Our Research Focus

Sustainability and Cultivation Systems

Developing Productive, Quality-Oriented and Sustainable Cultivation Systems for Special Crops

Cultivating grapevines, fruit, vegetables and ornamentals requires intensive crop management and a high use of resources. Consequently, viticulture and horticulture have to strike a balance between producing sufficient 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 efficient 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.

Quality, Marketing and Bioeconomy

Processing and Marketing Agricultural Plant-Based Products Innovatively and Safely – Respecting Bioeconomy

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 from harmful substances. In addition, a sustainable management system must use biological resources, processes and systems more efficiently 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-efficient 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.

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 influence 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 refining 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 tourist potential.

Climate Change, Material Cycles and Environmental Footprint

Assessing the Risk of Climate Change – Developing Strategies for Adaptation and Mitigation

Climate Change and its effects on temperature and precipitation distribution as well as atmospheric CO2 concentration already have a significant 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 effects of changed climatic conditions on yield, quality, content and flavor 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 effects of climate change on steep slope viticulture, also in view of promoting cultivated landscapes, enhancing biodiversity and, as a result, improving ecosystem services.

 

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 specific crops. By digitally simulating plant growth and modelling virtual vineyards, we aim to forecast the effects 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.

On May 8–9, 2025, the 11th Anwendertreffen Weinanalytik, or Wine Analysis User Conference, took place at Hochschule Geisenheim University. This conference is an established forum for professionals involved in wine and wine analysis. Over 130 participants from wine labs, vineyards, inspection agencies, research institutes, suppliers, and appliance companies throughout Germany, Austria, and Switzerland convened in Geisenheim to discuss pressing issues in the field of wine analysis.

The conference’s multi-faceted program focused on modern analysis methods, sensory assessment issues, microbiological diagnostics, and new approaches to automatization and digitization. Contributions ranged from practical applications to innovative research approaches that aim to meet the challenges of a changing wine industry. Special emphasis was placed on praxis-oriented solutions for the sector: rising demands, increasing economic pressure, and changing consumer behavior require new approaches in both production and analysis. As a result, the dealcoholization of wine became a major topic of discussion during the conference, particularly at the evening event, which featured a wine tasting that included dealcoholized products.

Having taken place regularly since 2001, the conference once more proved to be an invaluable platform for the exchange of expert knowledge, the safeguarding of quality in practice, as well as networking between researchers and industry players.

The conference was held at Hochschule Geisenheim University’s newly opened Lecture Hall Building – a visible symbol of the university’s growth and forward-looking vision, as it continues to actively respond to current challenges with new degree programs, new professorships, and a strong sense of community.

We would like to thank all participants and contributors for two days full of inspiration, discussions, and shared ideas, and we look forward to the next conference at the State Viticulture Institute in Freiburg in 2027!
