The 25 million residents of the world’s fourth largest city (urban area) can rest a bit easier, as the Taal volcano has become less threatening in the last few days. But there is still severe disruption, especially for the many people who have been forced to evacuate.

This article includes a brief description of the developments since the January 20 eruption and compares Manila to other major metropolitan areas also threatened by dangerous volcanoes (Seattle and Naples).  read more »

A long succession of urban theorists, including Jane Jacobs, have intuited, implied, or proclaimed the “organic” nature of cities. This organic concept of cities describes them as self-organizing, complex systems that might appear messy, but that disorderliness belies a deep structure governed by fundamentally rule-bound processes.  read more »

Earlier in this decade, cities—the bigger and denser the better—appeared as the planet’s geographic stars.  read more »

The strange but true geography of the Pacific Ocean has the Tokyo and Honolulu metropolitan areas outer island exurbs more than a thousand miles (1,600 kilometers) away from their urban cores, and a distance between the westernmost and easternmost points in Alaska of more than 2,000 miles (3,200 km), most of it open ocean waters and overlapping most easterly points in the United States.  read more »

Much of the media has been fascinated by the growing number of megacities (built up urban areas with at least 10 million residents). Not only are megacities regularly covered but various reports have them becoming denser. They’re not, as has been demonstrated by Professor Shlomo Angel, who leads the Urban Expansion Program at New York University’s Marron Institute.  read more »

Is America’s free market system working as advertised? Mostly yes, but it depends to a surprising degree on where you live.

Gov. Gavin Newsom has committed himself to look for ways of “unlocking the enormous potential” of the Central Valley, but in reality he seems more interested in slamming the door to its prosperity behind him.

In two critical moves the former San Francisco mayor has shown his incomprehension of how to address the needs of the vast California interior, particularly the over 6.5 million people in the 17 counties of the Central Valley.  read more »

With a new round of state and local elections just around the corner, I am regularly asked about what brings Americans out to the polls and helps them politically engage them with their communities.  read more »

This decade has witnessed an unprecedented expansion of the Greater San Francisco Bay Area (the San Jose-San Francisco combined statistical area or CSA), with the addition of three Central Valley metropolitan areas, Stockton, Modesto and Merced. Over the same period, there has been both a drop in the population growth rate and a shift of growth to the Central Valley exurban metropolitan areas.  read more »

Recent research sheds new light on the critical issue of the link between car travel and urban density. Conventional planning wisdom has it that increasing development density bestows benefits, most importantly that of reducing driving. This effect seems almost self-evident: more compaction, shorter distances, lower VMTs. Peter Newman and Jeffrey Kenworthy’s (1989) Cities and Automobile Dependence reinforced this intuitive assumption with their extensive and in-depth study (1986) which effectively sealed the case for thirty years.  read more »
