AbstractLiterature in Human Geography has given much attention to “encounters” and their impact on negotiating difference in everyday life. These studies, however, have focused solely on cities, while “other” spaces like refugee camps have received little attention to date. In this paper, I highlight the significance of “encounters” in camps by exposing three main types: the “refugee-refugee,” the “refugee-humanitarian,” and the “refugee-more-than-human” encounters. Using empirical examples from Zaatari camp in Jordan, I show that the “refugee-refugee” encounters cannot be fully understood without taking refugees’ culture, background, and urban identities into consideration. I also explain how the “refugee-humanitarian” encounters result in new types of behaviors and might harden the boundaries between both groups. And lastly, I demonstrate how the “refugee-more-than-human” encounters can inform us about refugees’ unique experiences with shelters, space, and materiality. Building on the examples given for each type, this article suggests that “encounters” have the ability to generate knowledge and learnings, which contributes to shaping the space of the camp by either enforcing boundaries between different groups and/or by allowing new and hybrid spatialities to emerge. This not only confirms that “encounters” are an important entry point in understanding the socio-spatial and material composition of refugee camps, but also that further studies in this regard are direly needed. It also suggests that architects and planners need to allow for the “new” to emerge as a result of these encounters and, therefore, to enable flexibility and adaptability within camps’ design and planning.

Colonial Warfare

Images of police armored vehicles in Ferguson and Baltimore have been influential in a public conversation about the militarization of the police. However, recent critical and abolitionist work on policing rejects the concept of “militarization” for obscuring the longstanding histories and institutional connections between military and police apparatuses. By following the transfers of armored vehicles to police, this article illuminates the logistical pathways that connect colonial warfare and domestic policing, adding an account of the material composition of police power to the historical work of critical and abolitionist thinkers. The article proceeds through a critical reading of records of the Defense Logistics Agency, tracking the transfer of surplus armored vehicles to the police. Designated as “high-visibility property” by the Defense Logistics Agency, these vehicles testify to the materiality of police power. The article then tracks the visibility and materiality of these vehicles as they are deployed in urban and suburban spaces and considers their unique capacity to suppress the democratic energies of crowds. Tracking the armored vehicle provides a way to ask how the rigid lines of fortified urban space are organized into mobile vectors and where ongoing processes of colonization enter these spatial processes.
