“…The health and nature research is presented with a heterogeneous selection of terminology, including 'green space' (Conniff andCraig, 2016, Bell et al, 2014) and 'blue space' (White et al, 2010, Bell et al, 2015 referring respectively to land and water areas identified as 'natural' to varying extents and distinct from 'grey' urban and industrial spaces. A wider array of terms is applied in the research to describe the particular wellbeing focused activities that go on in these 'natural' spaces including 'eco-therapy' (Wilson et al, 2008), 'social and therapeutic horticulture (STH)' (Diamant and Waterhouse, 2010), 'care farming' (Leck, Upton and Evans, 2015), 'forest bathing' (Ochiai et al, 2015), 'adventure therapy' (Willis, 2011), and 'green exercise' (Olafsdottir, Cloke and Vögele, 2017). Terms are sometimes combined, such as green exercise referring to fitness activities occurring in green spaces, or are treated separately with green space and blue space as more abstract population-level constructs and adventure therapy (for example) taking place in more vaguely defined spaces.…”
