Sensing Environments, Inventing Citizens (lecture) Citizen sensing practices that monitor and measure environmental problems, such as air pollution, are emerging everywhere. They generate data used for action against policy and regulation. But does the rise of citizen sensing practices and technologies re-inscribe instrumental, potentially reductive approaches to citizenship and political engagement? Or, do the instruments, like lowcost environmental sensors, challenge this apparently linear logic through attempting to realise political change? How effective are these practices of citizen sensing, not just in providing crowd-sourced data sets, but also in giving rise to new modes of environmental awareness and practice? www.jennifergabrys.net
