Introduction

Aquaculture resources in India is vast in the form of ponds and tanks of 2.35 million ha, reservoirs of 3.15 million ha, oxbow lakes and derelict waters of 1.3 million ha and brakishwaters of 1.24 million ha. At present, the total fish production is 6.4 mmt. Out of which inland fish production is 3.4 mmt. The total aquaculture production of 2.47 million tonnes that constitutes 4.2% of global production was valued at US$ 2.9 billion (FAO, 2006). Ponds and tanks are the prime resources for aquaculture, however only about 0.8 – 0.9 million ha is used for aquaculture currently. Recently, National Fisheries Development Board with huge budget provision has been established to improve production, processing, storage, distribution and marketing of fisheries products (Anon, 2006 a, 2006 b). During 10^th and 11^th plan periods higher fish production targets have been kept evisiging a growth of about 8 percent from inland sector.

Phlox is a perennial and annual flowering plant belongs to family Polemoniaceae. “Phlox” is a Greek word meaning “flame” and was most likely named thusly due to its bright and vivid colours. Phlox originally came from North America and was available in England by the early 1800s. It quickly grew in popularity and today it is still found growing wild in gardens across the world. Among perennials, Phlox paniculata, Phlox divariecata, Phlox glaberrima are earliest species to be cultivated and reached to England and France from Virginia (USA) in the early 18^th century. Among annuals, Phlox drummondii is commonly grown in India. Annual phlox is propagated by seeds, whereas, cutting is used as propagating material for perennial species. Phlox is grown in the garden as bedding and border plant for its dramatic, fragrant, showy and long blooming flowers. The colour range includes white, rose, pink, purple, lavender, violet, pale blue, bright red and magenta. Some flowers are bicoloured.

ORIGIN AND DISTRIBUTION

Phlox is native to North America except one species i.e. Phlox sibirica which originated from Siberia (Meyer, 1944). They are found mostly in North America in diverse habitats from alpine Tundra to open woodland and prairie. Some flower in spring, others in summer and fall. Many are fragrant.

The diversity of species and genera is particularly high in California, USA, where 17 genera and over 170 species occur. Significant diversity also exists elsewhere in the world. A principle lineage consisting of Cantua, Cobaea, and Bonplandia is distributed natively only in Mexico, central America and northwestern South America. In Eastern North America, the genus Phlox is unusually diverse compared to the rest of the family. Other than members of Phlox, only a few species occur natively east of the Mississippi river in the United States, such as Ipomopsis rubra, Collomia linearis and a few Polemonium. A few Phlox and Polemonium species are also found natively in Eurasia. Central and South America, particularly the western regions of South America, are also home to some members of the phlox family. A small number of species from several genera that are most abundant in North America, such as Collomia, Gilia, Navarretia and Leptosiphon are found only in western South America, indicating multiple instances of long distance dispersal (Grant, 1959 and Morrell et al., 2000). Occasional species, such as skunkweed (Navarretia squarrosa) and Collomia grandiflora, have become weedy in parts of Europe and Australia and some cultivated species, such as members of Cobaea, have become naturalized outside their native range (Grant, 1959, Hussey et al., 1997, Pysek et al., 2002 and Anon., 2003).

This chapter documents shoreline changes of the Dakshina Kannada and Udupi districts of Karnataka State for the period between 1967 and 2005 studied by comparing the SOI topographic maps with IRS-1C/1D LISS-III satellite imageries through GIS techniques. Examination of coastal geomorphology, sediment flux and effectiveness of seawalls had indicated that the 130km long coastline of Dakshina Kannada and Udupi districts is essentially stable, but for seasonal variations. It has been estimated that, out of 130km, about 55km long coast is vulnerable to sea erosion, of which, 25km is covered byseawalls and covering another 10km length underway. It is revealed through field examination that protection of coastline through these measures is satisfactory only along few patches while other stretches of seawalls simply shift the zone of erosion to adjacent coastline owing to many reasons including quality of construction, unscientific positioning of seawalls, etc. It is also inferred that same is the case of many other coastlines elsewhere including Kerala coast. These experiences warrant scientific design and implementation of coastline protection measures.

INTRODUCTION

The 130km long coastal zone of Dakshina Kannada and Udupi districts is one of the densely populated coastal zones of India. The coastline is almost straight, regular and oriented towards N22°W, N12°W and N6°W directions at south of Mangalore, north of Mangalore and north of Malpe respectively. Barrier beaches and spits, ancient beach ridges, marshes, swamps and tidal flats characterize this zone. Natural features and man-made structures interrupt the shoreline. The natural features include estuarine mouths of Netravati-Gurpur rivers near Mangalore, Mulki-Pavanje rivers near Mulki, Udyavara river near Malpe, Sita-Swarna rivers near Barkur, Kollur-Chakra-Haladi rivers near Kundapur and rock exposures near Someshwar, Surathkal, Mulur, Kapu and north of Malpe (Fig. 1). The man-made structures include one major and four minor ports; breakwaters at the Netravati-Gurpur estuary, New Mangalore Port and Malpe harbor and a number of seawalls placed at various places along the coastline (Fig. 2). All these structures/features bring about local irregularity and contribute to erosion and accretion along the shoreline to some extent. Apart from these, source of beach material, coastal processes like wave refraction, longshore current, littoral drift etc.

ntroduction

The marketing systems and post-harvest marketing infrastructure have not been able to keep pace with the growing production and marketable surplus. This has brought to the fore, the need for providing farmers with access to competitive markets with adequate infrastructure including cold chain logistics, to enable them to realise better prices on the one hand and providing nutritious food to consumers at stable and affordable prices on the other. With this objective in view, the Government of India on 13th November, 2013 approved the proposal of Department of Agriculture & Cooperation for continuation and integration of ongoing Central Sector Schemes as Integrated Scheme for Agricultural Marketing (ISAM) during the XII Plan (2012-2017). The ISAM have the following five sub schemes: (i) Agricultural Marketing Infrastructure (AMI) [the existing schemes of Grameen Bhandaran Yojana (GBY) and Development/Strengthening of Agricultural Marketing Infrastructure, Grading and Standardization (AMIGS) will be merged as AMI] (ii) Marketing Research and Information Network (MRIN) (iii) Strengthening of Agmark Grading Facilities (SAGF), (iv) 

Introduction

Organic farming in floriculture represents a transformative shift towards sustainable and environmentally responsible agricultural practices, responding to the increasing demand for eco-friendly products worldwide. As awareness of the detrimental impacts of chemical pesticides, synthetic fertilizers and monoculture farming grows, consumers and producers alike are increasingly embracing organic methods. This transition is not merely a trend but a necessary evolution towards preserving ecological balance, promoting biodiversity and ensuring the long-term health of both human populations and the planet.The organic farming in floriculture is expansive, encompassing a holistic approach that integrates ecological principles into every aspect of f lower cultivation. Organic floriculture avoids synthetic chemicals, opting instead for natural alternatives that foster healthy soil, robust plant growth and resilient ecosystems. Key practices included in organic farming are crop rotation, green manuring, composting and biological pest control, all of which contribute to maintaining soil fertility and preventing pest outbreaks without harming the environment. These practices help create a self-sustaining system where natural processes regulate plant health, reducing the need for external inputs and enhancing the resilience of the agro-ecosystem.

Fats are obtained from both animal and vegetable sources. The principal animal fats are cream, butter, egg yolk, the fat of beef, mutton, pork, bone marrow, chicken fat, and codliver oil. Vegetable fats are those derived from fruits and seeds of plant, as olive oil, cottonsed oil, corn oil, peanut oil, soyabean oil and nut oils.

COMPOSITION AND NUTRITIVE VALUE OF FATS

Fats and oils, the most concentrated of fuel foods, were the first of the organic compounds or foods to have their composition determined. They are made up of same three elements which go to produce the carbohydrates, but the oxygen is less in proportion to the carbon. This explains the fact that fat yields more energy per gram than carbohydrates do.

1. INTRODUCTION

Landscaping is a branch of ornamental horticulture having aesthetic and beautifying value which freshens up the atmosphere, enhances the look of the environment and improves beauty of land. In the area of landscaping, it is beneficial to know about ground covers (grasses etc), hedging plants, and focus plants that will complement one another.

A garden by definition is a piece of land devoted to growing flowers, fruits, vegetables, shrubbery and turf. Gardens brighten their surroundings and they add to the beauty of the landscape. The types of flowers that can be grown in a garden depend on the size of the garden, its location and the amount of sunshine and shade it gets.

The occurrence of periods of water deficit for crop production, referred to as climatic drought, is commonly observed and leads to low water availability for crops. Besides climatic drought, crop water stress may also result from low levels of plant available water in the soil profile due either to the existence of physical barriers to water infiltration (e.g., surface sealing) or to soil chemical or physical limitations to plant root growth and root water uptake. Drought resulting from such factors will be referred to as edaphic drought since it is caused by soil specific conditions rather than by limited rainwater supply, and can occur even under conditions of sufficient and well-distributed rainfall. Finally, even where water is very scarce, particularly in the driest areas, a surprisingly small proportion of the available water is actually transpired by the crop. Non-productive losses include surface runoff, deep drainage, evaporation from the soil surface and deep cracks, and transpiration by weeds. Dry land farming is a system of crop cultivation depending on rainfall as the only source of moisture and the technologies refers to the cropping pattern/ rotation and agronomic practices adjusted and adopted in accordance with the moisture regime. The crops selected should have short duration, deep root system, erect leaves, moderate tillering and photosynthetically efficient.

7.1. BioNET International

7.1.1. What is BioNet International

BioNET-International, is the Global Network for Taxonomy, and is dedicated to creating sustainable mechanisms to assist developing countries to overcome the Taxonomic Impediment by becoming self-reliant in taxonomy i.e. self-reliant in the skills, infrastructure (collections etc.) and technologies needed to discover, identify, name and classify and to understand the relationships of all organisms on this planet.

It is concerned with helping developing countries to recognise and know the organisms that constitute and threaten their biodiversity, not for taxonomy’s own sake, but rather to support national programmes for sustainable agricultural development, and conservation and sustainable use of the environment.

BioNET-International is particularly focused on helping countries implement the various environmental conventions such as the International Plant Protection Convention (IPPC; www.ippc.int) and the Convention on Biological Diversity (CBD; www.biodiv.org), especially its taxonomic capacity building compnent, the Global Taxonomy Initiative (GTI). The subregional networks of BioNET-International have been identified as appropriate structures through which much of the GTI (www.biodiv.org/programmes/cross-cutting/taxonomy/default.asp) can be effectively implemented.

Definition

Public speaking is the process and act of speaking or giving a lecture to a group of people in a structured, deliberate manner intended to inform, influence, or entertain a listening audience. Public speaking is commonly understood as face-to-face speaking between individuals and an audience for the purpose of communication. It is closely allied to “presenting”, although the latter is more often associated with commercial activity. Most of the time, public speaking is to persuade the audience.

Public speaking can serve the purpose of transmitting information, telling a story, motivating people to act or some combination of those. This type of speech is deliberately structured with three general purposes: to inform, to persuade and to entertain. Knowing when public speaking is most effective and how it is done properly is a key part in understanding the importance of it.

Introduction

“Quality” refers to the aesthetic appearance and freshness of fish. It also involves safety aspects such as being free from harmful bacteria, parasites or chemicals. The best quality fish is the one consumed within the first few hours after postmortem. We studied in our previous chapters that in some instances, even very fresh fish in rigor mortis are unsuitable for filleting. So, slightly older fish in post-rigor are more desirable for the processors.

The assessment methods of fish quality are divided into sensory, instrumental, chemical and microbiological. Sensory method is superior and all other methods must correlate with the results of sensory evaluation. So, sensory method must be done more scientifically under controlled conditions without the effects of test environment, personal bias, etc.

4.1. Sensory Methods

Sensory evaluation is defined as the scientific discipline used to evoke, measure, analyze and interpret reactions characteristics of fish, as perceived through the senses of sight, smell, taste, touch and hearing. There are few instruments capable of measuring sensory profile viz. Instron for texture, electronic nose for odour, microscopic imaging for structure, etc.

In sensory evaluation, appearance, odour, flavour and texture of fish are evaluated by the human senses. The process involves three steps: (1) detection of a stimulus by the human sense organs, (2) evaluation and interpretation by a mental process; and (3) the response of the assessor to the stimuli. The response of stimuli varies among individuals e.g. some people cannot taste rancid flavour and some have low response to cold-storage flavour.

24.1 Introduction

Taxonomy, which includes identification and classification has transformed into systematics and biosystematics in the recent times and is integrating itself into the biodiversity, which is now a global phenomenon occupying the main thrust of human life (Narendran, 2001). The magnitude and cause of this biodiversity is the central problem of taxonomy and one of the key problems of science as a whole, not to speak of pest management. The science of taxonomy started in the late eighteenth century by a Swedish biologist, Carl Linnaeus who with a small number of similar minded scientists pioneered a standard system of using two Latin names for an organism, denoting “genus” and “species” which is still in vogue. This led to referring of biological organisms by an universally agreed name and identity, and further providing means for their realistic classifications. When these identifications and classifications got strengthened further with accumulated biological knowledge, it allowed the development of modern biology on a sustainable and stable base.

Introduction

Floral arrangement is the art of selecting and organizing flowers and foliage according to the elements and principles of design in order to attain a pleasing and interesting design. Arranging flowers is an artistic activity and a way to express oneself creatively.

21.1 Flowers and Foliage

Successful floral arrangement begins with plant materials that have been properly handled and prepared. Beauty and good composition of an arrangement is not determined by the cost or rarity of plant materials used, but by the way they are selected, cared for and arranged. The plant material has to be handled carefully, handling only the stems. Properly dried, bleached and dyed flowers, foliage and accessories can be arranged following the principles for dry flower arrangement.

Abstract

Plant architecture, plays a crucial role in gathering multiple resources from the environment. As a plant grows, they change its architecture with the surrounding environment for altering available resources. The architecture of the plant is modified through the distribution of assimilate, which conclude the growth rates of different organs. Plant roots expand to acquire soil water and nutrients (e.g. nitrogen, phosphorus) from different soil layers by adjusting their direction in order to growth which transported and allocated to whole plant for maintenance and expansion of plant organs. All plants gradually develop their architecture according to source–sink activities and endogenous signals. This adaptation can result in complex structures. This chapter deals with the importance, different method for changing the architecture   of vegetable crops for improving their yield and quality.

Introduction

The world does not function without mathematics. In our day-today life we come across many problems which are solved mathematically. The mathematical logical system follows “Yes” or “No”, “True” or “False”, “1” or “0” which are precise outputs for the precise inputs. There are several ambiguous or vague problems which cannot be given with accurate precise value with the conventional logical operators. Beyond this Boolean logic operator the logical system which mimics the human brain and gives precise solutions for the imprecise linguistic variables is the Fuzzy logic system. Fuzzy logic is a novel approach that intends to imitate human reasoning using calculations and operations with fuzzy systems and linguistic variables. The problems with vague imprecise data which we come across in our day today life cannot be solved by conventional binary logical method. The fuzzy logic solution spontaneously splits a complex problem into its component parts. This reduces the solution to its component parts. Compilers may re-assemble the code for effective execution on some target, but at the programmer level the problem is a number of simple tasks.

Fuzzy sets theory was introduced by Zadehin the year 1965, and it allows uncertain phenomena to be treated mathematically.

Dry Flower Products

Dry flowers are aesthetically beautiful and they enhance the décor and liveliness of any room. They bring the fiery warmth and bounty of the season into the home with ease every fall. Much of fall’s beauty lies in the glorious changing colors of autumn leaves. These flowers are dried to use them in a wide range of products. Dried floral products are widely used for decoration and for adding zest to a room. Apart from that they are also used as an essential component of many products. They are widely used to make handmade paper, lampshades, candle holders, jute bags, photo frames, boxes, books, wall quilts, topiary, cards and several gifts. The use of dry flowers in the making of these products enhances the appearance and beauty of these products. They look sophisticated when gifted to someone or used as a décor of your own home.

Accent : It is created in the garden to avoid the monotonous view. Mostly unusual objects like tall fountain, tree, statue etc are used to create the effect.

Acre: A unit of measurement of land area equivalent to 4000 sq.met or 0.4047 hectare.

Acrylic: It is a glassy thermoplastic that is incorporated in rigid plastic to enhance wither ability.

Aging: Refers to the processes acquiring maturity with the passage of time or normally an increment of time, which may or may not be accompanied by physiological changes including senescence. Aging thus includes a much ‘wider span’ of physiological processes, which may either “weaken the organism or to be neutral”.

Agmark: It is Agriculture Produce, Grading & Marketing Act, 1937 & voluntary in nature.

Anaerobic respiration: An incomplete oxidation of food to release partial energy takes place in the absence of atmospheric oxygen and occurs in cytoplasm.

Analytical chemistry: Deals with detection and estimation of elements and compounds.

The prosperity of any country depends upon the prosperity of its people. Food, clothing, shelter, health, education, security, roads, electricity and drinking water are the today’s basic needs. Farmers produce food. About 70 % of Indian population is engaged in farming. Therefore, prosperity of India would depend upon the prosperity of its farmers. This in turn depends upon the adoption of improved technology and judicious allocation of resources (land, labour, capital, machinery etc). Human race depends more on farm products for their existence than anything else since food and clothing – the prime necessaries are products of farming. Even for industrial prosperity, farming forms the basic raw material. To sustain and satisfy as many as his needs, the farmers include crop production, livestock, poultry, fisheries, beekeeping etc. in their farms. Earlier subsistence was the important objective of farming. Farmers took many activities such as planting of fruit trees in their farms or on the common lands just for the welfare of mankind without expecting anything in return. The kind of farming where subsistence and welfare of mankind were the main objectives is designated as mixed farming. Farming today is also a mix of enterprises. However, higher profitability without altering ecological balance is important in farming. A set of agricultural activities organized while preserving land productivity, environmental quality and maintaining desirable level of biological diversity and ecological stability is designated as “Farming System”. Here the emphasis is mainly on a system rather than on gross output.

In other words “farming system” is a resource management strategy to achieve economic and sustain agricultural production to meet diverse requirement of the farm household while preserving the resource base and maintaining high environmental quality. The farming system in its real sense will help to lift the economy of agriculture and standard of living of the farmers.
