Summary : The use of plastics in agriculture – to increase crop output, improve food quality and improve sustainability – has grown substantially in both quantity and the range of applications. Many of the early researchers that conducted field research in the use of plastics in agriculture have either retired or are deceased. These early pioneers in plasticulture research, the basis of plant production using plastics, were very creative and persistent in discovering uses of plastics in agricultural applications. A Guide to the Manufacture, Performance, and Potential of Plastics in Agriculture contains both references not only to their accomplishments but also their publications. The book discusses plasticulture-the basis of plant production using plastics – including topics such as plastic mulch, row covers, drip irrigation, and high/low tunnels. It covers the process of producing polyethylene and polypropylene plastics that are used in plant and animal production agriculture, and the many uses of plastics in all aspects of agriculture, including plastic greenhouses, rigid mold plastics, disposal of plastics, and plastics in animal production. This book introduces a range of academics and industrial practitioners to the impact of plastics in agriculture, both historically and in a range of current applications. It also provides new perspectives on future developments to enable further research and application. It is an invaluable reference on the use of polyethylene, polypropylene films, and such products in all aspects of agricultural production. Discusses plasticulture, the basis of plant production using plastics, including topics such as plastic mulch, row covers, drip irrigation, and high/low tunnels Contains 10 chapters that cover the process of producing polyethylene and polypropylene plastics that are used in agriculture Covers the many uses of plastics in all aspects of agriculture, including plastic greenhouses, rigid mold plastics, disposal of plastics, and plastics in animal production

Summary : This book presents an exhaustive analysis of the trends in the development and use of natural and synthetic polymer systems aimed at sustainable agricultural production. The polymers have allowed the development of controlled and released systems of agrochemicals such as pesticides, fertilizers and phytohormones through micro and nanoencapsulated systems, which protect and stimulate the growth of crops at low costs and without damage to the environment. Hydrogel systems from natural and synthetic polymers have also had their place in the agricultural industry, since they allow to maintain the humidity conditions of the crops for their correct development in drought times. Mulch films made of polymers have also become important in the control of weeds and pests in crops, as well as the use of edible coatings applied to fruits and vegetables during post-harvest, which reduce the losses of these perishable foods. Currently, the systems indicated, as well as others, are already used on a large scale. However, research studies in this area have been limited compared to other polymer applications. This book collects useful information for researchers, students and technologies related to the polymer technology and agri-food production. In this book, world-renowned researchers have participated, including associate editors of important journals, as well as researchers working in the area of research and development (R&D) of leading agri-food industries in the manufacture of agricultural inputs.

Summary : This book describes how man-made litter, primarily plastic, has spread into the remotest parts of the oceans and covers all aspects of this pollution problem from the impacts on wildlife and human health to socio-economic and political issues. Marine litter is a prime threat to marine wildlife, habitats and food webs worldwide. The book illustrates how advanced technologies from deep-sea research, microbiology and mathematic modelling as well as classic beach litter counts by volunteers contributed to the broad awareness of marine litter as a problem of global significance. The authors summarise more than five decades of marine litter research, which receives growing attention after the recent discovery of great oceanic garbage patches and the ubiquity of microscopic plastic particles in marine organisms and habitats. In 16 chapters, authors from all over the world have created a universal view on the diverse field of marine litter pollution, the biological impacts, dedicated research activities, and the various national and international legislative efforts to combat this environmental problem. They recommend future research directions necessary for a comprehensive understanding of this environmental issue and the development of efficient management strategies. This book addresses scientists, and it provides a solid knowledge base for policy makers, NGOs, and the broader public.

Summary : Best practices for the eight most profitable crops Today only a few dozen large-scale producers dominate the greenhouse produce market. Why? Because they know and employ best practices for the most profitable crops: tomatoes, eggplant, cucumbers, peppers, leafy greens, lettuce, herbs, and microgreens. The Greenhouse and Hoophouse Grower's Handbook levels the playing field by revealing these practices so that all growers--large and small--can maximize the potential of their protected growing space. Whether growing in a heated greenhouse or unheated hoophouse, this book offers a decision-making framework for how to best manage crops that goes beyond a list of simple do's and don'ts. As senior trial technician for greenhouse crops at Johnny's Selected Seeds, author Andrew Mefferd spent seven years consulting for growers using protected agriculture in a wide variety of climates, soils, and conditions. The Greenhouse and Hoophouse Grower's Handbook brings his experience and expertise to bear in an in-depth guide that will help readers make their investment in greenhouse space worthwhile. Every year, more growers are turning to protected culture to deal with unpredictable weather and to meet out-of-season demand for local food, but many end up spinning their wheels, wasting time and money on unprofitable crops grown in ways that don't make the most of their precious greenhouse space. With comprehensive chapters on temperature control and crop steering, pruning and trellising, grafting, and more, Mefferd's book is full of techniques and strategies that can help farms stay profitable, satisfy customers, and become an integral part of re-localizing our food system. From seed to sale, The Greenhouse and Hoophouse Grower's Handbook is the indispensable resource for protected growing.

Summary : The need to reduce food loss and waste is firmly embedded in the 2030 Agenda for Sustainable Development. Food loss and waste reduction is considered important for improving food security and nutrition, promoting environmental sustainability and lowering production costs. However, efforts to reduce food loss and waste will only be effective if informed by a solid understanding of the problem. This report provides new estimates of the percentage of the world’s food lost from production up to the retail level. The report also finds a vast diversity in existing estimates of losses, even for the same commodities and for the same stages in the supply chain. Clearly identifying and understanding critical loss points in specific supply chains – where considerable potential exists for reducing food losses – is crucial to deciding on appropriate measures. The report provides some guiding principles for interventions based on the objectives being pursued through food loss and waste reductions, be they in improved economic efficiency, food security and nutrition, or environmental sustainability.

Summary : Asthma, allergy and chronic obstructive lung disease are common throughout the world and are increasing in incidence, particularly in the developing world. This volume provides a state-of-the-art account of the identification of new targets and the development of new therapies for these conditions. Some 40 chapters by clinical academics and senior members of the pharmaceutical industry detail the latest breakthroughs in research and development. In asthma, a promising approach is the use of therapy directed against specific Th2 responses through biological antagonists of IL-5, IL-4 and IL-13. There have also been major advances in our understanding of innate immune responses to pathogen-associated molecular patterns, and in the area of Toll-like receptors. Up to date and comprehensive, this book will be of particular relevance to those working in the pharmaceutical industry (in preclinical research and clinical development), to academic researchers in the field of respiratory medicine, and to respiratory health care specialists.

Summary : • New York Times bestseller • The 100 most substantive solutions to reverse global warming, based on meticulous research by leading scientists and policymakers around the world “At this point in time, the Drawdown book is exactly what is needed; a credible, conservative solution-by-solution narrative that we can do it. Reading it is an effective inoculation against the widespread perception of doom that humanity cannot and will not solve the climate crisis. Reported by-effects include increased determination and a sense of grounded hope.” —Per Espen Stoknes, Author, What We Think About When We Try Not To Think About Global Warming “There’s been no real way for ordinary people to get an understanding of what they can do and what impact it can have. There remains no single, comprehensive, reliable compendium of carbon-reduction solutions across sectors. At least until now. . . . The public is hungry for this kind of practical wisdom.” —David Roberts, Vox “This is the ideal environmental sciences textbook—only it is too interesting and inspiring to be called a textbook.” —Peter Kareiva, Director of the Institute of the Environment and Sustainability, UCLA In the face of widespread fear and apathy, an international coalition of researchers, professionals, and scientists have come together to offer a set of realistic and bold solutions to climate change. One hundred techniques and practices are described here—some are well known; some you may have never heard of. They range from clean energy to educating girls in lower-income countries to land use practices that pull carbon out of the air. The solutions exist, are economically viable, and communities throughout the world are currently enacting them with skill and determination. If deployed collectively on a global scale over the next thirty years, they represent a credible path forward, not just to slow the earth’s warming but to reach drawdown, that point in time when greenhouse gases in the atmosphere peak and begin to decline. These measures promise cascading benefits to human health, security, prosperity, and well-being—giving us every reason to see this planetary crisis as an opportunity to create a just and livable world.
