This week a new open access paper came out in a special issue (monograph) of Current Sociology about Social Impact Assessment. The special issue was led by Guadalupe Ortiz and Antonio Aledo, and their introductory essay is worth a read, as is Frank Vanclay’s epilogue, reflecting on 50 years of SIA and asking “is it still fit for purpose?”. Our offering, Social media and social impact assessment: Evolving methods in a shifting context, reflects on a decade of research using mostly Instagram to understand the social impacts of developments such as hydroelectricity, wind energy and coastal dyke realignment. The above demonstrates the current state of the art in terms of workflows, and shows how several of our studies have navigated those options. The paper also talks about the challenges, practical and ethical, of using social media datasets, and calls for government support in securing ongoing access for the purposes of public good research, a topic also recently argued by Ethan Zuckerman in Prospect Magazine. Most of the work synthesized in this paper has been published elsewhere, except the brilliant work that Mehrnoosh Mohammadi did on developing a collage approach to communicating common features in social media images to protect both copyright and privacy concerns (see below). This is a method we advocated back in 2017 and it is wonderful to see it in action.
