Wieviel Natur verlieren wir durch höhere Erträge?

UFZ-Studie zeigt Zusammenhang zwischen Ertragsteigerungen und Artenvielfalt

(PresseBox) (Leipzig, )
Um den Ertrag bewirtschafteter Nutzflächen zu steigern, wird die Landnutzung intensiviert. In welchem Maß der Ertrag dabei zunimmt, und wie hoch gleichzeitig der Verlust der biologischen Vielfalt ausfällt, darüber ist bislang kaum etwas bekannt. Ein internationales Team von Wissenschaftlerinnen und Wissenschaftlern hat nun unter Leitung des UFZ Daten weltweiter Forschungsarbeiten ausgewertet, in denen sowohl Ertrag als auch Biodiversität vor und nach Intensivierungsmaßnahmen untersucht wurden. Die Resultate dieser Meta-Analyse sind jetzt im Fachmagazin Global Change Biology veröffentlicht.

Rund 80 Prozent der Landflächen in Europa sind besiedelt und werden land- und forstwirtschaftlich genutzt.
