Abstract

Sollte der Anbau transgener Kulturen nach Ablauf des Schweizer Gentech-Moratoriums liberalisiert werden, könnte dies für die Schweizer Landwirte eine Option bieten, das landwirtschaftliche Einkommen zu stabilisieren. Aufgrund des kleinstrukturierten Ag-rarraums, dem gesetzlich verankerten Schutz der gentechnikfreien Produktion und dem im Vergleich zu anderen Staaten existieren-den Unterschied in den Kosten und Preisverhältnissen ist eine Abschätzung der Wirtschaftlichkeit einer Nutzung transgener Kul-turen notwendig. Hierzu wurde ein agentenbasiertes Modell kon-struiert, welches die räumlichen Gegebenheiten einer Untersu-chungsregion im Kanton Zürich einbezieht. Unter Annahme eines hohen Schädlingsdrucks zeigen die Modellrechnungen einen wirt-schaftlichen Vorteil insbesondere für Bt-Mais. Wird ein hoher Un-krautdruck vorausgesetzt, ist der Anbau von Ht-Raps, in Kombina-tion mit einer pfluglosen Bodenbearbeitung rentabel. Zudem las-sen sich, aufgrund der räumlichen Bedingungen, starke Variatio-nen in den Koexistenzkosten feststellen, bei denen der Anteil des administrativen Aufwandes hoch ist. Durch die Nutzung transgener Kulturen ist im Modell ein potenzieller Anstieg im Betriebsein-kommen in marginaler Höhe zu erkennen.
