In this paper we estimate the relationship between urban sprawl and a measure of air quality, namely the number of days in which the PM10 concentration exceeds safeguard limits in European Union cities. Building on a multidimensional representation of sprawl, the paper employs several indicators to account for built-up area development, population density, and residential discontinuity. The paper employs generalised additive models to disentangle the non-linear effects in the variables and the interaction effects of the three sprawl dimensions. A significant and robust effect of urban morphology emerges after controlling for socio-economic, demographic, and climatic factors and the geographical location of the city. We find that urban sprawl impacts positively on pollutant concentration, but the effect is highly context-specific because of threshold effects and interactions.

Bulu and Peterongan are traditional markets with a history related to Semarang City, Indonesia. They have both been transformed into new markets with better and more complete buildings and facilities. It was conducted by the government to realize the people’s market revitalization program and sustainable development goals (SDGs) because sustainability is very important for historical buildings. This however, has reduced their conservative buildings due to the reconstruction of the Bulu Market after a fire accident and almost 75% of the buildings in Peterongan Market. The development caused a reduction in the demand of traders to sell and customers to shop due to the discomfort provided by the post-revitalization buildings. Therefore, a qualitative method was applied in this study to explain the phenomenon and sustainability of the post-revitalization of these two markets, and the findings are expected to be used in forming the strategy to encourage the sustainability of these markets.
