Kerala's amendment to Wildlife Protection Act sparks federal debate over 'vermin' declaration powers

The Kerala government has introduced the Wild Life Protection (Kerala Amendment) Bill 2025, seeking to devolve powers from the Union to the State regarding wildlife management. The Bill aims to allow the State to declare Schedule II animals, such as wild boars, as 'vermin' to address severe human-wildlife conflict. It also empowers the Chief Wildlife Warden to order the killing or capture of animals that have injured humans. However, critics argue this move challenges federal structures as Wildlife is on the Concurrent List, and any state law repugnant to the Central Act requires Presidential assent.

  • Wildlife is a subject under the Concurrent List of the Indian Constitution.
  • Section 62 of the Central Wildlife (Protection) Act 1972 currently reserves the power to declare 'vermin' for the Union government.
  • The amendment seeks to address a 'lived crisis' of human-wildlife conflict in Kerala's agricultural and forest buffer zones.

Establishment of Southeast Asia’s First Coral Larvae Cryobank to Protect Threatened Reef Ecosystems

The University of the Philippines Marine Science Institute has established Southeast Asia’s first coral larvae cryobank. This facility freezes coral larvae at ultra-low temperatures (-196°C) to preserve genetic diversity against threats like climate change, ocean warming, and pollution. The project is part of a regional initiative across the 'Coral Triangle,' which houses 76% of the world's coral species. Cryopreservation acts as a 'genetic insurance policy,' allowing scientists to revive and outplant corals to restore damaged reefs. This breakthrough method ensures genetic material can be stored for years and used to help restore reefs lost to bleaching.

  • The Coral Triangle is known as the 'Amazon of the seas,' covering 5.7 million sq. km across six countries.
  • Coral reefs are highly vulnerable, with 70-90% predicted to be lost if global warming exceeds 1.5°C.
  • Cryopreservation involves using vitrification to prevent ice crystal formation that would otherwise destroy the larvae.

India Faces Health and Environmental Crisis Due to Improper E-waste Recycling

India is the third-largest e-waste generator globally, producing 2.2 million tonnes in 2025. A majority of this is processed in the informal sector using crude methods like acid baths and open-air burning. This releases toxic substances like lead, cadmium, and mercury, causing severe health issues including respiratory diseases, neurological damage, and DNA damage. Children in recycling clusters are particularly vulnerable, showing high levels of lead in their blood. While the E-Waste (Management) Rules, 2022, introduced Extended Producer Responsibility (EPR), implementation remains weak, and the informal sector still handles 95% of the waste.

  • India generates 2.2 million tonnes of e-waste annually, with only 43% officially processed as of 2023-24.
  • Informal recycling releases persistent organic pollutants (POPs) and heavy metals into the environment.

India Needs Better Forecasting and Infrastructure to Manage Extreme Monsoon Events

India received 8% more monsoon rain than normal this year, leading to bountiful kharif crops but also causing significant disasters. Torrential rains in August and September inundated districts in Himachal Pradesh, Punjab, and Jammu and Kashmir. The editorial argues that while forecasting has improved, the 'framing' of these events needs to change. Terms like 'cloudburst' are often misused by officials to describe deluges, potentially masking failures in disaster preparedness. The India Meteorological Department (IMD) had predicted 'above normal' rainfall, yet infrastructure remains inadequate to handle the resulting floods, landslides, and siltation.

  • India's monsoon rainfall was 8% above the long-period average of 87 cm this year.
  • Improved forecasting must be matched by better disaster preparedness and resilient infrastructure.
  • Misuse of meteorological terms like 'cloudburst' can shift blame from governance failures to 'natural' calamities.

Informal sector dominance and regulatory gaps hinder formal e-waste recycling in India

Despite government efforts to promote formal e-waste recycling through the Extended Producer Responsibility (EPR) framework, the informal sector continues to play a dominant role. Millions of tons of electronics are disposed of annually, but only about one-third is processed through proper channels. The informal sector often harvests components for repair rather than recycling, which disrupts the 'circular economy' and leads to environmental hazards. Policymakers face a dilemma as informal set-ups provide livelihoods but lack the technology for safe metal extraction. Strengthening the EPR framework and improving material traceability are essential to secure critical minerals like lithium and cobalt.

  • India generated approximately 4.17 million metric tonnes of e-waste in 2022, but only a third is processed formally.
  • The Extended Producer Responsibility (EPR) framework requires manufacturers to collect and recycle their end-of-life products.
  • Informal recyclers often prioritize component harvesting for repairs over the extraction of precious metals.
