Introduction

Problem soils are those that impede agricultural productivity owing to mineral stress, dryness, acidity, sodicity, waterlogging, etc. Vertisol, acid sulphate soils, saline-sodic soils, peat soil, and fine textured alluvial soils were the categories Beek et al., (1980) used to group the problematic soils. In addition to vast areas where deficiencies of zinc, phosphate, and iron, or excesses of iron, aluminium, and manganese limit rice yields, Ikehashi and Ponnamperuma (1978) observed that approximately 100 million hectares of land that are physiographical and climatically suitable for rice lie idle due to the soil toxicities caused by salt, alkali, acid, or organic matter. Problem soils can be broadly defined as those that have unfavourable conditions whether natural or artificially created that severely restrict the successful development of crops. Soil profiles with high groundwater levels and a less permeable argillic layer, degraded soils, sandy soils with low fertility, coastal soils that frequently flood, and laterites could all be categorised as problem soils. Without taking into account related soil functions, soil health is evaluated independently. It is also based on the f indings from a few soil tests for different criteria. 2015 has been recognized the International Year of Soils by the 68th UN General Assembly in recognition of the importance of soil health in all dimensions.

The capacity of soil to function as a vital living system, within ecosystem and land use boundaries, to sustain plant and animal production, maintain or 

enhance water and air quality, and promote plant and animal health (Doran and

Zeiss, 2000). A healthy soil may function is as follows:

• Sustain biological activity, diversity, and productivity

• Regulate, store of nutrients and cycle water and, decompose organic

matter

• Filtering and buffering, degrading, mineralizing, immobilizing, and

detoxifying organic and inorganic materials

• Inactivate toxic compounds, suppress pathogens, protect water quality,

and enhance catchment soil health.

6.1 Introduction

The World Health Organization (WHO) compiled a list of 20,000 medicinal plants used in different parts of the world. An estimated 15,000 medicinal plant species, forming about 21% of the total plant species used for medicinal purposes in the world, fall in the endangered category (Schippmann et al., 2006). In India, medicinal plant species used under different traditional systems to a large extent are still gathered and collected from the wild in from of roots, bark, wood, stem and even the whole plant causing severe destruction of their habitat, resulting in loss of species/populations and erosion of genetic diversity. The remaining few are cultivated as crop plants, but marginally because of lack of assured market and can be safely termed as commercially under utilized and are also under threat. Therefore, despite India being rich in plants species with medicinal properties, genetic diversity within the species and the associated traditional knowledge regarding their use, the lack of awareness regarding the loss of species and genetic diversity due to destructive harvesting from the wild and many other factors, such as infrastructure development, iintroduction of exotic species is causing depletion of genetic diversity or loss of indigenous MAPs.

25.1 Introduction

Farmers must be able to take appropriate decisions at appropriate time. Incorrect judgement and decisions will return in failure of execution of farm plan and in turn economic loss. The farm management decisions can be broadly categorised into two ways.

Host -Pathogen Interaction

Most often, plants become diseased when attacked by living (biotic) or affected by non-living (abiotic) pathogens.

In the first case, at least two components viz., host and pathogen must come into contact and interact for plant disease to occur.

Then, for disease to develop, a third factor, a favorable range of environmental conditions, must also occur.

The interaction of the three disease factors was often visualized as a triangle called the “Disease Triangle".

Each side of the triangle represents one of three components.

Enzymes, toxins, growth regulators, and polysaccharides are much more common and perhaps more important in the development of plant diseases. The pathogen produce these substances when grown on certain substrates (inducible). Let’s talk carefully one by one

Enzymes in plant diseases.

Toxins in plant diseases.

Growth regulator in plant diseases.

Polysaccharides in plant diseases.

Introduction: Indoor Air Pollution

People think that while they are indoors, they are breathing clean air. After all, pollution is found outside, and indoor air is filtered through the HVAC system.

Indoor air can have significantly higher concentrations of pollution than air found outside. Plenty of evidences exists. Global Burden of Disease Risk lists indoor air pollution as the ninth biggest health risk.

Commercial Building

Commercial buildings consist of government buildings, banks, hospitals, schools, malls, retail, restaurants, and office spaces. Among these, office and retail occupy the major percentage of energy consumption. 

More than 40% of the total final energy consumption and about 30% of greenhouse gas (GHG) emissions are in connection with the civil and residential sector.

Maximum energy consumption in commercial buildings by HVAC system (51% followed by appliances and food service equipment (20%), lighting(12%), electronics and information technology(9%) and water (8%).

Introduction

India has vast livestock resources. Livestock sector includes animal husbandry, dairy and fisheries sector. Livestock provides livelihood to two-third of rural community and employment to about 8.8 % of the population in India. Livestock sector contributes 4.11% GDP and 25.6% of total Agriculture GDP. It provides milk and milk products, meat and meat products, and also constitutes a major supplier of food and food articles, raw materials, and finished products.

A large number of arid and semi-arid fruit crops are used by the local inhabitants. These fruits are better known as protective food as cultivation is restricted and are grown mainly as wild. Being tolerant to biotic and abiotic stresses, these fruit crops are suitable for growing in drought prone areas. Semi-arid fruits are the oldest fruit tree crops with wide distribution, reflecting their adaptation to a wide range of edapho-climatic conditions. Development of viable agro-techniques, propagation methods, canopy management, and biotic and abiotic stresses management are equally important for improving productivity and quality of arid and semi-arid fruit crops.

Precision viticulture aims to optimize vineyard management, reduce use of resources, reduce environmental impact and maximize yield and quality of grapes. New technologies as UAVs, satellites, proximal sensors, variable rate machines (VRT) and robots are being developed and used more frequently in some parts of the world in recent years. Developments and abilities of computers, software and informatic systems to read, analyze, process and transfer a huge amount of data are major milestones in precision viticulture. In addition, different decision support systems (DSSs) for making better crop management decisions at the right time also assist vine growers.

Hydroponics is a technique of growing plants using mineral nutrient solutions with or without the use of an inert medium such as gravel, soil, vermiculite, rock wool, peat moss, saw dust, coir dust and coconut fibre-provide mechanical support. The term Hydroponics was derived from the Greek words ‘hydro’ means water and ‘ponos’ means labour and means water work. The word hydroponics was coined by Professor William Gericke in the early 1930s; describe the growing of plants with their roots suspended in water containing mineral nutrients. Researchers at Purdue University developed the nutriculture system in 1940. During 1960s and 70s, commercial hydroponics farms were developed in Arizona, Abu Dhabi, Belgium, California, Denmark, German, Holland, Iran, Italy, Japan, Russian Federation and other countries.

Introduction

Entomophagy, the consumption of insects, is rooted in human evolutionary history (Fontaneto, 2011). Throughout Africa, Europe, Asia, and Latin America, insects have held a vital position in the timeline of human nutrition. There exist more than 1900 documented species of insects that serve as human diets at globally, with notable groups encompassing grasshoppers (Orthoptera), caterpillars (Lepidoptera), grubs (Coleoptera), wringed termites (Isoptera), some hymenopteran insects, cicadas (Hemiptera), and a diverse array of aquatic insects. It is intriguing to observe that insects are regularly consumed by over two billion people, and in specific regions, they make up a substantial portion of the animal proteins consumed.

Introduction

The Greek term "Sericos" is the source of the English word "sericulture". The words "Seri" and "Cos" in this word both refer to culture. Sericulture is the art of rearing the silkworms for the purpose of producing silk. An elastic protein of insect origin, silk is synthesized by the silk gland of the silkworm. Fibrion and sericin, two various types of proteins, constitute the fiber known as silk. Silk is most frequently produced by chins. Following China, India is the second-largest producer of silk. Furthermore, it is the world's largest consumers of silk. The major silk producing state in India is Karnataka. Tasar, Muga, Mulberry, Oak tasar, and Eri silk are all produced in India. One other commercial fabric of animal origin outside wool is silk, which is a gift from nature to humans.

Introduction

"Research is the systematic approach to obtaining and confirming new and reliable knowledge." It is a systematic and orderly (following a series of steps). Purpose is new knowledge, which must be reliable. Thus research is:

1. Searching for explanation of events, phenomena, relationships and causes

• What, how and why things occur
• Are there interactions?

2. A process

• Planned and managed - to make the information generated credible
• The process is creative
• It is circular - always leads to more questions

Clinical complaints and observations should be kept in mind while interpreting the electrocardiogram.

Introduction

Since shrimp aquaculture became a big commercial enterprise in the 1970s, disease has had a significant influence on the industry. Major diseases of farmed shrimp have been identified as those caused by viruses, true bacteria, protozoa, and fungi. Nowadays, chemotherapeutics, regular sanitization, and enhanced culture procedures are employed to treat many bacterial, fungal, and protozoan-caused illnesses. Shrimp farming continues to be impacted by diseases, and their avoidance necessitates the development and use of a biosecurity policy unique to each facility, culture system, and sanitary zone.

Introduction

Food demand is rising at an unprecedented rate as the world's population continues to rise. Meeting this rising demand is a significant challenge that requires innovative and sustainable solutions. While traditional agriculture has long been the backbone of food production, alternative methods such as aquaculture have gained recognition for their vital contribution to global food security. The projected global population of over 9 billion by 2050 presents a significant challenge in meeting the nutritional demands of an ever-expanding populace. Seafood represents a crucial source of animal protein, essential nutrients, and omega-3 fatty acids, making it a dietary staple for millions of individuals globally, particularly in coastal regions and developing nations.

Introduction

Plants are the principal producers of phytochemicals, which are compounds with biological activity. Plants serve as the primary source of many active compounds in the pharmaceutical business. Their pharmacological character istics make them useful in the treatment of fungal and bacterial infections, as well as degenerative conditions such as diabetes and cancer that progress over time. Pharmacologically, it has specific effects on human health, including anti-inflammatory properties, antiallergic, antioxidant compounds, antimicrobial, antifungal, antispasmodic, chemopreventive, hepatic-protective, hypolipidemic, neuroprotective, hypotensive, antiaging, bone density loss, DNA damage, cancer, and heart diseases.

Introduction

In 1928, Alexander Fleming, a Scottish bacteriologist, made a significant observation while studying bacterial cultures. He noticed that colonies of bacteria on a culture plate had been negatively impacted by the presence of a mold called Penicillium notatum, which had accidentally contaminated the culture. Around a decade later, a team of researchers including British biochemist Ernst Chain and Australian pathologist Howard Florey successfully isolated the active compound responsible for this effect and named it penicillin (Lalchhandama, 2021).

Weeds have specific characters which helps them to adapt to any stressful situation and successfully, compete with the crop. They have survival strategies which help them to overcome vagaries of nature like extreme cold, heat, drought, biotic stresses and soil abnormalities. Their most important characteristic is the ability to succeed in any adverse situation even in disturbed soils. The age old war between man and weeds makes it pertinent to understand the characteristics of weeds which make them better competitors in the field.

Introduction

Planning is a “dynamic act of reflecting about, thinking about, and choosing among various options regarding the goals and objectives and the route to journey i.e. educational experience, we should follow to reach those destinations” (Forest and Baker, 1994). It offers opportunity to people to “participate” and “contribute” in the process. Therefore, it is understood that “planning extension programs has become an increasingly accepted practice among national authorities” (Maalouf, in Rivera, 1987, p. 116 as cited by Cristovao et al?, 1997).

“Activities which develop individual knowledge, talents, skills, and behaviour and improve institutional structures and processes so that the organization may efficiently accomplish its mission and goals in a sustainable manner” it refers as a capacity building. One of the crucial elements of capacity building is training.

Training for Development

Training is becoming an integral component of HRD. It has developed into one of the elements that allows any institution to produce its personnel who are the most productive and qualified.

1.1 Introduction

The greenhouse industry is rapidly growing, particularly in mild climates, and is crucial for providing access to fresh and clean food. Greenhouses provide an optimal climate for crops to grow and protect them from outside pests. Furthermore, greenhouse production has the potential to reduce water waste and implement integrated protection and production (IPP). It is essential to consider the environmental impact of protected cultivation, and Life Cycle Assessment (LCA) is a valuable tool for evaluating these impacts.

11.1 Introduction

Horticultural crops are grown by farmers with the aim of generating profit. For a business to prosper, it is crucial that its products are delivered to customers who are satisfied with their quality and value, and who will continue to purchase them. Therefore, growers must continually meet consumers’ demand for fresh greenhouse-grown items by utilizing all available technology and expertise in producing, harvesting, packaging, storing, transporting, and marketing their goods. The needs of the consumer should drive production.

12.1 Introduction

It is important to note that growing crops in a greenhouse requires a significant f inancial and administrative commitment. In order to ensure profitability, firms need to consider both cash flow and profitability. An enterprise budget can help address profitability potential by itemizing costs incurred across a typical production cycle. On the other hand, a cash flow budget is used to analyze the cash inflows and outflows of the enterprise over a fixed period of time.

Identify and Describe Program You Want to Evaluate

The first step in conducting a program evaluation is to clarify why we are doing it, what we want to achieve, and what we will focus on. This will help us to define the evaluation questions, criteria, indicators and methods that will guide our data collection and analysis.

What is Program Evaluation?

Concept of Environmental Impact Assessment Introduction, what it is, who does it, how it is done?

Environmental Impact assessment (EIA) is the estimation of the environmental consequences of a plan, policy, program, or actual projects prior to the decision to move forward with the proposed action.

Introduction to EIA

An EIA may be defined as: a formal process to predict the environmental consequences of human development activities and to plan appropriate techniques to eliminate or reduce adverse effects and to augment positive effects. to enhance positive effects.
