Understanding spatial growth and resilience of megacities based on the DPSIR conceptual model : study case: Greater Cairo Metropolis, Egypt

Die Bewältigung stadtplanerischer Aufgaben in komplexen urbanen Systemen, wie des Großraums Kairo (GCM) bedarf eines vertieften Verständnisses dieses sozio-ökologischen Systems. In dieser Studie werden die Konzepte des räumlichen Wachstums und der räumlichen Resilienz genutzt, um über die Analyse de...
