Heritage Under Threat: The World's Oldest Cities

摘要

Historic preservation has been an integral part of planning since the 1920s. Most often the focus is on buildings or archaeological sites, and seldom do we consider an entire city worthy ofpreserva-tion. But what of the world's oldest cities? They represent a major evolution in human development and are the physical record of this remarkable step in building communities. We asked Geoff Emberling, an archaeologist of urban development, to tell us how upheavals are affecting the world's legacy of ancient cities.
