INTRODUCTION

Coral reefs are fragile and most diverse and valuable ecosystems on earth. The stony corals are formed from the tiny, soft colonial organisms called polyps. They provide enormous ecological, economic services, and cultural value to hundreds of millions of people. They are significantly contributing to the nutrition, economic security and protection from natural disasters. They are often termed as the rain forests of the sea.

Coral reefs were first appeared 485 million years ago during the early Ordovician period. They belong to the class Anthozoa of animal phylum Cnidaria, which includes sea anemones and jelly fish. Coral reef is an under water ecosystem which is characterized by reef-building corals. Unlike sea anemones, colonies of coral polyps secrete a hard exoskeletons called reef which is made up of calcium carbonate to support and protect the corals. These reefs grow best in warm, shallow, clear, sunny and agitated water.

BIODIVERSITY

The term biodiversity was coined by Walter G. Rosen in the year 1985. Biodiversity refers to the variation among living organisms that can be found in a particular area such as terrestrial, marine and desert ecosystems and the ecological complexes to which they are a part. The study of biodiversity helps to understand the ecological stability, economic and ethical importance. Coral reefs are believed to have the highest biodiversity on the planet even more than a tropical rainforest. Though the coral reefs distributed in less than one percent of the ocean floor, they provide habitat for more than 25% marine life with more than 4,000 world’s fishes. They act as protective nurseries to many fish species, and shelter small fishes to grow. Coral reefs diversity is so rich that we do not have a firm count on all the species that live within it and every year discover new species.” There are about six thousand coral species in the world, in which few are growing in warm shallow waters near coastlines while others in the dark, cold seafloor of the open ocean.

22.1  Introduction

Plant pests have been part of man’s environment for a long time. Traditional agriculture, which included diverse crops and indigenous crop management practices, provided little opportunity for pests to build up and spread rapidly (Smith and Allen, 1954). Crop production is constantly threatened by increasing difficulties in controlling insect pests, which are a major impediment to improved livelihoods of poor farmers. However, in the quest to increase food production for the growing population, use of pesticides became a norm in crop management. Pesticides became an integral part of the process owing to losses from weeds, diseases and pests reducing the harvestable produce. Use of pesticides along with high yielding varieties, irrigation and improved seed did result in increased productivity. But the rampant use of these chemicals, under the adage, ‘if little is good, a lot more will be better’ has played havoc with human and other life forms.

Ecology is the inter-relationship between organisms and their environment. Weed ecology is study of inter-relationship between weed and their environmneent. Simply, Ecology of weeds means the inter-relationship of weeds with climate, soil, crops and other biotic factors. Terrestrial weed species persist in the soil by virtue of dormant structures, typically seeds or vegetative perennating organs such as rhizomes, tubers and taproots. In dense infestations, the banks of seeds or underground meristems from which new plants may be recruited into adult populations can be exceptionally large. Rao (1968) estimated that in Cyperus rotundus L. tuber populations of 10 million per hectare were possible, whilst Soerjani (1970) calculated that Imperata cylindrica may annually produce six tones of rhizomes per hectare. Typically seed banks of annual weeds in arable soils contain from 1000-10,000 seeds per m2whilst in grassland the upper limit to this range may extend at least to 1 million per m² (Mortimer 1994).

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.

1.    The first step in an econometric study should be to___________.

(a) Develop the specification

(b) Collect the data

(c) Review the literature

(d) Estimate the unknown parameters

2.    OLS stands for what in Econometrics?

(a) Optimally linearized solution

(b) There is no such thing in econometrics

(c) Ordinary least squares

(d) None of these

Econometrics : Mathematics and sophisticated computing applied to economics. Econometricians crunch data in search of economic relationships that have statistical significance. Sometimes this is done to test a theory; at other times the computers churn the numbers until they come up with an interesting result. Some economists are fierce critics of theory-free econometrics.

Economic Appraisal : See Economic evaluation.

Economic Burden of Disease : See Cost of Illness.

Economic Competition : The effort of two or more parties to secure the business of a third party by offering, usually under fair or equitable rules of business practice, the most favorable terms.

Economic evaluation (Economic appraisal) : The comparison of alternative courses of action in terms of their costs and consequences, with a view to making a choice.

Economic Evaluation : The systematic appraisal of costs and benefits of projects, normally undertaken to determine the relative economic efficiency of programs. See also Cost-benefit analysis, Cost-effectiveness analysis, Cost-minimization analysis, Cost-utility analysis.

Economic indicator : A statistic used for judging the health of an economy, such as GDP per head, the rate of unemployment or the rate of inflation. Such statistics are often subject to huge revisions in the months and years after they are first published, thus causing difficulties and embarrassment for the economic policymakers who rely on them.

Summary

Food production starts with a good soil. No matter the kind of seed and good agronomic practices that are put in place without a good soil yields will be low and hence income. ISFM is a technology that helps to solve the problem of soil infertility and production.
 
Farmers only accept and adopt a technology if they see it to be superior to what they have been doing and it makes business sense. Farmers will not worry about the bigger picture of food security or increased production – they need to make a profit to support their household.

Definition of terminologies and concept

Variables: Variables are the characteristic, number or quantity which increases or decreases over time and takes different values in different situations. Variables are those, whose value varies according to the situations. For example, maize yield, Stover, fertilizer, labor, land, pesticides, etc.
 
Dependent variable: Variables whose value is dependent on independent variables. These variables take different values only in response to independent variables. Yield of maize is dependent on amount fertilizer, fertilizer application methods, labor, pesticides etc. So in this case maize yield is dependent variables while amount fertilizer, fertilizer application methods, labor, pesticides are independent variables. However in other situation, maize yield can be used as independent variables also.

Introduction

Soil erosion is becoming a global challenge, causing various effects such as reducing crop yields, degradation of water quality, leading to inundation, degrading land by making it unsuitable for agriculture and others. Moreover, it is a significant problem that poses a devastating impact on food security, livelihoods, and the environment. It not only depletes the fertile soil needed for agriculture but also leads to reduced agricultural productivity, loss of biodiversity, and increased vulnerability to climate change.

Life cycle cost analysis

Economics of solar energy devices can be calculated through life cycle cost (LCC) analysis. Total life cycle cost of a device is comprised of capital cost, maintenance cost, replacement costs for damagaed components and operational cost. Before adding these above costs, all future costs (C) are converted to present worth considering the relative rate of inflation (i) and discount rate (d).

Where, PW is the present worth of any future cost, i is the relative rate of inflation and d is the discount rate per year and n is the time period in years. Relative rate of inflation accounts for the escalted increase or decrease in prices of a commodity in comparison to general inflation rate. For any commodity, if the price escalation is expected as per the general inflation rate then relative rate of inflation is considered zero. In general case, relative rate of inflation is considered zero. Discount rate accounts the real value of money in future and in most of the economies of the world it is about 8-12%, and therefore 10% is considered in most analyis. The discount rate also refers to the interest rate used in discounted cash flow (DCF) analysis to determine the present value of future cash flows. The discount rate in DCF analysis takes into account not just the time value of money, but also the risk or uncertainty of future cash flows; the greater the uncertainty of future cash flows, the higher the discount rate. A discount rate of 10 % per year would mean that in real terms it makes no difference to a farmer whether he has ? 100 now or ? 110 in one year’s time. Conversely, a cost of ? 110 one year from now has a present worth of ? 100. For a future single cost in n^th year, the present worth of that cost is calculated using Eq (1). However, for future multiple payments, costs are to be converted to present worth for each year and then needs to be cumulated. For calculation of annualized life cycle cost (ALCC) of solar devices, annuity factor (AF) needs to be calculated for a period of life cycle of the device as follows:

Abstract

Himachal Pradesh is spread over the altitudinal range varying from 352-6975 m amsl. Horticulture in upper reaches and cereals in valley areas form the major components of land use. Temperate fruits amongst the different fruits grown in the state occupy a major share  with respect to area (68%) and production (90%). About 92 per cent of the total geographical area of the state is directly and indirectly influenced by fruits farming through changes in socio-economic structure. This paper has been prepared to highlight the socio-economic issues, technological issues, growth in the states economy and efficiency of the social indicators. This study shows that majority of the total population (80%) in the state has been affected positively by the apple farming business. The role of women has been considered equally important due to strong interaction between orchard and household management activities majority of the orchardists have been found to be marginal and small covering about 47.1per cent of the total area. Amongst all the temperate fruits grown, apple growers enjoy comparatively a better performance with respect to socio- economic indicators. A tremendous increase in area and production under apple has been found during the previous years.

Weed Management

The productivity of crops much depends on intercultural and weeding operation. The efficient management practices ultimately increases the yield level. The productivity is much dependent on various attributes starting from the variety, climate including human resource management and other factors known well to the farmers. It is estimated that nearly 30-50 per cent of the crop is lost due to weed menace in the agricultural fields. The farmers use various methods of weed control like cultural, mechanical, chemical and manual means. Encompassing all these control measures is known as integrated weed management.

The impact of biotic and abiotic constraints, the machinery revolution, faster access to information, city development, social and economic context, climate changes that affect agricultural products and people's movement from one region to another, population income, new cropping technologies adapted to people's demand for food diversification and supply, technical and genetic progress, the impact of biotic and abiotic constraints, the machinery revolution, faster access to information and city development have all had an impact on agricultural market trends over the last ten years. (Bonciu et al., 2020a, Bonciu et al., 2020b).

Biodynamic farming, a holistic and ecological approach to agriculture founded by Rudolf Steiner, has gained prominence as a sustainable and ethical alternative to conventional farming methods. This method integrates ecological balance, soil fertility, and cosmic rhythms into farming practices. Despite its growing popularity, the economic viability and market dynamics of biodynamic farming present both opportunities and challenges. This article explores the economic aspects of biodynamic farming, including production costs, market demand, pricing strategies, and financial sustainability. It also examines the market trends, consumer preferences, and the role of certification in influencing economic outcomes. By analysing case studies and market data, this article provides a comprehensive overview of the economic and market considerations of biodynamic farming, offering insights into its viability and impact within the broader agricultural industry.

Abstract
Economic and policy considerations play a crucial role in shaping the landscape of modern agriculture. As the sector faces increasing pressures from global population growth, climate change, and resource constraints, understanding the economic dynamics and developing effective policies are essential for fostering sustainable agricultural practices. This chapter explores the economic factors influencing agriculture, including market dynamics, financial viability, and investment strategies. It also examines key policy considerations, such as regulatory frameworks, subsidies, and international trade agreements. By analyzing these aspects, the chapter aims to provide a comprehensive overview of how economic and policy considerations impact agricultural development and sustainability. It offers recommendations for policymakers, stakeholders, and industry leaders to create a more resilient and equitable agricultural sector.
Keywords: Economic considerations, policy frameworks, agriculture, market dynamics, financial viability, investment strategies, subsidies, international trade agreements, regulatory frameworks, sustainable agriculture.

Abstract

The temperate fruits have shown a remarkable progress as about 68 per cent of the total area under fruits and about 91 per cent of the total production of the fruits in the State is contributed by these fruits. The economic analysis of secondary data shows the increasing trend of area under fruits, vegetables as well as production of these crops in the State over a period of time.  Although maximum increase has been found during the last about 5 decades in case of fruits (about 236 times) yet production of vegetables has shown an increase of about 83 per cent  during the last about ½ decade. Similarly flower crops cultivation has also been increasing in the State which has been clear from the increasing number of flowers growing cooperative societies (48 in no.) in the State along with area  (129 ha) under different flower crops (Anon., 2004-05). More emphasis has been laid on diversification of crops so as to make proper use of limited land and other critical inputs. Economic analysis of primary data has shown benefit-cost ratios of fruits, vegetables and flower crops almost in the same range, i.e. maximum Rs. 4.50:1 to minimum 1.53:1, so with meager holding size, vegetable crops and floriculture have been found to be the best option of diversifying crops along with fruits growing so as to reap better remuneration from use of scarce resources.

Cost of Cultivation

The expenditure incurred from sowing to harvest including the field preparation can be worked out and expressed in Rs. ha^-1.

Gross Return

Total income obtained from multiplication of unit cost of main product as well as byproducts and its total yield and expressed in Rs. ha^-1.

Net Return

Net return is obtained by subtracting cost of cultivation from gross return and expressed in Rs. ha^-1.

Net return = Gross return – total cost of cultivation

6.1 Introduction

Urbanization is now a global phenomenon, but in developing countries the implications are more pronounced. Natural growth of population, reclassifications of habitation and migration trends are important in urban population in India. The population of India, which accounts for 27 per cent of the total population, was 285 million according to 2001 census. International experience shows that the pace of urban development accelerates when a country’s urban population crosses close to 25 percent of the total population (like in India).(Kumar and Chakrabarti, 2010). 

There are certain inherited traits (characters) in various species of livestock which are economically important. These traits have to be improved for increased production like milk, meat, egg, wool, etc.

Weaning to 210 days: Weight in kg of feed consumed for producing one kg of live weight for the period from weaning to 210 days of age.
10 Mortality percentages (as percentage)
Pre-weaning mortality: No. of piglets died during the period birth to weaning (28/56 days) the number of piglets born alive.
Post weaning mortality: Number of piglets died during the period from 28/56th to 365 day to the total number of piglets available at weaning.
Adult mortality: Number of adult pigs died to the number started at one year (in percentage).
List of registers to be maintained:
• Birth register
• Youngstock register
• Adult stock register
• Disposal register
• Mortality register
• Weighment register
• Farrowing and growth record
• Service register
• Boar performance register
• Sow performance register
• Veterinary register
• Feed efficiency register
• Account register

Livestock manure is principally composed of organic material. When this organic material decomposes in an anaerobic environment, methanogenic bacteria produce methane. These conditions often occur when large numbers of animals are managed in confined areas (e.g. dairy, swine, and poultry farms, and beef feedlots, where manure is typically stored in large piles or disposed off in storage of lagoons or tanks).

Manure management will always be a part of livestock production. Management practices will have a significant impact on the environment regardless of the size of the operation. Producers who make wise manure management decisions help to maintain a healthy environment now and for generations to come. To reduce the risk of air or water quality damage from manure, understand how manure impacts air and water quality, keep the public in mind when locating, expanding or maintaining a facility, reduce the amount of material entering the waste stream, collect and store manure to preserve nutrients and minimize gas/odour emissions, apply manure to fields in a way that most fully utilizes the available nutrients, follow compositing to increase manure value, establish bio-gas unit as an alternate energy source and for the electricity generation and if possible integrate with fish production to augment income.

Based on the observations a model system of waste management was designed by systematic and scientific integration of a bio-fuel unit, settlement and slurry processing unit, aerobic composting, traditional composting, and preparation of value added products like Panchagavya, Jeevamritham, packed dried dung and fresh cow urine. There were no reports of odour or water pollution from nearby water sources. The overall results of the waste management indicated that this integrated system can be recommended as a model for waste management in dairy enterprises with beneficial effects on economic efficiency, environmental hygiene and quality control.

INTRODUCTION

The terms agro-forestry and farm forestry are used interchangeably in India with respect to the establishment and/or management of trees on farms for productive purposes. It also particularly recognizes the use of trees and shrubs on farms to support agricultural production, protect soil and water resources, enhance biodiversity, sequester carbon, and improve landscape values. Lundgren (1982) defined “Agroforestry as a collective name for land use systems and technologies where woody perennials are deliber-ately used on the same land unit as agricultural crops and/or animals, either in some form of spatial arrangement or temporal sequence. In agroforestry systems there are both economical and ecological interactions between the different components”. It has been proposed that including a tree component within the farming system, either on bunds and boundaries (sequentially with crops) or intercropped in an agroforestry type configuration, can lead to increased land productivity while diversifying the farming enterprise (Atta-Krah et al. 2004; Huxley 1999; Young 1989), and increase economic security for small farmers (Russell and Franzel 2004).

Abstract

Three seepage tests were carried out for an earth canal at Rawakeeb Research Station (RRS)-west of Omdurman and an average seepage rate of 3.4 m/day was obtained. This value suggests that irrigation canal at RRS should be lined. In addition to that preliminary economic evaluation showed that canal lining is imperative in RRS. A concrete slab form was well designed for lining of RRS canal. Precasting technique and construction technique provided the required water tightness. Economic evaluation was done for RRS canal to investigate the extent of occurrence of supposed advantages, and to estimate costs and benefits and rate of return to lining. The capital expenditure (C), net present worth (NPW) and benefit/cost ratio were found to be 2600.4, 1961.9 and 1.3 respectively which offers a good indicator to adopt the technique.

4.1 INTRODUCTION

India enjoys a wide range of climates and agro-meteorological zones which are suitable for growing various kinds of horticultural crops like fruits, vegetables, f lowers, spices and condiments, plantation crops, and medicinal and aromatic plants.

India is the largest producer, consumer and exporter of spices in the world. India stands second both in production of fruits and vegetables next to China. China contributes 21.2% in the world fruit production whereas India produces 12.6%. When we think of vegetables, China produces 49.5% and India produces 14.09%. India is the largest producer of Mango, Banana, Papaya, Coconut, Arecanut, and Cashewnut in the world. In the country, Andhra Pradesh (13.0%) is the leading state in fruit production followed by Maharashtra (11.2%). In case of vegetables, Uttar Pradesh stands first occupying 15.1% share followed by West Bengal and Madhya Pradesh in the range of 14.6% and 10% respectively. In cut flower production West Bengal ranks first.

Total horticultural production for the year 2017–18 was 311.71 million tonnes from cropping area of 25.43 million hectares of land and an estimated production for the crop year 2018-19 is 314.87 million tonnes from an area of 25.6 million hectares.

8.1 Economic Geology and Ore Mineralogy

8.1.1 Economic geology

Economic Geology deals with the comprehensive study of mineral deposits including their processes of formation and uses. By applying the principles of geology, a mining engineer is able to exploit such deposits profitably for the use of Man.

8.1.2 Ore mineral

An ore is a term applied usually to that part of a metalliferous mineral deposit that can be utilized profitably as a source of one-or-more metals, this term now is widely used for the usable part of many non-metallic (non-metalliferous mineral) deposits, like barite, fluorite, sulphur, etc.

8.1.3 Gangue mineral

An ore is usually a mixture of one or more usable minerals (ore minerals) and one or more unusable minerals (gangue minerals). The usual gangue minerals are quartz and other forms of silica, calcite, dolomite, siderite, barite, feldspars, garnet, chlorite, kaolin, fluorite, apatite, pyrite, pyrrhotite, arsenopyrite, and sometimes the gangue material is the country rock or host rock itself in which the ore minerals occur. Sometimes, the gangue minerals may also be utilized as by-products of the ore deposit. The nature and proportion of the gangue influence the economic value of an ore to a great extent.

Introduction

Any project is undertaken and an investment is made with expectation of realizing benefits out of it. This applies to projects both in the private domain as also in the public domain. Hence, it is imperative to assess the benefits derived from the project investment over its entire economically viable. The extent to which project contribute to various aims of development (benefits) and make use of scarce resource (costs) can differ widely. A proper project preparation requires an assessment of the various benefits and costs associated with execution of a project. Methods to determine, analyze and assess the relevant benefits and costs of a project are known as cost-benefit analysis. The cost- benefit analysis ensures that all the relevant factors that contribute to a project’s net benefits are systematically taken into account, whether they relate to an individual, a firm, a social group, the public sector or the country as a whole.

There are many tools or criteria for the financial evaluation of projects. However, the important and commonly used evaluation criteria are simple Rate of Return, Payback Period, Net Present Worth, Benefit- Cost Ratio and Internal Rate of Return.

Economic appraisal and evaluation helps the decision makers who are saddled with the responsibility to prioritize measures in a situation with enormous needs and quite limited resources. Government planners as well as donor agencies are all in need of enough data in order to make rational choice or decision in selection of investment alternatives. Most of the economists believe that economic analysis cannot give the final answers. There will always be lack of data, uncertainty about the future, disagreement on the methods, and similar issues. However, economic analysis, if properly done, can indeed be of much help to decision makers.

9.1 ECONOMIC LOSSES DUE TO ANIMAL DISEASES

Economic considerations are increasingly forcing their way forward in the decision-making processes of animal health management. With the continuing intensification of livestock production systems, the economic implications of livestock diseases have become increasingly important at both farm and national levels, as they represent avoidable waste of scarce resources (McInerney, 1988). From an economic point of view, an animal disease either destroys the basic resources, reduces the attainable output, dwindles the efficiency with which the resources are converted into products, or decreases the economic value of products (McInerney, 1995).

The effects of a disease present in an animal or herd may be manifested by stunted growth, lowered production, delayed maturity, delayed conception, mortality, reduced resource (especially feed) use efficiency, etc. These negative impacts of a disease demand more resource(s) than usual, resulting in higher expenditures for the same output and reduced farm income. Apart from these negative effects at the farm or herd level, animal diseases lead to economic losses at the regional, national, and global levels too by increasing animal mortality, reducing productivity, increasing disease control costs, swelling losses in animal trade, decreasing the market values of livestock and their products, and ultimately ending at food insecurity. These economic impacts of livestock diseases, besides their social impacts, have now been recognized globally, in both developed and developing countries, necessitating quantification of the economic impact of animal diseases as an urgent and important step to support the prevention and control decisions for improved animal health to ensure better rural and global economy.

Fishes are used by human beings in different forms from time immemorial millions of human beings suffer due to hunger and malnutrition and fishes from a rich source of food, which has following importance:

1) Fish is an excellent food for mankind is more easily perishable than cattle, sheep and chicken.

2) Fish flesh is easily digestible by child and man.

3) Fish flesh has very great nutritive and medicinal values.

4) Fish flesh contains proteins, bass, vitamins, waters and minerals.

5) All the essential required amino acids are present in the fish flesh.

6) Fish flesh contains proteins about 13-20 % and it is easily digestible and nutritional.

7) Fish flesh is highly perishable commodity constituted as 60-80 % water.

8) Fish flesh contains about 1-8 % fats or oils and it is more important value of fishes.

47.1 Introduction

Fish are one of the most important groups of vertebrates and have always been a significant species in man’s life, influencing it in a variety of ways. Fish are highly valued in human civilization for their food, cooking, and nutritional value. They have significant economic, nutritional, medicinal, industrial, aesthetic and religious values, and they employ millions of people worldwide. Several species are sought after as luxury foods in high-end restaurants. They help to ensure food security in many parts of the world by serving as a valuable supplement to varied and nutritious diets.

1. Introduction

Horticultural crops have emerged as a cornerstone of India’s agricultural sector, wielding substantial influence over the nation’s economic landscape. Comprising an extensive range of fruits, vegetables, ornamental plants, plantation crops, spices, and medicinal herbs, this sector has witnessed remarkable growth and transformation in recent years. The significance of horticultural crops extends beyond sheer economic value, permeating various facets of Indian agriculture and socio-economic development (Ravichandra & Ravichandra 2014).The unique agro-climatic diversity of India allows for the cultivation of an unparalleled variety of horticultural produce, contributing to its global prominence as a horticultural powerhouse.

Introduction

Salinity is a significant abiotic stress faced by plants, particularly in semi-arid and arid regions of the world, where annual evaporation exceeds precipitation. In addition, approximately half of all the world’s irrigated areas are subjected to secondary salinization, alkalization, and waterlogging. About 8.85 million ha of land in India is degraded due to salinity and alkalinity problems. Besides the naturally occurring salt-affected soils, the extent of man-made salinized soil is also significant. Salt accumulation in the root zone layers of soils becomes a major constraint to agricultural productivity. However, such lands can effectively be utilized for salt-tolerant biological systems.

To survive under high salt concentrations, some plant species evolved well adapted morphological and physiological characteristics, allowing them to proliferate in saline environments. These species are known as halophytes. Halophytes constitute a small fraction of total plant species; they represent a wide diversity of plant forms and habitats and are of immense significance in expanding salinity problems and decreasing freshwater supply for agriculture. These salt-tolerant species possess enormous taxonomical plant forms and habitat diversity. Taxonomically, the species belonging to Poaceae, Cyperaceae, Chenopodiaceae, and Asteraceae families constitute a significant share of salt tolerant species of north-western hot arid regions of India. In the herbaceous plant group, the species of the family Poaceae are most abundant. In the case of woody perennials, Chenopodiaceae, Tamaricaceae, and Salvadoraceae families are essential as true halophyte and facultative halophyte species.

The vegetable crops like knol-khol, Broccoli and kale belong to the genus brassica of the cruciferae family. They are essentially cold weather, hardy crops and thrive best in cool moist season. These crops, if grown under warm conditions, the produce become pungent due to development of glucocide called sinigrin containing sulphur. According to Chowdary (1967), the crops of this group have developed from wild cliff cabbage, also known as cole wrots, from which the name cole has been given. Their taste founds to be more sweat in hills due to low temperature and constitute at top in the list of preference vegetables for people all over India.

This chapter attempts to describe the cultivation of these three cole crops, exclusively grown in hills of India.

Knol-Khol

Knol-khol (Brassica oleracea var. gonylodes) is a well known green–leafy vegetable, which is consumed with leaves and knobs. It is popular among Kashmiri people and the people of hilly areas. Its cultivation is confined to Jammu and Kashmir, Himachal Pardesh, West Bengal, Uttranchal and Punjab. Due to its year round demand and conducive agro-climate available in J&K, it can be cultivated round the year. The crop is of short duration and be grown three to four times a year. Thus it gives very high productivity per unit area.

After assessing the prevalence or incidence of the disease concerned, the next step is to quantify the economic losses due to that disease by classifying and presenting all the information available on the losses, expressing these in monetary values, and identifying and quantifying the indirect losses attributable to a disease, to the extent possible. Usually, most of the negative effects of diseases can be conveniently estimated in terms of reduced output, mortality, reduced weight, delayed maturity, and treatment cost, directly. However, quantifying the indirect effects of the disease will be complex, but it is not impossible.

As we saw earlier, the economic impacts of animal diseases can be measured using statistical / epidemiological methods and economic methods. Economic methods of disease loss estimation include the Gross Margin Analysis, Enterprise Budgeting, Equi-Marginal Principle, Partial Budgeting, Cost Benefit Analysis, and Decision Analysis.

INTRODUCTION

Farming acts as the primary occupation of majority of the population in India. According to National Sample Survey Estimate, about 49% of the Indian population is dependent on agriculture and allied industries (GOI, 2014, CIA, 2012) making it the largest source of employment to the people of India. Although, being a second largest food producing country in the world (Sarkar, 2009), the contribution of agriculture to the GDP has been declining. The contribution of agriculture to Indian GDP has declined from 30% in 1991 to 15% in 2011-2012 to 13.7% in 2013 (Economic Survey. 2013-2014). This decline is also accompanied by a decline in the participation of people in Indian farming sector. In fact between 2001 and 2011 about 9 million people have quit farming, which is about 2 million more than the decline noted in the previous decade (GOI, 2011). This figure equates to about 2035 farmers quitting farming per day. The recent census (GOI, 2011) also highlighted that for the first time in four decades an absolute decline (about 7%) in the cultivators has been noted.

During the last visit of Barak Obama in the year 2011, he pointed out that India is fortunate to have a youth population with a half of the total population being under the age of 30-35 years. Out of 600 million young people, over 60% live in villages and majority of them are educated. Mahatma Gandhi considered that migration of rural youth from villages to town and cities as the most serious form of brain drain affecting adversely rural India’s development. The National Commission on Farmers stressed the need for attracting and retaining rural youth in farming. Recently, National Sample Survey has indicated that over 45% people want to quit farming under these condition there is need to persuade educated youth including farm graduates to stay in villages and take up agriculture as a profession. There are various economic opportunities for farm graduates which are discussed below:

21.1 Cost Principle

 We know that

 TC = VC + FC

 and Net Revenue = TR-TC.

In the short run, gross revenue (G.R.) must cover the V.C. The maximum net revenue is obtained when MC = M.R. If GRs VC, the guiding principle should be to keep increasing production as long as MR > M.C. In the short run, MC = MR point may be at a level of input use that may involve a loss instead of profit. Yet at this point, the loss will be minimised.This situation of operating the farm when MR > AVC but

Among various animal husbandry enterprises, poultry production has emerged as number one position and attained industrial status in many countries, including India.

This tremendous growth in poultry production is due to the following reasons:

There is no religious taboo towards poultry and poultry products.

Egg is the most nutritious, natural, unadulterated and easily digestible food with the highest biological value.

Eggs can be consumed by all age groups and economic classes, since it is the cheapest among all the nutritious natural foods on the earth.

Among various meats, poultry meat has the highest protein, lowest fat and cholesterol content.

Poultry is the best converter of feed into meat and eggs. A hen needs only 1.5 kg feed to produce 1 dozen eggs. Similarly a broiler needs less than 2 kg of feed to produce one kg broiler meat whereas other species need more than 3 kg of feed to produce 1kg of meat.

Poultry has the shortest generation interval among various livestocks.

Introduction

In recent decades, economic reforms centred around liberalization, privatization, and globalization have emerged as fundamental drivers of economic transformation on a global scale. These reforms represent a departure from traditional state-centric economic models, emphasizing market-oriented approaches and greater integration into the global economy. This introduction sets the stage for a deeper exploration of the interconnectedness and impact of these reforms on economies worldwide, highlighting their significance in shaping the contemporary economic landscape.

Historical Background

During the 1980s, India found itself facing an economic crisis characterized by a gradual decline in its economy. By the decade's end in 1990, the country was plunged into a severe Balance of Payments (BOP) crisis. This crisis was caused by a mounting fiscal deficit and escalating overvaluation of the currency. Compounding matters, the invasion of Kuwait by Iraq occurred in the same year, triggering a significant spike in oil prices and a corresponding drop in remittances from Indian expatriate workers. The resultant increase in the cost of purchasing oil and the rapid decrease in net factor income from abroad exacerbated India's economic woes.

One of the chief aspects of Entomology is the study of insects from the standpoint of their innumerable relations and activities affecting the interests of man. More than any other living organisms, insects have more intimate and complex relationship with man. It is well known that insects affect human interests both for good and bad. However, their injurious activities are of much greater concern to man than the beneficial aspects of their activities. Several insects are beneficial to man in several ways, both directly and indirectly and there are scores of other insects, which do not interfere with the interests of man in any way.

From the time man stepped into the domain of insects, a stifle has started between the insects and man. To meet his various demands for food, clothing, shelter and various other requirements, man cultivates various crops and raises many domesticated livestock. Unfortunately for man, insects also have started depending on these for their living. When the requirements for man and insects happen to be the same, a race is on for their survival and existence. Insects attack plants and livestock and cause extensive damage and economic loss. So, man considers such injurious insects as his enemy and to safeguard his interests tries to destroy them by various means. However, man’s supremacy and intelligence have not proved a match to the rapid propagation of insects and their various adaptations to withstand any hardship and adverse conditions. In the effort to gain an upper hand, it has not been possible for man to destroy the unwanted insects completely and the struggle is going on as a never-ending ordeal.

Introduction

Tripura is a small state blessed with rich flora and fauna. The small scale aquaculture with other agricultural enterprises and allied economic activities are common practice followed by majority of the farmers in rural areas. The small scale aquaculture is not only common in rural areas but is also practiced in the backyard ponds in urban which have multiple uses. The homestead fish production is common in Tripura because fish is highly preferred food item in the diet of about 95% people of Tripura. But due to the subsistence level of aquaculture practices in the state, productivity and production of fish is quite insufficient to meet out market demand for fish. Though the state Government and other stakeholders of fish production systems are making relentless effort to enhance the production to the level of 74 MT to meet the current market demand, the average fish productivity in the state is comparatively lower as compared to many states of the country. The lower productivity is an important issue and one of the major impediments in enhancing fish production in the state. The experts and research finding have identified several factors such as short culture period, acidic nature of soil and water, more iron content, poor quality of seed, improper feeding, lack of technical knowhow etc are the main reasons behind the lower productivity. Still, there are many other issues uncovered and unaddressed which may be the lower growth of fishes and consequent lower fish productivity. For instance, factors like pond size and number of species in the culture system at farmers’ level may also have impact on the farm productivity. It is necessary to adopt region-specific models for furthering freshwater aquaculture in view of the available aquatic biodiversity as well as the consumer preferences and economics of operations in different parts of the country (Ayappan et al, 2009). This is particularly important considering polyculture is the major form of aquaculture in the state. Datta 2015, has opined that due to consumer’s preference, high market value as well as conservation-revitalization of various cultivable species, importance of diversification in culture of various species has been found of immense importance in the present aquaculture scenario. Among the species, endemic minor carps, catfishes in monoculture, perches, murrels live species are important. In this study, an attempt has been made to analyse level of species diversification at the farm level and their socio-economic and scientific significance at farm level.

As the agricultural sector progresses, brands must implement a cohesive strategy that harmonises developing technologies, adaptive regulations, and a profound comprehension of changing consumer psychology. This chapter examines how the strategic integration of these three factors can augment brand value and foster enduring consumer loyalty. The chapter initiates by delineating the fundamentals of brand development within the agricultural sector, emphasising the essential components of brand identification and the principal economic and psychological factors influencing customer endorsement of agri-brands. It subsequently explores the crucial function of technology, analysing how digital instruments, blockchain, artificial intelligence, and immersive technologies might transform branding tactics and enhance transparency and consumer involvement. The policy frameworks that direct brand creation are equally significant. This chapter examines the influence of regulatory requirements, sustainability initiatives, and intellectual property rights on brand integrity, credibility, and access to global markets. It subsequently examines the economic benefits of technology-driven and policy-compliant branding, including enhanced customer willingness to spend, elevated brand loyalty, and competitive advantages. This chapter emphasises the significance of psychological resonance for sustained brand success, while also exploring the roles of emotional branding, persuasive narrative, and the utilisation of cognitive biases. It ultimately offers techniques for the integration of technology, policies, and psychological involvement into unified brand creation, while also tackling the issues of reconciling innovation with compliance. This thorough chapter provides agricultural companies with case studies and forward-looking insights to effectively manage the changing landscape, yielding both substantial economic benefits and lasting emotional ties with consumers.

Economic System

The three economic problems What, How and to whom to produce are common to all societies or economics. But different countries follow different approaches to solve basic economic problems. These approaches are called economic systems. There are 3 important economic systems.

1. Command economies
2. Market economies and
3. Mixed economies

1. Command economies (Socialist economies): In a system like this, the government controls all aspects of production and distribution. Such a government might be dictatorial or it might be democratic. Main features of socialism are public ownership of means of production, Economic planning, Economic equality, lack of competition, elimination

Decisions need to be taken by the farmer as to how to implement disease management in the most effective and economic manner. Many of these decisions are taken a long time before any diseases appear, such as the crop rotation, time of planting, amount of fertiliser, etc. During the growing season, however, continual decisions need to be made regarding disease management.

In modern poultry farming, successful management relies on accurate and complete daily record keeping. Some of the traits may influence the profit of farm, thereby affecting the economics of the farm than the other traits, and hence they are called economic traits. Economic traits can be defined as those traits which are economically important and improvement in these traits would increase the profit of the farm. These traits are generally assumed to be controlled by the genes at larger number of loci. Some of the economic traits in egg and meat type chickens are as follows:

Introduction
The economic transformation through information technology (IT) has emerged as one of the most influential drivers of modern economic development across the globe. In the 21st century, IT has catalyzed sweeping changes in industrial processes, global markets, and the overall economic structure, impacting everything from productivity to business models, labor markets, and governmental policy. The proliferation of IT has led to profound shifts in economic paradigms, influencing sectors ranging from agriculture and manufacturing to services and finance. The integration of IT into these various domains has spurred growth by fostering innovation, reducing inefficiencies, improving resource management, and creating new opportunities for economic development.

Abstract

Solid waste, the creation of human being, is taken today the shape of a Demon to kill its creator by polluting breathing air, drinking water and essential food materials. It spreads different infectious killer diseases if not disposed off timely. Municipal authorities are spending lakhs of rupees to collect and transport solid wastes to dump-yard. Presence of both biodegradable and non-biodegradable wastes together in dustbin makes the disposal problematic and Municipal workers handling solid wastes suffer injury and disease infections. Municipal authority can clear about 50 percent of solid wastes either by dumping in low lying areas or by burning in open places causing unwanted environmental pollutions. Incinerations with electric producing facility, pyrolysis, dumping in properly built concrete landfills, Pelletization are scientific techniques for solid waste management. But recycling as resource materials is the best economical approach. Since non-biodegradable wastes can be sold to scrap dwellers for further processing it offers income opportunity. Biodegradable wastes can be converted to good quality vermicompost, which is also a marketable product and fetch good income. Different activities during recycling of solid wastes offer employment opportunities to literate & illiterate, skilled & unskilled, male & female, young & old workers. The present ‘Treatment at the end of pipe’ approach is to be changed by ‘Treatment at source’ approach.
