Download or read book La degradaci n de los suelos por erosi n h drica m todos de estimaci n written by Javier Almorox Alonso and published by EDITUM. This book was released on 2011-01-20 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: La degradación de la tierra está ocurriendo en todo el mundo y en casi todos los ecosistemas, este proceso tiene graves consecuencias medioambientales y sobre el potencial biológico y económico de la tierra. Uno de los mecanismos más importantes de la degradación de la tierra es la erosión del suelo. El suelo es un recurso natural único, frágil, imprescindible para la vegetación, para la sostenibilidad global y la calidad de vida; sin este recurso no puede haber prosperidad ni progreso. La erosión hídrica es el eje central de desarrollo de la presente publicación la cual tiene por objeto sintetizar algunos conceptos teóricos sobre la degradación y erosión de suelos, para luego avanzar sobre los modelos de estimación de la erosión hídrica.

Book excerpt: Dryland agriculture is of more consequence now than ever because the world's dependence on food produced in dryland areas is even greater. In recognition of this, and the fact that global food supply is increasingly interconnected, this volume takes a world view of dryland production continent by continent. The initial chapters of the monograph address the principles that underlie all dryland farming, and are the basis for the following chapters that address dryland farming issues around the world.

Download or read book Soil Quality for Crop Production and Ecosystem Health written by E.G. Gregorich and published by Elsevier. This book was released on 1997-11-10 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil is a complex body that exists as many types, each with diverse properties that may vary widely across time and space as a function of many factors. This complexity makes the evaluation of soil quality much more challenging than that of water or air quality. Evaluation of soil quality now considers environmental implications as well as economic productivity, seeking to be more holistic in its approach.Thus, soil quality research draws from a wide range of disciplines, blending the approaches of biologists, physicists, chemists, ecologists, economists and agronomists, among others.This book presents a broad perspective of soil quality that includes these various perspectives and gives a strong theoretical basis for the assessment of soil quality.A short glossary provides definitions for terms used throughout the book.

Download or read book Mediterranean Oak Woodland Working Landscapes written by Pablo Campos and published by Springer Science & Business Media. This book was released on 2013-06-18 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: The oak tree was a boon companion as humans expanded their presence across much of the globe. While oak woodlands (Quercus spp.) come today in stunningly diverse forms, the stately dehesas of Spain and the dramatic oak-dominated ranchlands of California are working landscapes where cultivation and manipulation for a couple of millennia have shaped Mediterranean-type ecosystems into a profoundly modified yet productive environment that is sought-after by every manner of species. The grazing of wildlife and livestock in oak woodlands yields a remarkable plant and animal biodiversity, creating a mosaic of habitats and visually pleasing savannas. Added products unique to Spain such as Iberian pigs and cork, and in California multiple landowner benefits, include valued ecosystem services that allow owners, visitors, and conservation supporters to experience the benefits of woodland life. With its 15 chapters a decade in the making, this handsomely illustrated book covers key topics in oak woodland policy, ecology, and management in Spain and California, presenting new research results and reviewing an existing expert literature.
Download or read book Advances in Soil Science written by and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of Advances in Soil Science is to provide a forum for leading scientists to analyze and summarize the available scientific information on a subject, assessing its importance and identifying additional research needs. A wide array of subjects has been addressed by authors from many countries in the initial ten volumes of the series. The quick acceptance of the series by both authors and readers has been very gratifying and confirms our perception that a need did exist for a medium to fill the gap between the scientific journals and the comprehensive reference books. This volume is the first of the series devoted entirely to a single topic soil degradation. Future volumes will include both single-topic volumes as well as volumes containing reviews of different topics of soil science, as in the case of the first ten volumes. There are increasing concern and attention about managing natural re sources, particularly soil and water. Soil degradation is clearly one of the most pressing problems facing mankind. Although the spotlight regarding soil degradation in recent years has focused on Africa, concern about the degradation of soil and water resources is worldwide. The widespread con cern about global environmental change is also being linked to severe problems of soil degradation. Therefore, we are indeed pleased that the first volume of the series devoted to a single topic addresses such an impor tant issue. The current volume is also the first of the series involving a guest editor.
Download or read book Mahatma Gandhi written by Dennis Dalton and published by Columbia University Press. This book was released on 2012-02-21 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dennis Dalton's classic account of Gandhi's political and intellectual development focuses on the leader's two signal triumphs: the civil disobedience movement (or salt satyagraha) of 1930 and the Calcutta fast of 1947. Dalton clearly demonstrates how Gandhi's lifelong career in national politics gave him the opportunity to develop and refine his ideals. He then concludes with a comparison of Gandhi's methods and the strategies of Martin Luther King Jr. and Malcolm X, drawing a fascinating juxtaposition that enriches the biography of all three figures and asserts Gandhi's relevance to the study of race and political leadership in America. Dalton situates Gandhi within the "clash of civilizations" debate, identifying the implications of his work on continuing nonviolent protests. He also extensively reviews Gandhian studies and adds a detailed chronology of events in Gandhi's life.
