Resistance is in the air: From post-politics to the politics of expertise

Knowledge about air pollution is key, both to contest the status quo and to propose a different environmental imaginary as to how urban reality should be. Empirically, this paper focuses on Brussels and its history of air pollution contestation over the last fifty years, in order to trace how knowledge dynamics shape the politics of air. Theoretically, the paper offers a critical reading of the ‘post-political city’ literature that has been omnipresent in urban studies, human geography and political ecology over the last decades, in order to offer a more sophisticated theorization of expertise and knowledge. The paper offers at least three key insights. First, lay as well as public knowledge is of key importance in making air pollution manifest as a matter of concern. Making a perceived problem visible to a wider public in itself can be transformative and can pressure governments to respond, albeit rarely adequately. Second, the use of scientific knowledge by social movements and civil society plays a central role in contesting established priorities and in developing counter strategies, often alternating lay knowledge and more formal scientific knowledge in the process. At the same time, scientific knowledge and other forms of specialized expertise also play an important role in solidifying existing hierarchies of authority. Third, our analysis points to the centrality of the state as an arena for political action and to the importance of a politics of shifting blame and responsibility onto other layers of government or other societal actors.
