My research provides a convincing conceptualization of how a perceived increase in insecurity in aid provision is negotiated, structured and spatialized in international humanitarian organizations (IHOs). I trace empirically how security processes manifest spatially in the ICRC, MSF and CARE International in the context of Ethiopia, how manuals and protocols are negotiated and implemented in the three IHOs, and the effects this has on the presence and future of aid as both practice and concept.
