DEAR READERS, Climate change, loss of biodiversity, sustainability goals – today’s most pressing questions are providing a wide range of global challenges. For our university with its clear focus on special crops and their products as well as its commitment to a sustainable development of cultivated landscapes and urban open spaces, these challenges are raising numerous questions. How can we develop future forms of land management, especially with regard to crops such as grapes, fruits and vegetables that require intensive crop management? How to shape urban spaces and cultivated landscapes to make them ﬁ t for the challenges of climate change while also having the potential to combat it? How can we continue to supply healthy, safe and sustainably produced food for a growing population? These are a few examples of questions our scientists are tackling in research and teaching on a global and regional scale – and coming up with solutions will sure be a huge challenge! To that end, our research must be theory-based while focusing on practical applications as well. Thanks to various collaborations, we have created a strong network with renowned universities and research institutions as well as industry partners and associations in Germany and abroad. In the future, we have to increasingly tab the enormous potential that our network provides because today’s most pressing issues have reached a global dimension and can hardly be tackled by single institutions alone – irrespective of their size. Therefore, we stand together as a cross-border network to master the numerous challenges of our industries with clever minds, smart solutions, commitment and persistency. This brochure provides a short introduction to our ﬁ elds of activity and to our – partially unique – research and teaching infrastructure. As a university with a special proﬁ le and a strong focus on covering the entire value chain of special crops, we are committed to developing strategies for a sustainable future that is worth living for everyone. Learn more about our research and teaching approaches on the following pages. We hope you enjoy reading this brochure. Yours sincerely, Prof. Dr. Hans Reiner Schultz, President Hochschule Geisenheim University Prof. Dr. Annette Reineke, Vice-President of Research

My name is lacewing, or rather common green lacewing – Chrysoperla carnea. As me and my predatory larvae feed on aphids, mite eggs and other small arthropods, we are often used for biological pest control. I am a so-called benefi cial insect and was even chosen as “Insect of the Year 1999”. As a powerful biological antagonist to harmful organisms, I help to control pests and strengthen the biological balance of ecosystems. We are particularly committed to the United Nations Sustainable Development Goals – in short SDG. With our research fi ndings and the associated knowledge transfer, we seek to make a substantial contribution to achieving them. Thanks to the scientifi c focus of our departments, we are actively supporting the following SDGs: Zero Hunger Clean Water SDG 2 SDG 6 SDG 11 Sustainable Cities and Communities SDG 12 Responsible Consumption and Production SDG 13 Climate Action SDG 15 Life on Land At the bottom of the following pages, you will fi nd a list of our departments addressing the specifi c research area.

LANDSCAPE CROPS PRODUCTS MARKETING Sustainability and cultivation systems DEVELOPING PRODUCTIVE, QUALITY-ORIENTED AND SUSTAINABLE CULTIVATION SYSTEMS FOR SPECIAL CROPS Cultivating grapevines, fruit, vegetables and ornamental plants requires intensive crop management and a high use of resources. Consequently, viticulture and horticulture have to strike a balance between producing suﬃ cient quantities of high-quality products in line with market requirements while acting with an eye to the future, respecting nature and environmental aspects and using resources sustainably. Thus, our research activities focus on the development of innovative and ecological cultivation strategies for special crops. For instance, we are working on cultivating new crop varieties or growth forms that are more adapted to climate change and site characteristics while being more pest-resistant and eﬃ cient in their use of resources, which will lead to reliable yields for producers. Another example includes the test run of intelligent sensor systems to precisely manage and optimize the use of scarce resources like water and nutrients. In addition, we are exploring alternative strategies such as the use of microbial antagonists to control pests, or adding substances to improve site conditions. In cooperation with our partners, we are developing strategies to diversify cultivation systems for special crops in order to safeguard ecosystem services and biodiversity.

LANDSCAPE CROPS PRODUCTS MARKETING Quality, marketing and bioeconomy PROCESSING AND MARKETING AGRICULTURAL (PLANT-BASED) PRODUCTS INNOVATIVELY AND SAFELY – AND BENEFIT FROM THEM IN THE BIOECONOMIC SENSE A sustainable food production ranges from crop production to processing up to the delivery of products to customers. At the same time, these products have to be safe and free of substances that present any health risk. In addition, a sustainable management system must use biological resources, processes and systems more e ﬃ ciently than before. Thus, bioeconomy in food production is crucial to meet sustainability goals, which is why it has become an important part of our research. For example, we are working on the development of energy and resource-e ﬃ cient processing methods for plant products, and we are investigating how to extract and formulate functional ingredients from harvest products and their by-products. Micro-organisms are also examined to establish whether they can serve as protective cultures in food production. As part of our joint research projects with external partners, we are assessing the health effects of plant-based ingredients. The resulting products are carefully evaluated in sensory aspects by our university panel. Market research data, business analyses, and analyses of consumer behavior help to identify trends, especially in wine marketing, and to draw conclusions for future marketing strategies. Our research activities also include analyzing logistic challenges in the food production chain – from producers to customers and from packaging to distribution.

LANDSCAPE CROPS PRODUCTS MARKETING Cultivated landscapes and urban spaces SUSTAINABLE DESIGN AND DEVELOPMENT OF CULTIVATED LANDSCAPES AND URBAN OPEN SPACES Cultivated landscapes and urban spaces have experienced profound changes in the past. Increased land use, for instance, has led to a loss of decisive characteristics and a decline in biodiversity. Social changes and requirements also have a huge infl uence on open space planning in urban regions, where quality of life is mainly determined by the availability of green infrastructure such as green belts and parks. In view of these parameters, our research activities focus on the development of methods to evaluate urban open space design and to assess the social sustainability and performance of urban spaces. For example, we are refi ning processes in the greening of urban spaces, and exploring conditions for the use of plants in cities, especially in the context of climate change. Another research focus includes identifying strategies to adapt landscapes shaped by viticulture in particular to the challenges of climate change, to safeguard biodiversity and to protect individual species in the cultivated landscape. Drawing on the development of sustainable cultivation systems, our research lays the foundation for new production scenarios that foster sustainable and multifunctional cultivated landscapes with a high ecological value and touristic potential.

LANDSCAPE CROPS PRODUCTS MARKETING Climate change, material cycles and life cycle assessments ASSESSING THE RISK OF CLIMATE CHANGE – DEVELOPING STRATEGIES FOR ADAPTATION AND MITIGATION Climate change and its eff ects on temperature and precipitation distribution as well as atmospheric CO2 concentration already have a signifi cant impact on cultivation reliability and conditions for special crops, on material cycles in soils and ecosystems, and on the planning and management of urban green areas and open spaces. Therefore, it is necessary to develop adaptation strategies for viticulture and horticulture, which are in the center of our research activities. We are working on strategies to meet future water demands and to control (new) pests. As part of our research, we are also examining the eff ects of changed climatic conditions on yield, quality, content and fl avor of grapes and horticultural products. In addition, we are developing strategies to reduce greenhouse gas emissions (mitigation) in agriculture and to evaluate these reductions with regard to their CO2 compensation as part of a sustainability assessment. Another key area of our research activities concentrates on the eff ects of climate change on steep slope viticulture, also in view of promoting cultivated landscapes, enhancing biodiversity and, as a result, improving ecosystem services.

LANDSCAPE CROPS PRODUCTS MARKETING Digitization and modeling DIGITIZATION IN THE PRODUCTION AND MARKETING OF SPECIAL CROPS AND LANDSCAPE PLANNING Digital applications have become an important factor along the value chain of special crops. Intelligent technologies and automated processes, for instance, are already used throughout the entire cultivation process, for example for fertilization and crop protection, but also for processing, transport and marketing. Sustainable cultivation, processing and marketing strategies will increasingly rely on digital technologies. In view of these developments, we are working on (non-contact) sensor technology and easy-to-use forecast models to optimize the use of resources, and to identify stress and diseases at an early stage. Digital technologies are also part of process- related applications, for example when using drones to apply plant protection products, or to assess nutrient requirements of specifi c crops. By digitally simulating plant growth and modeling virtual vineyards, we aim to forecast the eff ects of climate change on plant architecture and stress events. In beverage production, modeling complex production steps help us analyze and optimize these processes. An optimized data collection process also enables us to streamline supply chains from producers to customers.

OUR FACE EXPERIMENT: INSIGHTS INTO OUR ATMOSPHERIC FUTURE Since 2014 our scientists have been studying the eff ects of increased atmospheric carbon dioxide concentration on grapevines and vegetables in a one-of-a-kind research infrastructure: our FACE Facilities (Free Air Carbon Dioxide Enrichment). The CO2 concentration within the facilities is increased by about 20 % (to simulate predicted carbon dioxide levels for 2050), allowing us a glimpse into a future with elevated CO2 concentration. Under real-life fi eld conditions with elevated CO2 levels, our scientists are studying soil processes and greenhouse gas fl ows to examine the eff ects on phenology, yield physiology, interactions between plants and pests as well as changes in substances and product quality of grapevines and vegetables. Our Vegetable FACE Facility also consists of six circles measuring 12 meters in diameter each. In four diff erent segments, we are cultivating vegetables in a rotation system to conduct research on the organs of the root (radish), the leaves (spinach) and the fruit (cucumber). In addition to increasing CO2 levels, we can also vary the water supply in the four segments of each circle. The Vineyard FACE Facility consists of six circular areas with a diameter of 12 meters each (three circles are enriched with CO2 while the other three serve as control circles with current carbon dioxide levels). The circles are planted with Riesling and Cabernet Sauvignon (32 plants per circle and variety). CONTACTS | Prof. Dr. Claudia Kammann | Prof. Dr. Manfred Stoll | Prof. Dr. Jana Zinkernagel
OUR RESEARCH VINEYARDS Our university manages 36 hectares of vineyards for academic, research, grapevine breeding and demonstration purposes. 59 percent of our vineyards are planted with Riesling – the classic Rheingau grape – followed by other varieties that are typical for Germany such as Pinot Noir or Müller-Thurgau. This grape variety was named after Prof. Dr. Dr. h.c. Hermann Müller from the Swiss canton Thurgau, who gained worldwide attention as a scientist and also worked in Geisenheim for many years as a botanist, biologist, plant pathologist, grape breeder and teacher. In addition, we also cultivate rather unusual varieties such as the Swiss red wine grapes Gamaret and Garanoir, and the fungus-resistant white wine varieties Muscaris and Calardis Blanc. 1,1 hectares of our vineyards are already planted with fungus-resistant grapes – so-called Piwis – and the number is growing steadily. As part of our research projects we are studying sustainable management systems as well as innovative cultivation and training systems. Our vineyards are managed in an integrated, organic and biodynamic manner. Intelligent sensor systems with modeling features serve as an important tool for making informed decisions on management-related questions. By OLD VINES Does grapevine age aﬀ ect the quality of wine? In a unique research vineyard we are studying Riesling grapes of the same clone and with the same rootstock, which were planted in a standardized booth at diﬀ erent times. As the vineyard was planted in 1971, 1995 and 2012 respectively, we can analyze how grapevine age aﬀ ects the quality of wine made thereof. As part of the project we focus on physiological aspects of the grapevines including yield development, tolerance to water stress and susceptibility to wood diseases. Our research vineyard also allows us to compare chemical compositions and sensory characteristics of wine and must. modeling virtual Riesling grapes, for instance, we are developing new strategies and concepts for the future management of vineyards. We focus on ecologically and economically sustainable management systems and aim to optimize all processes along chain. Combining latest technologies such as autonomous driving, sensor technology and digital land management enables us to identify new ways of managing vineyards. value the CONTACTS | Prof. Dr. Randolf Kauer | Prof. Dr. Manfred Stoll | Florian Müller, B.Sc.
INBIODYN LONG-TERM STUDY Our unique long-term study, initiated in 2006, compares integrated, organic and biodynamic management systems in viticulture. Study ﬁ ndings suggests that organic and biodynamic management systems lead to reduced grape yield and growth rates. The chosen system also aﬀ ects the phenolic structure of the grapes as well as physical and chemical soil parameters. Furthermore, the study shows that organic and biodynamic management systems signiﬁ cantly foster biodiversity. In order to contrast the three management systems, we cultivate the same grape variety under identical site conditions to examine the eﬀ ects on growth and yield as well as grape, must and wine quality. The study also seeks to identify how management systems aﬀ ect soil quality and biodiversity. CONTACT | Prof. Dr. Randolf Kauer EXPERIMENTAL CELLAR OF THE DEPARTMENT OF GRAPEVINE BREEDING In addition to breeding new grape varieties and rootstocks, the Department of Grapevine Breeding houses a biodiversity collection of cultivars and clones from around the world. Clonal selection aims at safeguarding the health and performance of plant material and helps to discover and develop new types with superior traits. As part of our research, we are cross-breeding rootstocks in order to achieve complete resistance to grape phylloxera in leaves and roots combined with horticultural characteristics such as good graft compatibility, superior site adaptation and a positive impact on the grapes of the scion variety. This approach is also used to evaluate fungus-resistant varieties – so-called Piwis. In order to scientiﬁ cally assess diﬀ erent vine varieties and their clones up to the viniﬁ cation process, we vinify them separately in the experimental cellar of our Department of Grapevine Breeding. The viniﬁ cation method in small containers under standardized conditions, called microviniﬁ cation, allows us to bring out the diverse taste and sensory characteristics of the individual varieties and clones. This approach is crucial, especially when vinifying diﬀ erent clones of a single variety, in order to best identify the wines’ typical characteristics. CONTACT | Prof. Dr. Joachim Schmid
OUR (RESEARCH) WINERY The campus winery, which dates back to the beginning of the former research institute, links the three departments of Grapevine Breeding, General and Organic Viticulture, and Enology, and enables us to translate basic and application- oriented research into practical solutions. The winery covers the entire value chain from grapevine breeding to grape production, and from winemaking to marketing. Improving and safeguarding the quality of wine is the cornerstone of our research activities. Since 1996 we have been a member of the Verband Deutscher Prädikatsweingüter (VDP) – the Association of German Prädikat Wine Estates – that proves the high quality of our wines. Our winery covers approximately 24.5 hectares of vineyards used for cultivation and research purposes (excluding grapevine breeding). Our vineyards include outstanding sites in the sub-districts of Geisenheim, Rüdesheim and – given our research focus on steep slope viticulture – the sub-district of Kaub. As the Rhein- gau area is mostly dominated by Riesling, our vine varieties might come as a surprise: although Riesling and Pinot Noir are still taking center stage, they have become increasingly ﬂ anked by other national and international vine varieties. Other departments, such as Bioscience, Beverage Science and Food Safety also beneﬁ t from the infrastructure of our winery. Grapes, must and wines that are not used for research and teaching are matured and sold to customers. Various trial wines from our new product line “Wissensdurst” (“Thirst for Knowledge”) are also on oﬀ er. CONTACT | Prof. Dr. Monika Christmann
DEPARTMENTS OF POMOLOGY AND VEGETABLE CROPS: CULTIVATION AREA AND GREENHOUSES Our Department of Pomology manages 13.6 hectares of for experimental purposes. Cultivated crops include all species typical for German fruit growing, such as apple, pear, plum, sweet and sour cherry as well as quince and walnut. Apples and pears are also cultivated organically. In case of berry fruits, we focus on strawberries, raspberries, gooseberries as well as red and black currants. We use our cultivation area for breeding and breeding research, and for experiments on water supply, quality enhancement and the develop- ment of sustainable cultivation systems. land Our Department of Vegetable Crops conducts research on approximately one hectare of land. With two computer-controlled irrigation carts, more than 200 parcels can be irrigated separately. GPS-controlled planting and seeding technology supports the set-up of exact ﬁ eld experiments to assess the impact of climate change on vegetable production, product quality and plant water relations. Based on ﬁ eld experiments, we develop digital tools for producers to support their decision-making processes. In our greenhouses with a total area of almost one hectare we carry out experiments with fruit, vegetables and ornamental plants throughout the year. Individually-controlled greenhouse units provide perfect conditions for studying the interaction between plants and pests. Starting in 2021, we will modernize our greenhouse facilities in terms of energy eﬃ ciency with a modern, highly transparent glass shell, which will cover our greenhouses (Venlo block construction). The heat supply will be supported by a pyrolysis plant that burns biomass produced at our university, thus creating a modern and low CO2 greenhouse area.

NATURAL PRODUCT ANALYSIS How do technological processing steps inﬂ uence the quality of our food and beverages and how do plant-based food products aﬀ ect our health? Our state-of-the-art laboratory network provides answers to these questions by taking analytical ﬁ ngerprints from plant-based foods and beverages. Verifying product safety and authenticity as well as the best possible preservation of value-deﬁ ning substances is in the center of our attention. To that end, we also closely cooperate with industry partners and nutritionists. Analytical procedures like wet chemical or enzymatic methods play a key role in determining main components. As part of our research projects, we also use various liquid, gas or ion chromatographic procedures as well as molecular spectroscopic methods such as infrared spectroscopy. In order to investigate opportunities and limits of new analytical procedures, we use quantitative 1H-NMR spectroscopy (Nuclear Magnetic Resonance) to prove the authenticity of a product. Within just 15 minutes, for instance, we are able to distinguish direct juice from juice made of concentrate and thus identify possible counterfeits. Additionally, we seek to address some ultra-complex analytical issues that have often remained unresolved to date, such as determining the geographic origin of a food product by using a high-resolution ion mobility mass spectrometer (timsTOF) that was only procured in June 2020. The mass spectrometer, funded by the German research funding organization DFG, also provides valuable insights into the molecular composition of a food product in unprecedented depth. In current research projects, for instance, we aim to identify the molecular causes of a diet rich in fruit and vegetables, which is undeniably associated with health beneﬁ ts. To that end, we closely cooperate with agricultural researchers and nutritionists in order to track the metabolic fate of plant-based substances in food products and beverages. In view of the guiding principle “from crops to clinic”, our aim is to trace health-promoting eﬀ ects back to the responsible plant compounds. CONTACT | Prof. Dr. Ralf Schweiggert
GEISENHEIM YEAST BREEDING CENTER AND YEAST FINDER 125 years of yeast breeding in Geisenheim. As Germany’s ﬁ rst facility to produce pure yeast cultures for wine fermentation, the Yeast Breeding Center was founded in 1894 and directed by Dr. Julius Wortmann based on the studies of Louis Pasteur and Prof. Emil Christian Hansen and supported by the “Deutscher Weinbauverein” (German Winegrowers’ Association). In the years to come, institutes around the world followed the lead. Today, the Geisenheim Yeast Breeding Center is part of our Department of Microbiology and Biochemistry. Over the last decades, the center has collected a large number of yeast strains and has tested them for their fermentation pro- perties and practical use. Additionally, the center has also tested fermentation processes for potential oﬀ -ﬂ avors and their causes. In the future, we aim to step up our work to include new research areas covering non-conventional yeasts. The Geisenheim Yeast Finder provides an overview of pure yeast strains that are currently available on the market. Based on information about must and grapes, the free-of-charge online tool (www.geisenheimer-hefeﬁ nder.de) selects suitable starter cultures for individual fermentation purposes. Upon answering 17 questions on grapes, must and chosen wine style, the program compares the input with the properties of the listed yeast strains. Information about yeast properties, e.g. fermentation at low temperature, nutrient require- ments and possible fermentation bouquets, comes from the yeast producers. After running a comparison, the online tool lists suitable yeast strains and indicates the percentage of the match. In addition, the tool provides the commercial name of the product, the producer and the website for further reference. We have seen increased access to our portal in years with low yields and/or increased grape rot or even drought stress. ´ CONTACT | Prof. Dr. Jürgen Wendland
CLONE COLLECTION OF OUR DEPARTMENT OF GRAPEVINE BREEDING The Department of Grapevine Breeding manages Germany’s second largest collection of genetic resources of grapevines. For rootstock breeding, we use diﬀ erent wild forms of the vine. Our collection covers more than 20 diﬀ erent Vitis species, including more than 2,000 individual forms of Vitis berlandieri alone. Based on our collections, our aim is to breed new rootstocks that show complete resistance to grape phylloxera, high tolerance to lime-rich soil, good site adaptation and high scion aﬃ nity. Safeguarding the best possible diversity within our traditional grape varieties is key to the future of grapevine breeding. Geisenheim houses a major Pinot collection and the world largest collection of Riesling cultivars with more than 1,000 accessions, which serve as a genetic pool for selecting future clones. CONTACT | Prof. Dr. Joachim Schmid SENSORY LABORATORIES AND SENSORY PANEL In our two sensory laboratories in the Department of Enology we evaluate sensory characteristics of food products with our human senses. The laboratories are equipped with 54 test stations to teach and apply analytical sensory testing procedures, product develop- ment and quality control. By using colored light or by completely darkening the room we are able to evaluate products irrespective of their visual impression. Wine, sparkling wine and plant-based foods are particularly evaluated in sensory aspects in order to identify, for example, how changes in the production or diﬀ erent storage conditions aﬀ ect their sensory perception. Our ﬁ ndings are linked with marketing and production results and analytical data. As part of consumer research projects, our sensory laboratories help to assess acceptance and preferences in terms of food choices. Our Sensory Panel includes experienced staﬀ members from diﬀ erent university departments. It evaluates test samples from scientiﬁ c research projects or exter- nal customers and explores new sensory methods and their applicability.

BEVERAGE TECHNOLOGY CENTER Our beverage technology research covers the entire value chain and product range – from fruit and vegetable-based beverages and soft drinks to coﬀ ee and plant-based milk substitutes up to beer, wine and liquors. Thanks to its technical equipment and ﬂ exible functionality, the current Bever- age Technology Center (GTZ) and the planned new building with almost 4,000 m² in particular provide unique opportunities to combine research and teaching with a practical focus. The current GTZ houses state-of-the-art brewery and distillery facilities and various technologies to produce non-alcoholic drinks, e.g. fruit and vegetable juices, and to process plant-based raw materials in general. The planned new building will also include a production facility for sparkling wine. Our three breweries serve diﬀ erent purposes: a conventional brewery with an 80 l scale is available for our teaching activities. For research activities in line with Good Laboratory Practices we use a semi-automatic facility on a 20 l scale. A brewery on a 150 l scale, equipped with a dynamic ﬁ ltration system (Nessie and VaculiQ), is available for examining new processes for solid-liquid separation as an alternative to the lauter tun. The GTZ also houses two roasters – drum roaster and ﬂ uidized bed roaster – for roasting coﬀ ee, cocoa, nuts and oilseeds. By closely combining technology-related activities of the GTZ with the analytical expertise provided by the Department of Beverage Research, we are setting new standards in the respective degree programs and in beverage research.

THE UNIVERSITY GROUNDS METEOROLOGICAL NETWORK AND WEATHER FAX A high-tech meteorological network consisting of 13 weather stations located in the Rheingau and Hessische Bergstrasse regions forms the basis for forecasts, which we supply to over 350 winegrowers as a “weather fax” – now mostly online – to help them make informed wine-growing decisions. In addition to air temperature, relative humidity, precipitation, wind speed and global radiation, each station also measures the temperature 70 cm above ground, which roughly corresponds to the point at which the vine bends. These data are used, among other things, to forecast infestation with the pathogen that causes downy mildew (peronospora), vine development and to calculate leaf area per shoot. The readings also help us to better understand the eﬀ ects of climate change and its implications for viticulture. Two historical parks serve as the “lungs” of our university, while also actively symbolizing the link between research and teaching. Extending over a total of ﬁ ve hectares, the area is divided into the university park around the Administration Building and Monrepos Park, which surrounds the neo-classical Villa Monrepos. Heinrich Eduard von Lade, the founder of the Königlich Preussische Lehranstalt für Obst- und Weinbau zu Geisenheim, had a broad range of interests and built the latter as his retirement home between 1860 and 1863. Simultaneously, the park was laid out based on the model of an English landscape garden and – following the tradition of a demonstration and educational garden – underwent signiﬁ cant changes during the terms of oﬃ ce of the various Institute directors. Today, its design features are considered a rare example of the formal gardening language typical of the 1950s and 1960s. Further highlights of the Monrepos Park include its large open spaces featuring an impressive sequoia, Lebanon cedar and oriental arborvitae. CONTACT | Meteorological Network: Dipl.-Ing.

GEISENHEIM BUSINESS ANALYSIS As part of the Geisenheim business analysis, our Department of Wine and Beverage Business has been assessing the economic success of German wine estates for over 30 years now. Within the framework of our analysis, participating wineries get an overview of their current economic situation and improvement potential. Due to structural changes in the wine industry, economic performance has become a crucial factor over the last years – only economically successful wineries will have a future and ﬁ nd a successor. Therefore, we have fundamentally revised the project and developed a new graphic evaluation of the wineries' economic performance over the last ﬁ ve years. Our aim was to make the evaluation more comprehensible so that winegrowers can better implement the results in their day-to-day business. So far, more than 700 wine estates have beneﬁ ted from our analysis. The project is funded by the Federal State of Rhineland-Palatinate, the Hessian Ministry of Higher Education, Research, Science and the Arts and the European Union. The extensive collection of trees and shrubs in the university park still includes several specimens from the period in which it was originally laid out – a collection of non-native plants that reﬂ ects the spirit of the era. Exotic species and rarities, such as the Osage orange (Maclura pomifera), the edible persimmon or the cut-leaf walnut delight plant enthusiasts. Another impressive variety is the black walnut, which is one of the largest specimens in Germany with a trunk circum- ference of over 4.80 meters. The “Iris Garden” is home to a digital beehive, which is part of a worldwide network of high-tech beehives researching how environmental factors impact bees. These inviting surroundings also provide the stage for our graduation ceremony every summer. CONTACT | University grounds: Prof. Dr. Alexander von Birgelen CONTACT | Prof. Dr. Simone Loose
UNIVERSITY RESEARCH GARDEN WE4BEE – THE SECRET LIFE OF BEES Hochschule Geisenheim University maintains a study and research garden on the university grounds since 2020. The garden provides the perfect framework for designing, building and managing construction projects that are typical for our industry, e.g. paths, terraces, walls and staircases. In collaboration with students and the interested public, we are also creating special constructions, for instance fully automated irrigation systems, natural self-cleaning swimming ponds, light and sound installations as well as possibilities for the autonomous maintenance of vegetation areas. Our research garden is much more than just a simple showground – from the very ﬁ rst day, we collect ecological data (material and energy consumption) of buildings and construction materials to assess them in ecological terms and carry out life cycle assessments, which are the basis for building information modeling and sustainable construction. Tailored sensor and measurement technology records adverse eﬀ ects of climate change such as heavy rainfalls and water shortages in plants. In collaboration with industry partners, we are investigating the scope of these eﬀ ects to identify structural solutions. For example, we are working on a tailored and site-speciﬁ c irrigation process including an intelligent control system as well as decentralized inﬁ ltration units and open-pore path and square pavements. The key focus of our study and research garden is to provide answers to future questions and challenges posed by climate change. The showground for con- struction technology in landscape gardening is open for students, the interested public, landscape architects as well as garden and landscape designers. CONTACT | Prof. Dr. Andreas Thon The citizen science project “we4bee” seeks to illustrate the behavior and needs of honeybees. As part of the project, 100 fully electronic beehives were distributed – one of which has also been located at our university since the beginning of 2020. This special beehive called TopBarHive is equipped with a temperature sen- sor on the inside of the hive and a sensor for wind, light intensity and precipi- tation on the outside. Every 15 minutes the sensors transmit data to the project network by using a LAN connection. In addition to high-tech sensors, cameras have been installed on the inside of the beehive and opposite its entrance to collect data on living and environmental conditions of bee colonies. The “we4bee” app allows users to retrieve data and to view recordings. As part of the project, the University of Würzburg evaluates the collected data by means of big data analytics and machine learning methods and provides the results to the general public. In addition to the “we4bee” project, our interdisciplinary master’s module “The Bee” gives students more detailed insights into bee- keeping, the beehive and its environmental parameters, thus creating connections to our various master’s programs. Students learn strategies for preserving and enhancing biodiversity in diﬀ erent cultivated landscapes, which is exactly the focus of “we4bee”.
