Judith Riedel completed her doctorate at the Swiss Federal Institute of Technology (ETH) and worked as a member of the scientific staff at FiBL (Research Institute of Organic Agriculture) from 2013 to 2020. She is an internationally experienced ecologist with sound expertise in statistics and biodiversity research as well as a wealth of expertise in the successful coordination of scientific teams. Her research work focuses on biodiversity, agroecology and sustainability. Both sound scientific analysis and knowledge transfer and exchange with practitioners are pivotal to her work.

“I’m interested in the interactions and interconnections in ecosystems and in biodiversity and its significance for humans. We are embedded in complex global networks and all our actions have consequences for people on the other side of the world; food systems must change. Innovative agroecological farming offers solutions to this challenge that can be both sustainable and economically profitable. If from the start we consider the ultimate consequences of processes and focus on practical implementation, we can together be successful in implementing the United Nation’s development goals and instigate change.”
