Mid-sized City

Abstract
The urban argument currently assumes an extreme level of relevance for
governments and the society in general, due to the exponential increase of people
living in cities and the consequent associated degradation of quality of life.
Growth is continuously applying pressures over resources, infrastructures and
facilities, affecting negatively the standard of living in cities. In this context,
evaluating and monitoring the urban environmental quality has become a main
issue, particularly important when considered as a decision-support tool that
contributes to more liveable and sustainable cities. Viana do Castelo is a
mid-sized city located on the northwest seaside, which undertook the challenge
of developing an environmental program leading to the integration in a Healthy
Cities European Network. The identification of urban air quality levels and
people exposure was considered a priority in this program. The scientific toolbox
adopted to develop the studies includes air quality simulation models and a GIS
platform. Based on traffic and site physical characteristics, air pollution maps
were created and overlaid together with the land-use and population distribution
layers. This combination was the basis for the identification of critical zones,
both in terms of air quality levels and people exposure to this kind of pollution.
Furthermore, the results were used to sort out mitigation measures and priorities,
particularly important in a context of limited resources. This paper aims to
present the approach, including the theoretical framework, and to discuss the
results and their role within the city’s quality of life argument.
Keywords: urban air pollution, air pollution modelling.
