Aim: To compare the burden of disease in Spanish patients with axial spondyloarthritis (axSpA) vs other European countries (OEC). Methods: Data from 2846 unselected patients from the European Map of Axial Spondyloarthritis (EMAS) and the Atlas of Axial Spondyloarthritis in Spain (Atlas) were collected through online surveys. Comparative analysis was carried out between Spanish patients (2016) and patients from 12 OEC ( 2017-2018). Socio-demographic characteristics, life habits, and patient-reported outcomes (Bath Ankylosing Spondylitis Disease Activity Index 0-10, spinal stiffness 3-12, functional limitation 0-54, the 12-Item General Health Questionnaire [GHQ-12] for psychological distress 0-12) were compared. Chi-square and Mann-Whitney tests were used for qualitative and quantitative variables respectively. Results: 680 (23.9%) Spanish axSpA patients were compared to 2166 axSpA patients (76.1%) from OEC. Compared to Spain, the OEC group had a higher percentage of females (64.1% vs 52.5%; P < .001) and university-educated participants (51.7% vs 36.9%; P < .001). Spanish patients showed a greater diagnostic delay (8.5 ± 7.7 vs 7.2 ± 8.6 years; P < .001), visits to orthopedic specialists before diagnosis (56.9% vs 25.3%; P < .001), human leukocyte antigen-B27 carriership (77.1% vs 70.1%; P = .003), disease activity (5.7 ± 2.0 vs 5.4 ± 2.0; P = .024), and higher unemployment rates (21.7% vs 9.2%; P < .001). Despite lower rates of diagnosed anxiety and depression, Spanish patients were at higher risk of psychological distress according to the GHQ-12 (5.7 ± 4.5 vs 4.8 ± 4.0; P < .001). Conclusion: Compared to European axSpA patients, Spanish patients experience a longer diagnostic delay and greater psychological distress. Being wrongly referred to orthopedic specialists and facing a more precarious labor scenario appear as possible causal factors, highlighting the need to increase the number of rheumatologists, the training of healthcare professionals, and improving axSpA patients' working conditions
A global-scale overview of precipitation-deficit flash droughts
(Springer Science and Business Media LLC, 2021) Limones Rodríguez, Natalia; Universidad de Sevilla. Departamento de Geografía Física y Análisis Geográfico Regional
Flash droughts are defined as fast and intense dryings of the land system. In these episodes, declines in precipitation deficits are often accompanied by rapid intensifications of evaporative demand, leading to sharp soil moisture decreases and noticeable agricultural and environmental impacts. This research presents a straightforward framework for global historical characterization of precipitation-deficit-related flash droughts, examining the extent to which this type of hazard can be described using only pentad rainfall data. The Drought Exceedance Probability Index was applied to global gridded high-resolution rainfall data for 1979 - 2020. Sharp upsurges in the pentad index series were detected and counted to analyze the occurrence of precipitation-deficit flash droughts. The precipitation characteristics associated to flash drought incidence were explored to learn if some rainfall regimes or times of the year are more prone to the phenomenon, which could help societies become more prepared for the risk. It was observed that climates with marked inter-annual and intra-annual rainfall variability record more flash droughts, especially when that variability is significant during the local wet seasons. This is the case of regions with erratic rainfall generation mechanisms such as Mediterranean climates or monsoon climates. The episodes mainly occur during what is expected to be the humid time of the year, when they can produce greater impact. The methodology used was able to detect the most intense events described in previous studies that used variables associated to soil moisture dryness, confirming the role of acute precipitation deficits in triggering them.
A machine-learning hybrid-classification method for stratification of multidecadal beach dynamics
(Taylor and Francis, 2022) Rodríguez Galiano, Víctor Francisco; Guisado Pintado, Emilia; Prieto Campos, Antonio; Ojeda Zújar, José; Universidad de Sevilla. Departamento de Geografía Física y Análisis Geográfico Regional; Ministerio de Ciencia, Innovación y Universidades (MICINN). España; Junta de Andalucía
Coastal areas are one of the most threatened natural systems in the world. Environmental beach indicators, such as erosion and deposition rates of exposed beaches in Andalusia (640 km), were calculated using the upper limit of the active beach profile and detailed orthophotos (1:2500) for the periods 1956–1977, 1977–2001 and 2001–2011. A hybrid classification method, both supervised and unsupervised, based on machine-learning (ML) techniques was then applied to model beach response and dynamics for this 55-year period. The use of a K-means technique allowed stratification into four beach groups that have responded similarly in terms of coastline mobility and erosion/deposition patterns. Furthermore, the application of a classification and regression tree (CART) based on the K-means results helped to identify the threshold values for erosional and depositional rates and the period that characterises each cluster or stratum, enabling correct classification of 1415 out of 1509 beaches (93.77%).
A Partially Non-Compensatory Method to Measure the Smart and Sustainable Level of Italian Municipalities
(MDPI, 2021) Ciacci, Andrea; Ivaldi, Enrico; González Relaño, Reyes Manuela; Universidad de Sevilla. Departamento de Geografía Física y Análisis Geográfico Regional
A smart sustainable city (SSC) is a paradigm that encapsulates the latest lines of development in multiple fields of research. The attempt to converge towards a model of sustainable urban life, made difficult by increasing anthropic pressure and polluting activities conducted by man, is also reflected in the intentions of public institutions to take measures of environmental risk mitigation. The change towards more liveable cities must also include the adoption of more far-reaching measures in various sectors. The objective of our work was to provide an analysis in order to assess which of the Italian provincial municipalities were most closely related to the paradigm of SSCs. This aim was pursued through a comparison based on the results of a partially non-compensatory quantitative method, known as the Pena’s Distance method (DP2). The smartest and most sustainable cities, such as Siena, Milan and Padua, were not identified on the basis of common urban characteristics but rather derived from the combination of distinctive and functional elements in the pursuit of a strategic approach aimed at fully exploiting the resources of each area. Moreover, at a macro-geographical level, from the analysis emerged the presence of contiguous clusters, i.e., areas in which a major concentration of smart sustainable municipalities tended to form
A place in the sun: the British housing market’s (de)construction of Andalusia
(Routledge, 2019) García Martín, Miguel; Villar Lama, Arsenio; Cruz Mazo, Estrella Candelaria; Universidad de Sevilla. Departamento de Geografía Física y Análisis Geográfico Regional; Universidad de Sevilla. HUM875: Estudios Territoriales y Turísticos
Andalusia has become one of the main destinations for British residential tourists, attracted by leisure, a mild climate and the search for a better lifestyle. Prompted by its interest in selling houses, the real estate industry has devised an image of the Andalusian landscape that is, to all intents and purposes, partial and biased. The purpose of this research is to assess the importance of the elements and features that characterise this particular vision of this Spanish region, paying particular attention to more rural inland areas. For this, an empirical study has been conducted based on content analysis of real estate websites targeting British buyers. This study has revealed that: (i) the misrepresented and romantic projection of the image of Andalusia still persists to a certain extent. Among the main elements and attributes that characterise the landscape are all those that emphasise the region’s sublime, picturesque and exotic nature; other main landscape qualities and unique areas, specifically, any that today enjoy natural or cultural legal protection due to their heritage value, are less important in this cultural construction; (ii) the various parts of Andalusia are treated unequally. Malaga province and the rest of the Baetic Mountains are much better represented than other areas (the Guadalquivir Valley and the Sierra Morena mountains). This imbalance sometimes results in a distorted construction of the territory. This way of conceiving Andalusia puts Malaga at the heart of the region, and the further from the Costa del Sol, the more peripheral the regions become; (iii) the complexity of the landscape as a cultural expression is reduced to a set of simplified features that can be easily digested by a social group focused not on experiencing, but on consuming the landscape.

Accessibility of rail trails in Huelva, Andalusia (Spain)
(Taylor and Francis, 2017) Ventura Fernández, Jesús; González Relaño, Reyes Manuela; Gavira Narváez, Antonio; Universidad de Sevilla. Departamento de Geografía Física y Análisis Geográfico Regional
The rail trails (converted disused railways) are infrastructures which can be reused mainly as non-motorised itineraries for hiking and cycle touring. Andalusia (Spain) has a network of 1442 km of disused railways, out of which 606 km are found in Huelva province (42.1%) as heritage from its former mining activity. The aim of this article is to devise a method which determines the real accessibility to rail trails and the volume of resident population who can reach them in a time period of 5, 10 and 15 minutes by road in a private vehicle. This process involves the determination of real accesses with accuracy and the differentiated calculation of the average speed on the different types of routes. The method is used for the three rail trails which currently exist in Huelva (98.6 km), having as a result a Map at a scale of 1:325,000.
‘Accommodation space’ at beaches in Andalusia: calculations derived from the 2013 shoreline data model and the use of spatial databases
(Asociación Española de Geografía: Grupo de Tecnologías de la Información Geográfica, 2019) Prieto Campos, Antonio; Díaz Cuevas, María del Pilar; Ojeda Zújar, José; Universidad de Sevilla. Departamento de Geografía Física y Análisis Geográfico Regional
This paper presents the results of an update of the Andalusian shoreline data model with inclusion of the concept of ‘accommodation space’. This variable, together with the erosion rates, is essential for understanding the current dynamics and future evolution of Andalusian beaches. The results calculated for the 2013 shoreline (extracted from the 2013 orthophoto, IECA Institute of Statistics and Cartography of Andalusia) show how 40 % of Andalusian beaches do not have accommodation space, mainly due to occupation of such space by urban development and the existence of cliffs. Conversely, 60 % of Andalusian beaches do have accommodation space, allowing regression of the shoreline and hence adjustment of the beach to erosion and flooding processes. About 85 % of those spaces are situated on the Atlantic façade, where they attain great length, mainly due to less anthropic pressure and the presence of protected natural areas. The beaches on the Mediterranean façade have the smallest accommodation spaces and are consequently more vulnerable to flooding or erosion processes, including, in some cases, higher risk of disappearance in the future.

Actualización curricular y docente mediante talleres prácticos: la experiencia del taller de elaboración de mapas de contaminación acústica
(Universidad de Alcalá. Departamento de Geografía. Universidad de Alcalá. Servicio de Publicaciones, 2012) Pedregal Mateos, Belén; Vallejo Villalta, Ismael; Aguilar Alba, Mónica; Universidad de Sevilla. Departamento de Geografía Física y Análisis Geográfico Regional; Universidad de Sevilla. Departamento de Geografía Humana
El taller de elaboración de mapas de contaminación acústica ha propiciado el contacto y colaboración de profesores y alumnos con empresas especializadas en la elaboración de mapas de ruido, así como la colaboración entre el profesorado de distintas asignaturas relacionadas con los Sistemas de Información Geográfica y la Estadística de la Licenciatura en Geografía de la Universidad de Sevilla. Al mismo tiempo la celebración del taller ha supuesto el refuerzo de la formación práctica del conjunto de asignaturas implicadas y la adaptación de la oferta formativa a la gran demanda social existente respecto a la preparación técnica de los futuros egresados en temas ambientales. La experiencia ha resultado muy positiva para profesores y alumnos, en la medida en que la colaboración con profesionales relacionados con las materias impartidas motivan al estudiante, al tiempo que permiten la actualización de los curricula y prácticas docentes de manera flexible y adaptativa

Advanced digital skills of the Spanish population from 2015 to 2021. Socioeconomic and geographical factors according to an ordered probit model
(Elsevier, 2023) Ruiz Rodríguez, Francisca; Akoudad-Ekajouan, Abdennour; González Relaño, Reyes Manuela; Universidad de Sevilla. Departamento de Geografía Física y Análisis Geográfico Regional; Ministerio de Ciencia, Innovación y Universidades (MICINN). España
The increasing digitalisation of the economy, especially after the COVID-19 pandemic, requires the population to have advanced digital skills. In a decentralised country such as Spain, it is necessary to identify the population’s model of digital skills acquisition by taking geographical variables into account. To this end, the aim of this research is to analyse the impact of socioeconomic and geographical variables on the level of advanced digital skills of the Spanish population including two spatial levels: regional (Autonomous Communities) and local (provinces) from 2015 to 2021. An ordered probit model is used with microdata provided by the Spanish National Statistics Institute’s Survey on Equipment and Use of Information and Communication Technologies in Households (ICT_H) for 2015, 2019 and 2021. The results of this study show that socioeconomic factors have a greater influence than geographical factors on the digital skills acquisition model. The model has undergone changes with the emergence of the COVID-19 pandemic, with an increase of advanced digital skills among the employed and the unemployed compared to inactive persons. Moreover, the importance of educational level is corroborated and the importance of daily Internet use increased during the pandemic. There was also less regional than provincial dispersion in the probability of converging in digital skills with the region and province of Madrid. This study contributes the evolution over time of the model of digital skills acquisition with socioeconomic and geographical variables, identifying intra-regional differences and indicating whether there is spatial dependence between regional and local levels in Spain, with a view to reducing them in terms of sustainability.

Alteración hidromorfológica y estado ecológico del tramo bajo del río Bembézar. Cuenca del Guadalquivir, España
(Centro Ciencias Humanas & Sociales - CSIC, 2021) García Martínez, Belén; Universidad de Sevilla. Departamento de Geografía Física y Análisis Geográfico Regional; Universidad de Sevilla. HUM697: Geografia Fisica Aplicada y Patrimonio
El río Bembézar, con una cuenca próxima a 2000 km2 de superficie y una capacidad de agua embalsada de 355.5 hm3, presenta evidencias de alteración hidromorfológica en su tramo bajo. A partir del estudio de series de caudales (2000-2019) aportadas por el Sistema Automático de Información Hidrológica del Guadalquivir y del análisis de las fotografías aéreas de distintos años (1956 y 2010), las principales alteraciones detectadas son las siguientes: disminución en un 58% del caudal circulante por el cauce, incremento de la irregularidad estacional con siete meses de aguas bajas, ausencia de caudal ecológico el 66% de los días, funcionalidad de la llanura de inundación sólo en crecidas extraordinarias, cambio en el patrón morfológico del río, reducción de la anchura media del cauce en un 53%, incisión generalizada en todo el tramo e invasión de especies exóticas.Por su parte, la valoración del estado ecológico que realiza de esta masa de agua el Organismo de cuenca competente evoluciona de malo en 2015 a peor que bueno en 2018, como consecuencia de los malos resultados que aportan los indicadores biológicos; pese a que el objetivo medio ambiental para esta masa de agua era el de buen potencial ecológico en 2015. Se pone de manifiesto, asimismo, la poca idoneidad tanto de los criterios hidromorfológicos utilizados en la definición del estado ecológico como de las actuaciones que se ejecutan para garantizar la conservación de cauces y riberas.
