This handbook takes an international, intergenerational, lifespan approach to address how being in nature and outdoor learning can contribute to wellbeing, with a focus on everyday spaces, equity, playful, creative, inclusive perspectives. Featuring 25 chapters written by academics and practitioners based in Canada, Finland, India, Iceland, Ireland, New Zealand, Spain, Slovenia, the UK and the USA the handbook covers six over-arching themes: Taking Notice; Connecting; Learning; Being Active; Giving and Slowing Down. The authors explore playful, nature-based activities and thinking that offer ways of learning about the outside world and understanding our place within it. Set against a backdrop of some of the most pressing problems facing us, including climate change, conflict, war, biodiversity loss and us etc., the chapters challenge the reader to find positive ways for humans to coexist more sustainably with each other and the 'more-than-human' world.
