Agriculture and Ecosystem Services

Agriculture and Ecosystem Services

Our mission

Our group focuses on how agricultural and environmental policies affect both people and nature. We study how they influence farmers’ wellbeing and actions as well as biodiversity and ecosystem services in agricultural landscapes. We want to understand how agricultural systems work at a societal and ecological level, and find out how they could be made more sustainable. Throughout, we want to deliver scientific knowledge that can have an impact on policies and practices.

Current Projects:



 “Leverages and potentials in the Common Agricultural Policy for improved support of Green Infrastructure, biodiversity and ecosystem services”

Daniel Vedder, Lea Kolb, Lea Kahoun, Judith Rakowski

In CAP4GI ("CAP for Green Infrastructure"), we want to find out how the CAP (beyond agri-environment schemes) affect the work of farmers in Germany and how economically and ecologically useful they are. To do so, we use a two-stage computer model to explore how the policy context affects farmers’ decisions and thus shapes the agricultural landscape, and how this subsequently affects biodiversity and ecosystem services.

“Impacts of the Common Agricultural Policy on Biodiversity, Ecosystem Services and people”
Guy Pe’er, Aletta Bonn, Carla Cerda

Aims to examine how different CAP instruments affect biodiversity, ecosystems and farmers across the EU; and to deliver science-based recommendations to improve the CAP’s design and implementation. Our current analytical work focuses on butterflies, to investigate how different CAP instruments affect biodiversity through changes in farmers’ land management choices. Science-policy interactions are taking place at various levels, promoting close and frequent interactions with policymakers to synthesise and deliver recommendations for improved performance of the CAP toward its biodiversity objective.
