India’s deserts, grasslands, and savannas are collectively referred to as open ecosystems they are ecologically rich and culturally significant landscapes. However, these areas have been misclassified as “wastelands” in official policy and land-use records, a designation that overlooks their vital biodiversity and societal value.

Understanding Open Ecosystems:

Open ecosystems, such as deserts, grasslands, scrublands, and savannas, are characterized by sparse tree cover and vast expanses of herbaceous or shrubby vegetation. These landscapes are not barren or useless but are highly adapted to extreme environmental conditions and support diverse life forms.

• Deserts, which cover about one-third of Earth's terrestrial surface, host unique flora and fauna that are adapted to the harsh conditions of aridity. These regions have also been home to ancient civilizations like those in Mesopotamia, Egypt, and the Indus Valley, which thrived in desert climates.

• Despite the popular misconception, these ecosystems are not barren wastelands but are ecologically intricate and biodiverse landscapes.

The Legacy of ‘Wastelands’ Misclassification:

The classification of vast stretches of grasslands, savannas, and scrublands as “wastelands” traces its roots to colonial-era land-use frameworks. The term “wasteland” has been historically used to categorize natural ecosystems that were seen as unproductive and in need of transformation, often through afforestation, agriculture, or industrial use.

• Government records have classified millions of hectares of these ecosystems as “wastelands,” leading to extensive ecological damage. This misclassification has diminished the importance of these lands, resulting in the loss of ecosystem services such as:

  • Carbon sequestration,

  • Soil fertility,

  • Water retention, and

  • Biodiversity conservation.

Ecological and Social Value of Open Landscapes:

India's open ecosystems are vital to the survival of many endangered and endemic species. These include:

• The Great Indian Bustard,

• Caracal,

• Indian Wolf, and

• Chinkara.

These species rely on the specific structure and seasonal rhythms of open habitats to survive and thrive. Additionally, grasslands and savannas play a critical role in carbon storage. While tree-based carbon storage often receives more attention, grasslands and savannas store significant amounts of carbon deep in the soil, making them important in the fight against climate change.

Beyond their ecological value, open ecosystems are also crucial to the livelihoods of millions of pastoralist communities. For example:

• The Dhangars of Maharashtra,

• The Rabaris of Gujarat, and

• The Kurubas of Karnataka,

These communities depend on open landscapes for grazing and have historically acted as custodians of ecosystem health, employing practices such as rotational grazing and water conservation.

However, policies that encourage fencing, tree planting, or land repurposing often lead to the displacement of these communities, loss of income, and the erosion of traditional ecological knowledge.

The Issue with Current Land Restoration and Greening Goals:

A significant issue arises with the tendency to “green” open ecosystems, especially deserts and grasslands, through tree plantations. This approach stems from a mistaken belief that tree cover is the only indicator of ecological health. While afforestation can be beneficial in certain contexts, the widespread planting of trees in these areas can lead to:

• Monoculture plantations,

• Degradation of local biodiversity, and

• Disruption of seasonal ecological cycles.

Experts argue for a more holistic, community-driven approach to ecosystem restoration, emphasizing strategies such as:

• Protecting native vegetation and allowing natural regeneration,

• Promoting soil and moisture conservation,

• Drawing on indigenous land management knowledge, and

• Recognizing the importance of carbon stored in soil as a key metric for climate change mitigation.

Policy Recommendations

To ensure the sustainable management and protection of India’s open ecosystems, experts advocate for the following policy reforms:

1. Revising Land Classification Systems: The “wasteland” label should be removed and replaced with a more accurate classification that reflects the ecological and cultural value of these landscapes.

2. Formulating Ecosystem-Specific Conservation Plans: National and regional conservation strategies should be tailored to the unique needs of each open ecosystem, such as grasslands, deserts, and savannas.

3. Recognizing Pastoralist Rights and Stewardship: Policies must acknowledge and support the role of pastoralist communities in maintaining ecosystem health. Their traditional knowledge should be incorporated into land-use and conservation strategies.

4. Integrating Open Ecosystems into National Strategies: Open ecosystems should be incorporated into national climate and biodiversity frameworks, with a focus on their role in carbon storage, water retention, and biodiversity conservation.

5. Incentivizing Soil Carbon Conservation: Policymakers should encourage the conservation of soil carbon in open ecosystems alongside forest carbon, creating financial incentives for sustainable practices.

Additionally, experts suggest symbolic shifts, such as renaming the World Day to Combat Desertification and Drought to “World Day to Combat Land Degradation”, in order to recognize the ecological legitimacy of deserts, grasslands, and other open landscapes.

Conclusion:

India’s deserts, grasslands, and savannas are misunderstood ecosystems that hold immense ecological, cultural, and economic value. To ensure their sustainability and protection, policymakers must re-evaluate how these landscapes are classified and managed.

The crash of Air India AI 171 in Ahmedabad, which led to the tragic death of 241 passengers and crew members, has raised serious concerns. The Aircraft Accident Investigation Bureau (AAIB), tasked with investigating such incidents, released a preliminary report that pointed out a significant issue: both engine fuel control switches moved from the 'RUN' to 'CUTOFF' position shortly after takeoff. This triggered a massive investigation, as such switches rarely move accidentally.

A crucial moment came when one pilot allegedly questioned the other about cutting off the fuel, but the response was a denial. This incident prompted a closer examination of the Cockpit Voice Recorder (CVR) and Flight Data Recorder (FDR), as both could provide vital information to understand the chain of events leading to this disaster.

The Investigation Protocols:

Under the 1944 Chicago Convention, aircraft crash investigations are generally conducted by the State of Occurrence, i.e., the country where the accident took place. However, other states involved with the aircraft's registration, operation, design, or manufacture have the right to participate. This process ensures a multinational investigation in the event of an aviation accident.

• State of Occurrence: The country where the accident happens.

• State of Registry: Where the aircraft is registered.

• State of Operator: The country where the airline operates the flight.

• State of Design: The country that oversees the design of the aircraft.

• State of Manufacture: The country that manages the final assembly of the aircraft.

These roles are governed by Annex 13 of the Chicago Convention, and ensure a transparent and thorough investigation by a multi-agency approach.

AAIB: India's Independent Investigation Body

The Aircraft Accident Investigation Bureau (AAIB), established in 2012, is India's independent body responsible for investigating aviation accidents and serious incidents. This independent status was critical to ensure that investigations are not influenced by regulatory bodies such as the Directorate General of Civil Aviation (DGCA).

Legal and Regulatory Framework:

• Aircraft Act, 1934: Grants the Indian government the power to regulate and investigate aviation accidents.

• Aircraft (Investigation of Accidents and Incidents) Rules, 2012: Formalizes AAIB’s role, which was later amended in 2017 and 2021.

• AAIB's Role: The AAIB operates independently as an Attached Office of the Ministry of Civil Aviation, ensuring unbiased and transparent investigations.

Key Functions and Role of AAIB:

1. Accident Classification: AAIB classifies aviation occurrences into Accidents, Serious Incidents, and Incidents.

2. Unrestricted Access to Evidence: AAIB has immediate and unrestricted access to all relevant evidence, such as flight records, testimonies, and wreckage, even before judicial approval.

3. Focus on Safety, Not Liability: AAIB investigations focus on identifying the root causes of accidents to prevent future occurrences, not on assigning blame or liability. This is in line with Rule 3 of the Aircraft (Investigation of Accidents and Incidents) Rules, 2017.

4. Investigation of Major Aircraft: AAIB investigates all accidents and serious incidents involving aircraft weighing over 2,250 kg and Turbojet aircraft.

The Investigation Process:

1. Immediate Site Investigation: Upon an accident, the AAIB dispatches investigators to the site to collect and preserve perishable evidence, such as wreckage samples and black boxes (CVR and FDR).

2. Evidence Collection: The AAIB collects data from:

   • Operators (airlines).

   • Regulators (DGCA).

   • Involved Personnel.

   • Any other relevant materials that could shed light on the accident.

3. Expert Analysis: AAIB often works with domain experts and collaborates with organizations like Hindustan Aeronautics Limited and DGCA laboratories for in-depth analysis.

4. Final Report Preparation: After thorough internal review, the AAIB publishes a final investigation report, which is shared with the International Civil Aviation Organization (ICAO) and other relevant states.

Additional Functions of AAIB:

• Safety Studies: AAIB also conducts safety studies to understand broader trends in aviation safety.

• Safety Recommendations: Based on findings from investigations, AAIB may issue safety recommendations to organizations like the DGCA or international aviation bodies. These recommendations aim to improve safety protocols, reduce risks, and prevent similar incidents in the future.

Conclusion:

The AI 171 crash has once again highlighted the critical role of independent investigations in aviation safety. The AAIB's investigation into this incident, with its focus on preventing future accidents rather than assigning blame, will be key to improving aviation safety standards in India and beyond

The Carbon Credit Trading Scheme (CCTS) is a market-driven initiative developed under the Indian Carbon Market (ICM), aimed at regulating and trading carbon credits to facilitate the reduction of greenhouse gas (GHG) emissions in key industrial sectors in India.

Key Objectives of CCTS:

• Decarbonisation of Industrial Sectors: The scheme is designed to decarbonise high-emission sectors in India by shifting the focus from just improving energy efficiency (as seen in the earlier PAT Scheme) to directly reducing GHG emissions intensity.

• Monetary Value for GHG Emissions: CCTS assigns a monetary value to carbon emissions, making it financially beneficial for industries to reduce their carbon footprint.

• Accelerating Transition to Low-Carbon Economy: It supports India’s broader goal of transitioning to a low-carbon economy, helping meet international climate commitments and national climate goals.

Transition from PAT to CCTS:

• The Perform, Achieve, and Trade (PAT) scheme, which focused primarily on energy efficiency improvements in energy-intensive sectors, has now been superseded by the CCTS.

• PAT Scheme: Issued Energy Saving Certificates (ESCerts) based on energy efficiency improvements.

• CCTS: Shifts focus to GHG emissions intensity and issues Carbon Credit Certificates (CCC), each representing 1 tonne of CO₂ equivalent reduced. The certificates can be traded in the market.

Key Features of CCTS:

1. Compliance Mechanism:

   • Obligated Sectors: Industries in the sectors covered by the CCTS must meet sector-specific emissions intensity targets.

   • Earned Carbon Credit Certificates (CCC): Entities that exceed their emissions intensity reduction targets earn tradable Carbon Credit Certificates (CCC).

   • Buying and Selling Credits: Entities that fail to meet their targets must buy carbon credits from others who have surplus credits, incentivizing emissions reductions across sectors.

2. Offset Mechanism:

   • Voluntary Participation: Entities outside the mandated sectors can voluntarily participate by reducing emissions and earning carbon credits. This broader participation helps increase the overall carbon market's efficiency and reach.

Target Sectors Under CCTS:

The scheme mandates participation from eight high-emission industrial sectors that contribute around 16% of India’s total GHG emissions. These sectors include:

1. Aluminium

2. Cement

3. Pulp & Paper

4. Chlor-Alkali

5. Iron & Steel

6. Textiles

7. Petrochemicals

8. Refineries

These sectors are required to meet emission intensity reduction targets set by the Bureau of Energy Efficiency (BEE).

Exclusion of Power Sector:

• The power sector, which contributes about 40% of India’s total GHG emissions, is currently excluded from the compliance mechanism of CCTS.

• There are possibilities for inclusion of the power sector in later phases of the scheme.

Alignment with India’s Nationally Determined Contributions (NDCs):

• India has committed to a 45% reduction in emissions intensity of its GDP by 2030, relative to 2005 levels, under the Paris Agreement.

• CCTS is one of the key policy instruments to help India meet these ambitious climate targets.

Significance of CCTS for India:

1. Climate Action: CCTS plays a crucial role in supporting India’s climate goals by targeting some of the most emission-intensive sectors.

2. Market-Based Mechanism: By assigning a monetary value to GHG emissions, the scheme introduces a market-based approach to incentivize emission reductions and promote sustainable industrial practices.

3. Encouraging Industry Participation: The trading aspect of the system encourages industries to reduce emissions by providing financial incentives for achieving emission reduction targets.

4. Long-Term Sustainability: By focusing on emissions intensity rather than just energy efficiency, the CCTS will contribute to the long-term decarbonisation of India’s industrial sectors, which will be essential for the country’s climate resilience and sustainable economic growth.

The CCTS is a forward-looking step in India's efforts to reduce its carbon footprint while fostering a low-carbon economy. It offers a flexible, market-driven solution to the pressing issue of industrial emissions and ensures environmental sustainability while simultaneously promoting economic growth through innovation and competitiveness.

The Special Intensive Revision (SIR) in Bihar, initiated by the Election Commission of India (ECI), has raised important discussions about electoral inclusion and migrant populations.

Who is an ‘Ordinarily Resident’?

According to Section 19 of the Representation of the People Act (RP Act), only a person who is an ‘ordinarily resident’ in a constituency can be enrolled in its electoral roll. This is a key principle to maintain the integrity and accuracy of electoral rolls.

Understanding ‘Ordinarily Resident’:

• Section 20 of the RP Act defines an ‘ordinarily resident’. It makes it clear that owning or possessing a house in a constituency doesn’t automatically qualify someone as an ordinarily resident.

• A person who is temporarily absent from their regular residence (e.g., for work or travel) is still considered an ordinarily resident in the location where they have their habitual and permanent residence.

Categories of People Considered ‘Ordinarily Resident’:

1. Armed Forces Personnel: Those serving in the armed forces, even if posted outside the state, are considered ordinarily residents of their home constituency.

2. Members of State Armed Police: Similarly, those serving outside their home state are considered ordinarily residents in their original constituency.

3. Central Government Employees: Employees working abroad for the Central Government are considered ordinarily residents of their original constituency.

4. Constitutional Office Holders: Persons holding a constitutional office, as declared by the President in consultation with the Election Commission, and their spouses, are also considered ordinarily residents.

Non-Resident Indians (NRIs) and Voting Rights:

• Section 20A of the RP Act (introduced in 2010) allows Non-Resident Indians (NRIs) to register and vote from the address listed in their passport, even if they live abroad for extended periods. This ensures that NRIs can still participate in the democratic process.

Rules Governing Electoral Rolls:

• Registration of Electors Rules, 1960 (RER): These rules govern the preparation of electoral rolls and the inclusion and exclusion of names. The ECI oversees this process to ensure that only eligible voters are included, and the electoral roll remains accurate.

Why the ‘Ordinarily Resident’ Status Matters:

1. Ensuring Genuine Connection: The ‘ordinarily resident’ requirement ensures that voters have a genuine and habitual connection with the constituency where they are voting. This is crucial for the authenticity of the electoral process.

2. Maintaining Electoral Integrity: It helps in maintaining electoral integrity, minimizing fraudulent registrations, and ensuring that only those with a true connection to a constituency are eligible to vote.

3. Accountability in Representation: By ensuring that voters are genuinely connected to a constituency, this system enhances accountability in the electoral system.

Court Ruling on ‘Ordinarily Resident’ Status:

• In the Gauhati High Court (1999, Manmohan Singh Case), it was ruled that:

  • A person must be a habitual and permanent resident of a constituency.

  • There must be an intention to dwell in that place.

  • A reasonable person should be able to accept the individual as a resident of the constituency.

Conclusion:

The ‘ordinarily resident’ status is a key concept in determining voter eligibility in India. It ensures that only those with a genuine, habitual connection to a constituency can participate in its electoral process.

On July 1, 2025, scientists using the ATLAS telescope in Chile announced the discovery of an extraordinary interstellar object named 3I/ATLAS, which has been tracked since June 14, 2025.

About 3I/ATLAS

1. Classification:

   • 3I/ATLAS is an interstellar comet, meaning it originates from outside our solar system.

   • Its highly elliptical orbit and fast velocity through space distinguish it from other solar system objects, making it a unique interstellar visitor.

2. Orbit and Speed:

   • The comet travels at speeds of 57–68 km/s relative to the Sun, much faster than objects within the solar system.

   • Its hyperbolic trajectory indicates it will pass through the solar system only once, without returning.

   • The comet's trajectory traces back to the constellation Sagittarius, indicating its origin lies far beyond our solar system, possibly from the Milky Way’s thick disk.

3. Key Dates:

   • Closest approach to Earth: About 270 million km.

   • Closest approach to the Sun: Expected on October 29–30, 2025, at a distance of around 210 million km, which is slightly within Mars’s orbit.

Physical Characteristics and Observations:

• Active Comet: 3I/ATLAS is confirmed to be an active comet, displaying a visible coma (a cloud of ice particles and dust) surrounding its nucleus.

• As it nears the Sun, it is expected to develop a tail, a characteristic feature of comets formed by the heating of the comet’s surface by the Sun.

• Reddish Hue: The comet has been observed to have a reddish hue, and its spectral characteristics suggest that its surface may be rich in complex organic compounds or water ice.

• Size: The nucleus of 3I/ATLAS is estimated to be 10–30 km wide, making it larger than previous interstellar visitors:

  • 1I/ʻOumuamua (2017): The first known interstellar object.

  • 2I/Borisov (2019): The second interstellar comet discovered.

• Composition and Rotation: The composition and rotation period of the comet are under active study using ground-based telescopes worldwide.

About Comets

1. Composition:

   • Comets are icy celestial bodies made up of frozen gases like water, ammonia, methane, and carbon dioxide, mixed with rocky and metallic dust.

2. Orbits:

   • Comets have highly elliptical orbits that take them far from the Sun and then close to it, unlike the near-circular orbits of planets.

   • Short-period comets originate from the Kuiper Belt, while long-period comets are thought to come from the distant Oort Cloud (located between 5,000–100,000 AU from the Sun).

3. Comet Features:

   • As comets approach the Sun, they heat up and release gases and dust, forming a coma (a cloud around the nucleus) and sometimes a tail.

   • One of the most famous comets, Halley’s Comet, visits Earth once every 76 years, with its last appearance in 1986.

Conclusion:

The discovery of 3I/ATLAS provides scientists with a rare opportunity to study a comet from outside our solar system, which could offer clues about the early solar system and the formation of celestial bodies.
