Short description

The subproject investigates the influence of the microclimate on the risk of infestation with pathogens. The forecast models used to date do not explicitly take the influence of stand and plant architecture on pathogen establishment into account. How much the stand heats up or how quickly it dries off again after a rainfall, however, depends largely on local aerodynamic properties (displacement height, roughness length, etc.). These are in turn the result of factors such as sowing density, sowing geometry, leaf area, leaf width, leaf inclination and plant height variability. These influencing factors are mapped in 3D simulations on the basis of the system tests with special consideration of equal-distance sowing. This enables better prognostic modeling of pathogen infestation of crop stands.

DFG-FOR 1695: Agricultural Landscapes under Global Climate Change – Processes and Feedbacks on a Regional Scale

Beschreibung

Aufbauend auf dem DFG-Verbundprojekt PAK 346 (2008-2011) untersucht die DFG-Forschergruppe 1695 seit 2012 in zehn Teilprojekten die Folgen des globalen Klimawandels für die Struktur und die Funktionen von Agrarlandschaften auf regionaler Skala. Gemeinsames Ziel der Arbeitsgruppen aus Hohenheim, München und Gießen ist es, durch eine Kombination aus integrierter Modellierung, intensiven Feldmessungen und kontrollierten Experimenten zu einem verbesserten Prozessverständnis und einer besseren Kenntnis der Wechselwirkungen zwischen Landoberfläche und Atmosphäre beizutragen, um so Projektionen der Landschaftsentwicklung und möglicher Anpassungsstrategien bis 2030 ableiten zu können. Dazu werden hochaufgelöste regionale Klima-, Landnutzungs- und Pflanzenwachstumsmodelle mit sozio-ökonomischen Modellen gekoppelt und so ein neuartiges Landsystemmodell entwickelt. Mit speziellen Messgeräten und Fernerkundungsverfahren werden in den zwei Modellregionen Kraichgau und Mittlere Schwäbische Alb Daten zu Energie- und Stoffflüssen zwischen dem Boden-Pflanze-System und der Atmosphäre erhoben. In Klimakammern werden künftige CO2- und Klimabedingungen simuliert, um die Auswirkungen auf den Ertrag von Kulturpflanzen und die Qualität der erzeugten Nahrungsmittel zu untersuchen. Die in Feld- und Klimakammeruntersuchungen sowie in Betriebsbefragungen in den Modellregionen gewonnenen Daten dienen wiederum zur Verbesserung von Modellkomponenten und zur Validierung des neuen Landsystemmodells.

Nach einer positiven Begutachtung durch die DFG beginnt im Februar 2015 die zweite Phase der Projektförderung, in der die Forschergruppe 8 Teilprojekte hat. Die zweite Phase endet im September 2018.

Beschreibung

Gekoppelte Atmosphären-Landoberflächen-Modelle sind wichtige Werkzeuge, um die Auswirkungen des Klimawandels auf der regionalen Skala abzuschätzen. Die Qualität regionaler Klimasimulationen hängt wesentlich von einer guten Beschreibung der Landoberflächen­austauschprozesse ab. Hier spielen die Wechselwirkungen zwischen Böden, Pflanzen und der Atmosphäre eine Schlüsselrolle. In der ersten Phase haben wir das Pflanzenwachstumsmodell GECROS mit dem Landoberflächenmodell NOAHMP gekoppelt. In der zweiten Phase werden wir die Leistungsfähigkeit und Robustheit von NOAHMP-GECROS im Hinblick darauf testen, wie gut Bodenwasserhaushalt, Pflanzenwachstum und Landoberflächenaustausch vom Modell abgebildet werden. Die Überprüfung und nötigenfalls Weiterentwicklung wird anhand der Langzeitdaten von unseren Eddy-Kovarianz-Stationen und regionalen Bodenwassermessnetzen erfolgen. Über das Atmosphären-Landoberflächen-Pflanzenwachstums-Modell ALCM (NOAHMP-GECROS gekoppelt mit WRF) ist NOAHMP-GECROS ein wesentlicher Bestandteil des zu entwickelnden Integrierten Landsystem-Modellsystems (ILMS). In enger Zusammenarbeit mit den anderen Projekten der Forschergruppe werden wir mit ILMS Rückkopplungen in Landsystemen (Kraichgau und Schwäbische Alb) unter dem Klimawandel untersuchen. Innerhalb dieser Zusammenarbeit werden wir unter anderem klären, bis zu welchem Detail Prozesse im Bereich Boden-Pflanze abgebildet werden müssen, um Landschaftsfunktionen wie Pflan­zen­produktion und Wasser­haus­halt ausreichend genau zu simulieren.
