What we can and cannot learn from the history of world population.
Mankind is passing through an exceptional phase of accelerated population growth that generates anxiety about the future. How many billion people will share the limited resources of our globe a century from now? What will be the consequences of globalization for human behaviour? How will individuals react to emerging new constraints? What will be the consequences of climate change for human society? Obviously enough, history cannot offer operational answers to these crucial questions. Nevertheless, history offers some interesting insights into demographic behaviour experienced in the past that could be replicated in the future, with the variations and adaptations dictated by the changing contexts. In other words, there are constants and structures in human behaviour, and there are robust mechanisms in the functioning of demographic systems that are of some help in preparing us to deal with the future.
