The Limits of Food Production – Vertical Farming – Day 1, HEF Agrarwissenschaftliches Symposium 2021

For the first time in its history, the “HEF Agrarwissenschaftliches Symposium” will be held as a two-day international scientific conference. The first day will be held completeley in English, while the second day will be held in German language.

While food demand continues to increase with a growing global population, climate change and soil degradation have made it already difficult to ensure food security in some regions. Hence, producing more food in a more sustainable way constitutes a central agricultural challenge. An alternative for growing crops in the field has emerged in recent years with vertical farming. With LEDs becoming affordable and more efficient, the economics of indoor and vertical farming are redefined. In vertical farms, all growth factors including light, temperature, humidity, CO2 level, ventilation, water and nutrients can be controlled and optimized. Simultaneously, weeds, pests and diseases can be excluded, and the use of water and fertilizer can be drastically reduced. The aim of this conference is to discuss the current state of science in controlled-environment crop growth and vield, and to detemine the limits of food production in vertical farms.

The event will be held as hybrid event with a limited amount of participants on-site and unlimited access via the live-stream on Youtube. Viewers on Youtube may interact and ask questions during the event by accessing the interaction tool slido:
