A depression over the Southwest Bay of Bengal has intensified into a deep depression and is likely to further intensify into Cyclone Fengal.
The system is currently close to an area with higher sea surface temperatures (SST), contributing to its potential intensification into a cyclonic storm.
Origin of the Name ‘Fengal’
The name ‘Fengal’ was proposed by Saudi Arabia and is rooted in Arabic.
It reflects a combination of linguistic tradition and cultural identity.
Cyclone Naming Process:
Cyclones in the North Indian Ocean are named by the World Meteorological Organization (WMO) and the United Nations Economic and Social Commission for Asia and the Pacific (UNESCAP) panel.
This panel includes 13 member countries, such as India, Bangladesh, Sri Lanka, and Pakistan, among others.
Each member country submits a list of potential cyclone names, and these names are used sequentially as cyclones form in the region.
This system, in place since 2004, ensures easy identification and effective communication of storms to the public.

Over 170 countries will meet in Busan, South Korea, starting for the fifth and final round of negotiations on a legally binding global treaty to combat plastic and marine pollution by 2024.
Why is a Global Plastic Treaty required?
Massive Increase in Plastic Production: Global plastic production has rapidly increased from 234 million tonnes in 2000 to 460 million tonnes in 2019, with expectations to reach 700 million tonnes by 2040. Asia is the largest producer, contributing nearly half of global plastic production.
Environmental and Health Impact: Plastic takes 20 to 500 years to decompose, and less than 10% is recycled. Around 400 million tonnes of plastic waste are generated annually, which is expected to rise by 62% by 2050. Much of this waste enters rivers and oceans, breaking down into microplastics that harm marine and terrestrial ecosystems.
Human Health Risks: Chemicals in plastics can disrupt hormones and cause diseases like cancer, diabetes, reproductive disorders, and neurodevelopmental impairments.
Contribution to Climate Change: Plastic production generates 3.6% of global greenhouse gas emissions, with most emissions coming from the production process, which relies on fossil fuels.
Global Plastic Pollution: India contributes significantly to global plastic pollution, accounting for 20% of the world’s total plastic waste, with emissions of 9.3 million tonnes.
What is on the Negotiating table?
Comprehensive Global Rules: The primary goal is to develop a legally binding global treaty to address plastic pollution throughout its life cycle, including its production from fossil fuels, waste management, and disposal.
Production and Waste Management Caps: Countries are debating the introduction of production caps, which have been opposed by oil-rich and plastic-producing nations, including India.
Types of Plastic and Chemical Additives: Discussions are ongoing regarding banning specific types of plastic, plastic products, and harmful chemical additives used in their production.
Recycling and Content Targets: The treaty might include legally binding targets for recycling and recycled content in consumer goods.
Just Transition for Affected Communities: There will be talks on supporting workers and communities whose livelihoods depend on plastic production and industries, ensuring a fair transition.
Financial and Technical Assistance: A key agenda item is how to mobilize private and public funding to meet the treaty’s goals, especially for developing countries.
What is India’s position?
India does not support caps on plastic production, arguing that such measures go beyond the scope of the UNEA resolutionadopted in 2022. India insists that the treaty must include provisions for financial and technical support, including technology transfer for developing countries.
India maintains that decisions regarding harmful chemicals in plastic production should be based on scientific studies and that regulation should be handled at the National level.
India has banned 19 categories of single-use plastics domestically but insists that decisions on banning other plastic products should be “pragmatic” and consider national circumstances.
India advocates for the establishment of a mechanism to assess the infrastructure needs and financial resources required for safe and scientific waste management.
It also emphasizes the need for adequate, timely, and predictable financial resources to support waste management and other treaty objectives.
Way forward:
Global Collaboration with National Flexibility: The treaty should foster global collaboration on plastic pollution while allowing flexibility for countries to implement solutions based on their unique socio-economic contexts and developmental priorities.
Enhanced Financial and Technological Support: Developed countries must provide financial and technological assistance to developing nations to ensure equitable implementation of the treaty’s provisions, especially for waste management infrastructure and transitioning away from plastic reliance.

Why in the News?
At the end of COP 29 in Baku (Azerbaijan), India will push for ambitious climate mitigation financing from developed nations. At the same time, India is at a critical juncture in its environmental and public health journey.
What are the current gaps in India’s environmental health regulations?
Fragmented Regulatory Framework: Current environmental governance is divided among multiple ministries, such as the Ministryof Environment, Forest and Climate Change (MoEFCC) and the Ministry of Health and Family Welfare (MoHFW).
This fragmentation results in a disconnect between environmental monitoring and health impact assessments, leading to ineffective responses to pollution-related health issues.
Outdated Legislation: Many existing laws, such as the Water (Prevention and Control of Pollution) Act, 1974, and the Air (Prevention and Control of Pollution) Act, 1981, have not been updated to reflect current environmental challenges.
They do not adequately address modern pollution sources or incorporate contemporary scientific understanding of environmental health risks.
Insufficient Data Collection and Research: There is a lack of reliable, comprehensive data on the health impacts of environmental pollutants.
While organizations like the Indian Council of Medical Research (ICMR) conduct important research, there is no centralized body to synthesize this data into actionable policies. This gap hampers effective regulation and public health interventions.
Inadequate Enforcement Mechanisms: Although laws exist to regulate pollution, enforcement remains weak due to bureaucratic inertia, lack of resources, and sometimes political influence.
Compliance with pollution control measures is often not monitored effectively, allowing violations to persist without consequences.
Exemptions in New Regulations: Recent proposals, such as the Remediation of Contaminated Sites Rules, 2024, have notable exemptions that exclude certain types of contaminated sites from regulation (e.g., radioactive sites, abandoned mines).
This can leave significant areas unaddressed in terms of cleanup and remediation efforts
How would a dedicated environmental health regulatory agency improve public health outcomes?
Integrated Approach: The agency would combine environmental and public health oversight, ensuring that regulations address the interconnectedness of environmental factors and health outcomes.
Enhanced Regulation and Enforcement: It would enforce stricter regulations on pollutants and ensure compliance from industries, reducing harmful exposures to air and water quality issues.
Data Collection and Research: The agency would prioritize systematic data collection on environmental health impacts, leading to better-informed policies and timely interventions for pollution-related health issues.
Public Awareness and Education: By educating the public about environmental health risks, the agency would empower communities to advocate for cleaner environments and healthier living conditions.
What international best practices can India adopt for an effective framework?
Implementation of EHS Guidelines: India can utilize the World Bank Group’s EHS Guidelines, which provide comprehensive standards for managing environmental health risks across various industries.
Framework for Environmental Public Health Functions: India can implement the EEPHF framework developed by the Pan American Health Organization (PAHO), which outlines responsibilities for health actors and governance structures necessary for effective environmental health management.
Comprehensive Risk Management: Implementing a structured risk management framework similar to that outlined by the U.S. Environmental Protection Agency (EPA) would allow India to evaluate multiple contaminants and exposure pathways comprehensively.
Environmental Health Incident Management: India can adopt a coordinated incident management framework like the Australia’s system, which provides mechanisms for responding to environmental health incidents effectively. This includes preparedness measures, effective communication strategies, and collaboration across government sectors to minimize impacts on public health.
Way Forward: To improve environmental health in India, there is a need for an integrated regulatory approach that updates laws, enhances enforcement, engages communities, and ensures comprehensive monitoring of pollutants.

The Central Pollution Control Board (CPCB)recorded an average AQI of 494 (Severe plus category) for Delhi where the different scales and methods explain the gap.
The Central Pollution Control Board (CPCB)recorded an average AQI of 494 (Severe plus category) for Delhi where the different scales and methods explain the gap.
A study by the Centre for Science and Environment reveals that:
Vehicular emissions are the largest contributor to Delhi’s air pollution, accounting for 51.5% of the city’s pollution;
Neighbouring districts add 34.97 %,
Farm fires contribute 8.19%, and
Dust particles make up 3.7 % of the total air pollution in the city.
What is the AQI Crisis in North India and What is the role of Climatic Conditions?
Northern India, particularly Delhi, is currently facing a severe air quality crisis, characterized by record-breaking Air Quality Index (AQI) levels. The AQI in many areas has exceeded 500, categorizing it as “severe-plus,” which poses significant health risks and limits visibility due to thick smog.
This year, despite a relatively pollution-free October and early November, the second week of November brought a sudden spike in toxic particulate matter, primarily PM2.5.
Weather Patterns: Inversions and stagnant air conditions have contributed to the accumulation of pollutants. The presence of a thick pollution blanket at around 500 meters above ground level has been linked to adverse local impacts when combined with regional emissions from stubble burning and other sources.
External Pollution Sources: The increase in pollution levels due to significant contributions from external sources, including emissions from nearby states like Punjab and Haryana.
What are the challenges in Monitoring AQI?
Inconsistent Data Reporting: There is confusion regarding AQI readings, with some private agencies reporting values exceeding 1,000 while official figures cap at 500. This discrepancy arises from differences in how pollutant concentrations are converted to AQI values based on less stringent national guidelines compared to WHO standards.
Dependence on External Data: India’s reliance on satellite data from NASA for monitoring fires and pollution limits its ability to independently assess air quality. There is a need for more localized monitoring using Indian satellites that can provide continuous coverage.
Lack of Comprehensive Frameworks: Current monitoring systems do not adequately account for regional cooperation or comprehensive frameworks that address transboundary pollution issues effectively. This lack of coordination complicates efforts to manage air quality across state lines.
Why does India need a sustainable and health-centric framework?
Long-Term Strategies: Efforts must go beyond immediate fixes and focus on sustainable practices that consider the interconnectedness of air quality management and climate change adaptation. This includes integrating scientific research into policy-making and resource allocation.
Public Health Prioritization: A health-centric approach should prioritize the well-being of citizens by implementing measures that reduce exposure to harmful pollutants, particularly for vulnerable populations such as children and the elderly.
Multidisciplinary Solutions: Addressing air quality issues necessitates collaboration across various sectors, including transportation, urban planning, and public health. This multidisciplinary approach can foster innovative solutions tailored to local contexts while addressing broader climatic challenges.
Conclusion: Northern India’s AQI crisis highlights the urgent need for sustainable, health-centric air quality management. The government should address the pollution through multidisciplinary solutions aligned with SDG 3 (Good Health) and SDG 13 (Climate Action), ensuring healthier lives and climate-resilient communities for future generations.
