Download or read book The Soil Underfoot written by G. Jock Churchman and published by CRC Press. This book was released on 2014-04-21 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: The largest part of the world’s food comes from its soils, either directly from plants, or via animals fed on pastures and crops. Thus, it is necessary to maintain, and if possible, improve the quality—and hence good health—of soils, while enabling them to support the growing world population. The Soil Underfoot: Infinite Possibilities for a Finite Resource arms readers with historical wisdom from various populations around the globe, along with current ideas and approaches for the wise management of soils. It covers the value of soils and their myriad uses viewed within human and societal contexts in the past, present, and supposed futures. In addition to addressing the technical means of maintaining soils, this book presents a culturally and geographically diverse collection of historical attitudes to soils, including philosophical and ethical frameworks, which have either sustained them or led to their degradation. Section I describes major challenges associated with climate change, feeding the increasing world population, chemical pollution and soil degradation, and technology. Section II discusses various ways in which soils are, or have been, valued—including in film and contemporary art as well as in religious and spiritual philosophies, such as Abrahamic religions, Maori traditions, and in Confucianism. Section III provides stories about soil in ancient and historic cultures including the Roman Empire, Greece, India, Japan, Korea, South America, New Zealand, the United States, and France. Section IV describes soil modification technologies, such as polymer membrane barriers, and soil uses outside commercial agriculture including the importance of soils for recreation and sports grounds. The final section addresses future strategies for more effective sustainable use of soils, emphasizing the biological nature of soils and enhancing the use of "green water" retained from rainfall.

Download or read book Histoire et agronomie written by Paul Robin and published by IRD Editions. This book was released on 2007 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: Au cours des deux derniers siècles, le champ des agronomies a été traversé par de nombreuses révolutions qui ont constitué autant de ruptures importantes. Alors que ces disciplines se trouvent aujourd'hui face à l'émergence de nouveaux paradigmes comme celui du développement durable, il était important d'amener agronomes et historiens à confronter leurs savoirs pour mieux analyser les changements sociaux et techniques qui ont découlé de ces ruptures. Si pour l'historien, les ruptures s'inscrivent essentiellement dans la durée, pour l'agronome, elles répondent davantage à des questions pratiques de production et de protection des espaces naturels. Et les sciences de l'agronomie ont beaucoup à gagner en intégrant le regard des historiens à leurs propres perceptions des hommes, des concepts et des techniques. Cet ouvrage présente le résultat des réflexions croisées de quelque trente spécialistes européens de ces deux disciplines, réunis à Montpellier deux cents ans après la parution du travail fondateur de Nicolas-Théodore de Saussure (1804).

Download or read book Lake Pavin written by Télesphore Sime-Ngando and published by Springer. This book was released on 2016-10-31 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book represents the first multidisciplinary scientific work on a deep volcanic maar lake in comparison with other similar temperate lakes. The syntheses of the main characteristics of Lake Pavin are, for the first time, set in a firmer footing comparative approach, encompassing regional, national, European and international aquatic science contexts. It is a unique lake because of its permanently anoxic monimolimnion, and furthermore, because of its small surface area, its substantially low human influence, and by the fact that it does not have a river inflow. The book reflects the scientific research done on the general limnology, history, origin, volcanology and geological environment as well as on the geochemistry and biogeochemical cycles. Other chapters focus on the biology and microbial ecology whereas the sedimentology and paleolimnology are also given attention. This volume will be of special interest to researchers and advanced students, primarily in the fields of limnology, biogeochemistry, and aquatic ecology.

Download or read book Principles of Politics Applicable to All Governments written by Benjamin Constant and published by . This book was released on 2003 with total page 594 pages. Available in PDF, EPUB and Kindle. Book excerpt: Benjamin Constant (1767-1830) was born in Switzerland and became one of France's leading writers, as well as a journalist, philosopher, and politician. His colourful life included a formative stay at the University of Edinburgh; service at the court of Brunswick, Germany; election to the French Tribunate; and initial opposition and subsequent support for Napoleon, even the drafting of a constitution for the Hundred Days. Constant wrote many books, essays, and pamphlets. His deepest conviction was that reform is hugely superior to revolution, both morally and politically. While Constant's fluid, dynamic style and lofty eloquence do not always make for easy reading, his text forms a coherent whole, and in his translation Dennis O'Keeffe has focused on retaining the 'general elegance and subtle rhetoric' of the original. Sir Isaiah Berlin called Constant 'the most eloquent of all defenders of freedom and privacy' and believed to him we owe the notion of 'negative liberty', that is, what Biancamaria Fontana describes as "the protection of individual experience and choices from external interferences and constraints." To Constant it was relatively unimportant whether liberty was ultimately grounded in religion or metaphysics -- what mattered were the practical guarantees of practical freedom -- "autonomy in all those aspects of life that could cause no harm to others or to society as a whole." This translation is based on Etienne Hofmann's critical edition of Principes de politique (1980), complete with Constant's additions to the original work.
Download or read book The Archaeology of Colonialism written by Claire L. Lyons and published by Getty Publications. This book was released on 2002 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Archaeology of Colonialism demonstrates how artifacts are not only the residue of social interaction but also instrumental in shaping identities and communities. Claire Lyons and John Papadopoulos summarize the complex issues addressed by this collection of essays. Four case studies illustrate the use of archaeological artifacts to reconstruct social structures. They include ceramic objects from Mesopotamian colonists in fourth-millennium Anatolia; the Greek influence on early Iberian sculpture and language; the influence of architecture on the West African coast; and settlements across Punic Sardinia that indicate the blending of cultures. The remaining essays look at the roles myth, ritual, and religion played in forming colonial identities. In particular, they discuss the cultural middle ground established among Greeks and Etruscans; clothing as an instrument of European colonialism in nineteenth-century Oceania; sixteenth-century Andean urban planning and kinship relations; and the Dutch East India Company settlement at the Cape of Good Hope.

Download or read book Bioclimatology and Biogeography of Africa written by Henry N. Houérou and published by Springer Science & Business Media. This book was released on 2008-12-10 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: Covering an area of over 130 million km2 spanning the Mediterranean, equator and tropics, the African continent features a spectacular geographic diversity. Consequently, it is characterised by extremely variable climatic, edaphic and ecological conditions, associated with a wide range of natural vegetation and wildlife, as well as human population density, crops and livestock. In this book, Henry Le Houérou presents his bioclimatic and biogeographic classification of Africa. The extensive data provide the basis for comparisons between various African regions, and with regions on other continents such as Latin America or the Indian subcontinent. The results constitute a rational basis for national, regional and sub-regional rural development planning, and for agricultural research dealing with aspects such as plant and animal introductions, the extrapolation or interpolation of experimental or developmental findings, and ecosystems dynamics. Possible problems of applications are also examined.

Download or read book The Boundaries of Europe written by Pietro Rossi and published by Walter de Gruyter GmbH & Co KG. This book was released on 2015-04-24 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: Europe’s boundaries have mainly been shaped by cultural, religious, and political conceptions rather than by geography. This volume of bilingual essays from renowned European scholars outlines the transformation of Europe’s boundaries from the fall of the ancient world to the age of decolonization, or the end of the explicit endeavor to “Europeanize” the world.From the decline of the Roman Empire to the polycentrism of today’s world, the essays span such aspects as the confrontation of Christian Europe with Islam and the changing role of the Mediterranean from “mare nostrum” to a frontier between nations. Scandinavia, eastern Europe and the Atlantic are also analyzed as boundaries in the context of exploration, migratory movements, cultural exchanges, and war. The Boundaries of Europe, edited by Pietro Rossi, is the first installment in the ALLEA book series Discourses on Intellectual Europe, which seeks to explore the question of an intrinsic or quintessential European identity in light of the rising skepticism towards Europe as an integrated cultural and intellectual region.
