Social issues are becoming increasingly pressing. From dementia to climate change to corona; we as people, citizens, residents and city users - through our own experience or otherwise - have a sense of them. However, truly understanding and addressing these issues is difficult because there is no single owner. Everything is related, intertwined and also changing. Getting an overview and deciding together on necessary steps proves difficult. Complex issues thus become orphaned. Design and more specifically co-design - creative collaboration with others - is increasingly seen as a possible approach to these such issues and collaborations because it can deal with complexity and uncertainty, is optimistic and investigative in nature. With a co-design approach, we can find a shared desire and with that we connect with each other. By then searching together for mechanisms that can lead to the desired values, we gain insights on how to tilt a problematic situation. That enables us to imagine alternative futures. These help us on our way to a better, greener and more social world and social change.
