In recent years, ecological issues have grown to become some of the most significant sociopolitical concerns of our time - something which has been reflected by an explosion in engagement with such issues across every area of arts and culture. Across most major art forms, this trend has been identified, analysed and promoted both by critical studies in the growing field of ecocriticism, and by the curatorial recognition of new 'ecological' genres; however, to date there has been no equivalent ecologically-focused engagement within sound art. This can be recognised as the product of two significant gaps in sound art scholarship: the first critical in nature, regarding the lack of ecocritical engagement with sound art; and the second curatorial, regarding the failure to recognise the growing number of ecologically-engaged works of sound art as a distinct genre in their own right. The research detailed within this thesis will address each of these gaps by conducting a comprehensive investigation into ecology and environmentalism in contemporary sound art. The critical gap will be tackled by coupling a thorough analysis of the field of ecocriticism with an investigation into the ways in which ecological principles manifest within sound as a medium and listening as a means of engagement. This will then be used to develop a new ecocritical framework specifically designed for sound art, which will be employed to conduct ecocritical listenings to a selection of canonical and contemporary sound works. To address the curatorial gap, meanwhile, a new genre of 'ecological sound art' will be proposed, with a second set of ecocritical listenings focused upon a selection of ecological sound works in order to determine the precise nature of their ecological engagement, and to develop both a comprehensive definition and an initial catalogue of works for this important and timely contemporary movement.

This research is a practice-based inquiry into the contribution of art to processes in which communities explore, design and proceed on sustainable ways forward. In rejecting an overly technocratic approach, this thesis follows a learning-based conception of sustainable development. Rather than transmitting predetermined solutions, social learning is about establishing a prolific framework of conditions in which people can explore for themselves what is ‘right’, sustainable and desired. Such learning shows important overlaps with art, in that it does not set out to transmit a predetermined message; instead the meaning of something is collectively made throughout the process. Where the shift from instrumental, technocratic approaches to participatory, intersubjective and open-ended approaches to sustainable development is relatively new in the social sciences, artists arguably have a longer legacy working in non-instrumental and ‘goal-searching’ ways. Subsequently, this thesis proposes a range of artful approaches that would allow educators to create spaces in which meaning is mutually created. These are the result of three research activities: the researcher interviewed artists, she participated in practices of artists, and reflected upon her own making process in which she conceived social learning as a contextual arts practice. Where this thesis takes social learning into new areas of knowledge is in the way that it conceives the meaning of sustainable development as continuously coming out of the present. Despite a professed action-oriented and experiential rendition of sustainable development, academics in the field of learning for sustainability present the concept as theoretical and abstract: it exists separated from the lived world of practice that it draws meaning from. This thesis argues that the key potential of art lies in counteracting such excessive objectification of socio-environmental issues. Through locative meaning-making, for example, meanings are derived from the here and now rather than from abstracted terms. Consequently, social learning should not strive for sustainable development as an objective, general goal in itself. Instead the learning should be conceived as an emergent process that is driven by an active vehicle, score or invitation that generates an interaction-rich environment in which meaning-making can happen. Sustainable development then threads through the fabric of whatever is happening, rather than being a focus on its own.

Personal space is a human’s imaginary system of precaution and an important concept for exploring territoriality, but between humans and technology because machinic agencies transfer, relocate, enact and reenact territorially. Literatures of territoriality, violence and affect are uniquely brought together, with chatbots as the research object to argue that their ongoing development as artificial agents, and the ambiguity of violence they can engender, have broader ramifications for a socio-technical research programme. These literatures help to understand the interrelation of virtual and actual spatiality relevant to research involving chatrooms and internet forums, automated systems and processes, as well as human and machine agencies; because all of these spaces, methods and agencies involve the personal sphere. The thesis is an ethical tale of cruel techno-science that is performed through conceptualisations from the creative arts, constituting a PhD by practice. This thesis chronicles four chatbots, taking into account interventions made in fine art, design, fiction and film that are omitted from a history of agent technology. The thesis re-interprets Edward Hall’s work on proxemics, personal space and territoriality, using techniques of the bricoleur and rudiments (an undeveloped and speculative method of practice), to understand chatbot techniques such as the pick-up, their entrapment logics, their repetitions of hateful speech, their nonsense talk (including how they disorientate spatial metaphors), as well as how developers switch on and off their learning functionality. Semi-structured interviews and online forum postings with chatbot developers were used to expand and reflect on the rudimentary method. To urge that this project is timely is itself a statement of anxiety. Chatbots can manipulate, exceed, and exhaust a human understanding of both space and time. Violence between humans and machines in online and offline spaces is explored as an interweaving of agency and spatiality. A series of rudiments were used to probe empirical experiments such as the Prisoner’s Dilemma (Tucker, 1950). The spatial metaphors of confinement as a parable of entrapment, are revealed within that logic and that of chatbots. The ‘Obedience to Authority’ experiments (Milgram, 1961) were used to reflect on the roles played by machines which are then reflected into a discussion of chatbots and the experiments done in and around them. The agency of the experimenter was revealed in the machine as evidenced with chatbots which has ethical ramifications. The argument of personal space is widened to include the ways machinic territoriality and its violence impacts on our ways of living together both in the private spheres of our computers and homes, as well as in state-regulated conditions (Directive-3, 2003). The misanthropic aspects of chatbot design are reflected through the methodology of designing out of fear. I argue that personal spaces create misanthropic design imperatives, methods and ways of living. Furthermore, the technological agencies of personal spaces have a confining impact on the transient spaces of the non-places in a wider discussion of the lift, chatroom and car. The violent origins of the chatbot are linked to various imaginings of impending disaster through visualisations, supported by case studies in fiction to look at the resonance of how anxiety transformed into terror when considering the affects of violence.
