[UPSC 2019] Are we losing our local identity for the global identity? Discuss
Linkage: The tension between globalising forces and national or local identities, which is at the heart of the debate surrounding the political trilemma, particularly the interplay between international economic integration and national sovereignty/popular democracy. |
Mentor’s Comment: Democracies in the West are facing a crisis marked by increasing polarization, mistrust in institutions, and rising populism, leading to more insular policies. Economist Dani Rodrik’s “political trilemma” suggests countries can only have two of three things: global economic integration, national sovereignty, and popular democracy. Despite globalization, nations have imposed trade barriers, limiting its benefits.
Today’s editorial examines the growing polarization, distrust in institutions, and the rise of populism, which are driving countries towards more insular policies despite globalization. This topic is relevant for GS Paper 1 on Society and GS Paper 2 on Polity in the Mains exam.

What was once just a concept in academic studies is now happening around the world, with its effects being more noticeable in Western countries than in others.
How has globalization impacted sectors and populations in Western countries, fueling populism?
- Job Losses in Manufacturing: Outsourcing of jobs to lower-cost countries has led to job losses in traditional sectors like steel and textiles, especially in regions like the U.S. Rust Belt, fueling populist sentiments. Eg: The U.S. steel industry decline and its role in Donald Trump’s 2016 campaign.
- Economic Inequality: Globalization has widened the gap between prosperous urban elites and struggling rural populations, contributing to resentment and populist support. Eg: The Brexit vote, with economically disadvantaged areas pushing for leave due to perceived inequality.
- Cultural and Identity Concerns: The movement of people and ideas has raised fears of cultural dilution, driving anti-globalization and nationalist rhetoric. Eg: The rise of far-right parties in Europe, like the National Rally and AfD, focusing on immigration and national identity.
What are the three choices in balancing democracy, sovereignty, and globalization, according to Rodrik’s trilemma?
- Democracy + Globalization, but Ceding Sovereignty: Countries embrace democratic participation and global economic integration but surrender some national sovereignty. Eg: The European Union (EU), where countries gave up control over key areas like trade and migration for economic benefits, leading to nationalist backlash, such as Brexit.
- Globalization + Sovereignty, but Restricting Democracy: Countries maintain sovereignty and integrate into the global economy but limit democratic influence on economic decisions, often relying on technocratic governance. Eg: IMF-imposed austerity measures in countries like Kenya, which prioritized fiscal stability over popular democracy, leading to public dissatisfaction.
- Democracy + Sovereignty, but Limiting Globalization: Countries preserve both sovereignty and democracy but restrict the extent of globalization, often through protectionist policies. Eg: India’s approach of using protectionism and selective foreign investment to balance globalization with domestic control, ensuring political stability and sovereignty.
|
How have China and India managed their economies through selective globalisation?
- Controlled Foreign Investment: Both countries selectively allow foreign investments in specific sectors while restricting or limiting them in others to protect strategic industries. Eg: China has encouraged foreign investments in manufacturing but tightly controls foreign ownership in sectors like media, telecom, and finance. India has similarly promoted foreign direct investment (FDI) in industries like technology but has been cautious in sectors like retail and defense.
- Export-Oriented Growth: Both nations have prioritized export-led growth, using globalization to access international markets while maintaining strong domestic industrial policies. Eg: China’s “Made in China” strategy focused on becoming the global manufacturing hub, while India’s “Make in India” initiative aims to boost domestic manufacturing for export.
- Government Control Over Key Sectors: Both countries retain significant government control over critical sectors, such as banking, energy, and infrastructure, to safeguard national interests. Eg: China’s state-owned enterprises (SOEs) dominate key industries like energy and finance, while India has state-run companies in sectors like oil, railways, and defense.
- Selective Trade Agreements: China and India have negotiated trade agreements that protect domestic industries while opening up others for global competition. Eg: China joined the World Trade Organization (WTO) in 2001 but protected its agricultural sector with subsidies. India has been cautious in committing to trade agreements that might undermine its domestic sectors, like agriculture.
- Managing Political and Economic Sovereignty: Both nations maintain tight political control, limiting the influence of external forces on domestic governance and policy-making. Eg: China tightly controls its political landscape and restricts foreign influence through measures like the “Great Firewall,” while India enforces its sovereignty by regulating foreign content in media and restricting foreign NGOs in sensitive areas.
What consequences have Western democracies faced from balancing free trade, self-determination, and democracy?
- Economic Inequality and Job Losses: Free trade has led to the outsourcing of manufacturing jobs to lower-cost countries, resulting in job losses and economic insecurity for certain segments of the population. Eg: In the U.S. and the U.K., industrial regions like the Rust Belt have seen significant declines in manufacturing jobs due to globalization, contributing to growing economic disparities.
- Rise of Populism and Nationalism: As global competition increased, many voters felt left behind by globalization, leading to the rise of populist and nationalist political movements that prioritize national sovereignty over international cooperation. Eg: Brexit in the U.K. and the election of populist leaders like Donald Trump in the U.S. were fueled by sentiments of reclaiming national sovereignty and resisting the perceived negative impacts of globalization.
- Erosion of Trust in Democratic Institutions: The challenges of balancing democracy with the pressures of globalization have caused frustration among citizens, leading to diminished trust in democratic institutions and the political establishment. Eg: In France, protests like the “Yellow Vest” movement reflect public dissatisfaction with economic policies seen as favoring global markets over local welfare, questioning the legitimacy of institutions and their responsiveness to the people’s needs.
Way forward:
- Balancing Globalization with Domestic Welfare: India must ensure that globalization benefits are equitably distributed, addressing economic insecurity and preventing resentment. Eg: Support local industries and vulnerable sectors through skill development and welfare programs.
- Strengthening Democratic Institutions: India should make democratic institutions more responsive to public concerns, ensuring inclusivity and addressing inequality. Eg: Engage citizens in policymaking to ensure economic policies benefit all.

Why in the News?
The India Meteorological Department (IMD) has predicted that the rainfall during the June-September southwest monsoon season will be higher than usual, around 105% of the average rainfall over a long period.
What are the main factors that influence the Indian monsoon, as mentioned by the IMD?
- El Niño-Southern Oscillation (ENSO): El Niño, which is characterized by warming sea surface temperatures in the Pacific Ocean, tends to reduce monsoon rainfall over India. Eg, during the 2015 El Niño event, India experienced a weakened monsoon and below-normal rainfall.
- Indian Ocean Dipole (IOD): The IOD refers to temperature differences between the western and eastern Indian Ocean. A positive IOD (warmer waters in the west) is typically linked to above-average rainfall in India, while a negative IOD can lead to drought conditions. Eg,2019 saw a positive IOD, which helped counterbalance the El Niño and brought more rainfall.
- Himalayan Snow Cover: As observed by Blanford, the amount of snow accumulation in the Himalayas influences the monsoon. A thicker snow cover in the winter months often leads to increased rainfall during the subsequent monsoon. Eg, years with heavy snowfall in the Himalayas tend to see better monsoon rainfall in regions like Northwest India.
How did Blanford contribute to the development of monsoon forecasting in India?
- Identified the Snow-Monsoon Relationship: Blanford discovered an inverse relationship between the amount of snow accumulated in the Himalayas during winter and the subsequent monsoon rainfall over India. He hypothesized that greater snow accumulation led to a stronger monsoon. This was the basis for early monsoon predictions. Eg: Between 1882-1885, Blanford used Himalayan snow cover data to predict the intensity of the monsoon, marking a key step in systematic weather forecasting.
- First Long-Range Forecast (1886): Blanford made India’s first long-range monsoon forecast in 1886, predicting the seasonal rainfall across India and Burma based on his snow-rain hypothesis. This was a pioneering effort in utilizing long-term data for weather predictions. Eg: Blanford’s 1886 forecast was the first to consider annual snowfall patterns in the Himalayas to predict the monsoon’s arrival and intensity across the entire Indian subcontinent.
- Foundation for Modern Meteorology: Blanford’s work laid the foundation for further development in meteorology and forecasting. His research on snow cover influenced future meteorologists, including Sir John Eliot and Sir Gilbert Walker, who refined and expanded his methods using new data sources and statistical models. Eg: Blanford’s ideas directly influenced later meteorologists, helping to evolve more comprehensive models, including those considering global atmospheric factors.
Why were IMD’s forecasts inaccurate between 1932 and 1987?
- Outdated Predictors: The parameters identified by Sir Gilbert Walker, such as the Southern Oscillation and other atmospheric factors, had lost their significance over time, meaning their relationship with the monsoon was no longer consistent. This led to inaccurate forecasts. Eg: For instance, in the period 1932-1987, the forecast errors were significant, with average errors of 12.33 cm for the peninsula and 9.9 cm for Northwest India, indicating the failure of the existing model.
- Failure to Adapt to New Data: Despite attempts to tweak Walker’s model, the IMD did not fully integrate new meteorological data and evolving atmospheric conditions, leading to persistent inaccuracies in monsoon prediction. Eg: The model failed to predict the 1987 drought, highlighting the inadequacy of the forecasting system during this period and the inability to account for changing atmospheric patterns.
How has the IMD’s forecasting system improved since 2007?
- Introduction of Statistical Ensemble Forecasting System (SEFS): In 2007, the IMD introduced the SEFS, which combined multiple models to generate a more robust prediction. This reduced the error margin and improved the accuracy of forecasts by considering different possible outcomes. Eg: The SEFS helped reduce the average absolute error in forecasts between 2007 and 2018 to 5.95% of the long-period average (LPA), compared to a higher 7.94% error in the earlier period (1995-2006).
- Launch of the Monsoon Mission Coupled Forecasting System (MMCFS): In 2012, the IMD launched the MMCFS, which integrated ocean, atmosphere, and land data for more accurate predictions. This coupled dynamic model enabled better predictions by accounting for the interactions between various climate factors. Eg: The MMCFS contributed to more accurate monsoon forecasts in the years following its introduction, helping the IMD predict monsoon patterns with greater precision.
What impact did the Monsoon Mission Coupled Forecasting System (MMCFS) have on IMD’s accuracy?
- Improved Forecast Accuracy by Integrating Multiple Data Sources: The MMCFS combined data from the ocean, atmosphere, and land, allowing for a more holistic and accurate monsoon forecast. This helped the IMD provide more reliable predictions by considering the dynamic interactions between various climate components. Eg: After the introduction of MMCFS in 2012, the IMD was able to produce more precise monsoon predictions, particularly in terms of seasonal rainfall.
- Enhanced Long-Term Predictive Capabilities: The coupled model allowed the IMD to improve long-term monsoon predictions by simulating real-world climate interactions more accurately, reducing errors in forecasting and enhancing the reliability of predictions over longer time spans. Eg: The model helped improve predictions such as the 2014 monsoon season, where the forecast matched the actual rainfall more closely than earlier years, highlighting its effectiveness in reducing forecast errors.
Way forward:
- Integration of Artificial Intelligence and Machine Learning: Leveraging AI and ML can further refine IMD’s forecasting models by analyzing vast datasets more efficiently and identifying hidden patterns in climate behavior, improving the accuracy of short- and long-term monsoon predictions.
- Collaboration with Global Climate Agencies: Strengthening partnerships with international climate research institutions can enhance data sharing and provide more comprehensive insights into global climate drivers affecting the Indian monsoon.

India’s growing economy has sparked discussions on using arbitration to handle increasing commercial disputes. The overburdened court system makes arbitration a popular choice, but questions remain about its effectiveness.
What are the two key parameters that define the credibility and legitimacy of Indian arbitration?
- Efficient Conduct of Arbitral Proceedings: Arbitrators must manage timelines, procedures, and hearings to avoid unnecessary delays and ensure speedy resolution. Eg: In a construction contract dispute, an arbitrator who ensures hearings happen on schedule and avoids multiple adjournments boosts arbitration credibility.
- Quality of Arbitral Awards: Arbitral awards must be factually accurate, well-reasoned, and legally sound so they can withstand court scrutiny. Eg: In a technology dispute, an arbitrator who carefully analyses technical evidence and explains compensation calculation clearly ensures the award is respected and upheld.
Why has the identification of elite Indian arbitrators primarily with retired judges been seen as a limitation?
- Over-Reliance on Judicial Experience: Assumes judicial skills alone are enough for arbitration, without adapting to arbitration’s flexible needs. Eg: A retired judge may strictly follow civil procedure rules, causing unnecessary delays in arbitration.
- Court-like Procedures in Arbitration: Arbitrations tend to mimic lengthy court processes, losing their speed and efficiency advantage. Eg: Instead of quick hearings, a retired judge-arbitrator may insist on prolonged cross-examinations like a courtroom trial.
- Poorly Reasoned Awards: Awards by some retired judges may lack commercial understanding and detailed reasoning, leading to challenges and setting-aside in courts. Eg: In a business valuation dispute, an arbitrator may issue an award without deeply analysing financial reports, making it vulnerable to appeal.
- Lack of Soft Skills and International Best Practices: Many retired judges are unfamiliar with global arbitration practices and soft skills like consensus-building within a tribunal. Eg: In an international arbitration panel, an Indian retired judge might struggle to navigate cultural differences or informal deliberations.
- Limited Diversity of Expertise: Arbitration needs experts from various fields (engineering, finance, tech), not just law, to handle complex technical disputes. Eg: In a complex infrastructure project dispute, a technical expert-arbitrator could resolve issues faster than a purely legal expert.
Who plays the most decisive role in ensuring the efficiency and quality of arbitral proceedings in India?
- Arbitrators Set the Procedural Framework: They design and enforce the timelines, hearing schedules, and procedural rules to keep the arbitration efficient. Eg: An arbitrator can fix strict deadlines for filing evidence to avoid unnecessary extensions.
- Arbitrators Manage Disputes and Party Conduct: They resolve procedural disputes, manage party behavior, and can impose sanctions for delays or misconduct. Eg: If a party repeatedly seeks adjournments, the arbitrator can impose a cost penalty to maintain discipline.
- Arbitrators Deliver Final, Reasoned Awards: They are responsible for writing high-quality, logical, and well-supported awards that stand strong in judicial review. Eg: In a financial fraud arbitration, a well-reasoned award citing expert evidence and quantifying losses strengthens the award’s credibility.
What are the steps taken by the Indian government?
- Legislative Reforms: Passed the Arbitration and Conciliation (Amendment) Acts (2015, 2019, 2021) to reduce court interference, set strict timelines, and promote institutional arbitration. Eg: Introduction of a 12-month time limit to complete arbitration proceedings.
- Establishment of Institutions: Set up the India International Arbitration Centre (IIAC) in New Delhi to promote institutional arbitration at par with global standards. Eg: IIAC aims to handle both domestic and international arbitrations efficiently.
- Promoting Training and Accreditation: Government encouraged specialized training programs and certifications for arbitrators, including support for professional bodies like the Chartered Institute of Arbitrators (CIArb) India branch. Eg: Collaboration with global arbitration bodies to train Indian arbitrators in international best practices.
|
How can the Indian arbitration ecosystem diversify and improve the quality of its arbitrators? (Way forward)
- Diversify the Pool of Arbitrators: Include not just retired judges and advocates, but also trained professionals from fields like engineering, finance, and technology. Eg: Appointing a financial expert as arbitrator in a complex banking dispute can lead to faster and better-informed decisions.
- Mandatory Training and Accreditation: Every arbitrator, regardless of background, must undergo rigorous training through specialized certificate courses and workshops. Eg: A retired judge attending an international arbitration course learns modern practices like fast-track arbitration and efficient evidence management.
- Promote a Culture of Professional Arbitration: Build an ecosystem where arbitration is seen as a specialized profession, not as a secondary option to court litigation. Eg: Creating prestigious professional associations and ranking systems for arbitrators can motivate continuous learning and excellence.

India has recently expanded its claim in the Central Arabian Sea by nearly 10,000 square kilometers as part of its ‘extended continental shelf,’ modifying an earlier claim to resolve a dispute with Pakistan.
\
About Extended Continental Shelf (ECS):
- ECS refers to the area beyond 200 nautical miles that countries can claim by submitting geological and geophysical evidence to the Commission on the Limits of the Continental Shelf (CLCS).
- These claims allow countries to explore resources like oil, gas, and minerals on and beneath the seabed.
- Coastal states have rights to an Exclusive Economic Zone (EEZ) up to 200 nautical miles from their coastline.
- However, such States can claim additional seabed area beyond this limit if they prove scientifically that the continental shelf extends naturally from their landmass.
Back2Basics: Commission on the Limits of the Continental Shelf (CLCS)
- The CLCS estd. In 1997, is a UN body under the UNCLOS (United Nations Convention on the Law of the Sea) that helps states determine the outer limits of their continental shelf beyond 200 nautical miles.
- The CLCS reviews the scientific data provided by states and makes binding recommendations on the extent of the outer shelf limits.
- The commission comprises 21 experts from geology, geophysics, and hydrography, ensuring legal compliance and peaceful boundary resolution.
|
India’s Modified Claims and Pakistan:
- India first submitted a claim in 2009 for an extended shelf in the Bay of Bengal, Indian Ocean, and Arabian Sea, claiming an additional 1.2 million square kilometers.
- After Pakistan’s objections, India modified its claim, splitting it into two parts to resolve disputes and ensure uncontroversial areas in the Central Arabian Sea.
- India also increased its claim by 10,000 square kilometers using new scientific data.
- The Sir Creek area, a disputed waterway between India and Pakistan, remains a point of contention, but India’s modification aims for peaceful resolution.
- India’s claim overlaps with Oman’s shelf, but the two countries have an agreement to keep the delimitation open without conflict.

Recently, a team of scientists from Germany reported a breakthrough in combating the cucumber mosaic virus (CMV) through an innovative RNA-based antiviral agent.
About Cucumber Mosaic Virus (CMV):
- CMV is one of the most widespread and destructive plant viruses, affecting over 1,200 plant species, including important food crops such as cucumbers, melons, and cereals.
- The virus is transmitted by aphids, tiny insects that spread the virus as they feed on plants, making outbreaks difficult to control.
- In India, CMV causes significant yield losses in crops like bananas, pumpkins, and cucumbers, leading to mosaic discoloration, stunted growth, and unviable fruits.
- The economic impact of CMV includes both direct financial losses from reduced crop yields and the indirect costs of pest management.
RNA Silencing Methods discussed (HIGS vs SIGS):
RNA silencing is a natural defense mechanism that plants use to protect themselves from viral infections.
Two RNA-based technologies, Host-Induced Gene Silencing (HIGS) and Spray-Induced Gene Silencing (SIGS), have been developed to enhance plant immunity against diseases like CMV.
[1] Host-Induced Gene Silencing (HIGS):
- HIGS involves genetically modifying plants to produce dsRNA, which activates the plant’s immune system to fight off the virus.
- This method provides continuous protection and long-term immunity throughout the plant’s lifecycle.
- However, it faces challenges such as regulatory issues, high production costs, and the potential for viruses to evolve resistance over time.
[2] Spray-Induced Gene Silencing (SIGS):
- SIGS, unlike HIGS, does not require genetic modification. Instead, plants are treated with RNA sprays containing dsRNA that targets specific viruses.
- This method is cost-effective, non-GMO, and can be applied to a variety of crops.
- However, SIGS provides short-term protection, may be ineffective due to random RNA mixtures, and its effectiveness can be reduced by environmental factors such as sunlight, rain, and soil microbes.
| [UPSC 2019] RNA interference (RNAi)’ technology has gained popularity in the last few years. Why?
1. It is used in developing gene silencing therapies.
2. It can be used in developing therapies for-the treatment of cancer.
3. It can be used to develop hormone replacement therapies.
4. It can be used to produce crop plants that are resistant to viral pathogens.
