Post-growth is an overarching approach to global futures that looks to proactively respond to the limits-to-growth dilemma – the fact that, on a planet of finite resources, economies and populations cannot grow infinitely.
The term “post-growth” acknowledges that economic growth can generate beneficial effects up to a point but beyond that point (cited as $25,000 GDP/capita by Richard Wilkinson and Kate Pickett in their book, The Spirit Level) it is necessary to look for other indicators and techniques to increase wellbeing.
Post-growth can be distinguished from similar movements (such as degrowth and steady state economics) in that it seeks to identify and build on what's already working, rather than focusing on what is not.
Post-growth advocates try to encourage, connect and further develop already existing ideas, concepts, technologies, systems, initiatives, and actions. In this way, "post-growth" does not specify the answer to the limits-to-growth challenge, as "steady state economics" and "degrowth" do, but rather seeks to understand and address this challenge from a complex systems perspective that is constantly evolving. With this holistic complex systems approach, post-growth deals with all aspects of self and society (such as psychology, human nature, human evolution, cultures, social systems and economies) and the interrelation of all of these aspects. Accordingly, the post-growth concept also advocates solutions that are appropriate with regards to place, time, resource and cultural factors. Therefore, post-growth initiatives take shape in very different ways under different circumstances.
Post-growth can be considered an asset-based approach to community development – applied not only to community development but across a wide range of categories – in response to limits-to-growth challenges as it seeks to identify and build on cultural and technological assets to facilitate the emergence of post-growth futures.
