Darwinian Agriculture

by R. Ford Denison, Darwinian Agriculture Books available in PDF, EPUB, Mobi Format. Download Darwinian Agriculture books, As human populations grow and resources are depleted, agriculture will need to use land, water, and other resources more efficiently and without sacrificing long-term sustainability. Darwinian Agriculture presents an entirely new approach to these challenges, one that draws on the principles of evolution and natural selection. R. Ford Denison shows how both biotechnology and traditional plant breeding can use Darwinian insights to identify promising routes for crop genetic improvement and avoid costly dead ends. Denison explains why plant traits that have been genetically optimized by individual selection--such as photosynthesis and drought tolerance--are bad candidates for genetic improvement. Traits like plant height and leaf angle, which determine the collective performance of plant communities, offer more room for improvement. Agriculturalists can also benefit from more sophisticated comparisons among natural communities and from the study of wild species in the landscapes where they evolved. Darwinian Agriculture reveals why it is sometimes better to slow or even reverse evolutionary trends when they are inconsistent with our present goals, and how we can glean new ideas from natural selection's marvelous innovations in wild species.

Principles Of Agronomy For Sustainable Agriculture

by Francisco J. Villalobos, Principles Of Agronomy For Sustainable Agriculture Books available in PDF, EPUB, Mobi Format. Download Principles Of Agronomy For Sustainable Agriculture books, This textbook explains the various aspects of sustainable agricultures to undergraduate and graduate students. The book first quantifies the components of the crop energy balance, i.e. the partitioning of net radiation, and their effect on the thermal environment of the canopy. The soil water balance and the quantification of its main component (evapotranspiration) are studied to determine the availability of water to rain fed crops and to calculate crop water requirements. Then it sets the limitations of crop production in relation to crop phenology, radiation interception and resource availability (e.g. nutrients). With that in mind the different agricultural techniques (sowing, tillage, irrigation, fertilization, harvest, application of pesticides, etc.) are analyzed with special emphasis in quantifying the inputs (sowing rates, fertilizer amounts, irrigation schedules, tillage plans) required for a given target yield under specific environmental conditions (soil & climate). For all techniques strategies are provided for improving the ratio productivity/resource use while ensuring sustainability. The book comes with online practical focusing on the key aspects of management in a crop rotation (collecting weather data, calculating productivity, sowing rates, irrigation programs, fertilizers rates etc).

The Solar Revolution

by Steve McKevitt, The Solar Revolution Books available in PDF, EPUB, Mobi Format. Download The Solar Revolution books, It’s an astonishing fact that capturing all the energy in just one hour’s worth of sunlight would enable us to meet the planet’s food and energy needs for an entire year. The Solar Revolution tells the story of how scientists are working to reconnect us to the ‘solar economy’, harnessing the power of the sun to provide sustainable food and energy for a global population of 10 billion people: an achievement that would end our dependence on ‘fossilised sunshine’ in the form of coal, oil and gas and remake our connection with the soil that grows our food. Steve McKevitt and Tony Ryan describe the human race’s complex relationship with the sun and take us back through history to see how our world became the place it is today – chemically, geologically, ecologically, climatically and economically – before moving on to the cutting-edge science and technology that will enable us to live happily in a sustainable future.

The Tao Of Vegetable Gardening

by Carol Deppe, The Tao Of Vegetable Gardening Books available in PDF, EPUB, Mobi Format. Download The Tao Of Vegetable Gardening books, The Tao of Vegetable Gardening explores the practical methods as well as the deeper essence of gardening. In her latest book, groundbreaking garden writer Carol Deppe (The Resilient Gardener, Breed Your Own Vegetable Varieties) focuses on some of the most popular home garden vegetables—tomatoes, green beans, peas, and leafy greens—and through them illustrates the key principles and practices that gardeners need to know to successfully plant and grow just about any food crop. Deppe’s work has long been inspired and informed by the philosophy and wisdom of Tao Te Ching, the 2,500-year-old work attributed to Chinese sage Lao Tzu and the most translated book in the world after the Bible. The Tao of Vegetable Gardening is organized into chapters that echo fundamental Taoist concepts: Balance, Flexibility, Honoring the Essential Nature (your own and that of your plants), Effortless Effort, Non-Doing, and even Non-Knowing. Yet the book also offers a wealth of specific and valuable garden advice on topics as diverse as: • The Eat-All Greens Garden, a labor- and space-efficient way to provide all the greens a family can eat, freeze, and dry—all on a tiny piece of land suitable for small-scale and urban gardeners. • The growing problem of late blight and the future of heirloom tomatoes—and what gardeners can do to avoid problems, and even create new resistant varieties. • Establishing a Do-It-Yourself Seed Bank, including information on preparing seeds for long-term storage and how to “dehybridize” hybrids. • Twenty-four good places to not plant a tree, and thirty-seven good reasons for not planting various vegetables. Designed for gardeners of all levels, from beginners to experienced growers, The Tao of Vegetable Gardening provides a unique frame of reference: a window to the world of nature, in the garden and in ourselves.

Darwinian Archaeologies

by Herbert D.G. Maschner, Darwinian Archaeologies Books available in PDF, EPUB, Mobi Format. Download Darwinian Archaeologies books, Just over 20 years ago the publication of two books indicated the reemergence of Darwinian ideas on the public stage. E. O. Wilson's Sociobiology: The New Synthesis and Richard Dawkins' The Selfish Gene, spelt out and developed the implications of ideas that had been quietly revolutionizing biology for some time. Most controversial of all, needless to say, was the suggestion that such ideas had implications for human behavior in general and social behavior in particular. Nowhere was the outcry greater than in the field of anthropology, for anthropologists saw themselves as the witnesses and defenders of human di versity and plasticity in the face of what they regarded as a biological determin ism supporting a right-wing racist and sexist political agenda. Indeed, how could a discipline inheriting the social and cultural determinisms of Boas, Whorf, and Durkheim do anything else? Life for those who ventured to chal lenge this orthodoxy was not always easy. In the mid-l990s such views are still widely held and these two strands of anthropology have tended to go their own way, happily not talking to one another. Nevertheless, in the intervening years Darwinian ideas have gradually begun to encroach on the cultural landscape in variety of ways, and topics that had not been linked together since the mid-19th century have once again come to be seen as connected. Modern genetics turns out to be of great sig nificance in understanding the history of humanity.

Rethinking Agriculture

by Timothy P Denham, Rethinking Agriculture Books available in PDF, EPUB, Mobi Format. Download Rethinking Agriculture books, Although the need to study agriculture in different parts of the world on its “own terms” has long been recognized and re-affirmed, a tendency persists to evaluate agriculture across the globe using concepts, lines of evidence and methods derived from Eurasian research. However, researchers working in different regions are becoming increasingly aware of fundamental differences in the nature of, and methods employed to study, agriculture and plant exploitation practices in the past. Contributions to this volume rethink agriculture, whether in terms of existing regional chronologies, in terms of techniques employed, or in terms of the concepts that frame our interpretations. This volume highlights new archaeological and ethnoarchaeological research on early agriculture in understudied non-Eurasian regions, including Island Southeast Asia and the Pacific, the Americas and Africa, to present a more balanced view of the origins and development of agricultural practices around the globe.

Darwin S Spectre

by Michael R. Rose, Darwin S Spectre Books available in PDF, EPUB, Mobi Format. Download Darwin S Spectre books, Extending the human life-span past 120 years. The "green" revolution. Evolution and human psychology. These subjects make today's newspaper headlines. Yet much of the science underlying these topics stems from a book published nearly 140 years ago--Charles Darwin's On the Origin of Species. Far from an antique idea restricted to the nineteenth century, the theory of evolution is one of the most potent concepts in all of modern science. In Darwin's Spectre, Michael Rose provides the general reader with an introduction to the theory of evolution: its beginning with Darwin, its key concepts, and how it may affect us in the future. First comes a brief biographical sketch of Darwin. Next, Rose gives a primer on the three most important concepts in evolutionary theory--variation, selection, and adaptation. With a firm grasp of these concepts, the reader is ready to look at modern applications of evolutionary theory. Discussing agriculture, Rose shows how even before Darwin farmers and ranchers unknowingly experimented with evolution. Medical research, however, has ignored Darwin's lessons until recently, with potentially grave consequences. Finally, evolution supplies important new vantage points on human nature. If humans weren't created by deities, then our nature may be determined more by evolution than we have understood. Or it may not be. In this question, as in many others, the Darwinian perspective is one of the most important for understanding human affairs in the modern world. Darwin's Spectre explains how evolutionary biology has been used to support both valuable applied research, particularly in agriculture, and truly frightening objectives, such as Nazi eugenics. Darwin's legacy has been a comfort and a scourge. But it has never been irrelevant.
