Description

Background
The UN Decade of Water for Life has raised awareness of both the social and environmental importance of water. Water scarcity, access to sanitation and health, water and women, capacity building, financing, assessment, integrated water resources management, transboundary issues, environment and biodiversity, disaster risk reduction, food and agriculture, water pollution and energy production are the issues that are discussed and addressed worldwide. Many problems in this field arise from conflicts of use. E.g. agricultural use (e.g. rice cultivation) versus urban use (drinking water and sanitation), water for energy - energy for water, or biosphere protection and agriculture. Conflicts over water always involve multiple social groups and require multiple approaches to resolution. Therefore, integrative solution strategies have to be developed, which adequately consider the different demands and necessities and enable a sustainable use of the resource water.

Objective
With this research training group, the Anton & Petra Ehrman Foundation and the University of Hohenheim aim to train outstanding young scientists, to promote internationally recognized research with relevance, and to achieve sustainable success in the development of integrative solution strategies for water use conflicts. The focus is on the qualification of outstandingly qualified, high-performing applicants within the framework of the thematic focus and a structured qualification program.

Structure of the Graduate College
The Graduate College is designed for an average number of 8 fellows over twelve years. Research topics for the fellows are proposed by Hohenheim professors and selected in an internal procedure. The selection criteria are international relevance of the topic, integration of the fellow in existing research projects to promote synergies, quality of the research network, and the career potential for the fellow. The topics are advertised internationally and the suitability of the applicants is evaluated by an independent panel. Fellowships are awarded for an initial period of two years and are extended for a further year following a positive interim evaluation. Research projects are provided with a limited budget upon justified application, which is intended to ensure the feasibility of the research. Doctoral candidates are expected to publish the results of their research in international journals as stipulated in the doctoral regulations of the University of Hohenheim for cumulative doctorates.

Qualification in the Graduate College
The Research Training Group is brought up to the strength of 8 fellows in the course of the first three years and then maintained at this level. This enables an intensive exchange between experienced and inexperienced doctoral students within the framework of modules on scientific work (methodological competence) as well as on social and personal competence, in which interdisciplinary teamwork and leadership qualities are the main focus. In addition, the fellows will participate in subject-related special courses, which are selected individually with the supervisors, as well as in interdisciplinary summer schools, workshops and conferences on the core topics of the Research Training Group. Through this mixture of qualifying teaching content, the young scientists are intensively prepared for the complex job market of "science".

Quality assurance

In addition to the tough selection criteria for both topics and applicants, fellows will report regularly on the progress of their work at a World Water Seminar. An interim evaluation after 18 months in the graduate program, with an evaluative statement from the supervisor, will determine whether the fellowship and research will continue. A public colloquium is held annually on World Water Day (March 22), at which, in addition to current developments in the subject area of the Graduate College, the fellows will report to the sponsor on their work and its progress. The Graduate Collegeis led scientifically by a professor of the University of Hohenheim and administratively by an experienced post doc.

The aim of the project is to analyze the potential added value of agroforestry systems in Germany compared to single crop cultivation through simulations with the plant growth/agroforestry simulation software XN (Expert-N), especially with regard to ecosystem services such as crop yield, water and air pollution control, and carbon sequestration. After calibration of the model at SIGNAL's experimental sites, scenario simulations will provide answers to the question of how the potential benefits of the respective agroforestry systems depend on the intensity of cultivation and water availability under the given site conditions. In a second step, simulations will be conducted for croplands across Germany to determine which soil and climate conditions are best suited for agroforestry systems. In the third step, the new model will be used to project into the near future the extent to which the proportions of land on which agroforestry has advantages over single-crop farming will change over the next 50 years.

Short description

The sustainable management of groundwater resources in agriculturally and urban intensively used regions requires the analysis of possible future scenarios as well as real-time planning tools. In the project, tools are developed to support water utilities and authorities in order to optimize both the operational management and the long-term planning of groundwater management. A focus is on the impacts of climate change induced changes in land management on groundwater resources in terms of groundwater recharge and seepage quality. Based on preliminary work by the applicants and the findings of the results of the current Baden-Württemberg “Water Supply Master Plan”, models are being developed for groundwater recharge, nitrogen load, groundwater levels, catchment areas of catchments and flow times, with which scenarios of climate and land use change are calculated and management strategies including prioritization of groundwater use are simulated. A data assimilation provides an always up-to-date model with web interface for short-term to seasonal planning. The results of the scenario analyses and the planning tool provide utilities and authorities for the first time with user-friendly aids for making decisions on a scientifically sound basis in an environment of increasing conflicts and extreme weather conditions. The study area includes the Upper Gaeu (karst aquifer in the Muschelkalk) and the Neckar Valley near Tübingen (gravel aquifer/Erfurt Formation), each with several supply companies. The project maps different site conditions (geology/land use), management issues and conflicts of use. After successful demonstration, the developed approach can be applied to the future model-based areal management of management of other groundwater bodies in and outside Baden-Württemberg.

Cultivar selection for sustainability and resilience (SONAR)

Short description

Insect pests in particular are benefiting from advancing climate change, as their life cycle is usually highly dependent on temperature. Relevant for sugar beet and increasingly threatening yields are mainly aphids as carriers of dangerous yellowing viruses and the reed borer as a carrier of bacterial pathogens that manifest themselves in the SBR disease (= Syndrome Basses Richesses = syndrome of low sugar content). In both cases, considerable sugar yield losses (up to 45%) are possible.

Appropriate variety selection is not only an indispensable tool of integrated pest management; it also contributes to resilience, i.e. also to safeguarding yields under changing climatic conditions, and thus also influences the competitiveness and ultimately the survival of farms and upstream and downstream regional value chains from sugar beet. In this context, it should be noted: Only when all relevant aspects are taken into account together is the choice of variety also sustainable.

The changing framework conditions in the field of arable farming strategy, the application regulation in plant protection as well as the political objectives in federal states regarding the reduction of plant protection product use (reduction targets) cannot be achieved without a modified variety strategy. The SONAR project can make a decisive contribution to this.

Short Description

In the "DeepBluSky" project, sbp sonne and the University of Hohenheim are developing a model and implementing it as simulation software to comprehensively describe APV (combined agricultural with photovoltaics, agri-PV). The simulation predicts both agricultural yield and the amount of electricity generated by photovoltaics (PV). The software can also be used to estimate the investment cost of PV, as well as calculate the cost of agricultural land management. In particular, the software takes into account the strong coupling between the PV system and the crop in terms of light, heat and water balance. Thus, an important contribution to the energy transition and to a higher resilience of agriculture with regard to climate change can be made.

The Department of Biogeophysics contributes the plant growth modelling toolbox Expert-N and investigates the effects of the changed light, heat and humidity conditions under the PV modules and its feedbacks. From this, model parameters are to be adapted to the changed environmental conditions.

TraiMErgy aims at the complex interplay between the soil microbiome and the carbon and energy flows in soil. Our central hypothesis is that the functional complexity of the soil microbiome and SOM controls matter and energy flows in soil systems. This hypothesis is tested using a novel, complex, data-driven bioenergetic SoilSystems Model: SoSyM-C.  SoSyM-C will integrate biogeochemical, thermodynamic, multi-omics, and isotopic data. The outcome of TraiMErgy will be a deeper understanding of soil organic matter turnover, coded in a mechanistic, robust and predictive biogeochemical-bioenergetic model.

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.

The aim of the project is to develop a process-based computer model that can be used to simulate both the growth of the woody plant elements and the crucial tree/field crop interactions, and to analyze the potential added value of agroforestry systems under different boundary conditions. For this purpose, both the tree and shrub components and the field crop component are explicitly spatially represented. Since the information of the trees and shrubs is available as high-resolution three-dimensional models, they can be recombined arbitrarily in agroforestry models. Thus, for the first time, the influences of complex tree rows, hedgerows and shrubs can be considered as input variables in eco- physiological process models. Shading of arable crops and below-ground competition for nutrients and water are simulated based on ray-tracing algorithms and explicit root structure models, respectively. The model development is carried out in the agricultural and forest ecosystem model package Expert-N, in which different modules are available for the simulation of water, matter and energy fluxes in the soil-plant-atmosphere system. Approaches already available in Expert-N for simulating the interaction of different plant species are to be verified with the help of exemplarily collected data (shading, soil moisture) and further adapted to the special framework conditions in the investigated AFS. This will allow, for example, the modeling of crop yields as a function of their ecophysiological properties (keyword "shade tolerance") and the structure of the tree components present in the system. The simulations will help to find suitable tree - arable crop combinations.

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.

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.

Beschreibung

Diffuse pollution of soils, surface waters, and ground-water by a multitude of anthropogenic organic and inorganic compounds is a growing global concern. Despite decades of pollutant research, serious knowledge gaps exist concerning the fate and behavior of these pollutants on the landscape scale and their impact on water quality, ecology, and human health. In eight collaborative projects the project intends to close the gap between relevant processes identified in the laboratory and mechanisms of mass transfer and metabolic trans-formations on the landscape scale.

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.

The leaching and volatilization of pesticides from Ethiopian agricultural soils pose a long-term risk to drinking water resources and public health. Several diffusive passive samplers have been developed over the years that could be used for long-term monitoring of pesticides in soils and groundwater. However, these samplers rely on the use of highly specialized sorbents and sophisticated analytical equipment (e.g., LC-MS/MS). The goal of this project is to develop an affordable, time-integrated, passive sampling method using local materials that are easily available in Ethiopia and simplified analytical techniques to quantify pesticides in agricultural soils. Time-integrated pesticide leaching losses will be studied for site-specific parameterization of models for predicting the release of contaminants from soils and the risk they pose to human health.

Description

Soil functions control ecosystem services and perils such as the emission of greenhouse gases and accumulation or leaching of pesticides. The microbial regulation of important storage, filter and buffer functions of soils is not fully understood. In the experimental part of this project we will combine stable isotope with molecular methods (metagenomics, proteomics) and develop them further to gain information about the structure of microbial communities in soil and their functions. These data will be used to simulate biological, chemical and physical processes on various scales. Complex bottom-up models, which will explicitly account for the dynamics of enzymes, microbial communities and related transformation processes, will be parameterized with molecular biological and physicochemical data. With these simulations, we want to elucidate which small-scale regulation mechanisms may be effective on plot and field scale and how much complexity is necessary to simulate soil functions. Model-based predictions will be complemented and experimentally tested on plot and field scale.

RTG 1829 “Integrated Hydrosystem Modelling” Reactive-Transport Models of Nitrogen Cycling Informed by Molecular-Biological Data

Molecular biological data can provide quantitative information about organisms related to a specific reaction. Functional genes code for enzymes responsible for a certain reaction step for example in denitrification. Their concentrations can be seen as a proxy for the abundance of organisms with that function. More and more molecular biological data are collected in the field. However, we can currently not use it in a quantitative manner in reactive transport models since the models do not simulate these quantities. In this project reactive transport models for the nitrogen cycle which can be informed by molecular biological data are developed.

SimLearn: Completing Training Data by Iteratively Learning Simulation

Machine learning methods based on existing training data have proven to be very effective in identifying patterns and implicit dependencies in complex situations with many parameters and in providing classification, prediction and decision support with the models learned. In practice, however, the large amounts of correctly labeled training data required for such approaches are often not available.

Based on actual application examples from the agricultural sector, SimLearn examines the suitability of a new approach in which existing operative knowledge codified in simulation models is combined iteratively with the increasing insights of learned models: Extensive synthetic training data sets are generated by existing simulation models. A learning system initiated on such data will then be extended and improved by empirical data collected of actual farms. This combination fills gaps in the existing database and enables improved training. The result is a learned, more powerful model of the observed reality with improved usage potentials.

SimLearn exemplary considers the operational decisions in crop production on operational and tactical level with regard to income and environmental effects. The bioeconomic modeling system MPMAS_XN of Hohenheim University (UHOH) allows initial simulations of the effects of fertilization and cultivation decisions both from a biological (plant growth) and an economic (expected revenue) point of view. This information is combined and compared with the results of cooperating experimental farms and with standard and average values from the databases of the Kuratorium für Technologie und Bauwesen in der Landwirtschaft (KTBL). Using those generated data collections, DFKI iteratively trains a suitable learning system which enables an improved prediction and assessment of alternative courses of action.

The last decade and especially the dry and hot years 2018 to 2020 have shown that the German water supply may well reach regional-temporal bottleneck situations. Since climate change projections indicate that the climatic conditions could become even more severe in the near and distant future, it is to be investigated how water supply and demand could develop in the future. In the DVGW research program "Future Water", this is being investigated by means of two intersecting research projects. One of these is WatDEMAND.

On the one hand, the project is to forecast the multi-sectoral water demand of households, industry and agriculture spatially resolved for Germany until the year 2100. On the other hand, the resulting results will be spatially and temporally intersected with changes in water supply in the sense of initial analyses in order to identify hot-spot regions that could experience increased water shortage situations in the future. In subordinate research projects, the analysis of this evaluation will be deepened and, in addition, it will be investigated for the hot-spot regions which measures, such as adaptation of the infrastructure, creation of cross-connections and increase of the resilience, can reduce the bottlenecks.
