Abstract
The World Health Organization estimates that urban air pollution is one of the top 15 causes of death globally (one of the top 10 causes in high-income countries), responsible for ~ 1.7% of deaths annual (high-income countries, 2.1%).?How can we reduce those health effects? This presentation will discuss three investigations into that question. (1) Urban form describes the physical layout of an urban area ? for example, city shape, population density, and ?patchiness? of urban growth. We have found that air pollution is related to urban form, for cities in the US and internationally, raising the question of whether urban planning can help cities meet air quality goals. (2) In low-income countries, indoor air can be especially polluted, owing to combustion of solid fuels for heating and cooking. In a rural village in Karnataka, India, we conducted a randomized control trial of a higher-efficiency stove, to test whether the stove improves indoor air pollution, health effects, and climate-relevant emissions. (3) Prior research emphasizes the health benefits of active travel (walking, biking). Can urban planning increase active travel without worsening exposure to air pollution? We explore spatial patterns in risks from those two factors (physical inactivity; and exposure to air pollution). A constant theme through these topics is environmental justice: which groups have higher exposures to air pollution, and how exposure correlates with demographic attributes such as race and income.
