Impact assessments used by large-scale development projects are often portrayed as neutral tools providing objective and value-free information to decision-makers. However, scholars widely agree that impact assessments are inherently biased, political, and distorted by power dynamics. Using a forthcoming natural gas project in Mozambique as case study, my ethnographic field research provides important baseline study of the social, relational, and place-bound aspects of wellbeing, often overlooked in impact assessment processes.
