Crop Domestication

Domestication can be loosely defined as the process of bringing of a wild species under the management of man. Domestication is the process by which genetic changes (or shifts) in wild plants are brought about through a selection process imposed by humans. Because of the role of humans, the process results in characteristics that are beneficial to humans but some that would be disadvantageous for plants in their natural habitats. It is an evolutionary process in which selection (both natural (frost tolerance) and artificial (large attractive fruits)) operates to change plants genetically, morphologically, and physiologically. 

When a particle revolves around an axis, a force is developed and acts away from the axis of rotation. This force is called centrifugal force. A particle suspended in a medium takes some time to sediment, which depends upon the size, molecular weight, and viscosity or density of the medium under normal “g” (gravity). To speed up the process of sedimentation, the external field of force is allowed to act on the particle which depends also on the distance of the particle from the axis of rotation in addition to the other factors.

Centrifugation is a technique that promotes accelerated settling of particles in a solid-liquid mixture by the application of centrifugal force. The device that accelerates the separation with the help of centrifugal force is known as ‘Centrifuge’. The centrifuge consists of a fixed base or frame and a rotating part in which the mixture is placed and is then spun at high speed.

Introduction

Out of the total cultivated area of 142 million hectares (M ha) in India during 2011–12, 100.2 M ha was under cereals (the word cereal derives from Ceres, the name of the Roman goddess of harvest and agriculture) and 24.8 M ha under pulses (splitting seed), the staple food grains in the country (Economic Survey 2013). There is very little scope of bringing additional area under food grains; on the contrary this may decline in future due to the land needed for civil amenities and industrial purposes.

Introduction

Cereals are grown over 73% of the total world harvested area and contribute over 60% to the world food production providing dietary fibre, proteins, energy, minerals and vitamins required for human health. Cereals like rice, maize, wheat, barley, sorghum, and oats are chiefly used in the preparation of traditional fermented foods and beverages. However, the nutritional quality of cereals and the sensory properties of their products are sometimes inferior in comparison with dairy products. The reasons behind this the lower protein content, deficiency of certain essential amino acids, the presence of determined anti-nutrients (phytic acid, tanins and polyphenols) and the coarse nature.

Introduction

The cereal cyst nematode, (Heterodera avenae Woll.) a causal organism of ‘molya’ disease in wheat and barley, since after its first report (by Wollenweber, 1924, Vasudeva, 1958 and Prasad et al., 1959), it has been timely reviewed about its spread and losses caused in the various parts of wheat and barley growing areas of the world. It has been reported to occur in Australia, Canada, Israel, South Africa, Japan, in most of the European countries, North America, India, Morocco, Tunisia, Pakistan, Libya, Turkey and Australia (Prasad et al., 1959, Smiley et al., 1994, Rumpen horst et al.,1996, Krall et al., 1999, Nicol, 2002 and Rao et al., 2002). Its economic importance has been assessed by mapping the yield losses caused in cereals i.e. ranged from 15-20% in Pakistan, 40-92% in Sauthi Arabia, 23-50% in Australia (Nicol, 2002) and 40-50% in India (Mathur 1969, Mathur et al., 1980, Handa et al., 1985, Mathur, et al., 1987).

SYNOPSIS

Nature produces plants with healing properties. Hundreds of phytochemicals and antioxidants have been identified in various food plants. Many plants or plant parts are eaten as food. There are several plant species which are cultivated for food, and many have several distinct cultivars. Seeds of plants are a good source of food for animals, including humans, because they contain the nutrients necessary for the plant’s initial growth, including many healthful fats, such as Omega fats. In fact, the majority of foods consumed by human beings are seed-based foods.

Abstract

The frictional properties such as coefficient of friction and angle of repose are very important in designing of storage bins, hoppers, chutes, conveyors, harvesters and threshers etc. Angle of repose is the angle made with the horizontal at which the material will stand when piled. The angle of repose is also important in designing the equipment for mass flow and structures for storage. The static angle of repose (b) was determined using an open-ended cylinder of 150 mm diameter and 250 mm height. The higher the moisture content, the higher the cohesion between the seeds. In terms of flow ability, the seeds are heavier and the inertia to move is increased. Coefficient of internal friction is the frictional resistance of seeds with each other. Coefficient of external friction is the frictional resistance between the seeds and the surface. The rolling resistance is directly proportional to the weight of the rolling object and to the coefficient of rolling resistance which is dependent on the rigidity of the supporting surface and indirectly proportional to the effective radius of the rolling object. The air velocity at which an object remains in a suspended state in a vertical pipe under the action of the air current is called terminal velocity of the object.

Cereal Processing

    1.    The protein content of wheat grain varies widely, but for bread making a value of at least 11% is required.

    2.    Low grain sulphur will result in low concentrations of the sulphur-containing amino acids, cystine and methionine, and may result in poor loaf volume.

    3.    During seed germination endosperm starch is converted into soluble glucose and maltose to support the developing embryo. This is brought about by enzymatic activity, especially the enzyme a-amylase.

    4.    Excessive a-amylase levels result in the formation of a darkened loaf crust as a result of sugar caramelization and a sticky crumb structure which can cause problems during slicing.

    5.    Wheat with a protein level below 10% is preferred to reduce gluten elasticity.

    6.    There is a very good correlation between grain nitrogen and the amount of malt extract achieved, low grain nitrogen giving more fermentable extract

    7.    The term ‘coarse grains milling’ is a very broad one that refers to the comminution of the berries of the wheat, barley and other coarse grain crops.

1. Introduction

The development of food products using composite flour has increased and is attracting much attention from researchers, especially in the production of bakery products and pastries. This article focuses on the use of composite flour to produce food products, namely bread, biscuits, and pasta, with looks at on its impact, following some improvements made, on the sensory quality, rheology characteristics, and nutritional values as well as its overall acceptance. The blending of wheat flour with various sources of tubers, legumes, cereals and fruit flour in different percentages to produce variety of food products are also reported. The positive effects of the use of composite flour can be seen in the final product related to the functional and physicochemical properties and health benefits of raw blended flour along with percentage blending. Overall, composite flour is a good new approach to utilizing uncommon food products as the application of composite flour produced products with different characteristics and quality, depending on the types and percentage of wheat flour used in the formulation.

Bread has been the staple food worldwide and habit of bread is derived in part due to the convenience and wholesomeness. Wheat is a commonly used cereal for making bread as it gives the desired texture due to the presence of gluten forming proteins like gliadins and glutenins (Decock & Cappelle, 2005). In earlier times idea of composite flour in developing countries originated in order to cut down on import of wheat (as it was not grown in many countries) but in recent past refined wheat flour consumption has lead to health issues and thus in order to improve nutritional and functional properties composite flour has been the norm. Composite flour is the one obtained by mixing wheat flour with cereal and legume flours for making bread and biscuits (Dendy, 1992). However, mixing of non-wheat flours, roots and tubers, legumes or other raw materials can also be regarded as composite flour.

Introduction

India is the world’s second largest producer of rice, wheat and other cereals. The important cereals are-wheat, paddy, sorghum (Bajra), barley and maize etc. India is not only the largest producer of cereal as well as the largest exporter of cereal products in the world.

Foodgrain production (2019-20): 296 million tonnes

Importance of Foods

The word “instant” has been used in widely different types of premixes to specify the products either as ready-to-eat food or semi processed foods. The instant premixes available in Indian market were classified as Indian products and Westernized or sophisticated products. The instant mixes included under Indian market products are spice mixes, snack mixes and desert and sweet meat mixes. The Westernized products (instant mixes) contained soup mixes, beverage mixes, desert mixes and soft drink mixes.

Convenience foods are gaining popularity in recent years as they are very easy to handle, require minimum storage space and are attractive. Convenience foods have emerged as a new set of products in the international market. Most of the traditional foods that are commercially available in our country are being prepared / processed by cottage industries and by some of the multinational companies. The various types of convenience foods/ instant mixes that are presently being processed, marketed and consumed all over the country. Supplementation with protein-rich sources and preparation of acceptable ready-to-eat snack foods would not only correct its nutritional inadequacies, but would also provide a variety.

Instant mixes were high in nutritive value especially needed for armed forces, light in weight, easy to carry and prepare. Rapid industrialization and urbanization and changes in eating habits of Indian people led to very high demand for ready-to-use snack foods. The convenience instant foods are meeting the urgent and exigency situations of offering hospitality to unexpected guests.

Changing life styles and values are at the root of considerable changes in eating habits over the last few years. Hand-in-hand with a strong demand for fast and take away foods, there has been a marked upturn in popularity for convenience foods in India. The major reasons for this trend are: the decline of the family meal time, growth in disposal incomes (only in cases of city dwellers), the desire for more leisure time and demand for “foreign” or “sophisticated” dishes inspired by the media and increased travel.

Introduction

About sixty percent of the world’s food intake comes from the three major crops, i.e., wheat, rice and maize (Thielecke and Nugent, 2018). Depending upon the country of utilization and consumption, the products made from cereals such as barley, wheat, maize, triticale, spelt, buckwheat, rice etc. can vary in the range of pasta, bread, pastries, soups, chapatti, cooked rice etc. World cereal utilization in 2021/22 is forecasted at 2,811 million tonnes and the worldwide production of cereals is expected to reach 2,818 million tonnes by 2025 (FAO, 2020).

Cerebrospinal fluid examination is an important diagnostic procedure for evaluating diseases affecting the central nervous system. This chapter describes techniques for CSF collection, including appropriate sampling approaches and precautions. Collected fluid may be submitted for physical, chemical, cytological and microbial examination. Important parameters include colour, turbidity, protein concentration, glucose, chloride, enzymes and nucleated cell counts. Cytological evaluation and culture may assist in identifying inflammatory or infectious processes. Proper sample handling and timely processing are emphasized because cellular and biochemical characteristics can change after collection. CSF findings should be interpreted alongside neurological examination and other diagnostic investigations.

Large Animals The collection and evaluation of cerebrospinal fluid (CSF) in farm animals with signs of diseases of nervous system provides very valuable diagnostic and prognostic information. Routinely, CSF is evaluated for total protein level, erythrocyte and leukocyte counts, and a differential cell count. Additional tests are available for specific neurologic conditions. CSF is primarily produced by the choroid plexuses in the lateral, third, and fourth ventricles through plasma ultra filtration and active transport across the blood-brain barrier. Smaller amounts of CSF are generated by the ependymal lining, pia arachnoid, meningeal blood vessels, and spinal cord’s central canal. The turnover rate is about 1% per minute, meaning systemic electrolyte or acid-base changes take several minutes to affect CSF

Animal body contains several fluids other than blood and lymph which have specialized functions for specific organs. Two of these fluids are cerebrospinal fluid and synovial fluid. The cerebrospinal fluids protects and supports brain and spinal cord function. Synovial fluid protects the functioning of the movement of the body by bone-muscular joints.

Abstract

The drainage pattern and the architecture are the reflections of not only the tectono fabric of a region, but also the active tectonic processes. From amongst many drainage patterns and anomalies, the eyed drainages, deflected drainages and the compressed meanders interpreted from satellite images for Pudukkottai region of Southern Tamil Nadu infer to reflect the active N-S block faults and NE-SW sinistral and NW-SE dextral faults related to post collision tectonic phenomena.

Introduction

The Geoscientists have long back recognized that the drainages are the reflections of the surface and subsurface lithology, structure and tectano fabric and also the active tectonic movements especially of the Quaternary period (Thornbury, 1985). Hence, the Geoscientists have all along been showing greater interest in mapping the drainage patterns. However, the mapping of the drainage patterns and detection of tectonic features there from have gained greater momentum only after the advent of modern Remote Sensing technology. Since the airborne and satellite borne spectral images have the credentials of showing the drainage pattern, the drainage anomalies and the tectonic features related to them all of which were studied in conjunction to bring out information on the geological history of the Quaternary period by many workers (Vaidyanadhan, 1971; Murthy and Sastri, 1981; Agarwal and Mitra, 1991; Ramasamy, 1991; Saravanavel and Ramasamy, 2014).

Abstract

The strenuous field trekking, inaccessibility, perception of geology only within the visibility range of the eyes etc. have remained matters of major constraints in the past in field based geological mapping. The remote sensing technology not only eradicated these but also provided lot many newer vistas in the field of geology. In addition, the application of such unique technology has brought out a hierarchy of newer concepts in the field of geology. The paper narrates the newer knowledge gathered on the geology of South India in the post remote sensing Era.

Abstract

As the available surface water is too inadequate to fulfill the man’s requirements he was forced to locate newer groundwater reservoirs on one side and to control the fast depleting water table on the other side. As the ancient techniques have failed to give precise models on groundwater targeting, he was to invent and employ newer technologies. Under this scenario the recently invented spatial technology has emerged as a very powerful tool in groundwater targeting and management. The vistas and virtues of such spatial technology in groundwater management have been discussed in this overview paper by citing some case studies from Tamil Nadu, India.

Certification and adherence to quality standards are essential for ensuring the authenticity, safety, and marketability of natural bee products such as honey, beeswax, propolis, royal jelly, and pollen. These standards are especially important in the expanding natural and organic product sectors, where consumer trust and product integrity are critical. Certification validates that bee products are produced using specific methods aligned with natural or organic farming principles—free from synthetic chemicals, pesticides, and artificial additives.

Certified natural bee products often command higher prices and gain access to premium domestic and international markets. Key quality parameters include moisture content, sugar composition, absence of adulterants, pesticide residues, and microbiological safety. Regulatory authorities such as the Food Safety and Standards Authority of India (FSSAI) conduct assessments and enforce compliance with these criteria. For instance, honey is evaluated for HMF levels, diastase activity, and pollen count, while beeswax and propolis are tested for chemical contaminants.

Certification not only promotes sustainable and ethical beekeeping practices but also supports biodiversity conservation and traceable trade systems. Consumers benefit through guaranteed product safety and health advantages, while producers gain market credibility and economic incentives. However, small-scale beekeepers often face obstacles such as high certification costs and complex documentation. Supportive measures like training, capacity-building, and technological innovations— such as blockchain for traceability—can help expand certification accessibility and improve transparency throughout the value chain.

JAIVIK BHARAT, FSSAI, AGMARK FOR HONEY
India’s organic food market, including honey and other bee products, is expanding rapidly, necessitating mechanisms to guarantee product authenticity and consumer trust. In this context, Jaivik Bharat, AGMARK, and FSSAI serve distinct but complementary roles in regulating and certifying organic and quality food products.

Need for certification

Forest restoration and reforestation experts know the effect the right seed source can have on the long-term economic and ecological success of tree planting efforts. However, unlike stock quality (such as size and health), genetic quality (seed source) cannot be observed by the consumer at the time of stock purchase. Where once the provincial government controlled the source of seed and its destination through the provincial nursery system, seed supply is now in the private sector, and the source is unknown or a matter of trust. Tree planting in general needs help, and the wrong seed source is only one of the many reasons that your planting project may not be successful. Besides, the identity of the source will be tracked throughout the chain of custody until it is presented, as a labeled, certified product to the consumer. The seed source may be from a single parent tree or preferably from a large healthy stand of trees. But if seed is bulked from many locations, the label on the resulting seedlings can only indicate the greater area. For example if a nursery bulked its seed from many counties across a specific place, they can only certify and market that crop as? specific place? not as one from a specific county that may have been a source for the seed. For this reason we will have to encourage collectors and growers to bulk only by tree seed zones to promote certification program for the context of successful tree planting.

Natural farming in India is increasingly being recognized not just for its ecological integrity but also for its potential to enhance farmer incomes through systematic certification, innovative marketing, and value-added processing. Together, these elements form a vital support framework for scaling natural farming as a sustainable livelihood model.
While natural farming is rooted in chemical-free traditional practices, certification mechanisms like the Participatory Guarantee System (PGS) and thirdparty organic certifications provide formal recognition. These certifications— backed by government agencies and NGOs—enhance credibility, assure consumers of product authenticity, and allow farmers to label their produce as
natural or organic. This certification enables access to niche, premium markets where consumers are willing to pay more for sustainable and safe food options.
Marketing remains a key challenge but also a promising frontier. Traditional supply chains often fail to acknowledge the ecological value of natural produce. Direct-to-consumer sales, farmers’ markets, and online platforms like Jaivik Kheti are bridging this gap, offering better price realization. Farmer Producer Organizations (FPOs) further strengthen the position of natural farmers by enabling bulk marketing, logistics management, and improved price negotiation.
Value addition transforms raw produce into market-ready goods such as  pickles, flours, oils, and herbal teas, significantly enhancing profitability. These products appeal to health-conscious consumers and often command premium prices. Many on-farm processing units are run by rural women’s self-help groups, thereby creating jobs and empowering local communities.

Biodynamic farming, a holistic approach to agriculture pioneered by Rudolf Steiner, integrates ecological principles, cosmic rhythms, and spiritual practices into farming methods. While it offers numerous environmental and ethical benefits, biodynamic farming also faces various challenges and criticisms. This article examines the key challenges and criticisms associated with biodynamic farming, including scientific skepticism, economic feasibility, practical implementation issues, and market acceptance. Through a detailed analysis of these aspects, the article aims to provide a comprehensive understanding of the limitations and contentious aspects of biodynamic farming, offering insights into potential areas for improvement and future research.

Technical and Economic Challenges in Advanced Packaging The implementation of advanced packaging technologies comes with a range of challenges. Technically, developing materials that are both highly effective and environmentally friendly is a complex task. Packaging must not only protect products and ensure their safety, but also minimize its ecological footprint. From an economic perspective, these advanced solutions tend to be more expensive, which can make it difficult for smaller businesses or those in cost-sensitive markets to adopt them on a large scale. Furthermore, the need for efficient production methods, scalable new materials, and affordable solutions continues to be a significant hurdle for the industry. Balancing Performance with Environmental Goals One of the primary challenges in packaging is achieving

Poultry sector is expected to play the most crucial role in transforming the nutritional demography of country with ever growing share of protein based cheap human diets. Some of the specific challenges the poultry sector is faced with are as follows:
a) Regional imbalances in poultry production
The commercial layer farming is yet to make a dent in some of the region of country. However, broiler farming is gradually catching up in majority region.
b) Underexploited poultry diversity
Among poultry species, chicken production has already acquired large scale commercial dimensions in some states due to its better efficiency. However, there is a scope for exploitation of other domesticated poultry species.
c) Rising feed cost
The growth in poultry has outpaced the growth in cereal production leading to severe feed shortages and consequent rise in feed cost. Cereal by-products and oilseed residues usually constitute more than 80 percent of poultry diet. Coarse cereals also form the staple diet of millions of marginal farmers and landless labourers. These coarse cereals are the most important and most widely used poultry feed ingredients all over the world. The demand for coarse cereals is continuously increasing at 4 percent per year due to ever increasing population and their use in livestock rations.

The present publication has highlighted the issues on different aspects of food sector expressed by very distinguished authors. The issues have been discussed and illustrated how we conceive food as an item, what and how much food is known to consumers, what are common food sources, the relationship between food and health, food and nutrition security programmes in different regions of the world and how do we perceive food and nutrition policy challenges?

India’s agriculture, a foundational pillar of its economy, boasts a rich history dating back to the Indus Valley Civilization. Despite employing 40% of the workforce and achieving global leadership in commodities like spices, pulses, and milk, agriculture’s GDP contribution has declined to 15-18%. Challenges such as price volatility, climate change, trade barriers, and infrastructure deficits hinder the sector’s global competitiveness. However, opportunities abound in agri-tech innovations, organic farming, and expanding exports of high-value products like basmati rice and Alphonso mangoes. Strategic policy reform, sustainable practices, and investment in infrastructure and technology can position India as a global agricultural powerhouse.

India has a wide agroclimatic range i.e. temperate, subtropical and tropical, enabling to achieve horticulture diversification. India is second in fruit and vegetable production at global level. The percentage share of horticulture output in agriculture has become 33%, (Horti statistics, 2018). However, productivity in most of the horticulture commodities is very low below world productivity, as we have not concentrated intensively on some major aspects to achieve competitiveness in horticulture for expansion in international trade.

India has potential to lead the world in horticulture. Horticulture is mostly concerned in different aspects of human beings such as provision of nutritious food to achieve a balanced diet; rural employment, integral part of rainfed and dry land areas, wealth generation through the activities of production, processing, marketing, servicing, and related sectors, economically important in export related activities and associated with all the elements of the supply chain etc. 

10.1. Challenges and Opportunities in SMEs

The Nigerian transport system faces great challenges and also offers several opportunities. The predisposing factors include:

• The size of the country: With area coverage of 923,768.64 km2, spanning longitude 30E-160E and latitude 40N-140N Nigeria is a comparatively large country. It is inhabited by over 140 million people. Transportation is a crucial instrument for linking the country economically, socially and politically.

• Nigeria’s vast natural resources: Nigeria is endowed with petroleum, gas and solid mineral resources. The country is also blessed with abundant agricultural and forest resources, which vary by the three ecological zones of the country. The country is endowed with a highly productive open sea with abundant and diverse marine resources within her coastline of 852km bordering the Atlantic Ocean in the Gulf of Guinea and her maritime area of 46,000 km. This variation is a factor in spatial interdependence. Transport plays an important role in the exploitation and distribution of these resources and in the reduction of spatial inequality and in poverty alleviation.

During the last 50 years or so, the world has witnessed tremendous changes in terms of population exodus, accessibility to food, advancement in agricultural science and technology, increased food production, efforts in mitigating food and nutrition security, natural and human made disasters and developmental efforts in handling and containing national and global issues. Inspite of these efforts, the challenges which have cropped up are plenty and at the same time creating avenues of opportunities to address those challenges in the interest of humanity. The world is large, countries are many, agro- climatic regions vary significantly, socio-economic conditions are distinct and the national, regional and global issues vary greatly. For ease of presentation and convenience of illustration, common issues only will be dealt in this chapter. Keeping in view the theme of this book, the following topics/issues will be discussed which pose challenges for the living humanity and for future generation within next 50 years. The views are limited to developmental, planning and implementation processes only in order for governments and others to consider overcoming these challenges.

18.1 Introduction

Unpacking the rural landscape having various challenges due to its complex and composite nature.

The development of successful plans and policies requires an awareness of the following issues.

18.1.1 Heterogeneity of Rural Areas

Rural landscapes are diverse, exhibiting variations in geography, culture, and economic activities. Addressing the unique needs of different regions requires a modulation approach (Cloke & Milbourne, 1992). Different topographies, such as hills and plains, have an effect on farming practices. Economic heterogeneity results from the use of various farming techniques and the presence of various sectors. Socially, these locations are characterised by diverse ethnic groups with a diversity of cultures. Access to healthcare and education is restricted by inequalities in infrastructure and services, which add to the uneven development.

Introduction
Liposomal drug delivery methods have received a lot of interest in the pharmaceutical industry because of their capacity to improve therapeutic efficacy while also reducing toxicity of encapsulated pharmaceuticals. Liposomes, which are spherical vesicles made up of lipid bilayers, provide targeted delivery of drugs, increased bioavailability, and controlled release of therapeutics (Gupta et al., 2023; Rana et al., 2023; Salave et al., 2023, 2024). However, guaranteeing the sterility of liposomal formulations is critical for their safety and efficacy, particularly in parenteral applications.
Sterilization is a validated process that achieves a microorganism-free product without altering its properties. In the pharmaceutical industry, a sterilization process is deemed valid when it successfully attains the necessary Sterility Assurance Level (SAL) of 10-6. The SAL represents the likelihood of contamination occurring after the sterilization process for a product with an initial biological load of 106 colonyforming units (Woedtke et al., 2008). The biological indicator used in this case is one of three bacterial species: Geobacillus stearothermophilus, Bacillus pumilus, or B. atrophaeus (Mcevoy et al., 2023). Accordingly, a product may be deemed “sterile” if the likelihood of a viable microorganism being present is equal to or less than 106. Liposomal formulations provide particular issues for sterilization due to their fragile nature and the physicochemical features of the encapsulated drugs. Sterilization plays a vital role in the production of liposomal formulations for parenteral administration. It is crucial to remove all viable microorganisms to prevent infections, maintain the effectiveness of therapeutic agents, and ensure patient safety. The delicate nature of liposomal carriers presents unique challenges in the sterilization process (Lombardo et al., 2022 a).
Traditional sterilization methods, such as autoclaving, dry heat, and chemical sterilization, are frequently not suitable for liposomal structures (Figure 1). The application of these techniques can lead to the breakdown of lipids, changes in phase, or destabilization of the drug contained within the formulation, resulting in a decrease in its therapeutic effectiveness (Zuidam et al., 1993 a). In addition, the physicochemical properties of liposomes, such as their size, lamellarity, and lipid composition, play a crucial role in determining their stability and how they react to sterilization methods.
Considering these limitations, the pharmaceutical industry has investigated alternative methods of sterilization that guarantee the elimination of microorganisms while preserving the integrity of liposomes. A commonly used method for sterilizing liposomal formulations is filtration through sterile membrane filters with pore sizes of 0.2 micrometers (Goldbach et al., 1995 a). This

13.1 Challenges in the technology transfer process
Technology transfer (TT) is more complex and involves the complex interrelationships between universities, research institutes, the private sector, the state, and society. Though TT is all about translating research findings into purposeful solutions that can support the economy and society, it is not a linear process. The challenges can be described as legal, institutional, cultural, financial, policy, and human resource. All this is accompanied by bottlenecks that inhibit or decelerate the diffusion of promising technologies.
13.1.1 Legal and intellectual property challenges
The vital component of technology transfer is the proper management of intellectual property (IP), which is often the most challenging aspect.
• Ambiguities in IP ownership: During multi-institutional or shared funder research, ownership is quite controversial. As an example, when a government lab and a university collaborate on the project, there is ambiguity as to who would have the ultimate licensing authority over the technology: the university, the lab, or the funding agency. This kind of fight hinders commercialisation and scares off industry partners.
• Lengthy patent filing and prosecution timelines: In several jurisdictions, the filings, examination, and granting of a patent may take between three and five years or more. Such delay is not compatible with the rapid cycle of invention in other fields such as ICT or biotechnology, where patent claims may become invalid before they are granted.
• High costs of IP protection: International direct patenting, like under the Patent Cooperation Treaty (PCT), is costly and involves legal services, fees, and upkeep costs. These costs are excessively high, which cannot be easily compensated by universities and startups, and where technologies are not secured or limited to local markets.

Definitions: Before starting the chapter, it is better to understand the basic definitions of the terms commonly used in this chapter.

Waste: Waste is any material or object which is discarded after its primary use by its holder. A holder means the person who produces and keeps the waste. 

Abstract

India today has 1.30 billion people and would be the world’s most populous country by 2025. The challenge is how to feed India’s growing population with rising income, but limited land and water resources. Whereas area under crop cultivation has come down from 142 million ha to 138 million ha, asking for protecting the arable lands from mass urbanization and more productivity per unit area. The agricultural production systems are still operating at low productivity and high uncertainty in the country. There is little or no alignment between production, the growth of agricultural commodities in the market and the supply of these commodities. All this leading to considerable farm produce wastage, mounting tremendous pressure on natural resources and would pose a challenge to the country in providing food, water, health, shelter, sanitation and jobs to all.

While industry and services have grown, agricultural sector has lagged behind. Information technology sector is growing consistently at 30 per cent every year but agriculture has not even achieved 4 per cent growth. The contribution of agricultural sector to national Gross Domestic Product (GDP) has continued to decline over the years; has shrunk from 55 per cent in 1951-52 to 14.6 per cent in 2015-16. Land fragmentation, reducing holding size, obscure marketing prospects, low water and inputs use efficiencies, modest level of mechanization, unorganization, unreliable returns from rainfed areas, inadequate storage infrastructure, weak processing sector and meagre investments continue to leave visible impressions on Indian agriculture. Nonetheless, agriculture remains a major source of employment, absorbing about 52 per cent of the total national workforce. Higher levels of investments in agriculture, both by the public and private sector can yield much better results if the reforms are undertaken to streamline not only the incentive structures for the farmers, but also the institutional framework to address the issues of integration, export orientation, infrastructure development, and information technology and management to achieve the objective of a innovative agricultural sector capable of providing food security to all. Farmer insecurity about crop failure also prevents them from adopting changes. A balance between risk and reward is considered to be an important economic factor for enhancing relationships. Trust among channel partners, power share and interdependence are other important factors for enhancing relationships in the supply chain system.

ABSTRACT

Dairy farming plays a significant role in rural economy. It provides more avenues for increasing rural incomes and sustaining livelihood. Milk and other dairy products are a major source of protein and calcium for vast vegetarian population of India and demand is likely to double within a decade. Many of the educated youth in rural areas are going back to dairy farming as a natural choice with passion, getting involved deeply, continuously learning and innovating in the process. However these young and intuitive farmers face many challenges especially with regard to technical input and availability of green fodder round the year. In order to address these problems, this study was conducted in Muktsar district of Punjab. The young farmers selected belong to age group ranging from 24-35 years. Seventy percent of the respondents were graduates, among them 25 percent being technocrats. About 65 percent had medium family size (5 members). Eighty five percent of respondents had small land holding ranging from 5-8 acres. For majority of the respondents’ dairy was the primary occupation. Sixty percent of the respondents had obtained 45 day artificial insemination (AI) training from Dairy Development Board, Punjab and themselves did AI on their farm. Many (75 percent) had herd size of 35-40 animals. Majority of the farmers had hired labour for milking and daily care of animals with family members involved in management of the farm. Most of them (65 percent) believed in preparing their own silage and breed improvement. The study revealed that many educated youth in dairy farming were of progressive and scientific temper with entrepreneurship potential but were facing many impediments like low milk yield (4.5 – 6.5 kg/ animal/day), poor breed up gradation, green fodder shortage, a large number of services per conception (3 in majority cases) with artificial insemination (AI), low competence of veterinary service providers in remote rural areas in addition to high veterinary costs, difficulty in marketing milk from crossbred dairy cows due to low preference. It was felt that if sincere and sustained efforts were made by all the stakeholders involved, dairy farming had the potential for all round socio-economic development of rural areas.

Introduction

India has one of the world’s largest agricultural production areas of land. The net sown area is 140.1 million hectares, the net irrigated area is 49% of this, which is 68.4 million ha as per 2014–15 land-use statistics (Agriculture Research Data Book 2019). While the proportion of Indians employed in agriculture is decreasing, agriculture, along with its allied sectors such as livestock, forestry and fisheries, remains India’s primary source of income. As per the Lok Sabha Standing Committee on Agriculture (2019–20), agriculture and allied industries employed 54.6 percent of India’s total workforce. Approximately 70% of rural households still rely primarily on agriculture for a living. Agriculture and allied sectors’ share of the country’s Gross Value Added (the value of goods and services produced in an area, industry, or sector of an economy) has fallen from 18.2 percent in 2014-15 to 16.5 percent in 2019-20. As per current trends, 60% of India’s population (more than 10% of the world’s population) will face severe food shortages by 2050.

ABSTRACT

Agriculture and allied sectors is the largest livelihood providers in rural India, still Indian farmers are among the poorest in the World. Agriculture sector is potentially largest employment providing sectors in the country. Despite this, unemployment is high among educated rural youth, and they prefer to migrate to urban areas to take up low paying jobs. The present study was carried out mainly to find out the challenges faced by rural youth in choice of agriculture as a means of livelihood. The study was conducted in four villages in Udham Singh Nagar district in Uttarakhand. Data was collected from 115 youth using pre-tested interview schedule. It was found that maximum number of respondents had education up to higher secondary level, majority were students and had medium level of mass media exposure and change proneness. The study indicates that limited access to new agricultural technologies, limited access to farm machinery, perception regarding suitability to agriculture, damage of crops from pests and insects, and lack of information on agricultural inputs and government policies were the main challenges faced by rural youth in choosing agriculture as a means of livelihood. The study indicates that government has developed policy framework for involving youth in agriculture. This study can be carried on training needs of youth in agriculture and allied sectors.

1. Introduction

India is a land of great diversities in terms of people, culture, languages and the style of living, among many other varied characteristics in the country. Based on the climatic, geographical, and cultural features, the country is broadly divided into six zones - the Northern, Southern, Eastern, Western zone, Central and the North-Eastern zone. Eastern zone comprises Bihar, Jharkhand, West Bengal, Odisha, Chhattisgarh, Assam and eastern UP (27districts of UP). This document exclusively focuses on the four states namely Bihar, Jharkhand, Odisha and West Bengal in the Eastern Zone with an attempt to look into the bottlenecks inhibiting the rural development of the zone.The f inancial institutions for agriculture in India was developed with the purpose of financing the needy farmers and providing them the facilities to increase the efficiency of agriculture. As a result, NABARD was formed in 1982. Thus, it was developed as an apex bank to help and support the agriculture section in India.This chapter seeks to evaluate the role of various financial institutions which play a major role in raising the standard of living of nearly one-fourth of India’s population in the eastern region of our vast country.

Dryland agriculture limits the crop growth to a part of the year due to lack of sufficient moisture (Peterson et al., 2006). According to the Fourth five-year plan of India, dry lands are defined as areas which receive rainfall ranging from 375 mm to 1125 mm and with very limited irrigation facilities. Dry lands are economically fragile regions which are highly vulnerable to environmental stress and shocks. Degraded soils with low water holding capacities along with multiple nutrient deficiencies and depleting ground water table contribute to low crop yields and further leading to land degradation. In a country like India, 44 per cent of the total food production is supported by dryland agriculture, thereby playing a critical role in nation’s food security. With the increasing population, food production has to be increased. A real need to second green revolution has been envisioned, which can be achieved by improving the dryland agriculture.

Introduction
The accurate identification of crop varieties is crucial for agriculture, plant breeding, and intellectual property protection. DNA-based techniques have emerged as powerful tools for distinguishing between crop varieties due to their precision and reliability. However, several challenges persist in the adoption and implementation of these techniques. Conventionally, morphological descriptors are routinely used for establishing the identity of varieties. But these morphological descriptors suffer from many drawbacks such as influence of environment on trait expression, epistatic interactions, pleiotrophic effects etc. Furthermore, the paucity of sufficient number of these descriptors for unequivocal identification of increasing number of reference collection of varieties enforces to look for alternatives. Electrophoresis of seed proteins and isozyme analysis have overcome these limitations to some extent but now many powerful DNA based techniques are available. Since all genetic differences between individuals are laid down in the primary sequence of their genomic DNA, the straightforward method of identification of crop varieties and parental lines would be to determine this sequence for the genome under comparison. Sequencing requires huge monitory investment and it is practically impossible to sequence the whole genomes of all varieties. But with the automation in sequencing now possible, short stretches of amplified DNA can be sequenced. However, a more practical strategy would be to limit the comparisons to specific regions of the genome, which frequently differ between individuals.

Food safety scientifically describes various methods of handling, preparation and storage of food to prevent any foodborne illnesses. However, it is important to check the safety between industry, market and the consumer. From the food industry to the market the practices relating to food labeling, food hygiene, food additives and pesticide residues are important to be looked into and the policies on biotechnology. The governmental imports and exports needs to be given proper guidelines. Certification systems and Inspection for foods need to be installed which should be clean and corruption free. When all this is properly considered the food could be safe in the market. This may allow for safe delivery and safe preparation of the food for the consumers. Many diseases are transmitted by food which serves as a growth medium for bacteria and cause food poisoning. In the developed countries it has been observed that there are many intricate standards for food preparation. However, in the developing countries the availability of adequate safe water itself is a question. It is possible to prevent food poisoning to 100%. An ordinance and code regulation in US (1943)was given.

There are several difficulties involved with consuming and storing microgreens. Addressing low shelf life and putting into practice efficient postharvest management for microgreens provide formidable challenges for researchers. It's critical to comprehend any relationships that might exist between spoiling and human pathogen contamination. Research has indicated that microgreens including basil, lettuce, parsley, melons, and spinach can have infections from pathogens during the seed-to-harvest stage (Alegbeleye et al., 2018). Growing environments that support the growth or transfer of microorganisms, processing techniques that expose the crop to contaminants from people or animals, and physiological traits of the plant that facilitate contact and binding with microorganisms are some of the factors that contribute to this risk (Maluin et al., 2021). Because external fertilizers and manures are applied sparingly, there is little contamination even though microgreens are protected from pests and insects by controlled surroundings.

ABSTRACT

World is suffering from coronavirus infection since the end of 2019. Corona virus disease spraying rapidly throughout the world from the beginning of 2020, for that cause it is declared as pandemic by WHO in march 2020. As no proper remedy found for this particular new disease till the date it is become oblivious to maintain social distancing and lock down. Due to the situation each and every sector including the education system totally stopped from March 2020. But we have to maintain the flow of education. Many of the educational institution of India promoted e learning for their students. To avoid coronavirus infection social contact as well as to carry out classes in regular manner, it is become necessary to promote e learning everywhere. But in India the situation is different because Steel we are a poor country where a good number of people do not have a smart phone even. There are many challenges in promotion of e-Learning during this coronavirus pandemic situation in India. In present paper we are going to discuss about some challenges in promotion of e-learning due to coronavirus pandemic situation.
