The large and diverse livestock resources of India benefit millions of people in rural areas, enhancing their standard of living. The key elements of sustainable agriculture are livestock resources. India has a population of 535.78 million livestock. According to 20th livestock census 2019,India ranks first in the world for the number of buffalo (109.85 million), second in number of cattle (192.49 million), third for the number of sheep (74.26 million), fifth for the number of chickens and ducks (851.81 million), and tenth for the number of camels (2.5 lakhs). About 8.8% of India’s population is engaged by the livestock industry, which provides a living for two-thirds of the country’s rural communities.

1.1 Perspective

From the very dawn of evolution of human beings, man has been using plants as food, for wellness and as medicine to alleviate diseases and discomfort. People living in different parts of the world, both new and old, in the centres of some of the oldest civilizations, had selected organisms from time immemorial for food and medicine by a process of trial and error or even by experimentation with the biological resources, particularly among the plants growing around them. These have been referred to as ethnic food/traditional food and ethnic medicine/traditional medicine. India is one of the mega centres of biodiversity, and that of the ethnic diversity, that evolved over millennia with settlement of diverse races coming from different regions of the world, besides the indigenous people. Thereby, it inhabits some of the most diverse cultural traditions. This process has led to further evolution of some of the oldest indigenous civilizations originated in the Indian Subcontinent with amalgamation of exotic traditions and the knowledge. Integration of the knowledge associated with the use of plants with medicinal properties has enriched its great heritage of medicinal plant use, the Ayurveda, i.e., the knowledge of life and longevity, dating back to the pre-historic and the early Vedic period.

1.1 General

Renewable technologies are considered to be clean sources of energy. The optimal use of these resources minimize environmental impacts, produce minimum secondary wastes, and are sustainable based on current and future economic and social needs. Sustainable development requires methods and tools to measure and compare human activities’ and its environmental impacts for various products. Renewable energy sources (RES), which include biomass, hydropower, geothermal, solar, wind, and marine energies, supply 14% of the world’s total energy demand. Renewable resources refer to primary, domestic, and clean or inexhaustible energy resources. Large-scale hydropower energy supplies 20 % of the global electricity need. Wind power in coastal and other windy regions is a promising source of energy.

Renewable energy resources can make a decisive contribution to the economic, social and sustainable development of rural regions in developing countries, yet the consumption of fossil fuels is dramatically increasing along with improvements in the quality of life, the industrialization of developing nations, and the increase of the world’s population. It has long been recognized that excessive consumption of fossil fuel leads not only to a diminishing fossil fuel reserves more quickly, but also has a significant adverse impact on the environment. Such impacts result in increased health risks and the threat of global climate change. Changes to improve environmental conditions are becoming more politically acceptable globally, especially in developed countries. Society is slowly moving towards seeking more sustainable production methods, minimizing waste, reducing air pollution from vehicles, generating distributed energy, conserving of native forests, and reducing greenhouse gas emissions. Increasing consumption of fossil fuel to meet out current energy demands, however, has sounded alarms over regarding potential energy crisis. This has generated a resurgence of interest in promoting renewable alternatives to meet the developing world’s growing energy needs. Excessive use of fossil fuels has caused global warming from carbon dioxide emissions, therefore, promoting renewable forms of clean energy is eagerly required. To monitor the level of these greenhouse gas emissions, an agreement that has fulfills the objectives of the Kyoto Protocol was create with overall pollution prevention targets.

Water is an important element for life on the earth. It is an essential recurrent natural resource for environmental sustenance, agricultural productivity, industrial growth, power production, enrichment and renewal of land and air. For easy assess to the water, the first human settlements occurred along the banks of rivers and ensuing civilizations flourished in river valleys. For example, the Indian civilization of Mohanjodaro and Harappa developed in the Indus valley, the Egyptian civilization in the Nile valley, the Chinese civilization in the Yangtze valley, the Babylonian civilization between the Tigris and the Euphrates rivers, Aztec, Maya and Incas civilization in the basin of Amazon river.

The industrial revolution, which, began in the early 18th century in some European and Asian countries, set in the motion for new forces in the society and greatly changed the pattern of social life on the earth. Rapid industrialization and urbanization subsequently brought many changes in the environment and ecosystems in the world. India also witnessed a phenomenon of industrial development in the post independent era. The last four to five decades have witnessed population explosion and increase in the per capita consumption of food, consumer goods and utilization of natural resources. These have lead to the proportionate increase in the domestic and industrial effluent generation in India. The water pollution is continuously increasing at an alarming rate in Europe and Asia. By the end of this century. India's Population is projected to double itself from its present level. Similarly the per capita consumption of food has been estimated to increase by 40% resulting in 50 % production of industrial and domestic effluents in near future.

Apart from the quantity, there will be qualitative changes in the effluent generation which are likely to contain greater amount of oil, toxic chemicals, detergents and dyes. A large number of these compounds are non-biodegradable and are cumulative, thus rendering toxic product. Certain group of animals and plants are selective in their functions and can executive certain toxic chemicals and heavy metals. These biomes are helping more effectively on recycling of industrial effluent as well as domestic effluent management system.

In nature, there exists a balance between abiotic and biotic communities like animals and plants population, raw materials and total biomass present at any time. This balance ensures natural recycling and optimum production in naturally balanced ecosystems. The plant growth is slow, but it ensures optimum utilization of waste products and a healthy environment. The increased population and its human desire to possess all comforts and pleasures had lead to over exploitation of natural resources. The high demand of natural resources lead to the beginning of waste accumulation due to the creation of man made imbalances in the environment. The environment is to provide up to date information about important concepts in surrounding. Information is presented from an analytical, observational and multidisciplinary perspective from which we must view environmental issues in order to the study successfully.

Insects are prevalent on this globe due to their varied adaptations and hence constitute the largest component of the animal kingdom. Only around 5 per cent of the total insect species, act as pests, rest either are beneficial like honey bees, lac insect, silk worms etc. or are harmless. Insect pests can be of medical, veterinary, house hold and agricultural importance, as these creatures harm our health, animals’ health, our belongings and also the agricultural health. Though all these components are equally important but, in this book, the last one i.e. agricultural health, have been taken into consideration. Insect pests cause around 20 per cent loss to our crops by directly or indirectly affecting the crops both quantitatively and qualitatively. The insects have different types of mouth parts which are used for sucking, biting and chewing, sponging and lapping, siphoning etc. for food required for their survival and the insects with sucking and biting, and chewing types of mouth parts cause much of the damage. The mites (Phylum Arthropoda) though do not belong to class Insecta but in some instances also are of economic importance as they cause economic damage to agricultural crops and produce.

Like many other beautiful plants, Bougainvillea has been chosen as the symbol of a host of countries, regions and municipalities. It is the National Flower of the Caribbean Nation of Granada and the United States territory of Guam. It is also the official flower of several counties in Taiwan and Malaysia. In the United States, Bougainvillea is the floral symbol of three California cities (Camarillo, Laguna Niguel and San Clemente).

1.1 Weather

Firstly, what is weather? Simply, the conditions in the atmosphere above the earth is called weather. It refers to the conditions such as wind, rain and temperature, prevailing at a particular location during periods of hours or days. We often ask “what’s the weather like today”? Any individual can answer to this question as it requires only a short term experience or say exposure to the atmosphere. The TV news forecasters predict weather each day and inform about the temperature, cloudiness, humidity, or possibility of storm in the next few days. Weather is localised, say, it’s a hot and cloudy weather in one part of the country and dry and windy on the other part.

1.1.1 What are the factors that influence weather?

Before we try to understand the factors that influence weather, we must understand what the components that describe a weather conditions are? Is it the rains, or the air temperature or both? The answer to this question is not so easy, and it’s a bit complicated. There are many components that constitute weather. Weather components include rain, cloud cover, sunshine, winds, hail, snow, sleet, storms, thunderstorms, heat waves and many more. These components are sometimes referred as weather parameters or climate elements. Each of these components define weather patterns of a particular area. These components determine the status of local atmospheric conditions. Again, as a basic definition, weather is the state of the atmosphere and majority of weather phenomena occur in the lowest layer of the atmosphere, called as the troposphere. Does it mean that ground conditions such as the topography, water bodies and vegetation of a particular area has nothing to do with it? No, it is not so. The state of the atmosphere is subjected to various processes taking place not only in the atmosphere but also in the ocean, the sea-ice, the vegetation, etc. Weather parameters or the components of weather form a sequence of events, and the influences are far reaching and they do not remain solely in the atmosphere. For example, terrestrial radiation impacts the air temperature, air pressure and humidity. The terrestrial location also influences the cloud formation. The clouds may or may not turn into precipitation depending on the outcome (cloud or rain), which is by and large governed by troposphere. Likewise, a lack of precipitation affects not only weather conditions, but also soil moisture conditions that may result in lowering of water levels (ground water table) in soil. Wind speed and direction are governed by the atmospheric pressure and air temperature. So, all these parameters or components are interrelated and the weather conditions are the outcome of their interactions. Therefore, we can say that, the three main components of weather are temperature, precipitation and solar radiation. These components are influenced by different factors.

Nutrition plays a vital role in the health, well-being and longevity of animals. The science behind nutrition encompasses the dietary needs of animals and how these needs are met through various forms of food/ feed, supplements and feed additives. A well-balanced diet is fundamental to the health of both domesticated and wild animals. Veterinary nutrition takes into account the physiology, biology and pathology of animals, aiming to optimize their health, performance and longevity through the right nutritional approaches. Proper nutritional management is crucial not only for growth and reproduction but also for disease prevention and recovery. Veterinary nutrition encompasses understanding metabolic and nutritional disorders, gastrointestinal disturbances, metabolic imbalances and systemic conditions. It focuses on providing animals with balanced diets to meet their physiological needs. The right blend of carbohydrates, proteins, fats, vitamins, and minerals supports growth, immune function and production. Deficiencies or excesses in nutrition can lead to disorders such as metabolic imbalances, gastrointestinal disturbances, and organ dysfunction. Understanding nutritional science enables veterinarians to address and prevent conditions like ketosis, fatty liver, and etabolic acidosis. Veterinary nutrition and the understanding of associated metabolic and systemic disorders are essential for ensuring animal health and productivity. From preventing nutritional deficiencies to managing complex metabolic conditions, veterinarians play a critical role in maintaining the wellbeing of animals and poultry. By addressing these challenges through research, innovation, and education, we can ensure sustainable animal husbandry and improved welfare.

Plant absorbs large number of elements from the soil and other sources during their growth and development. But all these elements are not essential for plant growth. Seventeen mineral elements are known to be essential for the growth and development of all plants. A list of essential nutrients, their source and forms by which they are absorbed by plants are presented in Table 1.1.

Except carbon (C), hydrogen (H) and oxygen (O), all the other nutrients are obtained by plants largely from soils, fertilizers or manures. It has been seen that the number of nutrients obtained from soil is about 5 times the number of nutrients obtained from air and water. However, most of the plant tissue, in general, from 74 to 99.5% is made up of C, H and O i.e. nutrients obtained from air and water and only 0.5 to 26% of the plant tissue is synthesized from soil constituents. In ordinary (normal) conditions of agriculture, except drought, C, O and H are not limited for plant growth. It is the remaining 14 elements from soil that are usually limiting plant development and hence considerable emphasis is placed on the improvement of soil in respect of greater availability of these 14 nutrients. It may be borne in mind that all nutrients are essential for all crops even though their requirements differ from crop to crop and even among varieties of a given crop. Secondly, all nutrients are equally essential regardless of amounts required. For example, to produce one tonne of grain, wheat may absorb 25, 9, 33, 3.7, 5.3 and 4.7 kg of nitrogen (N), phosphorus (P), potassium (K), sulphur (S), calcium (Ca) and magnesium (Mg), respectively and 56, 624, 70, 24, 48 and 2 g of zinc (Zn), iron (Fe), manganese (Mn), copper (Cu), boron (B) and molybdenum (Mo), respectively. If the crop (any crop) does not get the smallest amounts of micronutrients needed, it cannot make the best use of abundant NPK.

According to Liebig’s Law of minimum which he enunciated in 1855, the growth of a plant is limited by that nutrient which is in shortest supply. This law in fact lays the ground rules for balanced crop nutrition.

1. FOOD AND ITS SIGNIFICANCE

Food is the basic necessity of all the living world and the man is no exception to this. The basic purpose of food is to provide energy for the routine body functions and protect the body from various diseases. Life cannot be sustained without adequate nourishment for a healthy and active life, diets should therefore, be planned and consumed on sound nutritional principles (Fig. 1). For want of nutritious foods, consequence is the prevalence of malnutrition. There are several diseases that are related with deficiency of nutrition food, if not consumed. Such diseases include Kwashiorkor that can develop in children consuming insufficient protein even if total calories are sufficient. Marasmus is often due to the cessation of breast feeding and the attempt to replace it with foods, inadequate in protein such as rice broth. Other nutritional diseases still found particularly in the developing world are childhood blindness (vitamin A deficiency), rickets (vitamin D deficiency), beri-beri and infantile beri-beri (inadequate thiamin intake), pellagra (inadequate niacin intake), anemia (iron deficiency), goiter (iodine deficiency), etc. To cope up with this, the diet needs to be supplemented with nutritious food components including fruits and vegetables to make it more suitable for the growth and development of body.

Out of different types of foods, the fruits and vegetables constitute an important component of the food. Horticultural crops occupy a prominent position both in the importance and production in the world. The temperate fruits and vegetables are an important part of the horticultural crops, in terms of production and role in human health. These crops assume all the more importance due to their antioxidant activity, and presence of minerals and vitamins. Both fresh and processed fruits and vegetable, their different products are consumed. They are also called as protective foods. Fruits and vegetables are major sources of important vitamins like B and C and minerals such as Ca, Fe, P and K.

The North Eastern region of India is a gift of nature having rich cultural heritage and biodiversity reigning under diversified agro-climatic conditions. The region, which is only 7.76 percent of the geographic area of the country, accounts for 25.11 percent of its forest cover (Forest Survey of India, 2008). For its richness in biodiversity, the region has been identified as one of the 18 biodiversity hot spots of the world. The region is inhabited by many important tribes, which are about 27 percent of the population of the region. An important feature of the land use in the region is prevalence of shifting cultivation, locally called jhum, in almost all the states. Shifting cultivation or slash and burn agriculture is the main form of agriculture. It involves clearing of vegetation and then slashing and burning the plant parts including debris. Shifting cultivation, beside an agricultural practice, is also an integral part of their ethno-cultural life style. With the rising population, the cycle of shifting cultivation has reduced to less than 5 years, resulting in degradation of forest in these areas. After 2-3 years of cropping, the land loses its fertility and farmers shift to another piece of forested land for cultivation.
The Himalaya and adjacent hill ranges in the North East present a complex array of physical and geo-political environment, well known for geo-hydrological, biological, aesthetic and cultural values. Although the main Himalaya and the hills of North East have a number of similarities in their physiography and ecology, they differ inherently in terms of origin and evolution. The former ranges, geologically young and tectonically active, were formed as a result of massive collision between Eurasia and the north ward drifting Indian plate, nearly 40 million years ago. As the Indian plate is still moving northward, the Himalayan ranges continue to be pushed upwards at the rate of about 5cm/ year.
Agriculture and animal husbandry have been an age old traditional land use practices practices in the Indian Himalayan Region. Traditional millets, cereals, pulses along with horticulture crops are grown in many areas. In Himachal Pradesh, with good network of roads, horticultural crops have been a major source of revenue. It is established that at least seven units of forest are needed to sustain one unit of agriculture in the mountains.

1.1 Background

The aftermath of Green Revolution has contributed to both coercions and pollution, albeit, it saved human civilization from hunger, malnutrition and impoverishment. The beginning of GR era, with the prevailing objective and condition, has got less but few choices to go for intensive cultivation that invited chemical fertilizer, assured irrigation and farm mechanizations to make the 'magic gene' revolutionizing the production, productivity and livelihood security in agriculture as well.

The welcome of exotic genes into Indian agriculture has also triggered the silent oftraditional cultivars. Nevertheless, the quantum jump of an agriculture with a production of 55 million tons to 120 million tons during 70s, has contributed to make India self-reliant in food and we have been able to earn a new esteem in the global geo-political scenario by throwing away the 'begging bowl' called PL480.

Aristotle (384 to 322 BC), an ancient Greek philosopher and scientist (Fig. 1.1) developed the concept of meteorology as a study of the lower atmosphere. Over the years meteorology developed as a science of atmosphere which deals with the physics, dynamics and chemistry of the atmosphere and their effect upon the earth’s surface, oceans and thereby life in general either directly or indirectly.

As the atmospheric conditions change from time to time in a given area and from place to place in a given time, climatology was developed as a science which studies the average conditions of the weather and its variability over a long period of time.

All most all the human activities are greatly influenced by the weather and climate to a greater extent. Therefore, the scope of meteorology encompasses various activities which are of considerable economic significance as detailed here below;

1.1 Housing

The design and construction of houses, buildings, industrial structures etc. depends upon the weather and climate of the region. Orientation of doors, windows roofs of the buildings are usually designed to provide maximum comfort and convenience to the people.

Insects are the most successful arthropods in animal kingdom. They are found in almost all habitats on earth except for the frozen polar environments at the highest altitudes and in the immediate vicinity of active volcanoes. They are the only invertebrate animal (animals without backbones) with wings. The success of insects on the planet is due to their ability to fly and rapidly colonize new habitats. The study of insects is called entomology and entomologists are those scientists who study about insects.

India is an agriculture based country which is one of the few developing countries in the world. It successfully achieved Green Revolution during the late 1960s (1967-68). At present, agriculture is a principal means of livelihood for over 58.4 per cent of Indiaís population directly or indirectly (Anonymous, 2011). It is worthwhile to mention that although agriculture continued to be the mainstay of the Indian economy previously (Anonymous, 2010b) yet now its share in the Indian economy is declining year after year (Anonymous 2013d). After Independence, agricultureís sector contribution to GDP swings between 50-60 per cent. Even in 1950-51, it was 55.1 per cent, but fell to mere 17-18 per cent in 2008-09 (Mahajan and Gupta, 2009).

1.1. History and Origins of Rabbits

The existence of rabbit with human being remained from time immemorial. Romans were the first to domesticate wild rabbits in the 5th century by the monks of the Champagne region in France as a readily available food source. Rabbits were introduced to Britain during the 12th Century, and during the Middle Ages, the breeding and farming of rabbits for meat and fur became widespread throughout Europe. Sources suggest that some women among the Medieval gentry even kept rabbits as pets. The selective breeding of European rabbits meant that distinct breeds arose in different regions, and the origins of many old breeds can be traced back several centuries.

1.0 Overview

Natural resources sustain life and are critical for economic development of nations. In developing countries like India where more than half the population is rural, economic development is inextricably linked with agricultural development. In these countries, the food and livelihoods security of the poor are critically associated with access to the services provided by the natural resources - land, soil, water, biodiversity and climate resources. The natural resources are finite, and with increasing population, economic growth, urbanization, and demands for food and other agricultural commodities, these are being increasingly strained. As a result, the productive capacity of the natural resource base is shrinking and deteriorating. Sustaining the productive capacity of natural resources for future generations, while meeting the food and other demands of the growing populations, is the major development challenge of the twenty first century.

In India, during the last forty years the net sown area under agriculture has remained nearly constant at 141 million ha. In the same period, the population has more than doubled (from 541 million in 1970 to 1186 million in 2010) and per capita income grew by more than 3.5 times (from Rs 14824 in 1970 to Rs 53331 in 2010). As available land resources for agriculture are finite, increases in agricultural production to meet the growing demands of the population have to come from intensification of agriculture on the same lands. As a result, the quality of soils on these lands is gradually deteriorating both at the farm and ecosystem levels. The major threats to soil quality come from loss of organic carbon, erosion, nutrient imbalance, compaction, salinization, water-logging, decline in soil bio-diversity, urbanization, and contamination with heavy metals. More than 100 million ha of the total cultivated land of 141 million ha is stated to be under some form of soil degradation.

Similarly, utilizable fresh water resources of India are finite at about 1123 billion cubic meters (BSM), of which about 690 BCM are from surface water resources and 433 BCM are from groundwater. This supply is shared among multiple uses: human and animal consumption, agriculture, urban uses, industry and for provision of environmental services. The total water demand in 2010 is estimated at 710 BCM and is projected to increase to 1180 BCM by 2050. Several parts of India are already facing severe water shortages as a result of the growing demand for water. The quality of water resources is also impacted by agricultural intensification and development, and is increasingly a matter of concern. By the year 2050, when population is expected to stabilize, the shortages will only intensify. The country as whole can be on the verge of becoming a water scarce country, with nearly all the presently estimated utilizable water resources being put to use.

Biodiversity natural resources refer to the abundance of different species and ecosystems in nature. These resources are the primary sources of present and future productive agriculture and human well being, as they provide the basic resources for use in breeding crops and livestock, soil formation and structure, soil fertility, nutrient cycling and the provision of water services. India is among the 12 mega diversity regions of the world. It is known to have more than 18,000 species of higher plants including, 160 major and minor crop species and 325 of their wild relatives. Increasing pressure from human population growth, agricultural intensification, urbanization, pollution and degradation of land, soil and water resources are having a negative impact on the plant, animal and microbial biodiversity resources of the country and their productivity.

The concern for nature and the focuss for all things which are basic and natural has been spearheading to a green movement of everything natural and nature-based consumer products all over the world. God has given diseases and remidies also in the nature only we have to properly find out. In today’s world of consumer boom, the role of essential oils has increased many folds. Uptil now known applications of essential oils, more and more areas are opening up which will benefit the industry. Use of essential oils in therapeutics is becoming popular in India, China, Japan and European countries. Aromatherapy involves the use of essential oils and aromatics derived from plants to cure diseases. These plants are known as aromatic plants. Aromatic plants possess odorous volatile substances which occur as essential oil, gum exudate, balsam and oleoresin in one or more parts, namely, root, wood, bark, stem, foliage, flower and fruit. The characteristic aroma is due to a variety of complex chemical compounds. The term essential oil is concomitant to fragrance or perfumes because these fragrances are oily in nature and they represent the essence or the active constituents of the plants. They are called volatile or ethereal oils as they evaporate when exposed to air at ordinary temperatures. Essential oils are highly concentrated, low volume, high value products.

Newer technologies involve fermentation by specific strains of lactic acid bacteria which bring specific fermentation under controlled conditions to a specific fermented product with enhanced organoleptic, nutritional and therapeutic qualities. Today health is of primary concern. It is important to have nutritionally balanced food with good bacteria. For this, probiotic foods top the list. The functional food concept was initially developed in Japan in 1990‘s as there were many side effects of allopathic medicines. A regulatory system has been initiated by the ministry of health and welfare to approve certain foods to improve health. These are now recognized as Foods for specialized health use (FOSHU). According to American dietic association (ADA) these foods are potential healthful food or food ingredients that may provide health benefits beyond the traditional nutrients. Probiotics are beneficial microorganisms. Probiotic foods as yogurt and sauerkraut are very well known. Fermentation increases the nutrient content and taste with the shelf life.
