        Vegetable Seeds

        Production and Technology

        by Gregory E Welbaum

        Most food and fiber crops are produced from seed. This means that the world's population is dependent on annual seed production for its food supply. Vegetable seed production is much different and more challenging than production of grain crops. This book explains the biology and technology behind producing, maintaining, and enhancing the quality of vegetable seeds from breeding through to the marketed product. It begins with six chapters on a broad range of seed-related topics: the importance of seeds, reproductive biology of plants, genetic improvement strategies, quality assurance of seed production, post-harvest seed enhancement, and organic production. The remaining chapters cover seed production in eleven important vegetable families. Each chapter provides a description of the botany, types and cultivars, genetic improvement, pollination, soil fertility management, pest management, crop production, harvesting, post-harvest handling, and seed yields. The aim of this book is to educate how to produce high-quality vegetable seeds. Incorporating both current methodologies and recent research results, it is suitable for students, researchers, and professionals in the seed industry.

        Organic Farming

        An International History

        by Jessica Aschemann, Thomas Cierpka, Gunter Vogt, Michael Sligh, Deborah H Stinner, Urs Niggli, Susanne Padel, Otto Schmid, Bernard Geier, Philip Conford, Inger Källander, Dina Foguelman, Els Wynen, Katherine DiMatteo. Edited by William Lockeretz.

        Beginning as a small protest to the industrialization of agriculture in the 1920s, organic farming has become a significant force in agricultural policy, marketing, and research. No longer dismissed as unscientific and counterproductive, organic techniques are now taken seriously by farmers, consumers, scientists, food processors, marketers, and regulatory agencies in much of the world. Organic farming is both dynamic and forward-looking but is also rooted in tradition. It is these traditions that can provide valuable starting points in debates over how organic farming should meet new challenges such as globalization, the emergence of new production techniques, and growing concern over equity and social justice in agriculture. Complementing general discussions with case histories of important organic institutions in various countries, this comprehensive discussion is the first to explore the development of organic agriculture.

        Biosecurity in Animal Production and Veterinary Medicine

        by Jeroen Dewulf, Filip Van Immerseel

        Globally, the way the animal production industry copes with infectious diseases is changing. The (excessive) use of antimicrobials is under debate and it is becoming standard practice to implement thorough biosecurity plans on farms to prevent the entry and spread of pathogenic micro-organisms. Not only in farm animal production, but also in facilities where companion animals are kept, including in veterinary practices and clinics, awareness of the beneficial implications of a good biosecurity plan has raised. The book Biosecurity in Animal Production and Veterinary Medicine is the first compilation of both fundamental aspects of biosecurity practices, and specific and practical information on the application of the biosecurity measures in different animal production and animal housing settings. The book starts with a general introductory chapter on the epidemiology of infectious diseases, followed by a chapter explaining the general principles of biosecurity. Specific topics of biosecurity, including rodent and insect control, cleaning and disinfection, hygiene and decontamination of feed, drinking water and air, and measuring the biosecurity status of farms, are detailed in dedicated chapters. Explanations on the relevance of the implementation of biosecurity plans in order to improve animal health and performance and reduce antimicrobial usage are described, and a chapter on ways to motivate farmers to implement a biosecurity plan has been included. Practical chapters deal with biosecurity in the poultry, pig and cattle industry, horse facilities, dog kennels, veterinary practices and clinics and laboratory animal facilities. The book is a practical guide that can be used by farm and animal facility managers, consultants, veterinarians, animal caretakers, and people with an interest in prevention of diseases in animals. Academics and students will benefit from the book because it contains all relevant information on animal biosecurity.

        Health Benefits of Organic Food

        Effects of the Environment

        by Edited by D I Givens, Samantha Baxter, Anne Marie Minihane, Elizabeth J Shaw.

        Public concern over impacts of chemicals in plant and animal production on health and the environment has led to increased demand for organic produce, which is usually promoted and often perceived as containing fewer contaminants, more nutrients, and being positive for the environment.These benefits are difficult to quantify, and potential environmental impacts on such benefits have not been widely studied. This book addresses these key points, examining factors such as the role of certain nutrients in prevention and promotion of chronic disease, potential health benefits of bioactive compounds in plants, the prevalence of food-borne pesticides and pathogens and how both local and global environmental factors may affect any differences between organic and conventionally produced food.With contributions from experts in a broad range of related disciplines, this book is an essential resource for researchers and students in human health and nutrition, environmental science, agriculture and organic farming.

        Global Development of Organic Agriculture

        Challenges and Prospects

        by Edited by Niels Halberg, Hugo F Alroe, Marie T Knudsen, Erik S Kristensen

        Modern agriculture and food systems, including organic agriculture, are undergoing a technological and structural modernisation and are faced with a growing globalisation. Organic agriculture (OA) can be seen as pioneering efforts to create sustainable development based on other principles than mainstream agriculture. There are however large differences between the challenges connected to, on one hand, modern farming and consumption in high-income countries and, on the other, smallholder farmers and resource poor consumers in low-income countries. The point of departure is the increasing globalisation and the production and trade of food and fodder and how this influences the role of OA. This book provides an overview of the potential role and challenges of organic agriculture in this global perspective, as seen from different perspectives such as sustainability, food security and fair trade.

        Organic Food Systems

        Meeting the Needs of Southern Africa

        by Raymond Auerbach

        Organic agriculture world-wide allows farmers to produce healthy food with low levels of external inputs, and often shortens the value chains, giving farmers a higher share of the consumer dollar. This book reports on long-term comparative organic farming systems research trials carried out over the last four years in South Africa's Southern Cape, as well as research on the organic sector and the technical tools it requires in South Africa, Zambia, Uganda and Tanzania. The trials show how the yield gap between organic and conventional crops was closed over 3 years. Water use efficiency was also greater in the organic farming system, and pests and diseases were effectively controlled using biological products. Farmer training approaches, soil carbon analysis, participatory guarantee systems, the Zambian organic farming sector (agronomy) and Ugandan organic farmer training support, and a sector plan for southern African organic farming are examined.

        Fair Trade and Organic Agriculture

        A Winning Combination?

        by Priyanka Parvathi, Ulrike Grote, Hermann Waibel, Arnab Basu, Lee Buyers, Rene Capote, Ricardo Fort, Ulrike Grote, Casey Goldvale, Ulrich Hamm, Pradyot Ranjan Jena, Linda Kleemann, Katharina Krumbiegel, Julia Lernoud, Priyanka Parvathi, Yu Hui Qiao, Ruerd Ruben, Rosa Scheenbecker, Till Stellmacher, Romane Viennet, Hermann Waibel, Helga Willer, Meike Wollni, Katrin Zander

        The markets for organic and fair trade certified commodities are growing rapidly, with environmentally sound and more equitable certification systems likely to offer benefits for both small-scale farmers and society at large. Despite much debate about their contribution to sustainability, there has been little scientific analysis, so it is vital to assess if it is technically and economically feasible to meet growing consumer demands regarding food safety, quality and ethics through smallholder and marginal producers. Overall, there is a need to explore the potential of these certification systems as emerging areas in research and development cooperation. This book includes: - Worldwide case studies (from the supply side in Asia, Africa, and Latin America; and from the demand side in Europe and North America) to put theory into practice. - Analyses of sustainable development and poverty reduction through organic and fair trade markets. - Insights into the conditions where it is beneficial for developing country smallholder producers to adopt fair trade and organic certification systems. - Investigation into whether consumers will pay more for a product that is both organic and fair trade certified. This book is an important read for researchers and students in agricultural and development economics, and it is also a useful resource for policy makers and practitioners involved in organic and fair trade agriculture.

        With organic pioneer Ulrich Walter through five decades

        by Heike Leitschuh

        The small district town of Diepholz lies between Bremen, Oldenburg and Osnabrück, and no one could possibly describe it as “well-known”. Quite unlike the Lebensbaum company, which was founded here by Ulrich Walter in 1979. Those who eat mindfully will probably also be familiar with the coffees, teas and spices of this pioneering organic company, which frequently and repeatedly receives a range of awards for sustainability and now employs around 200 people. Heike Leitschuh draws a lifelike portrait of an entrepreneur of the organic founding generation who turned a small shop into a successful medium-sized company, played a key role in shaping the organic industry, and has offered perspectives for its future.

        by Edited by Benjamin L Turner, Emmanuel Frossard, Darren S Baldwin

        Organic phosphorus is involved in almost every biological process. Organic forms of phosphorus often dominate in soils and aquatic systems and many organisms possess complex mechanisms enabling them to access phosphorus from organic compounds. However organic phosphorus remains the most poorly understood aspect of the global phosphorus cycle. This book brings together the latest research and opinion on the biogeochemistry of organic phosphorus from a wide range of disciplines and focuses specifically on the characterisation and transformations of organic phosphorus in terrestrial and aquatic systems. It examines analytical procedures for the chemical characterization of organic phosphorus in environmental samples, processes regulating organic phosphorus in the environment, and integration of the process at the ecosystem level. Ecological, chemical, microbiological and analytical aspects are explored. Written by a team of leading experts, the book will provide an invaluable reference for all those interested in organic phosphorus.
