Rebels for the Soil: The Rise of the Global Organic Food and Farming Movement
by Matthew ReedThis book investigates the emergence of organic food and farming as a social movement. Using the tools of political sociology it analyzes and explains how both people and ideas have shaped a movement that from its inception aimed to change global agriculture. Starting from the British Empire in the 1930's, where the first trans-national roots of organic farming took hold, through to the internet-mediated social protests against genetically modified crops at the end of the twentieth century, the author traces the rise to prominence of the movement. As well as providing a historical account, the book explains the movement's on-going role in fostering and organising alternatives to the dominant intensive and industrial forms of agriculture, such as promoting local food produce and animal welfare. By considering it as a trans-national movement from its inception, aiming at cultural and social change, the book highlights what is unique about the organic movement and why it has risen only relatively recently to public attention. The author reports original research findings, focusing largely on the English-speaking world. The work is grounded in academic enquiry and theory, but also provides a narrative through which the movement can be understood by the more general interested reader.
Rebooting AI: Building Artificial Intelligence We Can Trust
by Gary Marcus Ernest DavisTwo leaders in the field offer a compelling analysis of the current state of the art and reveal the steps we must take to achieve a truly robust artificial intelligence.Despite the hype surrounding AI, creating an intelligence that rivals or exceeds human levels is far more complicated than we have been led to believe. Professors Gary Marcus and Ernest Davis have spent their careers at the forefront of AI research and have witnessed some of the greatest milestones in the field, but they argue that a computer beating a human in Jeopardy! does not signal that we are on the doorstep of fully autonomous cars or superintelligent machines. The achievements in the field thus far have occurred in closed systems with fixed sets of rules, and these approaches are too narrow to achieve genuine intelligence. The real world, in contrast, is wildly complex and open-ended. How can we bridge this gap? What will the consequences be when we do? Taking inspiration from the human mind, Marcus and Davis explain what we need to advance AI to the next level, and suggest that if we are wise along the way, we won't need to worry about a future of machine overlords. If we focus on endowing machines with common sense and deep understanding, rather than simply focusing on statistical analysis and gatherine ever larger collections of data, we will be able to create an AI we can trust—in our homes, our cars, and our doctors' offices. Rebooting AI provides a lucid, clear-eyed assessment of the current science and offers an inspiring vision of how a new generation of AI can make our lives better.

Rebuilding After Disasters: From Emergency to Sustainability
by Gonzalo Lizarralde Cassidy Johnson Colin DavidsonDisasters are not natural. Natural events such as earthquakes, floods, hurricanes, etc. become disasters because of the fragile relations that exist between the natural, human and built environments. Sadly, major disasters will always occur in towns and cities in the developing world where resources are limited, people are vulnerable and needs are particularly great. The prevailing state of emergency challenges thoughtful and sustainable planning and construction. Yet it is possible, in theory and in practice, to construct them in a way that provides a sustainable environment and improved conditions for current and future generations. Rebuilding After Disasters emphasizes the role of the built environment in the re-establishment of lives and sustainable livelihoods after disasters. Expert contributors explain the principal challenges facing professionals and practitioners in the building industry. This book will be of great value to decision makers, students and researchers in the fields of architecture, social sciences, engineering, planning, geography, and disaster recovery.
Rebuilding The Research Capacity At Hud
by National Research Council of the National AcademiesToday, the nation faces an array of housing and urban policy challenges. No federal department other than HUD focuses explicitly on the well-being of urban places or on the spatial relationships among people and economic activities in urban areas. If HUD, Congress, mayors, and other policy makers are to respond effectively to urban issues, they need a much more robust and effective Office of Policy Development and Research (PD&R). PD&R conducts independent research and program evaluation, funds data collection and research by outside organizations, and provides policy advice to the Secretary and to other offices in HUD. Most of PD&R’s work is of high quality, relevant, timely, and useful. With adequate resources, PD&R could lead the nation’s ongoing process of learning, debate, and experimentation about critical housing and urban development challenges. Rebuilding the Research Capacity at HUD makes seven major recommendations about PD&R’s resources and responsibilities, including more active engagement with policy makers, formalizing various informal practices, strengthening surveys and data sets, and more. Acknowledging that the current level of funding for PD&R is inadequate, the book also makes several additional recommendations to help enable PD&R to reach its full potential.
Rebuilding the Earth: Regenerating our planet’s life support systems for a sustainable future
by Mark EverardRebuilding the Earth highlights humanity’s interdependence with the planet’s ecosystems. Today, these ecosystems are seriously degraded, compromising future security and opportunity. It is essential that we set about rebuilding the metaphorical ‘ark’ of nature upon which our future prospects depend. Central to this book are several case studies of regenerative approaches drawn from every continent on the planet. These approaches are founded on restoration and protection of ecosystems – water and soil, forests, marine and coastal resources, urban infrastructure, farming practices and in corporate supply chains. Rebuilding the Earth is above all optimistic about the daunting challenges facing global society. It is about culture change, addressing the necessity of and the means for putting nature and people back into the heart of societal thinking, policy and action. It advocates for sustainable development in its deepest green sense, but also pragmatically framed in social, technological, governance and economic contexts. The concluding message is “Yes, we can!”
Rebuilding the Foodshed: How to Create Local, Sustainable, and Secure Food Systems
by Philip Ackerman-LeistDroves of people have turned to local food as a way to retreat from our broken industrial food system. From rural outposts to city streets, they are sowing, growing, selling, and eating food produced close to home-and they are crying out for agricultural reform. All this has made "local food" into everything from a movement buzzword to the newest darling of food trendsters. But now it's time to take the conversation to the next level. That's exactly what Philip Ackerman-Leist does in Rebuilding the Foodshed, in which he refocuses the local-food lens on the broad issue of rebuilding regional food systems that can replace the destructive aspects of industrial agriculture, meet food demands affordably and sustainably, and be resilient enough to endure potentially rough times ahead. Changing our foodscapes raises a host of questions. How far away is local? How do you decide the size and geography of a regional foodshed? How do you tackle tough issues that plague food systems large and small-issues like inefficient transportation, high energy demands, and rampant food waste? How do you grow what you need with minimum environmental impact? And how do you create a foodshed that's resilient enough if fuel grows scarce, weather gets more severe, and traditional supply chains are hampered?Showcasing some of the most promising, replicable models for growing, processing, and distributing sustainably grown food, this book points the reader toward the next stages of the food revolution. It also covers the full landscape of the burgeoning local-food movement, from rural to suburban to urban, and from backyard gardens to large-scale food enterprises.

Recall!: California's Political Earthquake
by Larry N. Gerston Terry ChristensenIn politics, as in so many other areas, California is unique. The state's economy - the largest in the nation, and sixth largest in the world - is given to dramatic swings. Its legislative system is often defined by gridlock on matters large and small. The use of the initiative, one of the tools of "direct democracy", has become commonplace. Over the years, California has had more than its share of political turmoil. But for pure melodrama, nothing matches the 2003 campaign to recall the state's sitting governor, Gray Davis. Recall! relates the latest and most dramatic chapter in the political history of the Golden State. The authors are recognized experts on California politics and regular local television political analysts. They provide fascinating coverage of the events leading up to Davis's replacement by bodybuilder-turned actor-turned politician Arnold Schwarzenegger; describe the large and colorful cast of characters involved in the special election; and demonstrate how California's one-of-a-kind mix of political, economic, and social circumstances made it all possible.

Recent Advancement in White Biotechnology Through Fungi: Volume 1: Diversity and Enzymes Perspectives (Fungal Biology)
by Ajar Nath Yadav Shashank Mishra Sangram Singh Arti GuptaWhite biotechnology, or industrial biotechnology as it is also known, refers to the use of living cells and/or their enzymes to create industrial products that are more easily degradable, require less energy, create less waste during production and sometimes perform better than products created using traditional chemical processes.Over the last decade considerable progress has been made in white biotechnology research, and further major scientific and technological breakthroughs are expected in the future. Fungi are ubiquitous in nature and have been sorted out from different habitats, including extreme environments (high temperature, low temperature, salinity and pH), and may be associated with plants (epiphytic, endophytic and rhizospheric).The fungal strains are beneficial as well as harmful for human beings. The beneficial fungal strains may play important roles in the agricultural, industrial, and medical sectors. The fungal strains and their products (enzymes, bioactive compounds, and secondary metabolites) are very useful for industry (e.g., the discovery of penicillin from Penicillium chrysogenum). This discovery was a milestone in the development of white biotechnology as the industrial production of penicillin and antibiotics using fungi moved industrial biotechnology into the modern era, transforming it into a global industrial technology. Since then, white biotechnology has steadily developed and now plays a key role in several industrial sectors, providing both high value nutraceutical and pharmaceutical products. The fungal strains and bioactive compounds also play an important role in environmental cleaning. This volume covers the latest developments and research in white biotechnology with a focus on diversity and enzymes.
Recent Advancement in White Biotechnology Through Fungi: Volume 2: Perspective for Value-Added Products and Environments (Fungal Biology)
by Ajar Nath Yadav Sangram Singh Shashank Mishra Arti GuptaWhite biotechnology is industrial biotechnology dealing with various biotech products through applications of microbes. The main application of white biotechnology is commercial production of various useful organic substances, such as acetic acid, citric acid, acetone, glycerine, etc., and antibiotics like penicillin, streptomycin, mitomycin, etc., and value added product through the use of microorganisms especially fungi and bacteria. The value-added products included bioactive compounds, secondary metabolites, pigments and industrially important enzymes for potential applications in agriculture, pharmaceuticals, medicine and allied sectors for human welfare. In the 21st century, techniques were developed to harness fungi to protect human health (through antibiotics, antimicrobial, immunosuppressive agents, value-added products etc.), which led to industrial scale production of enzymes, alkaloids, detergents, acids, biosurfactants. The first large-scale industrial applications of modern biotechnology have been made in the areas of food and animal feed production (agricultural/green biotechnology) and pharmaceuticals (medical/red biotechnology). In contrast, the production of bio-active compounds through fermentation or enzymatic conversion is known industrial or white biotechnology. The beneficial fungal strains may play important role in agriculture, industry and the medical sectors. The beneficial fungi play a significance role in plant growth promotion, and soil fertility using both, direct (solubilization of phosphorus, potassium and zinc; production of indole acetic acid, gibberellic acid, cytokinin and siderophores) and indirect (production of hydrolytic enzymes, siderophores, ammonia, hydrogen cyanides and antibiotics) mechanisms of plant growth promotion for sustainable agriculture. The fungal strains and their products (enzymes, bio-active compounds and secondary metabolites) are very useful for industry. The discovery of antibiotics is a milestone in the development of white biotechnology. Since then, white biotechnology has steadily developed and now plays a key role in several industrial sectors, providing both high valued nutraceuticals and pharmaceutical products.
