, and integration, creating a structured, collaborative platform.
- Structure: It operates as a co-governed clinical and academic network designed to connect specialists for improved trauma response.
- Activities: The GHN will facilitate monthly clinical rounds, quarterly specialty discussions, and host an annual trauma conference.
- Timeline: The initiative plans to onboard senior alumni and begin official clinical engagements over the six months following its launch.
- The initiative reflects a “patient-first” approach to improving patient outcomes through faster and more efficient trauma care practices.
Lalbagh Botanical Garden
Context
GSI sets up expert panel to study tunnel impact on Bengaluru’s Lalbagh Botanical Garden
- Study was prompted by the state government’s proposal to build a six-lane, ~18-km underground tunnel road connecting Hebbal and Central Silk Board.
- Objective: To assess the potential impact of tunnelling on the Peninsular Gneissic Complex, a 3-billion-year-old national geological monument located within the garden.
- Timeline: The panel has been directed to submit its report within three weeks to the GSI Southern Region head.
- Composition: Led by senior official K V Maruthi, the committee includes engineering geology experts from Bengaluru, Chennai, and Hyderabad.
Primary Concerns
- Potential for rock fractures and instability in the ancient gneiss formation.
- Threats to underground aquifers that feed Lalbagh’s lake and sustain its rare plant species.
- The project requires approximately six acres of land temporarily and one acre permanently within the garden.
Background and Controversy
The GSI’s intervention follows a formal request made in October 2025 by Bangalore South MP L.S. Tejasvi Surya, who flagged the project as “ecologically and geologically indefensible” due to its proximity to the heritage site.
About Lalbagh Botanical Garden
- Location: Bengaluru
- It was originally built by Hyder Ali in 1760, during the Sultanate of Mysore.
- The garden was later managed under numerous British superintendents before Indian Independence.
- The Preservation Act, 1979 passed by the Government of Karnataka to preserve the uniqueness of the park is under the provision of Karnataka Government Park (Preservation) Act, 1975.
Lalbagh Botanical Garden
Context
New species of night frog discovered in Western Ghats
- Researchers along with frontline staff of the forest department have discovered 35th night frog that is endemic to the Western Ghats.
- It is a new species of nocturnal frog in the Kali Tiger Reserve of Karnataka’s Western Ghats.
Features
- The frog was first identified by its unique advertisement call, which resembles the sound of wood being chopped.
- Habitat Type: Humid, rain-drenched corridors and stream networks
- Historical context: An ancient lineage that originated on the Indian landmass roughly 70 to 80 million years ago.
- While it looks nearly identical to the Kumbara Night Frog, DNA analysis confirmed it is a genetically distinct lineage, with a divergence of over 5%.
Kali Tiger Reserve
- Location: Uttara Kannada district
- It is formerly Dandeli-Anshi Tiger Reserve
- Park is a habitat of Bengal tigers, black panthers and Indian elephants.
- Vegetation: Evergreen and Moist deciduous forest
- Water Sports: The Kali River is a popular destination for white-water rafting, kayaking, and coracle rides.
- Tourism : Shiroli Peak for panoramic forest views or Syntheri Rocks and Ulavi Caves.
Miyawaki Method
Context
Mysuru City Corporation (MCC) launched its third Miyawaki-style urban forest project at Saalumarada Thimmakka Park in Dattagalli.
- Initiative is part of the MCC’s “Namma Mysuru-Namma Koduge” project aimed at restoring the city’s green cover and combating climate change.
Miyawaki Method
- Developed by Japanese botanist Akira Miyawaki.
- Technique involves planting native trees and shrubs very densely.
Features
- Forests grow up to 10 times faster than traditional methods.
- These ecosystems become self-sustaining within 2–3 years.
- Miyawaki forests are roughly 30 times denser and can contain 100 times more biodiversity than conventional plantations
