9.1. Production
Production means creation of value in the goods, i. e. creation of utility. Production activity helps in transforming a set of inputs into goods and services. It essentially means transforming of one set of goods into another. The output generated from production possesses greater utility than the combined inputs used in the production process. The inputs that are utilized in production of goods may be provided by the nature and/ or by other industries.
9.2. Factors of Production
These mean the production resources required to produce a given product. Fraser defined factor of production as “a group or class of original productive resources”. The factors of production have been traditionally classified as land, labour, capital and organization.
Land
According to Marshall, land means “the materials and forces which nature gives freely for man’s aid, in land and water, in air and light and heat.” In Economics the term land has a very broad meaning. It includes all free gifts of nature available to mankind viz., air, water and land. It includes all types of land surfaces such as mountains, valley, plains, forests etc. It includes all types of water resources such as rivers, oceans, etc. Thus the concept of land includes all natural resources on, above and below the earth’s surface.

8.1. Meaning
The Law of Demand states that when the price of a good increases, its quantity demanded decreases, assuming all other factors remain constant. However, the law does not specify how much the quantity demanded will decrease in response to a price increase or how sensitive demand is to price changes. This information is crucial for businesses and policymakers. To address this, Alfred Marshall developed the concept of elasticity of demand, which measures the responsiveness of quantity demanded to changes in factors such as price, income, and the price of related goods.
8.2. Type of Elasticity of Demand
There are three types of elasticity of demand viz., 01) Price Elasticity of Demand 02) Income Elasticity of Demand 03) Cross elasticity of Demand
1. Price elasticity of Demand
Price elasticity measures the responsiveness of the quantity demanded of a commodity to changes in its price, while keeping all other factors constant (ceteris paribus).

7.1. Introduction
The concept of consumer’s surplus was first introduced by Alfred Marshall. When a consumer plans to buy a commodity, they assess the utility they will gain from its consumption. A rational consumer always compares the utility derived from a good with the price they must pay for it. If the utility exceeds the price, the consumer chooses to buy it; otherwise, they do not. The excess utility gained over the price paid is known as consumer’s surplus.
In nutshell, Consumer’s surplus is the difference between the amount a
consumer is willing to pay for a good and the amount they actually pay.
Consumer’s surplus = Price that a consumer is willing to pay - Price he actual pays
Suppose a consumer wants to buy a shirt and is willing to pay `250 for it, but the actual price is only `200. In this case, the consumer gains a surplus of `50. This difference, known as consumer’s surplus, represents the extra benefit the consumer receives from the purchase.
Consumer’s surplus is often experienced with commodities that are highly useful but relatively inexpensive, such as newspapers, salt, matchboxes, and postage stamps. In these cases, consumers are willing to pay more than the actual price, resulting in a surplus of utility

6.1. Concept of Utility
In the ordinary language, ‘utility’ means ‘usefulness’. In Economics, utility is defined as the power of a commodity or a service to satisfy a human want. Utility is a subjective or psychological concept. The same commodity or service gives different utilities to different people. For a vegetarian, mutton has no utility. Warm clothes have little utility for the people in hot countries. So utility is determined by the consumer and his need for the commodity.
Total Utility
Total Utility is denoted by the sum of utilities of all units of a commodity consumed. For example, if a consumer consumes ten biscuits, then the total utility is the sum of satisfaction of consuming all the ten biscuits.
Marginal Utility
Marginal Utility is the addition made to the total utility by consuming one more unit of a commodity. For example, if a consumer consumes 10 biscuits, the marginal utility of 10th unit is nothing but the total utility of 10 biscuits minus the total utility of 9 biscuits.
6.2. Law Of Diminishing Marginal Utility
The law of diminishing marginal utility explains an ordinary experience of a consumer. If a consumer takes more units of a commodity, the additional utility he derives from an extra unit of the commodity goes on falling. Thus, according to this law, the marginal utility decreases with the increase in the consumption of a commodity. When marginal utility decreases, the total utility increases at a diminishing rate.

5.1. Meaning
Demand in economics means a desire to possess a good supported by willingness and ability to pay for it. If you have a desire to buy a tractor, but do not have the adequate means to pay for it, it will simply be a wish, a desire or a want and not demand. Demand is an effective desire, i.e., a desire which is backed by willingness and ability to pay for a commodity in order to obtain it. In the words, “Demand means the various quantities of a good that consumer willing and able to purchase at various price during a particular period of time in a given place/market”. Thus, demand in economics implies both the desire to purchase and the ability to pay for a good.
5.2. Definitions
1. According to Prof. J M Keynes, “emphasized the importance of effective demand, which is the total amount of goods and services that consumers are willing and able to purchase at various price levels, taking into account their income and other factors”.
2. According to Alfred Marshall, “the amount demanded of a commodity is the amount that buyers are able and willing to purchase at a given price in a given time period.”
3. According to John Maynard Keynes: “demand as the total amount of goods and services that individuals, businesses and the government are willing and able to purchase at various price levels”.
4. According to Milton Friedman “demand as the quantity of a good or service that people are willing to buy at a specific price, influenced by their utility and income”.
5. According to Paul Samuelson “demand as the quantity of a product that consumers are willing to buy at different prices, holding other factors constant”.

4.1. Introduction
The agricultural sector plays a vital role in a nation’s economic development. It has been a key driver of prosperity in advanced economies and remains essential for the progress of developing nations. In regions with low per capita real income, agriculture and other primary industries are given high priority. As Dr. Bright Singh emphasizes, “An increase in agricultural production, along with a rise in the per capita income of the rural population, fosters industrialization and urbanization, thereby boosting demand for industrial goods.”
The historical trajectory of England provides clear evidence that the Agricultural Revolution preceded and laid the foundation for the Industrial Revolution. Similarly, in the United States and Japan, agricultural advancement has played a pivotal role in fostering industrialization. Many developing nations, in their pursuit of economic growth, have recognized the limitations of an excessive focus on industrialization as a sole strategy for achieving higher per capita real income.
Industrial and agricultural development are not substitutes but rather complementary forces that mutually reinforce each other in terms of both inputs and outputs. Empirical observations indicate that enhanced agricultural productivity and output significantly contribute to a nation’s overall economic progress. Therefore, prioritizing the further development of the agricultural sector is both rational and essential.

3.1. Agriculture
• The term agriculture originates from the Latin words ager, meaning soil, and cultura, meaning cultivation.
• In its broadest sense, agriculture refers to the cultivation of crops and the rearing of livestock for production.
• It is essentially synonymous with farming, involving the field-based production of food, fodder, and industrial organic materials.
3.2. Economics • Economics is the science that studies as how people choose to use scare productive resources (like land, labour, capital and organiser) to produce various goods and to distribute these goods to various members of the society for their consumption.
3.3. Agricultural Economics
• Agricultural economics is a branch of applied economics that applies the principles of choice to the efficient use of scarce resources such as land, labor, water, seeds, and fertilizers in farming and related activities.
• It focuses on guiding farmers in the optimal utilization of land, labor, and capital.
• Its significance lies in providing practical solutions to help farmers maximize income while managing limited resources effectively.
3.4. Definitions
1. Prof. Gray has defined agricultural economics as “The science in which the principles and methods of economics are applied to the special conditions of agricultural industry”.

Every science has its own language. Economics has its own language. There are certain terms which are used in a special sense in economics. So we must understand the meaning of some basic concepts in the field of economics are discussed below.
2.1. Goods
Anything that can satisfies a human want is called a good in economics. For example: Foodgrain, pulse, oilseeds, machinery, seeds, fertilizer, pen, book, etc.
2.2. Services
A service refers to an act or performance that one party provides to another. Services are characterized by their intangible, non-material nature, as well as their inseparability, variability, and perishability. Examples include the services offered by doctors, teachers, lawyers, engineers, and laborers.

1.1. What is Economics?
If we see our day-to-day activities, most of which are related to earning one’s own living and to the manner of satisfying one’s own wants. These human activities, which are generally called economic, are mainly related to production, distribution, consumption and exchange of goods and services. The scientific study of various problems arising out of these economic activities is called economics.
1.2. Basic Economic Problem
The basic economic problem is Human wants are many; but means to satisfy these wants are limited. These limited means are capable of alternative uses and hence there is a need of satisfying maximum wants with limited resources. In reality most resources are scarce. Similarly, Individuals and nations possess boundless desires, yet they are constrained by a finite pool of resources, including labor, machinery, factories, and raw materials. These scarce resources can be allocated in multiple ways to fulfill various needs. Likewise, individuals have limited financial means but an array of wants they aspire to satisfy, necessitating careful decision-making regarding resource utilization.
For instance, a farmer has the option to cultivate crops such as paddy, sugarcane, banana, or cotton on his garden land. However, the choice of crop must be made based on the availability of irrigation water, as different crops have varying water requirements. More example are shown in figure 1.

It is crucial to understand that our entire health and wellbeing depends centrally on our mental health. A broad spectrum of mental health issues that impact our mood, thoughts and behaviours may lead to stress, sadness, anxiety inappropriate eating disorders, addictive behaviours and many more. People occasionally face mental health issues, but when persistent symptoms impair functioning and cause regular stress, a mental health concern turns into a mental disease. It also affects how we respond to people, deal with stress and make decisions.
From infancy to adolescence mental health is very crucial for healthy development as it lays the foundation for development of positive social, emotional, cognitive and communication skills and behaviours in young people and that boost the mental health and wellbeing in later life.
Why Is Mental Wellbeing Important?
According to estimates from the World Health Organization, 20% of young people suffer from mental problems and the incidence are growing faster (World Health Organization). Greater numbers signify a greater effect and are more serious. Globally, mental, behavioral and neurological disorders are predicted to account for nearly 15% of disability-adjusted life years by 2030; number of years that an individual was “lost” to living with the aftereffects of a certain disease or lived with a handicap. However, the prevalence pattern varies among high, middle and low-income countries (Prince et al., 2007).

Mental health prevention entails intervening to reduce mental health problems by addressing underlying factors before a specific issue arises in an individual, group or population. The primary objective is to decrease the occurrence of future mental health problems. Mental health promotion and prevention strategies seek to enhance an individual’s emotional regulation capabilities, promote healthier alternatives to risky behaviors, cultivate resilience in managing challenges and adversities and foster supportive social environments and networks. These initiatives lie at the heart of a public health approach to children and youth mental wellbeing, emphasizing the importance of optimizing positive mental health while also preventing and addressing mental health issues.
Adolescence represents a critical period for mental health vulnerabilities. The World Health Organization (WHO) reports that approximately half of all mental health conditions manifest by the age of 14, often remaining unidentified and untreated. Nonetheless, proactive preventive measures can yield significant benefits. The latest WHO report highlights the “numerous opportunities for health promotion and disease prevention during adolescence, which could have positive effects on young individuals in both the short and long term.” The WHO guidance advocates for the implementation of preventive psychosocial interventions among youth to mitigate or prevent the potential longterm consequences of mental health conditions.

Positive psychology plays a pivotal role in the well-being of adolescents by addressing their strengths and nurturing a growth mindset. It emphasises cultivating resilience, fostering optimism, and instilling gratitude rather than focusing on challenges only. This approach aids young individuals in developing a positive outlook on life, thereby enhancing their mental well-being and overall sense of contentment. By prompting to enhance their strengths, positive psychology equips them with the necessary skills to navigate obstacles and setbacks, resulting in enhanced academic achievements, stronger social connections, and heightened self-confidence. Essentially, it transforms potential hindrances into opportunities for personal growth and prosperity.
The well-being of adolescents is significantly affected by the domestic environment, underscoring the paramount importance of parenting. Parenting is often perceived as an inherent aptitude, typically acquired from one’s parents and through firsthand experience in child-rearing. Despite divergent perspectives on what constitutes ‘effective’ parenting, child psychologists universally acknowledge its pivotal role in fostering robust development, social integration, academic achievement, and self-assurance. Authoritative parenting – characterized by a blend of parental authority and profound attentiveness to the child’s needs – is widely regarded as the optimal approach to nurturing psychologically resilient children (Baumrind, 1991, 1993).

The typical way of living that reflects one’s attitude and values is called lifestyle of the person. A person’s lifestyle is shaped by one's specific geographic, economic, political, cultural and religious context. A lifestyle is a means of forging a sense of self and to create cultural symbols that resonate with the personal identity. According to WHO lifestyle is “a specific type of behaviour that can reduce disease and early death by personal physical, mental and social interaction”.
Lifestyle refers to the interests, opinions, behaviors and orientations of an individual, group or culture. The term was introduced by Austrian psychologist Alfred Adler in his 1929 book, The Case of Miss R., where he described it as “a person’s basic character established early in childhood.” Since 1961, the broader sense of lifestyle as a “way or style of living” has been recognized. Lifestyle is influenced by both tangible and intangible factors. Tangible factors include demographic variables, such as an individual’s demographic profile, while intangible factors involve psychological aspects like personal values, preferences and outlooks.
Lifestyles vary significantly between rural and urban environments. Even within urban areas, the nature of the neighborhood affects the lifestyles available to residents, influenced by factors like affluence and proximity to natural and cultural environments. For instance, coastal areas often have a surf culture or lifestyle. A lifestyle typically reflects an individual’s attitudes, way of life, values or worldview. It serves as a means of forging a sense of self and creating cultural symbols that resonate with personal identity. However, not all aspects of a lifestyle are voluntary. Social and technical systems can limit the lifestyle choices available to individuals and the symbols they can project to others and themselves.

Introduction
Psychotherapeutic measures provide a treatment approach to help a person identify and alter disturbing emotions, thought and behaviors.
They include targeted strategies that are used to deal and alleviate mental disturbances. Contemporary approaches are customized techniques to effectively and efficiently delivering solutions to the problems and their manifestations. The history of treatment throws light upon several conventional approaches to deal with multiple disorders. The following discussion provides the insight into the understanding of these approaches: -
1. Psychodynamic Therapy (PDT)
Psychodynamic therapy was the norm in psychiatric practice in the early 20th century. It evolved primarily from Sigmund Freud’s psychoanalytic ideas, with significant contributions from Karl Jung, Anna Freud and Melanie Klein, among others. The main emphasis is on how early experiences shape and build the psychological systems that are mostly responsible for the unconscious. Finding, exposing and resolving suppressed tensions from previous interactions that inadvertently surface in current interpersonal interactions and give rise to maladaptive behavioral patterns is the aim of psychodynamic therapy. Free association and dream analysis are two methods used to investigate the unconscious drive. The patient is urged to express himself freely and without restraint during free interaction. Using “active listening,” the therapist searches for references or patterns that connect to ongoing developmental and interpersonal issues. This can aid in understanding the unconscious process. The application of dream

Disorders of Children and Youth
Although it is sometimes assumed that childhood and adolescence are times of carefree bliss, as many as 20% of children and adolescents have one or more diagnosable mental disorders. Most of these disorders may be viewed as exaggerations or distortions of normal behaviors and emotions. Childhood mental and developmental disorders encompass neurodevelopmental, emotional and behavioral disorders that have broad and serious adverse impacts on psychological and social wellbeing. Children with these disorders require significant additional support from families and educational systems. These children are more likely to experience a compromised developmental trajectory, with increased need for medical and disability services, as well as increased risk of contact with law enforcement agencies (Fergusson and others, 1993).
Like adults, children and adolescents vary in temperament. Some are shy and reticent; others are socially exuberant. Some are methodical and cautious and others are impulsive and careless. Whether a child is behaving like a typical child or has a disorder is determined by the presence of impairment and the degree of distress related to the symptoms. For example, a 12-yr-old girl may be frightened by the prospect of delivering a class report in front of her class. This fear would be viewed as social phobia only if her fears were severe enough to cause significant impairments and distress. The mental disorders that children can develop are commonly divided into two groups: disruptive or externalizing behavior disorders (e.g., attention-deficit hyperactivity disorder, conduct problems) and emotional or internalizing behavior disorders (e.g., anxiety, depression). In this unit we would focus on types of internalizing and externalizing disorders in children. We will also discuss in depth the etiology and treatment involved in these disorders.

DSM-5 and Diagnosis of Mental Health Issues
Mental health is a fundamental aspect of overall wellbeing and the accurate diagnosis of mental health issues is crucial for providing appropriate and effective treatment. The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) is the latest reference guide used by mental health professionals to diagnose mental health conditions (Kapadia et al., 2020). The current edition, DSM- 5, builds on the goal of its predecessors of providing guidelines for diagnoses that can inform treatment and management decisions. The DSM-5 provides a comprehensive and standardized framework for the classification and diagnosis of mental disorders.
The DSM-5 represents a significant advancement in the field of psychiatry, as it incorporates a cross-cultural assessment of mental health issues and an updated classification system. (Petito et al., 2020) This detailed diagnostic criteria helps clinicians accurately identify and differentiate mental health conditions, enabling them to develop tailored treatment plans.

Hazards to mental health include a range of circumstances that may affect a person’s mental health. A complex and multidimensional component of total health, mental health is impacted by biological, psychological, social and environmental variables. Promoting mental wellbeing and avoiding mental health difficulties need an understanding of these risks and taking appropriate action. Global initiatives to promote health continue to overlook mental health. People with mental health disorders frequently face serious human rights abuses, discrimination and stigma, regardless of advancements in certain nations. More than 80% of those with mental health issues, among them with neurological and drug use problems, lack access to any kind of high-quality, reasonably priced mental health treatment. Even though there are many effective, economical treatments for mental health issues, there is still a substantial disparity between those who require care and those who have access to it. Coverage of effective treatments is still incredibly low. Mental health conditions have a significant effect on happiness, productivity and overall health. Mental health issues have significant emotional, societal and financial implications. These consequences include those associated with the criminal justice system, medicinal and educational services, unemployment and sick leave.
Adolescent mental illness is more than just being miserable. It may affect a teen’s life in many ways. Young people who are mentally ill may have difficulties making decisions, managing their health and succeeding in school. One of the main causes of sickness and impairment in young people are mental health issues, which include childhood epilepsy, developmental disabilities, depression, anxiety, mood, attention and behavioural disorders. Neglecting children’s and teenagers’ mental health and psychosocial development has long-term effects that follow them into adulthood and reduce their chances of living happy, satisfying lives.

What causes lead to mental illness? Although the exact origin of the majority of mental health problems is unclear, research indicates that many of these diseases are caused by a combination of biological, psychological, environmental and socioeconomic factors.
Many mental illnesses are passed down through family lineage. However, it doesn’t imply that just because one or more of one’s ancestors had an illness, they will compulsarily inherit it too. But just because your mother or father had one does not mean you will.
Some illnesses impair brain circuits that control thought, emotion and behavior. Within particular circuits, for instance, certain brain chemicals known as neurotransmitters may be activated excessively or insufficiently. Certain mental diseases are also linked to brain injury.
Mental health illness in adolescence are a significant problem, relatively common and amenable to treatment or intervention. Mental disorders and mental health problems seem to have increased considerably among adolescents in the past 20-30 years. The rise has been driven by social change, including disruption of family structure, growing youth unemployment and increasing educational and vocational pressures.
The prevalence of mental health disorders among 11 to 15 year olds in Great Britain is estimated to be 11%, with conduct problems more common among boys and depression and anxiety more common among girls. The identification, treatment and follow up of mental health problems in young people can be complicated. Parents and teachers may dismiss problems as merely reflecting adolescent turmoil. Young people are often very reluctant to seek help, owing to developmental needs about being “normal” at the time when they are exploring identity issues and trying to engage with a peer group.

In today’s world, where youngsters face inevitable stress and pressure, wellbeing has gained significant importance. Since research began in the field of mental wellbeing, psychologists have increasingly focused on ‘quality and satisfaction of life,’ making it a popular topic. Quality of life and life satisfaction measure an individual’s perceived level of psychological wellbeing, wellness and happiness, often used interchangeably with subjective or general wellbeing. Mental wellbeing can be described as the overall mental state of an individual who is well-adjusted to their environment. This includes feelings of contentment, enjoyment, happiness, satisfaction with life experiences, job satisfaction and a sense of achievement and belonging. Additionally, it encompasses the ability to manage grief, distress, dissatisfaction, fear or worry in personal and social life. Due to the difficulty in objectively measuring these parameters, the term ‘subjective’ or general wellbeing is emphasized. This concept generally promotes a subjective sense of wellbeing, influencing individuals’ attention to self-care and emotional wellbeing.
Researchers studying subjective or general wellness often view it as a multi-faceted domain rather than a single construct (Pavot and Diener, 2003). Diener, Suh, Lucas and Smith (1999) define subjective wellness as a broad category that includes people’s emotional responses, domain satisfaction and overall life satisfaction. The concept of wellness encompasses both physical and mental health, as well as moral and ethical values. Life is not always smooth; people encounter failures, frustrations and disappointments. It is the mental strength and wisdom of a person that helps them move forward and emerge from life’s occasional darkness to achieve wellness. Maintaining mental balance amid life’s difficulties is crucial for achieving one’s goals.

Mental wellbeing in youngsters is not merely the absence of mental illness; it encompasses a state of positive psychological functioning, where individuals are able to manage their emotions, build healthy relationships and navigate the challenges of life. This period is characterized by significant physical, emotional and cognitive development, making it a critical time for establishing the foundations of mental health.
Mental wellbeing is a crucial aspect of overall health, especially during the formative years of childhood and adolescence. In the contemporary scenario, for youngsters, the journey to mental wellbeing is a complex interplay of biological, psychological and social factors. This journey is increasingly shaped by rapid societal changes, technological advancements, academic pressure, family dynamics and global crisis such as the COVID-19 pandemic. These influences have profound implications for the mental health of young people, making it essential to explore the current challenges and opportunities in promoting mental wellbeing among this demographic.
Psychological Development During Adolescence
Adolescence is a time of significant psychological change, marked by the development of identity, self-concept and emotional regulation. During this stage, youngsters begin to form their own beliefs and values, separate from those of their parents or guardians. They also develop the capacity for abstract thinking and moral reasoning, which allows them to engage with complex social issues and make independent decisions. These developmental processes are influenced by a range of factors,
