Social scientists have become increasingly interested in human-environment interactions. Alongside this, policy instruments are grappling with how sustainability and human wellbeing can be simultaneously enhanced. My research aims to further the concept of relational wellbeing to connect ideas around stewardship, care and empathy. Using qualitative research methods – such as walking interviews and photo-elicitation workshops – I will analyse how resource-users and the public, more generally, experience blue-green spaces and the impact this has on their relational wellbeing. This research aims to contribute new knowledge on human-environment interdependency and how sustainability and wellbeing can be fostered for those interacting with blue-green spaces.
