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.

Background and objectives
Food security is highly sensitive to climate risks in the Eastern African region. Food production, access to markets, and income from agricultural activities are connected inseparably with climate-related events and food security crises. The German-Ethiopian SDG-Graduate School entitled ‘Climate change effects on food security’ (CLIFOOD) aims at empowering young academics of HEIs on the African continent focusing on SDGs: No poverty, Zero hunger, Good health and well-being, Quality education, Climate action, Life on land, Partnerships for the goals.  Main objective of CLIFOOD is the education of African students at the (post) doctorate level to address the threats of climate change to food security in the Eastern African region. Furthermore, CLIFOOD strengthens bilateral partnerships between higher education institutions in Germany and Ethiopia, supports relevant, high-quality educational offerings of structured study courses on research subjects, achieves greatest possible multidisciplinary research, qualifies specialized experts and lecturers at doctorate and postdoc level, and contributes towards the joint development of innovative solutions to higher education and SDG topics. 

Research
Agriculture is the backbone of the Ethiopian economy, but climate change strongly affects food security in Sub-Saharan Africa. Ethiopia is facing severe droughts having impacts on the lives and livelihoods of farmers. Demand-driven research on climate change and food security will be conducted and improved within CLIFOOD with special reference to the Agenda 2030 and its SDGs. Interdisciplinary research on adaptation strategies for agriculture is conducted with respect to weed control, livestock production, food and feed crops, soil health, grain quality, farming households, human nutrition as well as seasonal weather forecasts.

Qualification program
CLIFOOD offers a unique interdisciplinary qualification program for PhD students and Postdocs. According to the research areas, it conveys knowledge and methods from a wide range of disciplines like soil science, physics, meteorology, (agro)ecology, crop science, livestock science, agricultural economics, and nutritional and food sciences.

German-Ethiopian SDG Graduate School CLIFOOD – Subproject: Reducing uncertainty in predictions of climate change impacts on agricultural crop production in Ethiopia

Status: laufend

Projektbeginn: 01.09.2016

Beschreibung

Crop models are the most common tools for assessing the threat of climate change to local and re­gional crop productivity. However, numerous studies have shown that models used to predict crop yields are highly uncertain when predicting how crops respond to changes in temperature, annual precipitation amounts and distribution, and increasing carbon dioxide concentrations. It was also shown that simulations differ across crop models and that a significant proportion of the uncertainty in climate change impact projections is due to differences in the structure of these models. Hence, applications of multi-model ensembles have been suggested to reduce uncertainty in simulation of crop response to future climate.

The aim of this project is to reduce uncertainty in predictions of climate change impacts on productivity of wheat, maize and sorghum in Ethiopia. The agro-ecosystem simulation tool box Expert-N is used to setup a multi-model ensem­ble composed of four different crop growth models combined with different water regime and nitrogen turnover models. The single ensemble members are run for different locations in Ethiopia taking into account the country-specific management strategies and climate inputs. Simulation results are tested against recent and historic yield data. Uncertainties in model predictions due to the dif­ferent model structures are quantified. Bayesian techniques are applied to calculate model weights accounting for the predictive power of each model combination. Only models with relevant predictive power (relevant weights) will finally be used for predicting crop productivity in Ethiopia during the next 20-30 years resulting in more reliable estimations of future yields, which may aid developing practicable mitigation strategies.

This subproject is part of the CLIFOOD project which is part of the Food Security Center.
