Eine wichtige Teilma\u00dfnahme ist der Schutz vor Bodenerosion, insbesondere in H\u00fcgelgebieten mit viel landwirtschaftlicher Nutzung. Der Grund hierf\u00fcr liegt darin, dass es sich bei den gef\u00e4hrdeten D\u00f6rfern vor allem um D\u00f6rfer handelt, die in von landwirtschaftlich genutzten H\u00e4ngen umgebenen T\u00e4lern liegen, deren Stabilit\u00e4t durch ein dichtes Wurzelwerk nicht ausreichend gew\u00e4hrleistet ist.<\/p>\n<p>Es ist seit langem bekannt, dass sogenannte \u201eHangtrennungszonen\u201c ein sehr wirksames Mittel zur Bek\u00e4mpfung der Bodenerosion sind. Diese Fl\u00e4chen sind von der normalen landwirtschaftlichen Nutzung ausgeschlossen und dienen der R\u00fcckhaltung von Regenwasser. Allerdings mussten Landwirte, die solche Zonen umsetzen, bislang Einbu\u00dfen hinnehmen, da ihnen diese Zonen keine Ernte einbringen. Werden Hangtrennfl\u00e4chen jedoch mit photovoltaischen Erosionsschutzsystemen ausgestattet, ist dies eine Win-Win-Situation.<\/p>\n<p>Dieses \u201eFlower Power\u201c genannte System wurde 2020 von der Ewind GmbH entwickelt und als internationales Patent angemeldet. Einzelne Reihen von Solarmodulen gliedern den Hang und halten dank pfahlverst\u00e4rkter D\u00e4mme zus\u00e4tzlich bis zu 1 Million Liter Regenwasser pro Hektar zur\u00fcck. Zudem erzeugen Solarmodule Strom, der den Landwirten eine Einnahmequelle auf der Fl\u00e4che garantiert. Bl\u00fchstreifen zwischen den Modulen f\u00f6rdern zudem die Artenvielfalt und den Insektenschutz. Aber auch auf stark beschatteten Fl\u00e4chen, die mit Solarmodulen bedeckt sind, k\u00f6nnen Nutzpflanzen wie zum Beispiel Heidelbeeren angebaut werden. In Versuchsparzellen konnten selbst bei neunzig Prozent Schatten noch sehr gute Ertr\u00e4ge erzielt werden.<\/p>\n<p>Das System verhindert nicht nur direkte Sch\u00e4den durch Erosion; Durch die Ansammlung und langsame Abgabe des Wassers in den darunterliegenden Hang verbessert sich zudem die Bodenfeuchtigkeit deutlich.<\/p>\n<p>Quelle:<\/p>\n<p>pv-magazine, article by Volker Korrmann, Ewind Betreiber- und Vertriebs- GmbH from 07\/22\/2021: \u00a0<a href=\"https:\/\/www.pv-magazine.de\/2021\/07\/22\/wirtschaftlicher-erosionsschutz-mit-photovoltaik-anlagen\/\">https:\/\/www.pv-magazine.de\/2021\/07\/22\/wirtschaftlicher-erosionsschutz-mit-photovoltaik-anlagen\/<\/a>\u00a0(last access on 10\/05\/2021 at 2 p.m.)<\/p>\n<p><a href=\"https:\/\/www.lfl.bayern.de\/mam\/cms07\/publikationen\/daten\/schriftenreihe\/starkregen-bodenerosion_sturzfluten_lfl-schriftenreihe.pdf\">https:\/\/www.lfl.bayern.de\/mam\/cms07\/publikationen\/daten\/schriftenreihe\/starkregen-bodenerosion_sturzfluten_lfl-schriftenreihe.pdf<\/a>\u00a0(last access on 10\/05\/2021 at 1.30 p.m.)<\/p>","protected":false},"excerpt":{"rendered":"<p>In the aftermath of the flood disaster in parts of Germany, various measures are being discussed to better protect the population from heavy rainfall events in the future.
