Considering alternatives to megaprojects for a sustainable future with degrowth principles

• Despite our current climate challenge and natural resources depletion, megaprojects’ megalomania is on the rise. • ‘Sustainability without megaprojects’ is suggested, using a critical perspective and mobilizing the literature on degrowth. • Degrowth principles of producing less, sharing more and deciding together should orient future research, practice and policy responses. Given the increasing scholarly attention to megaprojects and sustainability, this essay proposes an alternative to building bigger and more megaprojects. Using a critical perspective and mobilizing the literature on degrowth, it is suggested that scaling down could be beneficial on many levels. Megaprojects are ubiquitous, yet they have profound repercussions on the land and resources and on local communities, not always for the better. Suggesting the avenue of ‘sustainability without megaprojects’, some research streams are suggested to pursue this reflection in line with degrowth principles of producing less, sharing more and deciding together. While more research is necessary to understand more thoroughly the implications of degrowth principles to megaprojects framing, there is also a crucial need for political action to debate the alternatives and develop appropriate policy responses.
