Localization has been one of the buzzwords of the sector ever since it emerged from the World Humanitarian Summit in 2016. Since then, the word has become so widespread that it is hard to keep track of all the working groups, initiatives and commitments around localization. Like it or loathe it, the term is now part of the mainstream conversation within the international humanitarian and development sector. In recent years it has been joined by other phrases, most notably “decolonizing aid” and shifting power to local communities, the latter very much inspired by #ShiftThePower campaign started by Global Fund for Community Foundations (GFCF) in 2016. In some cases, webinars have been held and reports produced in which all three terms are used interchangeably, which raises two important questions. First, how do we differentiate the terms we are using? Do they really mean the same thing? Second, are these conversations about localization, shifting power and decolonizing a passing fad, something that will evaporate as quickly as it has emerged? Or is this a genuine trend towards a different way of thinking, working and seeing the world?
