Following the implementation of the petrochemical industry, the population of Camp de Tarragona began living with a chemical risk, and after two consecutive years of chemical-related accidents with fatalities (in 2019 in the firm Carburos Metálicos, and in 2020 in the firm IQOXE), it is necessary to know the population’s perception of this activity. Therefore, this study aims to analyze the population’s risk perception regarding the petrochemical industry, by applying a Public Participation Geographic Information System (PPGIS). To this end, the risk perception data obtained from the PPGIS were correlated with the sociodemographic data from the surveys; an analysis was made of the perceived risks associated with this activity and what its possible effect would be on a territorial level, always from the point of view of the surveyed public. The results showed that the population clearly identifies on the map what the main sources of chemical risk are and which places would be affected by a possible explosion. In addition, it was verified that certain sociodemographic characteristics, such as gender or age, affect people’s perception of the risk, and that the weather conditions and anomalous situations within the industry also influence people’s perception, indicating high values of danger.

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.

Reducing urban environmental inequity is one of the main objectives in advancing towards more sustainable cities. This situation implies developing tools that allow for an integrated assessment environmental and social impacts, to reveal inequalities in the distribution of resources and environmental risks. Applying indicators by using Geographic Information Systems (GIS) and statistical tools can be a valid option for fulfilling this aim, since it allows for territorial patterns in disparities to be exposed. The aim of this work is to identify and classify the environmental equity indicators applied to date in studies that use statistical methods and GIS for processing and analysing them. Thus, a scoping review was conducted using the SALSA Framework and PRISMA extension for scoping reviews protocol based on the Scopus, Web of Science and Scielo databases. A total of 31 articles were identified that fulfilled the search criteria and which were developed mainly by countries in North American and Europe. They involved 167 different indicators that demonstrate the complexity and heterogeneity in addressing this topic. Negative aspects of the environment such as pollution, and social factors such as the socioeconomic status, were the most used.

La ciutat de Tarragona es caracteritza per ser un dels principals pols d’assentament de la població de nacionalitat marroquina a Catalunya. Des d’inicis del segle XXI, aquesta població ha protagonitzat un important creixement que la situa a la capçalera del rànquing de nacionalitats estrangeres del municipi. Paral·lelament a l’augment del nombre d’efectius, el col·lectiu ha experimentat canvis substancials en la seva distribució espacial. L’objectiu d’aquest treball és precisament analitzar l’evolució de les pautes d’assentament i els nivells de segregació residencial de la comunitat marroquina a l’interior de l’espai urbà tarragoní corresponents al període temporal 2004-2012 a partir de les dades del Padró Municipal d’habitants.

This research provides a comprehensive view of the geolocation of physical health assets in the city of Tarragona (Spain) and how these assets are used and recommended by healthcare professionals to promote healthy lifestyles. Focusing on the distribution and accessibility of sports facilities, such as outdoor gyms or football and basketball courts, this study highlights the importance of these assets in leading a healthy life and preventing chronic diseases. This article investigates the availability of these assets and their prescription by healthcare professionals to improve people’s quality of life through surveys and fieldwork. It evaluates both the knowledge healthcare professionals have about these available assets in the area and the types of physical activity they prescribe. The results show significant variability in the availability of physical health assets across different neighbourhoods. However, most residents have good walking access to these assets, especially in the central and western parts of the city. This study concludes that while physical health assets are an underutilised resource for healthcare professionals, enhancing the awareness and prescription of these assets could improve public health outcomes, particularly for older adults.

From an equity-centered perspective, urban and environmental processes that negatively impact specific groups while benefiting others are critical determinants of urban sustainability. These complex processes intertwine various analytical dimensions and may differ based on territorial context. Studies primarily conducted in the Global North have aimed to assess environmental equity in cities by developing intricate indices; however, achieving consensus on which variables and indicators to employ or how much weight to assign to each remains elusive. We aimed to identify suitable variables for measuring socio-environmental equity and proposed weighted criteria for evaluation in Ibero-American cities. To accomplish this, we surveyed 41 qualified informants, using a criteria weighting technique to assess the variables and establish their relative importance. We found that inequalities regarding access, quality of green and public spaces, and the impacts of environmental threats were the most recognized issues in the region, with individuals from lower socioeconomic strata being the most affected. Furthermore, we proposed and weighted 14 essential and supplementary variables to evaluate socio-environmental equity, including factors such as access to basic services, housing quality, water and air pollution, the presence of green spaces, extreme weather events, and their effects on public health.
