Incidences of people drowning down into the Mahi River have become more frequent.
AboutMahi River
The Mahi River originates in the Vindhya Range of Madhya Pradesh (hot semi-arid and watershed region), near Dhar.
It flows northward through Madhya Pradesh before turning westward upon entering Rajasthan. It then moves southwest, passing through Gujarat, and eventually empties into the Arabian Sea.
The river stretches for about 580 kilometers.
Soil Type: The Mahi River Basin consists of Deep Black soil(southern region) and Alluvial soil(northern region).
Major Tributaries: the Som, the Anas, the Panam, and the Goma.
Major Dams: Kadana Dam and the Mahi Bajaj Sagar (Banswara) Dam are significant hydroelectric and irrigation projects on the Mahi River.
Biodiversity: Supports diverse flora and fauna, including endangered species like the Indian Skimmer and Gharial.
Key Features:
It is surrounded by the Aravalli Hills to the north and northwest, the Malwa Plateau to the east, the Vindhyas to the south, and the Gulf of Khambhat to the west.
One of the most notable features of the Mahi River is its crossing of the Tropic of Cancer twice; once in Madhya Pradesh and again near the Gujarat-Rajasthan border.

The National Sample Survey Organization’s and Household Consumption Expenditure Survey (2022-23)prompted researchers to estimate Poverty and Inequality trends, highlighting data comparability and measurement issues.
Present trends of Poverty and Inequality in Indian Society:
1. Poverty Declined:
Poverty ratios declined from 29.5% in 2011-12 to 10% in 2022-23 (1.77% points per year) based on the Rangarajan Committee’spoverty lines.
Poverty ratios declined from 21.9% in 2011-12 to 3% in 2022-23 (1.72% points per year) based on the Tendulkar Committee’s poverty lines. Earlier period estimates showed a decline from 37.2% in 2004-05 to 21.9% in 2011-12 (2.18 percentage points per year).
2. Inequality Declined :
Subramanian’s estimates indicate the Gini coefficientdeclined from 0.278 to 0.269 for rural areas and from 0.358 to 0.318 for urban areas between 2011-12 and 2022-23.
The Gini coefficient measures the inequality among the values of a frequency distribution, such as levels of income.
Bansal et al show similar trends: Gini coefficient for rural areas declined from 0.284 to 0.266, and for urban areas from 0.363 to 0.315 over the same period. (significant decline in urban inequality compared to rural areas between 2011-12 and 2022-23)
Back2Basics:
Lakdawala Committee (1993):
It disaggregated poverty lines into state-specific poverty lines.
Poverty lines: same as Alagh’s committee of 1979. (2400 kcal per capita per day for rural areas and 2100 kcal per capita per day in urban areas.)
Poverty lines were updated using the Consumer Price Index of Industrial Workers (CPI-IW) in urban areas and the Consumer Price Index of Agricultural Labour (CPI-AL)in rural areas rather than using National Accounts Statistics.
Estimates of poverty: 54.9% (All India)
Tendulkar Committee (2009):
Constituted: In 2005
Submitted report: 2009.
Recommendations:
Firstly, the incorporation of private expenditure on health and education while estimating poverty.
Secondly, to shift away from two separate poverty line baskets (PLBs) (for rural and Urban) towards a uniform all-India PLB.
Thirdly, to shift away from Uniform Reference Period (URP) based estimates towards Mixed Reference Period (MRP) based estimates.
Fourthly, A change in the price adjustment procedure to correct spatial (across regions) and temporal (across time) issues with price adjustment.
It concluded that India’s poverty line was Rs. 446.68 per capita per month in rural areas and Rs. 578.80 per capita per month in urban areas in 2004-05.
Estimates of poverty: 37.2 % (All India)
C. Rangarajan Committee (2014):
Constituted: 2012
Submitted report: 2014.
Used a method of calculating urban and rural poverty separately (similar to the Lakdawala committee).
Took into account both food and non-food itemsof expenditure.
Used the MMRP method instead of MRP.
Poverty was estimated on monthly expenditure of a family of five (and not individual as in case of the Tendulkar committee). All three, i.e., Calorie + protein + Fat intake values were taken into account to estimate poverty.
Estimates of poverty: 29.5%
Poverty lines: Rural- Rs. 32; Urban- Rs.47
Methods to Estimate Absolute Poverty by NSSO:
Poverty estimation in India is now carried out by NITI Aayog’s task force through the calculation of poverty line based on the data captured by the NSSO under the Ministry of Statistics and Programme Implementation (MOSPI). It uses the following 3 methods:
Uniform Recall (reference) Period (URP): Under URP, consumption data for all items are collected for a 30-day recall period. When URP is applied, the households are surveyed about their consumption in the last 30 days preceding the date of the survey.
Until 1993-94, the poverty line estimated by NSSO was based on URP.
Mixed Recall (reference) Period (MRP): MRP takes into account consumption expenditure for five non-food items (clothing, footwear, durable goods, education, and institutional medical expenses) for a 365-day recall period, and consumption data for the remaining items are collected for a 30-day recall period.
Modified mixed reference period (MMRP): The Rangarajan Committee in its 2014 report recommended MMRP as a more suitable method to measure poverty as compared to URP and MRP methods. The World Bank in 2015 also supported the idea of shifting from MRP to MMRP. Under MMRP there are 3 reference periods as follows:
The 365-dayrecall period is used for clothing, footwear, education, institutional medical care, and durable goods.
The 7-dayrecall period for edible oil, egg, fish and meat, vegetables, fruits, spices, beverages, refreshments, processed food, paan, tobacco and intoxicants and
The 30-day recall period for the remaining food items, fuel, and light, miscellaneous
good and services including non-institutional medical, rents, and taxes.
Measurement issues regarding Poverty Lines and Consumption Expenditure:
Shift Away from Calorie Norm-based Poverty Line: The Tendulkar Committee recognized the inadequacy of a calorie norm-based poverty line. Instead, the Tendulkar Committee indirectly utilized calorie norms by adopting the urban poverty line based on the Lakdawala Committee’s methodology, which included calorie norms.
Need for new Consumption Basket: The Rangarajan Group emphasized the need for a new consumption basket that addresses both adequate nourishment and essential non-food items, alongside behaviorally determined non-food expenditure.
Estimating this new poverty basket required a fresh approach rather than simply updating an old basket with new prices.
Incomplete Capture of Public Expenditure: Despite efforts to impute values for public expenditure items, the imputation process captured only a fraction of the total public expenditure on subsidized or free items.
Complexity in Poverty Measurement: There is no universally agreed-upon method for measuring poverty, leading to variability in estimates.
Constitutional provisions related to eliminating inequalities:
i. [Article 38 (2) ]: Obligation of the State ‘to endeavour to eliminate inequalities in status, facilities and opportunities’ amongst individuals and groups of people residing in different areas or engaged in different vocations. ii. [Article 46]: Obligation of State ‘to promote with special care’ the educational and economic interests of ‘the weaker sections of the people’ (besides Scheduled Castes and Scheduled Tribes).
Conclusion: Given the inadequacy of calorie norm-based poverty lines, as recognized by the Tendulkar Committee, there is a need to adopt more effective and real-time approaches that will consider evolving consumption patterns.

PYQ:
[2016] With reference to the cultural history of India, the memorising of chronicles, dynastic histories and epic tales was the profession of who among the following?
Once again, the Muslim population has become a point of discussion. Last month, PM Narendra Modi referred Muslims in India, suggesting they have a higher birth rate.
Trends of Muslim Population as per Data Point (NFHS-5 2019-21) published on April 23:
Population Trends: The Economic Advisory Council to the Prime Minister noted a Muslims in the total population increased by 43.15% between 1950 and 2015, the share of Hindus decreased by 7.82% between 1950 and 2015.
The fertility rate of Muslims was 2.36 in 2019-21, much closer to the replacement level. The fertility rate is the average number of children a woman is expected to have in her lifetime. A rate of 2.1 (the ‘replacement level’) means that the population is stable.
Factors behind the High Population Growth of Muslims:
Socio-economic Factors: Socio-economic factors, rather than religion, significantly influence fertility rates. Educating girls, delaying marriage, promoting family planning awareness, and ensuring access to family planning measures are crucial in reducing fertility levels.
Regional Variations: Fertility rates among Muslim women vary regionally, influenced by the social and economic development of states.
Early Marriage and Literacy: There’s a positive correlation between higher fertility rates and early marriage among women aged 20-24. Conversely, a negative correlation exists between literacy rates among women and fertility rates.
Lack of Awareness: Lack of awareness about family planning remains a concern, with a significant portion of women reporting never hearing or seeing family planning messages.
Unmet Demand for Family Planning: Many women, particularly Muslims in certain states, have an unmet demand for family planning due to various factors, including lack of access to contraceptive measures.
Government Intervention: Increasing awareness about contraceptives, improving access to family planning measures, educating girls, and preventing child marriages are essential government functions to reduce fertility rates across religious groups.
Need for Coercive Measures:
Comprehensive Education and Awareness Programs: Implement educational campaigns that promote family planning, gender equality, and reproductive health awareness, targeting both men and women in communities across the country.
Access to Family Planning Services: Ensure easy access to a wide range of family planning methods and contraceptives, including in remote and underserved areas, through government health facilities and community outreach programs.

Mentor comment: The recent report ‘Share of Religious Minorities: A Cross-Country Analysis (1950-2015)’ conducted by the Economic Advisory Council analyzes the demographic changes in the religious composition of Indian Society as well as across 167 countries from 1950 to 2015. It focuses on the shifting shares of majority and minority religious groups, highlighting trends such as the decline in the Hindu population and the growth of the Muslim population in India. The study emphasizes the importance of understanding these changes as indicators of relative well-being within a country. We need to study this analysis as it is based on the premise that any change in minority populations is influenced by policies related to defining and treating minorities in our country.
Let’s learn
_
Why in the News?
The recent working paper titled ‘Share of Religious Minorities: A Cross-Country Analysis (1950-2015)’ by the Economic Advisory Council to the Prime Minister (EAC-PM), has major observations on Indian religious demographics.
Key highlights made by EAC-PM Report:
The paper is based on the baseline year as 1950, because this was the time around when the International Human Rights Framework was introduced under the aegis of the newly created United Nations. Considering the global trends of declining majority, India too has witnessed a reduction in the share of the majority religious denomination by 7.82%. According to the Report, the Hindu population decreased by 7.82% (1950-2015), while that of Muslims increased by 43.15%, suggesting a conducive environment in the country to foster diversity. The share of the Christian population rose from 2.24% to 2.36% — an increase of 5.38% between 1950 and 2015. While the share of the Sikh population increased from 1.24% in 1950 to 1.85% in 2015 — a 6.58% rise in their share, the share of the Parsi population in India witnessed a stark 85% decline, reducing from 0.03% share in 1950 to 0.004% in 2015.
South Asian Trends:
Within the neighborhood, the share of the majority religious denomination has increased and minority populations have shrunk alarmingly across countries like Bangladesh, Pakistan, Sri Lanka, Bhutan, and Afghanistan. Minority populations from across the neighborhood come to India during times of duress.
The present controversy over the EAC-PM Report:
The PM-EAC report on religious minorities in India has sparked debate due to its timing, outdated data, and selective focus.
For example, firstly, it does not highlight the nearly 1,520% increase in share in the total population of Buddhists, for every one Muslim, five Hindus were born during this period.
Secondly, the Hindu population has tripled, and the Total Fertility Rate (TFR) of Muslim women saw a drop of 2.05 against Hindu women’s TFR by 1.36, making it controversial.
Despite concerns raised by some, the demographers do not see that the Hindus are losing their majority status, given the historical context and current demographic patterns.
For example, when Hindus could retain their majority status during the 800 years of so-called Mughal rule, they cannot be in danger today.
Present rhetoric and challenges:
Need to have a broader outlook: Focusing solely on Total Fertility Rates to assess a group’s status overlooks broader factors like education and socioeconomic conditions.
Need to survey Public Participation: The representation of a particular religious group in the state’s power structure is a crucial indicator of its well-being.
The Finance Minister recently highlighted the growth of the Muslim population as a positive sign, emphasizing that Indian Muslims enjoy more rights compared to minorities in some Muslim-majority countries.
India is set to become the country with the largest Hindu and Muslim populations by 2050, showcasing the diversity and coexistence within the nation.
What does the Population Data say?
Stabilizing of the Minorities: The data on the decline in Muslim women’s fertility rates, as seen in Census data, indicates a positive trend toward stabilization. (according to the United Nations Population Fund)
Demographers predict that by the end of the century, Muslims may constitute around 18.8% of India’s population, with Hindus maintaining a significant majority at 74.7%.
Regional Variations: Various states have already achieved fertility rates below replacement levels, signaling a broader trend of population stabilization.
Whilethe Population Regulation Bill in 2019or the Population (Control) Bill in 2021has been introduced, some demographers generally emphasize the importance of addressing population dynamics through education, healthcare, and socioeconomic development.
Lack of Data-evidences: Claims of alarming Muslim population growth in certain regions like Assam lack substantial evidence, with data showing different growth patterns across states.
Illegal Muslim infiltration from Bangladesh is generally said to be responsible for the demographic change since the 1970s in Assam.
Are Coercive Methods Counter-productive?
International Norms and the Indian Government stance: Being a signatory to international covenants such as the International Covenant on Civil and Political Rights (ICCPR), India has to abide by the international norms on population control.
The United Nations Human Rights Committee has categorically mandated that state parties to ICCPR cannot adopt policies that are compulsory, coercive, or discriminatory.
Even the National Population Policy, of 2000 focused on more relevant socio-cultural factors such as age at marriage, age at birth, girl education, maternal and child health, and voluntary and informed consent over coercive methods.
Conclusion: To address concerns about population growth, efforts should concentrate on improving education and economic opportunities for all communities, including Muslims, rather than resorting to coercive measures.
In a rare event, the night sky over Hanle village in Ladakh was illuminated by the northern lights or aurora borealis.
Concurrently, the southern lights, or aurora australis, were observed in New Zealand and Australia.
What are Auroras?
Auroras are natural light displays that appear as bright, swirling curtains in the night sky.
They are typically seen near the Poles but can occasionally be observed at lower latitudes.
These lights can display a range of colors, including blue, red, yellow, green, and orange, due to the interaction of solar particles with different gases in the Earth’s atmosphere.
The phenomenon is known as:
Aurora borealis in Northern Hemisphere and
Aurora australis in Southern Hemisphere
What causes Auroras?
Interaction with Earth’s Magnetic Field: As the solar wind approaches Earth, it interacts with the planet’s magnetic field, causing some charged particles to enter the atmosphere near the poles.
Interaction with Gases: These particles interact with gases in the upper atmosphere, producing colourful flashes of light. Collision with oxygen produces green light, while interaction with nitrogen results in shades of blue and purple.
Reasons for Aurora in Ladakh:
Intense Solar Activity: Auroras can extend to lower latitudes during periods of intense solar activity, such as solar flares and coronal mass ejections (CMEs).
The CMEs are from the AR13664 region of the sun that has produced several high-energy solar flares
Localized magnetic anomalies: Variations in Earth’s magnetic field could potentially influence the occurrence of auroras in specific areas, including regions at lower latitudes.
Impact on Tech Infrastructure
Auroras can pose challenges to space-dependent technologies and operations.
Disruptions in Global Positioning Systems (GPS), radio communications, flight operations, power grids, and space exploration endeavors may occur during such events.
PYQ:
[2022] If a major solar storm (solar flare) reaches the Earth, which of the following are the possible effects on the Earth?

There’s a big argument between political parties about reservation. The BJP said some exaggerated things about the Congress wanting a caste census, suggesting it’s connected to religion.
Current debates on Reservation and Sub-categorization:
Constitutional Provisions: The Constituent Assembly opposed reservation solely based on religion, and the Constitution guarantees prohibition of discrimination based on religion under Articles 15 and 16.
History of Sub-categorization in Karnataka: In Karnataka, all Muslim communities are included within the OBC quota, forming the basis for the BJP’s current campaign.
Sub-categorization for Muslims within the OBC quota has existed in Karnataka since 1995.
The H. D. Deve Gowda-led government introduced it but was later removed by the Basavaraj Bommai-led government. However, the status quo continues after court observation.
Reservation for Muslim and Christian Communities: Socially and educationally backward Muslim and Christian communities are provided reservations under the OBC/MBC category in various states, including Karnataka, Kerala, Tamil Nadu, and Andhra Pradesh.
Constitutional Language and SC/ST Communities: The Constitution specifies that for SCs, the person should profess Hinduism, Sikhism, or Buddhism, but no such requirement exists for STs.
Congress Manifesto Promise: The Congress has promised in its manifesto to work towards removing the 50% cap placed on reservations, suggesting a potential shift in reservation policy if they come into power.
Affirmative action as per Constitution:
Constitutional Provisions: Articles 15 and 16 of the Constitution ensure equality to all citizens in actions by the state, including admissions to educational institutions and public employment.
They also enable the state to make special provisions for advancing socially and educationally backward classes, including OBC, SC, and ST.
Classification of Backward Classes: OBC is a collective term for socially and educationally backward castes, with some states also classifying certain castes as Most Backward Classes (MBC). Reservation percentages vary from state to state.
Indra Sawhney Case (1992): Supreme Court upheld 27% reservation for OBC. Caste is considered a determinant of class in the Indian context, and backwardness cannot be determined solely on economic criteria.
A cap of 50% was fixed for reservations unless there were exceptional circumstances.
Total reservation stood at 49.5% for OBC (27%), SC (15%), and ST (7.5%)—creamy layer exclusion from OBC reservation, with an income limit currently at ₹8 lakhs per annum.
Exclusion of children of certain government officials from the reservation.
Janhit Abhiyan Case (2022): The court upheld the constitutional validity of the reservation for Economically Weaker Sections (EWS). Economic criteria could be a reservation basis, according to the court’s majority opinion.
Affirmative Actions Globally:
In the U.S., there is ‘affirmative action’ that consists of government-approved and voluntary private programs granting special consideration to racial minorities like African Americans and Latin Americans.
In Fair Admissions vs Harvard case (2023), the U.S. Supreme Court, however, ruled that race-based affirmative action programs in college admissions violate the equal protection clause of the U.S. Constitution.
In the U.K., the law enables voluntary ‘positive action’ which allows employers to combat the under-representation of disadvantaged groups.
France does not have any affirmative action based on race or ethnicity. It provides educational measures designed to increase opportunities for low-income students.
Way Forward:
Need for Sub-categorization: The Rohini Commission was set up to provide recommendations on sub-categorization among OBC castes, as a significant portion of reserved jobs and seats have been garnered by a small percentage of OBC castes/sub-castes. Similar issues of concentration of benefits persist in the SC and ST categories.
Inclusion of Dalit Christians and Muslims: Dalit Christians and Muslims also suffer from discrimination and lack of opportunities. There is a need to extend reservation benefits to these communities and address their marginalization.

Australian weather agencies predict the possible return of a positive Indian Ocean Dipole (IOD) in the latter half of 2024.
What is the Indian Ocean Dipole (IOD)?
The IOD is also known as the Indian Nino. It is characterized by the differential heating of ocean waters in the eastern and western parts of the basin.
Similar to the El Nino Southern Oscillation (ENSO) in the Pacific, the IOD involves phases of ocean temperatures and atmospheric conditions that affect weather patterns across the region and beyond.
There are two main phases of the IOD:
Positive Phase: In this phase, the western Indian Ocean becomes warmer than average, and the eastern part cooler than average. This results in greater convection and rainfall over the western Indian Ocean and adjacent land areas like East Africa, while reducing rainfall over the eastern Indian Ocean and places like Indonesia and Australia.
Negative Phase: The opposite conditions prevail during this phase, with cooler waters in the western Indian Ocean and warmer waters in the east. This leads to increased rainfall in the eastern Indian Ocean regions and drier conditions in the western part and East Africa.
Back2Basics: El Nino-Southern Oscillation (ENSO)
El Nino and La Nina are two opposite phases of the El Nino-Southern Oscillation (ENSO) cycle.
ENSO is a naturally occurring phenomenon that involves the interaction between the ocean and atmosphere in the equatorial Pacific.

Impact on the Indian Monsoon:
The Indian Ocean Dipole has significant impacts on the Indian monsoon system:
Positive IOD often coincides with a stronger Southwest Monsoon, bringing more rainfall to India. This is due to the shift in warm water and accompanying convection towards India, which enhances the monsoon rainfall.
Negative IOD can weaken the Southwest Monsoon, resulting in less rainfall and potential drought conditions in India. The shift of warm water away from India reduces the necessary heat and moisture that drive the monsoon rains.
PYQ:
[2017] With reference to ‘Indian Ocean Dipole (IOD)’ sometimes mentioned in the news while forecasting Indian monsoon, which of the following statements is/are correct?
1. IOD phenomenon is characterised by a difference in sea surface temperature between tropical Western Indian Ocean and tropical Eastern Pacific Ocean.
2. An IOD phenomenon can influence an El Nino’s impact on the monsoon.

The Eta Aquariid meteor shower, an annual event, will reach its peak on May 5 and 6.
This meteor shower is a result of Earth intersecting with the debris trail left by Halley’s Comet during its orbit.
Halley’s Comet
Halley’s Comet is a short-period comet visible from Earth every 75–79 years.
It was last seen in Earth’s skies in 1986 and was met in space by an international fleet of spacecraft. It will return in 2061 on its regular journey around the Sun.
What are Meteoric Showers?
Meteors, fragments of dust, rock and ice, are expelled from comets during their celestial orbits around the sun.
The Earth’s atmosphere heats these space rocks as they descend, leaving luminous streaks of gas in their way.
NASA’s records confirms existence of over 30 meteor showers annually.
Origin of Meteor Showers:
Meteor showers originate from comets, remnants of the solar system’s formation composed of dust, rock, and ice.
Comets orbit the Sun in highly elliptical paths, and as they approach, they heat up, releasing gases and dust to form a glowing head and a tail stretching millions of miles.
When Earth traverses through the debris left behind by comets along their orbital plane, we witness meteor showers.
About Eta Aquariids
Known for their rapid speed, Eta Aquariid meteors produce long, glowing tails lasting several minutes.
Observers in the SouthernHemisphere can witness approximately 30 to 40 meteors per hour during the peak, while those in the Northern Hemisphere may see around 10 meteors per hour.
They seem to originate from the Aquarius constellation, hence the name ‘Eta Aquariid.’
