My research is on issues of urban sprawl and particularly focused on the nature, importance and implications of undeveloped areas and open tracts in between developments – named here as interstitial spaces – that determine the fragmented condition of suburban landscapes in an interspersed coexistence with built-up areas. Along with the critical idea that the debate about sprawl has been mainly focused on the ‘built-up realm’, this research highlights the presence of the in-between landscape defined by several unbuilt (or less developed) areas left into the expansion as somehow random outcomes – other less controlled processes in planning – that emerge as a parallel geography within the suburban space: pieces of countryside, geographical restrictions, brownfields, landfills, farmlands, forest lands, green corridors, abandoned lands, public spaces, military facilities, speculative areas and others, all as components of an interstitial landscape made by apparently inert spaces included into the urban fabric but paradoxically excluded from planning politics.
So, what are these interstitial spaces? How are they? How these spaces have been produced? What is their importance and contributions for the suburban performance? What are their implications in planning? For answering these questions, the research tries to match the literature about urban sprawl – or the production of the suburban built-up space – with the nature of the unbuilt landscape that collates issues of political ecology, ecosystem services, green infrastructure, urban agriculture, natural capital and regional policy. Some advance in defining the unbuilt landscape has been done, but not necessarily posited as a dimension of urban sprawl and the environmental improvement of suburban areas. Nevertheless, useful terms for this debate are the ‘in-between spaces’ (Sieverts, 2003; 2011), ‘vacant lands’ (Northam, 1971; Foo et al., 2013), ‘undeveloped lands’ (Zhang et al. 2012), ‘open tracts’ (Gillham, 2002), ‘non-places’ (Auge, 1995), ‘terrain vague’ (De Solá-Morales, 2002; Mariani and Barron, 2014), ‘interfragmentary spaces’ (Vidal, 2002), ‘non-urbanized areas’ (La Rosa and Privitera, 2013; La Greca, et al, 2011), ‘Wildspaces’ (Jorgensen and Keenan, 2012), ‘wastelands’ (Gandy, 2013) and hardly used, the terms ‘urban interstices’ (Jorgensen and Tylecote, 2007; Mubi, 2013) and ‘interstitial landscapes’(Gandy, 2011; Sousa Matus, 2014), which are adopted in this research to refer to this less addressed dimension of sprawl and as one that requires closer inspection.
Thereby, this research aims to analyse the interstitial landscape using as case study the capital city of Chile, Santiago, which illustrates a traditional sprawling expansion mainly driven by the housing debate. The aim is to determine to what extent the interstitial landscape is another component of the (post)suburban expansion and what is the role of this alternative geography of the unbuilt space in the performance of current city-regions.
I received a degree in Architecture in 2000 and an MSc in Architecture in 2006 at P. Universidad Católica de Chile. I am currently a PhD in Urban Studies (2012-2016) at The Bartlett School of Planning, UCL, London, UK.
I have been in academia from 2001, working as Lecturer in Architecture and Urban Design (Universidad de Los Lagos, Chile, 2000-2010, Universidad Tecnológica Metropolitana, UTEM, Chile, 2011-2012), as researcher at the Centre for Regional Studies and Local Development, CEDER (Universidad de Los Lagos, Chile, 2008-2009) and as Director of the Department of Architecture and Design at Universidad de Los Lagos, Chile (2006-2009). I have presented and published outcomes of my academic activities in Latin America and Europe aimed to academic, professional and non-expert audiences through conference presentations, peer review papers and public reports. From 2003 I have been permanently working as private consultant in Architecture and Planning for the indigenous community of San Juan de Costa, Chile.
My current research interests are centred on explorations of contemporary patterns of urban growth and change, urban fragmentation, scattered development including issues of metropolitan and regional development, all focused on the role and implications of undeveloped areas and open tracts as a way of providing a more comprehensive framework for the understanding of the urban sprawl phenomenon itself.
My PhD research is sponsored by the National Commission of Science and Technology, CONICYT, Chile, and The Bartlett School of Planning, UCL. The research is mainly focused on the presence and implications of undeveloped lands and open tracts in contemporary processes of (post)suburban growth.
