India has set a target to achieve 100 GW of nuclear installed capacity by 2050 to meet its decarbonization goals. The Sustainable Harnessing and Advancement of Nuclear Energy for Transforming India (SHANTI) Bill, 2025, consolidates existing laws like the Atomic Energy Act, 1962. The Bill aims to streamline regulation and promote indigenous Pressurised Heavy Water Reactors (PHWRs). Nuclear energy is viewed as essential for providing 'baseload' power, which intermittent sources like solar and wind cannot provide. The strategy includes indigenous technology for the entire nuclear fuel cycle.
- The SHANTI Bill 2025 consolidates the Atomic Energy Act, 1962, and the Civil Liability for Nuclear Damage Act, 2010.
- India aims for 100 GW of nuclear capacity by mid-century to achieve a high Human Development Index (HDI).
- Nuclear power provides necessary baseload capacity that is not dependent on weather or time of day.
Northern India is facing its annual cycle of severe air pollution and dense fog, leading to accidents and health crises. While fog itself doesn't increase toxicity, it traps residual emissions and reduces visibility, causing fatal road accidents and flight cancellations. In Delhi, the Air Quality Index (AQI) frequently enters the 'severe+' category (400+), triggering emergency restrictions under GRAP-4. These include bans on construction and shifting schools online. The editorial argues that the Commission for Air Quality Management (CAQM) must move beyond reactive 'meetings' and implement year-round strategies to keep AQI below 350 regardless of weather conditions.
- Fog exacerbates the pollution crisis by trapping moisture and residual emissions close to the ground.
- The Graded Response Action Plan (GRAP-4) is the highest level of emergency restriction for air pollution in Delhi.
- Poor visibility due to fog has led to significant casualties on expressways and massive disruptions in aviation.
Researchers published a study in Current Biology identifying the specific cellular traits that allow mangroves to survive in saltwater, unlike most terrestrial plants. By analyzing 34 mangrove species, scientists found that these plants possess unusually small leaf epidermal pavement cells and thicker cell walls, providing the mechanical strength needed to tolerate low osmotic potentials. Unlike their inland relatives, mangroves do not reduce their stomata size, allowing them to maintain high photosynthetic rates. These adaptations are crucial as rising sea levels threaten coastal regions. Mangroves also provide vital ecosystem services, including erosion protection and habitats for diverse wildlife.
- Mangroves have evolved 30 times over the last 200 million years to adapt to saline environments.
- Key adaptations include small epidermal cells and thick cell walls to handle osmotic pressure.
- Some species use waxy root layers to filter salt, while others excrete salt through specialized leaf tissues.

Air pollution has evolved into a nationwide health crisis in India, significantly impacting life expectancy and causing nearly two million deaths annually. While often associated with northern winters, toxic air now affects almost every demographic across the country. Fine particulate matter (PM 2.5) is linked to cardiovascular diseases, respiratory illnesses, and even neurological impairments. The article calls for a shift from a purely environmental perspective to a health-centered framework, emphasizing the need for stricter industrial controls, waste management reforms, and the recognition of clean air as a fundamental human right. Enforcement of existing programs remains a critical challenge.
- Nearly 46% of Indians live in regions where air pollution reduces life expectancy by more than eight years.
- PM 2.5 particles can cross the blood-brain barrier, potentially leading to neuroinflammation and cognitive decline.
- The National Clean Air Programme (NCAP) has initiated some improvements, but enforcement remains weak.
At the COP30 climate talks in Belem, Brazil, national pavilions served as microcosms of global geopolitics. China's pavilion showcased innovation with 'tea-infused fabric' and eco-friendly gifts, reflecting its status as a manufacturing powerhouse for green tech. In contrast, India's pavilion was described as 'austere,' focusing on its commitment to sustainable development without the same level of promotional giveaways. The article highlights the tension between developed and developing nations regarding fossil fuel phase-outs, with China and India emphasizing adaptation and the financial support needed for a green transition. The event was briefly interrupted by a fire near the Africa pavilion.
- COP30 was held in Belem, Brazil, with a focus on climate adaptation and funding for developing nations.
- China utilized its pavilion to rebrand its image from a producer of toxic plastics to a leader in sustainable materials.
- India remains the third-largest solar producer globally, yet over 70% of its electricity still comes from coal.
A study by research outfit iForest suggests that official 'fire counts' used to track stubble burning in Punjab and Haryana may be misleading. While government data claims a 90% reduction in fires since 2021, 'burnt-area' measurements show only a 30% decline. The discrepancy arises because satellites like Suomi-NPP (VIIRS) and Aqua (MODIS) only pass over India at specific times, missing fires that occur in the evening. Geostationary satellites like Meteosat, which provide data every 15 minutes, indicate that many fires happen outside the detection windows of polar-orbiting satellites, leading to significant undercounting of emissions.
- Burnt-area measurements show a 30% decline in stubble burning, contrasting with the 90% reduction claimed via fire counts.
- Current satellite sensors like VIIRS and MODIS only capture active fires during specific daytime windows (10:30 AM to 1:30 PM).
- Small fires and those occurring in the evening are frequently missed by polar-orbiting satellites.
This article highlights the ecological importance of grasslands, often misclassified as 'wastelands' since the colonial era. Unlike forests, where biomass is above ground, grasslands store significant carbon in their deep, fibrous root systems and soil. Restoring degraded grasslands, such as the Banni Grassland in Gujarat, significantly increases Soil Organic Carbon (SOC). Grasslands support millions of pastoralists and diverse biodiversity. The study emphasizes that grassland restoration is a cost-effective strategy for India to meet its climate goals and improve soil health, moisture retention, and erosion control.
- Grasslands store more carbon below ground in roots and soil compared to forests.
- The Banni Grassland stores 27 metric tonnes of carbon up to 30 cm depth.
- Restored grassland sites showed a 50% increase in Soil Organic Carbon (SOC) compared to untreated sites.
A study by the M.S. Swaminathan Research Foundation (MSSRF) across seven Indian states highlights that women face unique and amplified health risks due to rising temperatures. In high Heat Vulnerability Index (HVI) districts, 70% of women reported symptoms like fatigue, dizziness, and gastrointestinal discomfort. Beyond physical health, heat stress leads to mental distress, reproductive health issues, and significant wage losses, particularly for those in informal work. The report notes a strong correlation between extreme heat and increased household tensions or domestic violence, urging for gender-specific heat preparedness strategies in climate policies.
- Women in high HVI districts experience severe physical symptoms and reproductive health disruptions during peak heat.
- Nearly 97% of surveyed women reported wage losses exceeding ₹1,500 during summer months.
- Extreme heat is linked to a 38% increase in domestic violence and heightened psychosocial stress.
Observed on December 5, World Soil Day 2025 focuses on the theme "Healthy Soils for Healthy Cities." With over 56% of the global population living in urban areas, the article emphasizes that urban soil is a vital but overlooked resource. Healthy soil acts as a carbon sink, manages floodwaters, and reduces the "heat island" effect. However, urban soils face threats from "sealing" by concrete, industrial waste, and compaction. The article calls for a "blueprint for action," including urban soil restoration, promoting green infrastructure, and encouraging community gardening to enhance urban food security and mental well-being.
- Urban soils are critical for combating climate change by sequestering carbon and acting as natural air conditioners in 'heat islands.'
- The 'sealing' of soil with concrete prevents groundwater recharge and increases the risk of urban flooding during intense rainfall.
- The FAO reports that nearly one-third of the world's soils are already degraded, a problem intensified in densely populated urban centers.
India is facing a deepening crisis of human-wildlife conflict, with habitat fragmentation forcing animals like elephants into human-dominated landscapes. Between 2009 and 2021, 186 elephants were killed by train hits alone. In response, the Centre has rolled out the National Human-Wildlife Conflict Mitigation Strategy and Action Plan. This strategy focuses on addressing key drivers like damaged corridors and retaliatory killings through data-driven monitoring and stronger habitat protection. The article also notes the catastrophic decline of vulture species due to habitat disruption and poisoning, leading to public health risks from rotting carcasses and rising stray dog populations.
- Assam, West Bengal, and Odisha report the highest number of elephant casualties on railway tracks in India.
- The National Human-Wildlife Conflict Mitigation Strategy aims to promote mitigation measures and data-driven monitoring.
- Habitat fragmentation is a primary driver of animals straying into farmland and towns, leading to deaths on both sides.
While India has reformed its mining laws to encourage exploration of critical minerals like lithium and cobalt, it lacks large-scale processing and refining capacity. Currently, most raw ores are sent abroad, primarily to China, for refining into battery-grade materials. The article suggests five steps: establishing Centres of Excellence for innovation, unlocking secondary resources from industrial waste like fly ash, upskilling the workforce in hydrometallurgy, de-risking investments through government off-take commitments, and pursuing 'mineral diplomacy' to acquire processing technology. Processing is the 'missing link' that determines if India remains a raw material supplier or becomes a clean energy leader.
- China controls over 90% of global rare earth and graphite refining, creating a significant supply chain vulnerability for India.
- India's Mines and Minerals (Development and Regulation) Act has been amended to support domestic mining through exploration licenses.
- Secondary sources like red mud from aluminum plants and fly ash from coal plants contain valuable rare earth elements.
This article critiques popular urban metrics like the UN-Habitat City Prosperity Index and the Global Liveability Index. It argues that these indices often focus on stability, healthcare, and culture while ignoring a city's resilience to extreme weather events. For instance, cities like Chennai or Bangkok might score well on connectivity but lack adequate drainage for 21st-century cloudbursts. The author suggests that these indices create a 'modernity' bias, where visible infrastructure like airports is prioritized over essential but 'thankless' tasks like desilting canals or enforcing building codes in flood-prone zones, leading to skewed investment priorities.
- Current liveability indices fail to account for how well a city can withstand climate shocks like floods or heatwaves.
- There is a 'modernity' bias that favors visible infrastructure over resilient urban planning and maintenance.
- Indices often use city-wide averages, masking the vulnerability of low-income residents in flood-prone areas.
A recent 2:1 majority judgment by the Supreme Court has reviewed its earlier stance on post facto environmental clearances (ECs). Previously, the court had declared such retrospective clearances illegal, emphasizing that environmental laws require prior approval to prevent irreversible damage. The new judgment suggests that in some situations, retrospective ECs might be permissible to avoid 'public interest' issues like halting completed projects. Critics argue this undermines the 'precautionary principle' and the 'polluter pays' principle, potentially encouraging industries to bypass initial regulations and seek regularisation later through fines, marking a retreat from established environmental jurisprudence.
- The judgment reviews the 2025 CREDAI vs Vanashakti case regarding the legality of post facto environmental clearances.
- The majority view argues that a total ban on retrospective clearances could lead to economic waste for completed projects.
- The dissenting opinion by Justice Ujjal Bhuyan warns that this shifts the goalpost from principle to expediency.
Cyclone Ditwah, after causing significant fatalities in Sri Lanka, brought intense rainfall to Chennai and Andhra Pradesh. Despite the Greater Chennai Corporation (GCC) spending ₹5,200 crore on storm water drains since 2015, the city faced widespread waterlogging and flooding. The article criticizes the lack of transparency regarding the Thiruppugazh Committee report and the absence of a consolidated implementation plan. It highlights that while integrated projects handle intense bursts, they struggle with prolonged heavy rain. The need for shared flood maps, proper zoning, and basin-wide coordination is emphasized to prevent recurring urban disasters in flat coastal cities.
- Cyclone Ditwah caused at least 474 deaths in Sri Lanka before moving towards the Indian coast as a deep depression.
- Chennai's storm water drain network, though expanded, remains vulnerable to prolonged high-intensity rainfall due to incomplete links.
- The Thiruppugazh Committee was appointed after the 2021 floods to provide basin-wise recommendations for flood mitigation.

Data from the 2025 paddy harvesting season shows a 90% reduction in stubble burning incidents in Punjab and Haryana compared to 2021, reaching a five-year low. Despite this, Delhi's air quality remains in the 'very poor' to 'severe' category. This disparity indicates that local sources, such as traffic emissions (NO2 and CO) and year-round industrial activity, are the primary drivers of the city's pollution. The Supreme Court has noted that farmers should not be made scapegoats. The report identifies several 'pollution hotspots' in Delhi where PM2.5 levels consistently exceed standards, regardless of farm fire contributions.
- Stubble burning in Punjab and Haryana has significantly declined, contributing less than 5% to Delhi's pollution on most days in 2025.
- Delhi's pollution is increasingly driven by local factors like vehicular exhaust and stagnant winter weather conditions.
- Specific areas like Jahangirpuri, Bawana, and Wazirpur have been identified as persistent pollution hotspots with extreme PM2.5 levels.
This analysis highlights the severe environmental degradation in India, specifically focusing on the Aravalli range and rising pollution levels. It criticizes recent legislative changes, such as the Forest (Conservation) Amendment Act 2023 and the Draft EIA Notification 2020, for easing clearances for industrial projects at the cost of ecological health. The article notes high levels of uranium contamination in Delhi's groundwater and the weakening of the National Green Tribunal (NGT). It calls for a 'new deal for the environment' involving better coordination between the Centre and States through cooperative federalism and a whole-of-government approach to pollution.
- The Aravalli range is facing desertification and illegal mining due to relaxed government regulations and height limit exemptions.
- Recent amendments to the Forest (Conservation) Act and Coastal Regulation Zone (CRZ) rules are seen as undermining environmental protection.
- Groundwater in Delhi and Punjab shows uranium contamination levels significantly above permissible limits for human consumption.
As the 30th edition of the Conference of Parties (COP30) begins in Belém, Brazil, there is a growing call for developing nations, particularly in South Asia, to take the lead in climate negotiations. With the U.S. potentially withdrawing from the Paris Agreement again, regional cooperation becomes crucial. South Asia faces severe risks from monsoon floods, heatwaves, and glacial melts. The region's priorities for COP30 include predictable climate finance, technology transfer, and the operationalization of the Global Goal on Adaptation. A 'South Asian resilience finance facility' is proposed to channel funds into nature-based solutions.
- South Asia houses nearly two billion people facing extreme climate risks like glacial lake outbursts and heatwaves.
- Only 5% of 203 initiatives launched since 2015 have achieved their stated climate goals, highlighting an implementation gap.
- The 'Baku to Belém Roadmap' aims for $1.3 trillion in climate finance to support global transition efforts.
The Union Ministry of Tribal Affairs has introduced a new policy framework, 'Reconciling Conservation and Community Rights,' for the relocation of forest-dwelling communities from tiger reserves. The policy reiterates that relocation must be a last resort, voluntary, and compliant with the Forest Rights Act (FRA), 2006. It mandates informed consent from Gram Sabhas and individual households. Despite these guidelines, many Scheduled Tribes allege they are being pressured to relocate without their ancestral land rights being recognized. The National Tiger Conservation Authority (NTCA) has directed States to prioritize relocations, leading to protests and legal challenges in states like Karnataka regarding traditional land rights.
- Relocation from tiger reserves must be voluntary, scientifically justified, and compliant with the Forest Rights Act (FRA).
- The Forest Rights Act (FRA), 2006, protects the rights of forest-dwelling Scheduled Tribes to live in their habitats.
- Informed consent from Gram Sabhas is mandatory before any administrative notification for relocation can be issued.
The Union Government has notified the 'Sustainable Harnessing of Fisheries in the Exclusive Economic Zone (EEZ)' rules to regulate deep-sea fishing. The rules prioritize fishermen cooperative societies and Fish Farmer Producer Organisations (FFPOs) for operating technologically advanced vessels. The initiative aims to enhance seafood exports through value addition, traceability, and certification while conserving marine biodiversity. It prohibits harmful practices like LED light fishing and pair trawling. In island regions like Andaman & Nicobar and Lakshadweep, which account for 49% of India's EEZ, the use of mother-and-child vessels will be promoted to boost high-quality fish exports and sustainable livelihoods.
- New rules regulate fishing operations within India's Exclusive Economic Zone (EEZ) beyond 12 nautical miles.
- Priority is given to cooperatives and FFPOs to manage technologically advanced deep-sea vessels.
- Harmful practices such as LED light fishing and bull trawling are banned to protect the marine ecosystem.

- The incident underscores the challenges of managing human-wildlife interfaces near protected forest areas in Karnataka.
Data from satellite imagery indicates that the area affected by stubble burning in three major Punjab districts—Amritsar, Taran Taran, and Ferozpur—is 20% lower than last year. While fire counts are often used as a metric, experts argue that 'burnt area' is a more accurate indicator of the scale of the problem. Despite the reduction, there was a sharp spike in fire counts in early November, attributed to the narrow window for sowing the rabi crop. The government continues to monitor fire counts daily but does not regularly disclose the total burnt area, which is crucial for accurate environmental assessment.
- Burnt area is considered a more accurate metric for assessing stubble burning impact than simple fire counts, which can be misleading.
- Amritsar, Taran Taran, and Ferozpur are the three major districts in Punjab showing a significant reduction in burnt area this year.
- Satellite imagery from firms like Suhora Technologies helps in analyzing the extent of farm fires by looking at 'burnt scars' on the landscape.
