Techniques and systems for processing food scraps, manure, yard debris, paper, and more Turning waste into wealth sounds too good to be true, but many worm farmers are finding that vermicomposting is a reliable way to do just that. Vermicast--a biologically active, nutrient-rich mix of earthworm castings and decomposed organic matter--sells for $400 or more per cubic yard. Compare that to regular compost, sold at about $30 a cubic yard, and you'll see why vermicomposting has taken root in most countries and on every continent but Antarctica. Vermicomposting is also one of the best sustainable solutions for organic waste management. Vermicomposting manure and crop wastes on farms improves crop yields while reducing demand for off-farm inputs. Vermicast has higher nutrient levels and lower soluble salt content than regular compost, and it improves soil aeration, porosity, and water retention. Plus, vermicast suppresses plant diseases and insect attacks. Municipalities, businesses, community gardens, schools, and universities can set up vermicomposting operations to process food residuals and other waste materials. The Worm Farmer's Handbook details the ins and outs of vermicomposting for mid- to large-scale operations, including how to recycle organic materials ranging from food wastes and yard trimmings to manure and shredded office paper. Vermicomposting expert Rhonda Sherman shares what she has learned over twenty-five years working with commercial worm growers and researchers around the world. Her profiles of successful worm growers across the United States and from New Zealand to the Middle East and Europe describe their proven methods and systems. This book digs into all the details, including: Choosing the right production system Regulatory issues and developing a business and marketing plan Finding and managing feedstocks Pre-composting: why and how to do it Monitoring an active worm bed Harvesting, screening, testing, packaging, and storing vermicast Markets for earthworms and vermicast Food security: how vermicast benefits soils and plants Keys to success: avoiding common pitfalls From livestock farms and restaurants to colleges, military bases, and prisons, Sherman details why and how commercial-scale vermicomposting is a fast-growing, sustainable solution for organic waste management. The Worm Farmer's Handbook is the first and only authoritative how-to guide that goes beyond small-scale operations and demystifies the science and logistics of the fascinating process that is vermicomposting.

An Unlikely Vineyard - The Education of a Farmer and Her Quest for Terroir (Paperback): Deirdre Heekin An Unlikely Vineyard - The Education of a Farmer and Her Quest for Terroir (Paperback)

Named one of the Best Wine Books of 2014 by The New York Times, An Unlikely Vineyard tells the evolutionary story of Deirdre Heekin's farm from overgrown fields to a fertile, productive, and beautiful landscape that melds with its natural environment. Is it possible to capture landscape in a bottle? To express its terroir, its essence of place--geology, geography, climate, and soil--as well as the skill of the winegrower? That's what Heekin and her chef/husband, Caleb Barber, set out to accomplish on their tiny, eight-acre hillside farm and vineyard in Vermont. But An Unlikely Vineyard involves much more. It also presents, through the example of their farming journey and winegrowing endeavors, an impressive amount of information on how to think about almost every aspect of gardening: from composting to trellising; from cider and perry making to growing old garden roses, keeping bees, and raising livestock; from pruning (or not) to dealing naturally with pests and diseases. As Eric Asimov, chief wine critic for The New York Times, writes, "I love this book, which conveys beautifully why the best wine is, at heart, an agricultural expression." Challenged by cold winters, wet summers, and other factors, Deirdre and Caleb set about to grow not only a vineyard, but an orchard of heirloom apples, pears, and plums, as well as gardens filled with vegetables, herbs, roses, and wildflowers destined for their own table and for the kitchen of their small restaurant. They wanted to create, or rediscover, a sense of place, and to grow food naturally using the philosophy and techniques gleaned from organic gardening, permaculture, and biodynamic farming. Accompanied throughout by lush photos, this gentle narrative will appeal to anyone who loves food, farms, and living well.

Sustainability of Organic Farming in Nepal (Hardcover, 1st ed. 2017): Mrinila Singh, Keshav Lall Maharjan Sustainability of Organic Farming in Nepal (Hardcover, 1st ed. 2017)

R3,120 R2,807 Discovery Miles 28 070 Save R313 (10%) Shipped within 7 - 12 working days

This book explores the sustainability aspect of organic and conventional farming systems, which is commonly categorized into three sub-aspects: social, environmental and economic. The social structure of a given area, organic friendly technologies, soil properties, crop diversification and income are the elements chosen for comparison, and are analyzed using descriptive and statistical methods. In addition, the book assesses the current status of the local organic market in Nepal and field experiments involving the use of various organic means to achieve better production for selected vegetables. Determining the benefits and/or challenges of organic and conventional farming is important to determining the most viable type of farming in the long term, but can be greatly impacted by a given area's specific characteristics (social, environmental, political, etc.), which is why this study focuses on a specific location: the Chitwan district of Nepal, where group conversion to organic farming has existed alongside conventional farming for years. This book offers a useful guide for both practitioners and academic researchers who are interested in organic farming and food security, particularly in developing countries.

This book introduces readers to nearly 600 common weeds. In addition to essential information, each chapter includes photos for a specific type of weed to show its morphology in different growth periods, such as seedling, root, flower, fruit, and mature plant. The book also discusses control measures, including agricultural, chemical, physical, biological, and comprehensive methods. The Volume 3 mainly focuses on 252 Species of Dicotyledonous and Monocotyledonous Weeds along with 2 Species of Liverworts and Mosses. With the development of society and economics, weeds have become a recurring problem. In particular, the exotic, invasive, and quarantine weeds have spread dramatically and rapidly. On the other hand, many people, even those who are engaged in weed control, do not (or cannot) distinguish between weeds. Thus there is significant demand for illustrations of weed morphologies, as well as information on their control measures. This book offers a valuable, practical guide for all those working in the fields of crop cultivation, plant protection and quarantine management.

"Daniel Pauly is a friend whose work has inspired me for years." --Ted Danson, actor, ocean activist, and co-author of Oceana "This wonderfully personal and accessible book by the world's greatest living fisheries biologist summarizes and expands on the causes of collapse and the essential actions that will be required to rebuild fish stocks for future generations." --Dr. Jeremy Jackson, ocean scientist and author of Breakpoint The world's fisheries are in crisis. Their catches are declining, and the stocks of key species, such as cod and bluefin tuna, are but a small fraction of their previous abundance, while others have been overfished almost to extinction. The oceans are depleted and the commercial fishing industry increasingly depends on subsidies to remain afloat. In these essays, award-winning biologist Dr. Daniel Pauly offers a thought-provoking look at the state of today's global fisheries--and a radical way to turn it around. Starting with the rapid expansion that followed World War II, he traces the arc of the fishing industry's ensuing demise, offering insights into how and why it has failed. With clear, convincing prose, Dr. Pauly draws on decades of research to provide an up-to-date assessment of ocean health and an analysis of the issues that have contributed to the current crisis, including globalization, massive underreporting of catch, and the phenomenon of "shifting baselines," in which, over time, important knowledge is lost about the state of the natural world. Finally, Vanishing Fish provides practical recommendations for a way forward--a vision of a vibrant future where small-scale fisheries can supply the majority of the world's fish.

This book reviews the latest developments in our understanding of microbial endophytes and their potential applications in enhancing productivity and disease protection. It covers all the latest discoveries regarding endophytes, their interactions with plants and application in agricultural productivity and protection. Our understanding of endophytes has increased exponentially in recent decades. These microbes, such as fungi, bacteria, and actinobacteria, establish a symbiotic or parasitic association with plants. A better understanding of endophytic microorganisms may help to elucidate their functions and potential role in developing sustainable systems of crop production and improved protection against biotic stresses. Endophytes play a vital role in plant growth and health promotion. Endophytic bacteria are of agrobiological interest because they create host-endophyte relationships, which can open exciting prospects for newer biotechnological applications. Endophytes have also proven to be a beneficial and sustainable alternative to agrochemicals due to their role in the biocontrol of pests and diseases. Further, endophytes are essential to the production of several secondary metabolites in grasses, in the process of gummosis in trees, and the production of useful metabolites such as alkaloids, pestaloside, cryptocandin, enfumafungin, subglutinols, etc. for the host plant. They are also involved in the production of enzymes, biosurfactants, biocontrol agents and plant growth promoters. As such, it is imperative that we explore these products' industrial applications in the fields of biotechnology, pharmacy and agriculture. This volume will offers a valuable guidance for botanists, microbiologists, biotechnologists, molecular biologists, environmentalists, policymakers, conservationists, and those working for the protection of plant species of agricultural and medicinal importance.

R2,183 Discovery Miles 21 830 Shipped within 7 - 12 working days

In large parts of the world, the reduction in the viability of agriculture and rural areas is an escalating problem. Sustainable Land Management offers a contemporary overview of the strategies employed to cope with the marginalisation of agriculture, through analyses of case studies and regional trends in marginalisation. The authors argue that complexities and driving forces governing marginalisation are not always the same across nations and regions due to climate, geography, economics, legislation and political status. This book illustrates in what form these complexities exist, and how these unravel at the national and regional levels. As the need to understand and cope with marginalisation processes has developed, the concept of multi-functionality has also gained a vital place in the string of coping strategies. This work contributes essential knowledge for the development of marginalisation mitigation policy actions across the globe. Informative and well-documented, this book will appeal to those researching and working in the fields of agricultural and resource economics, rural geography, environmental governance and sustainable development.

Agriculture is currently facing multi-faceted threats in the form of unpredictable weather variability, frequent droughts and scarcity of irrigation water, together with the degradation of soil resources and declining environmental health. These stresses result in the modification of plant physiology to impart greater resilience to changing abiotic and biotic environments, but only at the cost of declining plant productivity. In light of these facts, assessing the status of natural resource bases, and understanding the mechanisms of soil-plant-environment interactions so as to devise adaptation and mitigation approaches, represent great and imminent challenges for all of us. In this context, it is essential to understand the potential applications of modern tools, existing coping mechanisms and their integration, as this will allow us to develop suitable advanced mitigation strategies. From a broader perspective, the book deals with crop-environment interaction in the context of changing climatic conditions. To do so, it addresses four major aspects: Understanding the mechanism of carbon dynamics in the soil-plant-environment continuum; greenhouse gas fluxes in agricultural systems; and soil properties influenced by climate change and carbon sequestration processes. Mitigation and management of the photo-thermal environment to improve crop productivity; soil health under variable climate; reducing agro-ecosystem evapotranspiration losses through biophysical controls; and heat stress in field crops and its management. Studying the impact of climate change on biotic environments; insect-pest interactions; manifestations of disease; and adaptation strategies for island agro-ecosystems. Innovative approaches to assess stress impacts in crops, such as crop modeling, remote sensing, spectral stress indices etc. The book presents a collection of contributions from authoritative experts in their respective fields. Offering young researchers new perspectives and future research directions, it represents a valuable guide for graduate students and academics alike.

GM Food on Trial - Testing European Democracy (Paperback): Les Levidow, Susan Carr GM Food on Trial - Testing European Democracy (Paperback)
Les Levidow, Susan Carr
R778 Discovery Miles 7 780 Shipped within 7 - 12 working days

Europe was told that it had no choice but to accept agbiotech, yet this imperative was turned into a test of democratic accountability for societal choices. Since the late 1990s, European public controversy has kept the agri-biotech industry and its promoters on the defensive. As some opponents and regulators alike have declared, 'GM food/crops are on trial'. Suspicion of their guilt has been evoked by moral symbols, as disputes over whether genetically-modified products are modest benign improvements on traditional plant breeding, or dangerous Frankenfoods; and in disputes over whether they are global saviours, or control agents of multinational companies. This book examines European institutions being 'put on trial' for how their regulatory procedures evaluate and regulate GM products, in ways which opened up alternative futures. Levidow and Carr highlight how public controversy created a legitimacy crisis, leading to national policy changes and demands, in turn stimulating changes in EU agbiotech regulations as a strategy to regain legitimacy.

R792 Discovery Miles 7 920 Shipped within 7 - 12 working days

The Common Agricultural Policy (CAP) is a unique agricultural policy worldwide. For many years, its status as the only common European Community (EC) policy governed by EC institutions put it at the heart of European integration. Today the CAP is not the only common European Union (EU) policy. Even while it remains the sole instance of a regionally integrated agricultural policy, the CAP no longer embodies the same degree of cross-national harmonization of agricultural policy among EC/EU member states that it once did. The CAP has undergone policy reforms in the past two decades and these reforms have spawned a host of questions. What has caused the CAP to reform? How path-breaking are CAP reforms? Are they consistent with founding CAP goals or do they encompass new ideas about agriculture's place in the economy and society? And what are the consequences of agricultural policy reforms: for European farmers, consumers and taxpayers; for European `public goods' such as environmental sustainability and preservation of rural communities and landscapes; and for third parties outside the EU, including the WTO? This book was published as a special issue of the Journal of European Integration.

Tropical fruits such as banana, mango, papaya, and pineapple are familiar and treasured staples of our diets, and consequently of great commercial importance, but there are many other interesting species that are little known to inhabitants of temperate regions. What delicacies are best known only by locals? The tropical regions are home to a vast variety of edible fruits, tubers, and spices. Of the more than two thousand species that are commonly used as food in the tropics, only about forty to fifty species are well known internationally. Illustrated with high-quality photographs taken on location in the plants' natural environment, this field guide describes more than three hundred species of tropical and subtropical species of fruits, tubers, and spices. In Tropical Fruits and Other Edible Plants of the World, Rolf Blancke includes all the common species and features many lesser known species, including mangosteen and maca, as well as many rare species such as engkala, sundrop, and the mango plum. Some of these rare species will always remain of little importance because they need an acquired taste to enjoy them, they have too little pulp and too many seeds, or they are difficult to package and ship. Blancke highlights some fruits--the araza (Eugenia stipitata) and the nutritious peach palm (Bactris gasipaes) from the Amazon lowlands, the Brunei olive (Canarium odontophyllum) from Indonesia, and the remarkably tasty soursop (Annona muricata) from Central America--that deserve much more attention and have the potential to become commercially important in the near future. Tropical Fruits and Other Edible Plants of the World also features tropical plants used to produce spices, and many tropical tubers, including cassava, yam, and oca. These tubers play a vital role in human nutrition and are often foundational to the foodways of their local cultures, but they sometimes require complex preparation and are often overlooked or poorly understood distant from their home context.
