The conference aims to explore the interdependence between the cities and their people, the mutual power they exercise upon each other, with cities absorbing individuals and humans conquering urban spaces. It will also focus on the various aspects that characterize the world’s capitals, conurbations and metropolitan regions, their strengths and achievements, challenges and opportunities, problems and solutions, as well as the realities of the 21st century that are placing increasing pressures upon both cities and their inhabitants: overpopulation, overconsumption, poverty, deforestation, pollution, climate change, etc. And last but not least the conference will investigate the heterogeneous nature and the romantic fascination exerted by urban areas.
