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.

FOREIGN CONTRIBUTION REGULATION ACT (FCRA)
1. Context
2. Foreign Contribution Regulation Act
- The law sought to regulate foreign donations to individuals and associations so that they functioned "in a manner consistent with the values of a sovereign democratic republic".
- Foreign funding in India is regulated under the FCRA act. Individuals are permitted to accept foreign contributions without the permission of MHA. However, the monetary limit for acceptance of such foreign contributions shall be less than Rs. 25,000.
- It is implemented by the Ministry of Home Affairs. The FCRA was enacted during the Emergency in 1976 amid apprehensions that foreign powers were interfering in India's affairs by pumping money into the country through independent organizations. These concerns were, in fact, even older- they had been expressed in Parliament as early as 1969.
3. Provisions of the Act
- The FCRA requires every person or NGO wishing to receive foreign donations to be registered under the act, to open a bank account for the receipt of foreign funds in the statute Bank of India, Delhi, and to utilize those funds only for which they have been received, and as stipulated in the act.
- They are also required to file annual returns, and they must not transfer the funds to another NGO.
- The Act prohibits the receipt of foreign funds by candidates for elections, journalists or newspapers and media broadcast companies, judges and government servants, members of the legislature and political parties or their office-bearers, and organizations of a political nature.
4. Key Highlights of the 2020 Amendment
- It bars public servants from receiving foreign contributions. It prohibits the transfer of foreign contributions to any other person.
- Aadhar number is mandatory for all office bearers, directors, or key functionaries of a person receiving foreign contributions, as an identification document.
- The foreign contribution must be received only in an account designated by the bank as an FCRA account in such branches of the State Bank of India, New Delhi.
- No funds other than foreign contributions should be received or deposited in this account.
- It allowed the government to restrict the usage of unutilized foreign contributions. This may be done if, based on an inquiry the government believes that such a person has contravened provisions of the FCRA.
- While NGOs earlier could use up to 50 percent of funds for administrative use, the new amendment restricted this use to 20 percent.
5. Registration under FCRA
- NGOs that want to receive foreign funds must apply online in a prescribed format with the required documentation. FCRA registrations are granted to individuals or associations that have definite cultural, economic, educational, religious, and social programs.
- Following the application, the MHA makes inquiries through the Intelligence Bureau into the antecedents of the applicant and accordingly processes the application. The MHA is required to approve or reject the application within 90 days-failing which is expected to inform the NGO of the reasons for the same.
- Once granted, FCRA registration is valid for five years. NGOs are expected to apply for renewal within six months of the date of expiry of registration. In case of failure to apply for renewal, the registration is deemed to have expired.
6. Cancellation of Approval
The government reserves the right to cancel the FCRA registration of any NGO if it finds it to violate the Act. Registration can be cancelled for a range of reasons including, if "in the opinion of the Central Government, the public interest must cancel the certificate". Once the registration of an NGO is canceled, it is not eligible for re-registration for three years. All orders of the government can be challenged in the High court.

RABI CROPS
1. Context
2. Rabi Crops
- Rabi crops are also known as Winter crops. They grow during the winter season which starts in October and March. The Arabic term ‘Rabi’ denotes spring. hence, the harvesting time for Rabi crops begins during the Spring season. Unlike Kharif crops, Rabi crops require less water to grow.
- Therefore, they can easily grow with the help of routine water irrigation to flourish. Types of Rabi crops include Wheat, Barley, Pulses, Gram, and more.
- Moreover, farmers also sow seeds of Mustard, Cumin, Sunflower, Rapeseed, and more during this season.
- Some of examples of rabi crops grown in India are wheat, mustard, barley, green peas, sunflower, coriander, cumin, etc.
3. How the different Seasons effects the Rabi crop?
- The majority of field crops rely solely on the weather to provide life-sustaining water and energy. The comfort and food supplies of livestock are also dependent on the weather. Adverse weather conditions can occasionally result in productivity losses, especially if they occur during vital stages of growth.
- Due to the general warmer spring environment, farmers can sow the first crop (winter barley) earlier than usual, allowing them to produce the second crop (rapeseed) for the remainder of the growing season, improving soil fertility and income.
- The availability of water and fertile soil (soil deposition is driven by water transportation) is another limiting element of cropland growth in the area, therefore agricultural expansion and intensification are currently confined to a specific distance from main river systems.
4. Changing monsoon
- 2022-23 has been quite different. Rainfall was 37.4% below the all-India average in November, with the corresponding deficits at 14.5% for December and 57.5% during January 1-22.
- The shortfalls have been greater in northern, central, and western India, where much of the rabi winter-spring crops — especially wheat, mustard, chana (chickpea), and masur (red lentil), as also maize, potato and onion — are grown.
- The India Meteorological Department has forecast “scattered to fairly widespread rainfall accompanied by thunderstorm activity” over Punjab, Haryana, Delhiand Uttar Pradesh during January 24-26, besides “light isolated” rain over north Rajasthan and Madhya Pradesh.
- A fresh western disturbance is expected to bring more rain over northwest India from January 27.
5. How This Changing Monsoon will impact the Rabi Crops?
- Farmers have sown wheat on 341.13 lakh hectares (lh) this time, as against 339.87 lh in 2021-22, and a normal area of 304.47 lh.
- That should ordinarily translate into bumper production -required particularly in the context of annual retail cereal inflation hitting 13.79% in December and wheat stocks in government warehouses on January 1 at a six-year-low.
- But given that harvesting is more than two months away and knowing the havoc untimely heavy rain and hailstorms (as in March 2015) or early onset of summer (March 2022) can wreak making any output predictions based on crop acreages is fraught with risk.
6. Major Rabi crop- Wheat
- A large amount of agricultural income for India comes through the production of wheat. India is the second-largest producer of this wheat crop in the world.
- Wheat requires low temperatures to grow, thus winter is the suitable season for farming this Rabi crop. The ideal temperature range should be around 140 to 180 C with a rainfall of 50 cm to 90cms. The crop is harvested in spring when the temperature is slightly warm.
- In India, Uttar Pradesh is the largest wheat-producing state which is closely followed by Punjab and Haryana.
- Wheat crops are typically planted from September to December in various Indian states, depending on the environment, and harvested from February to May, again depending on the climate and the time of seeding. Wheat has become a successful crop thanks to technological improvements in soil preparation and seed placement at planting time, crop rotation and fertilizer use to increase plant growth, and advances in harvesting processes.

GREAT INDIAN BUSTARD
1. Context
2. Endangering GIBs
- Hearing petitions highlighting deaths of the GIBs due to power transmission lines, a special bench of the apex court was formed.
- This apex court directed the Chief Secretaries of Gujarat & Rajasthan to undertake a comprehensive exercise to find out the total length of transmission lines in question and the number of bird diverters required.
- This is not the first time that the Supreme Court had intervened in the conservation of the GIB.
- In 2021, the Supreme Court directed the authorities to convert the overhead cables into underground powerlines, within one year & the time diverters were to be hung from existing power lines.
3. Power Lines-Threat
- Several threats have led to the decline of the GIB population, but powerlines seem to be the most significant.
- In different parts of the world, the bustard populations have shown high mortality because of power lines like Denham's bustard in South Africa, and Great Indian Bustard in Spain.
- GIBs are large birds standing about one metre tall & weighing about 15-18 kilos.
- The GIBs are not great fliers & have sideways vision to maximise predator detection but the species' frontal vision is narrow.
- These birds cannot detect power lines from far & since they are heavy fliers, they fail to manoeuvre across power lines within close distances.
- The combination of these traits makes them vulnerable to collision with power lines.
- In most cases, death is due to collision rather than electrocution.
- A study by the Wildlife Institute of India (WII) in 2020 recorded 6 cases of GIB mortality due to power-line collisions in Thar from 2017-20.
4. Preventive Steps
- The GIBs enjoy the highest protection both in India & globally, as per Schedule I of the Indian Wildlife (Protection) Act, 1972, in Appendix I of CITES, as Critically Endangered on the IUCN Red List.
- The population of GIBs was 1,260 in 1969 but has declined by 75% in the last 30 years.
- GIB population was distributed among 11 states in western India, but now the population is restricted to Rajasthan & Gujarat.
- Small populations are found in Maharashtra, Karnataka & Andhra Pradesh.
The overall population of the GIB totals 150 across the country, 128 in Rajasthan.
A total of 16 GIB chicks, artificially hatched from eggs collected from the wild, are being reared in the satellite conservation breeding facility in Rajasthan.
The objective of Habitat Improvement & Conservation Breeding of Great Indian Bustard, an integrated approach is to build the captive population of the GIBs & to release the chicks in the wild.
|
- The initiative is likely to take 20-25 years.
- Scientists from WII, have called for removing all overhead powerlines passing through the GIB priority/critical areas in Rajasthan.
5. Other Threats
- GIBs are slow breeders & they build their nests on the ground.
- The species were subjected to hunting & egg collection in the past.
- There was a decline in prevailing habitat loss as dry grasslands were diverted for other use.
- Experts warn of pesticide contamination & increase in populations of free-ranging dogs & pigs along with native predators, putting pressure on nests & chicks.
- Most of the population of the species is confined to the Jaisalmer Desert National Park (DNP), Wildlife enthusiasts believe that more areas outside the protected area must be made suitable for the species.
- A conservation effort like "Project Tiger" may not work for a large bird of an arid region that can always fly out of the protected area.

GOOD FRIDAY
Good Friday is observed by Christians as a day of solemn remembrance and reflection on the crucifixion of Jesus Christ. It is part of the Holy Week, which commemorates the events leading up to Jesus' death and resurrection, as recounted in the New Testament of the Bible.
The observance of Good Friday serves several purposes:
- Good Friday is a time for Christians to remember and reflect on the sacrifice of Jesus Christ, who, according to Christian belief, willingly suffered and died on the cross to atone for the sins of humanity. It is considered the culmination of Jesus' earthly ministry and the fulfillment of God's plan for salvation
- Good Friday provides an opportunity for believers to engage in prayer, meditation, and spiritual reflection. It is a day for introspection, repentance, and gratitude for the love and mercy demonstrated through Jesus' sacrifice
- Good Friday has been observed by Christians for centuries as a significant day in the liturgical calendar. Churches around the world hold special services and ceremonies, including the Stations of the Cross, readings from the Scriptures, hymns, and prayers, to commemorate the passion and death of Jesus Christ
- Good Friday is a unifying experience for Christians of various denominations, as they come together to remember and commemorate the central event of their faith. It serves as a reminder of the common bond shared by believers in the death and resurrection of Jesus Christ
- Good Friday is also a time of preparation for Easter Sunday, which celebrates the resurrection of Jesus Christ. By observing Good Friday with reverence and solemnity, Christians prepare themselves spiritually to fully experience the joy and hope of Easter.
3. Why is it called ‘Good’ Friday?
The term "Good Friday" may seem paradoxical given that it commemorates the crucifixion and death of Jesus Christ, which is a solemn and sorrowful event in Christian tradition.
However, there are several theories regarding the origin of the term:
-
"Good" as a Corruption of "God": One theory suggests that "Good Friday" originated from an older English term, "God's Friday," which evolved over time into "Good Friday." In this context, "good" was used to denote something holy, sacred, or significant, rather than indicating a positive or joyful event.
-
"Good" as Meaning "Holy" or "Pious": Another interpretation is that "Good Friday" refers to the goodness or holiness of Jesus' sacrifice on the cross. From a Christian perspective, Jesus' death is seen as a redemptive act that brought salvation to humanity, making the day "good" in the sense of being spiritually significant and beneficial for believers.
-
"Good" as a Day of Mourning Turned into Celebration: Some historians suggest that "Good Friday" may have originally been called "God's Friday" by early Christians, but over time, the term evolved to reflect the positive outcome of Jesus' sacrifice, leading to the celebration of Easter Sunday and the resurrection. Thus, "Good Friday" came to be understood as the necessary precursor to the joyous event of Easter.
-
Contrast with Other Days: In some languages, including German ("Karfreitag") and Dutch ("Goede Vrijdag"), the term for Good Friday translates to "Sorrowful" or "Suffering Friday," highlighting the solemn nature of the day compared to the celebration of Easter. The contrast between the suffering of Good Friday and the joy of Easter Sunday emphasizes the significance of Jesus' sacrifice and resurrection in Christian theology
Good Friday, along with Easter Sunday and other movable feast days in the Christian calendar, does not have a fixed date each year. Instead, its date varies from year to year. The reason for this is rooted in the way Easter is calculated, which in turn determines the date of Good Friday.
Here's why the dates for Good Friday differ every year:
-
Based on the Lunar Calendar: The date of Easter, and consequently Good Friday, is determined by the lunar calendar. Specifically, it is based on the timing of the full moon following the vernal equinox (the first day of spring in the Northern Hemisphere).
-
Council of Nicaea: In 325 AD, the Council of Nicaea established a standardized method for calculating the date of Easter. It was determined that Easter would fall on the Sunday following the first full moon after the vernal equinox.
-
Eastern vs. Western Churches: While both Eastern and Western Christian churches follow the same method for calculating Easter, they use different calendars. The Eastern Orthodox Church uses the Julian calendar for determining the date of Easter, while most Western churches, including Roman Catholic and Protestant denominations, use the Gregorian calendar.
-
Occurrence of the Equinox and Full Moon: Because the vernal equinox and the phases of the moon do not align precisely with the Gregorian calendar, the date of Easter fluctuates from year to year. Easter can occur as early as March 22nd or as late as April 25th.
-
Computus: The process of calculating the date of Easter is known as "computus." It involves complex astronomical and calendrical calculations to determine the timing of the equinox and the full moon. Church authorities perform these calculations each year to establish the date of Easter and, consequently, Good Friday
- Many Christians attend special church services on Good Friday. These services often include readings from the biblical accounts of Jesus' passion and death, such as the Gospel narratives of the Crucifixion. Hymns, prayers, and reflections are also part of the service, focusing on the significance of Jesus' sacrifice and the meaning of the cross
- In some Christian traditions, a ceremony known as the "Veneration of the Cross" is held on Good Friday. During this ceremony, a cross or crucifix is displayed prominently in the church, and worshippers may come forward to kiss or touch the cross as an act of reverence and devotion
- The Stations of the Cross, also known as the Way of the Cross or Via Dolorosa, are a series of images or sculptures depicting the events of Jesus' crucifixion and death. Many churches have stations set up for worshippers to pray and meditate on each stage of Jesus' journey to the cross
- Good Friday is often observed as a day of fasting and abstinence in many Christian traditions. Some believers abstain from meat or certain foods, while others may refrain from eating altogether for a portion of the day, particularly during the hours traditionally associated with Jesus' crucifixion
- Good Friday is a day of quiet reflection and solemnity, marked by a subdued atmosphere in churches and among believers. Many Christians observe periods of silence or engage in personal prayer and meditation as they contemplate the significance of Jesus' sacrifice
- Some Christians use Good Friday as an opportunity to perform acts of compassion and service in their communities. This may include volunteering at homeless shelters, visiting the sick or elderly, or engaging in other forms of charitable work as a way of embodying the spirit of Christ's selfless love

4. The Low Earth Orbit (LEO)
The Low Earth Orbit (LEO) refers to a region of space situated relatively close to the Earth's surface, characterized by altitudes typically ranging from about 160 kilometres (100 miles) to 2,000 kilometres (1,200 miles) above sea level. LEO is one of the most commonly utilized orbital regimes for various space missions and satellite deployments due to its proximity to Earth and favourable orbital characteristics.
Key features and characteristics of Low Earth Orbit (LEO) include
- LEO orbits are situated at relatively low altitudes compared to other orbital regimes, such as Medium Earth Orbit (MEO) or Geostationary Orbit (GEO). Altitudes in LEO typically range from approximately 160 kilometres to 2,000 kilometres above the Earth's surface.
- Many Earth observation satellites, communication satellites, scientific research satellites, and space stations, including the International Space Station (ISS), are placed in LEO. These satellites orbit the Earth at high speeds, completing multiple orbits each day.
- Satellites in LEO have relatively short orbital periods due to their proximity to Earth. They complete orbits around the Earth in a matter of hours, typically ranging from about 90 minutes to 2 hours per orbit.
- Satellites in LEO are often visible to observers on the ground, especially during dawn or dusk when sunlight reflects off their surfaces. This makes LEO satellites popular targets for amateur astronomers and skywatchers.
- LEO offers several advantages for satellite missions, including lower launch costs compared to higher orbits, shorter communication delays (lower latency) for satellite-based services, and the ability to achieve high-resolution Earth imaging for remote sensing applications.
- Despite its advantages, LEO also presents challenges, such as increased atmospheric drag that can cause orbital decay over time, requiring periodic adjustments or re-boost manoeuvres to maintain satellite orbits. Additionally, the dense concentration of satellites in LEO poses concerns about space debris and collision avoidance.
