Global warming has been an important issue in the past few decades, with many influencing factors, and urbanization is one of the main factors. So how does it work?

Urban morphology, which is an embodiment of development densities, land uses, biomass index and building configurations among others affects urban air quality by attenuating wind circulation and generation of GHGs, consequently accentuating the concentration of air pollutants to heighten global warming and climate change.

Over the years, the ever-increasing urban population has been accommodated by urban expansion, but the expansion of built-up areas to natural vegetation has destroyed the ecology.Due to the high rate of urbanization in Nairobi, this phenomenon is well reflected here.

Maurice O Oyugi investigated the air quality in Nairobi, Kenya. Four air pollutants are considered: carbon dioxide, nitrogen dioxide, sulfur dioxide, and suspended particulate matter. In addition, the relationship between urban air quality and several morphological parameters (such as development density, biomass index, and land use) is also studied.

Maurice O Oyugi combined a large amount of data and pictures to clearly introduce his research. For details, please click:
