Hybrid Symposium // Symposium on the Food-Water-Energy Nexus

Increasing water scarcity, growing population, warmer climate - how will these affect the future supply of cities with energy, water and food? How do we set the course today to ensure a secure and sustainable supply in the future? On September 14 and 15, the Stuttgart University of Applied Sciences (HFT Stuttgart/Germany) will host the Symposium on the Food-Water-Energy Nexus to mark the conclusion of the IN-SOURCE project. The project team has explored the FWE nexus for case studies in New York, Vienna and the German district of Ludwigsburg and will present their results for discussion at the symposium. Other FWE projects and researchers are welcome to share their findings and experiences. The symposium is planned as a hybrid event. Participation is free of charge.

About the event

A CityGML based shared urban platform development to maximise synergies in the food, water and energy sectors is in the focus of the FWE IN-SOURCE project. Coordinated at the HFT Stuttgart, teams in Vienna, New York City and Stuttgart work jointly on technological and socioeconomic research questions. In this final event, the project team would like to present their results as well as exchange experiences with other FWE Nexus projects.
