Cities as Complex Systems

Published July 28, 2021 Calls for Papers Collections

Cities are centres of human interactions and the innovations that arise from them. Urbanization has led to many positive developments for society, but also contributes to many of our most pressing challenges, from sustainability and climate change to poverty and inequality.

In this PLOS ONE collection, our expert guest editors have compiled a selection of complex systems and networks research that is applied to questions in urban science.
