  • Did 250 million Indians exit Poverty?  

    poverty

    Introduction

    • The recent paper by Niti Aayog has highlighted a significant reduction in ‘multidimensional poverty’ among Indians between 2013-14 and 2022-23, an achievement acknowledged by PM Modi.
    • To comprehend this data accurately, it is essential to grasp the concept of multidimensional poverty and evaluate the methodology used.

    Understanding Multidimensional Poverty

    • Traditional Poverty Metrics: Poverty is commonly measured monetarily, based on income or expenditure thresholds.
    • Multidimensional Poverty Index (MPI): India employs a global MPI that assesses poverty by considering 12 life aspects beyond income. These aspects fall under categories like education, health, and living standards.
    • Deprivation Assessment: Households are evaluated for deprivation across each of the 12 indicators. If they are deprived in several areas, they are labelled ‘multidimensionally poor’ (MDP).

    Data Sources

    • National Family Health Surveys (NFHS): Household-level data from NFHS serves as the raw material. Niti Aayog further processes this data to calculate MDP figures.
    • NFHS Rounds: NFHS data is available for three rounds: 2005-06 (NFHS-3), 2015-16 (NFHS-4), and 2019-21 (NFHS-5).
    • Share of MDP Indians: In 2005-06, it was 55%, which decreased to 25% in 2015-16. Assuming a consistent pace, the paper suggests it may have been 29% in 2013-14. Further extrapolation estimates it to be 11% by 2022-23.

    Assessing the Assumptions

    • Vague Starting Point: The choice of 2013-14 as a starting point may be open to interpretation and serves as a defining factor for evaluating nine years of Modi’s leadership.
    • Uniform Pace Assumption: Assuming a uniform pace over such a long period can be challenging, as it may not account for variations in progress over different years.
    • Neglecting Pandemic Impact: Extrapolating progress without considering the pandemic’s effects on data collection and welfare reversals may lead to inaccuracies.

    Interpreting the Data

    • Value of Indices: While indices like MPI offer a combined view of multiple indicators, they should not overshadow the importance of monetary poverty data.
    • Not Equivalent to Poverty: Multidimensional poverty should not be equated with poverty itself, as they represent different aspects. It is essential to differentiate between the two.
    • Selective Maths: The exercise of interpolation and extrapolation to align with a government’s tenure should be viewed critically and with consideration of potential limitations.

    Conclusion

    • The reduction in multidimensional poverty in India is a noteworthy achievement, as evidenced by NFHS data.
    • However, it is crucial to approach such data with a nuanced understanding of the methodology, assumptions, and its implications.
    • While multidimensional poverty indices provide valuable insights, they should complement, not replace, comprehensive poverty assessment methods.

    • In 2014, the Royal Swedish Academy of Sciences declared that “the 21st century will be lit by LED lamps,” recognizing the pivotal role of Light-Emitting Diodes (LEDs) in shaping the future of lighting technology.
    • This article delves into the fascinating world of diodes, LEDs, and their significance in modern technology.

    Understanding Diodes

    • Diode Basics: A diode is a small electronic component with two terminals, an anode and a cathode. Its primary function is to allow current flow in one direction only, thanks to a p-n junction.
    • P-N Junction: A p-n junction consists of two adjacent materials: a p-type with positive charge-carriers called holes and an n-type with negative charge-carriers – electrons. Electrons can flow easily from the n-type to the p-type but not the other way, granting the diode its one-way current control.
    • Anode and Cathode: The anode terminal is connected to the p-type material, while the cathode is connected to the n-type material. These terminals define the diode’s directionality.

    Birth of Light-Emitting Diodes (LEDs)

    • Electroluminescence: LEDs are diodes that emit light. Electrons, with higher energy levels than holes, release energy when they occupy holes in the p-n junction. If this energy falls within the visible spectrum, light is emitted – a phenomenon known as electroluminescence.
    • Band Gap: LEDs achieve specific light colors by ensuring that electron-hole recombination releases a precise amount of energy, determined by the band gap.

    Significance of Band Gap

    • Energy Levels: Electrons can only have distinct energy values and occupy particular energy levels. These electrons tend to occupy the lowest energy levels available, leading to conductors, insulators, and materials with a band gap.
    • Band Gap’s Role: A band gap represents the energy threshold required for electrons to move from lower to higher energy levels, allowing materials to conduct electricity.
    • LEDs and Band Gap: In LEDs, the energy emitted during electron-hole recombination corresponds to the band gap, determining the light’s color.

    LED’s Color Palette

    • Historical Context: Scientists developed red and green LEDs over four decades before achieving blue LEDs. The challenge lay in creating gallium nitride crystals with precise properties for electroluminescence.
    • Primary Colors: LEDs can produce red, green, and blue light, offering a versatile color palette. Combining different LEDs enables a broad spectrum of colors on display boards and screens.
    • Breakthrough: Japanese researchers, Isamu Akasaki, Hiroshi Amano, and Shuji Nakamura, made a significant breakthrough in the late 1980s, creating a bright blue LED using gallium nitride. Their achievement earned them the 2014 Nobel Prize in Physics.

    Advantages of LEDs

    • Efficiency: LEDs outperform incandescent bulbs and fluorescent lamps in terms of luminous efficacy, emitting more light per watt of power.
    • Durability: LEDs are highly durable, reducing material waste and maintenance costs.
    • Diverse Applications: LEDs find applications in diverse fields, from consumer electronics and signage to greenhouse lighting and air quality monitoring.
    • Color Versatility: LEDs can emit various colors and frequencies, catering to a wide range of applications.

    Future Prospects

    • Haitz’s Law: Similar to Moore’s law, LEDs have followed Haitz’s law, predicting cost reduction and increased light output over time.
    • Innovations: Ongoing research explores skin-embedded LEDs, organic LEDs, and efficient LEDs made from perovskites, promising further advancements in lighting technology.
