Accommodation is one of the main sectors affected by the emergence of platform economies. This issue has been addressed by many researchers, but they have mainly focussed on Airbnb and large cities. Thus, there is a need for research on medium-sized cities and how they have been affected by the growth of short-term rental (STR) homes. Using official data, we analysed the spatial distribution of holiday rental homes in four Andalusian cities: Cordova, Granada, Malaga, and Seville. Using tourist density and intensity indicators, we created maps showing the concentration of STRs in historic centres, which matches the spatial distribution pattern of traditional tourist accommodation (TA). The analysis also identified areas in each city into which STRs may expand in the future. The results of this study may help policymakers and institutions responsible for territorial and tourism planning to better understand how the emergence of platform economies is impacting tourist destinations. They should also assist policymakers in making informed decisions on regulating this phenomenon.

La ciudad de Málaga ha ido orientando su modelo productivo hacia el turismo durante algo más de un siglo. La remodelación del centro histórico y la creciente especialización de parte de la ciudad en los servicios vinculados al turismo han generado una serie de externalidades negativas en la habitabilidad y la identidad de determinados espacios urbanos de la ciudad. Por ello, el presente estudio tiene como objetivo principal elaborar una metodología que permita medir por separado la distribución espacial e intensidad de los procesos de gentrificación y turistificación, para trasladarlo finalmente a una cartografía que integre ambos fenómenos urbanos, considerando la evolución temporal en muchas de las variables. Los resultados permiten identificar dónde se solapan ambos procesos y, además, posibilita el diagnóstico de su evolución espacial. La metodología permite concluir que ha habido un proceso de gentrificación y turistificación intensos en el centro de Málaga, con una expansión de forma continua hacia los principales ejes viarios y el litoral, distinguiéndose una mayor prevalencia de la turistificación en las coronas que rodean al centro histórico y un proceso de gentrificación en núcleos con un carácter arquitectónico particular.

The concept of neighborhood contagion focus is defined and justified as a basic spatial unit for epidemiological diagnosis and action, and a specific methodological procedure is provided to detect and map focuses and micro-focuses of contagion without using regular or artificial spatial units. The starting hypothesis is that the contagion in urban spaces manifests unevenly in the form of clusters of cases that are generated and developed by neighborhood contagion. Methodologically, the spatial distribution of those infected in the study area, the city of Málaga (Spain), is firstly analyzed from the disaggregated and anonymous address information. After defining the concept of neighborhood contagion focus and justifying its morphological parameters, a method to detect and map neighborhood contagion focus in urban settings is proposed and applied to the study case. As the main results, the existence of focuses and micro-focuses in the spatial pattern of contagion is verified. Focuses are considered as an ideal spatial analysis unit, and the advantages and potentialities of the use of mapping focus as a useful tool for health and territorial management in different phases of the epidemic are shown.

The assessment of vulnerability to the danger of flooding, with a focus on the need for rescue and assistance from the population, is still in an exploratory scientific phase. The main objective of this research is to propose a methodology based on the issues of rescue and assistance in the face of the risk of floods and to provide a tool for its management. A series of maps is presented, indicating those territorial elements that require rescue and surveillance in a prioritized manner in a visual and accessible way for public administration. Four methodological cartographic proposals have been designed as follows: (1) a map of territory sectors with special rescue needs (dependent population and/or buildings without shelter); a map of the impact on transportation infrastructure and vulnerable areas of buildings (2); a map of vulnerability to possible disorder and looting caused by flooding events (3); and a map of the increase in the cost of deployment for rescue and assistance systems (4). As an experimental zone to test the effectiveness of these proposals, a peri-urban area of the municipality of Málaga (Spain) is chosen, which has an extensive history of severe floods. The results confirm the applied and preventive nature of the tool, which can be incorporated into flood risk management plans and local flood risk action plans developed by public administrations. The main finding of the research is the technical advancement that comes with a precise understanding of vulnerability and its resulting issues for better flood risk management.

There are few studies that have developed estimations of the vulnerability of the population to isolation as a result of flood events. The main objective of this study was to provide a methodological proposal that addresses this matter through a series of cartographic instruments. To this purpose, the method was tested in a study area classified as area with significant potential flood risk (ARPSI) in southern Spain. Three methodological proposals were designed to define: (1) the population likely to be isolated within the flood area; (2) the population liable to be isolated by cuts to access roads outside the flood area; (3) the main workplaces involving concentrations of population likely to be isolated. The results demonstrate that the study area has a high degree of vulnerability to the flood risk. The methodological proposal provides detailed results at local level, which is a highly functional tool for flood risk managers. This research shows that, just as in the case of hazard, a deep and detailed knowledge of vulnerability and its consequent problems leads to a better management of flood risk.

En el artículo se aporta una propuesta de catálogo cartográfico de vulnerabilidad adaptadoa los requerimientos de la normativa europea, a los Planes de Gestión del Riesgo y alos Planes de Ámbito Local a aplicar en las ARPS (Áreas de Riesgo Potencial Significativo).Se reflexiona sobre el concepto de vulnerabilidad frente al riesgo, y se puntualizan aspectoscuya definición imprecisa o dispersa dificulta la elaboración de indicadores y cartografías devulnerabilidad consensuadas. Se adjuntan ejemplos de la cartografía propuesta aplicados alárea de inundación del río Guadalhorce (Málaga).
