‘The paper of Feng et al. entitled ‘LA Megacity: a high-resolution land-atmosphere modelling system for urban CO2 emissions’ compares different model resolutions and emission maps to identify optimal configurations for simulating CO2 fields over a megacity. Although this concept of comparing different models or model configurations is not new, urban air quality poses some additional challenges ...

Megacity growth in the developing world is fueled by a desire to access their large local labor markets. Growing megacities suffer from high levels of traffic congestion and pollution, which degrade local quality of life. Transportation technology that allows individuals to access the megacity without living within its boundaries offers potentially large social benefits, because individuals can...

Seven-year measurements of precipitation, lightning flashes, and visibility from 2000 to 2006 have been analyzed in the Pearl River Delta (PRD) region, China, with a focus on the Guangzhou megacity area. Statistical analysis shows that the occurrence of heavy rainfall (>25 mm per day) and frequency of lightning strikes are reversely correlated to visibility during this period. To elucidate the ...

In the aftermath of the 9/11 disaster, Mayor Bloomberg of New York City unveiled an aggressive budget plan that included the temporary suspension of glass and plastics recycling. This was considered by many to be anti-environmental, but the results of this study show that for lack of markets, even at zero or negative prices, nearly 90% of the plastic and glass set aside by thoughtful New Yorker...

This article is an intervention in the epistemologies and methodologies of urban studies. It seeks to understand and transform the ways in which the cities of the global South are studied and represented in urban research, and to some extent in popular discourse. As such, the article is primarily concerned with a formation of ideas - "subaltern urbanism" - which undertakes the theorization of t...

This paper deals with the problem of locating new post offices in a megacity. To do so, a combination of geographical information system (GIS) and fuzzy goal programming (FGP) is used. In order to locate new offices, first six types of service facilities with high levels of interactions with post offices are defined. Then, aspiration level of proximity for each service facility is determined. B...
