Mexico City, Parched and Sinking, Faces a Water Crisis

Mexico City, Parched and Sinking, Faces a Water Crisis | :: The 4th Era :: | Scoop.it

"A host of environmental factors are threatening to push a crowded capital toward a breaking point."

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.

(Mexico/Central America) Mexico city seems to be built in the worst way possible. The original Aztec architects could not imagine the locational problems the city faces today. Originally built on an island, Spanish conquerors drained the lakes and created an inland, mountainous position that causes the city to sink inches every year. Ironically, the city is now forced to use underground water sources or expensively import drinking water and poor locals can rarely count on tap water. The uneven clay and volcanic soil foundation and climate change further drives subsidence of this unplanned metropolis. Climate change will also create a series of floods and droughts and the inefficient sewage and water system will lead to devastation.

The economic threat to cities isn't gentrification; it's the opposite

The economic threat to cities isn't gentrification; it's the opposite | :: The 4th Era :: | Scoop.it
Many urban neighborhoods are places of concentrated poverty, and it's killing opportunity in the US.


American cities are growing, and as they grow, they're adding lots of high-poverty neighborhoods. Nearly three times as many "high-poverty" census tracts existed in 2010 as in 1970.  That's unsettling on its face but even more so when you see the havoc a poor neighborhood can wreak on a resident's chances at a good life. Forget gentrification — this is a bigger problem. 


The chart above tallies up the people living in these neighborhoods in 1970 and 2010. What it shows is that the number of people living in high-poverty neighborhoods — those with poverty rates of 30 percent or more — has roughly doubled since 1970. That's because these neighborhoods of concentrated poverty have a tendency to stay that way, even while new ones sprout up.

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.
