Megacities such as Santiago are becoming a worldwide phenomenon. In six of eleven South American countries, over 25 percent of the population lives in a single city. What policies should national governments adopt with regard to dominant metropolises? Is it appropriate to restrict the flow of population to big cities? Or should governments take a laissez-faire attitude and permit city growth?

Focusing on Chile, this book argues that appropriate government action lies between these extremes. The authors espouse spatial policies that mitigate the social costs of congestion and pollution but also ensure that migrants pay the social costs of moving to big cities.

The Role of Indigenous People in the Founding of America's First Major Border Towns
In 1811, while escorting members of John Jacob Astor’s Pacific Fur Company up the Columbia River, their Chinookan guide refused to advance beyond a particular point that marked a boundary between his people and another indigenous group. Long before European contact, Native Americans created and maintained recognized borders, ranging from family hunting and fishing properties to larger tribal territories to vast river valley regions. Within the confines of these respective borders, the native population often established permanent settlements that acted as the venues for the major political, economic, and social activities that took place in virtually every part of precolonial North America. It was the location of these native settlements that played a major role in the establishment of the first European, and later, American frontier towns.
In Settling the Frontier: Urban Development in America’s Borderlands, 1600–1830, historian Joseph P. Alessi examines how the Pecos, Mohawk, Ohioan, and Chinook tribal communities aided Europeans and Americans in the founding of five of America’s earliest border towns—Santa Fe (New Mexico), Fort Amsterdam (New York City), Fort Orange (Albany, New York), Fort Pitt (Pittsburgh, Pennsylvania), and Fort Astoria (Portland, Oregon). Filling a void in scholarship about the role of Native American communities in  the settlement of North America, Alessi reveals that, although often resistant to European and American progress or abused by it, Indians played an integral role in motivating and assisting Europeans with the establishment of frontier towns. In addition to the location of these towns, the native population was often crucial to the survival of the settlers in unfamiliar and unforgiving environments. As a result, these new towns became the logistical and economic vanguards for even greater development and exploitation of North America. 

This volume addresses the relationship between the UNESCO World Heritage Site of Angkor (Cambodia), and the nearby town of Siem Reap. While previous work on heritage sites has mainly focused on protected areas, this book shifts the attention to the margins, where detrimental, tourism-driven urban development may take place. By delimiting a protected site, a non-heritage space is created in which spatial fragmentation, disruptive development processes, and unjust power plays can occur. In post-war Cambodia, liberalization and collective aspirations for progress have provided a strong incentive for modernization. Controversial interests compete in the arena of urban development, and real estate development prevails over planned growth. At the same time, Siem Reap’s marginal position allows for some freedom in architectural and urban design. In the shadow of institutional control, this architectural space expresses alternative visions of the Khmer heritage and connects them with images of urban modernity.
