Street Science: Community Knowledge for Global Health Equity

Street science is the processes used by community residents to understand, document, and take action to address the environmental health issues they are experiencing. Street science is an increasingly essential process in global urban health, as more and more people live in complex environments where physical and social inequalities create cumulative disease burdens. Street science builds on a long tradition of critical public health that values local knowledge, participatory action research, and community-driven science, sometimes referred to as “citizen science.” Street scientists often partner with professional scientists, but science from the street does not necessarily fit into professional models, variables or other standards of positivist data. Street science is not one method, but rather an approach where residents are equally expert as professional scientists, and together they co-produce evidence for action. In this way, street science challenges conventional notions in global health and urban planning, which tend to divorce technical issues from their social setting and discourage a plurality of participants from engaging in everything from problem setting to decision-making. Street science does not romanticize local or community knowledge as always more accurate or superior to other ways of knowing and doing, but it also recognizes that local knowledge acts as an oppositional discourse that gives voice to the often silent suffering of disadvantaged people. At its best, street science can offer a framework for a new urban health science that incorporates community knowledge and expertise to ensure our cities and communities promote what is already working, confront the inequities experienced by the poor and vulnerable, and use this evidence to transform the physical and social conditions where people live, learn, work, and play.
