Design  impacts  everyday  life,  shaping  the  way  we  engage  with  the  world  and   those around us. This is not simply limited to the ‘us’ as human beings but also the many other species we share the planet with. Viewed in this way our collective future may seem uncertain given the many challenges we now face. The idea that design should be only human-centred seems increasingly questionable given the impacts we have made upon the planet. Design has had many benefits, and in some cases been literally life-saving. However, it has also led to  serious environmental damage, destruction of ecosystems and habitats, pollution, risking animal lives, and continues to contribute towards climate change. This talk will explore how we might design for a more-than-human world. It will draw upon current projects from the Dark Design Lab at Lancaster University to illustrate how we might better think of and design for places at night. It uses practice-based design research to better understand what happens after dark and develop suitable strategies to promote biodiversity, safety, and sustainability for all us living in a more-than-human world.
