Self-Organizing Special Districts: A Tool for Community Change and Development

Can self-organizing special districts created from the bottom up be a tool for community change and development? Focusing on community services districts in California, this study introduces the context in which communities opt out of a county service system to reshape their governing structure for better representation. The empirical part measures their effectiveness, using single-family home sale prices as an impact metric. Leveraging multi-level difference-in-difference hedonic regression methods, the analysis shows that district formation increases the prices annually up to 16 percent, compared to both the surrounding and distant county service areas, indicating their efficacy as a tool for community change and development.

Environmental Justice and Urban Parks. A Case Study Applied to Tarragona (Spain)

There is consensus regarding the fact that urban green areas contribute to the quality of life of their inhabitants. Therefore, efficient city management must assess whether the population has access to green areas and the areas’ quality in relation to, for example, vegetation, facilities or furnishings. Therefore, the objective is to establish environmental justice of urban parks in Tarragona (Spain) by developing a Park Quality Index (PQI) and the sociodemographic characteristics (level of studies, Human Development Index –HDI–, home sale and rental prices) of the population living within 300 m of a park. To prepare this, a GIS-integrated Multi-Criteria Evaluation (MCE) was produced. The results show that the green areas have low accessibility and availability and that most parks obtain an average-low PQI, with the best-valued aspect being the vegetation and the worst being the facilities. Regarding the degree of environmental justice, a causal relationship between the PQI and the indicators used emerges. The average value of the home sale prices is the one that shows the greatest correlation. These results can be used together with participatory procedures as a basis for identifying places with greater inequality, and for selecting the more effective actions that enable increasing environmental justice with respect to green areas.
