This book was released on 2006 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soils are affected by human activities, such as industrial, municipal and agriculture, that often result in soil degradation and loss. In order to prevent soil degradation and to rehabilitate the potentials of degraded soils, reliable soil data are the most important prerequisites for the design of appropriate land-use systems and soil management practices as well as for a better understanding of the environment. The availability of reliable information on soil morphology and other characteristics obtained through examination and description of the soil in the field is essential, and the use of a common language is of prime importance. These guidelines, based on the latest internationally accepted systems and classifications, provide a complete procedure for soil description and for collecting field data. To help beginners, some explanatory notes are included as well as keys based on simple test and observations.--Publisher's description.

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 The economics of biological invasions written by Charles Perrings, Silvana Dalmazzone, Mark Herbert Williamson and published by Edward Elgar Publishing. This book was released on 2000-08-25 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'An interesting book catering perhaps for a more specific audience. It does however provide a somewhat new view of the problems of the field of biological invasions and is worth the effort.' - Ann Sundqvist, M2 Best Books 'Once again, Charles Perrings and colleagues have broken new ground by applying economic and ecological analysis to the very real problem of biological invasions. This is path-breaking work in what promises to be a new sub-discipline within environmental economics.' - David Pearce, University College London, UK Biological invasions - the introduction of living organisms beyond their original range - are one of the main drivers of biodiversity loss. They are a major threat to human health and a source of pests and pathogens in the world's farms, forests and fisheries. The growth of international trade and travel means that more species are being introduced to more places than ever before. This book represents the first concerted effort to understand the economic causes and consequences of biological invasions. The volume discusses the theoretical and methodological issues raised by invasion, including control strategies, modelling options, and a study of the economic, institutional and policy conditions that predispose countries to biological invasions. Also included are case studies of fisheries, agricultural systems, tropical forests and protected areas affected by invasive species in locations such as the Black Sea, Australia and Africa, and an evaluation of control programmes.

Download or read book Guide de la fertilisation raisonn e written by Christian Schvartz and published by France Agricole Editions. This book was released on 2005 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'ouvrage propose aux acteurs de la filière agricole les clefs de la mise en œuvre d'une fertilisation raisonnée, appliquée aux grandes cultures et aux prairies. Après avoir rappelé, le caractère unique des lois de l'agronomie, applicables à toutes les formes de production agricole, les auteurs abordent : - les cycles biologiques fondamentaux des éléments qui contribuent à la nutrition des végétaux, - le calcul de la fertilisation, en fonction de l'offre du sol, des objectifs de production et des interactions entre les sols et les plantes, - les moyens (notamment analytiques) dont l'agriculteur dispose pour déterminer les apports en fertilisants nécessaires ainsi que les modalités de leur application, - les aspects de la fertilisation dans différents contextes environnement, territoires, extensification, économie, qualité, réglementation. La pratique de la fertilisation, longtemps dominée par les seules contraintes technico-économiques, a considérablement évolué au cours des 50 dernières années, valorisant le progrès des connaissances scientifiques, accompagnant les exigences des consommateurs et la prise en compte des contraintes environnementales. A l'heure où l'agriculture raisonnée devient un concept familier du grand public, le COMIFER a souhaité qu'un point complet et précis soit réalisé sur les moyens disponibles pour le développement d'une fertilisation compatible avec une agriculture durable, respectueuse de l'environnement. Ce guide met à la disposition du monde agricole un recueil de références actualisé.
