The contemporary illusion : population growth and sustainability

Since the 1970s, debates on “population growth” and “sustainability” have fluctuated markedly between pessimistic forecasts and optimistic certainties. Nowadays, they have reached a strange, comfortable illusion according to which the demographic future of our planet does not seem to be a problem at all. Nevertheless, median population growth projections by 2100 indicate that an arrest of the increase by the end of the century is rather unlikely. The future prospect is made even more critical by the fact that the increase will occur in what can be called demographic “Growing spots,” strongly opposed to just as many “Aging spots.” In these terms, therefore, the future demographic dynamics will certainly pose a challenge to the “population growth-sustainability” combination, for which it will be necessary to develop a new paradigm capable of operating in a “strong transcalar perspective,” within a global space that will increasingly acquire characteristics of fluidity and changeability.
