Download or read book LED Lighting for Urban Agriculture written by Toyoki Kozai and published by Springer. This book was released on 2016-11-08 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on light-emitting diode (LED) lighting, mainly for the commercial production of horticultural crops in plant factories and greenhouses with controlled environments, giving special attention to: 1) plant growth and development as affected by the light environment; and 2) business and technological opportunities and challenges with regard to LEDs. The book contains more than 30 chapters grouped into seven parts: 1) overview of controlled-environment agriculture and its significance; 2) the effects of ambient light on plant growth and development; 3) optical and physiological characteristics of plant leaves and canopies; 4) greenhouse crop production with supplemental LED lighting; 5) effects of light quality on plant physiology and morphology; 6) current status of commercial plant factories under LED lighting; and 7) basics of LEDs and LED lighting for plant cultivation. LED lighting for urban agriculture in the forthcoming decades will not be just an advanced form of current urban agriculture. It will be largely based on two fields: One is a new paradigm and rapidly advancing concepts, global technologies for LEDs, information and communication technology, renewable energy, and related expertise and their methodologies; the other is basic science and technology that should not change for the next several decades. Consideration should be given now to future urban agriculture based on those two fields. The tremendous potentials of LED lighting for urban agriculture are stimulating many people in various fields including researchers, businesspeople, policy makers, educators, students, community developers, architects, designers, and entrepreneurs. Readers of this book will understand the principle, concept, design, operation, social roles, pros and cons, costs and benefits of LED lighting for urban agriculture, and its possibilities and challenges for solving local as well as global agricultural, environmental, and social issues.
Download or read book Colleges of Agriculture at the Land Grant Universities written by National Research Council and published by National Academies Press. This book was released on 1995-10-27 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although few Americans work as farmers these days, agriculture on the whole remains economically importantâ€"playing a key role in such contemporary issues as consumer health and nutrition, worker safety and animal welfare, and environmental protection. This publication provides a comprehensive picture of the primary education system for the nation's agriculture industry: the land grant colleges of agriculture. Colleges of Agriculture at the Land Grant Universities informs the public debate about the challenges that will shape the future of these colleges and serves as a foundation for a second volume, which will present recommendations for policy and institutional changes in the land grant system. This book reviews the legislative history of the land grant system from its establishment in 1862 to the 1994 act conferring land grant status on Native American colleges. It describes trends that have shaped agriculture and agricultural education over the decadesâ€"the shift of labor from farm to factory, reasons for and effects of increased productivity and specialization, the rise of the corporate farm, and more. The committee reviews the system's three-part missionâ€"education, research, and extension serviceâ€"and through this perspective documents the changing nature of funding and examines the unique structure of the U.S. agricultural research and education system. Demographic data on faculties, students, extension staff, commodity and funding clusters, and geographic specializations profile the system and identify similarities and differences among the colleges of agriculture, trends in funding, and a host of other issues. The tables in the appendix provide further itemization about general population distribution, student and educator demographics, types of degree programs, and funding allocations. Concise commentary and informative graphics augment the detailed statistical presentations. This book will be important to policymakers, administrators, educators, researchers, and students of agriculture.
Download or read book The Fault Lines of Farm Policy written by Jonathan Coppess and published by University of Nebraska Press. This book was released on 2018-12-01 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: At the intersection of the growing national conversation about our food system and the long-running debate about our government’s role in society is the complex farm bill. American farm policy, built on a political coalition of related interests with competing and conflicting demands, has proven incredibly resilient despite development and growth. In The Fault Lines of Farm Policy Jonathan Coppess analyzes the legislative and political history of the farm bill, including the evolution of congressional politics for farm policy. Disputes among the South, the Great Plains, and the Midwest form the primordial fault line that has defined the debate throughout farm policy’s history. Because these regions formed the original farm coalition and have played the predominant roles throughout, this study concentrates on the three major commodities produced in these regions: cotton, wheat, and corn. Coppess examines policy development by the political and congressional interests representing these commodities, including basic drivers such as coalition building, external and internal pressures on the coalition and its fault lines, and the impact of commodity prices. This exploration of the political fault lines provides perspectives for future policy discussions and more effective policy outcomes.
Download or read book Economics of Research and Innovation in Agriculture written by Petra Moser and published by University of Chicago Press. This book was released on 2021-10-08 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The challenges facing agriculture are plenty. Along with the world's growing population and diminishing amounts of water and arable land, the gradual increase in severe weather presents new challenges and imperatives for producing new, more resilient crops to feed a more crowded planet in the twenty-first century. Innovation has historically helped agriculture keep pace with earth's social, population, and ecological changes. In the last 50 years, mechanical, biological, and chemical innovations have more than doubled agricultural output while barely changing input quantities. The ample investment behind these innovations was available because of a high rate of return: a 2007 paper found that the median ROI in agriculture was 45 percent between 1965 and 2005. This landscape has changed. Today many of the world's wealthier countries have scaled back their share of GDP devoted to agricultural R&D amid evidence of diminishing returns. Universities, which have historically been a major source of agricultural innovation, increasingly depend on funding from industry rather than government to fund their research. As Upton Sinclair wrote of the effects industry influences, "It is difficult to get a man to understand something when his salary depends upon his not understanding it." In this volume of the NBER Conference Report series, editor Petra Moser offers an empirical, applied-economic framework to the different elements of agricultural R&D, particularly as they relate to the shift from public to private funding. Individual chapters examine the sources of agricultural knowledge and investigate challenges for measuring the returns to the adoption of new agricultural technologies, examine knowledge spillovers from universities to agricultural innovation, and explore interactions between university engagement and scientific productivity. Additional analysis of agricultural venture capital point to it as an emerging and future source of resource in this essential domain"--

Download or read book Soil Phosphorus written by Rattan Lal and published by CRC Press. This book was released on 2016-09-19 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phosphorus is an essential plant nutrient, but global population growth has dramatically reduced the availability of phosphorus fertilizer resources. Despite this scarcity, there remain numerous problems associated with the excessive and inappropriate use of phosphorus leading to non-point source pollution and eutrophication of natural waters. Identifying appropriate systems for managing soil phosphorus and reducing the risks of eutrophication are needed to minimize the environmental risks. This book focuses on the availability and recycling of phosphorus; regulatory and policy issues of sustainable phosphorus use; and water quality management in agroecosystems pertaining to phosphorus. Sections are dedicated to global phosphorus reserves; cycling and pathways of phosphorus; phosphorus in agriculture; human dimensions and policy intervention; and research and development priorities. Phosphorus is a finite but crucial resource and is an essential element to all life. Sub-optimal availability and nutrient imbalance in the root zone can adversely impact plant growth, and the quality of food and feed grown on these soils. However, the proven reserves of phosphorus can hardly be adequate for a few centuries only. Yet, its misuse and mismanagement has caused severe problems of eutrophication of water and pollution of the environment. Thus, judicious management of soil phosphorus is essential. This volume is specifically devoted to availability and recycling of phosphorus, regulatory/policy issues of sustainable use of phosphorus, and management in agroecosystems in the context of maximizing the use efficiency and minimizing the environmental risks of water quality.

Download or read book Status of Pollinators in North America written by National Research Council and published by National Academies Press. This book was released on 2007-05-13 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pollinators-insects, birds, bats, and other animals that carry pollen from the male to the female parts of flowers for plant reproduction-are an essential part of natural and agricultural ecosystems throughout North America. For example, most fruit, vegetable, and seed crops and some crops that provide fiber, drugs, and fuel depend on animals for pollination. This report provides evidence for the decline of some pollinator species in North America, including America's most important managed pollinator, the honey bee, as well as some butterflies, bats, and hummingbirds. For most managed and wild pollinator species, however, population trends have not been assessed because populations have not been monitored over time. In addition, for wild species with demonstrated declines, it is often difficult to determine the causes or consequences of their decline. This report outlines priorities for research and monitoring that are needed to improve information on the status of pollinators and establishes a framework for conservation and restoration of pollinator species and communities.

Download or read book Space Time Colonialism written by Juliana Hu Pegues and published by UNC Press Books. This book was released on 2021-05-11 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the enduring "last frontier," Alaska proves an indispensable context for examining the form and function of American colonialism, particularly in the shift from western continental expansion to global empire. In this richly theorized work, Juliana Hu Pegues evaluates four key historical periods in U.S.-Alaskan history: the Alaskan purchase, the Gold Rush, the emergence of salmon canneries, and the World War II era. In each, Hu Pegues recognizes colonial and racial entanglements between Alaska Native peoples and Asian immigrants. In the midst of this complex interplay, the American colonial project advanced by differentially racializing and gendering Indigenous and Asian peoples, constructing Asian immigrants as "out of place" and Alaska Natives as "out of time." Counter to this space-time colonialism, Native and Asian peoples created alternate modes of meaning and belonging through their literature, photography, political organizing, and sociality. Offering an intersectional approach to U.S. empire, Indigenous dispossession, and labor exploitation, Space-Time Colonialism makes clear that Alaska is essential to understanding both U.S. imperial expansion and the machinations of settler colonialism.
