Victoria Habermehl recently presented at The New Urban Ruins: Vacancy and the Post-Crisis City workshop at Trinity College Dublin. She presented on research in Argentina, focusing on bottom up responses to urban abandonment. Her paper was titled ‘Resisting organised abandonment, everyday socio-spatial practices in Mercado Bonpland, Buenos Aires’. This international workshop brought together researchers interested in rethinking austerity, vacancy, temporality and memory in cities. Specific cases drew out the regional examples and national contexts and led to a greater shared learning and understanding of how to analyse vacancy in the post crisis city more generally. In particular the Irish context of the Celtic Tiger period and subsequent crisis was central to intellectual debate. The discussions support our work within the co-producing urbanisms theme and is of particular relevance to our ESRC Knowledge Matters Project in helping us rethink the context of development in Greater Manchester.
