A New Urban Landscape in East–Southeast Asia, 2000–2010

East–Southeast Asia is currently one of the fastest urbanizing regions in the world, with countries such as China climbing from 20 to 50% urbanized in just a few decades. By 2050, these countries are projected to add 1 billion people, with 90% of that growth occurring in cities. This population shif...

The patterns and rates of change uncovered by these data sets provide a unique record of the massive urban transition currently underway in East–Southeast Asia that is impacting local-regional climate, pollution levels, water quality/availability, arable land, as well as the livelihoods and vulnerability of populations in the region. 2015-12-01T21:45:15Z 2015-12-01T21:45:15Z 2015-03-03 Journal Article Environmental Research Letters http://hdl.handle.net/10986/23179 en_US CC BY 3.0 IGO http://creativecommons.org/licenses/by/3.0/igo World Bank IOP Publishing Publications & Research :: Journal Article Publications & Research East Asia Southeast Asia
