The Vegan

by Andrew Lipstein

Herschel Caine is a master of the universe. His hedge fund, built on the miracle of machine learning, is inches away from systematically sapping profits from the market. His SoHo offices (shoes optional, therapy required) are ready for desperate investors to flood through the doors. But on May 12, his mind is elsewhere-at his Cobble Hill townhouse and the dinner party designed to impress his flawless neighbours. When the soiree falters, Herschel concocts a prank that goes horrifically awry, plunging him into a tailspin of guilt and regret. As Herschel's perfect world starts to slip away, he clings to the moral clarity he finds in the last place he'd expect: a sudden connection with his neighbour's dog.A wildly inventive, reality-bending trip, The Vegan holds a mirror up to its reader and poses a question only a hedge fund manager could: is purity a convertible asset? The more Herschel disavows his original sin, and the more it threatens to be revealed, the more it becomes something else entirely: a way into a forgotten world of animals, nature, and life beyond words. Andrew Lipstein, the author of Last Resort, a novel that 'you'll think about . . . for weeks after you read the last pages' (Los Angeles Times), challenges our ideas of contemporary morality in his scintillating, provocative second novel.

Vegan Alternatives for Leather (Sustainable Textiles: Production, Processing, Manufacturing & Chemistry)

by Subramanian Senthilkannan Muthu Mukta Ramchandani

Environmental toxicity and sustainability are major areas of research for the leather industry, as well as for the larger luxury and fashion industry. Several alternatives to traditional animal-based leather have been introduced in the market as “vegan” leather, e.g. the pineapple skin leather Piñatex, mycelium (mushroom leather), apple leather, cactus leather, and PU/PVC faux leather. However, a clear assessment of the sustainability (e.g. carbon/water footprint, LCA) for these alternatives is missing. The aim of this book is to provide clarity and a coherent structural assessment of sustainable vegan or vegetarian alternatives of leather. This book contributes to the current research within sustainability and environmental impact, production, and consumption aspects of these materials.

Vegetable Crops (Handbooks of Crop Diversity: Conservation and Use of Plant Genetic Resources)

by Pritam Kalia

The volume on Vegetable Crops as a part of series entitled “Handbooks of Crop Diversity: Conservation and Use of Genetic Resources” will be a unique resource, first of its kind, which will elaborate on origin, evolution, taxonomy, identification, chemical characterization, and genetic improvement of Vegetable Crop Plants. Vegetable crops are an important group of crops comprising solanaceous vegetables, Cole crops, Cucurbitaceous crops, Bulb crops, Root crops, Tuber crops, legume vegetables, leafy & salad vegetables, Okra etc. There is tremendous diversity within each group of vegetable crops. This genetic diversity is from the point of view of landraces and varieties of vegetable crops species used for food, processing, nutraceuticals, pharmaceuticals, etc. Vegetables being an integral part of human diet being rich source of diverse nutrients such as vitamins, minerals and antioxidants, they play an important role in balancing the diet and tackling malnutrition. Besides, due to their intensive cultivation, they also play an important role in enhancing per unit area production and productivity, cropping intensity enhancing, thereby, the farmers income, especially that of small and marginal farmers, and providing job opportunities. The genetic improvement of vegetable crops facilitate continued breeding of varieties with greater resilience to stresses and productivity is mainly dependent on overall genetic variation found in individuals belonging to the cultivated species and/or ancestral species related to cultivated species of vegetable crops. Since genes of interest can be tapped from plant sources for their introduction through controlled breeding processes for genetic improvement, and incorporating of desirable external and internal quality traits, therefore accessibility to the information about these plant genetic resources is key to the success of the breeding efforts. Since there is a need of comprehensive information about the genetic resources, therefore it is important to facilitate their conservation and long-term sustainable use in research and improvement. The comprehensive information on the availability of genetic diversity in each vegetable crop species in this volume would facilitate priority conservation in gene banks, research and use in vegetable crop improvement. Realizing the importance of genetic variability in the improvement of vegetable crops from the point of view of biotic and abiotic stress resistance, enhanced micronutrient, climate change, enhanced shelf life, nutraceuticals, bioactive compounds, especially national and international efforts further need to be stepped up for collection, characterization, evaluation, and conservation of vegetable crops genetic resources to facilitate search for new genes, research and their use in vegetable crops improvement. During 21st century, genomics and marker assisted tools have gained importance for hastening the crop improvement programmes by enhancing breeding efficiency. Realizing that population in South Asia and Southeast Asia is facing acute problem of under and malnutrition, the emphasis on dietary diversification with vegetables is therefore being stressed. Besides, to enhance farmers income much emphasis is being laid on development of varieties having diverse maturity, growth habit, resistance to diseases and insect pest to reduce the use pesticides, enhanced nutrients and shelf life. For these traits, we have to look into landraces, and wild relatives for the traits of interest. Therefore, it has been felt to bring out a vegetable volume with additional accessory and supplemental information, analyses and specifically filtered information which can go a long way in promoting research, search for new genes/alleles, revealing the opportunities available for exploitation of PGR in generation of cultivars to meet upcoming challenges of vegetable crop improvement and diversification and requirement of cultivars for processing, nutraceutical and pharma

by Joan Sabaté

Approximately 12 million U.S. citizens consider themselves vegetarians, and 13.5 percent of all U.S. households claim to have at least one family member practicing some form of vegetarianism. In the past 30 years, scientific endeavors in the area of vegetarian nutrition have progressively shifted from investigating dietary concerns held by nutritio

Vegetarian Nutrition and Wellness

by Winston J. Craig

A large amount of research effort goes into assessing the health benefits of a plant-based diet, resulting from human desire to consume a more sustainable diet that is less destructive of the earth’s natural resources. In addition, a growing number of people are choosing the vegan or total vegetarian diet because of the potential to greatly reduce the risk of chronic diseases and mortality rates. Although this interest in plant-based eating is popular, there exist concerns on the safety of some vegetarian diets, especially a vegan diet. This book describes issues of the vegetarian diet and outlines ways to prevent nutrient deficiencies. Vegetarian Nutrition and Wellness focuses on synthesizing research around vegetarian diets and human health. A major section of the book deals with how a vegetarian diet protects population groups from the major chronic diseases, such as cardiovascular diseases, obesity, and various cancers. Based upon ecological and clinical studies, chapter authors explain the health-promoting properties of plant-based diets, and compare/contrast health outcomes obtained from consuming omnivorous diets with a vegetarian or vegan diet. Fruits and vegetables figure prominently in vegetarian diets and provide a substantial effect in disease reduction and health-promoting properties of a plant-based diet. Vegetarian Nutrition and Wellness is written for the academic community, registered dietitians, health professionals, and graduate students in nutrition and public health. Each chapter provides a comprehensive review of the scientific literature and includes a concise summary at the beginning of each chapter. The time is ripe for this book to update the scientific community with a collage of well-documented topics on vegetarian nutrition.

Vegetation and Climate

by Siegmar-W. Breckle M. Daud Rafiqpoor

Vegetation, soil and climate are the most important components of ecological systems. The book represents a compact synthesis of our current knowledge about the ecology of the Earth and is thus the basis for understanding the major interrelationships in a global perspective. In the first part, with a rich endowment of illustrations and photographic material, the well-introduced book deals with the essential processes and operations on the Earth's surface that lead to the formation of the vegetation cover with its distinctive zonation. In the second part, the individual vegetation zones as large-scale ecosystems (i.e. zonobiomes of the biosphere) are consistently described comparatively according to certain criteria. In a short and compact form, the main characteristics and structures as well as examples of ecosystem processes are discussed. The large-scale ecosystems are at the same time the basis and reference system for all anthropogenic changes that have drastically altered the vegetation in the last millennia, but especially in the 20th century.This book is a translation of the original German 1st edition Vegetation und Klima by Siegmar-W. Breckle and M. Daud Rafiqpoor, published by Springer-Verlag GmbH Germany, part of Springer Nature in 2019. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation. Springer Nature works continuously to further the development of tools for the production of books and on the related technologies to support the authors.

Vegetation and Soils: A World Picture

by S. R. Eyre

Vegetation and Soils is an introduction to the study of vegetation and soil distribution. In this accessible work, S. R. Eyre describes the distributions of these two important elements in the landscape. The book progresses regionally, and the land areas of the earth are subdivided according to the distribution of their main vegetation and soil types. The author argues that the nature of the soil is not determined by vegetation any more than it is determined by climate, but the nature of the vegetation always has some bearing on the nature of the soil, and vice versa.Eyre studies the ways in which plant communities and soil profiles develop and the complexity of the vegetation-climatic relationship. The middle and high latitudes are examined, as well as the tropical regions. In order to avoid broad generalizations of vast regions, the example of the British Isles is used to show that vegetation and soil maps can be misleading on a continental scale. The book concludes with a series of vegetation maps, which show the distribution of plant formations. Also included are tables providing climatic correlations with vegetation and a glossary of relevant terms.This classic work shows the intimate connection between vegetation development and soil development. For this reason, this book is a major contribution to the study of the physical aspects of geography and will be of particular interest to students of geography, botany, and agriculture.

Vegetation Dynamics

by Eamus, Derek and Huete, Alfredo and Yu, Qiang Derek Eamus Alfredo Huete Qiang Yu

Understanding ecosystem structure and function requires familiarity with the techniques, knowledge and concepts of the three disciplines of plant physiology, remote sensing and modelling. This is the first textbook to provide the fundamentals of these three domains in a single volume. It then applies cross-disciplinary insights to multiple case studies in vegetation and landscape science. A key feature of these case studies is an examination of relationships among climate, vegetation structure and vegetation function, to address fundamental research questions. This book is for advanced students and researchers who need to understand and apply knowledge from the disciplines of plant physiology, remote sensing and modelling. It allows readers to integrate and synthesise knowledge to produce a holistic understanding of the structure, function and behaviour of forests, woodlands and grasslands.

Vegetation of Central Asia and Environs

by Dilfuza Egamberdieva Münir Öztürk

Central Asia is a large and understudied region of varied geography, ranging from the high passes and mountains of Tian Shan, to the vast deserts of Kyzyl Kum, Taklamakan to the grassy treeles steppes.This region is faced with adverse conditions, as much of the land is too dry or rugged for farming. Additionally, the rich specific and intraspecific diversity of fruit trees and medicinal plants is threatened by overgrazing, oil and mineral extraction, and poaching. Countless species from the approximately 20 ecosystems and 6000 plant taxa are now rare and endangered.Traditional vegetation studies in this region are far from adequate to handle complex issues such as soil mass movement, soil sodicity and salinity, biodiversity conservation, and grazing management. However, data analysis using a Geographical Information System (GIS) tool provides new insights into the vegetation of this region and opens up new opportunities for long-term sustainable management. While vegetation planning can occur at a property scale, it is often necessary for certain factors, such as salinity, to be dealt with on a regional scale to ensure their effective management. GIS increases the effectiveness and accuracy of vegetation planning in a region. Such regional planning will also greatly increases biodiversity values.This book systematically explores these issues and discuses new applications and approaches for overcoming these issues, including the application of GIS techniques for sustainable management and planning. Professional researchers as well as students and teachers of agriculture and ecology will find this volume to be an integral resource for studying the vegetation of Central Asia.
