Klimawandel Und Kuste: Die Zukunft Der Unterweserregion
Eine ernsthafte Diskussion ber die Problematik des Klimawandels ist schwierig - vor allem wegen der wissenschaftlichen Unsicherheit ber Ausma und Geschwindigkeit, aber ebenso wegen der Komplexit t der Materie, die nur disziplin bergreifend erfolgversprechend bearbeitet werden kann. Dabei ist insbesondere der K stenbereich von einem Klimawandel und seinen Folgen wie dem Meeresspiegelanstieg unmittelbar betroffen, w hrend gleichzeitig die notwendigen K stenschutzma nahmen lange Vorlaufzeiten erfordern. Das vorliegende Buch soll dazu beitragen, dass ffentlichkeit und Gesellschaft in wichtigen Teilbereichen zu gesicherten Erkenntnissen ber das tats chliche Gef hrdungspotenzial des Klimawandels kommen. Die interdisziplin re Analyse von Gef hrdung und Reaktionsm glichkeiten erm glicht diskussionsf hige Aussagen f r die Zukunft.

Waldumbau: Fur Eine Zukunftsorientierte Waldwirtschaft
Das Buch untersucht die Auswirkungen von nderungen der Waldbewirtschaftung, derzeit vorwiegend von nadelbaumdominierten Reinbest nden in strukturierte Mischw lder. Innerhalb einer nachhaltigen und naturnahen Waldwirtschaft wird dieser Prozess als kologischer Waldumbau bezeichnet. Er wird aktuell von den ffentlichen Forstverwaltungen in Deutschland und Mitteleuropa forciert. Einleitend beschreiben die Autoren Ziele, M glichkeiten und Erfordernisse des kologischen Waldumbaus. Basierend auf wissenschaftlichen Untersuchungen werden die mit dem Waldumbau einhergehenden Probleme und die zu erwartenden Folgen unter kologischen, naturschutzfachlichen und betriebswirtschaftlichen Gesichtspunkten, verst ndlich f r das Fachpublikum wie auch die Praxis, beleuchtet. Schwerpunkte sind dabei Effekte des Waldumbaus auf das kosystem Wald und benachbarte kosysteme, auf Stoffhaushalt, Artenzusammensetzung und Biodiversit t, ebenso wie die konomischen Risiken, der Einfluss der Besitzverh ltnisse und die Technikfolgen.

Ackerlandschaften: Nachhaltigkeit Und Naturschutz Auf Ertragsschwachen Standorten
In weiten Gebieten Mitteleuropas ist Ackerbau auf ertragsschwachen Standorten nur mit ffentlicher F rderung kostendeckend. Diese ist f r die n here Zukunft gesichert, langfristig aber ungewiss. Eine gro fl chige Aufgabe des Ackerbaus w re aus zahlreichen Gr nden problematisch. Ausgehend von einer historischen Betrachtung untersucht dieses Buch Perspektiven eines extensiven, multifunktionellen Ackerbaus, der Naturschutz und Erholungseignung in sein Zielb ndel integriert. Anbautechnik, Fruchtfolgen sowie Wirkungen auf Bodenfruchtbarkeit, Wasserhaushalt und Artenvielfalt werden vorgestellt. Detailliert ermittelt werden sodann die gesellschaftlichen Kosten dieses Landnutzungssystems, die sich im Vergleich mit anderen als gering erweisen. Der Erholungswert wird mittels Zahlungsbereitschaftsanalysen erhoben. Die Gegen berstellung von Kosten und Nutzen, die Akzeptanz von Seiten der Landwirtschaft sowie weitere wichtige Aspekte sprechen daf r, dem extensiven Ackerbau einen Platz im Spektrum k nftiger Landnutzungen einzur umen.

Walk in the Woods: Rediscovering America on the Appalachian Trail
Back in America after twenty years in Britain, Bill Bryson decided to reacquaint himself with his native country by walking the 2,100-mile Appalachian Trail, which stretches from Georgia to Maine. The AT offers an astonishing land-scape of silent forests and sparkling lakes -- and to a writer with the comic genius of Bill Bryson, it also provides endless opportunities to witness the majestic silliness of his fellow human beings.For a start there's the gloriously out-of-shape Stephen Katz, a buddy from Iowa along for the walk. Despite Katz's overwhelming desire to find cozy restaurants, he and Bryson eventually settle into their stride, and while on the trail they meet a bizarre assortment of hilarious characters. But A Walk in the Woods is more than just a laugh-out-loud hike. Bryson's acute eye is a wise witness to this beautiful but fragile trail, and as he tells its fascinating history, he makes a moving plea for the conservation of America's last great wilderness. An adventure, a comedy, and a celebration, A Walk in the Woods is destined to become a modern classic of travel literature.

American Earth: Environmental Writing Since Thoreau
As America and the world grapple with the consequences of global environmental change, writer and activist Bill McKibben offers this unprecedented, provocative, and timely anthology, gathering the best and most significant American environmental writing from the last two centuries. Classics of the environmental imagination—the essays of Henry David Thoreau, John Muir, and John Burroughs; Aldo LeopoldÂ's A Sand County Almanac; Rachel CarsonÂ's Silent Spring—are set against the inspiring story of an emerging activist movement, as revealed by newly uncovered reports of pioneering campaigns for conservation, passages from landmark legal opinions and legislation, and searing protest speeches. Here are some of AmericaÂ's greatest and most impassioned writers, taking a turn toward nature and recognizing the fragility of our situation on earth and the urgency of the search for a sustainable way of life. Thought-provoking essays on overpopulation, consumerism, energy policy, and the nature of “nature” join ecologistsÂ' memoirs and intimate sketches of the habitats of endangered species. The anthology includes a detailed chronology of the environmental movement and American environmental history, as well as an 80-page color portfolio of illustrations.

Reclaiming the American West
There are over 200,000 abandoned mines covering hundreds of thousands of acres in the western United States. Seen from the air, they create surreal, haunting, yet somehow beautiful landscapes of mind-boggling scale. But these scarred landscapes are only temporary: by law, mining companies are required to reclaim them, and the process of renewal exposes many physical, philosophical, technological, environmental, political, regulatory, and ethical issues.Using aerial photography, maps, designs, charts, and analyses, Alan Berger provides a colorful and insightful overview of the possibilities-and dangers-of converting these altered landscapes. Reclaiming the American West covers the historical background and policy, as well as representational, technical, and design challenges presented by working with these enormous toxic sites, many of which have been converted into landscapes of extraordinary beauty. In addition, the book gives us an unprecedented vantage point above the sublime landscapes.

Charles Robert Darwin (1809-1882) has been widely recognized since his own time as one of the most influential writers in the history of Western thought.

Grass-pinks and Companion Orchids in Your Pocket: A Guide to the Native Calopogon, Bletia, Arethusa, Pogonia, Cleistes, Eulophia, Pteroglossaspis, and Gymnadeniopsis Species of the Continental United States and Canada
Native orchids are increasingly threatened by pressure from population growth and development but, nonetheless, still present a welcome surprise to observant hikers in every state and province. Compiled and illustrated by long-time orchid specialist Paul Martin Brown, these pocket guides to the twayblades, adder's-mouths, and grass-pinks and their companions form part of a series that will cover all the wild orchids of the continental United States and Canada.Brown provides general distributional information, time of flowering, and habitat requirements for each species as well as a complete list of hybrids and the many different growth and color forms that can make identifying orchids so intriguing. For the twayblades and adder's-mouths, he includes information on 20 species, 2 additional varieties, and 2 hybrids; for the grass-pinks and companions information on 16 species, 2 additional varieties, and 6 hybrids.Most twayblades and adder's-mouths are relatively small plants with tiny green flowers, but a few have richly colored blooms or particularly interesting habits that attract the native orchid enthusiast. Grass-pinks, with their showy pink to white flowers, are some of the most conspicuous wild orchids encountered in the prairies, bogs, and open wetlands of eastern North America. Most of these species are easy to identify based upon their general appearance, range, and time of flowering. Answering three simple questions - when, where, and how does it grow? - and comparing the living plant with the striking photos in the backpack - friendly laminated guide should enable both professional and amateur naturalists to achieve the satisfaction of identifying a specific orchid.
