Since March 2023 ConservES - Living-lab approach to floral enrichment as a tool to conserve biodiversity and maximising ecosystem services in European agricultural landscapes
Role: Principal invesitgator, researcher
Funder: BioDivERSA/Bundesministerium für Bildung und Forschung
Start time: 01/03/2023
End time: 28/02/2026
Modern agriculture in Europe is the driving force behind the simplification of ecological networks and the loss of biodiversity in agricultural landscapes. ConservES aims to maintain biodiversity in intensive agro-ecosystems through flora enrichment (combined flower strips and hedgerows) and to promote associated ecosystem services, i.e. natural processes such as pest and weed control or pollination. For this purpose, ConservES uses Europe-wide climate and landscape gradients to gain better insights into potential interactions with the environment. Floral enrichment is planned and implemented using an innovative living lab approach, a cooperation with stakeholders from the academic, business, public, and civil society sectors. This promotes regional, effective and long-term solutions for the conservation of biodiversity and provided ecosystem services in agroecosystems. Within the project, the university of Würzburg is investigating the impact on biodiversity in German agricultural landscapes and the influence on production-relevant ecosystem services.
Since 2022 COST Action CA21134 - Towards zer0 Pesticide AGRIculture : European Network for sustainability (T0P-AGRI-Network)
Role: Member of Management Committee
Current crop protection in EU agriculture is heavily reliant on chemical pesticides to suppress weeds, pests and pathogens. In view of the serious health and environmental consequences, European public authorities, consumers, and society at large are demanding drastically reduced use of chemical pesticides, in the context of a production of safe, high-quality and affordable food. Furthermore, farmers are calling for research and innovation solutions to protect crops with non-chemical means while maintaining a viable farm economy. A change of direction and paradigm is needed to foster this transition, emphasizing preventive crop protection based on agroecological practices that to prevent pest outbreaks and infestations. The proposed Cost Action T0P-AGRI-Network targets the transition “Towards zer0 Pesticide AGRIculture”, aiming at preparing the future of an agriculture free of synthetic pesticides and of nature-derived pesticides that negatively impact environment and human health. T0P-AGRI-Network tackles this challenge by create and organize a wide research community with the aim to form a European leading network with high and transdisciplinary expertise around the common objective of pesticide-free agriculture, with a particular focus on young scientists. To enable a redesign of the food system as a whole, T0P-AGRI-Network will promote a concerted mobilization of scientists, farmers, processing industries, public authorities and consumers by associating them closely with the activities that will be carried out in the Cost Action.
Since 2018 LandKlif - Effects of climate change on biodiversity and ecosystem services in natural, agricultural and urban landscapes, and strategies to management of climate change
Role: Project coordinator, researcher
Other members of the lab involved in project: Ingolf Steffan-Dewenter, Jie Zhang, Thomas Hovestadt, Jörg Müller, Ute Fricke, Cristina Ganuza
Climatic conditions and land use have a significant impact on habitats, biodiversity and ecosystem services. The transformation of semi-natural habitats into agricultural areas or settlement changes the species inventory, the provision of ecosystem services and the adaptation potential of ecosystems to changing climatic conditions. At the local level, there is often a positive correlation between biodiversity and ecosystem functions. However, until now, studies on the following aspects are still missing: (1) how climatic gradients and the landscape composition and configuration influence the biodiversity and the provision of ecosystem services, (2) which interactions exist between climatic conditions and land use, (3) whether biodiversity at population, species community and landscape level improves the resilience against climate change and extreme climatic events. The LandKlif Network investigates the biodiversity and multi-functionality of semi-natural, agricultural and urban landscapes in different climate zones of Bavaria, in order to answer these questions and to develop options for the mitigation of climate change as well as the adaptation to changing climatic conditions. The three landscape types differ fundamentally in the level of anthropogenic impact, biodiversity, and ecosystem services which they provide to the society. A better understanding of the interactions between landscape structure, regional climate change and ecosystem responses is an important basis for developing strategies to climate change mitigation and regional adaptation to its consequences.
2013 - 2018 EU project FP7 LIBERATION: Linking farmland biodiversity to ecosystem services for effective ecofunctional intensification
Role: Researcher
Other members from the lab involved in project: Emily Martin, Ingolf Steffan-Dewenter, Audrey St-Martin
The next few decades will witness a rapidly increasing demand for agricultural products. This growing demand needs to be met largely through intensification (produce more from the same land surface) because there is little scope for an increase in agricultural area. Ecological intensification has been proposed as a promising solution.
Ecological intensification is the optimization of all provisioning, regulating and supporting ecosystem services in the agricultural production process. LIBERATION aims to provide the evidence base for ecological intensification and demonstrate the concept in seven representative agricultural landscape types in Europe. Using existing datasets from past and on-going European-scale studies we will first identify general relationships between the configuration of semi-natural habitats, on-farm management and biodiversity in a range of European landscapes and farming systems. Using a modelling approach we will link biodiversity to ecosystem services, by determining relationships between biodiversity, the delivery of multiple ecosystem services and agronomic yield.
A novel aspect is that LIBERATION considers above- and below-ground ecosystem services simultaneously and analyses synergies and trade-offs between different ecosystem services. Using this modelling approach we will analyse which on-farm management practices and spatial configuration of semi-natural habitats optimizes yield and which optimizes farm income.
Examples of ongoing research within the Liberation framework
1) Above- and belowground interactions in winter wheat fields. Effects of soil quality and landscape complexity on parasitoid and predator abundances. Large-scale field experiment conducted in seven European countries involved in Liberation:
2) Importance of birds and crop diversity for biological control in cereal agroecosystems
3) Interactive effects of soil quality and landscape complexity on sunflower pollination.
