The Handbook on Governmentality discusses the development of an interdisciplinary field of research, focusing on Michel Foucault's post-foundationalist concept of governmentality and the ways it has been used to write genealogies of modern states, the governance of societal problems and the governance of the self.Bringing together an international group of contributors, the Handbook examines major developments in debates on governmentality, as well as encouraging further research in areas such as climate change, decolonial politics, logistics, and populism. Chapters explore how governmentality reshapes policy analysis as political practice, the relationship between Foucault's ideas of government and postcolonial experiences, and how governmentality can illuminate discourse on the green economy and biopolitics. Analysing how contemporary socio-political issues including feminist politics, migration, and racialized medicine are interwoven with the concept of governmentality, this Handbook sheds light on the modern-day uses of Foucault's work.Providing a comprehensive overview of research on governmentality, this Handbook will be essential reading for students and scholars of development studies, geopolitics, political economy, organizational studies, political geography, postcolonial theory, and public policy. It will also be a key resource for policy makers in the field looking for a deeper theoretical understanding of the topic.
