Air pollution, particularly PM2.5 particulate matter, is a significant issue in Santiago, the capital of Chile. Santiago’s pollution problem is exacerbated by its unique geographic location nestled against the Andes mountain range in the central valley of Chile. This paper uses network models that were developed primarily to analyze systemic risk in the financial system to identify those locations in the city that are most important for explaining PM2.5 levels.

Municipal solid waste management is a challenging issue in developing countries. An unclean neighborhood could have a significant negative impact on housing property values too as it may lead to numerous diseases in addition to diminished aesthetic value. This study examines the effects of municipal solid waste collection services at the neighborhood level on housing property values using the hedonic price model. We use a sub-sample of nationally representative household survey data from urban areas as well as primary data collected from one of the metropolitan cities in Nepal.

Despite the growing body of evidence showing benefits and values of recreational ecosystem services, in sub-Saharan Africa, such evidence is extremely limited. This is problematic, and may perhaps explain their current poor condition. This study uses a random survey of households residing in Dar es Salaam to value the benefits of urban parks. The estimation is based on random utility framework where different models, with varying assumptions on preference and scale heterogeneity, are estimated.

Executive Summary

Historically, transport infrastructure connecting the most agriculturally productive areas of Mozambique and the richer southern region has been poor. A primary bottleneck was an unreliable ferry service over the Zambezi river, addressed by construction of a road bridge in 2009. In this paper we identify the impact of this transport infrastructure enhancement on integration of national maize markets.
