1. California mastitis test

The California mastitis test (CMT) is conducted during milking of lactating cows. The CMT paddle is used to collect about three to four ml of fore milk from each quarter of cows after discarding few streams to which an equal volume of CMT reagent (composition mentioned below) is mixed immediately by circular motion (Fig. 1). The reaction is graded by intensity of gel formation and color changes as follows:

This chapter is framed with different factors relating to socio-economic profile of shrimp farmers in Dhamara coastal zone. Shrimp farming offers significant employment opportunities, which may help alleviate the poverty of the local coastal population in many areas, if it is properly managed. The published literature on that topic shows large discrepancies, and much of the available data is of anecdotal nature. Estimates of the labor-intensiveness of shrimp farms range from about three times less to three times more^] than when the same area was used for rice paddies, with much regional variation and depending on the type of farms surveyed. In general, intensive shrimp farming requires more labour per unit area than extensive farming. Extensive farms cover much more land area and are often but not always located in areas where no agricultural land uses are possible. Supporting industries such as feed production or storage, handling, and trade companies should also not be neglected, even if not all of them are exclusive to shrimp farming.

Typically, workers on a shrimp farm can get better wages than with other employments. A global estimate from one study is that a shrimp farm worker can earn 1.5-3 times as much as in other jobs; a study from India arrived at a salary increase of about 1.6, and a report from Mexico states that the lowest paid job at shrimp farms was paid in 1996 at 1.22 times the average worker salary in the country.

8. Introduction

The idea of sustainable development stands on the concept of maintaining the best possible environment within the availability of minimal resources and for the convenience of the society. Now-a-day the term “sustainability” gained a lot of attention due to challenges and problems faced in tackling the current situation of global pollution. One of the vital areas of research needs to be addressed in concern with sustainable development is the new innovations to enhance sustainability (Silvestre and Silva, 2014). 

Introduction

An entrepreneur is someone who starts or runs their own business. By having an equity stake in the company, the entrepreneur can profit greatly if things go well; however, they also take on a great deal of risk-far more than a regular employee of the company. Financial, career, emotional, and overall business risks are all examples of entrepreneurial risk. Because there is so much at stake in starting and growing a successful business, there are very specific skills that an entrepreneur usually requires to be successful. It could be a picture of a talented college dropout or a seasoned business professional with an uncanny ability to predict the next big thing. Replace whoever the persona is with ourselves. A successful entrepreneur does not have a specific demographic or personality profile. We can be entrepreneurs regardless of our age, race, gender, sexual orientation, socioeconomic status, or upbringing if we have dedication, drive, and essential business skills. Unlike personality traits and demographic information, entrepreneurial skills can be learned and practiced. If we want to pursue entrepreneurship, use this list to assess our strengths and weaknesses and determine which skills we need to develop before launching our venture.

Radish, turnip, carrot and beet root are the major root crops grown in the country. In addition, root crops like rutabaga, parsnip, salsify, chervil and celeriac are grown in a limited scale in different areas. Though the crops belong to different families, their cultural requirements are uniform. The common features of root crops like radish, turnip, carrot and beet root are:

• In all root crops, the tap root and a portion of hypocotyl develop into fleshy root.
• All root crops are cool season crops and are the best grown during winter in plains and spring-summer in hills of North India
• All crops, except beet root, exhibit two distinct groups, viz., tropical or Asiatic or annual types and temperate or European or biennial types. In beet root, tropical annual types are not available.
• Seeds of annual types are produced in plains. Biennial types require a chilling temperature, after attaining or completion of vegetative phase, for transforming to reproductive phase. Since this chilling temperature is available during winter at high altitudes, seed production of biennial types are practiced only in hills of North India.
• All root crops require well drained loose and friable soil without any clods for raising a good crop. Seeds are sown on ridges or on raised beds for proper development of roots.

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.

The basic equipment for performing laparoscopy includes the laparoscope and corresponding trocar and cannula, light source, gas insufflator and the Veress needle. Laparoscope applicable for use in the small animals (dog, goat, sheep and lab animals) ranges in diameter from 2.7 to 10 mm in diameter, however, a 5mm diameter telescope is suitable for most cases and 2.7mm may be required for toy breeds of dogs and lab animals. A 0 or 30 degree direction of vision provides the operator with a “normal’ field of view and has proven most useful. Authors are using a 5-mm diameter 30-degree field of view telescope for routine diagnostic laparoscopy. The 5-mm diameter is adequate for most all small animal procedures in animals of variable size. The 0-degree designation means that the telescope views the visual field directly in front of the telescope.

Rainfed farming has a distinct place in Indian Agriculture, occupying 67% of the cultivated area, contributing 44% of the food grains and supporting 40% of the human and 65% of the livestock population. It is characterized by resource poor farmers, poor infrastructure and low investment in technology inputs (Singh, 1999). The land use in rainfed areas is quite diverse with a variety of crops, cropping systems, agroforestry and livestock farming. The productivity levels have remained low over the years and the share of rainfed crops in the total food grain production has been declining. The rainfed ecosystem suffers from the problems of (i) frequent droughts due to high variability in the quantum and distribution of rainfall, (ii) poor soil health due to continued degradation and inadequate replenishment of nutrient exhaustion, (iii) low animal productivity due to an acute scarcity of fodder and (iv) low risk bearing capacity of farmers due to poor socio-economic base, credit availability and infrastructure.

Climatic factors like increase in temperature, carbon dioxide (CO₂) concentration, moisture, and other factors directly or indirectly affect agriculture, which have been elaborately dealt in previous chapters. Climate change causes weather variability that may result in low production, hike in price of agricultural commodities including food grains, vegetables, fruits, meat, egg and milk. It is now realised that climate resilient agriculture (CRA) will be imperative to reduce the vulnerability of agriculture to the climate change.

1. Introduction
The world’s ecosystem is facing significant challenges because of risingpopulations, more urbanization, and industrialization (Juwarkar et al.,2014). Significant environmental contamination has been caused by moderncivilizations, industrialization, population increase, intensive agriculturalpractices, human activities, and technological advancement (Lalevic et al.,2016).

Aquaculture is the cultivation of fish, molluscs, crustaceans (shell fish) and aquatic plants in controlled conditions, provides an increasingly significant proportion of food production globally. The sector has represented the greatest growth of all food production systems in the last two decades and an estimated 10% yearly increase in output is likely to bring productivity to a predicted 47 million tonnes in the year 2010 (Pedini and Shehadeh, 1997). Significantly, the greatest contribution to total production and the greatest rate of uptake of aquaculture activity is in the developing world. More than 82% of the total global yield in 1999 was produced by developing countries (GESAMP, 2000) and growth rates between 1984 and 1995 were six times higher than that from developed countries (Rana, 1997; Tacon, 1996).

Introduction on Climate Smart Agriculture (CSA)

Extreme weather conditions like rainstorms, high wind pressures, high temperatures, flood and drought situations have profound influence on agriculture. Climate and agriculture are strongly interrelated universal processes and thus variations in climate influence agricultural activities (IPCC, 2007). The effects of climate change are seen in form of global warming, unseasonal and excess rainfall, and frequent natural calamities which affects agricultural production. At the same time emission of GHG to the atmosphere is a major source of climate change. The impact of climate change on crop yield, dairy and other livestock production including fishery will be felt in reduced production and consumption. Climate change will effect in additional increase in prices for main agricultural food crops such as rice, wheat, corn and soybeans (IFPRI, 2009).

A. PLANNING OF AN ORCHARD

Orchard is a long-term investment and needs proper planning and layout before establishment. Mistakes committed during planning and planting of fruit trees cannot be rectified. While planning and planting a new orchard, it is very important to carefully assess all the factors that will ultimately affect fruit yield and orchard sustainability. The aspects like location and site selection, suitability of soil and subsoil, suitability of fruit crop and varieties, plant spacing, market potential and source of nursery plants must be taken care of seriously. Thus, one should avail of expert advice on the establishment of new orchards and their proper maintenance.

Introduction

A symposium organized by the Food and Agricultural Organization (FAO) in 1966 and International Organization of Biological Control (IOBC) in 1967, felt the need for the development of a new concept called “Integrated control” which was later replaced by “Integrated Pest Management”. The origin of IPM was necessary after the serious failure of the chemical age which started in the 1940’s. The pesticides were used as the only tactic to completely annihilate the pests from the crop ecosystem, which did miraculously decreased the pests and increased the production of the crop extensively, but they failed to realize the balance of life, by nature and by virtue of the selection pressure pests started developing resistance against all kind of pesticides being dumped on them.While the pests were getting resistant, the dumped pesticides were accumulating in the environment and biomagnifying inside the bodies of animal (WHO, 1990; Alewu & Nosiri, 2011; Eskenazi et al., 1999). The indiscriminate use of pesticides led to the significant health hazard to the humans (WHO, 1990; Alewu & Nosiri, 2011; Sanborn et al., 2007; Mnifet al; 2011; Semchuk et al., 1992; Goad et al., 2004; McKinlay et al., 2008; Gasnier et al., 2009; Lin et al., 2015; Waddell et al., 2001), reproductive malfunction in male (Jamal et al., 2015), nervous system (Jaga and Dharmani, 2003; Rosenstock et al., 1991; Wesseling et al., 2002; Eskenazi et al., 2006), cardiovascular system (Hung et al., 2015) and ultimately death (WHO, 1990; Gunnell et al., 2007). From the lessons acquired of the hazards, the concept of IPM proposed the concept of “pest eradication” was replaced with “pest management”. There are more than 64 definitions of IPM but the most accepted one came from FAO (1967) which defined IPM as “a system in context with associated environment and the population dynamics of pest species, utilizes all suitable techniques and methods in as compatible manner as possible and maintains the pest populations at level below those causing economic injury”. IPM decreased the pest pressure of the crop and increased the productivity of the crop and income of the farmers. IPM is a complex approach that advocates the integration of several components such as physical, mechanical, biological, legal, ecological and chemical tactics, in a compatible manner in a complete ecological set up, so that natural mortality has a role in checking the pest population building up above economic injury level (EIL).

Introduction
Climate change, rapid population growth and limited natural resources such as water and soil pose significant global challenges today. There have never been such drastic repercussions on fruit output worldwide from climate change. In this sense, utilizing methods from the present era of nanotechnology can enhance fruit output and encourage sustainability. Fruit crops have a multitude of roles in world agriculture, making them essential. They supply vital vitamins, minerals and antioxidants that are necessary for maintaining human health and preventing disease. Fruit crops are important players in both local and foreign markets, bringing in large sums of money for farmers and generating a large number of job opportunities, especially in rural areas. Fruit orchards improve soil health and decrease erosion, which promote biodiversity and increase climate resilience. Furthermore, fruits are highly valued on a cultural and social level around the world, enhancing communal customs and culinary traditions. Fruit crops meet nutritional needs by diversifying diets and enhancing food security, which makes them essential
The term ‘nanotechnology’ is derived from the Greek word “nano,” which means dwarf. The development of nanotechnology is closely linked to a historic statement made by Nobel Prize winner Richard Phillips Feynman “There is plenty of room at the bottom”. Designing, characterizing, manufacturing and applying structures, devices and systems by manipulating their size and shape at the nanoscale scale is known as nanotechnology. A nanometer, abbreviated as nm, is one billionth of a meter, or 1×10-9 meters. Nanoparticles are structures with sizes between 1 to 100 nanometers. Nanotechnology may be very helpful in many areas of science and industry by utilizing the special properties of nanoparticles. Understanding and manipulating matter at the nanoscale is of special interest to researchers in the domains of science, medicine, agriculture and industry since materials at this scale frequently exhibit radically different properties from those at larger scales. Nanoparticles find extensive applications in the fields of biotechnology, electronics, textiles, biomedicine, communication technology, biotechnology and renewable energy. In the field of agriculture, innovative nanomaterials have demonstrated great promise for the creation of hybrid crop varieties, new high-efficient agrochemicals for crop protection and nutrition and new crop types through genetic engineering. Additionally, the use of nanomaterials enhances the production of nutraceuticals, the efficiency of pesticides and fertilizers, food processing, packaging, food safety and plant nutrition. It also reduces environmental pollution.

INTRODUCTION

The planning of new orchard is very important aspect of fruit glowing which needs special attention and care to make it more profitable venture. The climate and soil of particular area are the major chief natural factors in the orchard establishment. The proper combination of this governs the success of fruit growing
 
A. SUITABILTY OF CLIMATE FOR FRUIT PLANTS

Climate refers to an average condition of the atmosphere over a long period, whereas, the term weather refers to the current and temporary atmospheric conditions of an area. Climate is the principal factor for optimum vegetative and reproductive growth of plants. The success or failure of crop in a particular locality depends upon the prevailing climatic conditions. In our environment it is fundamental force which includes various components of climate like temperature, humidity, wind, light, rainfall, hail and frost. These factors should be taken care of for successful fruit production. All cultivated crops including fruit crops have certain natural threshold limits of the climatic parameters for their normal growth. The important climatic components which affect fruit crop production are given below:

The impetus for the development of aquaculture extends beyond food production. Aquaculture can help to diversify rural employment opportunities, reduce trade deficits, reduce pressure on living marine resources and rebuild depleted wild stocks (FAO, 2000b). The rapid development of coastal aquaculture, however, is now an area of critical international concern owing to the immense role it plays in transforming coastal landscapes and livelihoods. With the advent of new technology and rising global demand for fish and fish products, the basic character of aquaculture in coastal communities is changing dramatically. Traditional, low production forms of aqua-culture catering to local households are being supplanted by modern, resource intensive high production systems that cater to international markets. This restructuring has generated widespread concern over the contribution of aquaculture to the degradation of coastal ecosystems and the social and economic costs that are being passed on to the rural poor leading to growing inequality (Lakshmi and Rajagopalan, 2000).

There is large-scale conversion of wetlands including mangroves for other uses despite their valuable functioning, products and attributes. Normal market forces always favour the conversion of mangroves (and other wetlands) to other uses and ; many alternative uses of natural mangroves in tropical and sub-tropical coastal areas have produced disappointing economic results due to low and declining productivity (eg. abandoned shrimp ponds due to unscientific shrimp farming in formerly mangrove areas) (Dixon and Lal, 1997).

The large-scale destruction of mangroves for shrimp ponds has adversely affected the productivity of nearby fisheries and consequently the economic conditions of traditional fishermen households. The conversion of mangrove forest into shrimp ponds in the coastal areas in Asia including India is nothing but redistribution of income from poor fishermen to rich investors, mostly non-fishermen marine product industrialists and merchants. (Maler, 1998). The destruction of mangrove forests in India, China, Thailand and other Asian countries is synonymous with the destruction of fishing grounds of the traditional fishermen leading to their occupational displacement.

In a commercial horticultural enterprise, if the product is not marketed properly, safely and beneficially, all the investment, inputs, hard work goes in vain. Basically every commodity that is produced should reach the consumer and marketing is all about how the commodity reaches the consumer. There is no fun of producing any commodity if it does not reach the consumer.

The word market has been derived form Latin word “marcatus” meaning merchandise, where people conduct business. Market therefore refers to place where goods/ commodity and services are bought and sold.

Marketing is a sum total of business activities through which the goods and services are either bought or sold. Cundiff and Still defined marketing as “the business process by which products are matched with markets and through which transfer of ownership are affected.

1. Introduction

Country has vast network of 20 river basins with utilizable surface and groundwater resources of 1123 billion cubic meter (BCM). With the rising population, the per capita availability of water in India has declined from 5178 m³/year in 1951 to 1441 m³/year in 2015. About 60% of Indian population have per capita water availability close to or lower than the water scarcity threshold of 1000 m³/year. The per capita water availability will further decline to 1139 m³/year with increase in population. On the demand side, the gross water requirement for all users in India is expected to grow up to 1447 BCM in 2050 (CWC, 2010, GoI, 2015). With the massive financial investment by the governments and the farmers, net irrigated area in the country increased from 20.85 million hectare (Mha) in 1950-51 to 68.38 Mha in 2014-15 (DES, 2019). Although India is a world leader in irrigation infrastructure, still half of the total cropped area (51%) remains rainfed. Further, many studies have flagged sustainability and equity concerns in irrigation development in the country (Selvarajan and Roy, 2004;

1. Introduction
Oil spills are defined as the unintentional release of liquid petroleum hydrocarbons into the environment, predominantly impacting marine ecosystems. This form of pollution, often caused by human activities, can also occur onterrestrial landscapes. Spills typically result from the discharge of crude oilfrom sources such as tankers, offshore platforms, drilling rigs, and wells, aswell as from refined petroleum products like gasoline and diesel (Smith etal., 2019). While such incidents are primarily accidental, they may arise fromvarious circumstances, including inadequate storage or poor maintenance,leading tocontainerleaks. Historically, one of the earliest documented oil spillsoccurred in 1907 in Batum, a region then part of the Russian Empire (moderndayBatumi, Georgia). This incident, involving a collision between an oil-ladenship and another vessel in the Black Sea, marked the beginning of recorded oilspill events, though historical records from that time remain limited (Johnsonet al., 2021). The consequences of oil spills are profound, affecting both theenvironment and the economy. On the ocean’s surface, oil disrupts aquaticecosystems by blocking sunlight penetration and depleting dissolved oxygenlevels, which are vital for marine life. Crude oil compromises the insulating andwaterproofing properties of fur and feathers, leading to hypothermia and deathin oil-coated birds and marine mammals. Additionally, ingesting oil can causeseveretoxicity, while damage to habitats and reproductive systems often delaysthe long-term recovery of affected species. Coastal vegetation, particularly inecosystems such as saltwater marshes and mangroves, is also highly vulnerable
