A new wave of smart-city projects is underway that proposes to deploy sensorbased ubiquitous computing across urban infrastructures and mobile devices to achieve greater sustainability. But in what ways do these smart and sustainable cities give rise to distinct material—political arrangements and practices that potentially delimit urban ‘citizenship’ to a series of actions focused on monitoring and managing data? And what are the implications of computationally organized distributions of environmental governance that are programmed for distinct functionalities and are managed by corporate and state actors that engage with cities as datasets to be manipulated? In this paper I discuss the ways in which smart-city proposals might be understood through processes of environmentality or the distribution of governance within and through environments and environmental technologies. I do this by working through an early and formative smart-city design proposal, the Connected Sustainable Cities (CSC) project, developed by MIT and Cisco within the Connected Urban Development initiative between 2007 and 2008. Revisiting and reworking Foucault's notion of environmentality in the context of the CSC smart-city design proposal, I advance an approach to environmentality that deals not with the production of environmental subjects, but rather with the specific spatial—material distribution and relationality of power through environments, technologies, and ways of life. By updating and advancing environmentality through a discussion of computational urbanisms, I consider how practices and operations of citizenship emerge that are a critical part of the imaginings of smart and sustainable cities. This reversioning of environmentality through the smart city recasts who or what counts as a ‘citizen’ and attends to the ways in which citizenship is articulated environmentally through the distribution and feedback of monitoring and urban data practices, rather than through governable subjects or populations.

Sensors are increasingly present in our environments and technologies. At the same time, environmental sensing is a set of practices meant to provide more information on environmental change, while enabling new forms of environmental citizenship. Program Earth documents and discusses the ways in which new environments and citizen-sensing practices are emerging along with environmental sensing technologies. Through discussing specific instances where sensors are deployed for environmental study and citizen engagement across three areas of environmental sensing, from wild sensing to pollution sensing and urban sensing, Program Earth asks how sensor technologies are generating distinct ways of programming environments and environmental relations. What are the implications for wiring up environments in these ways? How do sensor applications not only program environments, but also program the sorts of citizens and collectives we might become? Working across digital media theory, science and technology studies, and environmental studies, Program Earth takes up these questions to examine the distinct environments, exchanges, and entities that take hold through these sensorized projects. This study develops the concept of the becoming environmental of computation in order to map the ways in which sensors are used to understand ecological processes, to track the migration of animals, to monitor pollutants, to facilitate urban participation, and to program infrastructure. Through these examples, Program Earth suggests that the programming of Earth yields processes for making new environments not necessarily as an extension of humans, but rather as new “techno-geographies” that emerge across technologies, people, practices, and more-than-human entities.

Environments are increasingly becoming technologized sites of data production. From smart cities to smart forests, digital networks are analyzing and joining up environmental processes. This commentary focuses on one such understudied smart environment, smart forests, as emerging digital infrastructures that are materializing to manage and mitigate environmental change. How does the digitalization of forests not only change understandings of these environments but also generate different practices and ontologies for addressing environmental change? I first analyze smart forests within the expanding area of smart environments, and then discuss five digital practices that characterize smart forests. Based on this analysis, I suggest that forests are not only becoming highly digital environments but also that forests are transforming into technologies for managing environmental change. Smart forest interventions therefore expand the scope of what could count as a technology, especially in the context of data-oriented planetary governance.

Citizen sensing, or the use of low-cost and accessible digital technologies to monitor environments, has contributed to new types of environmental data and data practices. Through a discussion of participatory research into air pollution sensing with residents of northeastern Pennsylvania concerned about the effects of hydraulic fracturing, we examine how new technologies for generating environmental data also give rise to new problems for analysing and making sense of citizen-gathered data. After first outlining the citizen data practices we collaboratively developed with residents for monitoring air quality, we then describe the data stories that we created along with citizens as a method and technique for composing data. We further mobilise the concept of ‘just good enough data’ to discuss the ways in which citizen data gives rise to alternative ways of creating, valuing and interpreting datasets. We specifically consider how environmental data raises different concerns and possibilities in relation to Big Data, which can be distinct from security or social media studies. We then suggest ways in which citizen datasets could generate different practices and interpretive insights that go beyond the usual uses of environmental data for regulation, compliance and modelling to generate expanded data citizenships.

This is a study of the material life of information and its devices; of electronic waste in its physical and electronic incarnations; a cultural and material mapping of the spaces where electronics in the form of both hardware and information accumulate, break down, or are stowed away. Where other studies have addressed "digital" technology through a focus on its immateriality or virtual qualities, Gabrys traces the material, spatial, cultural and political infrastructures that enable the emergence and dissolution of these technologies. In the course of her book, she explores five interrelated "spaces" where electronics fall apart: from Silicon Valley to Nasdaq, from containers bound for China to museums and archives that preserve obsolete electronics as cultural artifacts, to the landfill as material repository.\ud \ud Digital Rubbish describes the materiality of electronics from a unique perspective, examining the multiple forms of waste that electronics create as evidence of the resources, labor, and imaginaries that are bundled into these machines. Ranging across studies of media and technology, as well as environments, geography, and design, Jennifer Gabrys draws together the far-reaching material and cultural processes that enable the making and breaking of these technologies
