The European Society for Environmental History has awarded Postdoctoral Scholar Chanelle Adams the 2025 Bristol-Bern Prize in Public Environmental History for her project "Ghost Tours: The Haunt of Environmental Degradation and Colonialism."

Ghost Tours seeks to uncover and confront the entangled legacies of colonialism and ecological crisis by transforming overlooked public spaces into immersive platforms for critical reflection, using art, archival research, and performance to illuminate the hidden histories that continue to shape our environments today.

The Bristol-Bern Prize committee emphasized that it "was particularly impressed by the emphasis on participatory and local collaboration, which helps connect the histories of local landscapes with the politics of colonialism and capitalism." The committee highlighted the project’s impressive variety of international performances and range of open-access materials, adding that the project "truly pushes the boundaries of contemporary environmental history."

The Bristol-Bern Prize encourages researchers to situate public engagement in their work in environmental history, to support an understanding of the past towards building more sustainable futures.
