In recent years, it has become a commonplace to argue that cities should be the focus point of sustainable development. Various authors have presented a variety of arguments why cities should be the preferred target to foster sustainable development-focused innovation;
- The average consumption of resources of urban dwellers is higher.
- The population of cities is growing continuously, while rural populations stabilize.
- Deteriorating living conditions and segregation in cities caused by processes of gentrification of traditional neighbourhoods that drive out lower income groups to the suburbs.
- Cities are ‘concentrated’ emitters of pollutants and therefore solutions and re-use might be easier to implement.
