  • Basmati Rice Revolution: From Crop to Cuisine

    basmati

    Central Idea

    • While scientific research often seems distant from practical outcomes, some less-celebrated success stories stand out.
    • One such triumph is the transformation of India’s basmati rice industry, driven by scientists at the Indian Agricultural Research Institute (IARI) in New Delhi.

    About Basmati Rice

    • Basmati rice is a fragrant, long-grain rice variety primarily cultivated in the Indian subcontinent.
    • It is native to the foothills of the Himalayas in India and Pakistan.
    • Basmati rice is characterized by its long, slender grains that elongate further when cooked.
    • Basmati rice is renowned for its natural aromatic fragrance, often described as nutty or floral.
    • There are different Basmati rice varieties, each with its unique characteristics. Some popular varieties include Basmati 370, Basmati 386, and Basmati 1121.
    • Basmati rice from certain regions, particularly Indian Basmati, has received Geographical Indication (GI) tags, indicating its specific geographical origin and quality.

    [a] First Revolution

    • Traditional Basmati Varieties: Until the late 1980s, Indian farmers primarily cultivated traditional basmati varieties with tall plants prone to lodging, resulting in low yields and long cultivation periods.
    • Breakthrough with PB-1: In 1989, the IARI introduced Pusa Basmati-1 (PB-1), a crossbreed that combined traditional basmati grain attributes with high-yielding traits. PB-1 was more compact, sturdy, and offered improved yields and maturity times.

    [b] The Second Revolution

    • PB-1121’s Quality: The real revolution came in 2003 with the release of Pusa Basmati-1121 (PB-1121), which offered a different advantage. While yielding slightly less, it boasted exceptional grain quality, with elongated kernels that expanded impressively upon cooking.
    • Market Impact: PB-1121’s grain quality allowed companies like KRBL Ltd. to create a lucrative export brand, making it a global favourite. This variety significantly contributed to India’s basmati rice exports.

    [c] Third Revolution

    • PB-1509: In 2013, the IARI introduced Pusa Basmati-1509 (PB-1509), a high-yielding variety with a shorter maturity period. This innovation allowed farmers to cultivate an extra crop, enhancing their economic prospects.
    • Diverse Crop Combinations: PB-1509’s early maturity has enabled farmers to explore crop diversification, including potatoes, sunflowers, sweet corn, and onions, in addition to basmati rice.

  • Reforms and Concerns: The CEC and Other EC Bill, 2023

    cec bill

    Central Idea

    • After being passed in the Rajya Sabha on August 10, the Chief Election Commissioner and Other Election Commissioners (Appointment, Conditions of Service and Term of Office) Bill, 2023, has now moved to the Lok Sabha for approval.

    CEC and Other EC Bill, 2023

    • Objective: To amend constitutional provisions that currently equate Election Commissioners with Supreme Court judges, as well as addressing recent judicial rulings.

    Key Provisions of the Bill

    • Salary and Service Conditions: The Bill proposes to align the salary, allowances, and service conditions of the Chief Election Commissioner (CEC) and the two Election Commissioners with those of a Cabinet Secretary.
    • Repealing the 1991 Act: The Bill’s passage would lead to the repeal of the Election Commission Act of 1991, where Election Commissioners enjoyed parity with Supreme Court judges in terms of remuneration.
    • Potential Impact: While the stipulated salaries for Supreme Court judges and Cabinet Secretaries are similar, Supreme Court judges receive additional post-retirement benefits, raising concerns about the increased bureaucracy’s potential impact on the authority and independence of Election Commissioners.

    Challenges to Independence

    • Shifting Authority: The Election Commission’s primary role involves overseeing, directing, and controlling elections, as defined in Article 324 of the Constitution. Concerns arise that this control may shift if Election Commissioners, now equivalent in rank to Cabinet Secretaries, attempt to discipline Union Ministers for electoral violations.
    • Current Status: Presently, when commissioners summon government officials, their orders are perceived as carrying the authority of a Supreme Court Judge, a status that may change if they are seen as equals to Cabinet Secretaries.

    Preserving Independence and Equivalence to SC Judges

    • Constitutional Safeguards: Article 324 (5) of the Constitution specifies that a CEC can only be removed in a manner similar to that of a Supreme Court judge, safeguarding the independence and equivalence of Election Commissioners to Supreme Court judges.
    • Previous SC Ruling: The Bill also seeks to constitute a committee comprising the Prime Minister, Leader of the Opposition in the Lok Sabha, and a Cabinet Minister nominated by the PM to select Election Commission members. Notably, this committee excludes the CJI, in contrast to a top court ruling from March 2023.

    Background: The SC Ruling

    • Committee Formation: In March 2023, a five-judge Supreme Court bench unanimously ruled that a committee consisting of the Prime Minister, Leader of the Opposition in Lok Sabha, and the Chief Justice of India (CJI) should select the Chief Election Commissioner (CEC) and Election Commissioners (ECs).
    • Founding Principles: The ruling emphasized that India’s founding fathers did not intend for the executive to exclusively dictate appointments to the Election Commission, striving for a more balanced selection process.
    • PIL Origins: The case originated from a PIL filed in 2015, challenging the constitutionality of the President appointing ECI members based on the PM’s advice.

    Impact on the 1991 Act

    • Bill’s Amendment: The Bill aims to repeal the 1991 Act, which previously ensured that the CEC and ECs received salaries equivalent to Supreme Court judges.
    • Revised Equality: Section 10 of the Bill specifies that the salary, allowances, and service conditions of the CEC and ECs will match those of the Cabinet Secretary, marking a departure from the 1991 Act’s provisions.

    Various Concerns Raised

    • Autonomy of the Election Commission: Concerns exist due to the selection panel’s composition, which includes a Cabinet Minister nominated by the Prime Minister instead of the CJI.
    • Unanimous Decisions: Suggestions for unanimous committee decisions aim to address one-sided decision-making concerns.
    • Constitutional Validity: Critics argue the Bill violates democratic principles.
    • Conflicting SC Judgment: The Bill diverges from the Supreme Court’s ruling on the importance of an independent committee in selecting Election Commissioners.
    • Past Electoral Integrity: Some believe Indian elections have been generally fair despite government involvement in Election Commissioner appointments.
    • Consistency in Decision-Making: Concerns have been raised about the Commission’s decision consistency regarding Model Code of Conduct violations.
    • Timing of Election Announcements: Questions surround election announcement timing in relation to government programs, raising concerns about political influence.

    Conclusion

    • Balancing Reforms: The Bill reflects efforts to reform election administration but raises concerns about preserving the Election Commission’s independence and its equivalence to Supreme Court judges.
    • Evolution of Selection Process: The ongoing debate highlights the evolving process of selecting Election Commissioners, aiming to ensure fair and transparent appointments while safeguarding the institution’s autonomy.

  • Supreme Court’s Integration with the National Judicial Data Grid

    National Judicial Data Grid

  • Why Dominant Caste are Demanding Reservation in India?

    maratha quota

    Central Idea

    • A Maratha activist has been on a 17-day hunger strike demanding reservation for the Maratha community in jobs and education.
    • The demand for a Maratha quota is expected to gain momentum as Lok Sabha and Assembly elections approach.

    Historical Context of Maratha Reservation Demand

    • Maratha Background: The Marathas, historically identified as a “warrior” caste, comprise mainly peasant and landowning groups, constituting nearly one-third of Maharashtra’s population. They have been a politically dominant community in the state.
    • Demand for Reservation: The demand for Maratha reservation dates back to the early 1980s when Mathadi Labour Union leader Annasaheb Patil led the first protest rally in Mumbai.

    Recent Developments

    • OBC Status: The Marathas seek to be identified as Kunbis (Farmers), which would entitle them to benefits under the quota for Other Backward Classes (OBCs). This demand arose after the Supreme Court, in May 2021, struck down the quota for Marathas under the state’s Socially and Educationally Backward Class (SEBC) Act, 2018.
    • Bombay High Court Decision: In June 2019, the Bombay High Court upheld the Maratha quota under the SEBC Act but reduced it to 12% in education and 13% in government jobs, in compliance with the 50% reservation limit set by the court.
    • Supreme Court Ruling: In May 2021, the Supreme Court declared the Maharashtra law providing reservation to Marathas unconstitutional, citing it breached the 50% reservation cap set in the Indra Sawhney (Mandal) judgment of 1992.
    • Impact on EWS Quota: Following the SC’s decision on the 10% quota for Economically Weaker Sections (EWS), the Maharashtra government stated that poor Marathas could not benefit from the EWS quota until the Maratha reservation issue was resolved.
    • Government Response: In response to protests and clashes, the government issued a Government Resolution (GR) promising Kunbi caste certificates to certain Maratha community members and referred to an older GR from 2004 pledging reservation for eligible Maratha-Kunbis and Kunbi-Marathas.

    OBC Opposition to Maratha Demand

    • OBC Organizations: OBC organizations have opposed the Maratha demand for OBC reservations due to quota shrink. They argue that Marathas, as a dominant community, should not share the OBC quota, which is already limited in Maharashtra compared to the national quota.
    • Reservation Distribution: Currently, reservations in the state are divided among various categories, including Scheduled Castes, Scheduled Tribes, OBCs, Special Backward Classes, and others.

    Political Impact

    • Polarization: The Maratha reservation issue has led to a sharp Maratha-OBC polarization in politics. Traditionally, Marathas leaned towards the Congress and NCP, while the BJP and Shiv Sena garnered OBC support.
    • Changing Dynamics: Recent political developments, including splits within parties and alliances, have complicated the political landscape, making the issue even more complex.

    Conclusion

    • The Maratha reservation issue remains a highly contentious and politically charged topic in Maharashtra, with implications for both social and political dynamics in the state.
