The Age of Sustainability: Just Transitions in a Complex World provides an interpretation of the global economic and ecological crisis from a distinct African perspective. Drawing on a relational epistemology and ontology that emerges from the intersection between contemporary Sub-Saharan African philosophy and western post-humanism, Swilling traverses a vast terrain in order to illustrate his argument that there are multiple transitions already underway at the global, national and local levels. He offers a theory of change that avoids the false promise of superficial reforms (‘greenwash’) and the grandiose claims about ‘structural change’. Instead, he proposes that we need to be radical incrementalists in the way we fuse together real-world experiments and the making of global futures. He argues that the directionality of the global energy transition will shape the way the global political economy evolves beyond the current crisis. The intellectual and operational bankruptcy of neo-liberal economics opens the way for alternative futures, but these alternatives have yet to consolidate themselves at the global and national levels. They are, however, emerging across all world regions at the local level. This is particularly true when it comes to the emerging commons-based peer-to-peer economies that we see at local and global levels. Unless we understand the complex dynamics of the deep transition already underway, and how this is shaping all our choices about governance, economics, well-being, urban living and cultural norms, we will be ill-equipped for the rapidly unfolding future that we all experience on a daily basis.
