Through twelve ethnographic case studies,The Social Life of Standardsreveals how standards - political and technical tools for organizing society - are developed, applied, subverted, contested, and reassembled by local communities interacting with norms often created by others. Contributors explore standards at work across different countries and contexts, such as Ebola biomedical safety precautions in Senegal, Colombian farmers contesting politicized seed regulations, and the application of Indigenous standards to Canadian environmental assessments.
