Read e-book online Katastrophen: Triebkraft der Evolution (German Edition) PDF

By Erhard Oeser

ISBN-10: 3896787128

ISBN-13: 9783896787125

Erhard Oeser veranschaulicht anhand vieler Beispiele, dass die Evolution als eine Abfolge von Katastrophen begreifbar ist. Dies geht mit der Erkenntnis einher, dass im Vergleich zu den erdgeschichtlichen Vernichtungsakten, die zur Entstehung neuer Welten führten, jene Ereignisse, die in der Menschheitsgeschichte die Erde verwüsteten, nichts Ungewöhnliches sind. Das Entsetzen, das uns beim Anblick von Massentod und Zerstörung ergreift, muss der Einsicht weichen, dass jede Katastrophe der Beginn einer Erneuerung ist. Diese Tendenz setzt sich in gesellschaftlichen Extremereignissen wie beispielsweise Wirtschafts-Crashs oder Kriegen citadel, deren Mechanismen viel mit evolutionären Vorgängen gemein haben.Der Schauer der uns überläuft, wenn wir über das Aussterben der Dinosaurier spekulieren, scheint nach der Lektüre von Erhard Oesers neuem Buch näher zu rücken. Denn in Anbetracht von Klima-, Seuchen- und Zivilisationskatastrophen stellt sich die Frage, ob die Menschheit bereits an ihrer eigenen Ausrottung ›arbeitet‹. Wer wird uns dann evolutionär nachfolgen, die Erde bevölkern und unsere Nische besetzen?

Wasserkraftbau im Spannungsfeld Ökologie und Ökonomie - download pdf or read online

By Astrid Kaufmann

ISBN-10: 3640271041

ISBN-13: 9783640271047

Magisterarbeit aus dem Jahr 2008 im Fachbereich Umweltwissenschaften, notice: 1,00, Technische Universität Graz (Institut für Elektrizitätswirtschaft und Energieinnovation), a hundred and fifteen Quellen im Literaturverzeichnis, Sprache: Deutsch, summary: Diese Arbeit stellt die derzeitigen Herausforderungen im Bereich des Wasserkraftbaus dar. Bei der Planung und der Errichtung von Wasserkraftanlagen sind einerseits wirtschaftliche und energiepolitische Interessen zu berücksichtigen, andererseits sind Vorgaben hinsichtlich der Erhaltung der ökologischen Funktionsfähigkeit des Gewässers einzuhalten. Auch die Gesetzeslage ist in dieser Hinsicht teilweise widersprüchlich: Einerseits fordert die europäische Klimastrategie eine Erhöhung des Anteils erneuerbarer Energien an der Gesamtenergieerzeugung, wozu die Wasserkraft unumstritten einen wesentlichen Beitrag leisten kann. Auf der anderen Seite wurde allerdings durch die Wasserrahmenrichtlinie ein Verbesserungsgebot sowie ein Verschlechterungsverbot bezüglich des Gewässerzustands erteilt, used to be einem Ausbau der Wasserkraftnutzung deutlich im Wege steht.

In der vorliegenden Arbeit werden die angesprochenen Herausforderungen aufgezeigt, die tatsächlichen Umweltauswirkungen der Wasserkraftnutzung eingehend betrachtet und Maßnahmen vorgestellt, diese so gering wie möglich zu halten. Durch eine ökonomische examine der Wasserkraftnutzung kann ermittelt werden, welche monetären Belastungen ein zukünftiger Kraftwerksbetreiber durch das Setzen diverser ökologisch orientierter Maßnahmen zu erwarten hat und inwiefern sich der Anteil dieser Ausgaben an den Gesamtkosten bei Kleinwasserkraftanlagen und Großkraftwerken unterscheidet. Grundsätzlich kann davon ausgegangen werden, dass kleinere Anlagen mit größeren wirtschaftlichen Einbußen zu rechnen haben.

Der Bau von Wasserkraftanlagen führt oft zu Widerständen seitens der Bevölkerung oder Naturschutzorganisationen. Mittels vorab geplanten Krisenmanagements wird es möglich, durch geschicktes und adäquates Vorgehen bereits in der Planungsphase die Konflikte rund um den Bau von Wasserkraftanlagen möglichst gering zu halten.
