UPSC Exam Relevance: GS 2– Polity and Governance 

Context: SCoS was tasked with advising on survey methodologies, sampling designs, and data tabulation plans for statistical surveys conducted by the government.

Why in news

  • The recent dissolution of the Standing Committee on Statistics (SCoS), led by Pronab Sen, has sparked concerns and criticisms, particularly over its timing and the reasoning provided.

Key Highlights 

Ministry of Statistics and Programme Implementation cited various reasons for dismantling the SCoS.

  1. Overlapping Roles: According to the Director-General of the National Sample Survey Office (NSSO), the SCoS’s functions overlapped with those of the new Steering Committee, formed upon recommendations by the National Statistical Commission (NSC). The new panel, headed by NSC chairman Rajeeva Laxman Karandikar, has already included some SCoS members, reflecting a shift in how the government intends to handle survey-related tasks.
  2. Delay in the Census: The disbandment comes amid concerns raised by SCoS members about the significant delay in conducting the decennial census, last held in 2011. 
  3. The census scheduled for 2021 was postponed due to the COVID-19 pandemic, and no new date has been set. 
  4. This delay has implications for the accuracy and quality of various data sets used for policy-making, as they continue to rely on outdated information from the 2011 census.
  5. Political and Public Reaction: Opposition parties have criticized the government’s decision, suggesting that the dissolution was a response to the committee’s persistent questioning of the delayed census. 
  6. Opposition highlighted the broader implications of this delay, such as the impact on ration benefits under the National Food Security Act and other welfare schemes.
  7. Concerns Over Governance and Data Accuracy: Economists and statisticians have voiced concerns that the decision undermines the advisory role of experts in government data collection and survey methodologies. 
  8. The lack of a recent census hampers evidence-based policy-making, which relies on up-to-date and accurate statistical data.

About NSSO

  • The National Sample Survey Office (NSSO) is an organization under the Ministry of Statistics and Programme Implementation (MoSPI) in India. 
  • It is responsible for conducting large-scale sample surveys across the country on various socio-economic topics. 
  • The data collected by NSSO is crucial for policymaking, economic planning, and assessing the socio-economic conditions of the population.

About Census

  • The census is a crucial exercise that plays a fundamental role in the governance, planning, and development of a country. 
  • In India, the census is conducted every ten years and provides comprehensive data about the population, including its size, distribution, demographic characteristics, and socio-economic conditions.
  • Historical Background: The first systematic and modern census in India was conducted in 1872 during the British rule. However, the first complete census was conducted in 1881, and since then, it has been conducted every ten years without interruption.
  • Conducting Authority: The Census of India is conducted by the Office of the Registrar General and Census Commissioner, India, under the Ministry of Home Affairs. It is one of the largest administrative exercises in the world.
  • The latest census was scheduled for 2021, but it has been delayed due to the COVID-19 pandemic. The previous census was held in 2011.

Conclusion

  • The situation underscores ongoing tensions between the government’s approach to managing statistical bodies and the need for independent advisory committees to ensure the credibility and reliability of national data. The delay in conducting the census remains a critical issue, affecting a wide range of socio-economic policies and planning in India.

Arctic Sea Ice Levels and Their Impact on Indian Monsoon Patterns

Source: The Hindu

https://www.thehindu.com/sci-tech/science/what-role-does-arctic-sea-ice-play-in-indian-monsoon/article68600899.ece/amp/

UPSC Exam Relevance: GS 3– Climate Change

Context: Recent research has highlighted how changes in Arctic Sea ice levels can significantly impact Indian monsoon patterns, leading to unpredictable and extreme weather conditions.

Why in news 

  • The study, conducted by India’s National Centre for Polar and Ocean Research (NCPOR) and South Korea’s Korea Polar Research Institute, provides critical insights into the complex relationship between Arctic Sea ice and the Indian Summer Monsoon Rainfall (ISMR).

Key Findings:

Influence of Arctic Sea Ice on Monsoon: 

  1. The study reveals that a decrease in sea ice in the central Arctic leads to less rainfall in western and peninsular India but increases rainfall in central and northern India. 
  2. Lower sea ice levels in the Barents-Kara Sea region can delay the monsoon’s onset and make it more erratic.

Mechanisms Behind the Influence:

  • Lower sea ice in the central Arctic triggers cyclonic circulation patterns, enhancing Rossby waves and influencing atmospheric conditions over India.
  • High pressure regions form over northwest India and the Mediterranean, strengthening the Asian jet stream and shifting the subtropical easterly jet northward, altering rainfall distribution.
  • Reduced sea ice in the Barents-Kara Sea results in anticyclonic circulation, influencing weather patterns over Europe and subtropical Asia, which affects the Indian monsoon.

Role of Climate Change: 

  • The study underscores that climate change, by accelerating the reduction of Arctic sea ice, exacerbates the variability of the ISMR. 
  • This leads to an increased frequency of droughts in some regions and excessive rainfall and flooding in others, highlighting the urgent need for enhanced climate research and more accurate monsoon forecasts.

Implications for India:

  • Disaster Management: Understanding these dynamics is crucial for improving India’s preparedness for extreme weather events, which have already caused significant loss of life and property, as seen in recent floods in Andhra Pradesh and Telangana.
  • Policy Formulation: This research can inform policymakers on the importance of international cooperation in climate action and the need for adaptive strategies in agriculture, water management, and urban planning.
