A DSLR, or “Digital Single Lens Reflex” camera, uses a mirror mechanism to direct light from the lens to an optical viewfinder, allowing the photographer to see exactly what the lens sees. When the shutter is activated, the mirror moves aside, allowing light to reach the image sensor, capturing the photograph. While single-lens reflex cameras have been around in various forms since the 19th century, initially relying on film, the first commercially available digital SLR with an image sensor emerged in 1991. Unlike point-and-shoot or phone cameras, DSLR cameras allow for interchangeable lenses, offering greater
flexibility.
Working Principles of DSLR Camera
When using a DSLR camera, the image seen through the viewfinder at the back of the camera is the actual view through the lens. This ensures you are previewing the precise scene you intend to capture. Light from the scene enters through the lens and hits a reflex mirror positioned at a 45-degree angle inside the camera. This mirror directs the light vertically to an optical component known as a “pentaprism.” The pent prism then reorients the light horizontally by passing it through two internal mirrors, delivering the final image into the viewfinder.

In Individual Contact Method, the extension agent engages with individuals on a one-on-one basis, ensuring personalized interaction with each person. This method is employed when the target audience is limited in number, geographically proximate to the communicator, and ample time is allocated for effective communication.

Farm and Home Visit

This method entails direct, face-to-face interactions between extension agents and farmers, typically conducted either on the farm or at the farmer's residence. Its objectives include providing firsthand information on agricultural and household matters, assisting farmers in problem-solving, and aiding in their livelihood sustainability.

Techniques

• Planning and Preparation:

• Identify target audience and topics of discussion.

• Gather relevant materials and publications.

• Schedule visits efficiently and provide advance notice to farmers.

Cities or urban conglomerations are fast developing and where the rate of land availability has infinitesimally small; vertical expansion and taller buildings have emerged and are defining the city skyline. Though this may speak well of the economic development, but the increase in hard paved areas and roads may spell trouble for the environment as urban heat island (UHI) effect. The causes of Urban Heat Island are primarily due to the absorption of solar radiation (Short wave) by building/urban materials that is subsequently re-radiated (long wave) to the surroundings. In addition, heat generated from the use of air- conditioning coupled with the greenhouse effect of pollutants also contribute to the increase in temperature. Such increase in temperature with the presence of air pollutants can result in the accumulation of smog, damages the natural environment and jeopardizes human health. It also costs consumers more money because it takes more energy to cool buildings. Who can forget the regular news of Beijing repeatedly topping the list of most polluted cities and fresh air is available in cans!

Fresh air cans are in no means a firm solution. Plants are atmosphere cleansers, can serve to filter carbon dioxide and other toxins in environment, cool the air by transpiration and also provide cooling shade. Research work shows the benefits of using light colour roofs and roof gardens to minimize the heat gain inside the buildings. This would in turn reduce the energy consumption of air conditioning in buildings. Rooftops, balconies and terraces have often been referred to as the “last urban frontier” of cities, in the sense that they represent the last significant remaining space to be exploited to create a green oasis and an area of relative peace and privacy away from the urban bustle. Given the social, economic and environmental contributions of urban greenery to the quality of life in cities and the realization that cities more often than not lack sufficient greenery, greening of rooftops, balconies and terraces is therefore a logical, effective and high impact way to re-inject the much needed greenery in urban settings thus reinventing the concept of hanging gardens.

Hantaviruses have been responsible for a variety of human illnesses particularly haemorrhagic fever with renal syndrome (HFRS) and hantavirus pulmonary syndrome (HPS). There are currently 47 recognized sero/genotypes of hantaviruses with considerable geographic diversity. Each hantavirus type appears to be specific to a different rodent host. The different hantavirus types are associated with different types of disease both in terms of target organs and disease severity. HFRS is primarily a disease of the Old World while HPS is a disease of New World. Although the disease may have first been recognized as early as 1000 years ago in China, it affected >3000 United Nations Soldiers during Korean war (1950-1953). Now it is reported that hantavirus affect as many as 2 lakhs people each year in Asia and Europe. The agent of this virus remained unknown until 1978 when Lee and his associates isolated and named Hantaan virus, after a river in South Korea. Other viruses antigenically related to Hantaan virus were characterized and placed under the genus Hantavirus and family Bunyaviridae.

Over the past few decades, the sharp increase of incidences of hantavirus disease in humans throughout the world has been reported. There are 47 recognized hantaviruses with considerable geographic diversity. But the number of hantavirus virus types recognized continues to grow. Hantaviruses cause persistent infections in rodent reservoirs which directly impact transmission of these zoonotic agents between rodents and from rodents to humans. Environmental, 127 demographic and physiological factors likely interact to mediate responses to hantaviruses in natural rodent populations. Although not much work has been carried out, comparisons of human and rodent immune responses to hantaviruses may provide insights into why hantaviruses often are fatal for humans but cause only persistent infections in rodents.

Hard currency : Money you can trust. A hard currency is expected to retain its value, or even benefit from appreciation, against softer currencies. This makes it a popular choice for people involved in international transactions. The dollar, d-mark, sterling and the Swiss franc each became a hard currency, if only some of the time, during the 20th century.

Hawala : An ancient system of moving money based on trust. It predates western bank practices. Although it is now more associated with the Middle East, a version of hawala existed in China in the second half of the Tang dynasty (618-907), known as fei qian, or flying money. In hawala, no money moves physically between locations; nowadays it is transferred by means of a telephone call or fax between dealers in different countries. No legal contracts are involved, and recipients are given only a code number or simple token, such as a low-value banknote torn in half, to prove that money is due. Over time, transactions in opposite directions cancel each other out, so physical movement is minimised. Trust is the only capital that the dealers have. With it, the users of hawala have a worldwide money-transmission service that is cheap, fast and free of bureaucracy. From a government’s point of view, however, informal money networks are threatening, since they lie outside official channels that are regulated and taxed. They fear they are used by criminals, including terrorists. Although this is probably true, by far the main users of hawala networks are overseas workers, who do not trust official money transfer methods or cannot afford them, remitting earnings to their families.

Family: Ixodidae (Hard ticks)

General characters

•These ticks have hard chitinous shield called scutum on their dorsal surface, so they are called hard ticks. Scutum extends over the entire dorsal surface in male and only anterior one-third of dorsal surface in larvae, nymph and female.

 •Mouth parts are anterior and visible from dorsal aspect.

 •Eyes are one pair (if present) situated on the lateral margin of scutum.

•Spiracles are one pair and situated posterolaterally to the fourth coxae. 

 •Basis capituli or capitulum present at anterior, and have mouthparts and palps.

•The body of female may have one pair marginal grooves at lateral side of behind the scutum.

Plant tissue culture is mainly referred to as mass-multiplication of in vitro derived plantlets grown under controlled environment. Subsequently, the production of artificial seeds from in vitro grown plant propagules is also a method of mass-production of true-to-type plantlets. Micropropagation allows rapid and mass production of high quality, disease free and uniform planting material irrespective of the season and weather. Micro-shoots on being transferred to ex vitro conditions are exposed to abiotic (altered temperature, light intensity and humidity conditions) and biotic stress conditions i.e. soil micro-flora, so there is need for acclimatization for successful establishment and survival of plantlets (Deb and Imchen, 2010). In order to increase growth and reduce mortality in plantlets at the acclimatisation stage, research has been focused on the control of the environmental conditions (both physical and chemical) and to acclimatize the plants to compete with soil microflora (Mathur et al., 2008). In this chapter methods of acclimatization of plantlets derived from simple plant tissue culture or from synthetic seeds are discussed.

The ultimate success of commercial propagation depends on the capacity to transfer plants out of culture on a huge range, at low cost and with high survival rates. The plants multiplied in vitro are exposed to a unique set of growth conditions (high levels of inorganic and organic nutrients, growth regulators, sucrose as carbon source, high humidity, low light, poor gaseous exchange) which may support rapid growth and multiplication but also induce structural and physiological abnormalities in the plants, rendering them unfit for survival under in vivo conditions. Poor control of water loss and heterotrophic mode of nutrition are main cause of deficient growth of in vitro plants.  Hence, gradual acclimatization is necessary for these plants to survive transition from culture to the greenhouse or field. During acclimatization the in vitro formed leaves do not recover but the plant develops normal leaves and functional roots. Once roots are well formed the plants are ready to be transferred into soil.The procedure of acclimatization of regenerated plantlets are: 

Introduction

In a technology that consistently maintains a fantastic development curve with capabilities doubling up year-to-year, freezing the hardware specification is not easy or very meaningful. GIS (not geography) owes to its genesis and progress to the developments in information technology front. It may be asserted that any and all upgrade in the hardware industry will only add to its own ability to effectively process more and more data and handle more complex routines. The personal computers of today are seen to be adequate to run typical GIS software. A reference hardware specification is discussed here. GIS software development is an involved process but then the software developers have made good use of hardware capabilities available and have released upgrades consistently. Hardware developments are such that they defy a static spcification. However a reference specification as on 2009. An overview of various software packages used in the past as well as present is attempted. ESRI released a new version in 2002 and claimed that their ArcGIS is an “integrated collection of GIS software products for building a complete GIS that enable users to deploy GIS functionality wherever it is needed, in desktops, servers, or custom applications; over the Web; or in the field.” The details are discussed below. While a number of software overviews are available, this text is not aimed at providing a tutorial to any of the software packages nor do the comparisons made are to promote any particular software. Similarly, it is presumed that the reader is familiar with the hardware elements and functionality. Lot of information about the software packages are available on their respective web sites and the reader is exhorted to look for current, additional and in depth information required in the pages. A brief discussion on Liveware or human resource can be found at the end of the chapter.

In a large random-mating population both gene frequencies and genotype frequencies remain constant from generation to generation in absence of migration, mutation and selection and the genotype frequencies are determined by the gene frequencies. These properties of a random mating population were first explained by G. H. Hardy and W. Weinberg independently in the year 1908 and are generally known as Hardy-Weinberg law. The operational understanding of this law involves three steps as follows:

1. From parents to the gametes they produce.
2. From union of the gametes to the genotypes in zygotes produced.
3. From genotypes of the zygotes to the gene frequencies in the progeny generation.

The gene and genotype frequencies in the original parent generation are assumed as follows:

Pesticides can cause three types of harmful effects – Acute, Delayed and Allergic.

Acute effects: Are those that occur immediately after the exposure, within minutes or hours.

Weeds interfere with man’s utilization of land and water in various ways. The extent of losses depends on the intensity, infestation, time of occurance and type of weeds.

1. Competition between weeds and crops for growth factors

Weeds compete with crop plants for  other factors in the micro-enviroment. Weeds are capable of absorbing more amount of nutrient from soil than the crop plants. In dry lands, weeds exhaust the soil moisture and put the crop under water stress earlier and thus reduce the yield. Weed can compete with productive crop or pasture land or convert the productive land into unusable scrub. Weeds are also often poisonous, produce burrs, thorn or other damaging body parts or otherwise interfere with the use and managemet of desirable plants by contaminating  harvest or excluding livestock.

Introduction

Resource management balances human needs with environmental preservation, focusing on sustainable development, responsible use, and conservation of natural resources. It involves environmental stewardship, economic efficiency, and social equity, ensuring equitable access for all societal segments while meeting present and future demands (Study Smarter, N.D; Mohd Akhter Ali et al., 2023).

There are specific areas such as water, soil, forests, waste, and sustainable harvesting practices. Each area presents unique challenges and opportunities, requiring tailored strategies and interventions to promote sustainability. The interplay between human activities, environmental impacts, and socio economic dynamics through the lens of resource management highlights the need for sustainable practices that balance development with ecological preservation, ensuring equitable resource distribution and long-term economic stability. Emphasis is placed on holistic approaches, participatory decision making, and capacity building to enhance resource governance and promote sustainable practices.

Introduction

In the face of a growing global population and increasing pressures on natural resources, the quest for sustainable and efficient agricultural practices has become highly significant. The integration of livestock with cropping systems and grasslands stands out as a holistic approach that not only addresses these pressing challenges but also unlocks a myriad of economic benefits. This chapter delves into the profound significance of integrating livestock with cropping systems and grasslands in modern agriculture, exploring how this synergistic combination enhances resource utilization, promotes resilience, and fosters a thriving agricultural sector.

The roots of integrated farming practices can be traced back to ancient agricultural traditions, where farmers instinctively recognized the advantages of combining crop cultivation and animal husbandry (Devendra and Thomas, 2002). Over time, this integrated approach evolved and adapted to different cultural and geographical contexts. In traditional mixed farming systems, livestock provided essential services such as draft power (Gomiero et al., 2011), manure for fertilization, and protein-rich food. As agriculture progressed with technological advancements, there was a shift toward specialized monoculture and intensive livestock farming (Herrero et al., 2013). However, the unintended consequences of these systems, including soil degradation, environmental pollution, and declining rural livelihoods, paved the way for a resurgence of interest in integrated farming methods (FAO, 2020).

Anderson defines organizations as structured human relationships wherein individuals purposefully associate in systematically arranged units to advance and achieve common purposes or interests not explicitly articulated within the institution. Each member assumes a formal status and role within this framework. Distinguishing an organization from an institution lies in its focused pursuit of narrowly defined objectives; it constitutes a collective of individuals organized to pursue specific aims. Conversely, an institution encompasses broader and more general objectives, constituting a set of socially endorsed procedures entailing patterned behavior, norms, and regulations. Organizations may function within institutions, thereby contributing to and facilitating the achievement of institutional objectives. The formation and structure of an organization evolve through the delineation of specialized activities, formulation of rules and regulations for operations, establishment of meeting schedules and locations, ultimately rendering the organization a clearly delineated entity with specific objectives, officers, and membership.

Introduction

As we all know that the 21st century has witnessed the changing phenomenon of information and its communication resulting a dynamic transformation not only in the social structure but also in the perception of human mind.  Exchange of information and knowledge has empowered the human being and enabled them to achieve sustainable development. From paper- based society to paperless society, information has remained the most valuable commodity.

Livestock is an integral component of Indian agriculture which is primarily a mixed crop-livestock farming system and plays an important role in the socio- economic life of India. Livestock contributes significantly to the growth and development of agricultural sector by providing a rich source of high quality products such as milk, meat and eggs and by supporting livelihood of more than two third of rural population. Livestock has a crucial and rapidly increasing role infood security and economic stability worldwide Livestock sector contributes for 4.11% of GDP and 25.6% of total Agriculture GDP. The importance of livestock has been undergoing a steady transformation with the contribution of livestock in total agriculture and allied sector Gross Value Added increasing from 24.32% in 2014-15 to 28.63% in 2018-19. Owing to factors such as population and economic growth, urbanization, improvements in transportation and storage practices,its future importanceformeeting human nutritional requirements of food and fiberand a major contributor to agricultural GDP is evident.

To alleviate the concerns raised by a rapidly growing demand of food security and the need of ensuring sustainability of natural resources, we need to better understandthe ways which wouldspeed up commercialization of livestock production so that it can contribute effectively to the bio-economy. Livestock performance and productivity can be improved by adopting proper diet and feeding practices, improved farm management and disease controlstrategies.

Introduction
Aquaculture is the farming of aquatic organisms, which includes fish, mollusks, crustaceans, and aquatic plants. Over the past forty years, aquaculture has played a significant role in increasing the global supply of fish for human consumption, leading to a marked rise in worldwide fish production. Nearly half (49.3%) of the world’s food fish are currently farmed for aquaculture (FAO, 2023). The proportion of inland fisheries and aquaculture in India’s overall fish production has increased from 46% in the 1980s to over 85% in recent years, resulting in the country with the second-largest aquaculture production. Fishing is a thriving industry with a wide range of resources and enormous potential in India. It is also a highly significant economic activity. Aquaculture may be the solution to ensuring global food security because fish can produce significantly more biomass per unit surface area than terrestrial animals. Aquaculture has a significant impact on world food security and is also considered a potential factor for the pollution of vast marine resources. The application of eco-friendly aquaculture methods can help the aquaculture industry thrive sustainably by reducing its negative effects on the environment. In the twenty-first century, biotechnology is becoming a crucial technology for long-term sustainability management and protection (Cantor, 2000).

Introduction
In the ever-evolving landscape of agriculture, the intersection of science and technology continually reshapes the way we approach crop improvement. Among the most revolutionary advancements in recent years is the advent of genome editing technologies. These powerful tools offer unprecedented precision and efficiency in modifying the genetic makeup of plants, holding immense promise for revolutionizing the field of plant breeding. Genome editing plays a crucial role in plant breeding by enabling plant breeders to make precise and targeted changes to the DNA of crops, offering significant advantages over conventional breeding methods. Besides, crop improvement, these new breeding tools shorten the time needed to introduce desirable traits into crops, from decades to just a few years. They have revolutionized plant breeding by providing breeders with the ability to efficiently create crops that are more resilient, better adapted, and can produce higher yields with fewer resources, ultimately contributing to sustainable food production and addressing the challenges posed by climate change and population growth.
This comprehensive review aims to explore the transformative potential of genome editing technologies in genetic improvement of crop plants. The review will commence by elucidating the underlying mechanisms of genome editing technologies, offering insights into the molecular machinery that drives precise DNA modifications mediated by ZFNs, TALENs, CRISPR/Cas, base editing, prime editing and other new variants of CRISPR/Cas systems, highlighting their respective strengths and limitations. From enhancing crop productivity and quality to conferring resistance against biotic and abiotic stresses, these technologies offer a versatile toolkit for addressing pressing agricultural challenges. Case studies and examples from recent research will illuminate the successes and potential pitfalls of employing genome editing in crop improvement efforts. Besides, the regulatory and ethical considerations surrounding the deployment of genome editing in agriculture will be addressed. In conclusion, this comprehensive review seeks to provide a holistic perspective on harnessing genome editing technologies in plant breeding. By elucidating the scientific principles, applications, regulatory challenges, and ethical considerations, we hope to facilitate informed discourse and decision-making surrounding the integration of these transformative tools into agricultural practices. As we stand at the precipice of a new era in crop improvement, embracing the potential of genome editing holds the promise of unlocking sustainable solutions to global food security challenges.

Introduction
Antimicrobial resistance (AMR) constitutes a profound global health crisis, jeopardizing the efficacy of antibiotics and posing a severe threat to the foundation of modern medical practice. The rise of multidrug-resistant (MDR) pathogens, which exhibit resistance to multiple classes of antibiotics, has significantly escalated the global burden of infectious diseases, complicating treatment protocols and increasing morbidity and mortality rates. According to the World Health Organization (WHO), AMR could lead to 10 million deaths annually by 2050 if current trends continue, accompanied by economic losses projected to reach trillions of dollars due to prolonged hospitalizations, increased healthcare costs, and reduced productivity. The traditional antibiotic development pipeline has stagnated, hampered by scientific complexities, high financial costs, and stringent regulatory frameworks, resulting in a critical shortage of novel antimicrobial agents. This necessitates the exploration of innovative strategies to combat AMR and preserve the utility of existing antibiotics. Among these strategies, Crispr-Cas (Clustered Regularly Interspaced Short Palindromic Repeats and Crispr-associated proteins) systems have emerged as a groundbreaking gene-editing platform with transformative potential for addressing AMR. Initially identified as a bacterial adaptive immune mechanism, Crispr-Cas has been repurposed to enable precise targeting of genetic elements, offering novel therapeutic, diagnostic, and environmental solutions. This chapter provides a comprehensive analysis of Crispr-Cas systems in the context of AMR, exploring their molecular mechanisms, diverse applications, current limitations, and future prospects across clinical, agricultural, and environmental domains. By leveraging the precision and programmability of Crispr-Cas, researchers aim to develop targeted interventions that mitigate the spread of resistance while minimizing collateral damage to beneficial microbial communities.

Introduction Data analytics is a systematic analysis of data or statistics. It is also the process of collecting, cleaning, transforming, interpreting, modelling and visualization the data. Such transformed data has to be further investigated to retrieve helpful information that may help conclude and support decision making. This study presents revising selected two relative valuation models (PE Model, PB Model) by replacing the most non-significant variables used in the model with the critical variable that is the potential cause for improving the model’s performance. The objective of relative valuation is to value assets based on how similar assets are priced in the market. This paper measures the valuation accuracy using Root Mean Squared Errors and refine the relative valuation models using the machine learning algorithm for predicting the value of a stock. The following steps helped to revise and refine the PE Model, PB model (Relative valuation models) to predict the value of Sensex stocks.

Abstract

Agroforestry is an ancient practice that farmers have adopted throughout the world. There are innumerable examples of traditional land use practices combining production of trees and agriculture crops on the same piece of land. In India, the organized agroforestry research began in 1979 when a Seminar on Agroforestry was organized at Imphal by the ICAR, New Delhi. As a follow up to this, ICAR launched an All India Co-ordinated Research Project on Agroforestry (AICRPAF) was started in 1983. The diagnostic survey and appraisal revealed that there are enumerable agroforestry practices prevalent in different agro- ecological zones of India occupying sizeable areas. However, spatial technologies like Geographical Information System (GIS), Remote Sensing (RS) and Geographical Positioning System (GPS) have yet to be implemented extensively in this field in India. The spatial technologies have shown great potential in natural resource management through out the world, especially in developed countries in the fields like forest cover mapping, agricultural planning, watershed management, land use planning, etc. In India the agroforestry land use occupy large areas but use of these technologies to estimate area has been initiated in year 2007 with DST sponsored project entitled ‘Spatial and Temporal analysis of agroforestry interventions in North-western India using GIS and Remote Sensing’ The area under agroforestry systems has been estimated/ mapped in two districts viz., Yamunanagar (Haryana) and Saharanpur (Uttar Pradesh), where intensive commercial agroforestry was predominant. Besides, the methodology developed as an out come of this study may be replicated for agroforestry systems existing in other parts of the country.

Underexploited

Unexploited fruit crops, jackfruit, tamarind, jamun, karonda, star fruit, etc having high nutritive value, are gaining popularly among the people. Similarly, many exotic fruits, Dragon fruit (Hylocereus spp), Avocado (Persea Americana Miller), Rambutan (Nephelium lappaceum L.), Mangosteen (Garcinia mangostana L), Passion fruit (Passiflora edulis Sims), Durian (Durio zibethinus L.,) Longan (Dimocarpus longan Lour) have been introduced in India. Exploitation of their genetic diversity could provide nutritional and livelihood security. There is a need to know about nutritional composition and health significance of these crops. Therefore, efforts have been made to know their potential nutritional and health benefits

Importance of Light in Microgreens Growth

Microgreens depend heavily on light for their growth and development. Microgreens, being photosynthetic organisms, are very dependent on light for the process of photosynthesis, which produces energy. Sufficient exposure to light is necessary for the production of chlorophyll, for vigorous leaf growth, and for the accumulation of beneficial chemicals such carotenoids and phenolics (Mocanu et al., 2021). Research by Demotes-Mainard et al. (2016) and Kopsell et al. (2005) highlights the direct relationship between microgreens' phytochemical composition and light quality, showing how changes in light spectrum affect it.

Introduction
Crop improvement is critical for tackling global food security challenges caused by population growth, resource scarcity, and climate change (Singha and Singha, 2024). Traditional breeding techniques, such as Sanger sequencing, have been around for a long, but their accuracy, speed, and usefulness are typically limited. Sanger sequencing is useful for small-scale inquiries, but its laborintensive procedures and limited throughput make it unsuitable for large-scale genome analysis. Molecular marker-based breeding strategies have proven to be effective tools for addressing these difficulties by increasing plant growth and overall quality (Bohar et al., 2020). In this respect, molecular markers like as single nucleotide polymorphisms (SNPs), insertions/deletions (indels), simple sequence repeats (SSRs), and structural variations (SVs) are expected to be useful for future breeding operations (Panahi et al., 2024). The discovery and characterization of these molecular markers is strongly reliant on advances in sequencing technology, namely next generation sequencing (NGS). Furthermore, NGS technologies have shown to be crucial for functional genomics, allowing for large-scale transcriptome and whole genome sequencing across plant taxa (Singh et al., 2024). These vast databases give a comprehensive picture of gene expression and genetic variation, making it easier to identify functional markers linked with certain features (Figure 1). The integration of NGS and bioinformatics technologies has simplified the study of these datasets, enabling more efficient discovery of markers and improving the use of marker-assisted selection (MAS) in breeding programs (Panahi et al., 2024).
The development of high-throughput genotyping technology has enabled substantial SNP-based research, which has improved our understanding of genetic diversity, population structure, and disease association (Yirgu et al., 2023). With the progress of genotyping by sequencing (GBS), SNPs have emerged as the most extensively utilized DNA markers in the twenty-first century (Thomson, 2014). SNP markers have significantly advanced plant breeding across a variety of crops, including tomato (Peterson et al., 2012), maize (Junta et al., 2020), rice (Razak et al., 2020), wheat (Wei et al., 2011), soybean (Kim et al., 2010), oil palm (Maryanto et al., 2020), cassava (Karim et al., 2020), and taro (Helmkampf et al., 2018). Overall, SNP markers have emerged as critical tools for genetic improvement and precision breeding across a wide range of crop species. SNPs initially trailed behind SSRs in DNA fingerprinting because they have fewer polymorphisms

Introduction
Angiosperms produce attractive and intricately structured flowers, within which their reproductive process occurs. In flowering plants, as in other plant groups, a diploid spore-producing generation (sporophyte) alternates with a haploid gamete-producing generation (gametophyte). The flower contains specialized structures, such as the stamen (or androecium) and the pistil (or gynoecium), where the respective male and female gametophytes are formed. The pollen grain serves as the male gametophyte, while the embryo sac serves as the female gametophyte. These gametophytes are responsible for producing sperm and egg cells, respectively facilitating their union during fertilization. The pollen grain contains the male gametophyte in angiosperms or gymnosperms. Conversely, spores function as a resting and dispersal phase for cryptogams (Moore et al., 1991). The study of pollen grains (produced by seed plants, angiosperms and gymnosperms) and spores (produced by pteridophytes, bryophytes, algae and fungi) is known as palynology. This discipline examines the structure and formation of pollen grains and spores, their dispersal and their preservation under various environmental conditions. Palynology serves as a valuable research tool for understanding many aspects of plant and animal metabolism. Moreover, a deeper understanding of pollen can aid plant breeders in enhancing efforts to improve global food and fiber supplies. In the anthers of higher plants, neither the developing pollen nor the surrounding tissues exhibit autonomous growth and development. Instead, the developing anther functions as a system where the gametophytic and sporophytic generations of the plant communicate, coordinate and co-participate in development. This chapter aims to understand the various aspects of gene activity that occur during pollen development.

Abstract
The rapid growth of aquaculture as a critical food production sector brings significant challenges, particularly the management of organic waste, which can harm aquatic ecosystems and reduce farm productivity. Polychaetes, a diverse group of marine annelid worms, present a sustainable and efficient solution to these issues. This chapter investigates their potential in aquaculture waste management, focusing on their ability to bio-assimilate organic matter, mitigate pollution, and enhance nutrient recycling. Polychaetes efficiently process uneaten feed, faecal matter, and organic sludge, converting these into protein and lipid-rich biomass suitable for use as high-quality feed ingredients or bio-products. Their integration supports the circular economy’s principle and integrated multi-trophic aquaculture (IMTA), fostering a synergistic system that minimizes waste and optimizes resource utilization. Additionally, polychaete application enhances water quality, reduces reliance on chemical treatments, and promotes sustainable aquaculture development. Integrating polychaetes into aquaculture systems, emphasizing their potential to drive eco-friendly practices, offers a pathway
toward more sustainable, resilient, and economically viable aquaculture production.

Introduction

Seaweeds, also known as marine macroalgae, grow in intertidal zones to deep sea environments. Based on their pigmentation, seaweeds are classified into three groups. They are red (Rhodophyta), green (Chlorophyta), and brown (Phaeophyta). Seaweeds are the primary producers in marine ecosystems; they also contribute to carbon fixation, nutrient cycling, reducing wave energy, preventing coastal erosion, and oxygen production. The complex, three dimensional growing nature of seaweeds helps habitat marine flora and fauna. Seaweeds are consumed as food in many countries, particularly in Asia due to their high nutritional content. Along with their nutritional value, they contain bioactive compounds with potential pharmaceutical and cosmetic applications. Agar and alginate from seaweeds are used in the food and pharmaceutical industries.

Seaweeds are integral part of marine ecosystems. Chemical pollutants including pesticides can disrupt these ecosystems by harming their populations, which directly or indirectly affect the marine environment. seaweeds are not only essential components of marine ecosystems. They are also consumed directly or indirectly in various food products (e.g., sushi, soups, and salads). The pesticides in the marine environment absorbed by seaweeds and bioaccumulate in the food chain. Seaweed cultivation is an emerging sector worldwide. The applications of seaweeds are food, pharmaceuticals, cosmetics and biofuels production. Seaweeds contaminate with pesticides leads to economic loss and reducing market demand. Manu of the seaweed consuming countries have safety limit for pesticide residues in food products, including seaweeds. The presence of pesticides in seaweeds also helps the development of risk assessment and management strategies including source identification, exposure pathways, and mitigating measures. The monitoring of pesticides in seaweeds provides the contamination levels over time, which helps to identifying the emerging issues, assess the effectiveness of regulatory measures, and guide adaptive management strategies.

Energy and food are the two main requirements for human civilization; however the demands for these two resources are increasing in a fast rate. Development of any region is reflected in its quantum of energy consumption. In this context, the situation in arid region is difficult. People burn firewood, agricultural waste and cow dung cake for cooking food causing damages to the fragile eco-system of arid zone. There is inadequate electrical power supply and hence villagers of remote arid areas are unable to derive general benefits. The kerosene is used for lighting and fast depleting diesel oil is used for running agricultural machinery including pumps. In this context solar energy is considered to be one of the promising sources in India.

About 12% of electricity production capacity in India is met through renewable energy sources. In India, national solar mission was launched in November 2009 with a target of 4000 MW grid and 1000 MW off-grid electricity generation from solar energy by the end of phase II (2013-2017), whereas these targets are 20,000 MW and 2000 MW, respectively by 2022. The target has been revised in 2015 to a total grid connected solar power generation of 1,00,000 MW comprising of 40,000 MW roof top generation and 60,000 MW grid connected solar power plants (Resolution of MNRE, Govt of India, No. 30/80/ 2014-15/NSM dated 1^st July 2015).

During his visit to India, President Barak Obama pointed out that our country is fortunate to have a youthful population with over half of the total population of 1.2 billion being under the age of 30. Out of the 600 million young persons, over 60 per cent live in villages. Most of them are educated. Gandhiji considered the migration of educated youth from villages to towns and cities as the most serious form of brain drain adversely affecting rural India’s development. He therefore stressed that we should take steps to end the divorce between intellect and labour in rural professions.

The National Commission on Farmers (NCF)(2004-06) emphasised the need for attracting and retaining educated youth in farming. The National Policy for Farmers, placed in Parliament in November 2007, includes the following goal of the new policy:

To introduce measures which can help to attract and retain youth in farming and processing of farm products for higher value addition, by making farming intellectually stimulating and economically rewarding.

Introduction

The rumen ecosystem is essentially a fermentation system that houses a vast array of different microbes. Ruminants typically browse low energy forages, such as grasses or other plant material, rich in fibre but not easily accessible to the ruminant without rumen fermentation. These forages are literally food for the microbes present in the rumen first and then, in turn, the products of these microbes are the feed for the ruminant. Microbes break down forage in the anaerobic rumen environment and the products of microbial fermentation provide the ruminant with metabolisable compounds, such as short chain fatty acids, while the microbes themselves account for around 90% of the amino acids entering the lower intestine. There are many significant challenges to investigate rumen ecology.

Introduction

The Indian arid zone, which occupies 38.7 million hectares in the states of Rajasthan, Gujarat, Punjab, Karnataka, and Andhra Pradesh, is characterized by low and erratic rainfall with a coefficient of variation fluctuating from 40 to 70% and extremes of temperature (1–48º C), poor-quality underground water, high wind velocity, and sandy soils. These vast land resources are blessed with rich agro-biodiversity despite all these aberrations that support the high human and livestock populations and have beneficial climatic conditions for producing quality fruits and vegetables. Recently, the immense potential of arid horticulture has been realized, and the area under cultivation of arid crops is increasing enormously. The production also increases with the increased cultivated area, which opens up the probability of establishing a market glut with underutilized foods.

Arid Fruits and Vegetables

Arid and semi-arid regions of the country are blessed with a variety of horticultural crops such as date palm, bael, aonla, pomegranate, fig, mulberry, Jamun, ker, karonda, lasora, wood apple, ber, bordi, khejri, kachri, snap melon, drumstick, cluster bean, and methi. Most of these crops are highly perishable and cannot be stored for extended periods due to uncongenial atmospheric conditions such as high temperatures and low relative humidity.

13.1 Introduction

Winds are the motion of air around the earth. This movement in air is caused by the uneven heating of the planet’s surface by the sun. The idea of using wind as a form of power is not new. The traditional applications of wind were primarily as sources of kinetic energy for rural, agricultural and a limited number of industrial uses such as pumping water and grinding grain.

Presently wind energy can be used for two major applications, such as wind mills for pumping water for drinking as well as for irrigation purposes and second application is as aero-generator for electricity generation for domestic and industrial uses. In addition to this, presently wind energy battery charger are also available, which can store energy for lights, radio communication, hospital equipment and to power various emergency related equipment.

The wind energy has an enormous resource, but the problems of utilizing the winds are many and varied. Wind energy is very diffuse in nature and local topographical features significantly alter the prevailing winds thus leading to the extremely site specific nature of wind energy.

Scientirsts have estimated that as much as 10 per cent of >the world’s electricity could be provided by wind generators by the middle of 21 century. India has estimated wind power potential of 45,000 MW. India now, ranks fourth in the world in wind power generation.

The world’s largest wind farms are in California, where wind turbines can generate power upto about 1120 MW. The first wind mill used as source of electric power was built in Denmark in 1890. Presently in India about 2382 MW of electricity is being produced through wind energy.

Introduction

Microbial inoculants are “microorganisms that are added to soils or plant surfaces to promote plant growth and health”. These microorganisms include bacteria, fungi, and other microorganisms that have beneficial effects on plants. They have been used in agriculture for many years to improve plant growth and health. They can be used in various ways, including in seed treatments, soil inoculation, and foliar sprays. They work by colonising the root zone or plant surface and providing a range of benefits to the plant. These benefits include nutrient acquisition, disease suppression, and stress tolerance (Callaghan., 2022). Ultimately, their application in agriculture is to increase crop yields, improve soil health, reduce the use of chemical fertilisers and pesticides, and generate sustainable income for farmers. The microbial inoculant market size is expected to generate revenue of USD 24.6 billion by 2027 and is estimated to be valued at USD 12.9 billion in 2022, at a compound annual growth rate (CAGR) of 13.7% from 2022 to 2027. (Markets and Markets: Global Forecast Report 2022–2027). The biofertilizers market in India is estimated to increase from $110.07 million in 2022 to $243.61 million by 2029, at a CAGR of 12.02% during the forecast period (Biofertilizers market Size: Global analysis, 2029). This chapter discusses the use of microbial inoculants in agriculture and their potential as an income-generating tool for farmers.

1. Introduction

Web 2.0 speaks about the second version of web advancement and draft that aims to make it easier to communicate and safer to share information, as well as to make the web more interoperable and user-centered. Social networking sites, video-sharing sites, Wikis, blogs, and folksonomies are just a few of the web-based communities, hosted services, and apps that have grown and changed because of Web 2.0 ideas. (King and Brown, 2009; Wikipedia, 2010c). According to Birdsall (2007) web 2.0 is a social revolution since these tools have brought new changes in the society. According to O'Reilly (2005) the advent of Web 2.0 has revolutionized the way individuals and organizations interact with the internet, marking a significant shift from a static web experience to a dynamic, user-driven environment. This transformation is characterized by the emergence of platforms and tools that empower users not only to consume content but also to create, share, and collaborate on it. As a result, Web 2.0 has fostered a more participatory online culture, where users actively engage in the generation and dissemination of information.

Introduction
Plant being sessile are subjected to a myriad of biotic and abiotic stresses that impede growth and resulting significant losses in crop productivity globally (Bhat et al., 2019; Ganie & Reddy, 2021). In this context, there is an immediate need to develop high yielding climate-resilient crop varieties for ensuring food security in the face of increasing population growth. Although conventional breeding has achieved notable success in the development of high-yielding crop varieties (Bhat et al., 2020), but this approach is slow to maintain pace with ever increasing population. In this regard, more recent approach of genomics-assisted breeding (GAB) has emerged as a pivotal approach to develop the high-yielding climate resilient crop varieties (Bhat et al. 2021). Although, low-throughput sequencebased markers like simple sequence repeats (SSRs) have been extensively utilized in molecular breeding programs, but they have the limitations of reduced genomic coverage and high cost (Varshney et al., 2014; Zargar et al., 2015). In this context, the emergence of second-generation DNA marker systems has provided higher genomic coverage and low cost in marker-assisted breeding. For example, recent advancements in next-generation sequencing (NGS) and genotyping platforms have substantially enhanced marker density and genomic coverage while reducing costs (Przewieslik-Allen et al., 2019); thus rendering them commercially available for both model and non-model crop species (Huang & Han, 2014; Rasheed et al., 2017). These high-throughput genotyping platforms provides millions of DNA polymorphisms (Bassi et al., 2016; Ganal et al., 2012), thereby enhancing gene mapping resolution and prediction accuracy in genomic selection (GS) (Robertsen et al., 2019; Yu et al., 2019). Most of the agriculturally important crop traits, such as yield, quality, and stress tolerance, possess complex inheritance i.e., governed by multiple genes with minor effect on trait of interest as well as are highly influenced by genotype-by-environment (G × E) interactions (Voss-Fels & Snowdon, 2016). The conventional linkage mapping approach has elucidated the genetic basis of agriculturally important complex traits but this approach involves the use of bi-parental mapping populations which are constrained by the limited genetic diversity, low resolution, and restricted recombination events (Brachi et al., 2011; Collard et al., 2005). Consequently, the genome-wide association study (GWAS) has emerged as a powerful approach for dissecting the genetic basis of complex quantitative traits in crop plants, resulting higher resolution and allelic diversity (Varshney et al., 2020; Zhu et al., 2008). Moreover, owing to the availability of cost-effective and high-density genotyping platforms, has allowed the routine use of GS in the crop breeding which is more recent approach of GAB (Crossa et al., 2017). In recent years, the advent of next-generation sequencing (NGS)-based genotyping techniques has significantly allowed the genotyping of extensive germplasm collections, enabling comprehensive GWAS and GS analyses (Annicchiarico et al., 2017; Zargar et al., 2015). Nonetheless, the predominant limitations impeding the utilization of SNPs in the GWAS and GS approaches encompass their inherently biallelic nature, the occurrence of rare alleles, and the prevalence of linkage drag (Voss-Fels & Snowdon, 2016; Wray et al., 2013).

Abstract

More than one-third of food is lost or wasted in post-harvest operations in India. Decreasing the post-harvest losses (PHL) may be a sustainable solution to increasing food availability and improving farmers’livelihoods. As per Associated Chambers of Commerce of India, India loses approximately US$ 14.33 billion annually on account of PHL (ASSOCHAM, 2017). The objective of this study is to analyse the agricultural wastes that are produced in the value chain for a modern trade retailer, identify their causes, and discuss methods for minimising field wastages. A case study approach has been used to depict the agricultural value chain (vegetable segment). A field visit was conducted to a farmland and a privately operated Collection Center in Barasat area of West Bengal. The author discusses solutions towards minimising harvest wastages in the farm by focusing on waste reduction. Post-harvest wastages beyond the farm can be reduced by undertaking measures that focus on waste management. Going forward, adoption of technologies by farmers may lessen inefficiencies such as wastages and improve their income. Further scope for research lies in exploring joint interventions by private players, government agencies, non-profit organisations and entrepreneurs through public-private partnership models or through development of clusters for creating sustainable value chains and achieving greater profitability.

As we stand at the threshold of this final chapter, “Harvest For Future,” we reflect on the journey that has brought us to this moment. Throughout the preceding chapters, we’ve explored the intricate relationships between rural households, agricultural practices, and the ever-changing climate. We’ve examined the critical role that operational agricultural meteorology plays in empowering rural communities to adapt, innovate, and thrive in the face of uncertainty. From understanding local weather patterns to leveraging climate-resilient agricultural practices, we’ve traversed the complexities of sustainable rural development. Our exploration has taken us through the nuances of climate variability and its impact on agricultural productivity, water management, and soil health. We’ve discussed the importance of effective early warning systems, drought management strategies, and crop insurance programs in mitigating the risks associated with climate-related shocks. We’ve also highlighted the critical role that information and communication technologies can play in disseminating climate information, agricultural advisories, and market intelligence to rural households. Moreover, we’ve examined the human side of sustainable rural development, including the social, economic, and cultural factors that influence decision-making processes within rural households. We’ve looked at the ways in which agricultural meteorology can be used to support climate-resilient agriculture, enhance food security, and promote sustainable livelihoods. Through case studies and examples, we’ve seen how operational agricultural meteorology has been successfully implemented in various parts of the world, leading to improved agricultural productivity, increased incomes, and enhanced resilience among rural households. Now, as we look to the horizon, it’s time to distill the insights, strategies, and lessons learned into a cohesive vision for the future. What does a sustainable rural household look like in the context of a rapidly evolving climate? How can operational agricultural meteorology continue to support and uplift these communities, fostering resilience, equity, and prosperity? In this final chapter, we’ll synthesize the key takeaways from our exploration and chart a course for harnessing the full potential of agricultural meteorology to create a more sustainable, food-secure, and climate-resilient future for rural households worldwide. We’ll explore the opportunities and challenges associated with emerging technologies, such as artificial intelligence, big data analytics, and the Internet of Things, and how they can be leveraged to enhance the delivery of climate services to rural households. We’ll also examine the policy and institutional frameworks that are needed to support the widespread adoption of operational agricultural

1. INTRODUCTION

Every fruit or vegetable is harvested keeping in view, its intended use. At what stage it should be harvested, is indicated by the maturity index. The chapter focuses on these and postharvest quality of fruits and vegetables.

2. FRUIT MATURITY

"Maturity of a fruit can be defined as that stage at which a commodity has reached a sufficient stage of development that after harvesting and postharvest handling, its quality will be at least the minimum acceptable to the ultimate consumer”. Maturity is of two types:

21.1. What?

Harvest is the process of gathering the end produce from mature crops in the fields. Harvest marks the end of the growing season, or the growing cycle for a particular crop. Harvesting is the most labour-intensive activity. Moreover, timely harvest before shattering of the produce or before rain assumes significance. As adjacent fields sown at the same time come to harvest simultaneously, farmers face great problem in getting manual labour for harvesting and cleaning their produce. To overcome these difficulties, different types of harvesters have been developed from time and again to suit different crops, situation and conditions.

21.2. Harvester and reaper

Harvesters are used to cut the crop after they mature. In such cases, threshing is to be done separately. Harvesters are available for a wide range of crops belonging to cereals, pulses, millets, oilseeds, fruits and plantation crops. Reapers are used to harvest crops such as rice, wheat, soybean, mustard, rapeseed, safflower and other thin stemmed crops. Reapers are operated using power tiller.

Introduction

Harvesting and handling are the equally important activities as the entire production system as an individual activity. Therefore, proper harvesting and handling is essential to assure the farm income. There are various factors which directly affect the storage life of fruits and vegetables as below. The natural limits to the post -harvest life of all types of fresh produce are severely affected by other biological and environmental conditions.

Temperature: An increase in temperature causes an increase in the rate of natural respiration of all produce and food reserves and water content become depleted. The cooling of produce will extend shelf-life by slowing the rate of respiration.

Transpiration and water losses: High temperature, low humidity in the store and injuries to produce can greatly increase the loss of water from stored produce beyond that unavoidable lost from natural causes. Maximum storage life can be achieved by storing only undamaged produce at the lowest temperature tolerable by the crop and at the relative humidity appropriate for the produce.

Mechanical damage: Damage caused during harvesting and subsequent handling (i.e. injuries, impact bruising) increase the rate of deterioration of produce and renders it liable to attacks by decay organisms even under refrigerated storage. Mechanical damage to root crops will cause heavy losses owing to bacterial decay and must be remedied by curing the roots or tubers before storage. Curing is a wound –healing process.

Decay in storage: Decay of fresh produce during storage is mostly caused by the infection of mechanical injuries provoked by micro organisms, mostly bacteria and fungi. Furthermore, many fruits and vegetables are attacked by decay organisms which penetrate through natural openings or even through the intact skin. These infections may be established during the growth of the plant in the field but lie dormant until after harvest, often becoming visible only during storage or ripening.

After doing all hard work during fruit production the last operation is harvesting on field. Though it is last operation, it should be done very carefully to get the quality harvest. Harvesting of fruits mainly depends upon the nature of fruit. Here nature refers to the classes of fruits divided on the basis of their respiratory pattern and ethylene production. On the basis of the respiratory pattern the fruits can be divided in to two categories, first one is climacteric and the second one is non climacteric.

1. Climacteric fruits: The meaning of word „climacteric is a critical period or event. Here, climacteric refers to the event of respiratory rise before the ripening phase. Those fruits which show such patterns are known as climacteric fruits (Taiz and Zeiger, 2002) Examples: Mango, guava, apple, banana, sapota, papaya, peach, pear, plum, fig, Annona.
2. Non climacteric fruits: Non climacteric fruits do not exhibit the respiration and ethylene production rise (Taiz and Zeiger, 2002). Examples: Citrus, grapes, pineapple, pomegranate, litchi, ber, jamun, cashew, cherry, strawberry.

4.1 Harvesting

Pomegranate being non-climacteric fruits should be picked when fully ripe. Its fruits become ready for picking 120-130 days after fruit set. Mature fruits should be immediately removed from the plants as delay in harvesting leads to fruit cracking. Fruits harvested at a premature stage have poor keeping quality and are prone to damage during handling and transport. The fruits are harvested when outer rind becomes yellowish and the fruit when tapped produces a metallic sound. The round fruits become flattened from all the sides and basal beak shaped portion shrinks at the time of maturity. Fruits are harvested with the help of secateurs by retaining 1 cm stalk with the fruit. All the fruits should be harvested in 2-3 pickings within a span of one month.

Standard Operating Protocol for Export of Banana
Banana is one of the important fruit grown in India, as far as its export is concerned it is very limited which is below 1%. For export market it should be harvested at 85% maturity or the bunch is ready to harvest in 80-82 days after shooting initiation. Bunches are to be harvested carefully with two people. One person cut the hand and another person put the bunch onto the padding shoulder. Bunches should be slant cut with sickle shaped sharp knife free from any contamination. For export purpose banana fingers should be square, lie close together, hard, clean and free from any infestation and mucilaginous thread of pulp should be 4-5 cm in length. Skin should not be separated from pulp and no brown spot under the skin. De-handing must be done with sharp chisel type de-handing tool, by leaving maximum crown attached to the hand. The crown should be cut evenly; otherwise its outer finger may be detached. Other way to De-handing by using the nylon thread. It is easy method and it allows maximum crown attach with the land with minimum latex flow. The hands should be carefully paced in clean water which has alum 1 gm litre-1 or sodium hypochlorite (200 ppm) as surfactant for removing the latex and killing the micro-organism after that fruit must be packed in 20-25 kg capacity crates having foam in bottom and in between hands also. The most effective control of post harvest diseases and control of ripening of banana is treating the hands with 1.0% CISH METWASH an organic formulation for 30-60 seconds after that it should be carefully removed from this organic formulation and keep it in front of high speed fan for drying.

Harvesting: “Removal of entire plant or economic parts after maturity from the field" is called harvesting. It includes the operation of cutting, picking, plucking or digging or a combination of these for removing the useful part or economic part from the plants / crops. The portion of the stem that is left in the field after harvest is called as stubble. The economic product may be grain, seed, leaf, root or entire plant.

Harvest Index: (H.I): It is the ratio of the economic yield to the total biological yield expressed as percentage.

H.I = Economic yield / Biological yield x 100

Time of Harvesting: If the crop is harvested early, the produce contains high moisture and more immature ill filled and shriveled grains. High moisture leads to pest attack and reduction in germination percentage and impairs the grain quality.

Late harvesting results in shattering of grains, germination even before harvesting during rainy season and breakage during processing.

Post-Harvest Losses

A post-harvest loss is defined as the measurable qualitative and quantitative food (including fruits and vegetables) loss along the supply chain, starting at the time of harvest till its consumption or other end uses (Hodges et al., 2011). Pineapple fruits are highly perishable in nature and continuously respired even after harvesting which limited its shelf-life leading to the storage problems (Hossain and Bepary, 2015) and decline in production due to post-harvest losses (Babalola et al., 2008). During the storage for distant marketing, pineapple fruits easily losses its moisture content through transpiration and become more susceptibility to microbial spoilage (Hossain and Bepary, 2015). In India the top five leading pineapple producing states are West Bengal, Assam, Karnataka, Meghalaya and Manipur (Anonymous, 2018). The measurable qualitative and quantitative losses of pineapple at post-harvest level are from the various stages of handling from the farm level up to the consumers (Table 1 and 2).

Historically, humans have utilized animal skins for various purposes including shelter, clothing, weapons, and food containers. In contemporary times, skins and hides significantly contribute to foreign exchange earnings within the animal husbandry sector and are widely employed by the leather industry. At slaughterhouses, hides and skins are generally collected and dispatched to tanneries on the same day. If a tannery is not in close proximity, hides are preserved through salting or curing prior to being transported in batches.
A skin (the outer covering) from a fully grown large animal is termed a hide; it is comparatively large, thick, and heavy, typically exceeding 30 lb (13.62 kg) for cattle or buffalo. Conversely, the outer covering of smaller animals such as sheep, goats, pigs, and young calves is known as skin. This type is smaller, thinner, and lighter. The term “slunk” refers to the skin of an unborn calf, which is often utilized for parchment, light suede, or drum skins. Calf skin is derived from young calves that have not yet reached maturity, and it is generally softer and more delicate than the hides of older animals. Its fine texture renders it highly sought after for premium leather goods. In contrast, kip skin is obtained from older but still immature calves. It is thicker and more robust than calf skin while being more refined than adult hides. Kip skin is recognized for its blend of durability and softness, making it ideal for longlasting leather products.
Hides and skins constitute approximately 4-11% of an animal’s live weight, influenced by factors such as species, age, breed, and health. In cattle, the average hide yield is about 7% of live weight, whereas in sheep and goats, the average skin yield is around 11% of live weight. Hides and skins rank among the most valuable by-products of animals and are transformed into leather through the tanning process. The trimmings are repurposed for the production of glue, artifacts, or as feed supplements.

Harvesting and processing natural honey are integral parts of beekeeping that demand attention to timing, technique, and ethical practices to protect both the integrity of the honey and the well-being of the bees. In natural farming systems, the emphasis lies not only on honey yield but also on maintaining balance with the surrounding environment and the bees themselves. Natural honey is prized for its pure quality, medicinal benefits, and nutritional richness, which can only be safeguarded through traditional, low-intervention approaches. The central objective is to harvest only the surplus honey, ensuring colonies retain sufficient reserves to sustain themselves through adverse seasons.

Honey is usually harvested after the flowering season, once nectar flow has been abundant and bees have stored ample honey for their use. A key tenet of natural beekeeping is to avoid stripping the hive entirely of its reserves, thereby safeguarding the colony’s survival. Mature honey is collected from capped combs, which signal that the honey has reached the correct moisture content. In contrast to commercial methods that may rely on chemicals or excessive smoke to drive bees away, natural beekeeping encourages gentle handling using a bee brush or a small amount of smoke to move bees without causing them distress.

In contrast to commercial methods that may rely on chemicals or excessive smoke to drive bees away, natural beekeeping encourages gentle handling using a bee brush or a small amount of smoke to move bees without causing them distress. After collection, honeycomb can be processed differently depending on the hive design. In top-bar or traditional hives, the comb can be consumed directly or gently crushed and strained using muslin cloth to extract the honey from wax and debris. Heat should not be applied during extraction, as it can destroy vital enzymes and antioxidants present in raw honey. Filtration should be minimal to retain beneficial elements such as pollen, propolis, and the honey’s natural flavor. Clean, food-grade storage containers—preferably stainless steel or glass—are ideal for preserving quality and preventing contamination. Processing also demands high standards of hygiene, accurate labeling, and careful moisture control. To prevent fermentation, honey’s moisture content should stay below 18%. Since honey is hygroscopic, it should be stored in airtight
