Parque Científico y Tecnológico (PACYT, Science and Technology Park) is a large-scale R+D project that seems to be framed in a Smart City plan for Concepción, Chile, which the media has presented as “the Chilean Silicon Valley” (Araus, 2015; Tele13, 2019) and promises to bring not only research and development opportunities for the city but also thousands of direct and indirect jobs (Estudio Interdiseño, 2018; la Tercera, 2015) carried out by PACYT Corporation. Nonetheless, voices have raised to question the construction of the 91 hectares initiative, and some of them have even organized in citizen groups targeting the creation of the urban complex, which actively share information contesting the PACYT through social media, and coordinate activities to protest and spread the word. This is the study case to be analyzed in the present research, which aims to explore and understand, on the one hand, the reasons that have led to the organization of citizens contesting the PACYT project, and on the other hand, the way the project has been advertised and developed in relationship to the city's inhabitants. It intends to make a novel contribution to the field of Urban Studies, both in the areas of Critical Smart Urbanism and Postcolonial Studies, which in this case collide in Latin America, part of the Global South, while opening a discussion around the topic of citizens contesting urban developments with a Smart City background, where few incursions have been made and more specifically in the Latin American context, where the Smart City seems to have a particular interpretation. With that in mind, the current research tries to dig into an under-studied territory, and in doing so, it plans to bring to the table the relevance of studying the approach and way of developing Smart Cities’ ideas in Latin American, and to put focus on what city’s inhabitants have to say about those developments and what their interests are, using the lenses of the right to the city and the understandings coming from urban social movements and conflicts. In that sense, the research outputs are to question the form in which Smart City projects are being implemented in Latin America and to find possible guidelines to incorporate the city’s inhabitants in the development of them elsewhere, with that in mind, future research can be supported by this investigation, which encourages further studies both in the described fields and territory. To do so, the current investigation explores and unwrap theories regarding the mentioned fields and focuses on analyzing the case making use of mixed methods research, by executing qualitative and quantitative methodological tools to reach relevant data that helps to answer the research inquiries. In that sense, the results show that it can be confirmed that the nature of the PACYT, i.e. its R+D purposes and origins linked to a Smart City plan to transform the city into smartness, does not play a relevant role in the development of the conflict that has emerged between the PACYT management, and the people opposed to its construction, but several aspects explain the urban social conflict and that will be explored in the present work. / <p><strong>Acknowledgment.</strong></p><p>First of all, I would like to thank all the interviewees that decided to share their thoughts in the present study, as well as to all the people that participated in the survey; without your contribution, it would have not been possible for me to reach my research goals and to count on with the rich material I have. On the other hand, I want to thank people from academia, such as my peers, who have given me advice and stamina, to my tutor, who has contributed with his wisdom, and to my mentor at university, who has kept me on track and provided me with valuable insights. I am grateful to these people for helping me with my willpower and effectiveness. Finally, I need to thank those surrounding me, like my family for supporting me from the distance, my partner for being here to contain and take care of me, and my dog for always being around me and spreading his love and joy.</p>

Originating from a disenfranchisement with the contemporary definition and realisation of Westernised architecture as a commodity and product, this thesis seeks to explore alternative examples of positive socio-spatial practice and agency. These alternative spatial practices and methodologies are drawn from participatory and grass-roots development agency in informal settlements and contexts of economic absence, most notably in the global South. This thesis explores whether such examples can be interpreted as practical realisations of key theoretical advocacies for positive social space that have emerged in the context of post-Second World-War capitalism. The principal methodological framework utilises two differing trajectories of spatial discourse. Firstly, Henri Lefebvre and Doreen Massey as formative protagonists of Western spatial critique, and secondly, John F. C. Turner and Nabeel Hamdi as key advocates of participatory development practice in informal settlements. These two research trajectories are notably separated by geographical, economic and political differentiations, as well as conventional disciplinary boundaries. However by undertaking a close textual reading of these discourses this thesis critically re-contextualises the socio-spatial methodologies of participatory development practice, observing multiple theoretical convergences and provocative commonalities. This research proposes that by critically comparing these previously unconnected disciplinary trajectories certain similarities, resonances and equivalences become apparent. These resonances reveal comparable critiques of choice, value, and identity which transcend the gap between such differing theoretical and practical engagements with space. Subsequently, these thematic resonances allow this research to critically engage with further appropriate surrounding discourses, including Marxist theory, orientalism, post- structural pluralism, development anthropology, post-colonial theory and subaltern theory. 5 In summary, this thesis explores aspects of Henri Lefebvre's and Doreen Massey's urban and spatial theory through a close textual reading of key texts from their respective discourses. This methodology provides a layered analysis of post-Marxist urban space, and an exploration of an explicit connection between Lefebvre and Massey in terms of the social production and multiplicity of space. Subsequently, this examination provides a theoretical framework from which to reinterpret and revalue the approaches to participatory development practice found in the writings and projects of John Turner and Nabeel Hamdi. The resulting comparative framework generates interconnected thematic trajectories of enquiry that facilitate the re-reading and critical reflection of Turner and Hamdi's development practices. Thus, selected Western spatial discourse acts as a critical lens through which to re-value the social, political and economical achievements of participatory development. Reciprocally, development practice methodologies are recognised as invaluable and provocative realisations of the socio-spatial qualities that Western spatial discourse has long advocated for, and yet have remained predominantly unrealised in the global North.
