Mother & Child Health

This article deals with ‘Mother & Child Health – for UPSC.’ This is part of our series on ‘Society’, which is an important pillar of the GS-1 syllabus. For more articles, you can click here.

Why government should invest in Mother and Child Health?

Question: Imagine government as an investor. Given fiscal and capacity constraints, where would it invest to reap maximum benefits?

According to the Economic Survey, low-cost maternal and early-life health and nutrition programs offer very high returns because:

Spending on a mother is an economical option as a healthy mother is more likely to give birth to a healthy baby who learns better and stays in school longer. Additionally, a newborn’s most rapid physical and cognitive development occurs in the womb.
The success of subsequent interventions—schooling and training—is influenced by early-life development. E.g. Government’s investment in skills training can reap the best results only if Child has developed full Cognitive & Physical Health at an early age.

Important Indicators

Neo-Natal Mortality Rate

It is the number of deaths of children below the age of 1 month per 1000 live births.
According to NFHS-5 (2019-2021), India’s Neo Natal Mortality Rate is 24.9

NFHS-5 (2019-2021)	24.9
NFHS-4 (2015-2016)	29.5

Neo-Natal Mortality depends upon Mother’s health, as the leading cause of Mortality during the first month differs from the next 11 months. It depends on Utero Nutrition which is determined by the Birth-Weight of Children.
India has high Neo-Natal Mortality because Indian women begin pregnancy at low weight. Along with that, they don’t gain weight during pregnancy, resulting in low birth weight of the child.

Infant Mortality Rate (IMR)

Number of deaths of children below the age of 1 year per 1000 live births.
According to NFHS-5 (2019-2021), India’s Infant Mortality Rate is 35.2.

NFHS-5 (2019-2021)	35.2
NFHS-4 (2015-2016)	40.7

Note: IMR is an important indicator for determining the socio-economic status of any country because, more than any age group, the survival of infants depends upon their socio-economic environment.

Child Mortality Rate (CMR)

CMR is the number of deaths of children in the age group of 0-4 years per 1000 live births.

Under Five Mortality Rate (U5MR)

Number of deaths of children in the age group of 0-5 years per 1000 live births.
According to NFHS-5 (2019-2021), India’s U5MR is 41.9.

NFHS-5 (2019-2021)	41.9
NFHS-4 (2015-2016)	49.7

U5MR is an internationally accepted standard instead of Child Mortality Rate. Hence, India is moving towards it.

Maternal Mortality Rate (MMR)

The Maternal Mortality Rate is the death of mothers during or within 42 days of childbirth per 1 lakh live births.
According to NFHS-5 (2019-2021), India’s MMR is 97.

NFHS-5 (2019-2021)	97
NFHS-4 (2015-2016)	130

Schemes of Government to reduce MMR , IMR , CMR

Healthcare Data

Healthcare Expenditure

Global Burden of Disease Report (2018) by LANCET

Other Relevant Data

Doctor-Population Ratio	1:834 (against the WHO norm of 1:1000)
Number of Hospital Beds per 1000	0.7 (against the WHO norm of 3.5)

Political & Constitutional Angle

Health is under the State List. But there is debate regarding whether it should be moved to the Concurrent List, given that even after 70 years of independence, the state of Health in India is still poor. The Centre can only make model laws to which states can voluntarily subscribe.
Article 47 of the Indian Constitution (Directive Principle of State Policy) speaks about raising its people’s nutrition levels and living standards and improving public health as among its primary duties.
Article 21, i.e. Right to Life is Fundamental Right under the Indian Constitution.

Health and SDG

Sustainable Development Goals also talks about Health and SDG-3 aims to ensure healthy lives and promote well being for all at all ages.

Primary, Secondary and Tertiary Healthcare

Primary Healthcare

Primary Healthcare is the first level of contact between people & health system
It includes family planning, immunization, treatment of common diseases, health education etc.
In India, it is provided through a network of
- Primary Health Centres in Rural Areas
- Family Welfare Centres in Urban Areas

Secondary Healthcare

Secondary Healthcare denotes the second Tier of the health system.
It includes
- District Hospitals
- Community Health Centre (CHC) at Block Level

Tertiary Healthcare

Tertiary Healthcare denotes the third tier of the health system.
It provides specialized consultative care.
Tertiary Healthcare is provided through Medical Colleges & Medical Research Institutes.

Rural Healthcare System

State of Health Services in India

Health services in India need a booster shot, vouched by the following data.

Prominence of Private Sector: According to Economic Survey, out of 4% of expenditure on Healthcare in India, Public Sector accounts for just 1.15%
High Out-of-Pocket Expenditure (OoPE): The OoPE in India is as high as 62% compared to the world average of 18%. High OoPE pushes 39 million people every year under the poverty line.
Indian Doctors are not willing to serve in Rural Areas due to various factors, such as a lack of adequate healthcare infrastructure and low opportunity for professional growth.
The dominance of the Medical Council of India has hindered the development of nurses and other health cadres.
Hesitancy/Ignorance of common people: Even after a person has TB symptoms, they delay visiting a doctor (for a minimum of 5.2 months, even in Delhi). As a result, their disease becomes worse, and they infect more people.

With the implementation of the Ayushman Bharat program, the strengthening of SCs and PHCs is being done by converting them into Health and Wellness Centres (HWCs) in a phased manner to deliver comprehensive Primary Healthcare services through these Centres.

Health Schemes

Sub-National (1 Disease)	12. Japanese Encephalitis

5. Menstruation Health

Government is running following schemes for Menstruation Health.

Menstrual Hygiene for Adolescent Girls Scheme: To address the need for menstrual hygiene among adolescent girls residing in rural areas.
Project Stree Swabhiman (by Ministry of Electronics and Information Technology)
Menstrual Hygiene Scheme (by Health Ministry as part of Rashtriya Kishor Swasthya Karyakram. )
Rashtriya Madhyamik Shiksha Abhiyan (by Ministry of Human Resource Development)

6. Drug Price Control Order

The Drug Price Control Order (DPCO) of India is a regulatory framework established by the government to control and regulate the prices of essential medicines in the country.
Schedule 1 of DPCO contains the List of Essential Medicines. Their price can’t be more than the ceiling price.

Public Health Policy, 2017

The previous policy was formulated in 2002. There was a need for a new policy because

15 years have passed, and new challenges have come up in the health sector.
At that time, Polio was a major problem. Now, WHO has declared India to be Polio Free.
That policy was keeping in view of Millennium Development Goals (MDG). Now, we are in the era of Sustainable Development Goals (SDG).
At that time, Communicable Diseases were a major problem. Now Non-Communicable Diseases have come into the scene.

Provisions of the National Health Policy, 2017

1. Finance

Presently, the government spends 1.15 % of GDP on healthcare. The target is to increase that to 2.5% of GDP by 2025.

2. Targets to be achieved

Increase the life expectancy from 67.5 to 70 by 2025.
Reduce premature mortality from Non-Communicable Diseases by 25 per cent by 2025.
Achieve the global 2020 HIV target (also termed 90:90:90)

3. Preventive and Curative Care

The policy will rely on Preventive as well as Curative Health Care (the 2002 Policy relied just on curative )

4. Focus on Primary Care

Policy advocates allocating two-thirds (or more) of resources to primary care.

5. Promote AYUSH

AYUSH will be promoted

6. Promote Make in India

Promote drugs and devices manufactured in the country.

Criticism

The policy has abandoned the idea of making health a right proposed under the Draft Health Policy. NHP (2017) speaks of an “assurance-based approach”.
Raising Government Expenditure to 2.5% of GDP till 2025 is too far-fetched given problem India is facing is serious. Along with that, no year wise plan of yearly incrementation is given. There is lesser hope that even this will be attained given the past experience that the health policy of 2002 had promised health expenditure of 2% of its GDP on Health by 2010
Governance issues are ignored: The policy is silent on whether health should be moved to the Concurrent list.
Professional issues are ignored, e.g., MCI issues and private practice by Govt doctors.

Basics of Radioactivity

This article deals with ‘Basics of Radioactivity .’ This is part of our series on ‘Science and Technology’ which is an important pillar of the GS-3 syllabus. For more articles, you can click here.

Constituents of Atom

Atom has the following three constituents

Particle	Mass (Kg)	Charge (Coulomb)
Proton	1.672 X 10^-27	+ 1.6 X 10^ -19
Neutron	1.675 X 10^-27	Neutral
Electron	9.108 X 10^-31	1.6 X 10^-19

Mass of Proton almost = Mass of Neutron = 1830 X Mass of Electron.

Atomic Structure

In an atom, Central Nucleus is surrounded by electrons at various energy levels.
The most successful model is Wave Mechanical Model, but that is a mathematical rather than a visual model.
For our purpose, Bohr Atomic Model is enough.

Bohr Atomic Model

Atom consists of
- Central Nucleus: Containing all Protons & Neutrons with almost the whole mass concentrated here.
- Electrons: Revolves around the nucleus in a circular pattern (like planets around the sun)
Electrons can revolve only in certain specified orbits, with the electron in the innermost orbit having the smallest energy and the electron in the outermost orbit having the largest energy.
When an atom is provided energy either by strong heating or by bombardment with some fast-moving particle, Electrons in a natural state can jump to higher energy levels. But the atom doesn’t remain in that state for more than 10^-8 s & comes back to a normal lower energy level, emitting surplus energy in the form of Photons.
Emitted energy can be Visible, UV or X-Ray, depending on the energy difference.

Radioactivity

The property under which a heavy nucleus of an element disintegrates itself into smaller nuclei along with alpha, beta & gamma rays without being forced by any external agent to do so is termed radioactivity.
The phenomenon of radioactivity is natural and can’t be stopped.
It is found that all atoms with more than 83 protons; and a neutron-to-proton ratio of more than 1 as they are unstable. To achieve stability, unstable nuclei disintegrate spontaneously with the Alpha, Beta & Gamma Rays emission.
Henry Becquerel discovered the phenomenon of radioactivity.

Reason of Radioactivity

Inside the nucleus, positively charged Protons & Neutral are present. Hence, if only Electrostatic Force is there, all nuclei must have split apart due to repulsive forces. But this is not the case & the nucleus is stable.
But another force called Nuclear Force is working here. IT IS ATTRACTIVE FORCE EXISTING BETWEEN PROTON & PROTON and PROTON & NEUTRON. BUT THIS FORCE ACTS AT A VERY SMALL DISTANCE. Generally, Nuclear Forces overpower Electrostatic Forces inside the nucleus.
But in the case of larger nuclei, nuclear forces cannot overpower electrostatic forces, and they exhibit radioactivity.

Alpha, Beta & Gamma Radiations

The most common types are

	Alpha	Beta	Gamma
	Similar to Helium Nuclei (He (2,4)) and generally emitted by a large nucleus	These are fast energy electrons	– Gamma Radiations are electromagnetic radiations of high frequency – Generally emitted by unstable atoms to become stable by releasing energy
Penetration	It can penetrate 5 cm of air only.	It can penetrate air and paper.	It can penetrate most things except a thick sheet of lead or a very thick concrete wall.
Mass	Heaviest (4 amu)	Lighter (9.1 X 10^-31 kg)	Massless
Speed	Around 1/100 of the speed of light	33% to 99% of the speed of light	Equal to the speed of light
Ionising power	Maximum due to maximum charge (+2) and maximum mass	Intermediate between beta & gamma	Minimum due to zero charge
Effect on Photographic plate	Produce smaller effect	More effect	Maximum effect
Effect of Electric and magnetic field	Show deflection	Show deflection	Don’t show any deflection
Effect on the human body	It causes a burning effect	It can cause a shock on longer exposure	It can cause cancer

Transmutation

Transmutation is the process of altering one element to another.
Reason = Natural Radioactivity, Artificial Transmutation etc.
Artificial Transmutation is used to obtain elements with Atomic numbers greater than 92.

Half Age

It measures the time it takes for a given amount of the radioactive substance to become reduced to half due to decay and, therefore, the emission of radiation.

Carbon Dating

The technique of estimating the age of the remains of a once-living organism, such as a plant or animal
It involves measuring the radioactivity of its C-14 Content (the half-life of C-14 is 5570 years).
The ratio of C-14 / C-12 in nature is 1/106.

Uranium Dating

Uranium Dating is used for dating older but non-living things like rocks.
The age of rocks from the moon has been estimated to be 4.6 X 10^9 years, nearly the time of Earth’s origin.

Isotope, Isobars & Isoneutrons

Atomic Number (Z) = Number of Protons
Mass Number (A) = Number of Neutrons & Protons

Isotope

Isotopes are nuclides with same Atomic Numbers but different Mass Numbers.
E.g., U (92,235) & U (92,238 ) + C-12 & C-14
Generally, isotopes don’t have different names except for isotopes of Hydrogen named Protium (H(1,1), Deuterium (H (1,2)) & Tritium (H(1,3)).

Isobars

Isobars are nuclides having same Mass Number but different Atomic Numbers.
E.g., K (19,40) & Ca (20,40) + C (6,14) & N (7,14)
They have different names.

Isoneutrons

Isoneutrons are nuclides having the same number of neutrons.
Examples include
1. C (6,14) & O(8,16): Both have 8 neutrons
2. H (1,3) & He (2,4): Both have 2 neutrons

Nuclear Fission Reactors

This article deals with ‘Nuclear Fission Reactors .’ This is part of our series on ‘Science and Technology’ which is important pillar of GS-3 syllabus . For more articles , you can click here.

Nuclear Fission

In 1939, Otto Hahn and Strassman discovered Nuclear Fission when they found that a slow-moving neutron collides with a uranium nucleus; it breaks into two smaller nuclei of comparable masses with the release of energy.
In simple words, Nuclear Fission means breaking up the heavier nucleus into two smaller nuclei and releasing an enormous amount of energy.

Reactant total mass is more than product total mass & EXCESS mass is converted to energy (using Einstein’s Mass – Energy Relation (E = mc^2)). The energy released from 1 nucleus of Uranium (235) is nearly 93 Mega Electron Volt. When one Uranium nucleus undergoes fission, the energy released might be small. But from each fission reaction, three neutrons are released. These three neutrons can cause further fission in three other Uranium nuclei. This process is called a chain reaction.
The energy produced in the nuclear reaction can be used to convert water into steam, which can be converted into electricity using Steam Turbine and Generator.

Types of Reactors

A simple Nuclear Reactor from which electricity can be generated is of following type

Fuel	U-235, U-233, Pu – 239 or Th -232 is used as fuel in the Nuclear Reactor
Moderator	– It reduces the speed of neutrons so that nuclear reactions can take place. – Graphite or Heavy Water (D2O) is used as Moderator.
Coolant	– The coolant absorbs the energy/heat released from the reaction and transfers it into turbines. – Heavy Water or Water can be used as coolant (depending on the type of Reactor)
Control Rods	– To control the speed of the Nuclear Reactor. – Boron or Cadmium is used as Control Rod.
Concrete Shield	Concrete wall with 2-5 m thickness to stop radiation from spreading.

Reactors used in India

1. Pressurized Heavy Water Reactor (PHWR)

Most of the Nuclear Reactors found in India are PHWRs.

Information at Glance

Fuel	Natural Uranium (without enrichment) (It is easier to make and less expensive to use, as Uranium enrichment is a complex process)
Coolant	Heavy Water/Deuterium Oxide
By Products	Plutonium (more amount )
Moderator	Heavy Water/Deuterium Oxide (Moderator and coolant are same) => Neutrons collide with Heavy Water molecules and slow them.
Why Pressurized	If water is heated, it expands & becomes less dense. As a result probability of collision between neutrons and water molecules to reduce the speed of neutrons decreases. It is crucial to decrease the speed of neutrons to ensure fission.
Cost	Less Expensive

Details of PHWRs

The primary reaction which leads to the generation of energy while using Uranium as fuel is

The most crucial point in Uranium Fission Reaction is the release of an extra 2.5 (average) Neutrons, which leads to the possibility of a chain reaction. If controlled, it can be used to produce energy called Nuclear Energy. At the same time, if it remains uncontrolled, it can result in an Atomic Bomb.
But the biggest hurdle, in this case, is the fact that neutrons liberated in the nuclear reaction are fast-moving & will not cause fission (instead, they will escape without causing any collision). To ensure a Fission reaction, these neutrons must be slowed. For this purpose, Moderators are used, which in this case are D2O (Heavy Water) & Graphite.
The reaction rate can be controlled by Control Rods, which are made up of neutron-absorbing material like Cadmium.
The energy released in fission is continuously removed by a suitable Coolant which transfers heat to a working fluid which in turn may produce steam to drive the turbine & generate electricity.
Pressuriser is used because when heavy water is heated, it expands & becomes less dense. As a result probability of collision between neutrons and heavy water molecules to reduce the speed of neutrons decreases. It is crucial to decrease the speed of neutrons to ensure fission. The Pressuriser ensures the suitable density of the heavy water.

2. Boiling Water Reactor (BWR)

It is the oldest type of Nuclear Reactor.
Fuel Used: Enriched Uranium
Working: Energy released during the fission reaction directly heats the (light) water. The same water is used to turn the turbine and then recycled back, to be used again in the cycle.
Moderator: No Moderator is used. The probability of neutron colliding with U-235 is achieved by using Enriched Uranium.

BWRs are the second most widely used reactors in the world. But in India, we don’t use them on a large scale. Tarapur Atomic Power Station was constructed initially with two boiling water reactors (BWR) under the 1963 Agreement between India, USA & International Atomic Energy Agency (IAEA).

Issue with BWR

The use of enriched Uranium increases cost and complexities.
Light water is directly heated by radioactive material. Hence, nuclear radiation fallout in case of an accident is maximum in such reactors. For example, Japan’s Fukushima Nuclear reactor, which caused great damage after a nuclear accident, was BWR.

3. Fast Breeder Reactor

Fast Breeder Reactor produces the same kind of fissile material as it burns.
While using Pu239 as fuel, it can produce more Pu239 than it consumes by converting non-fissionable U-238 present in the natural Uranium.
With fast neutrons, the chances of absorption by U-238 increase. Additionally, Pu-239 produces extra neutrons in the case of a collision with fast-moving neutrons only. Hence, these reactors don’t use moderators to slow down the neutrons.
Liquid sodium or steam coolants are used in FBRs.
India’s BHAVINI nuclear reactor is Prototype Fast Breeder Reactor.

Indian Three Stage Nuclear Program

Indian Three Stage Nuclear Program

This article deals with ‘Indian Three Stage Nuclear Program.’ This is part of our series on ‘Science and Technology’ which is an important pillar of the GS-3 syllabus. For more articles, you can click here

Introduction

Homi Bhabha formulated India’s 3-Stage Nuclear Program.
The reason for the formulation of this program was that India has the largest source of Thorium and modest deposits of Uranium. Considering this fact, Dr Homi Bhabha envisioned 3-Stage Nuclear Program in 1954. It aimed to secure India’s long-term energy independence by using Uranium and Thorium reserves found in the Monazite sands of coastal India.
Note: India has only 1-2% of the global Uranium but about 30% of the world’s Thorium.

Stage 1

The first stage involves the utilization of Pressurized Heavy Water Reactors (PHWR) fuelled by natural Uranium. In this stage, natural Uranium is used as a fuel, and heavy water (deuterium oxide) is used as a moderator and coolant. India has built several PHWRs, which generate electricity and produce plutonium-239 as a by-product (to be used as fuel for the next stage.)

Overview

Reactor

Pressurized Heavy Water Reactor (PHWR)

Fuel used

Natural Uranium (Note: It is not enriched. Just Natural Uranium is used.)

Moderator and coolant

Heavy Water (D2O/Deuterium Oxide)

Reaction

Main Reaction (Energy)

Other (to get Pu -239)

Process explained

Natural Uranium contains both U-238 and U-235 in the following proportions.

In Nuclear Reactor, when a slow-moving Neutron is bombarded on the Uranium fuel, it collides with and splits U-235 nuclei, thus releasing a large amount of energy and 3 neutrons. The production of 3 neutrons helps in making it a chain reaction.
Some of the neutrons will get absorbed into U-238, thus converting it into Pu-238 (Plutonium-238, which is fissile). Pu-238, thus generated, acts as fuel in the second stage.

Pressurized Heavy Water Reactor

Why is Heavy Water is used as Moderator?

A moderator in the form of Heavy Water is used to decrease the speed of neutrons produced in the nuclear reaction because it increases the probability of fission with Uranium-235, even though its proportion is just 0.7% in natural Uranium.
Heavy water slows down neutrons by their repeated collisions with neutrons.

Control Rods

To reduce the power level or to shut down the reactor, the reaction rate is lowered by decreasing the number of available neutrons. It is achieved with the help of control rods like Boron or Cadmium Rods, which can absorb the neutrons.

The operator of PHWR or First Stage of the Indian Nuclear Program

PHWR is operated by NPCIL or Nuclear Power Corporation of India Limited.
Almost the entire base of Indian nuclear power is composed of stage 1 PHWRS except for the two Boiling Water Reactors (BWRs) at Tarapore.

Stage 2

Fast Breeder Reactor

Overview

The second stage focuses on utilizing Fast Breeder Reactors. FBRs use Plutonium-239 obtained from the spent fuel of PHWRs as the fuel and liquid sodium as the coolant. These reactors can generate more fissile material (Plutonium-239) than they consume. Thorium would be added to the fuel cycle once sufficient stock had been amassed to transform it into uranium 233 for the third stage.

Reactor

FBR (Fast Breeder Reactor )

Fuel used

Mixed oxide (MOX) fuel (received from first stage) consisting of

Pu-239	Undergo fission to produce more energy
U-238	Undergo change to additional Pu239

Moderator

FBR doesn’t use a Moderator, as only fast-moving neutrons produce extra neutrons on collision with Pu-239.

Coolant

Liquid Sodium

Crucialties of Stage 2

Further, 2nd stage is crucial for 3rd stage as it converts Thorium-232 (which occurs naturally) into Uranium–233 by transmutation

Once there is a good reserve of Pu-239, Th-232 is introduced at the periphery of the core (blanket material).
The collision with neutrons will convert Th-232 to U-233 (which is fissile).

Stage 3

Thorium Based Reactors

The program’s third and final stage involves deploying Advanced Heavy Water Reactors. AHWRs are designed to use a mix of Thorium-232 and Uranium-233 (obtained as a by-product from 2nd stage) as fuel. Additionally, The Th-232 will be placed at the periphery of the Core fuel, resulting in additional U-233 fuel.

It’s important to note that while India has made significant progress in the first two stages, the third stage of the program is still in the developmental phase, and commercial deployment of AHWRs is yet to take place.

Thorium as Nuclear Fuel

India & Thorium

India has the largest reserve of Thorium in the world and consists of 30% of the world’s Uranium reserves
Main Indian reserves include
- Monazite beach sand in Kerala
- Found in Andhra (largest producer), Tamil Nadu, Odisha, Kerala and West Bengal

Advantages

Thorium is more abundant (4 times more) than Uranium in the Earth’s crust.
Thorium consists of a single isotope, Th-232, unlike Uranium. Hence there is no need for the isotope separation.
Thorium-based fuels have favourable physical and Chemical properties that improve the reactor’s performance. These include
- Higher melting point
- Higher thermal conductivity
- Low coefficient of thermal expansion
- Greater chemical stability
- Doesn’t further oxidise
The long-term radiological hazard of Uranium based nuclear fuel, dominated by Plutonium and other Actinides is not there in Thorium based fuel.

Disadvantages

No fissile isotopes in natural Thorium
The high sintering temperature required to make Thorium Oxide
Long interval over which Thorium 232 breeds to Uranium 233

Ethical Governance in India

Last Updated: May 2023 (Ethical Governance in India)

Ethical Governance in India

This article deals with the topic titled ‘ Ethical Governance in India (UPSC Notes) .’ This is part of our series on ‘Ethics’. For more articles, you can click here.

Introduction

Ethical Governance is a corruption-free, moral and people-centric government.

Philosophical Basis of Ethical Governance

People think that concept of Good Governance is modern. But they are wrong. Many times in past, scholars have conceptualized what constitutes good governance.

Kautilya

Kautilya, in his Arthashastra, wrote, “In the happiness of subjects lies the happiness of king and in the welfare of subjects lies the welfare of king. ” Hence, he has written about Citizen-Centric Government.
Kautilya has also highlighted the corruption & given the concept of Kantakshodhana, i.e. king should purge those elements strictly.

Gandhi’s Vision of Ramrajya

The vision of Ramrajya, or the ideal state, involves Governance based on Moral Principles like nonviolence, truth, and righteousness.
Gandhi said that government which is not working in the people’s interest is morally corrupt.
Swaraj, i.e. Self Rule, is one of the pillars of his Ramrajya or Good Governance.

Aristotle

He has divided the government into two parts

Perverted Government: Power is used in the interest of the ruling class
Legitimate Government: Power is used in the public interest

8 Characters of Ethical Government

Rule of Law

Rule of Law involves governance based upon rules and regulations
In modern times, these rules & regulations are codified in the country’s constitution and laws.

People’s Participation

Real democracy doesn’t just mean voting to elect government but the participation of people in governance itself.
The mechanism of people’s participation in contemporary times are

Conventional Tools	– Voting – Pressure Groups
New & Contemporary	– Panchayati Raj Institutions & Gram Sabha – RTI – Social Auditing – Citizen Charter – e-Governance (C2G) – Social Media (change.org, online petitions)

Consensus Orientation

Consensus Orientation in governance involves seeking input from various individuals and groups affected by a decision or policy, aiming to reach a consensus that considers the diverse perspectives and interests involved.
Ethical Governance is opposite to the ‘Winner takes All’ approach.

Equity and Inclusiveness

The distribution of resources should be based on the principle of equity so that different sections of society receive these resources based on their need
Inclusiveness involves including weaker sections in decision-making.

Effective and Efficient

Effective government achieves the targets in the stipulated time.
An efficient government is one which delivers maximum with minimum resources

Impediments to Ethical Governance in India

The whole scene has to be seen in the context of

Corruption, Nepotism and Crony Capitalism
Misuse of power in personal interest
Red Tapism: Undue delay in public service delivery because of complex procedures
Lack of Transparency
Weak Accountability
Lack of public participation in decision making
Bureaucratic apathy, particularly towards weaker sections of society
Status quo and elitist orientation of bureaucracy
Politicization of Bureaucracy
Criminalization of politics

How to Strengthen Ethical Governance

For this, we need to take various steps in various fields

1. Political Structure

Enforce expenditure limits on elections strictly
Bring Political Parties under RTI
Remove excessive protection given to tainted politicians

2. Statutory Structure

2nd Administrative Reforms Commission (ARC) has given various recommendations in this regard

Amend the Prevention of Corruption Act
Integrity Pacts – When Government Organisation signs any contract with a Private organization, sign integrity pacts stating that if Private Organisation is found involved in any wrongdoing, the contract will cancel automatically.

3. Institutional Structure

Strengthen and give more teeth to CVC, Lokpal, CBI etc.

4. Social Infrastructure

Take help of society in reducing corruption and increasing Ethical Governance

Give Civic Education in Schools.
False Claims Act (USA): If you think there is wrongdoing in some organization, gather evidence & produce it before the court. If the fine is imposed on that organization, some portion of money from that fine will be given to the litigant.
Social Audit: Social Audit is the audit through client or beneficiary groups or civil society groups (i.e. stakeholders) to ensure the social accountability of an organization.

Fossil Fuel Resources in India

This article deals with ‘Fossil Fuel Resources in India.’ This is part of our series on ‘Geography’, which is an important pillar of the GS-1 syllabus. For more articles, you can click here.

Categories of Energy Sources

Conventional: Conventional energy sources refer to the traditional methods of generating power that has been widely used for many years—E.g., Coal, Petroleum etc.
Non-Conventional: Non-conventional sources of energy are energy resources that are not derived from traditional fossil fuels—E.g. Solar, Wind etc.

1. Coal

Types of Coal

1. Peat

It has the highest percentage of moisture & gives more smoke.
Carbon content is 40% (lowest).
It represents the very first stage of coal formation.

2. Lignite

It is also known as Brown Coal and is superior to Peat.
Under pressure & heat, with time, Peat converts to lignite.
Carbon content is 40-60%.
In India, it is found in Neyveli (Tamil Nadu) (largest deposit), Palana (Rajasthan), and Lakhimpur (Assam).

3. Bituminous

It is also known as Black Coal.
It is dense, compact & black in colour.
Carbon content is 60-80%.
Almost 80% of Indian Coal is Bituminous.
It is found in Jharkhand, Orissa, West Bengal & Madhya Pradesh.

4. Anthracite

It is known as Hard Coal.
When buried deep, all moisture gets expelled & Anthracite coal is formed.
Carbon content is 80-90%.
It has a short flame & is the most expensive of all.
In India, Anthracite coal is found only in Jammu and Kashmir (Kalakot).

Distribution of Coal in the World

1. China

China has the largest reserves in the world (12%).
Overwhelming concentrations are found around
- Hwang Ho river basin, particularly in Shansi
- Manchurian coal fields
- Shantung Hupei fields

2. USA

The USA has the second largest reserves in the world.
Main coal regions
- Appalachian Region
- Arkansas Rocky Region
- Illinois
- Indiana

3. Australia

Australia has the fourth largest coal reserves, but they are substantially unexploited.
Main regions
1. Queensland
2. Tasmania
3. New South Wales
4. Victoria

4. Russia

5. Ukraine

A substantial amount of coal reserves are found in Donetsk Basin.

6. Germany

Germany is the largest coal producer in mainland Europe.
Main coal regions
1. Ruhr Valley
2. Saxony
3. Saar Basin

7. South Africa

The main coal regions in South Africa include Transvaal, Cape Province, and New Castle.

Indian Coal

India has the third largest coal reserves in the world, but coal is of medium quality.
India coal was not formed in the Carboniferous period. (Hence, it is not Anthracite)
Most of the Indian Coal was formed in the Gondwana period. Hence, approx. 80% of Indian coal is Bituminous and non-coking grade.
Since Indian Coal is of non-coking grade, it can’t be used as a reducing agent in metallurgical processes. Hence, coking coal is imported
Indian coal has low sulphur but high moisture. Thus it produces more smoke.

Formation of Indian Coal

Coal formation spans millions of years, involving the accumulation and transformation of organic matter. Globally, the formation of coal can be traced back to Carboniferous Period. But in India, most of the coal is from the Gondwana period. Coal formation begins with the accumulation of plant material in swamps and marshes to form peat. As more layers of plant material accumulated, the weight of the overlying sediment and the pressure from the Earth’s crust compressed the peat, gradually transforming it into coal, in the process known as coalification.

In India, Coal occurs in the rock sequences of two geological ages, i.e. Gondwana and Tertiary deposits.

1. Gondwana Coal

It was formed 570-275 million years ago (due to in Damodar-Mahanadi Rift)
Most of the coal reserves in India consist of Gondwana coal.
Gondwana coal is of Bituminous type.

2. Tertiary Coal

Tertiary coal belongs to the Oligocene period (15 to 60 million years ago).
2% of coal reserves in India is of Tertiary coal
Tertiary coal has low carbon content, in the range of 40-60%.
The largest deposit of Tertiary coal is found in Neyveli in Tamil Nadu.

2. Lignite Coal

Tamil Nadu	Neyvelli
Rajasthan	Palana
Gujarat	Umarsar

3. Anthracite Coal

Only found in one place

Jammu and Kashmir

Kalakot

Problems of Indian Coal

India doesn’t has high-grade coking coal. Hence, India depends on imports to meet domestic requirements.
Regulatory challenges: A stricter regulatory framework for land acquisition, resettlement and rehabilitation, and environment management leads to a higher cost of compliance for access and extraction of coal.
Good & low-grade coal are found together in Indian mines. Mining companies do selective mining & extract good coal, leaving bad coal behind. Selective mining is wasteful.
India does open-cast mining—in contrast to underground mining worldwide. The open cast is cheaper but is associated with high pollution.
Deep mining techniques used in India are primitive, leading to high causalities.
Poor connectivity from coal mines to consumer locations via railways leads to a mismatch of demand and supply.
Mining is primarily done by PSUs (Coal India). Their efficiency is low.
The poor financial state of DISCOMs: This has led to a financial challenge in the overall power sector. Several states, including Jharkhand and Maharashtra, have large outstanding dues to coal companies.

2. Petroleum

Petroleum is obtained from sedimentary rocks of Marine origin of the Tertiary period.

Theory of Origin

The origin of Petroleum & Natural gas is considered to be organic. Marine Living Organisms (like fish and microscopic plants and animals) got buried under accumulated sediments of crude mud, silt & sand and underwent a chemical change to form crude oil and natural gas due to high pressure & heat after millions of years. It is the reason why oil is found in many seabed.
The point to note is that where ever oil is found on land, that region must have been undersea in the geological history because that is the only way living organisms can be settled there and then pressurized to form oil.
E.g. the Middle East has enormous oil reserves because of the same reason. From 500-100 million years ago (MYA), large portions of the modern-day Middle East were submerged under a large, now non-existent sea called the Tethys Sea. Rivers feeding this ancient ocean saturated it with nutrients, giving rise to massive numbers of microscopic animals. They died & fell to the bottom of the sea, which was pressurized to form oil.

Some History

The first oil well was constructed in the USA in 1859.
In India, Petroleum was first discovered at Margherita (upper Assam) in 1860 by Assam Railway & Trading Company & then in Digboi in 1869.
ONGC was established in 1956. Later, ONGC discovered oil in the Gulf of Khambat in 1961 & Bombay High in 1976.

3. Natural Gas

Sedimentary rocks in which hydrocarbons are trapped often hold gas, which may be in association with crude oil or alone.
It consists primarily of methane, which is lighter than air & toxic. It requires air-tight tanks for storage & similarly, leakproof pipes or trucks for transport, raising capital costs.

Global Distribution

Introduction

India is ranked 10th in terms of t tourism’s total contribution to GDP, contributing 4.7% to total GDP.
It is a labor-intensive sector, accounting for 39 million jobs (2020) and significantly impacts trade, investment, social inclusion, etc.
But India has not been able to exploit the potential of tourism to full capacity (corroborated by India vs. USA)

Hence, India has vast untapped potential in the tourism sector

Potential of Tourism in India

Large Diversity in Landscape: India’s landscape can cater to almost every type of traveller, whether they are seeking adventure, wellness, culture and heritage or cuisines.
Ancient Civilisation: India is an ancient civilization, and a number of historical places and buildings have tremendous potential to draw tourists. E.g., Hampi, Khajuraho, Agra, Delhi, Madurai etc.
Religious Tourism: India is home to a large number of religions. Hinduism, Sikhism and Buddhism took birth here.
Huge Labour Available: The availability of a huge labour force, both skilled and unskilled, can act as a catalyst.
Medical Tourism: India can provide specialized treatments at the cost of 1/4th that of developed countries. Target countries include Central Asia, Neighbours like Bangladesh, Sri Lanka etc.
MICE (Meeting, Incentive, Conferences & Exhibitions): It is a specialized niche of business tourism. Indian MICE Tourism potential is pegged at 25,000 crore due to Places like Pragati Maidan Delhi (for exhibition) and institutes like IITs, AIIMS, IIMs etc., for International Conferences.

Reasons for untapped Tourism Potential

The tourism industry is closely integrated with several other industries like the hotel industry, accommodation, aviation, railway, roadways, healthcare, entertainment etc. The combined weaknesses of all the sectors make Indian Tourism more vulnerable.
Negative perceptions, such as India being unsafe for female foreign tourists and lack of hygiene, negatively impact Indian tourism.
Governance Issue :
1. Government is unable to make schemes to attract tourists like Buddhist Tourists who have cultural ties with India.
2. No advertisement campaigns like Malaysian and Singapore Tourism are run in foreign countries.
3. Lack of automated immigration procedures like Visa on Arrival.
Limited professionalism in people involved in the tourism sector, like tourist guides
Insurgency in potential Tourist Spots: Tourist places like Kashmir and North East are hit by insurgency, impacting tourism potential.

Schemes to Promote Tourism in India

In the last two years, the Ministry of Tourism has taken many steps to make India an attractive destination.

PRASAD Scheme: To develop tourism infrastructure in and around famous religious and pilgrimage cities. (12 cities Ajmer, Amritsar, Amravati, Dwarka, Gaya, Kamakhaya, Kancheepuram, Kedarnath, Mathura, Patna, Puri, Varanasi and Velankanni)
HRIDAY: For holistic development of Heritage cities (12 identified Cities, namely, Ajmer, Amaravati, Amritsar, Badami, Dwarka, Gaya, Kanchipuram, Mathura, Puri, Varanasi, Velankanni and Warangal.)
Swadesh Darshan Scheme: It aims to develop a theme-based tourist circuit. These circuits include North-East India Circuit, Buddhist Circuit, Himalayan Circuit, Coastal Circuit, Krishna Circuit, Desert Circuit, Tribal Circuit, Eco Circuit, Wildlife Circuit, Rural Circuit, Spiritual Circuit, Ramayana Circuit and Heritage Circuit.
Adopt a Heritage: Corporate Houses will adopt a Heritage and develop their infrastructure. E.g., Dalmia Group adopted Red Fort for ₹ 25 Crore, and they will provide basic amenities and develop infrastructure.
E-visa process simplified: Nationals of 161 countries have been allowed visits for business and medical treatment. Additionally, a special visa category called ‘Medical Visa’ & ‘Medical Attendant Visa‘ has been created to ease the entry of medical tourists into India
The government is building a large number of museums to showcase Indian heritage and promote tourism.
Incredible India Tourist Helpline: Multilingual helpline has been launched to provide assistance and information to tourists in 12 languages of the world, including Hindi & English
100 % FDI allowed in hotels, resorts & recreational activities
Revamped schemes like Hunar se Ruzgar to give training to travel guides and Institutes of Hotel Management have been opened.
State Specific
- Rajasthan has passed a bill under which misbehaviour with tourists has been made a cognizable offence. It is to prevent the touts from forcing tourists to buy things at exorbitant prices or fraudulating the tourists, as it impacts tourism negatively.
