4.1 Introduction

The wind is caused by the motion of air. In different regions, there are pressure differences that cause winds. There is a tremendous amount of energy carried by them. The use of wind energy can be profitable in regions with strong winds for a significant part of the year. The wind is a form of solar energy. The wind is caused by uneven heating of air and land by the sun. The earth’s rotation and geological irregularities also play a role. Heating causes air to rise, and cooling causes cooler air to fall to fill the space. As a result, the air mass moves. On a global basis, the poles exert a primary forcing function that allows the equator to receive surface winds from the poles. 

5.1 Introduction

Biomass energy is the energy obtained from biomass or living things. Biomass is renewable organic material that comes from plants and animals. Plants generally produced through the process of photosynthesis as shown in Figure 5.1. Biomass is organic, meaning it is made of material that comes from living things, such as plants and animals. Wood, plants, and waste are the most common biomass energy sources. These are called biomass feedstocks. A plant absorbs the sun’s energy through photosynthesis and converts carbon dioxide and water into nutrients (carbohydrates). The energy from these materials can be transformed into usable energy through direct and indirect means. Biomass can be burned to create heat (direct), converted into electricity (direct), or processed into biofuel (indirect).

6.1 Introduction

Biomass pellets are one of the most common types of biomass fuel. It is generally composed of wood waste, agricultural biomass, grasses, and forest residues, and is one of the most popular types of biomass fuel available today. Pelletization of biomass results in significant savings in terms of transportation, and storage, as well as the ease of handling biomass as a whole. In terms of flowability, dense cube pellets are similar to cereal grains in terms of their characteristics of being dense and cube-shaped. Due to their regular geometry and small size, biomass pellets are easily fed through an automatic feed system with fine calibration thanks to their regular shape. Because pellets are so dense, they can be stored in a compact way and transported over a long distance in a rational and efficient manner, because of their density. Furthermore, pellets can also be produced with a low moisture content, even though they are extremely dense. This allows them to burn with a high degree of combustion efficiency due to their low moisture content.

7.1 Introduction

A biodiesel fuel is an environmentally friendly, renewable, biodegradable fuel that is produced at domestic facilities from vegetable oils, animal fats, or recycled grease from restaurants. In accordance with the Renewable Fuel Standard, biodiesel meets the requirements for biomass-based diesel as well as the requirements for advanced biofuels as a whole. Biodiesel is distinct from renewable diesel, also known as “green diesel.” In its pure, unblended form, biodiesel is also known as B100 or neat biodiesel. Biodiesel is used to fuel compression-ignition engines in the same way as petroleum diesel. Alternatively, biodiesel is a liquid biofuel that can be used in diesel engines alone or blended with diesel oil. The fuel is obtained through the chemical conversion of vegetable oils or animal fats combined with alcohol.

8.1 Introduction

Biogas is produced by the anaerobic digestion of biodegradable materials with the help of microorganisms. Biogas is also considered as renewable energy source because of is environment friendly nature. Conversion of cattle dung, kitchen wastes and agricultural wastes into biogas have the potential to minimize the burden on the fossil fuel and reduce the environmental pollution. Majority of developing countries specially their rural and suburban areas faces lack of access to the electricity and cooking gas. Biogas technology is emerging as a sustainable technology for waste treatment which could help to tackle the waste disposal issue in developing countries. 

9.1 Introduction

Hydrogen is colourless and odourless gas. Hydrogen is simplest and lightest element and most abundant available element on the earth. It is not primary energy source as it does not exist in free state however it presents in compound with oxygen (water) and carbon, nitrogen and oxygen in living material and fossil fuels (natural gas, coal and biomass). Therefore, hydrogen can be produced from these sources using some external energy. Hydrogen can be burned without generating CO₂ and have clean combustion. but with air it can form very explosive mixture. Hydrogen is considered as an energy carrier. Like energy carrier allows the transport of energy in usable form from one place to another. 

10.1 Introduction

As one ofthe oldest and most widely used renewable energy sources, hydropower generates electricity by using the natural flow of flowing water. Streams and rivers have been used for producing mechanical energy for thousands of years. Hydroelectric power plants are located near or on water sources since they derive their power from flowing water. The amount of energy that can be released in moving water depends on the volume of the water flowing and the elevation change from one point to another, often called head. Generally, hydropower plants can produce more electricity when there is more water flow and a higher head. 

11.1 Introduction

More than 70% of Earth’s surface is covered by the ocean, the world’s largest solar energy collector and storage system. By utilizing only a small portion of this energy, we can meet all the energy needs around the world. As long as the sun shines and there are natural ocean currents, Ocean Thermal Energy Conversion (OTEC) energy source is free, abundant, and continually replenished. It is estimated that 3 to 5 terawatts (1 terawatt is 1012 watts) of baseload power generation can be practically harvested without affecting ocean temperatures or the environment of the planet. this is about the twice the global demand for electricity. Oceans are therefore an abundant renewable resource, offering a sustainable method for the production of electricity in the future. 

12.1 Introduction

A magneto hydrodynamic energy conversion system or MHD system converts heat energy directly into electricity. An MHD generator produces electricity via the interaction of a moving fluid with a magnetic field and ionized gas. MHD conversion does not involve any mechanical conversion intermediary. As a result, this process offers substantial fuel savings because the process of producing mechanical energy and then converting it to electrical energy is eliminated. It is possible to generate electricity in large quantities using MHD power plants while reducing the impact on the environment. During his Bakerian lecture in 1832 to the Royal Society, Michael Faraday presented the concept of MHD power generation for the very first time. 

13.1 Introduction

At a national level, the agricultural sector is one of the major potential users of energy in the Indian context. Further, it is often highly dependent on the supply of electricity and fuel in order to function properly. The term “agriculture” refers to all on-farm activities required for farming, raising animals, and associated activities associated with farmers, growers, and entrepreneurs. Fuels such as petroleum and electricity are primarily used for the operation of pump sets and other operations. In the future, this may result in problems with supply and price. Moreover, India has relatively small reserves of crude oil and will eventually be forced to import more crude oil to make up for the lack of reserves. In order to save energy and money on the farm, farmers must identify opportunities for energy conservation on the farm in order to maximize energy efficiency. 

1.1 Introduction

Climate change is evident from the observation of increase in global average air and ocean temperatures, precipitation and extreme rainfall, widespread melting of ice, storms / storm surges flooding and rising global mean sea level, as recorded in the Fourth Assessment Report of IPCC. Eleven of the last twelve years (1995-2006) rank among the twelve warmest years in the instrumental record of global surface temperature (since 1850). 

2.1 Introduction

Agro-meteorological advisories relate the past, current and predicted future weather to agricultural activities. Behaviour of weather both in space and time, considerably affect the agricultural production. Year to year variations in crop production are generally depended to the abnormalities in the behaviours of weather. The mission of the Agromet Advisory Services (AAS) of NCMRWF is to maximise farmers’ profits by decreasing losses due to weather calamities and also by increasing the timeliness of operations in the crop field. An ideal AAS bulletin helps to reduce environmental pollution through the optimum use of chemicals in the crop filed. An ideal AAS bulletin should contain farm management information to weather based agricultural operations and available to the farmers in real time.

3.1 Introduction

One of the most important functions to the AAS units is to widely disseminate the advisory bulletins among the user community. A unit cannot be considered operational unless its bulletins are reaching the target masses. The dissemination is one way communication which is broadly speaking the process by which human beings share information, knowledge, experience, ideas and motivation. 

4.1 Introduction

The livestock/poultry have great capability for climatic adaptation and acclimatization. However in an open environmental condition their overall well-being and efficiency depends on day-to- day weather conditions. While certain breeds of livestock and poultry are considerably flexible to adjust themselves with the varying weather conditions, the others may have little adjustability. This has led to the development of weather/climate based livestock/ poultry management practices which include the general care. Nutrition and health managements for optimizing conditions for best yield in respect of milk, meat, eggs, wool, load carrying capacity etc. have been properly documented. 

5.1 Introduction

Weather is one of the most important factors which determine success or failure of agricultural production. It effects every growth phases and development of plant. During the growing period of the crop, any variability in the weather condition such as delay in monsoon, excessive rainfall, drought, flood, heat or cold wave affects the crop growth and finally reduces the quality and quantity of crop yield. These losses due to weather hazards can be reduced by taking proper crop management in time and by applying accurate weather forecast. Weather forecast also provides guidance for selection of crops and varieties best suited to the local climatic condition. 

6.1 Introduction

One of the key challenges in the 21^st century is that Agromet Advisory Services (AAS) have to respond to an unpredictable and changing climate. In India Gramin Krishi Mausam Sewa (GKMS) is the umbrella project for Agromet Advisory Services (AAS) and it intends to link AAS to different sources of knowledge and innovations to respond to the climate change at root level farmers. The main aim of GKMS is to create effective, efficient and synergistic linkages to improve the delivery of these AAS to the farmers. GKMS works under the frame work of India Meteorological Department (IMD) which seeks to enhance the livelihood of every Indian farmer. 

7.1 Introduction

The occurrence of extreme weather events like drought and flood is increasing in Bihar due to climate change. Bihar receives nearly 80% of annual rainfall during June to September which is quantitatively enough for growing most of the crops. However, aberration in temporal and spatial distribution of rainfall makes the crops vulnerable to drought as well as flood. Rainfall is the most important factor for planning of crop production in rainfed areas. The information on annual, seasonal and weekly rainfall of a region is helpful to design different agricultural operations like field preparation, sowing, irrigation, fertilizer application as well as overall crop planning (Singh et al., 2008). Zone I and zone II of Bihar are receiving too much rainfall which causes flood in this region whereas zone III B is identified as rainfed region which has low, erratic and uncertain rainfall pattern with frequent dry spells during the monsoon season. Hence kharif cropping is tricky operation in this region and sudden crop failures is a common phenomenon due to frequent dry spell or early withdrawal of monsoon. In India many scientists studied on rainfall probability pattern (Suchit et al., 2012) and they concluded that rainfall occurrence is certain at greater than or equal to 80 % probability, while 50% probability is the medium limit of certainty and may involve dry spell risk. Based on these climatic and probability factors, the study was carried out for four different locations situated in different agro climatic zones of Bihar for interlinking the rainfall probability pattern with the crop planning pattern in those regions.

Introduction

Women and girls in rural areas bear the brunt of poverty, feminisation and its intergenerational ramifications and the effects of desertification, extreme weather events, and natural disasters. Women are most at risk in conflict situations, as migrants and refugees and in humanitarian crises. Rural women have higher rates of disability, have inadequate or non-existent support services, and are stigmatised. Despite being the leading food growers and processors, the paradox is that they are often the last to consume the nutritious and healthy food they need to stay strong.

Women have contributed significantly and selflessly since ancient times to uplifting and bettering any nation. A literate woman builds a country; truth cannot be closer than that. Women have always carried the burden of being a wife, mothers, sisters and daughters, all on their own magnificently. They are leaders, decision-makers, entrepreneurs and service providers in different fields. The valuable contributions of women are significant to the well-being of families and communities and the economic growth of any society. Rural women have tremendous potential for developing culture, and their leadership, participation, and education will help eradicate poverty and hunger.

The core concept of empowerment is the idea of power and thought of control. Empowerment is the process of strengthening, encouraging, obtaining opportunities, and mobilizing assets and resources for the welfare of individuals, groups or masses. Over the past two decades, discourse and focus on the concept of empowerment have steadily and relentlessly increased within international development discourse. Empowerment has evolved to develop a more extensive physical and mental well-being, freedom from domestic violence, unpaid work and reproductive health. However, the wealthy body of work has wrangled the thought of empowerment of women.

Our country today is considered independent. We have the freedom to live by our choices, and there is no discrimination between women and men. Nowadays, women and men get equal opportunities to earn their livelihoods. Women’s work is restricted to the households and jobs outside the home to contribute to the family’s economy. As industrialization occurs, the demand for labour and employees is also increasing. This has created opportunities for both women and men to work equally.

Rural Indian women are extensively involved in agricultural activities. In rural Uttarakhand, women contribute about 90 per cent of the total work in agriculture and animal care. Women’s participation rate in the State’s economy is much higher than in several states and the national average. In Uttarakhand, women’s role ranges from managers to landless labourers. Women’s average contribution is 55% to 66% of the total labour in overall farm production, with percentages higher in certain regions. From a demographic perspective, nearly 17% of households are women, higher than the national data (~11%). The main reason for this shift is migration other than divorce, separation or widowhood.

Almost half of the population in the world comprises women, indicating that women are at par with men, but the issue is ‘Is she really at par with men in the status too?’ Numerous studies have drawn attention to the fact that women are half marginalised in every society; they have not yet got their share. The concern over women’s problems started with the establishment of the United Nations in 1945, which led to the declaration of 1975 as ‘International Women’s Year’ and the years between 1975- 1985 as the UN Decade for Women. For the first time, the attention was focused on the unnoticed and forgotten halves, who by birth were women, performing 2/3^rd of the world’s work, receiving 1/10th of the world’s income and owning less than 1/100^th of the world’s property (Rath, 1996). 

Pulses are widely acknowledged as superfoods, three times the protein in rice and double in wheat. Besides, they are also rich in complex carbohydrates, micronutrients, protein and B-vitamins and minerals like folate, iron, calcium, magnesium, zinc and potassium. High iron content in some pulses also minimizes the risk of anaemia. Long storability without loss of nutritional value, low prices, and broader availability make pulses an affordable source of minerals, and protein, thus contributing to food security at all levels of society in India. Besides human nutrition, pulse crops are also utilized as fodder and fuel for farm households.

India has experienced marked changes, both at international and national levels. Technological progress, ICT penetration in rural and urban areas, and changes in current government policies have resulted in changes in the country’s social structure and power relations. The government initiated various programmes like Rashtriya Mahila Kosh (RMK), Development of Women and Children in Rural Areas (DWCRA), Mahila e-Haat, and Support to Training & Employment Programme (STEP) etc. are there to improve the state of rural women. 

The informal associations of individuals who come close to seeking ways to enhance their living conditions are known as Self Help Groups (SHGs). They are generally self-governed and peer-controlled. An NGO or Agency usually governs people of comparable economic and social backgrounds to resolve their issues and improve their living conditions. It is a local committee of 10 to 20 women or men between 18 to 40 years. It acts as an intermediary financial committee. Self-help groups are a gaggle of each person on daily wages, and among that group, one person collects the cash and provides the case desired to the person in need.

Women have been seen as necessary as a man. The status of the women and the work progress of the women have been seen as a nation’s overall progress. Without the penetration of women in socio-economic and political activities, the country is considered to stagnate. Still, the devaluation of women commences at birth with the preference for male offspring. This continues through childhood conditioning to the submissive and, later on, the subservient role required of them in the marital home.

The decadal Census, 2011 puts India’s population at 121.08 crores (cr.), split into 83.37 cr. of rural and 37.71 cr. of urban inhabitants. Of the total population, the working population was 48.18 Cr. comprising primary workers at 36.25 cr.

Regarding gender analysis, the male and female populations counted 62.32 and 58.75 crores, respectively. The female population was rural-dominated,with 42.77 crores living in villages and 10.51 crores in urban centres.The Census also showed that the women accounted for a substantive size of the working population, 14.99 crores (12.19 rural+2.80 urban). The primary workers of this female working population were as high as 8.93 crores, with 6.77 crores living in rural India and 2.15 crores in urban centres. The details may be seen in Table 1.

Although women work in household chores, agricultural activities, factories, and different workplaces in days of yore, their valuable work is still not recognized as a financial entity (Kathrivel and Sivakumar, 2003). The multiple roles performed by ‘Nari shakti share many working hours, but financial terms are off the records. Women’s power at construction work is greater utilization as labour and their daily routine employment. 

People worldwide are getting affected by the changing climate and associated natural disasters. These climate changes affect both genders differently. Changing climate is not often thought of as an issue related to gender, yet it is increasingly evident that women are more affected by its impacts. Women of all ages are more vulnerable due to persistent cultural norms and low socioeconomic status. Women’s domestic roles often make them inconsistent users of nature-based resources such as firewood, water, and forest products. When these resources become scarcer, they experience an increased work burden. This is proved by many researchers that women in developing countries share the primary responsibility of providing basic needs like food (to feed) and water for their families; this is the cause behind their dependency on natural resources.

ountains occupy twenty-four per cent of the global land surface area (about 25 million km²) and are home to twelve per cent of the world’s population (GTOS, 2008). Water is present in snow, glaciers, wetlands, and rivers in the mountains. They supply watersheds by providing groundwater recharge to hill communities and communities living in vast basin areas (Hua, 2009). Whatever happens in these mountains affect nearly 1.2 billion people, one-fifth of the world’s population living in the river basins, and up to three billion indirectly in food and energy production. Despite harbouring some of nature’s richest natural resources, mountains are home to some of the world’s poorest people, many of whom are marginalized subsistence farmers. These communities living in the mountain region have hardly benefited from the ‘green revolution’ and global economic growth.

Corporate Social Responsibility (CSR) is generally a policy to assess its impact on society and estimate its societal responsibilities. The CSR plan of any organization ensures that it complies with government norms, their investments in respect of growth, development of weaker sections and the environment. CSR’s primary requisite should be sustainable, involving interventions that an organization can justify without negatively affecting its profit goals.

s per the advancement in technology, our society is steadily moving towards adapting the new ordinary technologies for their normal affirms of life. While many’s daily lives are far from ordinary, one critical enabler for humans to survive and sustain their livelihood has been the accelerated adoption of digital technologies, especially in the last two years. We have witnessed how things happened because of the emerging technology in various sectors: education, business, communication, interaction, socialization, professional work, agriculture, etc. This will be the norm for the new normal and the “Gig Economy” evolution. Technology disruption has helped almost everyone in their many walks of life. When we consider the rural women at large, technology has, directly and indirectly, helped each procure food and other commodities to manage their livelihood. 

Empowerment in the women’s development context can be defined as defining, challenging, and overcoming the hurdles in women’s life. She enhances her ability to mould her life, personality, and surrounding environment. The buzzword “empowerment” synchronises with women metaphorically when we think of women empowerment. Such has been the issue and its importance in society today. However, why it matters so much can be attributed to “constraints”. 

Rural development is transforming the lives of the rural people by creating awareness and mobilizing the people for self-help and pastoral help. Rural development is not new in India, where more than 70% of the people live in villages, their primary source of livelihood being agriculture, animal husbandry etc. Any area’s development initially occurs when changes happen in the home and family. Rural development focuses on the holistic development of the rural population by helping them to recognize their needs & interests and guiding them to meet them. This would result in personal, social, economic, and spiritual development.

A woman is the backbone of the family. The Self-reliance of women is the first step in the nation’s development. For generations, women have fought for their existence. Women’s softness and humility have developed new dimensions of self-reliance; as a result, the image of a woman with a veil of weakness has ended.

The position of women in ancient times was excellent. The most significant decline occurred in the status of women during the Mughal period. 

Education: Education is the production of desirable changes in the behaviour of the people. It is the production of desirable changes in human behaviour in knowledge (things known), attitudes (things felt) and skills (things done), in all of them or in one or more of them.

Behaviour: Includes three components viz., knowledge, attitude and skill

Knowledge (Cognitive): It includes facts, concepts, principles and relationship.

Attitude (Affective): An attitude can be loosely defined as a feeling towards some object, person and situation or idea.

Programme Development

Programme development is an on-going dynamic process that extension professionals intuitively follow as they plan, implement and evaluate their educational programmes. The process is not confined to a five-year planning cycle. It is applied on a small scale as an individual workshop is being developed, on a larger scale as a series of programmes are being developed around a single priority and on an even larger scale at district level and state level wide team sets priorities and defines a plan of action for a five-year period. The basic principles remain the same, only the scope is different. The gap between the situation and objective is the area of needs. This area becomes well-defined after the situations and the objectives are determined by the leaders, extension professionals and specialists.

Introduction

About 65 percent population of the country is living in the economically undeveloped area. Therefore, many evils such as illiteracy, superstitions, unhealthy practices etc. took roots in our country. After Second World War or after independence, it was thought to settle all these problems properly and so, many development programmes were reinvigorated. It is wrong to declare that there was nothing done during slavery period. However, those works, which were executed at that time, were very few in number according to the needs. Looking at a vast country like India, during British rule some selected social workers had started some programmes of rural development. The evolution of extension programme is described in two stages.

First Line Extension system

Realizing the scope and importance of integrated working of interrelationship between research, education and extension functions, the ICAR established a section of Extension Education at its headquarters in 1971, which was later on strengthen and renamed as division of agriculture extension. It was intended to enforces this functional relationship down the line in the research institute, agricultural universities and allied institutions.

Introduction of Training and Visit System

This Training and Visit system was developed by World Bank Expert Daniel Benor. Initially (13) Major states in India adopted Training and Visit system but later on most of the states are practicing this system since 1984 onwards.

Innovations in Field Extension

Of late, a lot of emphasis is being given on innovative extension approaches at the field level, in order to ensure an effective implementation of the Transfer of Technology (ToT) process. Many such new initiatives have been undertaken in India, the details of which are as under.

Farmer Field Schools - ANew Participatory Approach

Plans need not be made for nuts and bolts, but are essential to prevent future bottlenecks. If enough cushions are provided for the future, the economy will grow smoother and faster. The importance of plan is that when you design it before you implement it; you have a better chance of eliminating design flaws from the beginning. If you start out coding and later on figure out you have a design flaw, it is extremely painful to go back and re-implement everything. Certain software engineering experts have estimated that it can cost up to 10x more (time and money) to fix a design problem in the later stages of software development than in the early stages.

Rural development has always been an important issue in all discussions pertaining to economic development, especially of developing countries, throughout the world. In the developing countries and some formerly communist societies, rural mass comprise a substantial majority of the population. Over 3.5 billion people live in the Asia and Pacific region and some 63% of them in rural areas. Although millions of rural people have escaped poverty as a result of rural development in many Asian countries, a large majority of rural people continue to suffer from persistent poverty. 

The word ‘Democracy’ is derived from the Greek roots ‘demos’ meaning the people and ‘kratos’ meaning authority i.e. in democracy, all authority originates from the people. Decentralisation means distribution of functions and powers from a central authority to regional and local authorities. Democratic Decentralisation in the present context means that the Government which has derived its authority from the people, redistributes it to some extent to the people, for decision and action at the local level. This is popularly known as PANCHAYATI RAJ in India. It was thought that Panchayati Raj would emerge as a system of democratic local self- Government, discharging developmental municipal and ultimately, regulatory functions.

The four main projects of the transfer of technology projects of the ICAR.

The projects are:

1. All India Coordinated Project on National Demonstrations
2. Operational Research Project
3. Krishi Vigyan Kendra (Agricultural Science Centre)
4. Lab to Land Programme.

Community

1. A community is a group of people, who live in a geographical area and have an interest in each other for the purpose of making a living. It is a form of social organization existing between the family and state.
2. The people with common interests living in a particular area
3. An interacting population of various kinds of individuals (as species) in a common location
4. A group of people with a common characteristic or interest living together within a larger society

High Yielding Variety Programme (HYVP)

High Yielding Variety Programme (HYVP) was launched in 1966, which helped the country in attaining self-sufficiency in food. The technological development did not remain confined to the introduction of high yielding crop varieties alone. These were combined with the application of high analysis and balanced fertilizer, irrigation, plant protection, improved implements etc. which made a ‘Green Revolution’possible in the country.

National Agriculture Technology Project (NATP)

This project was launched by the ICAR on June 30, 1998, with the support of the World Bank to strengthen and complement the existing resources and to argument the output National Agricultural Research System (NARS).

Objectives

The major objective of this component is:

National Rural Employment Programme (NREP)

The NREP was launched in October, 1980 and became a regular Plan programme from April, 1981. The programme was expected to generate additional gainful employment in the rural areas, to the extent of 300-400 million mandays per annum, create durable community assets, and improve nutritional status and living standards of the poor.

An outlay of Rs. 1620 crores was provided under this Programme, out of which the outlay from 1980-81 onwards (Rs. 1280 crores) was to be shared equally between the Centre and the States.
