Our close colleague and collaborator, Professor Alvaro Sevilla-Buitrago of the Technical University of Madrid, who contributed a key chapter to Implosions/Explosions, has recently published a new article in Antipode that takes those arguments a step further.  Here, he offers further theoretical reflections on the variegated spatialities of “enclosure” under modern capitalism.  We look forward to further dialogues with Prof. Sevilla-Buitrago regarding the intimate connections between enclosure and urbanization. We are grateful for his permission to post the article here.
