PHONE TAPPING
- Phone tapping can only be carried out with proper legal authorization. This typically involves obtaining a warrant from designated authorities, such as the Home Secretary or the Union Home Ministry, under specific conditions outlined in the law. These conditions usually involve national security concerns, threats to public order, or in the interest of preventing a crime
- Once authorized, government agencies such as law enforcement or intelligence agencies liaise with telecom service providers (TSPs) to facilitate the interception. TSPs are required to cooperate with government agencies in providing access to the targeted communication channels
- TSPs use specialised equipment to tap into phone conversations or data transmissions. This can involve the installation of intercepting devices at various points within the telecommunications infrastructure, allowing for the monitoring of phone calls, text messages, and Internet communications
- Once intercepted, the communications are typically monitored and analyzed by designated personnel within the relevant government agencies. This may involve listening to phone calls, reading text messages, or analyzing internet traffic to gather intelligence or evidence related to the authorized investigation
- There are legal safeguards in place to prevent abuse of phone tapping powers. The intercepted communications must be used strictly for the purposes authorized by the warrant, and there are provisions for judicial oversight to ensure compliance with legal procedures and protection of individual rights to privacy

Who Can Tap Phones?
In various states, police possess the authority to conduct phone tapping. At the national level, ten agencies are empowered to carry out such actions: the Intelligence Bureau, Central Bureau of Investigation (CBI), Enforcement Directorate, Narcotics Control Bureau, Central Board of Direct Taxes, Directorate of Revenue Intelligence, National Investigation Agency, Research and Analysis Wing (RAW), Directorate of Signal Intelligence, and the Delhi Police Commissioner. Any phone tapping conducted by unauthorized agencies is deemed unlawful. The regulations governing phone tapping in India are outlined in the Indian Telegraph Act of 1885
|
- Section 5(2) of the Indian Telegraph Act of 1885 stipulates that phone tapping can be authorized by the Centre or states in cases of public emergencies or for public safety reasons, provided it is deemed necessary for maintaining public safety, national sovereignty, integrity, security, friendly relations with foreign states, public order, or preventing incitement to commit offenses.
- However, there is an exemption for the press, stating that press messages intended for publication in India from accredited correspondents to the Central or State Governments shall not be intercepted or detained unless specifically prohibited. The competent authority must document the reasons for phone tapping in writing.
- According to Rule 419A of the Indian Telegraph (Amendment) Rules, 2007, phone tapping orders can only be issued by designated government officials. Orders from the Government of India are issued by the Secretary to the Ministry of Home Affairs, while those from State Governments are issued by the Secretary in charge of the Home Department. These orders must be conveyed in writing to the service provider before phone tapping can commence.
- In exceptional circumstances, such as remote areas or operational urgencies, an authorized officer, not below the rank of a Joint Secretary to the Government of India or the State Home Secretary, may issue an order. However, in such cases, the interception must be promptly reported to the competent authority, which must approve or disapprove it within seven working days. If confirmation is not received within this period, the interception must cease.
- The duration of interception orders does not exceed 60 days unless renewed, up to a maximum of 180 days. Orders must contain reasons, and copies are forwarded to a review committee within seven days. This committee, chaired by the Cabinet Secretary at the Centre or the Chief Secretary in states, reviews interception requests regularly.
- Records related to interception orders are destroyed every six months unless required for functional purposes, and service providers are required to destroy interception-related records within two months of discontinuation. Multiple provisions aim to maintain transparency and accountability throughout the process.
- Service providers are responsible for ensuring no unauthorized interception occurs, with strict penalties, including fines or license revocation, for non-compliance. They must implement internal checks to maintain extreme secrecy and prevent unauthorized interception by their employees
The Indian Telegraph Act of 1885 holds significant historical importance in the context of India's telecommunications landscape.
Here's a brief overview of its historical background:
-
Colonial Era: The Act was enacted during British colonial rule in India. It was a time when telegraphy was rapidly advancing globally and played a crucial role in communication and administration. The British colonial government in India recognized the importance of regulating telegraph services to maintain control and facilitate efficient communication across the vast territories of the Indian subcontinent.
-
Consolidation of Telegraph Services: Prior to the enactment of the Indian Telegraph Act, telegraph services in India were managed by various private companies and government departments. The Act aimed to consolidate and regulate these services under a unified legal framework, providing the colonial government with the authority to oversee and manage telegraph communication effectively.
-
Expansion of Telegraph Network: The late 19th century witnessed significant expansion in India's telegraph network, connecting major cities, towns, and administrative centers across the country. The Indian Telegraph Act provided the legal framework necessary for the establishment, operation, and maintenance of telegraph lines, stations, and equipment throughout British India.
-
Regulation of Communication: The Act empowered the colonial government to regulate telegraph communication in India. It outlined provisions for issuing licenses, collecting fees, and enforcing regulations related to telegraphy. This regulatory framework played a crucial role in ensuring the smooth functioning of telegraph services and maintaining security and order in the colonial administration.
-
Adaptation and Amendments: Over the years, the Indian Telegraph Act has undergone several amendments to keep pace with technological advancements and evolving communication needs. Subsequent amendments have expanded the scope of the Act to encompass new technologies such as telephone, internet, and digital communication, while also addressing emerging challenges related to privacy, security, and surveillance
The question of whether reforms are needed or if the Indian Telegraph Act of 1885 should be revoked entirely is a complex one, and it depends on various factors, including evolving technological advancements, legal considerations, and societal needs.
Here are some perspectives to consider:
-
Reforms within the Act: The Indian Telegraph Act, despite its age, has been subject to numerous amendments over the years to accommodate changes in technology and communication practices. Reforms within the Act could focus on updating its provisions to reflect contemporary challenges such as digital communication, cybersecurity, and privacy concerns. This might involve clarifying and strengthening provisions related to data protection, surveillance, and lawful interception while safeguarding individual rights and freedoms.
-
Modernization of Telecommunication Laws: Rather than revoking the Indian Telegraph Act outright, there could be a push for broader reforms aimed at modernizing telecommunication laws in India. This could involve drafting comprehensive legislation that addresses not only telegraphy but also other forms of communication such as telephone, internet, and digital platforms. Such legislation could provide a more coherent and adaptive framework for regulating modern communication technologies while upholding fundamental rights and principles.
-
Enhanced Oversight and Accountability: Regardless of whether the Indian Telegraph Act is retained or replaced, there is a need for enhanced oversight and accountability mechanisms to ensure that any surveillance or interception activities conducted by authorities comply with legal standards and respect individual privacy rights. This could involve establishing independent oversight bodies or strengthening existing mechanisms for judicial review and transparency in surveillance practices.
-
Public Consultation and Stakeholder Engagement: Any reforms to telecommunication laws, including the Indian Telegraph Act, should involve meaningful public consultation and engagement with relevant stakeholders, including civil society organizations, legal experts, technologists, and industry representatives. This would help ensure that any proposed changes reflect diverse perspectives and address the needs and concerns of all stakeholders.
-
International Best Practices: In considering reforms to telecommunication laws, policymakers could also look to international best practices and standards for guidance. Studying the approaches adopted by other countries in regulating communication technologies and balancing security needs with individual rights could provide valuable insights for reform efforts in India
The legality of phone tapping in India must be considered within the framework of constitutional provisions, particularly Article 21 of the Indian Constitution, which guarantees the fundamental right to privacy and personal liberty. Here's an overview of how Article 21 relates to the legality of phone tapping:
-
Article 21 - Right to Privacy and Personal Liberty: Article 21 of the Indian Constitution states that "no person shall be deprived of his life or personal liberty except according to procedure established by law." This provision is interpreted to encompass the right to privacy, which includes the right to confidentiality of communications.
-
Scope of Article 21 in the Context of Phone Tapping: Phone tapping involves the interception of private communications, which directly implicates the right to privacy protected under Article 21. Individuals have a reasonable expectation of privacy in their communications, and any intrusion into this privacy must be justified by law and meet certain procedural safeguards.
-
Legal Framework for Phone Tapping: The Indian Telegraph Act of 1885, along with subsequent amendments and rules, provides the legal framework for phone tapping in India. Section 5(2) of the Act allows for phone tapping in specific circumstances, such as public emergencies or in the interest of public safety, subject to procedural safeguards and oversight.
-
Constitutional Validity of Phone Tapping: The Supreme Court of India has upheld the constitutionality of phone tapping in certain circumstances, provided it is carried out in accordance with law and procedural safeguards. In the landmark case of K.S. Puttaswamy v. Union of India (2017), the Supreme Court recognized the right to privacy as a fundamental right under Article 21 and emphasized the need for strict adherence to legal requirements and safeguards in cases involving intrusion into privacy, including phone tapping.
-
Procedural Safeguards and Judicial Oversight: To ensure the legality of phone tapping, it must be authorized by competent authorities under the Indian Telegraph Act, and specific procedural safeguards must be followed. This includes obtaining prior authorization from designated officials, recording reasons for phone tapping, and judicial oversight to prevent abuse of power.
-
Balancing Privacy and State Interests: While Article 21 protects the right to privacy, it also allows for reasonable restrictions on this right in the interest of state security, public order, and preventing crime. The legality of phone tapping depends on striking a balance between individual privacy rights and legitimate state interests, with the requirement that any intrusion into privacy be proportionate, necessary, and authorized by law

GIG ECONOMY
| Subject | Formal Labor Market | Informal Labor Market |
| Regulation | Regulated by government laws and policies | Not regulated by formal labor laws |
| Job Security | Generally offers job security | Often lacks job security |
| Benefits | Provides benefits like health insurance and retirement plans | Rarely provides benefits |
| Legal Protections | Employees have legal protections and must adhere to standards | Workers lack legal protections |
| Income | Regular and predictable income | Irregular and uncertain income |
| Employment Contracts | Jobs usually involve formal contracts | Work is often done without formal contracts |
| Examples | Corporate jobs, government positions | Freelance work, informal vendors, day labourers |
- Maintaining the impressive growth rates of recent years into the medium to long term, while expanding the consumption base, will be difficult given that a significant portion of the country's workforce remains stuck in low-productivity jobs.
- Recent government surveys indicate that the number of informal businesses in the country has increased from 57.6 million in 2010-11 to 63.4 million in 2015-16, and further to 65 million in 2022-23
- If the economy were generating more productive employment opportunities, both the number of informal firms and the workforce within them would be significantly decreasing.
- Combining the 110 million workers in non-farm informal businesses with the approximately 230 million engaged in agriculture accounts for almost two-thirds of the labor force still employed in low-productivity jobs in less efficient sectors—sectors that now contribute an even smaller share of the total economic value added than before.
- This is in addition to those informally employed in construction and the formal parts of the economy.
- In the absence of low or semi-skilled job opportunities in the more productive formal manufacturing sector, and without the necessary education to enter more skilled formal employment in both manufacturing and high-end services, their only alternatives are precarious forms of employment in the gig economy.”
- The issue of job scarcity has long been a part of India's development narrative, not limited to the current administration.
- However, recent changes include the youth bulge, increasing labor force participation rate—particularly among women driven into the workforce by financial distress—the declining share of value added by the informal sector, and the growing capital intensity in production sectors that contribute more to value addition and are labor-intensive by nature
- The consequences of failing to create a sufficient number of more productive jobs, and the resulting deepening labor market duality, are likely to be manifested in various ways, including reduced social mobility and high-income inequality.
- As others have noted, this will determine whether the country follows the path of East Asia or takes the route of Latin America
- The proliferation of smartphones and the internet has facilitated the growth of digital platforms that connect gig workers with customers. Apps and websites have made it easier to find and offer short-term jobs
- India has a large youth population that is tech-savvy and open to flexible work arrangements. The gig economy offers opportunities that appeal to the younger generation seeking autonomy and varied work experiences
- The formal sector has not been able to generate enough jobs to match the growing labor force. As a result, many individuals turn to gig work for income, as it often requires lower barriers to entry compared to traditional employment
- Financial distress and the need for supplementary income have pushed more people towards gig work. This includes individuals who may already have a job but need additional income to meet their financial needs
- The gig economy offers flexibility in work hours and the choice of assignments, which attracts individuals who prefer non-traditional work arrangements over the constraints of full-time employment.
- Companies are increasingly outsourcing tasks to freelancers to reduce costs associated with full-time employees, such as benefits and office space. This shift towards a more flexible workforce model has contributed to the growth of gig work
- The ability to work remotely has opened up international opportunities for gig workers. Indian freelancers can now find work with companies around the world, broadening their employment prospects
- The regulatory framework in India is still catching up with the gig economy, providing a more lenient environment for gig platforms and workers compared to the heavily regulated formal sector
- The gig economy allows workers to leverage diverse skill sets and explore multiple career paths simultaneously. This appeals to individuals looking to diversify their professional experience
- There is growing consumer demand for services that gig workers provide, such as food delivery, ride-hailing, home services, and freelance professional services. This demand fuels the expansion of gig opportunities
| Advantages | Disadvantages |
| Workers can choose their own hours and work location | Gig workers often face uncertain income and job stability. |
| Diverse Opportunities | No Employment Benefits |
| Access to a variety of job types and industries | Absence of benefits like health insurance, retirement plans, and paid leave |
| Increased Income Potential | Income Variability |
| Potential to earn more by taking multiple gigs or high-paying tasks | Earnings can be unpredictable and inconsistent. |
| Opportunity to develop and diversify skill sets. | Many gig workers are not protected by labor laws and regulations |
| Easier entry into the workforce without extensive qualifications. | Limited opportunities for career advancement and long-term growth |
| Greater control over the type of work undertaken and methods of working | Flexibility can lead to overworking and blurred boundaries between work and personal life |
| Ability to work for international clients and companies | Gig workers may miss out on the social aspects and support networks found in traditional workplaces |
| Companies can save on costs related to full-time employees (benefits, office space, etc.). | Potential for gig workers to be underpaid and overworked without proper oversight |
| Can quickly adapt to changing market demands and consumer needs | Limited access to training and professional development resources |
- Gig workers often face unpredictable and inconsistent income, making financial planning difficult
- Gig workers typically do not receive traditional employment benefits such as health insurance, retirement plans, paid leave, and unemployment benefits
- The temporary and project-based nature of gig work means that workers lack job security and can be easily terminated
- There is often a lack of clear legal frameworks to protect gig workers, leading to issues with worker rights, minimum wage enforcement, and job classifications.
- The flexibility of gig work can lead to overworking and difficulty in maintaining a work-life balance, as the lines between personal and professional time can become blurred.
- Gig workers can be vulnerable to exploitation, including low pay, long hours, and lack of proper working conditions, without sufficient oversight and protection
- Gig workers may miss out on the social interactions and support networks that come with traditional workplaces, leading to feelings of isolation and lack of community
- There are limited opportunities for career advancement, professional development, and skill enhancement in the gig economy
- Gig workers often lack access to training and development programs that can help them improve their skills and advance their careers
- Gig workers are usually responsible for managing their own taxes, which can be complex and burdensome without proper knowledge and resources
- Reliance on digital platforms and technology can pose challenges, including the need for constant internet access and the risk of being affected by platform changes or technical issues
- Without formal workplace regulations, gig workers may face unsafe working conditions and lack proper health and safety protections

CERTIFICATION OF FILMS
- The Supreme Court has declared that the ban on the Tamil film Thug Life in Karnataka violates the filmmakers' constitutional right to freedom of speech and expression. The Court instructed the state authorities to uphold the “rule of law” and ensure the film’s unhindered release.
- On June 17, the apex court strongly criticized the “extra-judicial ban” imposed on the film, emphasizing that any movie approved by the Central Board of Film Certification (CBFC) must be allowed to be screened.
- Directed by Mani Ratnam, Thug Life was released nationwide on June 5, except in Karnataka, where its screening was halted due to backlash over a statement by lead actor Kamal Haasan, who claimed that the Kannada language originated from Tamil.
- In light of these events, it becomes important to explore the constitutional framework surrounding freedom of expression and the process of film certification in India
-
Article 19(1)(a), found in Part III of the Indian Constitution, ensures the fundamental right to freedom of speech and expression. This right is enforceable specifically against the state. While certain fundamental rights, such as the abolition of untouchability, prohibition of human trafficking, and bonded labour, apply to both the state and individuals, the right to free speech is directed primarily at government action.
-
This right is exclusively granted to Indian citizens and does not extend to foreign nationals. Article 19(1) outlines the ‘Protection of certain rights regarding freedom of speech, etc.’ It affirms that every citizen has the right:
(a) to express their views freely;
(b) to gather peacefully without weapons;
(c) to form associations or unions;
(d) to move freely within the country;
(e) to live and settle in any part of India;
(f) [omitted];
(g) to practise any profession or to carry out any occupation, trade, or business. -
However, the rights under Article 19(1) are not unrestricted. Article 19(2) specifies circumstances under which the state can impose “reasonable restrictions” on free speech, including concerns related to:
→ National security,
→ International relations,
→ Maintenance of public order,
→ Standards of decency or morality,
→ Judicial integrity (Contempt of Court),
→ Protection of individual reputation (Defamation),
→ Prevention of incitement to crime, and
→ Sovereignty and integrity of India.
| Originally, the right to property was part of Article 19(1)(f) and Article 31, allowing citizens to own and dispose of property, subject to state acquisition for public purposes. However, this was removed as a fundamental right through the 44th Constitutional Amendment in 1978, which eliminated Article 19(1)(f) and Article 31 from the Constitution |
-
In India, films intended for theatrical release, television broadcast, or any form of public exhibition must obtain certification from the Central Board of Film Certification (CBFC).
-
The CBFC classifies films into four main categories:
📌 U: Approved for viewing by all age groups
📌 U/A (UA 7+, UA 13+, UA 16+): Suitable for children with parental supervision, with specific age-based advisories
📌 A: Restricted to adult audiences (18 years and above)
📌 S: Limited to specific professional groups such as scientists, engineers, or doctors
-
The certification process is governed by the Cinematograph Act, 1952, the Cinematograph (Certification) Rules, 1983, and additional guidelines issued by the central government under Section 5B of the Act.
-
Film certification is conducted by an Examining Committee set up by the Regional Officer of the CBFC. The committee reviews the film and provides its recommendations.
-
Certification decisions are made based on either a unanimous or majority opinion within the committee. If there’s a disagreement or a complex issue, it may be escalated to a Revising Committee or resolved by the CBFC Chairperson.
-
The CBFC also has the authority to refuse certification to a film. When filmmakers or producers disagree with CBFC’s verdict—either a certification or a rejection—they have the right to appeal. Previously, such appeals were handled by the Film Certification Appellate Tribunal (FCAT), which often overturned CBFC decisions. However, with the FCAT being dissolved in 2021, appeals must now be made directly to the High Courts.
-
Television programs and serials do not require CBFC certification. Instead, they must comply with the Content and Advertisement Codes outlined in the Cable Television Networks (Regulation) Act, 1995. As violations under this Act are non-cognizable, any legal action must be initiated through a formal complaint by a State Government–authorised officer
-
The Central Board of Film Certification (CBFC) operates as a statutory authority under the Ministry of Information and Broadcasting, overseeing the public screening of films in accordance with the Cinematograph Act of 1952.
-
In India, films must receive CBFC certification before they can be released for public viewing.
-
As per the CBFC's official website, the board is composed of a Chairperson and various non-official members, all of whom are appointed by the Central Government. Its main office is located in Mumbai.
-
The CBFC maintains nine regional offices across the country, situated in Mumbai, Kolkata, Chennai, Bangalore, Thiruvananthapuram, Hyderabad, New Delhi, Cuttack, and Guwahati. These offices are supported by Advisory Panels that assist in reviewing films. The Central Government nominates panel members from diverse professional backgrounds, and their tenure lasts for two years
Article 19(1) of the Indian Constitution guarantees the right to freedom of speech and expression to all citizens. However, this right is subject to reasonable limitations as outlined in Article 19(2), which allows for restrictions in specific circumstances.
Relevant laws governing media and content regulation include:
-
The Cinematograph Act, 1952
-
The Cinematograph (Certification) Rules, 2024
-
Government-issued guidelines under Section 5B of the Cinematograph Act
-
The Cable Television Networks (Regulation) Act, 1995, along with the Cable Television Network Rules, 1994, which include programming and advertising codes
-
The Cigarettes and Other Tobacco Products (Prohibition of Advertisement and Regulation of Trade and Commerce, Production, Supply and Distribution) Act (COTPA), 2003 and associated Rules, 2004
-
The Prevention of Cruelty to Animals Act
-
The Emblems and Names (Prevention of Improper Use) Act, 1950
-
The Prevention of Insults to National Honour Act, 1971
-
The Drugs and Magic Remedies (Objectionable Advertisements) Act
-
The Scheduled Castes and the Scheduled Tribes (Prevention of Atrocities) Act, 1989
-
The Indecent Representation of Women (Prohibition) Act, 1986
-
The Protection of Children from Sexual Offences (POCSO) Act, 2012, among others
-
The government has recently introduced a system of age-specific film certifications to encourage viewing that aligns with the viewer's age, especially for categories requiring parental supervision.
-
Through a gazette notification, the Ministry of Information and Broadcasting amended the rules first issued in December 1991, which outline the criteria for approving films for public screening.
-
The updated rules empower the Central Board of Film Certification (CBFC) to grant clearance for unrestricted public exhibition of films, while also indicating suitable age groups based on the film’s content.
-
As per the notification, content deemed appropriate for children aged 7 and above—but still requiring parental guidance for those under 7—will be rated as ‘U/A 7+’. Similarly, content suitable for children 13 and older but needing supervision for those below that age will receive a ‘U/A 13+’ rating. For children 16 and above, with guidance for younger viewers, the classification will be ‘U/A 16+’

GREEN INDIAN MISSION
.png)
-
The Green India Mission (GIM), launched in 2014, is one of the eight key missions under India’s National Action Plan on Climate Change (NAPCC). It primarily aims to address climate change by expanding forest and tree cover, and by restoring degraded forests and ecosystems.
-
The mission also focuses on enhancing the livelihoods of communities that depend on forest resources. A major goal of GIM is to bring 5 million hectares under new forest and tree cover and to enhance the quality of forest cover on another 5 million hectares.
-
GIM activities are prioritized in states based on factors such as ecological vulnerability, carbon sequestration potential (the ability of vegetation to capture and store carbon through photosynthesis), and the extent of land and forest degradation.
-
Under the revised plan, the mission emphasizes restoring vulnerable landscapes using region-specific sustainable practices. This includes targeted ecological restoration in significant mountain regions like the Aravalli hills, the Western Ghats, and the Himalayan range, as well as critical mangrove areas. For instance, GIM efforts will align with the Aravalli Green Wall initiative recently launched by the central government.
-
The updated mission document, using projections from the Forest Survey of India (FSI), estimates that India could create a carbon sink of approximately 3.39 billion tonnes by carrying out these restoration activities. Achieving this would involve increasing forest and tree cover across around 24.7 million hectares
As highlighted by the Convention on Combating Desertification, both natural phenomena and human activities contribute to the degradation of land, turning fertile areas into desert-like regions. Rapid population growth has escalated the need for food, water, livestock feed, and various ecosystem services. In response, humans have resorted to deforestation, excessive use of agrochemicals, intensive farming, and overextraction of groundwater. These practices have significantly harmed the land’s health and productivity.
Natural factors, such as rising global temperatures, have led to more frequent and intense droughts, while erratic weather patterns continue to place additional stress on land resources.
Primary Drivers of Land Degradation and Desertification:
-
Unsustainable Farming Methods
-
Continuous cropping without allowing land to recover
-
Shifting cultivation with insufficient fallow periods
-
Heavy reliance on chemical fertilizers
-
-
Land Conversion for Human Use
-
Deforestation to clear land for agriculture or development
-
Unregulated urban expansion
-
-
Loss of Vegetation and Forest Cover
-
Overgrazing by livestock
-
Excessive harvesting of fuelwood
-
Poor forest management practices
-
Incidence of forest fires
-
-
Impact of Drought on Land Quality
-
Lack of vegetative cover worsens drought impacts and disrupts local water cycles
-
-
Inefficient Water Use
-
Ineffective irrigation methods
-
Excessive withdrawal of groundwater resources
-
-
Land forms a critical component of ecosystems, and maintaining its health and productivity is essential for preserving ecological stability. In this context, restoring degraded land plays a key role.
-
As defined by the United Nations Convention to Combat Desertification (UNCCD), land restoration refers to the ecological process of bringing degraded landscapes back to a state that supports the well-being of humans, wildlife, and plant life.
-
Reviving land ecosystems contributes to environmental protection, supports economic growth, reduces the risk of disasters like floods, enhances soil fertility, and boosts food production. In essence, restoring land is fundamental for sustaining the planet, adapting to drought conditions, and ensuring food security for an expanding global population
-
The 18th edition of the India State of Forest Report (ISFR-2023) was unveiled by Environment Minister Bhupender Yadav in December at the Forest Research Institute, Dehradun. Published every two years, the ISFR uses satellite imagery to assess the country’s forest cover.
-
India has now crossed the 25% green cover benchmark, with 8,27,357 sq km (25.17%) of its total area covered by forests (21.76%) and trees (3.41%). Of this, 4,10,175 sq km is categorized as dense forest.
-
Between 2021 and 2023, forest cover expanded by 156.41 sq km, bringing the total forested area to 21.76% of the country's geographical area—an increase of just 0.05% since the last report. The overall forested land now stands at 7,15,342.61 sq km.
-
Notably, tree cover saw the most significant growth, rising from 2.91% in 2021 to 3.41% in 2023—an addition of 1,285.4 sq km.
-
For the first time, forest cover in the Western Ghats was assessed. It revealed that the eco-sensitive zone designated by the central government has lost 58.22 sq km of forest since 2013. Additionally, mangrove cover saw a decline of 7.43 sq km compared to 2021.
-
Chhattisgarh registered the highest increase in forest and tree cover (683.62 sq km), followed by Uttar Pradesh (559.19 sq km), Odisha (558.57 sq km), and Rajasthan (394.46 sq km). In contrast, the largest reductions were observed in Madhya Pradesh (612.41 sq km), Karnataka (459.36 sq km), Ladakh (159.26 sq km), and Nagaland (125.22 sq km).
-
In terms of total forest and tree cover, Madhya Pradesh leads with 85,724 sq km, followed by Arunachal Pradesh with 67,083 sq km, and Maharashtra with 65,383 sq km

NUCLEAR NON-PROLIFERATION TREATY
- Established in 1968 and coming into effect in 1970, this global agreement was designed to curb the spread of nuclear arms and technologies, encourage collaboration on the peaceful application of nuclear energy, and advance nuclear disarmament.
- After World War II concluded in 1945 with the U.S. detonating atomic bombs over Japan, major powers began developing nuclear arsenals, even as parallel initiatives sought to control the dissemination of nuclear know-how.
- One such effort emerged in 1953 with the U.S. launching the Atoms for Peace program under President Dwight D. Eisenhower. This initiative paved the way for the creation of the International Atomic Energy Agency (IAEA).
- In a landmark address, Eisenhower emphasized that America’s goal went beyond merely limiting nuclear weapons. He advocated for repurposing atomic energy for constructive, peaceful purposes, rather than just eliminating its military applications.
- In a 1981 article, international affairs scholar Joseph Nye highlighted that the initiative’s most impactful legacy was the establishment of a safeguards regime. This system required non-nuclear-armed states to submit detailed reports on their civilian nuclear programs and allowed for international inspections to verify that nuclear material was not diverted for weaponization.
- According to the treaty, nuclear-weapon states are defined as those that had detonated a nuclear device before January 1, 1967—specifically the U.S., U.K., France, the Soviet Union (now Russia), and China.
- Currently, 191 countries are parties to the treaty. India, which conducted its first nuclear test in 1974, has not signed it and instead emphasizes the need for universal and non-discriminatory approaches to nuclear non-proliferation.
- Critics argue that the treaty is biased in favor of the five permanent UN Security Council members, given the arbitrary cut-off date that grants them nuclear status.
- Pakistan has also declined to join the treaty. Israel, though widely believed to possess nuclear arms, has neither confirmed this nor become a signatory. North Korea joined in 1985 but withdrew in 2003 after revelations about its uranium enrichment program and the subsequent expulsion of IAEA inspectors
- Among the 11 provisions of the treaty, one outlines the process for a country to exit. Article 10 specifically allows for withdrawal, stating that any member, while exercising its sovereign rights, may leave the treaty if it determines that extraordinary circumstances related to the treaty’s subject matter have endangered its core national interests.
- The withdrawing nation must give three months' advance notice to all treaty parties and the United Nations Security Council (UNSC), including an explanation of the exceptional events prompting its decision.
- Iran became a party to the treaty in 1970, almost a decade before it transitioned into a theocratic state following the Islamic Revolution. Recently, for the first time in nearly two decades, the International Atomic Energy Agency’s (IAEA) 35-member Board of Governors—which includes countries like the P5, India, Japan, Ukraine, and Bangladesh—accused Iran of violating its non-proliferation commitments.
- The resolution passed by the board pointed to Iran’s repeated failure since 2019 to provide adequate and timely cooperation with the IAEA, particularly regarding nuclear materials and activities at undeclared sites. Iran, however, insisted that it has consistently fulfilled its safeguards obligations.
- Leaving the treaty presents two major risks: first, Iran would no longer be subject to the IAEA’s routine inspections and oversight; second, its exit could embolden other nations to abandon the treaty as well, undermining global efforts to control nuclear proliferation.
- According to Bloomberg’s analysis of IAEA data, agency inspectors visited Iranian nuclear sites at a rate of 1.4 times per day on average last year—an access level that would cease if Iran withdrew.
- Nonetheless, staying within the NPT does not automatically indicate a country has no interest in developing nuclear arms, as cases like North Korea have shown. Although Iranian leaders have repeatedly stated they do not intend to pursue nuclear weapons, shifting geopolitical realities in the Middle East leave room for uncertainty.
- Despite its limitations, scholars such as Joseph Nye argue that the treaty has played a valuable role in at least slowing the global spread of nuclear weapons
The IAEA plays a critical role in enforcing the Nuclear Non-Proliferation Treaty (NPT) by monitoring compliance through regular inspections, especially in non-nuclear-weapon states that agree to open their civilian nuclear programs to scrutiny.
The IAEA is governed by a Board of Governors (35 member states) and a General Conference, and its reports are influential in shaping global nuclear policy
Notable contributions:
-
Verification missions in Iran, North Korea, and Iraq.
-
Coordination of global nuclear safety after incidents like Chernobyl (1986) and Fukushima (2011).
-
Promotion of nuclear medicine and radiation therapies in developing countries.
-
The NPT recognizes only five countries as nuclear-weapon states (the U.S., Russia, China, the U.K., and France) — those that tested nuclear weapons before January 1, 1967.
-
India conducted its first nuclear test in 1974 (Smiling Buddha) and was thus excluded from this group.
-
This arbitrary cut-off date effectively created two classes of states: nuclear "haves" and "have-nots." India argues that this undermines the principle of equality in international law
-
While the NPT obliges non-nuclear weapon states to not acquire nuclear weapons, it only vaguely commits the nuclear powers to pursue disarmament.
-
India criticizes the treaty for lacking a concrete timeline for global nuclear disarmament, making it imbalanced.
-
India sees possession of nuclear weapons as essential for strategic autonomy and national security, especially given its geopolitical environment (with nuclear-armed neighbors like China and Pakistan).
-
Signing the NPT as a non-nuclear state would have required India to give up its nuclear weapons capability, which it sees as unacceptable for its national security
-
In 2008, India secured a civil nuclear deal with the U.S. and a waiver from the Nuclear Suppliers Group (NSG), despite not signing the NPT.
-
This demonstrated growing global acceptance of India's nuclear status and its responsible record on non-proliferation

RADIO FREQUENCY IDENTIFICATION (RFID)
-
FASTag is a digital toll payment mechanism jointly overseen by the National Payments Corporation of India (NPCI) and the National Highways Authority of India (NHAI). The FASTag is typically affixed to a vehicle's windshield and was initially introduced in 2014 as a test initiative. It became compulsory for toll collection across all national highways in 2021.
-
The system operates using Radio Frequency Identification (RFID) technology, which enables interaction between the FASTag and electronic sensors at toll booths. As a vehicle passes through a toll gate, the toll fee is automatically debited from the associated bank account or digital wallet linked to the FASTag.
-
RFID is a form of wireless identification that comprises tags and reading devices. It uses radio waves to relay details such as identification or status of an item or person to a nearby reader—either handheld or installed at fixed locations like structures or poles. These tags can include encrypted data, unique serial numbers, or brief descriptors. Some tags, particularly those used in the aviation sector, can store large volumes of data.
-
RFID tags are categorized into three types: passive, semi-passive, and active. Active RFID tags have their own power source, typically a battery, allowing them to send signals periodically or when they detect a nearby reader. In contrast, passive RFID tags lack a power source and rely on the electromagnetic energy emitted by the reader to function. These passive tags are the type employed in the FASTag system. Semi-passive tags have internal circuitry and power, but still depend on the reader’s signal to respond.
-
RFID systems function through an antenna and a microchip, which together communicate with a reader by emitting radio signals. These systems operate at various frequency bands including low (LF), high (HF), and ultra-high frequencies (UHF). The signals received from the tags are then decoded into usable information by a computer system
ANPR FASTag System (AFS) is an advanced toll collection mechanism that integrates Automated Number Plate Recognition (ANPR) technology with the existing FASTag infrastructure to enable seamless and contactless toll payment.
Unlike traditional FASTag systems, where RFID tags on a vehicle's windshield are scanned by sensors at toll plazas, AFS uses high-resolution cameras to automatically read vehicle registration numbers. These cameras are equipped with software that captures and processes images of license plates as vehicles approach toll booths or designated gantries.
The ANPR system cross-verifies the vehicle’s registration details with the FASTag database, which includes the vehicle’s number and linked payment account. Once a match is found, the toll amount is automatically deducted from the corresponding FASTag wallet or bank account—without requiring a physical RFID scan.
Key Features:
-
Contactless Tolling: Vehicles don’t need to slow down or stop for RFID scanning.
-
No Tag Dependency: Even if the FASTag is damaged or unreadable, the toll can still be collected using the vehicle’s number plate.
-
Real-time Verification: AFS enhances enforcement by checking vehicle compliance (e.g., tag validity, blacklisted status) in real-time.
-
Reduced Congestion: Faster vehicle movement through toll plazas due to camera-based number recognition.
-
NavIC (Navigation with Indian Constellation), officially known as the Indian Regional Navigation Satellite System (IRNSS), is a satellite-based navigation network developed by the Indian Space Research Organisation (ISRO). It is designed to function independently and consists of seven satellites. Of these, three are positioned in geostationary orbit, while the remaining four occupy inclined geosynchronous orbits, catering to both civilian and military requirements.
-
The concept of having India’s own satellite navigation system emerged after the 1999 Kargil conflict, during which India’s defence forces were denied access to the US-based GPS. In response, India launched its first satellite under this initiative, IRNSS-1A, on July 1, 2013.
-
With the launch of IRNSS-1G on April 28, 2016, the seventh satellite in the series, ISRO declared the IRNSS constellation complete. However, from mid-2016 onward, several satellites experienced failures due to malfunctioning rubidium atomic clocks. Out of the 11 satellites launched under the ₹2,250 crore NavIC project (including replacements), only five are currently fully functional, according to ISRO.
-
NavIC delivers two distinct services: the Standard Positioning Service (SPS) for general and commercial users, and the Restricted Service (RS), which is encrypted and intended solely for military and strategic applications. These services cover the Indian subcontinent and surrounding areas.
-
Although global satellite systems such as GPS (USA), GLONASS (Russia), Galileo (EU), BeiDou (China), and QZSS (Japan) are available, India pursued its own navigation system to ensure uninterrupted and reliable service, especially for defence operations where strategic autonomy is crucial.
- RFID (Radio Frequency Identification) technology has become increasingly prevalent across numerous industries due to its ability to automatically identify and track objects, animals, and people using electromagnetic fields. Here are the key applications:
- RFID tags enable real-time inventory tracking, reducing stockouts and overstocking. Major retailers use RFID to monitor product movement from warehouses to store shelves, automatically updating inventory systems. This technology also powers anti-theft systems and enables faster checkout processes through bulk scanning
- The technology provides end-to-end visibility in supply chains, allowing companies to track shipments, monitor temperature-sensitive goods, and verify authenticity. RFID helps optimize warehouse operations through automated sorting and reduces manual scanning errors in distribution centers
- Hospitals use RFID for patient identification, medication tracking, and equipment management. The technology helps prevent medical errors by ensuring patients receive correct medications and dosages. It also tracks expensive medical equipment and monitors the location of patients, particularly those with conditions like dementia.
- RFID-enabled key cards and badges control building access, replacing traditional keys. The technology provides detailed audit trails of who accessed which areas and when, enhancing security in corporate buildings, government facilities, and residential complexes
- Electronic toll collection systems like E-ZPass use RFID to automatically charge vehicles passing through toll booths. Public transportation systems employ RFID in contactless payment cards for buses, trains, and subways.

HYDRAULIC SYSTEMS
- Have you ever noticed how cranes lift heavy materials, excavators dig and move soil, or how aircraft landing gear extends and retracts? Despite their different functions, these machines all share a common mechanism: hydraulics. In each case, energy—whether from an electric motor or a combustion engine—is transformed into versatile mechanical motion through hydraulic systems.
- Hydraulic systems operate on Pascal’s law, named after the 17th-century French scientist Blaise Pascal. The law explains that when pressure is applied to a fluid that cannot be compressed, that pressure is distributed uniformly throughout the fluid. In simple terms, pressure refers to the force applied per unit area.
- In practice, when a force is exerted on the fluid in a hydraulic system, it creates pressure that spreads equally in all directions. This principle allows a relatively small force applied to a smaller area to produce a much greater force at a larger surface, as shown in illustrative examples.
- For instance, applying a minor force at one end of the system can result in a significantly amplified force at the other end by merely increasing the area where the pressure is applied—without altering the pressure itself. This is one of the most basic applications of hydraulics, but the technology is capable of much more than just lifting objects.
- Hydraulic systems offer several benefits over traditional mechanical energy transmission methods. These include smoother operation, a higher power-to-weight ratio, more effective heat management, better control, and greater precision
3. What are the parts of hydraulic systems?
Every hydraulic system typically consists of six core elements:
-
Pumps – These convert mechanical input energy into hydraulic pressure and establish fluid flow.
-
Pipes – These transport hydraulic fluid to the application points and return it to the reservoir.
-
Valves – These manage the flow rate and direction of pressurized fluid.
-
Actuators (linear or rotary) – These execute the mechanical output by converting hydraulic energy into motion.
-
Reservoir (with filters) – This stores the hydraulic fluid.
-
Sensors and switches – These are integrated as needed for operational efficiency or safety.
Among these, the essential active components are the pumps, valves, actuators, and in some cases, the sensors or switches. Components like reservoirs, filters, and piping mainly serve to store and transport the hydraulic fluid and do not participate directly in the dynamic operation.
In large-scale systems, oil cooling mechanisms are often added to counteract heat generated during prolonged use. In contrast, in colder climates, preheating devices are included to reduce oil viscosity before system startup.
Hydraulic pumps come in various forms—gear, axial piston, or variable displacement types—chosen according to the pressure and flow rate requirements of the specific application. These pumps may be powered either by electric motors or connected directly to combustion engines using a power take-off system.
Valves fall into three primary categories based on their function: regulating flow, directing fluid path, and controlling pressure. In simple setups, these valves may be operated manually, while more advanced systems use electrically controlled valves.
Actuators are critical for delivering mechanical work at the point of application. The most widely used type is the linear actuator or hydraulic cylinder, which operates using a sliding rod inside a cylindrical housing. These rods are often chrome-plated and easily identifiable on equipment like cranes or excavators. The force output depends on the fluid pressure, speed is influenced by the flow rate, and direction is determined by the direction of fluid flow.
Rotary actuators, or hydraulic motors, provide rotational movement instead of linear motion. They are used in systems where circular motion is required, such as powering a winch. Here, the fluid’s flow rate, pressure, and direction control the motor’s speed, torque, and rotation direction, respectively.
4. How do hydraulic systems work?
Hydraulics is based on Pascal’s Law, which states:
“When pressure is applied to an incompressible fluid in a confined space, it is transmitted equally in all directions.”
This means that if you apply a small force to a fluid in one part of the system, it can create a larger force elsewhere, depending on the surface areas involved
Key Components and Their Roles
A typical hydraulic system has the following main parts:
-
Pump: Converts mechanical energy (from a motor or engine) into hydraulic energy by pushing fluid into the system.
-
Reservoir/Tank: Stores the hydraulic fluid (usually oil) and also helps in cooling and filtering.
-
Valves: Control the direction, pressure, and flow of the fluid.
-
Actuators:
-
Linear actuators (hydraulic cylinders) produce straight-line (push/pull) motion.
-
Rotary actuators (hydraulic motors) produce rotational motion.
-
-
Pipes and Hoses: Transport the pressurized fluid between components.
-
Filters and Sensors: Clean the oil and monitor system parameters
5. Applications of the hydraulic system
- Hydraulic systems are now widely used across diverse sectors such as agriculture, waste disposal, automation, and even renewable energy like wind turbines.
- They serve both mobile machinery—such as cranes and excavators that operate on tracks or wheels—and stationary equipment, including hydraulic presses, molding machines, and windmills, where the core system remains fixed.
- Globally, the hydraulics industry is valued between $45–50 billion and continues to expand steadily.
- With advancements in electronics and increased electrification, hydraulic systems are evolving to integrate modern technologies. Today’s systems often feature sensors that monitor variables like motion, temperature, pressure, fluid flow, and even contamination levels in oil.
- These enhancements not only aim to boost safety but also help gather data that improves system performance and supports predictive maintenance.
- However, hydraulic systems are not without limitations. Their current overall energy efficiency—from engine input to final mechanical output—hovers around 30–40%.
- Engineers and researchers are actively working to increase this efficiency while also addressing environmental concerns.
- Despite ongoing efforts to replace hydraulics with electrical alternatives, such substitutions are mostly effective only in smaller-scale applications. For larger, more complex systems, hydraulics continues to offer unmatched advantages
