Why in News?

Recently, Parliament passed two bills that aim to modify the lists of Scheduled Castes (SC) and Scheduled Tribes (ST) in Andhra Pradesh and Odisha. The bills were passed by voice vote in the Lok Sabha.

Voice Vote

  • It involves the speaker putting a question to the house and then asking the house to put forward its opinion in the forms of ayes (yes) or noes. Based on a rough measure of which side was louder, the speaker decides if the motion was passed or fell through.

What are the Bills and What do they Propose?

  • Andhra Pradesh: The Constitution (Scheduled Tribes) Order (Amendment) Bill, 2024 seeks to amend the Constitution (Scheduled Tribes) Order, 1950, in relation to Andhra Pradesh.
    • The Order lists the tribes deemed to be Scheduled Tribes in states and union territories.
    • The Bill adds the following Particularly Vulnerable Tribal Groups (PVTGs) to the list of STs in Andhra Pradesh: (i) Bondo Porja, (ii) Khond Porja, and (iii) Konda Savaras.
  • Odisha: The Constitution (Scheduled Castes and Scheduled Tribes) Orders (Amendment) Bill, 2024 amends the Constitution (Scheduled Castes) Order, 1950 and the Constitution (Scheduled Tribes) Order, 1950 to modify the list of SCs and STs in Odisha.
    • PVTGs added to the Scheduled Tribes list in Odisha:
      • Pauri Bhuyan and Paudi Bhuyan (included as synonyms of Bhuyan Tribe).
      • Chuktia Bhunjia (recognized as Bhunjia tribe).
      • Bondo community (sub-tribe of Bondo Poraja).
      • Mankidia community (synonym of Mankirdia tribe).
    • Odisha's ST list expanded with two new entries: Muka Dora (also Mooka Dora, Nuka Dora and Nooka Dora) and Konda Reddy (also Konda Reddi) tribes.
    • The Bill removes Tamadia and Tamudia communities from the list of SCs in Odisha and adds them to the list of STs.

Note

  • The bills only added synonyms, phonetic variations, and sub-tribes of existing STs in Odisha and Andhra Pradesh; the count of PVTGs in India remains unchanged at 75.

What is the Importance of these Bills?

  • The amendment addresses discrepancies in the treatment of certain tribes across different regions.
    • Communities like Konda Reddy and Muka Dora were recognized as ST in Andhra Pradesh but faced discrimination in Odisha.
    • The inclusion of these groups in the ST list rectifies long-standing disparities, ensuring equitable access to government provisions and services.
  • PVTGS listed as STs gain access to reservation quotas in education, employment, and political representation.
    • ST status ensures affirmative action in educational institutions, allowing PVTG students to compete on a level playing field.

What is a Particularly Vulnerable Tribal Group?

  • About:
    • A PVTG is a sub-classification of a Scheduled Tribe or section of a Scheduled Tribe that is considered more vulnerable than a regular Scheduled Tribe. The Indian Government created the PVTG list to improve their living.
      • There are 75 PVTGs in India, the maximum 13 are in Odisha, followed by 12 in Andhra Pradesh.
    • Article 342(1): The President with respect to any State/UT (after consultation with the Governor in case of state) may specify the tribes/tribal communities/part of or groups within tribes/ tribal communities as a Scheduled Tribe in that State/UT.
      • Parliament may by law include in or exclude from the list of STs specified in a notification issued under article 342(1) any tribe or tribal community or part of or group within any tribe or tribal community, but save as aforesaid a notification issued under the said clause shall not be varied by any subsequent notification.

Why in News?  

In 2021, the Support for Marginalized Individuals for Livelihood and Enterprise (SMILE) scheme, aimed at advancing the vision of Viksit Bharat  was initiated. This included the launch of the Central Sector Scheme for Comprehensive Rehabilitation for the Welfare of Transgender Persons.  

Who is a Transgender?  

  • According to the Transgenders Persons Act, 2019, transgender means a person whose gender does not match with the gender assigned to that person at birth.  
  • It includes trans-person with intersex variations, gender-queer and person having such socio-cultural identities as kinnar, hijra, aaravani and jogta.  
  • India’s 2011 Census was the first census in its history to incorporate the number of ‘trans’ population of the country. The report estimated that 4.8 million Indians identified as transgender.  

What is a SMILE Scheme?   

  • About:  
    • It is a new Scheme after the merger of existing Schemes for Beggars and Transgenders.  
      • The two sub-schemes of SMILE - ‘Central Sector Scheme for Comprehensive Rehabilitation for Welfare of Transgender Persons’ and ‘Central Sector Scheme for Comprehensive Rehabilitation of engaged in the act of Begging’ – provide comprehensive welfare and rehabilitation measures to the Transgender community and the people engaged in the act of begging.  
        • Scheme provides for the use of the existing shelter homes available with the State/UT Governments and Urban local bodies for rehabilitation of the transgender persons.  
        • In case of non-availability of existing shelter homes, new dedicated shelter homes are to be set up by the implementing agencies.  
  • Focus:  
    • The focus of the scheme is extensively on rehabilitation, provision of medical facilities, counselling, basic documentation, education, skill development, economic linkages and so on.  
    • It is estimated that an approximate 60,000 poorest persons would be benefited under this scheme for leading a life of dignity.  
      • It provides Scholarships for Transgender Students studying in Class 9th and above till post-graduation to enable them to complete their education.  
      • It has provisions for Skill Development and Livelihood under the PM-DAKSH scheme.  
      • Through Composite Medical Health it provides a comprehensive package in convergence with Pradhan Mantri Jan Aarogya Yojana (PM-JAY) supporting Gender-Reaffirmation surgeries through selected hospitals.  
      • The Housing facility in the form of ‘Garima Greh’ ensures food, clothing, recreational facilities, skill development opportunities, recreational activities and medical support etc. to the Transgender community and the people engaged in the act of begging.  
  • Implementation:  
    • It will be implemented with the support of State/UT Governments/Local Urban Bodies, Voluntary Organizations, Community Based Organizations (CBOs) , institutions and others.  
    • The Provision of Transgender Protection Cell in each state will monitor cases of offences and to ensure timely registration, investigation and prosecution of offences.  
    • The National Portal & Helpline will provide necessary information and solutions to the Transgender community and the people engaged in the act of begging when needed.  
  • Scheme for Comprehensive Rehabilitation of Trangenders:  
    • The scheme has been implemented in the selected cities on pilot basis having large concentrations of the Beggar and Transgender community.  
    • During the year 2019-20, this Ministry had released an amount of Rs. 1 Crore to National Institute of Social Defence (NISD) and Rs. 70 Lakh to National Backward Classes Finance & Development Corporation (NBCFDC) for skill development programmes for beggars.  

What are the Problems Faced by Transgenders?  

  • Societal Stigma:  
    • Social Exclusion: Transgender individuals often face isolation and marginalization, leading to mental health issues, substance abuse, and a reduced quality of life.  
    • Stereotyping and Misrepresentation: Society tends to stereotype transgender people, limiting their opportunities for employment, education, and healthcare.  
    • Family Rejection: Many transgender individuals are disowned by their families, leaving them without familial support and economic stability.  
  • Discrimination:  
    • Violence and Hate Crimes: Hate crimes, physical and verbal abuse, and sexual assault are significant threats to the safety and well-being of transgender individuals.  
    • Educational Barriers: Discrimination in educational institutions hampers access to quality education and future career opportunities.  
    • Employment Discrimination: Transgender individuals frequently experience job discrimination, which leads to unemployment or underemployment, perpetuating their economic vulnerability.  
    • Healthcare Disparities: Discrimination by healthcare providers often deters transgender individuals from seeking necessary medical care, including gender-affirming procedures.  
  • Absence of Legal Recognition:  
    • Legal Ambiguity: While India has made progress with the Transgender Persons (Protection of Rights) Act, 2019, there are still legal ambiguities and gaps that need to be addressed.  
      • Transgender persons are not defined properly and the Act does not have any provision for self-determination of gender.  
    • Lack of Comprehensive Policies: The absence of comprehensive policies on gender identity, non-binary genders, and a clear legal framework for transgender rights remains a challenge.  
    • Implementation Gaps: The implementation of existing laws is often ineffective due to a lack of awareness, prejudice, and reluctance on the part of authorities.  

What are the Different Initiatives for Transgender Persons?  

What Can be Done More to Uplift the Transgender Persons?  

  • Transgender-Inclusive Policies: Legal and the law enforcement systems need to be empowered and sensitized on the issues of Transgender community.  
    • Inclusive approach for Transgender must be planned and adopted by the Government and society.  
    • Their grievance of being not included in policies formulation or decision making needs to be allayed and chances for their public participation should increase.  
  • Addressing Social Concerns: Provision of free legal aid, supportive education, and social entitlement must be ensured for the Transgender community at ground level as suggested by NALSA Judgement.  
    • Separate policies related to health care must be framed and communicated in all private and public hospitals and clinics.  
    • There is a need to increase awareness and inculcate sense of respect and acceptance for transgender community.  
  • Financial Security: Liberal credit facilities and financial assistance must be ensured to start up their career as an entrepreneur or businessman along the lines of SHG-Bank Linkage Programs.   
  • Transgender in Prisons: Awareness and documentation are two important tools to address the reforms in reference to sexual minorities, especially trans prisoners.  
    • As the Commonwealth Human Rights Initiative (CHRI) advocates, there is a need for a gender-fluid approach for the treatment of transgender prisoners.  
    • The CHRI’s recommendations should be considered by the Union government to bring a ‘model policy’ on the special needs of trans prisoners, through a consultative process with the members of the trans community, to honour the mandate of the NALSA judgement.

Geography

Atmospheric River

For Prelims: Atmospheric River, Pineapple Express, National Oceanic and Atmospheric Administration (NOAA).

For Mains: Atmospheric River, Geographical features and their location, Impacts of Climate Change.

Source: TOI

Why in News?

California, US is currently grappling with an extraordinary weather phenomenon known as an Atmospheric River also called Pineapple Express Storm, which has the potential to unleash up to 8 trillion gallons of rain over the state.

What is an Atmospheric River?

  • About:
    • The atmospheric river is a long, narrow band of moisture-filled air that transports significant amounts of water vapor from the tropics to higher latitudes.
      • The Atmospheric River is often associated with mT (Maritime Tropical) air mass.
    • When these rivers make landfall, they release this moisture as intense precipitation, which can manifest as either rain or snow depending on the altitude and temperature.
    • So, when they make landfall and release all that water, they can cause extreme flooding.
  • Pineapple Express:
    • The "Pineapple Express" is a well-known example of atmospheric river storms that bring heavy rainfall to the US West Coast, particularly California.
    • This name originates from the fact that these storms draw moisture from the tropical waters near the Hawaiian Islands, resembling a "express" train of moisture originating from the vicinity of Hawaii, which is often associated with pineapples.
      • This atmospheric river is driven by a strong southern branch of the polar jet stream and transports humid, warm mT air from as far away as the Hawaiian Islands .

Satellite image of clouds over the Pacific Ocean illustrating the “Pineapple Express,” a phenomenon in which a strong jet stream carries mT air from as far away as Hawaii to the West Coast.

  • Categories:
    • Category 1 (Weak): A Category 1 atmospheric river would be a milder and briefer weather event with primarily beneficial effects, like 24 hours of modest rainfall.
    • Category 2 (Moderate): A Category 2 atmospheric river is a moderate storm with mostly beneficial effects, but also somewhat hazardous.
    • Category 3 (Strong): A Category 3 atmospheric river is more powerful and longer lasting, with a balance of beneficial and hazardous impacts. For example, a storm in this category could bring 5-10 inches of rain over 36 hours, enough to help replenish reservoirs but also pushing some rivers close to flood stage.
    • Category 4 (Extreme): A Category 4 atmospheric river is mostly hazardous, though also with some beneficial aspects. A storm of this rating could dump enough heavy rain over several days to bring many rivers to flood stage.
    • Category 5 (Exceptional): A Category 5 atmospheric river is primarily hazardous.
      • An atmospheric river that lasted over 100 hours over the Central California coast during the 1996-97 New Year's holiday period. The heavy rain and runoff caused over USD 100 billion in damage.

  • Significance:
    • They play a crucial role in replenishing water supplies, particularly in regions like the western United States. The heavy precipitation they bring can contribute significantly to reservoir levels, helping to alleviate drought conditions and ensuring water availability for agricultural, industrial, and domestic use.
    • Given their importance for water supply, understanding atmospheric rivers is essential for effective water resource management and planning. This includes strategies for water storage, flood control, and allocation of water resources to meet various demands.
    • Atmospheric rivers contribute to maintaining a balance in the hydrological cycle by transporting large amounts of water vapor from the tropics to higher latitudes. This helps to redistribute moisture across different regions, supporting ecosystems and agricultural productivity.

Note

An atmospheric river should not be confused with a traditional river found on the Earth's surface. Unlike a visible water body, an atmospheric river is an invisible, elongated corridor in the sky that carries large amounts of water vapor, influencing weather patterns and precipitation.

How Common are Atmospheric Rivers, and Where do They Occur?

  • They're not limited to the US West Coast; they can occur worldwide. These rivers of moisture can stretch thousands of miles and affect regions like the UK, Ireland, Norway, and China.
    • Atmospheric rivers often make the rainy season in China, known as Mei-Yu season, even worse.
  • While they only account for 17% of storms on the US West Coast, atmospheric rivers contribute significantly to California's precipitation, snowpack, and major floods. They're predictable and can be forecasted up to a week in advance.

What is Air Mass?

  • About:
    • An air mass is a large body of air with relatively uniform temperature, humidity, and pressure characteristics. These masses of air form over source regions, where they take on the characteristics of the surface below due to low wind speeds.
    • When air masses move, they can influence weather patterns in the regions they move into, potentially leading to the formation of storms when they interact with other air masses.
  • Types of Air Masses:
    • Continental Tropical (cT): These air masses originate over hot and dry continental regions. They are characterized by high temperatures and low humidity.
    • Continental Polar (cP): Originating over cold and dry continental regions, cP air masses are characterized by cold temperatures and low humidity.
    • Maritime Tropical (mT): These air masses form over warm and moist oceanic regions. They are characterized by warm temperatures and high humidity.
    • Maritime Polar (mP): Originating over cold oceanic regions, mP air masses are characterized by cool temperatures and high humidity.
    • Continental Arctic (cA): cA air masses originate over extremely cold Arctic regions. They are characterized by frigid temperatures and very low humidity.

  • Characteristics of Air Masses:
    • Air masses originate over vast flat surfaces having uniform temperature and humidity.
    • Air masses travel slowly over hundreds of kilometers from their source regions.
    • As the air masses move away from source regions their chief characteristics of temperature and humidity undergo large-scale changes.
    • They affect the weather conditions of the areas visited by them.
    • When two air masses of different temperature and humidity approach each other, they do not intermingle but a front is formed between them.
      • Weather conditions change abruptly at the front.
      • The front keeps two approaching air masses separate from each other.

CAR-T Cell Therapy

Source: IE

Why in News?

Following India’s approval of CAR-T cell therapy, a pioneering treatment for cancer, a patient recently underwent the procedure, achieving freedom from cancer cells, marking a significant advancement in cancer treatment accessibility in the country.

What is CAR-T Cell Therapy?

  • About: CAR-T cell therapy, also known as chimeric antigen receptor T-cell therapy, is a type of immunotherapy that uses a patient's own immune system to fight cancer.
    • CAR T-cell therapy has been approved for leukaemias (cancers arising from the cells that produce white blood cells) and lymphomas (arising from the lymphatic system).
    • CAR-T cell therapies, often referred to as 'living drugs’.
  • Procedure: It is a complex and personalised treatment process that involves:
    • Collecting T cells: T cells, a type of white blood cell that helps fight infection, are extracted from the patient's blood through a process known as Apheresis.
    • Genetic Engineering: In the laboratory, the T cells are genetically modified to express a special protein called a chimeric antigen receptor (CAR) on their surface.
      • This CAR is designed to recognize and bind to a specific antigen (marker) found on cancer cells.
    • Expansion: The engineered T cells are multiplied in large numbers in the lab.
    • Infusion: The expanded CAR-T cells are then infused back into the patient's bloodstream, where they can identify and attack cancer cells that express the targeted antigen.

  • Development in India: NexCAR19, an indigenously developed therapy for B-cell cancers, has been collaboratively developed by ImmunoACT, Indian Institute of Technology Bombay (IIT-B), and Tata Memorial Hospital.

  • Potential Benefits of CAR-T therapy
    • High Remission Rates: For some patients with advanced cancers who have not responded to other treatments, CAR-T therapy can lead to high rates of complete remission.
    • Personalised Approach: The therapy is tailored to each individual patient's cancer, making it a highly targeted treatment.
  • Potential Risks:
    • Severe Side Effects: CAR-T therapy can cause serious side effects, including cytokine release syndrome (a widespread activation of the immune system and collateral damage to the body’s normal cells) and neurological symptoms (severe confusion, seizures, and speech impairment).
    • High Cost: CAR-T therapy is a very expensive treatment.
