:: The 4th Era ::

Urban ecology, environmental justice, gendered inequities, primate city politics, the struggle of growing megacities…it’s all here in this fantastic piece of investigative reporting.  The article highlights the ecological problems that Mexico City faces (high-altitude exacerbates air pollution, interior drainage worsens water pollution, limited aquifers that are overworked lead to subsidence, importing water outside of the basin requires enormous amounts of energy, etc.).  just because the article doesn't use the word 'geography' doesn't mean that it isn't incredibly geographic. All of these problems are at the heart of human-environmental nexus of 21st century urbanization.

Pearl river delta

Cities in this region have experienced spectacular growth; they are at the heart of China's manufacturing and exporting boom.  For example, Shenzen was a small city with about 10,000 residents in 1980 but is now a megacity with over 10 million people.  China's SEZs (Special Economic Zones).  Cities that were once separate entities have coalesced into a large conurbation and if they are counted as one, it's now the largest metropolitan area.  Cities like London and New York become global cities over hundreds of years--this happened in one generation.  Click here for 5 infographics showing East Asia's massive urban growth.
