Eco-Sensitive Zone Guidelines

Eco-Sensitive Zone Guidelines



The Standing Committee of the National Board for Wildlife (SC-NBWL) has recently called for a reassessment of the guidelines governing Eco-Sensitive Zones (ESZs). The committee emphasises a flexible and site-specific approach that balances conservation with local socio-economic needs. This move follows concerns that current uniform ESZ rules may hinder development without proportional ecological benefits.

What Are Eco-Sensitive Zones?

Eco-Sensitive Zones are buffer areas around protected forests, wildlife sanctuaries, and national parks. They aim to shield biodiversity from harmful human activities like mining, construction, and polluting industries. Some activities such as farming, eco-tourism, and renewable energy use are allowed but with restrictions to minimise environmental impact.

Concerns Over Uniform ESZ Rules

The committee brought into light that applying a blanket 10-kilometre ESZ around all protected areas ignores local ecological and geographical differences. For example, in Himachal Pradesh where 65% of land is forest or protected, strict ESZ rules could block development without ecological gain. Similarly, small sanctuaries or marine ecosystems are poorly served by current terrestrial-focused guidelines.

Challenges Faced by Local Communities

Officials from various states reported hardships caused by rigid ESZ restrictions. Activities like mining and industry face prohibitions that affect local livelihoods. Unlike protected areas, ESZs do not offer compensation for affected people. This has led to resistance against ESZ notifications and delays in declaring new protected zones.

Proposals for More Flexible Approaches

Suggestions include adapting ESZ limits based on local conditions and allowing transitional periods for existing activities. For instance, Karnataka proposed a two-year phase-out for restricted activities after ESZ notification. Stakeholder consultations involving state governments, ministries, and experts are recommended before finalising ESZ boundaries and rules.

Need for Inter-Ministerial Coordination

The committee urged the environment ministry to prepare a detailed note on ESZ issues. This will be followed by consultations with relevant divisions and a joint meeting of ESZ and wildlife departments. The aim is to develop guidelines that provide strong ecological safeguards while accommodating socio-economic realities.

Sectoral Impact of ESZ Guidelines

Mining, highways, railways, housing, and tourism sectors are most affected by ESZ regulations. The committee recognised that a one-size-fits-all ESZ approach may delay infrastructure projects and economic activities. Tailored guidelines could help balance conservation goals with development needs.

Global Plastic Ban Could Save Trillions by 2040

Global Plastic Ban Could Save Trillions by 2040



Recent studies show the urgent need for an immediate ban on problematic single-use plastics. Research commissioned by the World Wide Fund for Nature (WWF) and conducted by Earth Action (EA) suggests that banning items like straws, cotton buds and packaging made from polystyrene could save the global economy trillions of dollars by 2040. The findings reveal that quick action is far more effective than gradual phase-outs in reducing environmental harm and economic costs.

Problematic Plastics

Problematic plastics are those likely to pollute the environment and harm human health. This includes expanded polystyrene, polyvinyl chloride, and single-use items such as cotton buds and straws. These plastics often escape proper waste management and cause pollution.

Global Plastic Production and Waste

Humans produce about 430 million tonnes of plastic annually. Of this, 280 million tonnes become waste. Nearly half is landfilled, but 22% is mismanaged and pollutes ecosystems. Mismanaged waste is neither recycled nor properly disposed of, leading to environmental damage.

Economic Impact of Bans Versus Business as Usual

The study compares a business-as-usual (BAU) scenario with various ban and phase-out models. Under BAU, total costs of plastic production, consumption and social impacts could reach $10 trillion between 2025 and 2040. An immediate global ban on targeted plastics would cost $2 trillion but save $8 trillion compared to BAU. A phased approach would save $7 trillion, while staggered bans between high- and low-income countries would save $4.7 trillion.

Environmental Benefits of Immediate Ban

An immediate ban could reduce plastic consumption by 173 to 224 million tonnes and cut mismanaged waste by 51 to 74 million tonnes by 2040. This reduction lowers greenhouse gas emissions and lessens pollution in oceans and land.

Cost Components and Private Sector Impact

Administrative costs for an immediate ban are estimated at $323 million. However, waste management savings of $50 billion far exceed these expenses. Transition costs for the private sector are around $143 million, with market losses of $228 billion due to shrinking plastic markets. Yet, new economic opportunities in reusable products and circular business models are expected to offset these losses.

Policy Scenarios and Their Modelling

Six scenarios were modelled, including full bans, phased reductions, and differentiated timelines for countries by income level. These used data from the Plasteax dataset and existing bans worldwide. The scenarios consider waste management costs and social impacts to forecast savings and costs.

Role of International Cooperation

High-income countries supporting lower-income nations in implementing bans reduce administrative costs and improve outcomes. Multilateral agreements like the Montreal Protocol serve as models for effective global environmental treaties.

Earth’s Rotation Speeds Up

Earth’s Rotation Speeds Up


Recent observations show that Earth’s rotation is accelerating. On 9 July 2025, the planet completed one full spin faster than ever before. This day was shorter by approximately 1.6 milliseconds. Scientists attribute this change to the gravitational influence of the Moon. The phenomenon has implications for timekeeping and scientific study.

Earth’s Rotation and Day Length

Earth’s day length is not constant. It varies due to factors such as gravitational forces, seismic activity, and changes in atmospheric conditions. The Moon’s position affects Earth’s spin by exerting tidal forces. These forces can speed up or slow down the rotation slightly. The 9 July 2025 event marks the shortest day since records began.

Shorter Days in 2025

Following 9 July, other days like 22 July and 5 August 2025 are also expected to be shorter. These repeated speed-ups show a pattern of Earth’s rotation accelerating temporarily. Scientists monitor these changes closely to understand their causes and predict future variations.

Leap Seconds and Timekeeping

To keep clocks aligned with Earth’s rotation, leap seconds are added or subtracted. Since 1972, 27 positive leap seconds have been inserted to compensate for Earth’s slowing spin. A leap second is usually added at the end of June or December. However, due to the recent acceleration, a negative leap second is planned for 2029. This will be the first time a second is removed from Coordinated Universal Time (UTC).

Negative Leap Second Explained

A negative leap second subtracts one second from the official time to correct for faster Earth rotation. This adjustment ensures that atomic clocks remain in sync with astronomical time (UT1), which is based on Earth’s actual spin. The International Earth Rotation and Reference Systems Service (IERS) is responsible for monitoring Earth’s rotation and deciding on leap second adjustments.

Scientific Significance

While the shorter days do not pose any danger, they challenge scientists and timekeepers. Precise timekeeping is critical for navigation, communication, and scientific research. Understanding the factors behind Earth’s rotation changes helps improve models of Earth’s interior and its interaction with the Moon and Sun.

Atomic Time vs Astronomical Time

Atomic time (UTC) is measured using highly stable atomic clocks worldwide. Astronomical time (UT1) depends on Earth’s rotation. When these two time scales diverge by 0.9 seconds or more, leap seconds are introduced to realign them. Recent faster rotation means UT1 is ahead of UTC, prompting the need for a negative leap second.

Melting Ice Caps Trigger Increased Volcanic Eruptions Risk


Melting Ice Caps Trigger Increased Volcanic Eruptions Risk



Recent studies reveal that melting glaciers and ice caps may lead to more frequent and explosive volcanic eruptions. The greatest threat lies in West Antarctica, where around 100 volcanoes remain buried beneath thick ice. As global temperatures rise, this ice is expected to vanish over coming decades and centuries. This phenomenon was brought into light at the 2025 Goldschmidt Conference in Prague, the premier international event on geochemistry

Impact of Ice Melt on Volcanic Activity

Glaciers and ice caps exert immense pressure on underground magma chambers. When these ice masses melt, the pressure decreases. This reduction allows magma and gases to expand, increasing the likelihood of explosive eruptions. Historical evidence from Iceland shows that volcanic activity surged 30 to 50 times during the last deglaciation, about 15,000 to 10,000 years ago.

Regions at Risk Beyond Antarctica

Besides West Antarctica, other areas such as parts of North America, New Zealand, and Russia may also experience increased volcanic activity. These regions have glaciers or ice caps that are retreating due to climate change, potentially triggering similar geological responses.

Role of Pressure and Magma Production

Lower pressure from melting ice causes rocks to melt at reduced temperatures, generating more magma. This process can build large magma reservoirs beneath volcanoes. For example, Chile’s Mocho Choshuenco volcano had suppressed eruptions during a thick ice sheet period 26,000 to 18,000 years ago. After the ice melted around 13,000 years ago, explosive eruptions occurred due to the release of built-up magma.

Influence of Precipitation on Eruptions

Climate change also alters precipitation patterns. Increased rainfall can seep deep underground, interacting with magma systems. This infiltration may trigger volcanic eruptions by affecting pressure and chemical reactions within magma chambers.

Volcanic Eruptions and Climate Feedback

Volcanic eruptions emit ash and sulfur dioxide, which can cool the Earth temporarily by blocking sunlight. Sulfur dioxide forms sulfuric acid aerosols in the stratosphere that reflect solar radiation for up to three years. However, prolonged eruptions release greenhouse gases like carbon dioxide and methane, intensifying global warming. This creates a feedback loop where warming leads to more ice melt, causing more eruptions and further warming.
