LANDSLIDES
1. Context
- The recent cases of land subsidence in Joshimath, Uttarakhand, captured the spotlight.
- On June 29, 2022, at least 79 people were killed in a landslide in the Noney district of Manipur.
- The risk analysis in the report was based on the density of human and livestock populations, which indicates the impacts on people due to these landslides.
- The disaster in Kedaranath in 2013 and the landslides caused by the devastating Sikkim earthquake in 2011 are also included in this atlas.
Between 1988 and 2022, the maximum number of landslides 12, 385 recorded in Mizoram.
Uttarakhand followed it at 11, 219, Tripura at 8, 070, Arunachal Pradesh at 7, 689, and Jammu and Kashmir at 7,280. Kerala saw 6,039, Manipur 5,494 and Maharashtra recorded 5, 112 incidents of landslides.
|
- Globally, landslides rank third in terms of deaths among natural disasters.
- However, deforestation due to unplanned urbanisation and human greed increases the risk of such incidents.
- In 2006, about 4 million people were affected by landslides, including a large number of Indians.
- India is among the four major countries where the risk of landslides is the highest; it added. If we look at the figures, about 0.42 million square kilometres in the country are prone to landslides, which is 12.6 per cent of the total land area of the country.
- However, the figure does not include snow-covered areas. Around 0.18 million sq km of landslide-prone areas in the country are in North East Himalayas, including Darjeeling and Sikkim Himalayas.
- Of the rest, 0.14 million sq km falls in North West Himalaya (Uttarakhand, Himachal Pradesh and Jammu and Kashmir); 90, 000 sq km in the Western Ghats and Konkan hills (Tamil Nadu, Kerala, Karnataka, Goa and Maharashtra) and 10, 000 sq km in Eastern Ghats of Aruku in Andhra Pradesh.
3. Reasons for landslides
- Sudden heavy rains due to climate change are also increasing landslides. Around 73 per cent of landslides in the Himalayan region are attributed to heavy rains and reduced water-absorbing capacity of the soil.
- Global climate change is causing heavy rainfall that erodes steep slopes with loose soil found in a 2020 study by the Indian Institute of Technology in Delhi.
- Therefore, the increasing number of landslides can no longer be termed as just natural disasters, as human actions have also played a major role in it.
- Uttakarkhand, Kerala, Jammu and Kashmir, Mizoram, Tripura, Nagaland and Arunachal Pradesh reported the highest number of landslides during 1998 – 2022
- Mizoram topped the list, recording 12,385 landslide events in the past 25 years, of which 8,926 were recorded in 2017 alone
- Likewise, 2,071 events of the total 2,132 landslides reported in Nagaland during this period occurred during the 2017 monsoon season
- Manipur, too, showed a similar trend, wherein 4,559 out of 5,494 landslide events were experienced during the rainy season of 2017, Of the total 690, Tamil Nadu suffered 603 landslide events in 2018 alone
- Among all these states, an alarming situation is emerging from Uttarakhand and Kerala

- While Uttarakhand’s fragility was recently exposed during the land subsidence events reported from Joshimath since January, this Himalayan state has experienced the second highest number (11,219) of landslides since 1998, all events since occurring post 2000
- The year-wise number of landslide events in the state is: 2003 (32), 2010 (307), 2012 (473), 2013 (6,610), 2017 (1), 2021 (329) and 2022 (1)
- The number of districts with the maximum landslide exposure are in Arunachal Pradesh (16), Kerala (14), Uttarakhand and Jammu and Kashmir (13 each), Himachal Pradesh, Assam and Maharashtra (11 each), Mizoram (8) and Nagaland (7)
- Kerala has been consistently reporting massive landslides since it suffered the century’s worst floods in 2018
- The year-wise landslide events here are 2018 (5,191), 2019 (756), 2020 (9) and 2021 (29).
- From the events and images obtained, the NRSC ranked Rudraprayag in Uttarakhand at the top of 147 vulnerable districts
- It has the highest landslide density in the country, along with having the highest exposure to total population and number of houses

GROSS DOMESTIC PRODUCT (GDP)
There are three primary ways to calculate GDP:
-
Production Approach (GDP by Production): This approach calculates GDP by adding up the value-added at each stage of production. It involves summing up the value of all final goods and services produced in an economy.
-
Income Approach (GDP by Income): This approach calculates GDP by summing up all the incomes earned in an economy, including wages, rents, interests, and profits. The idea is that all the income generated in an economy must ultimately be spent on purchasing goods and services.
-
Expenditure Approach (GDP by Expenditure): This approach calculates GDP by summing up all the expenditures made on final goods and services. It includes consumption by households, investments by businesses, government spending, and net exports (exports minus imports).
3. Measuring GDP
GDP can be measured in three different ways:
-
Nominal GDP: This is the raw GDP figure without adjusting for inflation. It reflects the total value of goods and services produced at current prices.
-
Real GDP: Real GDP adjusts the nominal GDP for inflation, allowing for a more accurate comparison of economic performance over time. It represents the value of goods and services produced using constant prices from a specific base year.
-
GDP per capita: This is the GDP divided by the population of a country. It provides a per-person measure of economic output and can be useful for comparing the relative economic well-being of different countries.
The GDP is a useful measure of economic health, but it has some limitations. For example, it does not take into account the distribution of income in an economy. It also does not take into account the quality of goods and services produced.
Despite its limitations, the GDP is a widely used measure of economic health. It is used by economists, policymakers, and businesses to track the performance of an economy and to make decisions about economic policy
4. Gross Value Added (GVA)
Gross Value Added (GVA) is a closely related concept to Gross Domestic Product (GDP) and is used to measure the economic value generated by various economic activities within a country. GVA represents the value of goods and services produced in an economy minus the value of inputs (such as raw materials and intermediate goods) used in production. It's a way to measure the contribution of each individual sector or industry to the overall economy.
GVA can be calculated using the production approach, similar to one of the methods used to calculate GDP. The formula for calculating GVA is as follows:
GVA = Output Value - Intermediate Consumption
Where:
- Output Value: The total value of goods and services produced by an industry or sector.
- Intermediate Consumption: The value of inputs used in the production process, including raw materials, energy, and other intermediate goods.
Gross Domestic Product (GDP) and Gross National Product (GNP) are both important economic indicators used to measure the size and health of an economy, but they focus on slightly different aspects of economic activity and include different factors. Here are the key differences between GDP and GNP:
-
Definition and Scope:
- GDP: GDP measures the total value of all goods and services produced within a country's borders, regardless of whether the production is done by domestic or foreign entities. It only considers economic activities that take place within the country.
- GNP: GNP measures the total value of all goods and services produced by a country's residents, whether they are located within the country's borders or abroad. It takes into account the production of residents, both domestically and internationally.
-
Foreign Income and Payments:
- GDP: GDP does not consider the income earned by residents of a country from their economic activities abroad, nor does it account for payments made to foreigners working within the country.
- GNP: GNP includes the income earned by a country's residents from their investments and activities abroad, minus the income earned by foreign residents from their investments within the country.
-
Net Factor Income from Abroad:
- GDP: GDP does not account for net factor income from abroad, which is the difference between income earned by domestic residents abroad and income earned by foreign residents domestically.
- GNP: GNP includes net factor income from abroad as part of its calculation.
-
Foreign Direct Investment:
- GDP: GDP does not directly consider foreign direct investment (FDI) flowing into or out of a country.
- GNP: GNP considers the impact of FDI on the income of a country's residents, both from investments made within the country and from investments made by residents abroad.
-
Measurement Approach:
- GDP: GDP can be calculated using three different approaches: production, income, and expenditure approaches.
- GNP: GNP is primarily calculated using the income approach, as it focuses on the income earned by residents from their economic activities.

HEATWAVE
1. Context
2. What is a Heat Wave?
- A heatwave is a period of abnormally high temperatures, a common phenomenon in India during the months of May-June and in some rare cases even extends till July.
- Indian Meteorological Department (IMD) classifies heat waves according to regions and temperature ranges. As per IMD, the number of heatwave days in India has increased from 413 over 1981-1990 to 600 over 2011-2020.
- This sharp rise in the number of heatwave days has resulted due to the increasing impact of climate change.
- The last three years have been La Niña years, which has served as a precursor to 2023 likely being an El Niño year. (The El Niño is a complementary phenomenon in which warmer water spreads westeast across the equatorial Pacific Ocean.)
- As we eagerly await the likely birth of an El Niño this year, we have already had a heat wave occur over northwest India.
- Heat waves tend to be confined to north and northwest India in El Niño years.

3. How do Heat waves Occur?
- Heat waves are formed for one of two reasons warmer air is flowing in from elsewhere or it is being produced locally.
- It is a local phenomenon when the air is warmed by higher land surface temperature or because the air sinking down from above is compressed along the way, producing hot air near the surface.
- First of all, in spring, India typically has air flowing in from the westnorthwest. This direction of airflow is bad news for India for several reasons.
- Likewise, air flowing in from the northwest rolls in over the mountains of Afghanistan and Pakistan, so some of the compression also happens on the leeward side of these mountains, entering India with a bristling warmth.
- While air flowing over the oceans is expected to bring cooler air, the Arabian Sea is warming faster than most other ocean regions.
- Next, the strong upper atmospheric westerly winds, from the Atlantic Ocean to India during spring, control the near-surface winds.
- Any time winds flow from the west to the east, we need to remember that the winds are blowing faster than the planet which also rotates from west to east.
- The energy to run past the earth near the surface, against surface friction, can only come from above. This descending air compresses and warms up to generate some heat waves.
4. Impacts of heat waves in India
- The frequent occurrence of heat waves also adversely affects different sectors of the economy.
- For instance, the livelihood of poor and marginal farmers is negatively impacted due to the loss of working days.
- Heatwaves also have an adverse impact on daily wage workers' productivity, impacting the economy.
- Crop yields suffer when temperatures exceed the ideal range.
- Farmers in Haryana, Punjab, and Uttar Pradesh have reported losses in their wheat crop in the past rabi season. Across India, wheat production could be down 6-7% due to heat waves.
- Mortality due to heat waves occurs because of rising temperatures, lack of public awareness programs, and inadequate long-term mitigation measures.
- According to a 2019 report by the Tata Center for Development and the University of Chicago, by 2100 annually, more than 1.5 million people will be likely to die due to extreme heat caused by climate change.
- The increased heat wave will lead to an increase in diseases like diabetes, circulatory and respiratory conditions, as well as mental health challenges.
-
The concurrence of heat and drought events is causing crop production losses and tree mortality. The risks to health and food production will be made more severe by the sudden food production losses exacerbated by heat-induced labor productivity losses.These interacting impacts will increase food prices, reduce household incomes, and lead to malnutrition and climate-related deaths, especially in tropical regions.
5. How does air mass contribute to heat waves?
- The other factors that affect the formation of heat waves are the age of the air mass and how far it has traveled.
- The north northwestern heatwaves are typically formed with air masses that come from 800-1600 km away and are around two days old.
- Heat waves over peninsular India on the other hand, arrive from the oceans, which are closer (around 200-400km) and are barely a day old. As a result, they are on average less intense.
6. Way ahead for Heat waves
- Identifying heat hot spots through appropriate tracking of meteorological data and promoting timely development and implementation of local Heat Action Plans with strategic inter-agency coordination, and a response that targets the most vulnerable groups.
- Review existing occupational health standards, labor laws, and sectoral regulations for worker safety in relation to climatic conditions.
- Policy intervention and coordination across three sectors health, water, and power are necessary.
- Promotion of traditional adaptation practices, such as staying indoors and wearing comfortable clothes.
- Popularisation of simple design features such as shaded windows, underground water storage tanks, and insulating house materials.
- Advance implementation of local Heat Action Plans, plus effective inter-agency coordination is a vital response that the government can deploy in order to protect vulnerable groups.

NATIONAL GREEN TRIBUNAL
1. Context
2. What is National Green Tribunal (NGT)?
- The National Green Tribunal (NGT) is a specialized judicial body established in India to handle cases related to environmental protection and conservation.
- It was established under the National Green Tribunal Act, of 2010, and its primary objective is to effectively and expeditiously address environmental disputes and promote sustainable development.
-
With the establishment of the NGT, India became the third country in the world to set up a specialized environmental tribunal, only after Australia and New Zealand, and the first developing country to do so.
-
NGT is mandated to make disposal of applications or appeals finally within 6 months of the filing of the same.
-
The NGT has five places of sittings, New Delhi is the Principal place of sitting, and Bhopal, Pune, Kolkata and Chennai are the other four.
3. Structure of the National Green Tribunal (NGT)
- Chairperson: The NGT is headed by a full-time Chairperson who is a retired judge of the Supreme Court of India. The Chairperson is responsible for the overall administration and functioning of the tribunal.
- Judicial Members: The NGT consists of judicial members who are retired judges of either the Supreme Court or a High Court. These members have extensive legal knowledge and experience in handling environmental matters.
- Expert Members: The tribunal also includes expert members who possess expertise in areas such as environmental science, ecology, hydrology, and forestry. These members provide valuable technical insights and guidance in the resolution of environmental disputes.
- The NGT is organized into multiple benches located across different regions of India. These benches are responsible for hearing cases specific to their respective jurisdictions. Each bench is headed by a judicial member and consists of one or more expert members, as required.
4. What are the Important Landmark Judgements of NGT?
The National Green Tribunal (NGT) has delivered several landmark judgments that have had a significant impact on environmental protection and conservation in India. Here are some of the important landmark judgments delivered by the NGT:
- Vardhaman Kaushik v. Union of India (2013): This case dealt with the issue of groundwater depletion due to illegal extraction by industries in Uttar Pradesh. The NGT directed the closure of industries that were extracting groundwater without proper permissions and ordered the payment of compensation for environmental damage caused.
- Alembic Pharmaceuticals Ltd. v. Rohit Prajapati & Ors. (2014): In this case, the NGT ordered the closure of an industrial unit in Gujarat for releasing untreated effluents into a water body, causing pollution and harm to the environment and public health.
- M.C. Mehta v. Union of India (2014): The NGT issued a landmark judgment in this case regarding the pollution of the Yamuna River. It directed several measures to clean and rejuvenate the river, including the establishment of sewage treatment plants and the regulation of industries contributing to pollution.
- Subhash Chandra Sharma v. Union of India (2015): This case focused on the issue of air pollution caused by solid waste burning in open areas. The NGT imposed a ban on burning waste in open spaces and directed municipal authorities to take measures to manage waste effectively.
- Raghu Nath Sharma v. State of Himachal Pradesh (2016): The NGT ordered the closure of illegal hotels and structures in the eco-sensitive Rohtang Pass area of Himachal Pradesh to protect the fragile Himalayan ecosystem.
- Yamuna Muktikaran Abhiyan v. Union of India (2017): This case dealt with the rejuvenation of the Yamuna River and led to the NGT issuing directions to clean and restore the river, including measures to prevent encroachments and pollution.
- M.C. Mehta v. Union of India (2017): The NGT banned the use of disposable plastic in Delhi and the National Capital Region (NCR) and directed authorities to take steps to prevent the use and sale of such plastic.
- Shailesh Singh v. Hotel Holiday Regency (2019): In this case, the NGT imposed heavy fines on a hotel in Shimla, Himachal Pradesh, for causing air pollution by running diesel generators without proper emission control measures.
- Subhash Chandran vs. Tamil Nadu Pollution Control Board (2020): This judgment highlighted the importance of safeguarding coastal areas and wetlands from unauthorized construction and development activities, emphasizing the need for stringent environmental norms.
- In Re: Report by Comptroller and Auditor General of India (2021): The NGT directed the formulation of guidelines for the regulation of groundwater extraction and management to prevent overexploitation and depletion.
5. What is a dissolved oxygen level?
- Dissolved oxygen (DO) level refers to the concentration of oxygen gas (O2) that is dissolved in a liquid, typically water.
- It is a crucial parameter in aquatic ecosystems as it directly affects the survival and well-being of aquatic organisms.
- In natural water bodies like lakes, rivers, and oceans, oxygen dissolves from the atmosphere through processes such as diffusion and aeration.
- Aquatic plants, algae, and phytoplankton also contribute to the production of oxygen through photosynthesis. However, the level of dissolved oxygen can fluctuate based on various factors, including temperature, altitude, water flow, pollution, and organic matter decomposition.
- Dissolved oxygen is essential for aquatic organisms because they rely on it for their respiration process, similar to how animals breathe oxygen from the air.
- Insufficient levels of dissolved oxygen can lead to hypoxia, a condition where organisms are deprived of the oxygen they need to survive. This can result in stress, reduced growth, reproductive issues, and even mortality in aquatic species.
Different species of aquatic organisms have varying tolerance levels for dissolved oxygen. For example:
- Fish and other aquatic animals often require dissolved oxygen levels between 4 to 6 milligrams per liter (mg/L) to thrive.
- Some species of fish, insects, and other aquatic organisms can tolerate lower levels of dissolved oxygen, even below 2 mg/L, while others require higher concentrations.
6. What are chemical oxygen demand and biological oxygen demand?
Chemical Oxygen Demand (COD):
- COD is a measure of the amount of oxygen required to chemically oxidize and break down organic and inorganic substances present in water.
- It provides an indication of the total amount of pollutants that can be chemically oxidized by a strong oxidizing agent. COD is expressed in milligrams per liter (mg/L) of oxygen consumed.
- COD is useful in assessing the overall pollution load in a water sample, including both biodegradable and non-biodegradable substances.
- It is commonly used for industrial wastewater monitoring, as it provides a rapid estimation of the organic content and potential pollution levels. However, COD does not differentiate between different types of pollutants or indicate the potential impact on aquatic life.
Biological Oxygen Demand (BOD):
- BOD measures the amount of dissolved oxygen consumed by microorganisms (bacteria) during the biological degradation of organic matter in water.
- It is a key indicator of the level of biodegradable organic pollutants present in water. BOD is expressed in milligrams per liter (mg/L) of oxygen consumed over a specific time period, usually 5 days (BODâ‚…).
- BOD is particularly important in assessing the impact of organic pollution on aquatic ecosystems.
- High BOD levels indicate that a water body may have a significant amount of organic pollutants, which can lead to oxygen depletion as microorganisms break down the organic matter. This oxygen depletion, known as hypoxia, can harm aquatic organisms and disrupt the ecological balance of the water body.
Comparing BOD and COD:
- BOD primarily measures the biologically degradable organic matter and provides information about the potential impact on aquatic life.
- COD measures both biologically and chemically degradable pollutants, giving an indication of the overall pollution load and oxygen demand.
- BOD is a more specific and ecologically relevant parameter, but it takes longer to determine (5 days), while COD can be measured more quickly.
For Prelims: National Green Tribunal (NGT), National Green Tribunal Act, of 2010, Dissolved oxygen (DO), Chemical Oxygen demand (COD), and Biological Oxygen Demand (BOD).
For Mains: 1. Discuss the significance of Chemical Oxygen Demand (COD) and Biological Oxygen Demand (BOD) as critical indicators for assessing water pollution and quality. (250 Words)

PURCHASING MANAGERS INDEX (PMI)
- PMI is typically calculated through surveys of purchasing managers in various industries. These managers are asked about their perception of different aspects of business activity, including new orders, production levels, employment, supplier deliveries, and inventories.
- PMI is usually reported as a number between 0 and 100.
- A PMI value above 50 generally indicates expansion in the sector, while a value below 50 suggests contraction. The farther the PMI is from 50, the stronger the perceived expansion or contraction.
- PMI is considered a leading indicator because it provides insights into economic conditions before official economic data, such as GDP growth or employment figures, are released. It can be used to anticipate changes in economic activity.
- PMIs are calculated separately for manufacturing and services sectors. A Manufacturing PMI focuses on the manufacturing sector, while a Services PMI provides insights into the services sector. These sector-specific PMIs can give a more detailed view of the economy.
Components: PMI is composed of several components, including:
- New Orders: This component measures the number of new orders received by businesses. An increase in new orders often signals growing demand and economic expansion.
- Production: This component reflects changes in production levels. An increase suggests increased economic activity.
- Employment: The employment component indicates changes in the level of employment within the sector. An increase typically means job growth.
- Supplier Deliveries: This measures the speed at which suppliers can deliver materials. Slower deliveries may indicate supply chain issues or increased demand.
- Inventories: Inventory levels can be an indicator of expected demand. A decrease in inventories might suggest an expectation of rising demand.
- The Purchasing Managers' Index (PMI) is a significant economic indicator with several important implications and uses
- PMI serves as a barometer of the economic health of a country or region. A PMI above 50 generally indicates economic expansion, while a PMI below 50 suggests contraction.
- This provides a quick and easily understandable snapshot of the direction of economic activity, making it a valuable tool for assessing the overall economic climate.
- PMI is a leading indicator, meaning it often provides insights into economic conditions ahead of other official economic data, such as GDP growth or employment figures. As such, it is used by businesses, investors, and policymakers to anticipate changes in economic activity and make informed decisions
Previous Year Questions
1.What does S & P 500 relate to? (UPSC CSE 2008) (a) Supercomputer Answer: (d) |
UNLAWFUL ACTIVITIES (PREVENTION) ACT (UAPA)
The Unlawful Activities (Prevention) Act (UAPA) is an Indian law that was enacted in 1967 to effectively prevent unlawful activities that pose a threat to the sovereignty and integrity of India.
Key highlights of the UAPA
- Objective: The primary objective of the UAPA is to provide law enforcement agencies with effective tools to combat terrorism and other activities that threaten the security of the nation.
- Definition of Unlawful Activities: The act defines unlawful activities to include actions that intend to or support the cession of a part of the territory of India or disrupt the sovereignty and integrity of the country.
- Powers of Designation: The government has the authority to designate an organization as a terrorist organization if it believes that such an organization is involved in terrorism. This designation has significant legal consequences, including the freezing of assets.
- Powers of Arrest and Detention: The UAPA provides law enforcement agencies with powers of arrest and detention to prevent individuals from engaging in unlawful activities. The act allows for preventive detention to curb potential threats before they materialise.
- Banning of Terrorist Organizations: The government can proscribe organizations as terrorist organizations, making their activities illegal. This includes banning these organisations, freezing their assets, and taking other measures to curb their operations.
- Admissibility of Confessions: The UAPA allows for confessions made to police officers to be admissible in court, subject to certain safeguards. This provision has been a point of contention, with concerns about potential misuse and coercion.
- Designation of Individuals as Terrorists: In addition to organizations, the UAPA allows the government to designate individuals as terrorists. This designation carries legal consequences, including restrictions on travel and freezing of assets.
- Amendments and Stringency: Over the years, the UAPA has undergone several amendments to strengthen its provisions and make it more effective in dealing with emerging threats. However, these amendments have also been criticized for potential violations of civil liberties.
- International Cooperation: The UAPA allows for cooperation with foreign countries in matters related to the prevention of unlawful activities. This includes extradition of individuals involved in such activities.
3. Unlawful Activities (Prevention) Act (UAPA) and Human Rights
The Unlawful Activities (Prevention) Act (UAPA) and human rights lie in the impact the act can have on various fundamental rights guaranteed by the Constitution of India and international human rights standards.
The key points connecting the UAPA and human rights:
- The UAPA allows for preventive detention, which means individuals can be detained without formal charges based on suspicions of involvement in unlawful activities. This raises concerns about the right to liberty, as individuals may be deprived of their freedom without the presumption of innocence until proven guilty.
- The admissibility of confessions made to police officers under the UAPA raises issues related to the right against self-incrimination. There is a risk that such confessions might be obtained under duress or coercion, compromising the fairness of legal proceedings.
- Designating individuals as terrorists and proscribing organizations without due process may impinge on the right to a fair trial. This includes the right to be informed of charges, the right to legal representation, and the right to present a defense.
- The UAPA provides authorities with the power to proscribe organizations as terrorist organizations, limiting their activities. Critics argue that this may infringe upon the right to freedom of association, particularly when such designations are made without sufficient evidence or proper legal procedures.
- The potential for misuse of the UAPA to target individuals or organizations critical of the government raises concerns about freedom of expression. If the act is used to suppress dissent or stifle legitimate political or social activities, it can undermine this fundamental right.
- The UAPA grants authorities the power to intercept communications and conduct surveillance on individuals suspected of engaging in unlawful activities. This raises concerns about the right to privacy, as individuals may be subjected to intrusive surveillance without adequate safeguards.
- Human rights standards require that any restrictions on rights, such as those imposed by the UAPA, must be proportionate and necessary for achieving a legitimate aim. Critics argue that the broad scope of the UAPA may lead to disproportionate measures that unduly restrict individual rights.
- The UAPA's compatibility with international human rights standards, including the International Covenant on Civil and Political Rights (ICCPR), is a critical point of consideration. Ensuring that the act aligns with these standards is essential to upholding human rights principles.
4. Unlawful Activities (Prevention) Act (UAPA) and Article 22 of the Constitution
The Unlawful Activities (Prevention) Act (UAPA) and Article 22 of the Indian Constitution lie in how the UAPA's provisions for arrest and detention intersect with the constitutional safeguards provided under Article 22.
- Article 22 provides certain protections to individuals who are arrested or detained. It outlines the rights of arrested individuals, emphasizing safeguards to prevent arbitrary or unlawful detention.
- Article 22(1) states that every person who is arrested and detained shall be informed, as soon as may be, of the grounds for such arrest. This provision ensures that individuals are aware of the reasons behind their arrest, preventing arbitrary or secret detentions.
- Article 22(1) also guarantees the right of an arrested person to consult and be defended by a legal practitioner of their choice. This ensures that individuals have access to legal assistance during the legal process, contributing to a fair and just legal system.
- The UAPA includes provisions for preventive detention, allowing authorities to detain individuals to prevent them from committing certain offences. However, Article 22(4) allows preventive detention only under specific circumstances, and certain safeguards must be followed, such as providing the detenu with the grounds for detention and an opportunity to make a representation against the detention.
- Article 22(4) further mandates that a person detained under a law providing for preventive detention must be afforded the earliest opportunity to make a representation against the detention. Additionally, the case of every person detained is required to be placed before an advisory board within three months.
- The UAPA allows for confessions made to police officers to be admissible in court, subject to certain safeguards. However, this provision has been a point of concern concerning Article 22, as confessions obtained under duress or coercion may violate the right against self-incrimination.
- Article 22(2) ensures the right to be brought before the nearest magistrate within 24 hours of arrest, excluding the time necessary for the journey. This provision aims to prevent prolonged detention without judicial oversight and contributes to the right to a speedy trial.

3D PRINTING
1. Context
2. What is 3D Printing?
- 3D printing, also known as additive manufacturing, is an innovative technology that has redefined traditional manufacturing processes.
- It involves the creation of three-dimensional objects by adding material layer by layer, guided by a computer-generated design.
- This method contrasts with subtractive manufacturing, where the material is removed from a solid block to achieve the desired shape.
3. Process Overview:
- Design: The process begins with a digital 3D model created using computer-aided design (CAD) software. This virtual blueprint guides the printer on how to construct the physical object.
- Layering: The 3D printer interprets the digital model and begins the additive process. It deposits material, often in the form of plastic, metal, or composite, layer by layer to form the final object.
- Building Up: As each layer is added, the object gradually takes shape. The printer's precision ensures the accurate reproduction of intricate details, resulting in a three-dimensional physical replica of the digital model.
4. Key Advantages:
- Complex Geometry: 3D printing enables the creation of highly complex and intricate geometries that might be challenging or impossible to achieve through traditional manufacturing methods.
- Customization: It allows for personalized and customizable products, catering to the specific needs and preferences of users.
- Rapid Prototyping: The technology is widely used for rapid prototyping, allowing designers and engineers to quickly iterate and test ideas before committing to full-scale production.
- Reduced Material Waste: Unlike subtractive manufacturing, where excess material is often discarded, 3D printing adds material only where needed, minimizing waste.
- On-Demand Production: 3D printing facilitates on-demand manufacturing, reducing the need for mass production and warehousing.
5. Applications and Challenges
- Aerospace: Used to create lightweight, high-performance components for aircraft and spacecraft.
- Healthcare: Utilized for producing patient-specific medical implants, prosthetics, and even human tissue.
- Automotive: Enables rapid prototyping of vehicle components and customization.
- Fashion: Designers employ 3D printing to create unique and avant-garde clothing and accessories.
- Architecture: Used in creating detailed architectural models and prototypes.
Challenges
- Limited material options compared to traditional manufacturing.
- Slower production speed for larger objects.
- Post-processing may be required to achieve desired surface finishes.
6. Conclusion
3D printing has revolutionized the way objects are designed, manufactured, and customized. Its ability to create intricate and unique structures with precision has found applications across diverse industries, promising continued innovation and reshaping the manufacturing landscape.

SPECIAL MARRIAGES ACT
1. Context
2. About Special Marriages Act
- The Special Marriage Act of 1954 (SMA) was passed by the Parliament on October 9, 1954.
- It governs a civil marriage where the state sanctions the marriage rather than the religion.
- Issues of personal law such as marriage, divorce and adoption are governed by religious laws that are codified.
These laws, such as the Muslim Marriage Act, of 1954 and the Hindu Marriage Act, of 1955, require either spouse to convert to the religion of the other before marriage. - However, the SMA enables marriage between inter-faith or inter-caste couples without them giving up their religious identity or resorting to conversion.
- The Indian system, where both civil and religious marriages are recognised, is similar to the laws in the UK's marriage Act of 1949.
- An earlier version of the SMA was enacted in 1872 and was later re-enacted in 1954 with provisions for divorce etc.
3. Marriage under the Special Marriage Act
- The applicability of the Act extends to people of all faiths, including Hindus, Muslims, Sikha, Christians, Sikhs, Jains and Buddhists across India.
- Some customary restrictions such as parties not being within degrees of a prohibited relationship still apply to couples under SMA.
- In 1952, when the Bill was proposed, the requirement of monogamy was considered radical.
Section 4 of the SMA requires that at the time of marriage, "neither party has a spouse living" or is "incapable of giving a valid consent to it in consequence of unsoundness of mind".
Even if both parties are capable of giving valid consent, it requires that they do not suffer from "recurrent attacks of insanity" or any mental disorder that renders them "unfit for marriage and the procreation of children".
|
- The minimum age to get married under the SMA is 21 years for males and 18 years for females.
- However, once married as per the secular law, under Section 19 of the Act, any member of an undivided family who professes the Hindu, Buddhist, Sikh or Jain religion shall be deemed to affect their severance from the family. This would affect the rights, including the right to inheritance, of the persons choosing to marry under the SMA.
4. The procedure for a civil marriage
- As per Section 5 of the Act, the parties to the marriage are required to give a notice, in writing to a "Marriage Officer" of the district in which at least one of the parties has resided for at least 30 days immediately preceding the notice.
- Before the marriage is solemnized, the parties and three witnesses are required to sign a declaration form before the Marriage Officer.
- Once the declaration is accepted, the parties will be given a "Certificate of marriage" which is essentially proof of the marriage or conclusive evidence of the fact that a marriage under this Act has been solemnized and all formalities respecting the signatures of witnesses have been complied with.
5. Notice period under the SMA
- As per Section 6, a true copy of the notice given by the parties will be kept under the "Marriage Notice Book" which will be open for inspection at all reasonable times, without a fee.
- Upon receiving the notice, the marriage officer shall publish it in "some conspicuous place in his office" to invite any objections to the marriage within 30 days.
Section 7 deals with "Objection to marriage and allows any person "before the expiration of thirty days from the date of the notice's publication" to object to the marriage on the ground that it would contravene one or more of the conditions specified in Section 4 of the Act. |
- If an objection has been made, the Marriage Officer cannot solemnize the marriage until he had inquired into the matter of the objection and is satisfied that will not prevent the marriage from taking place unless the person making such an objection withdraws it.
6. Criticism
- These provisions are often criticised as they are commonly invoked to harass consenting couples.
- In 2009, the Delhi High Court, underlining the right to privacy, struck down the practice of posting the notice of intended marriage under the SMA to the residential addresses of both parties through the police station of the concerned jurisdiction to verify their addresses.
- The unwarranted disclosure of matrimonial plans by two adults entitled to solemnize it may, in certain situations, jeopardize the marriage itself.
- In certain instances, it may even endanger the life or limb of one the other party due to parental interference.
- More recently, this requirement for a notice period has also been challenged.
- In January 2021, the Allahabad High Court ruled that couples seeking to solemnize their marriage under the Special Marriage Act, 1954 can choose not to publish the mandatory 30-day notice of their intention to marry.

LAHORE DECLARATION
The Kargil conflict, also known as the Kargil War, was an armed conflict between India and Pakistan between May and July 1999 in the Kargil district of Jammu and Kashmir, along the Line of Control (LoC).
Causes and Planning
- The primary motive for Pakistan's incursion was to disrupt the lifeline of the Indian military in Siachen and to internationalize the Kashmir issue by bringing it back into focus. By occupying high-altitude positions, Pakistan aimed to sever the link between Ladakh and Kashmir and force India to negotiate.
- Pakistani soldiers and militants, disguised as insurgents, infiltrated across the LoC into the Indian side in the Kargil sector. They occupied strategic peaks and ridges, from where they could dominate the vital National Highway 1A, which connects Srinagar to Leh.
- The infiltration was discovered in early May 1999 when local shepherds reported unusual activity. The Indian Army initially thought the infiltrators were militants, but later realized that the intruders were well-equipped regular Pakistani soldiers and well-trained militants.
- India launched Operation Vijay to evict the intruders. The operation involved mobilizing a large number of troops and using artillery, air power, and infantry assaults to dislodge the Pakistani forces from the high-altitude positions they had occupied.
- The Indian Air Force (IAF) conducted air strikes against the infiltrators, marking the first time since the 1971 war that air power was used in the region. The IAF faced significant challenges due to the high-altitude terrain and the need to avoid crossing the LoC to prevent escalation.
- Fierce ground battles were fought at high altitudes, often over 16,000 feet, in extremely harsh conditions. Key battles took place at points such as Tololing, Tiger Hill, and Batalik, where Indian forces faced well-entrenched Pakistani positions.
