Book excerpt: This volume interrogates the intertwining of the local and the digital in environmental communication. It starts by introducing a wave metaphor to tease out major shifts in the field, and situates the intersections of local places and digital networks in the beginning of a third wave. Investigations that feature the centrality of place and digital communication platforms show how we today, as researchers and practitioners, communicate the environment. Contributions identify the need for critical approaches that engage with the wider consequences of this changing media landscape, unpacking local and global tensions in environmental communication research. This empirical case study collection from different parts of the world shows that environmental activists and citizens creatively use digital technologies for campaign purposes. It identifies new environmental communication challenges and opportunities, as well as practices, of environmental activists, NGOs, citizens and local communities, in the fight for social and environmental justice.
