Sub-categorisation of Scheduled CastesSyllabus: GS2/Polity and Governance; Government Policy and InterventionContext
  • The Union government has formed a committee to ensure equitable distribution of benefits to Scheduled Castes (SCs) across the country.
    • The sub-categorisation of SCs comes after the Prime Minister’s promise to look into the demand raised by the Madiga community of Telangana.
  • Sub-Categorisation within Scheduled Castes
  • It is to identify and help the most backward among the SCs.In the last two decades, multiple states like Punjab, Bihar, and Tamil Nadu have tried to bring in reservation laws at the state level to sub-categorise SCs.In the last two decades, States like Punjab, Bihar, and Tamil Nadu have tried to bring in reservation laws at the State level in a bid to sub-categorise Scheduled Castes.
  • Legality of Sub-categorisation
  • E. V. Chinnaiah v State of Andhra Pradesh (2004): The Supreme Court through its  5-Judge Bench held that once a community is included in the Presidential List for Scheduled Castes under Article 341 of the Constitution, they become part of a single larger class of people, casting a wide net for the purposes of reservation.
    • It held that the State did not have the legislative power to create sub-classifications within this single class and that such an action would violate the Right to Equality.
    However, all plans are held up in courts as the Supreme Court forms its larger Constitution Bench (in Davinder Singh Case) to decide the matter.
    • The issue of sub-classification in reservations has been pending before a 7-Judge Constitution Bench for nearly two years without a hearing.
  • Arguments favouring sub-categorisation within Scheduled Castes
  • Graded Inequalities: The principal argument for sub-categorisation of SCs has been the graded inequalities among SC communities.
    • The thrust of it has been that even among the marginalised, there are communities that have lesser access to basic facilities.
    Unequal Representation: Some communities are more backward and have less representation than others.
    • For instance, the Madiga community has claimed that the benefits, including that of reservation, meant for the SC category had been cornered by the Mala community, with the Madigas being left out.
    Legal Standpoint: A five-judge Bench headed by Justice Arun Mishra has affirmed the competence of the States to give preferential treatment to the weakest among the Scheduled Castes without depriving other castes of any benefit.
    • The Court has noted that the Scheduled Castes list contains many castes and cannot be treated as a homogeneous group.
    Equitable Distribution of Benefits: The Union government has formed a committee of Secretaries to evaluate and work out a method for the equitable distribution of benefits, schemes, and initiatives to the most backward communities amongst the over 1,200 Scheduled Castes across the country.Committees for Sub-categorisationCommittee of Secretaries: It is a five members committee comprising the Secretaries of the Home Ministry, Law Ministry, Tribal Affairs Ministry, and Social Justice Ministry and it is chaired by the Cabinet Secretary.Mandate: To look at strategies like special initiatives, focusing existing schemes towards them, etc.The Committee needs not to deviate into policy matters like reservation or break-up of SC quota for employment and education.There is no deadline given to present its findings. However, it has been asked to do so at the earliest.Previous Commissions:Justice P. Ramachandra Raju Commission (1996)National Commission (2007)
  • Arguments against sub-categorisation within Scheduled Castes
  • These are primarily based on the legal and practical challenges associated with it.Legal Challenges: The Supreme Court held that the State did not have the power to unilaterally sub-categorise communities in the list of SCs or Scheduled Tribes (STs).
    • The Constitution has provided that these lists can only be made by Parliament and notified by the President.
    Data of socio-economic status: The population data related to SC, ST, and OBC categories are not updated since the 2011 census.
    • It hampers the objective and scientific basis for sub-categorisation.
    Untouchability: The social and educational backwardness cannot be applied to Scheduled Castes and Scheduled Tribes. The special treatment is given to the SCs due to untouchability with which they have suffered since ages.Scheduled Castes in IndiaAs per the 2011 Census, the total population of SCs in India is 16.6% (16.2% in 2001 Census) of the total population of India.Article 341 of Constitution of India defines Scheduled Caste with respect to any State or Union Territory.Constitutional ProvisionsArticle 14: Guarantees equality before law.Article 15 (4): The state is empowered to make any special provision for the advancement of any socially and educationally backward classes of citizens or for the scheduled castes.Article 16(4), 16 (4A) and 16 (4B): Provide for reservation in posts and services.Article 17: Untouchability stands abolished and its practice in any form is forbidden.Article 23: It emphasises the importance of protecting individual freedom and dignity.Article 24: It prohibits the employment of children below the age of 14 years in any factory, mine, or hazardous occupation.Article 46: Promotion of educational and economic interests of Scheduled Castes, Scheduled Tribes and other weaker sections.Article 330: Reservation of seats for Scheduled Castes and Scheduled Tribes in the House of the People.Article 335: It permits laws that reduce the requirements or relax qualifications for members of SC/ST communities in appointments to public services and posts.Other Statutory ProvisionsRFCTLARR Act, 2013: Special provisions have been made for Scheduled Castes and Scheduled Tribes under Sections 41 and 42 of the RFCTLARR Act, 2013 which protect their interests.Scheduled Castes and Scheduled Tribes (Prevention of Atrocities) Act, 1898: This legislation was designed to provide a measure of protection to Scheduled Castes and Scheduled Tribes and to enforce their rights.
  • Conclusion
  • The Constitution of India does not prohibit the Parliament to sub-categorise SCs but it needs to justify by the government that this move would be a 100% count of all castes – a caste census of each community and sub-community and their respective socio-economic data. The government should focus on the equitable distribution of benefits, schemes and initiatives to SCs population in India, as mandated by the Constitution and other Statutory provisions.
  • Source: THIran-Pakistan ConflictSyllabus:GS2/International RelationsContext
  • Pakistan has launched missile strikes into Iran under Operation Marg Bar Sarmachar (Death to Insurgents), following Iran’s missile strikes in Pakistan.
  • Where is Balochistan?
  • Balochistan is a region with a distinct cultural and historical identity, divided between three countries: Pakistan, Iran and Afghanistan.
    • The 909-km Iran-Pakistan border, known as the Goldsmith Line, stretches from a tripoint with Afghanistan to the northern Arabian Sea. 
    The region takes its name from the Baloch tribe. Roughly 9 million ethnic Baloch live on either side of the line, in the Pakistani province of Balochistan, and the Iranian province of Sistan and Baluchestan. The largest portion of the region is in south-western Pakistan. It is Pakistan’s largest province, comprising 44% of the total landmass.
    • It is arid, and the country’s least inhabited and least economically developed region.
  • Issues of Balochistan
  • Economic issues: The people of Balochistan had long felt their region was neglected in terms of development and political representation, fuelling resentment towards the ruling establishment.Political issues: In Pakistan, the Baloch are an ethnic minority physically and politically distant from the Punjabi-dominated regime and also in Iran, the majority-Sunni Baloch are a religious minority who have been persecuted by the state.Demand for separate state: Their marginalization in both countries in subsequent years fuelled several separatist movements for a “Greater Balochistan” nation state.
  • Militant groups involved
  • Jaish Al-Adl (JAA): The Sunni separatist militant group operates freely from Balochistan and is fighting for independence in Iran’s Sistan and Baluchestan province. Baloch Liberation Front and Baloch Liberation Army: Both are Iran-based hideouts of two Baloch militant groups deemed as “terrorist organizations” by Pakistan.
  • Relations Between Iran and Pakistan
  • Before the 1979 Islamic Revolution in Iran, both countries were firmly allied to the United States.In 1955, both of them joined the Baghdad Pact, later known as the Central Treaty Organization (CENTO), a military alliance modeled on NATO.However an ultra-conservative Shiite regime took power in Iran and Sunni -majority Pakistan was undergoing its own Islamisation under military dictator Gen Zia-ul-Haq. In this way the two countries found themselves at opposite ends of the sectarian divide.The Baloch militant insurgency has been a long-running source of tensions between Pakistan and Iran. Both the nations often accused each other of harboring separatist terrorists.
  • India’s Stakes in the region
  • Traditionally India has stayed neutral in the conflicts within the Middle East. However, the fragility of the Baloch frontier, China’s strategic presence in Balochistan along with growing role in the Gulf are of deep concern to India. Also India has invested in Chabahar port lying the Makran coast of Sistan and Baluchistan Province is of concern for India.
  • Source: IEScience Communication in IndiaSyllabus: GS1/Society, GS3/Science and TechnologyIn Context
  • Coverage was an exemplar of the public communication of advanced science.
  • What is Science Communication?
  • Science communication involves all forms of communication around science, scientific work, its outcomes, discussions on its ethical, societal, or political impacts, and direct conversations with scientists as well as diverse audiences. ‘Science communication’ is an umbrella term that also includes the exchange of scientific knowledge, institutional outreach, and public engagement with science.
  • Role of Science Communication for Society in India
  • During the COVID-19 pandemic, even as governments implemented disaster management laws, the States’ as well as experts’ communication of scientific and healthcare-related information became significant.
    • Science communication in a pandemic is intended to promote public compliance with good ‘pandemic habits’ like physical distancing, masking, and vaccination.
    It will help science and scientific cultures penetrate India’s diverse society, and to transform it into a nation of scientific thinking and scientifically aware people.It is an effective  tool for extending scientific boundaries and gaining wide public support for important research and development, which are indispensable for society’s development.
  • Government Initiatives to Encourage Scientific Communication
  • In 1951, the government established the Publications & Information Directorate (PID) under the Council of Scientific and Industrial Research (CSIR).
    • The PID published the national science magazines Vigyan Pragati (Hindi), Science Reporter (English), and Science Ki Duniya (Urdu).
    The government followed up with an attempt to define India’s scientific heritage and the cause of promoting science education through the Birla Industrial and Technological Museum in Calcutta in 1959. In 1976, Parliament passed the 42nd amendment to the Constitution.
    • This included Article 51 A(h) which states “It shall be the duty of every citizen of India to develop a scientific temper, humanism and the spirit of enquiry and reform.”
    The sixth Five Year Plan (1980-1985) promoted the need to popularise science and nurture scientific thinking in India, and established the National Council for Science and Technology Communication (NCSTC)In 1989, the Department of Science and Technology set up Vigyan Prasar, an autonomous organisation to popularise science at large.Modern Scenario: In 2021, the government set up the CSIR-National Institute of Science Communication and Policy Research (CSIR-NIScPR) by merging two previous institutions.
    • Nearly all national science funding agencies have science communication divisions, which issue press releases, conduct social media campaigns, and garner support for exhibitions, popular lectures, etc.
  • How India can Improve Science Communication?
  • Training: Scientists should be trained in the art of science communication while journalists must be oriented towards at least the basic understanding of sciences and its methodology. Degree Programmes: Expanding science communication degree programmes in India at the masters’ and doctoral levels could support training and research in the field.
    • This will also lead to a trained cadre of science communicators with an informed understanding of the needs, perspectives and the consequences of their work in diverse educational, linguistic, and cultural contexts in the country.
    Recognising Scientists: Rewarding scientists for communicating science, nourishing public engagement, and translating research papers to regional languages.Creating Platforms: More platforms should be created to engage scientists and media practitioners to have close dialogues on issues pertaining to scientific developments.Large-scale science communication strategy: This could start with a professional organisation with experts from many fields that works closely with government-level science departments and offices.
    • These frameworks will have to cut across disciplines – of science, medicine, disaster-management, national security, and diplomacy groups as well as media formats.
  • Way Ahead
  • Given the role of scientific solutions to national challenges – such as antimicrobial resistance, air pollution, and energy diversification – India needs a large-scale science communication strategy. When the journalists and the scientific community exchange communication on issues related to science, it creates a mutual understanding, which in turn yield positive outcomes. More seriously planned agenda and policies for science communication in a truly transparent manner are a pre-requisite to engage and speed-up science communication.

  • The Kashmir Valley and Ladakh are experiencing an unusual and severe dry spell (lack of snowfall) this winter.
  • About
  • Snowfall is crucial for the local climate, winter crops and horticulture, availability of waters in streams and rivers, and for the local economy.One of Kashmir’s main winter tourism attractions, Gulmarg, has been bereft of snow this season.
    • Gulmarg is one of Asia’s largest and highest ski resort towns.
  • Reasons 
  • Western Disturban ces: Winter precipitation in the Himalayan region is caused mainly by Western Disturbances, which have been showing a declining trend in recent times.
    • This season there was one feeble western disturbance event in December that did not bring any rains, and another similar one in January.Western Disturbances typically originate as low-pressure systems or cyclones over the Mediterranean Sea. As they move eastwards, they bring significant changes in weather conditions over the Indian subcontinent.
    Temperature Rise: The temperature in the regions is rising. For example, Kashmir’s Srinagar temperature on many days are comparable to those of Delhi, sometimes they appear to be even higher.El Nino: It has affected the global atmospheric circulation, and might be contributing to the deficit precipitation in the region as well.
  • Impacts
  • Short term implications:  A dry spell can result in an increase in forest fires, agricultural drought, and a drop in crop production. It can also lead to an early spring, which can cause a reduction in yield.Long-term implications: It includes the generation of less hydroelectricity, an increase in the rate of glacier melting, and an adverse impact on the drinking water supply, since scanty snowfall means very little recharge of groundwater.
