Thomas Kolnberger, born in Salzburg, Austria, is PhD-candidate in Historical Geography at the University of Luxembourg (Laboratoire d’histoire) and Passau (Southeast Asian Studies, Germany). His lecture will highlight the on-going production of spatial relations between "planning from above" and "from below" as grass-rooted urban planning by looking back from Phnom Penh's "now" (after the fall of the Khmer Rouge-regime) to "then" (colonial times).
