Urban Challenges and Global Migration Patterns

Urban Challenges and City Organization

Theme 6: Problems of Big Cities

The organization of urban space and traffic, cities with supplies of water and food, environmental problems (atmospheric pollution), collection and treatment of refuse, and urban marginality, violence, housing, and equipment.

Causes and Consequences of Migration

Causes related to the place of origin: In these cases, we can mention demographic pressure, economic reasons, political and religious reasons, and other factors.

Causes related to the place of destination: These are related to the expectations of a decent life in places that offer the possibility of a better future.

Consequences of Migration

• Demographic: Young people are the most affected and they migrate to find a better place; in this respect, the host areas undergo a process of population rejuvenation.
• Economic: The economic aspects of migration are extensive.
• Cultural and Social: Migration has a strong impact on family structures. Host countries mirror cultural, linguistic, and religious identity; the adaptation to a new country is very complex, and immigrants often accept specific labor terms.
