Book Description
An interdisciplinary and quantitative account of human claims on the biosphere's stores of living matter, from prehistoric hunting to modern energy production. The biosphere—the Earth's thin layer of life—dates from nearly four billion years ago, when the first simple organisms appeared. Many species have exerted enormous influence on the biosphere's character and productivity, but none has transformed the Earth in so many ways and on such a scale as Homo sapiens. In Harvesting the Biosphere, Vaclav Smil offers an interdisciplinary and quantitative account of human claims on the biosphere's stores of living matter, from prehistory to the present day. Smil examines all harvests—from prehistoric man's hunting of megafauna to modern crop production—and all uses of harvested biomass, including energy, food, and raw materials. Without harvesting of the biomass, Smil points out, there would be no story of human evolution and advancing civilization; but at the same time, the increasing extent and intensity of present-day biomass harvests are changing the very foundations of civilization's well-being. In his detailed and comprehensive account, Smil presents the best possible quantifications of past and current global losses in order to assess the evolution and extent of biomass harvests. Drawing on the latest work in disciplines ranging from anthropology to environmental science, Smil offers a valuable long-term, planet-wide perspective on human-caused environmental change.

Book Description
How did life begin on the early Earth? We know that life today is driven by the universal laws of chemistry and physics. By applying these laws over the past ?fty years, en- mous progress has been made in understanding the molecular mechanisms that are the foundations of the living state. For instance, just a decade ago, the ?rst human genome was published, all three billion base pairs. Using X-ray diffraction data from crystals, we can see how an enzyme molecule or a photosynthetic reaction center steps through its catalytic function. We can even visualize a ribosome, central to all life, translate - netic information into a protein. And we are just beginning to understand how molecular interactions regulate thousands of simultaneous reactions that continuously occur even in the simplest forms of life. New words have appeared that give a sense of this wealth of knowledge: The genome, the proteome, the metabolome, the interactome. But we can’t be too smug. We must avoid the mistake of the physicist who, as the twentieth century began, stated con?dently that we knew all there was to know about physics, that science just needed to clean up a few dusty corners. Then came relativity, quantum theory, the Big Bang, and now dark matter, dark energy and string theory. Similarly in the life sciences, the more we learn, the better we understand how little we really know. There remains a vast landscape to explore, with great questions remaining.

Book Description
This book provides the first comprehensive and critical examination of the spatial assumptions underpinning transboundary protected areas in Europe, at a time of surging global enthusiasm in creating and managing such areas. It explores how the reliance on the natural science approach to space within environmental planning has led to a return of exclusionary discourses, in paradoxical contrast to the stated claims of designing 'peace parks'. The book builds a much-needed link between the critical geopolitical literature on boundaries and social approaches to nature and hybridity. Drawing the Line is theoretically informed yet grounded in substantial fieldwork from sites in France, Germany, Italy, Poland, Romania, Slovakia and the Ukraine. It uses material from the field to build and question theoretical debates, moving beyond site-specific issues to wider patterns and trends.

Book Description
The present book offers an overall up-to-date overview of the biological diversity, comprising many interesting chapters focussing on the different aspects of biodiversity. Most of the chapters include findings of investigations and observations on biodiversity, whilst a few are based on statistically and theoretically derived information. The book produced sufficient information on the occurrence and distribution of many plant and animal species or groups of organisms with environmental estimates from a wide variety of interesting terrestrial and aquatic habitats. With 18 interesting and elaborately prepared chapters, the present book would definitely be an ideal source of scientific information to the advanced students, junior researchers, scientists and a portion of the public involved in ecology and other research areas involving biodiversity studies. It will also help to the development of the growing awareness of the close linkage between the conversation of biodiversity and economic development.

Book Description
This book provides a synthesis of the past decade of research into global changes that occurred in the earth system in the past. Focus is achieved by concentrating on those changes in the Earth's past environment that best inform our evaluation of current and future global changes and their consequences for human populations. The book stands as a ten year milestone in the operation of the Past Global Changes (PAGES) Project of the International Geosphere-Biosphere Programme (IGBP). It seeks to provide a quantitative understanding of the Earth’s environment in the geologically recent past and to define the envelope of natural environmental variability against which anthropogenic impacts on the Earth System may be assessed. A set of color overhead transparencies based on the figures in the book is available free on the PAGES website (www.pages-igbp.org) for use in teaching and lecturing.

Book Description
Reinventing Critical Pedagogy offers a fresh perspective from which to read, discuss, and debate recent critical interpretations of schooling and our world at present. The authors build upon past accomplishments of critical pedagogy and critique those elements that contradict the radically democratic orientation of the field. Ultimately, they argue that critical pedagogy needs to welcome a wider representational and ideological base for the oppressed, and that it should do so in a way that makes the field more vital in the preparation for the revolutionary struggles ahead. Reinventing Critical Pedagogy takes a step in that direction because it not only takes to task OexternalO forces such as capitalism, patriarchy, and white supremacy, but also engages the manifestations of these external forces within critical pedagogy itself.

Book Description
A collection of fifteen essays exploring what folklore is, its history, and how it all connects to the world. Celebrated folklorist, Dorothy Noyes, offers an unforgettable glimpse of her craft and the many ways it matters. Folklore is the dirty linen of modernity, carrying the traces of working bodies and the worlds they live in. It is necessary but embarrassing, not easily blanched and made respectable for public view, although sometimes this display is deemed useful. The place of folklore studies among modern academic disciplines has accordingly been marginal and precarious, yet folklore studies are foundational and persistent. Long engaged with all that escapes the gaze of grand theory and grand narratives, folklorists have followed the lead of the people whose practices they study. They attend to local economies of meaning; they examine the challenge of making room for maneuver within circumstances one does not control. Incisive and wide ranging, the fifteen essays in this book chronicle the “humble theory” of both folk and folklorist as interacting perspectives on social life in the modern Western world. “Tying folklore to larger trends in Western cultural thought, leaving behind narrow concerns with genre or fossilized expressive forms, Humble Theory showcases the potential of folkloristics to contribute meaningfully to interdisciplinary conversations about culture.” —Journal of Folklore Research “Humble Theory is a big book. From a small scholarly field, it announces the most substantial, far-seeing insights into the world’s social life. By writing it, Noyes becomes the kind of public intellectual the United States needs.” —Journal of American Folklore
