Building cities resilience to climate change

Posted by Olive Heffernan on behalf on Paty Romero Lankao For the first time in human history, in this year half of the world’s population lives in urban regions. This proportion is expected to go up to more than 60 percent by 2030. In an effort to understand the urban vulnerabilities to climate change, and to highlight innovative solutions to increase cities resilience, the Rockefeller Foundation, along with the Center for Sustainable Urban Development (CSUD), of The Earth Institute at Columbia University, is sponsoring a week-long discussion (July 8-13) on “Building for climate change resilience” within of month-long series of  … Read more

Posted by Olive Heffernan on behalf of Paty Romero Lankao It does make sense to compare the per capita CO2 emissions of Mexico City and Los Angeles (see figure below) to illuminate the debate on shared but differentiated responsibilities on greenhouse gases emissions and show that just as urban centers register different levels and paths of economic development, cities do not contribute at the same level to global warming. For instance, the real GDP per capita of Los Angeles (US$40,031) is almost 3 times that of Mexico City (US$13,470). The paradox here is that many of those urban centers with  … Read more

Regarding mitigation, a high proportion of energy, industrial and transportation emissions is generated by urban areas. Although most of the electricity and fuels are produced outside cities, they are aimed at satisfying cities’ “thirst” of energy. Therefore, urban areas place a huge burden not only on the absorptive capacity of the local environment; they also influence wide patterns of energy and land use in the surrounding and more distant areas, in the livelihoods and quality of life of people living  … Read more
