Download or read book Écosystèmes forestiers des Caraïbes written by and published by KARTHALA Editions. This book was released on 2009 with total page 826 pages. Available in PDF, EPUB and Kindle. Book excerpt: Grâce à la grande diversité des organisations biologiques, notamment des bio-systèmes forestiers, la Caraïbe fait partie des 34 Hotspots actuels de la biosphère. C'est une aire géographique extraordinaire pour l'évolution du vivant, car les différents canevas régionaux - géomorphologiques, pédologiques, climatiques - associés aux îles, à la bordure continentale et à l'isthme ont induit une pluralité de biotopes. Ce qui a conditionné autant de communautés floristiques et faunistiques, de physionomies et de paysages. Tous les écosystèmes de l'espace intertropical y sont représentés. Néanmoins, les sociétés successives depuis la découverte des Amériques, tout en utilisant les ressources offertes par les écosystèmes du Nouveau Monde, les ont architecturés et les paysages notamment végétaux du présent sont des témoins pertinents de ce processus. L'érosion biologique régulière, consubstantielle à la croissance des productions humaines, reste, encore aujourd'hui, un danger pour le développement de ces territoires : bien des aspects floristiques et faunistiques sont encore inconnus. En quelque sorte, dans cette partie du monde la recherche est " insaturée ". Le colloque de décembre 2005 sur les " Écosystèmes forestiers des Caraïbes " organisé par le Conseil Général de la Martinique et piloté scientifiquement par l'Université des Antilles et de la Guyane (sous la direction de Philippe Joseph), a mis en relief la problématique de la biodiversité des terres qui enserrent la mer des Caraïbes. Et, plus largement, celle de la planète tout entière confrontée au changement climatique et à ses conséquences à long terme sur les milieux anthropisés, singulièrement les modifications des frontières écosystémiques et les espèces envahissantes. La mise en perspective des données obtenues par les chercheurs de champs disciplinaires variés, qui relèvent des sciences exactes, humaines, juridiques et économiques, a fourni une somme importante de connaissances et de méthodes. Celles-ci permettent d'éclairer la décision publique, en particulier pour améliorer les outils de gestion et de planification des forêts caribéennes. Par cette initiative, le Conseil Général de la Martinique, à l'instar de son président, a indiqué la voie qui devrait permettre, à long terme, une conservation et une valorisation de toutes les diversités biologiques. Au regard des modifications climatiques futures, en effet, le potentiel évolutif des bio-systèmes doit être, par tous les moyens, préservé.

Available in PDF, EPUB and Kindle. Book excerpt: The most complete, nonpartisan source of information on this hot agronomic topic available today, this book brings together a diverse group of papers and data to resolve the debate between sedimentologists and soil scientists and agronomists over whether the effects of soil erosion on carbon and atmospheric CO2 is beneficial or destructive. Divided into four sections, it offers data on how soil erosion affects soil, water, and air quality. Topics include mineralization rate, inundation, sediment deposition, and global warming potential, as well as carbon dioxide, methane, and nitrous oxide emissions, and the implications of soil erosion on the global carbon cycle and carbon budget.

Download or read book Sustainable Agriculture Reviews 14 written by Harry Ozier-Lafontaine and published by Springer. This book was released on 2014-09-03 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainable agriculture is a rapidly growing field aiming at producing food and energy in a sustainable way for humans and their children. Sustainable agriculture is a discipline that addresses current issues such as climate change, increasing food and fuel prices, poor-nation starvation, rich-nation obesity, water pollution, soil erosion, fertility loss, pest control, and biodiversity depletion. Novel, environmentally-friendly solutions are proposed based on integrated knowledge from sciences as diverse as agronomy, soil science, molecular biology, chemistry, toxicology, ecology, economy, and social sciences. Indeed, sustainable agriculture decipher mechanisms of processes that occur from the molecular level to the farming system to the global level at time scales ranging from seconds to centuries. For that, scientists use the system approach that involves studying components and interactions of a whole system to address scientific, economic and social issues. In that respect, sustainable agriculture is not a classical, narrow science. Instead of solving problems using the classical painkiller approach that treats only negative impacts, sustainable agriculture treats problem sources. Because most actual society issues are now intertwined, global, and fast-developing, sustainable agriculture will bring solutions to build a safer world.

Download or read book MEGA-CRISES written by Ira Helsloot and published by Charles C Thomas Publisher. This book was released on 2012-08-01 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: We live in turbulent times with continents and nations facing ever-heightening risks such as natural disasters, intense and protracted conflicts, terrorism, corporate crises, cyber threats to infrastructures and mega-events. We are witnessing the rise of mega-crises and a new class of adversity with many unknowns. The prospect of mega-crises presents professionals and students in the field of crisis management with four major tasks. First, they should engage in “deep thinking” about the causes of the increasing occurrence of mega-crises. Second, they should identify and work through the dominant trends which complicate contemporary crisis management. Third, they should upgrade institutional crisis management capacity. Fourth, they should improve societal resilience since no institutional complex can mitigate or manage these mega-crisis on its own. This book is divided into four primary parts, each of which looks at one facet of mega-crises. Part I focuses on the concept of a mega-crisis and mega-crisis management; Part II examines crisis management of mega-natural disasters; Part III evaluates crisis management of man-made mega-crises; and Part IV identifies mega-threats and vulnerabilities. Additional major topics include Hurricane Katrina; Hurricane Gustav; the London Bombings; the Mumbai Terrorist Attacks of July 7, 2005; corporate meltdowns; the subprime crisis; the Olympic Games; electricity grids; global climate change; the Dutch Delta; risks to food security; and mega-crises and the Internet. This comprehensive text will provide practitioners and academics with the results of an across-the-board research effort in the prospects, nature, characteristics, and the effects of mega-crises.

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.
