On the one hand, urban planning aims to make optimal use of land for settlement and transport and to enhance its ecological value at the same time. On the other hand, many city dwellers become active in urban gardening and greening from roof gardens to balcony biotopes to seed bombs for dreary lawns and fallow land. In this way residents continue to tell the future narration of their city as green oases, areas of small self-sufficiency and mini-biotopes.
Many urban planners already support these developments yet there are questions and uncertainties among all participants.
What can individual citizens contribute to making cities greener and more ecological? Will a concept of a climate‐friendly and healthy city grow over this ‐ in the truest sense of the word? And how specifically can urban and private areas be gardened? What are private and municipal strategies for dealing with urban gardens and their implementation? What are the costs to cities of private urban gardening? Which horticultural and which structural engineering aspects have to be considered? Which psychological and healthy effects does a green city have on its inhabitants? What kind of biodiversity exists in green cities? These exemplary questions form the thematic framework of the course. The questions can only be dealt with and answered within an interdisciplinary framework. Therefore, a group of students from different disciplines and universities at different locations is desirable. The students will decide which sub‐questions of this complex topic we will pick out or which we will further differentiate.
