    Which major challenges to India’s services and manufacturing sectors? 

    As per the industry leaders and NASSCOM’s 2025 Strategic Review report, the major challenges are :

    • Technological Disruption from Artificial Intelligence (AI): AI-driven solutions are transforming traditional business models, reducing revenue from new contracts, and reshaping hiring and training practices. Example: Automation in IT services is reducing the need for entry-level jobs, impacting employment growth.
    • Global Protectionism and Rising Tariffs: Increasing reciprocal tariffs and trade barriers, particularly from major economies like the United States, pose a threat to export-oriented industries. Example: U.S. tariffs on Indian textiles and pharmaceuticals may reduce market competitiveness and profit margins.
    • Slowdown in IT Sector Growth: India’s IT sector growth is expected to be 5.1% in FY25, a decline from its historical 16% CAGR, due to reduced demand and shifting client priorities. Example: Major IT firms report fewer large-scale outsourcing contracts as clients adopt in-house AI solutions.
    • Geopolitical Uncertainty: Geopolitical tensions and supply chain disruptions increase business risks and operational costs. Example: Disruptions in the Red Sea trade route affect electronics and automotive supply chains.
    • Potential U.S. Recession Risk: A U.S. economic slowdown could reduce export demand, significantly impacting both manufacturing and services, as the U.S. is India’s largest trading partner. Example: A U.S. recession may lead to fewer orders for Indian IT services, pharmaceuticals, and automotive components.

    How could the reciprocal tariffs announced by the U.S. impact India’s manufacturing sector?

    • Reduced Export Competitiveness: Higher import duties on Indian goods will increase prices in the U.S. market, making Indian products less competitive against local and other global manufacturers. Example: Indian textile exports to the U.S. could decline as higher tariffs make them more expensive compared to those from Vietnam or Bangladesh.
    • Disruption of Supply Chains: Tariff barriers may affect cross-border supply chains, increasing production costs and causing delays in delivery. Example: Indian automotive components exported to U.S. manufacturers may face disruptions, affecting just-in-time production systems.
    • Reduced Investment and Market Access: Tariffs create uncertainty, discouraging foreign direct investment (FDI) and limiting India’s access to the lucrative U.S. market. Example: Electronics manufacturers considering India as a production hub may shift investments to low-tariff countries to maintain U.S. market access.

    Way forward: 

    • Diversify Export Markets: Strengthen trade ties with emerging economies (e.g., Africa, Southeast Asia) and regional blocs to reduce dependence on the U.S. market.
    • Enhance Domestic Manufacturing Competitiveness: Promote Make in India, invest in advanced technologies, and offer export incentives to reduce costs and improve global market access.

  • Antarctic Circumpolar Current (ACC)

    Why in the News?

    Researchers have found that the Antarctic Circumpolar Current (ACC) is slowing due to melting ice sheets. By 2050, it may weaken by 20%, affecting global climate, ocean circulation, and marine ecosystems.

    What is the Antarctic Circumpolar Current (ACC)?

    • The ACC is the strongest and largest ocean current on Earth.
    • It flows continuously from west to east around Antarctica, acting as a boundary between the Southern Ocean and the Atlantic, Pacific, and Indian Oceans.
    • It flows from west to east, driven by the westerly winds and the Coriolis effect, creating a loop that completely encircles Antarctica.
    • The ACC interacts with several regional currents, such as the Brazil Current, East Australian Current, and Agulhas Current.
    • It is influenced by both westerly winds and polar easterlies, which affect its strength and flow patterns.
    • Key features of the ACC:
      • It is five times stronger than the Gulf Stream and transports 130 million cubic meters of water per second.
      • It plays a crucial role in global heat and nutrient distribution, influencing climate patterns worldwide.
      • It prevents warmer northern waters from reaching Antarctica, helping to preserve the region’s ice sheets.
      • The ACC drives the global conveyor belt, regulating deep ocean currents and heat flow.
      • Its upwelling of nutrient-rich waters sustains Antarctic marine life, including krill, whales, and penguins.

    Why does Antarctic Ice Melt affect ACC?

    • Freshwater Dilution: Melting ice lowers salinity, weakening ocean density gradients that drive the ACC.
    • Slower Heat Exchange: Reduced current strength disrupts global heat distribution, leading to stronger storms and rising sea levels.

    Key Findings of the New Research

    A study by the University of Melbourne and NORCE Norwegian Research Centre, published in Environmental Research Letters, reveals:

    • ACC could slow by 20% by 2050 due to melting ice sheets.
    • Disrupted global climate as a weaker ACC reduces heat distribution, carbon absorption, and weather stability. 
    • Antarctic ecosystem at risk, with invasive species threatening penguins, krill, and whales.
    • Supercomputer simulations confirm that deep ocean circulation is slowing, worsening climate instability.
    • Reducing carbon emissions is crucial to prevent further ice melting and ACC weakening.

  • The academic link between Nepal and India

    Why in the News?

    On February 16, a third-year female student from Nepal died by suicide at Kalinga Institute of Industrial Technology (KIIT) in Bhubaneswar.

    What were the reasons behind the protests by Nepali students at KIIT, Bhubaneswar?

    • Harassment and University Inaction: Nepali students protested after a third-year Nepali woman student died by suicide, allegedly due to harassment by a male student. Despite multiple complaints, the university failed to take action. Example: The deceased student had repeatedly reported the harassment to university authorities, but no substantial steps were taken to address her concerns.
    • Forced Campus Eviction: KIIT ordered Nepali students to vacate the campus following the protests, which was viewed as an unjust punishment against the entire community. Example: Instead of addressing the harassment claims, the university’s eviction order further alienated Nepali students, leading to greater unrest.
    • Demand for Justice and Fair Treatment: Students sought accountability for the harassment and fair treatment under the Indo-Nepal Peace Treaty of 1950, which ensures equal rights for Nepali citizens in India. Example: Protesters argued that the eviction violated Articles 6 and 7 of the treaty, which guarantee the right to residence and fair treatment.

    Why is Nepal’s education system being influenced by the colonial legacy of British India?

    • Affiliation with Indian Universities: Nepal’s first college, Tri-Chandra College (established in 1918), was affiliated with Indian universities (Calcutta and later Patna University), controlling courses, pedagogy, and examinations.
    • Dependence on Indian Instructors: Early instructors in Nepal’s education system were trained in Indian universities, leading to the adoption of Indian academic frameworks.
    • Limited Domestic Higher Education: Until Tribhuvan University was established in 1959, Nepal lacked postgraduate education, forcing students to seek higher education in India.
    • Colonial Curriculum: The content of education remained heavily influenced by British India’s system, limiting the development of Nepal-centric academic discourse.
    • Post-1950 Reforms: Efforts like the National Educational Planning Commission (1954) and New Education System Plan (1971) aimed to “Nepalise” the system, yet the intellectual field continued to be shaped by Indian education.

    In what way is the KIIT incident linked to the Indo-Nepal Peace Treaty of 1950, especially Articles 6 and 7?

    • Violation of Equal Treatment (Article 6): Article 6 of the Indo-Nepal Peace Treaty ensures that citizens of Nepal and India receive “national treatment” in each other’s territories. The directive for Nepali students to vacate the KIIT campus violated this provision by treating them differently based on their nationality.
    • Infringement on the Right to Residence (Article 7): Article 7 grants Nepali citizens the right to reside in India without discrimination. KIIT’s order to vacate the premises directly infringed on this right, as it targeted Nepali students exclusively.
    • Impact on Educational Access (Article 7): The Treaty allows Nepali citizens to pursue education in India without barriers. The disruption of academic activities and the evacuation order restricted their educational access, breaching this provision.

    Way forward: 

    • Strengthening Institutional Accountability: Ensure universities establish robust grievance redressal mechanisms to address harassment complaints promptly and impartially. Independent inquiry committees should be set up to investigate incidents, ensuring transparency and justice.
    • Upholding Treaty Commitments: Indian institutions must align their policies with the Indo-Nepal Peace Treaty, guaranteeing equal treatment and the right to residence for Nepali students. Regular dialogue between Indian and Nepali authorities can help prevent future violations.
