In the 2018/2019 winter semester, student Elisabeth Ziegler developed an audio tour with 19 audio stations on the Sustainable Development Goals in the tropical greenhouse. This was part of her Bachelor's thesis in the Department of Ecological Agricultural Sciences. The Sustainable Development Goals were adopted as a global agenda by the United Nations in 2015. The audio tour uses individual plants to explain the sustainability goals defined therein. The tour can be listened to on your own smartphone during a visit to the greenhouse, but can also be found online here:
