6.1. Introduction
The best way to combat malnutrition globally among women and children have changed over the last few years keeping pace with the advancement of technology. Information and communication technologies (ICT) have become very important for solving the contemporary nutrition related issues because they provide a vast array of new communication capabilities. In addition to meeting society’s actual needs for ongoing health and nutrition care, ICTs are crucial for facilitating interactive, personalized nutrition communication. People can interact or communicate with others in different countries in real-time through instant messaging, video conferencing or voice over IP (internet protocol). Through social networking platforms like Facebook, Instagram, and others, people from all over the world can regularly converse and stay in touch. In the context of health communication, ICT is referred to as Interactive Health Communication (IHC), which is the exchange of health information and advice and support regarding health-related matters between a consumer, patient, caregiver, or professional using an electronic device or communication technology. Nutrition treatments are less expensive when face-to-face interaction is facilitated by electronic means. These are complementary factors that encourage nutrition communication in an information-age healthcare system, especially when combined with consumers’ growing desire to take charge of their own health. Customers can advantageously use information technology in this system to connect with health professionals and support groups, obtain absolutely relevant information, and take charge of their own health. The “global village,” which has been made possible by modern information and communication technology, allows people to interact with each other virtually as if they were neighbours. Because of this, ICT is frequently examined in relation to the ways that contemporary communication technologies influence society.

7.1. Introduction
Entrepreneurs serve as the catalysts for the introduction of innovative technologies and systems that ultimately lead to societal advancements. These innovations are linked to enhanced lifestyles, progressive thinking, morale, and bravery, along with an improved standard of living. National and global changes are greatly influenced by such kinds of social change. Joseph Schumpeter, an Australian famous economist, is referred to as the father of entrepreneurship. Dhirubhai Ambani was the most enterprising Indian entrepreneur. Jamsetji Tata set a bar for entrepreneurship development in India with the foundation of the Tata group. The father of entrepreneurship in India is Ratan Tata. In public health, nutrition-based entrepreneurship and self-employment are also another emerging topic nowadays. Several entrepreneurs are found in this field mostly due to the challenge of building a business and craving to control their destiny. Not only that, financial independence, personal satisfaction, relief from the frustration of working for someone else, and the opportunity to create the desired lifestyle. Nutrition entrepreneurship offers numerous business-related resources and provides services for social well-being. As for example, the transformation of raw food ingredients into consumable food products, entrepreneurship plays a key role in diversifying and commercializing agricultural products. It adds value of food, prolongs its shelf life, promotes the export of processed items, generates employment opportunities, boosts farmers’ earnings, and makes a significant contribution to the general development of rural areas. Health entrepreneurs like nutritionists, dietitians, physicians, and health counsellors run their practice and make it available for the client to listen to their problems and solve their problems through mental support, motivation, diet therapy, medication, and so on. As a result, the health burdens due to noncommunicable and communicable diseases are reduced.

9.1. Introduction
The three basic need for human survival are- food, clothing and shelter. The requirement of food comes first. Human are omnivorous. They eat mainly natural foods. Before 5000 years ago, cereals were the main food for all civilization and then the complexity of life began to make appearing with the advent of industrialization, flourishing of industry and commerce. Unpolished grains were utilised at first, but in contemporary civilisation, we have begun to prepare them, which results in the loss of essential nutrients. The intake of meats, processed meals, and sugary goods has grown while the general intake of cereals has decreased. People now lack vital nutrients as a result of the departure from natural diets. People began to realise a few years ago that health is a significant concern in addition to flavour, convenience, and quality value. They have thus begun taking nutritional vitamin supplements to make up for the nutrients lost from processed meals. People are increasingly opting for natural nutraceuticals in capsules and tablets, a trend known as medicalization in nutrition, instead of relying on natural food items. Hippocrates emphasized the connection between food and medicine, stating that healthy foods has a strong therapeutic advantages. The ancient Indian medical system known as Ayurveda places a strong focus on the functioning of diet and nutraceuticals in both health and illness.
9.2. What are Nutraceuticals
Stephen De Felice, the founder and chief executive of the Foundation for Innovation in Medicine (FIM), first used the term “nutraceuticals” in 1989 to refer to the broad category of medicines and nutrition. Nutraceuticals are foods or dietary components that not only offer nourishment and energy but also significantly contribute to regulating and preserving the regular physiological processes that keep people healthy. Nutraceuticals included processed meals such as cereal-grains, soups or stews, genetically engineered foodstuffs, herbal items, nutritional supplements, and extracted nutrients. People are increasingly concerned about their healthy wellbeing these days. However, these include a hectic, sedentary lifestyle, unhealthy eating patterns, body image issues, and being afflicted by a number of illnesses. These are the factors driving the global nutraceutical market’s expansion and generating a lot of interest. Numerous health issues of the century, including cancer, type 2 diabetes, heart disease, inflammation, oxidative stress, constipation, and more, can be fought off with the use of these nutraceuticals. Overall, nutraceuticals bring an entirely novel phase in medical science and assist the food companies to promote more creative research strategies. (Dudeja and Gupta, 2017)).

Five major oilseeds are groundnut, sesamum, Rapseseed and Mustard, linseed and castor seed. India has the largest area and production of oilseeds in the world. Indian vegetable oil economy is the fourth largest in the world next to USA, China and Brazil.

Importance

• Oilseeds are sources of oil, protein, carbohydrates, vitamins like Vitamin A, D, E and K and also contain 18 essential aminoacids and trace elements.
• Edible oils are next to food grains in Indian diet.
• Vegetable oils are mainly (95-98%) triacylgycerols which are made up of one glycerol molecule and three fatty acid molecules. Quality of oil depends upon the nature and proportion of the fatty acids present in three triacylglycerols.
• Vegetable oils have a number of industrial uses such as soaps, detergents, plastic films, metallic foils, Condiments, Cosmetics, Plastic, Polymers, Organic coatings, Printing ink, Oiled cloth

5.1 Weeding and Interculture Equipment

The aim of weeding and intercultivation operation is to provide best opportunity to crop to establish and grow vigorously up to time of maturity. The main objectives of weed control are to improve the soil conditions by reducing evaporation from the soil surface, improve infiltration of rain or surface water, and reduce runoff to maintain ridges or beds on which the crop is grown and to reduce competition of weeds for light, nutrients and water. Mechanical methods of weed control are simple and easily understood by farmers. The tools and implements for mechanical weed control are mostly manual and animal operated. Manual method is most effective but is slow. It is popular in regions where labour wages are low and labour is easily available during the season. The additional cost of weeding using implements is comparatively less than the gains due to extra yields obtained. First weeding operation is mostly done between and along the rows. Remaining operations are done mostly between the rows. Hand hoes are generally used for removing weeds between plants in a row.

The influence of water quality on the soil and plant growth is related to the chemical and physicalproperties of the soil, the salt tolerance of the crop, the climaticregime of the area and the method,frequencyand the amount of irrigation water applied. Irrigation water quality refers to its suitability and sustainability for use in agricultural crops. The problems thatresultfrom the use of a particular irrigation water, vary both in kind and degree, and are modified by soil, climate and crop as well as by the skill and knowledge of the water user. As a result there is no set limiton water quality, rather itssuitability for use is determined by the conditions of use which affects the accumulation of water constituents andwhichmayrestrictcrop yield.The soilproblems mostcommonlyencountered and used as a basisto evaluate water quality are those related to salinity, water infiltrationrate,toxicityanda group of other miscellaneous problems. Numerous guidelines are available for evaluation of water quality. Time to time some of theseguidelines has been updated with modification of some criteria like SAR to Adj. SAR and the Adj. R_Na and development of new concepts like water qualityIndex (WQI) whichhave increasedour predictability. Thenewguidelines are relied heavily on old ones.The modified guideline by Ayers and Westcot (1985) was foundto be themost reliabletopredict thewaterqualityforirrigation.

Irrigated agriculture is playing a major role in enhancing food and livelihood security of a country. Supply of fresh water which is an importantinput for the sustainable and economic development of agriculture are not enough to meet the requirement of all sectors of economy. Reduced water availability to agriculture from the present share of 85% of country’s water resources to about 70-75% by 2020AD wouldaffect the capacity of the country to meet the food production target, unless supplies are augmented from unconventional sources. For future agriculture there are no alternatives but to rely on non conventional sources for partial alleviation of the forecasted water scarcity. Amongthese sources extraction of marginal quality groundwater and the waste water generatedfromurban and industrial activities have thepotential to augment the water supplies. Many associatedsoil, plant and environmental problems come up when these sources of water are directly used for irrigation. For addressing theseproblems and to get more benefit from thesesourcesof water, the first step is to understand how an irrigation water source affects the soil plantsystem.Thereforeknowledge of irrigationwaterqualityiscriticaltodevelop appropriate site and crop specific comprehensive short term and long term management programs.

The influence of the vagaries of weather on all species on the earth is ubiquitious. It exerts its profound influence on the health, moods and activities of the humans, on all the Agriculture operations right from the seeding stage to the harvesting stage and on the health, behaviour and production of the animal life. Crop growth, is influenced by the variation of the meteorological parameters such as temperature, rainfall and wind etc. It is estimated that in some countries the losses due to adverse weather conditions amount to as much as 30% of the annual agricultural production. This type of losses, many times prove disastrous in the countries whose economy is mainly agriculture based, like that of ours. While the favourable weather conditions increase crop yield, the adverse weather, damages the crop giving rise to very low yield. The weather elements play an important role in governing the crop performance. Similarly weather elements also found to be controlling the Livestock production. It hence becomes necessary for the agriculturists and the veterinarians to have some basic knowledge of Meteorology to get better equipped for problem solving in their respective fields. All the weather phenomenon whether beneficial or disastrous are enacted in the natural theatre which is called the atmosphere. Hence to start with one has to study the characteristics of the atmosphere before proceeding further in meteorology.

The atmosphere is a thin layer of gases surrounding the Earth?s surface, which is retained by the earth?s gravity. The atmosphere protects life on the earth by absorbing ultra violet solar radiation and reduces the temperature extremes between the day and night. The atmosphere has no abrupt cut-off. It slowly becomes thinner and fades away into space. There is no finite boundary between the atmosphere and space. Three quarters of the atmosphere by mass is within 11 km of the planetary surface. In fact half of the atmosphere is contained within 6km from the surface. The Karman line, at 100 km is frequently used as the boundary between the atmosphere and space. The atmosphere contains by volume roughly 78% nitrogen and 21% of oxygen, trace amount of other gases and water vapour. This mixture of gases is known as air. The atmosphere also contains water vapour in smaller quantities. The amount of all these gases except water vapour is more or less constant while the water vapour is highly variable and yet its presence is essential for the development of any weather phenomenon. Based on the thermal characteristics, chemical composition, movement and density, the atmosphere is divided into four distinct layers. They are troposphere, stratosphere, mesosphere & thermosphere. The first 64–80 km above the earth contains 99% of the total mass of the earth?s atmosphere and is generally of a uniform composition, except for a high concentration of ozone, known as the ozone layer, at 12–30 mi (19–50 km). Because of the pull of gravity the density of the atmosphere and the pressure exerted by air molecules are greatest near the earth?s surface. Air pressure decreases quickly with altitude, reaching one half of its value at about 5.5Km. The density of air at sea level is about 1.2 kg/m³. The atmospheric density decreases as altitude increases.

11.1. INTRODUCTION

Sorghum [Sorghum bicolor (L.) Moench] is the fifth most important cereal crop and is the dietary staple of more than 500 million people in over 90 countries, primarily in the developing world. It is grown on 47 m ha in 104 countries in Africa, Asia, Oceania, and the Americas. Among those, USA, Nigeria, India, Mexico, Sudan, China, and Argentina are the major sorghum producers globally. Sorghum grain is mostly used directly for food (55%), and is consumed in the form of porridges (thick or thin) and flat breads; however sorghum is also an important feed grain (33%), especially in Australia and the Americas. Stover (crop residue after grain harvest) is an important fodder source to both milch and draft animals in mixed crop-livestock systems. Sorghum is also a good source of green fodder due to its quick growth and high yield and quality of biomass. Of late, sorghum with sugar-rich juicy stalks (called sweet sorghum) is emerging as an important biofuel crop. Thus sorghum is a unique crop with multiple uses as food, feed, fodder, fuel and fiber. Sorghum is generally grown in rainy season (spring) but in India it is grown in both rainy and postrainy seasons. The postrainy season sorghum grain is prized for its food value (Reddy et al., 2009).

Large number of edible fruits exists in tropics and subtropics of world. Many of such fruit species are identified, domesticated and are being utilized for various purposes, though their full potential has not been exploited. There is yet another group of plants producing edible fruits with great potential in different parts of world, which are not at all being grown and utilized by people other than in a very localized manner. Such under and un-utilized fruits are made the subject for detailed study. They are evaluated for their nutritive value, potential uses for other purposes, for possibilities of commercial cultivation in suitable areas and chances for marketing. Since all of them may not be acceptable for fresh consumption as table fruit, product diversification should be thoroughly evaluated to gain popularity for such plants. Practices and techniques employed for utilizing these fruits by local people where these plant species are seen at present can be scientifically and systematically refined for commercial exploitation.

Broad spectrum of agro climatic conditions and diversity in people’s preference for taste offer great chances to identify right fruit to a particular region for commercial cultivation in India. In this context, significance of under and un-utilized fruits for exploiting potentials become more clear. Identification of such plant species in different regions, extend and method of present utilization, nutritive value and pomological significance of the products, specific climatic and cultural requirements for successful growth and development should be documented as first step for exploitation of lesser known fruit species. Some of the under and un-exploited fruit species prevalent in tropical and subtropical conditions are discussed. In addition to this, attempt is made to incorporate an exhaustive list of plant species, which have potential for utilization as fruits and are rarely exploited at present. These are confined to only limited localities where people use produces for various purposes and are in most cases little known to other parts of world.

1.1 Forest Resources

Forest resources usually provide the raw materials for homes, workplaces, the books and newspapers, and the packaging that contains food and other products of our labor. Forest ecosystems supply our water, maintain our climate, and help purify the air, protect soils, and provide for wilderness experiences. Forests provide habitat for wildlife, and serve as preserves of biological diversity. Forests are sources of food, fuel and medicine for people all over the world. Forests shape the recreational landscape, help stabilize our farms, and enhance our cities.

About 30 per cent of the world’s total land areas are covered by forest with the area of 3.9 billion hectares. Nearly 47 percent of the world’s forests are in the tropics, 33 percent in the boreal zone, 11 percent in the temperate zones, and 9 percent in sub-tropical areas. The 94 million hectares of forest lost over the ten-year period, represented about 2 per cent of the world’s total forest cover, or an area larger than Venezuela. Two thirds of the world’s forests are located in ten countries: the Russian Federation, Brazil, Canada, the United States, China, Australia, the Democratic Republic of the Congo, Indonesia, Angola and Peru. Most of the deforestation work was performed in natural tropical forests, which lost 14.2 million hectares a year over the last decade. Africa and South America have suffered the most deforestation.

Africa was the region with the highest deforestation in the world, which lost 5.3 million hectares of forest per year in the 1990s. Forests are a major factor in the climate change issue. Forest ecosystems contain more than half of all terrestrial carbon, and account for about 80 per cent of the exchange of carbon between terrestrial ecosystems and the atmosphere. Deforestation in the 1980s may have accounted for a quarter of all human-induced carbon emissions, the second greatest emitter after fossil fuels. Forest plantations comprise 5 percent of the world’s forests. Asia has the largest area of plantations, accounting for 62 per cent of the world total. China accounts for 24 percent of that total and India, 18 per cent. Plantations supply about 35 percent of the world’s round wood. The area of forest plantations increased by an average of 3 to 4 million hectares per year during the 1990s. Half of this increase was the result of afforestation on land previously under non-forest land use, whereas the other half resulted from conversion of natural forest. There are reports that 12 percent of the world’s forests, or about 480 million hectares, are in protected areas.

4.1 Urban Issues

(i) Water Problem

The world’s population is increasingly found in the cities. Now a days, throughout the developing world, urbanization trends are gaining speed and are irreversible. From a technical standpoint, it is easier to provide water and sanitation services to people living closer together in urban settings than in dispersed rural communities. However, the costs of meeting the needs are much higher per capita, and are growing. The health risks posed by the lack of sanitation increase exponentially as densities increase and as people share drinking water and sanitation resources.

The urban environmental sanitation crisis in developing countries is taking a large health, economic, and environmental toll on all city residents. Willingness to pay for basic water and sanitation services is often high in peri- urban neighbourhoods, provided that services are appropriate, effective, and affordable. The use of a strategic sanitation approach should helps to build capacity within implementing agencies and enhances the ability of communities to make sustainable sanitation improvements.

(ii) Energy Problem

Energy is basic to development. Modern energy services are powerful engine of economic and social opportunity: no country has managed to develop much beyond a subsistence economy without ensuring at least minimum access to energy services for a broad section of its population. It is not surprising to find, therefore, that the billion who live in developing countries attach a high priority to energy services. On average, these people spend nearly 12% of their income on energy. At the same time, the provision of energy services especially through the combustion of fossil fuels and biomass can create adverse environmental effects. In rich countries, much attention is directed to the regional and global consequences of fuel combustion, because many of the local effects have been controlled at considerable expense over the past half- century. In developing countries, the local environmental problems associated with energy use remain matters of concern that are as, or even more, urgent than they were in industrialized countries 50 or 100 years ago. Further, it is the poor who suffer most severely from such problems, because it is they who are forced to rely upon the most inefficient and polluting sources of energy services for lack of access to better alternatives.

INTRODUCTION

Anatomy is the branch of biological science which deals with the form and structure of organisms. The word “Anatomy” is derived from Greek, means cutting apart (Ana –separate, tomy-cut).

The study with unaided eye is Gross Anatomy / Macroscopic anatomy while the study of finer details of structure with the aid of a Microscope is Histology / Microscopic Anatomy.

Introduction

Fermented foods are those foods which have been subjected to the action of microorganisms or enzymes that cause desirable biochemical changes and significant modification of the food (Campbell-Piatt, 1994). Fermented foods are usually produced using ingredients of plants or animals in combination with bacteria or fungi. The bacteria or fungi are either sourced from cultures maintained by humans or from the environment. The origins of fermented foods go back many thousands of years, with early evidence of the alcoholic fermentations of barley to beer and grapes to wine. Evidence suggests that fermented foods were consumed 7,000 years ago in Babylon (Battcock and Azam-Ali, 1998).Throughout the world, the fermented foods are used by the people. It plays a major role in the diet in many developing countries. Several traditional fermented foods are prepared in rural areas of many countries.

1.1 Background

The whole world is characterized by diverse cultures, different approaches to life, divergent outlooks and world views and dissimilar living conditions and environments. The people in it live with cultural, social, economic and educational dissimilarities, differences, inequalities, and goals. Despite the disparities in everything, the whole world is unified by Information, Communication and Technology through the global media culture, technocapitalism, and information revolution. Gone are the days when people confined themselves to their hearths, farms, educational institutions and places of work, managing their lives with basic minimum requirements and needs!
