Calls for a greater inclusion of local actors have featured for some time in debates on how to make humanitarian action more efficient and address unequal power relations within the humanitarian system. Though the localisation agenda is at the core of current reform efforts in the humanitarian sector, the debate lacks a critical discussion of underlying assumptions - most strikingly, the very conceptualisation of the local itself. It is argued that the current discourse is dominated by a problematic conceptualisation of the local in binary opposition to the international, leading to blind spots in the analysis of exclusionary practices of the humanitarian sector. As such the localisation agenda risks perpetuating the very issues it wants to redress. A critical localism is thus proposed as a framework for much needed research on the localisation agenda.
