The origin of the ice-free areas of the Hurd Peninsula (Livingston Island, Antarctica)
(Elsevier Ltd., 2024-11-15) Oliva Franganillo, Marc; Palacios Estremera, David; Sancho García, Leopoldo; Fernández-Fernández, José Manuel; Çiner, Attila; Fernandes, Marcelo; Garcia-Oteyza Cira, Julia; Sarıkaya, M.

Spatio-temporal patterns of glacial retreat determine the intensity of geomorphological, hydrological, and ecological processes in the ice-free areas of the Antarctic Peninsula region. The chronology of glacial oscillations in the region following the Last Glacial Maximum (LGM) is still poorly constrained and mostly limited to data from a few sites adjacent to research stations. The Hurd Peninsula, located on Livingston Island (South Shetland Islands), is mainly covered by the Hurd Peninsula Ice Cap (HPIC); there is a ca. 20 km2 ice-free area downvalley of the ice cap in the peninsula’s southern sector in addition to numerous nunataks that protrude above the HPIC. In this study, we present an approach combining two direct surface exposure dating methods, cosmic-ray exposure (CRE) dating and lichenometry, to reconstruct the spatio-temporal patterns of glacial thinning and ice cap retreat on the Hurd Peninsula. To understand the patterns of deglaciation on the peninsula, 26 samples for CRE dating (in situ cosmogenic 10Be) were taken from glacially polished surfaces and moraine boulders along a transect from the nunatak summits to the coast. On the most recent moraines, boulder stabilisation (i.e., indicative of glacier withdrawal) was dated through the longest axis of the 10 largest thalli of the lichen species Rhizocarpon geographicum. Ice thinning might have begun before the LGM at ca. 31.6 ka, when the highest areas close to the coast became exposed, and subsequently accelerated during the LGM at 20-18 ka. The upper surfaces were completely deglaciated between 16 and 14 ka. The HPIC was relatively stable until the mid-Holocene, when neoglacial advances of its outlet glaciers built moraines at ca. 4.5 ka. Subsequently, late Holocene polygenic moraines formed before the development of the external ridges of the most recent moraine system left by the HPIC outlets during the Little Ice Age, at 0.3 ka. The internal moraines correspond to glacial advances from the late 19th and early 20th centuries, as indicated by lichenometric dating. This work presents a comprehensive chronology of glacial oscillations on the Hurd Peninsula, enhancing our understanding of deglaciation patterns and offering insights into glacier dynamics due to climate variability and change.
Stepping on the beaten track? Walking behavior and profiles of cruise passengers in Barcelona
(Elsevier, 2025-04-01) Delclòs-Alió, Xavier; Arias Sans, Albert; Tavafi, Fahimeh; Mejía, Verónica; Catalán, Marta; Gutiérrez, Aaron
Cruise tourism is growing worldwide, accompanied by increasing scrutiny of its impacts. We examine walking behavior of cruise passengers, given the predominance of this means of transportation when exploring cities among this group of visitors. We used Global Positioning System (GPS) and survey data from 793 passengers in Barcelona (Spain). We found that cruise passengers allocate half of their visit time to walking, underscoring the pivotal role of walking in their urban exploration. We identified five distinct walking profiles among cruise passengers, and observed variations in perceptions, including sensitivity to factors like heat, availability of benches for resting, and feeling of crowdedness at visited places. Our study provides valuable insights for urban planners, tourism authorities, and policymakers seeking to address the issues related to visitors' mobility flows in the city, and it contributes to the academic debate on cruise tourism by offering an in-depth understanding of cruise passengers' pedestrian behavior.
La gestión metropolitana del turismo en Barcelona: interdependencias, desafíos y límites
(Asociación de Geógrafos Españoles, Universidad de Cantabria, 2023) Arias Sans, Albert; López i Palomeque, Francesc; Arias Sans, Albert
[spa] El presente articulo analiza la eclosión del turismo en la región metropolitana de Barcelona y explora las interdependencias, los desafíos y los límites de su gestión pública. Enmarcado en los estudios territoriales del turismo urbano y metropolitano, pretende evidenciar el desbordamiento de los ámbitos administrativos territoriales y sectoriales del turismo abriendo así el debate sobre la necesidad de incorporar una visión integrada tanto en el análisis de la realidad turística como en las formas de gestión turística del territorio metropolitano. A través de la utilización de fuentes bibliográficas, estadísticas y documentales, el artículo indaga en el incipiente proceso de institucionalización de la gestión metropolitana del turismo en Barcelona y analiza en profundidad dos cuestiones clave: la regulación de las viviendas de uso turístico y la estrategia de desconcentración de la actividad turística en el entorno metropolitano.
La cambiante localización de la población mayor en las áreas metropolitanas de Barcelona y Madrid. Análisis comparativo de tendencias espaciales
(Federación Española de Sociología, 2023) Gil Alonso, Fernando; Sanz López-Menchero, Laia; Pujadas, Isabel, 1949-

Soil quality in the urban gardens of Barcelona (Spain)
(Springer Verlag, 2024-01-18) Dondini, Cosimo; Úbeda, Xavier; Certini, Giacomo; Francos, Marcos
Purpose Urban agriculture is expanding worldwide and is being promoted by the FAO as a strategic activity because of itsenvironmental, socio-economic, and educational benefits for citizens. In Spain, it is estimated that there are more than 20,000urban gardens. There are many variables to take into account when starting to cultivate an urban garden, among which thequality of the soil is crucial. Nevertheless, some studies have shown high levels of contamination in soils dedicated to urbanhorticulture. The sources of contamination can be various, such as previous unrecognized management and irrigation withpoor quality water, or the addition of polluted compost and other soil improvers. Soil contamination can migrate to vegetablesand fruits, thus entering the food chain.Materials and methods In this study, we analyzed the soils from ten urban gardens in the city of Barcelona, with a specialfocus on possible contaminants. Based on the possibility that irrigation water is a source of pollution, this was also analyzedin all investigated gardens.Results and discussion Some of the waters analyzed for irrigation have a high concentration of salts, and a few of them containnitrites, which are listed as a pollutant. The dominant texture of the soils was sandy clay loam and loamy sand, the pHwas generally high, between 7.87 and 8.41, clearly carbonated, with Ca generally being the dominant exchangeable cation,but without the risk of a high percentage of active carbonates that could make it difficult to grow vegetables. The content inorganic matter was very variable, but in all cases it appeared to be potentially incrementable. The three tests used to checkpossible soil contamination from heavy metals, do not attest to significant pollution.Conclusions The soil quality overall is suitable for growing vegetables and allowing growers to work in these areas incomplete safety. Although it would be necessary to analyze also other toxic elements, not considered in this study, some ofthe measured ones could come from the gases of road transport or even from the port of Barcelona.
Beyond Carbon Tunnel Vision: How Climate Change Hegemony Distorts Environmental Awareness and Hinders Comprehensive Action
(Scilight Press, 2026) Martín-Díaz, Jordi
The planetary ecological deterioration continues unabated despite half a century of global environmental concern and three decades promoting sustainable development. In addition, this period has not served to consolidate an awareness congruent with the nature of the eco-social crisis for most of the population. The paradigm of economic growth is still hegemonic, while the emergence of climate change as the latest environmental emblem has resulted in a modification of the mental frame through which individuals comprehend socio-natural interactions and, consequently, the imperatives for global sustainability. Today, a common misconception is the belief that climate change is the main factor of the contemporary ecological deterioration, and that an eventual decarbonisation of the economy will be sufficient to resolve the eco-social crisis. In contrast to other environmental concerns that have dominated public and political attention, such as the issue of resource scarcity, the rise and consolidation of climate change as an ‘environmental emblem’ is a consequence of its compatibility with the paradigm of economic growth. I argue that the prominence of climate change in environmental discourse, while undoubtedly raising awareness of one of the core planetary boundaries, has, in reality, actively hindered a holistic comprehension of the eco-social crisis. Its alignment and promotion within the growth paradigm is fostering a ‘decarbonisation-only’ mindset that obscures and misrepresents other vital planetary boundaries, such as the biosphere integrity. This perspective paper examines the ascendancy of climate change, considering its cognitive and political implications, before proposing targeted measures to make meaningful progress in both awareness and mitigation policies.
Ciclos económicos y cambios en la movilidad residencial en aglomeraciones urbanas medianas: el caso de El Camp de Tarragona
(Departament de Geografia, 2022-01-01) Gil Alonso, Fernando; Vich Callejo, Guillem
[spa] El Camp de Tarragona, como ámbito de estudio, es una zona poco explorada desde el punto de vista de los procesos de suburbanización. La complejidad es elevada al contar con dos ciudades, Reus y Tarragona, que jerarquizan el territorio, así como unas áreas residenciales periféricas que no solo son parte de su expansión urbana, sino que además son destinos turísticos y de segundas residencias. Utilizando datos de la estadística de variaciones residenciales (EVR), la presente aportación pretende analizar las dinámicas de movilidad residencial del área urbana conformada alrededor de las ciudades de Tarragona y Reus. Para ello, se han analizado la intensidad y la dirección de los principales flujos residenciales en el interior de El Camp de Tarragona, con especial atención a los que tienen origen y destino en ambas ciudades. Los resultados muestran cómo la crisis de 2008 ralentiza el proceso de desconcentración urbana que había caracterizado el territorio durante la década de los 2000 (aunque el cambio de tendencia ya empezaba a detectarse unos años antes), mientras que la poscrisis vuelve a reactivarlo. Los resultados confirman también que se trata de una única área urbana de carácter binuclear (conurbación Tarragona-Reus), y no de dos áreas diferenciadas.
Home-sharing as transnational moorings: Insights from Barcelona
(Routledge, 2022-01-25) Arias Sans, Albert; Quaglieri Domínguez, Alan; Russo, Antonio Paolo
Barcelona, one of the main destinations for Airbnb users, has turned into one of the main stages for the now global debate around short-term rentals and their impacts on resident communities. Criticism has mostly focused on the conversion of housing into conventional tourist apartments while less attention has been paid to the problematization of short-term rentals in primary residences. Important questions thus arise as to whether these allegedly genuine forms of home-sharing should be 'formalised' at all through a regulation, and which type of controls should be applied. Our research helps to excavate this issue, shedding further light on the different logics and practices behind the development of home-sharing, and discusses the limitations of a regulation which is being introduced. To this end, it offers an in-depth analysis of the home-sharing supply in Barcelona, tackling its social and spatial logics, which is framed in the broader debate on processes of social change affecting inner cities. It then focuses on el Raval, one of Barcelona's core neighbourhoods where home-sharing practices have become more diffused, revealing how these practices are strongly correlated with high residential mobility and the presence of a single-dweller childless European resident population. Finally, we argue that home-sharing becomes an equally problematic agency of conversion of housing into a mooring for mobile communities, further contributing to potential gentrification and the displacement of residents.
La paradoja del comercio de proximidad. Consumo, logística y circulación de políticas urbanas
(Mercasa, 2025-10-30) Frago, Lluís
Este artículo analiza la paradoja del comercio de proximidad en el marco del discurso de la “ciudad de los 15 minutos”. A partir de la pandemia y los retos globales, esta propuesta ha ganado prestigio político y académico como fórmula urbana simple y atractiva. Sin embargo, se inscribe en el triunfalismo urbano propio del neoliberalismo, que presenta la ciudad como solución universal a problemas ambientales, sociales y comerciales.El texto muestra cómo, pese a su valor simbólico, el comercio de proximidad está condicionado por dinámicas globales —logística, plataformas digitales, oligopolios y mercado del suelo— que trascienden la escala local. La planificación urbana y los planes de usos municipales resultan insuficientes ante la financiarización y la fragmentación multiescalar. La paradoja es que se ofrecen soluciones locales a problemas estructurales globales. Se concluye que el comercio de barrio sigue siendo vulnerable y requiere políticas redistributivas y de gobernanza metropolitana para garantizar su futuro.
El régimen de tenencia de la vivienda de la población inmigrante en España: cambio y continuidad a partir de los censos de 2001, 2011 y 2021
(Universidad de Almería, 2024-12-23) Orozco Martínez, Carolina; Bayona, Jordi; Gil Alonso, Fernando
[esp]En España, el fuerte incremento de la población debido a la intensidad de los flujos migratorios internacionales añade un nuevo elemento de tensión a un mercado inmobiliario ya afectado por el déficit de nueva oferta y por el desvío a otros usos del parque residencial. Esto ha producido un aumento desmedido del precio de la vivienda, tanto de compra como de alquiler. En este contexto, este estudio analiza la evolución del acceso a la vivienda en propiedad de la población inmigrada, en comparación a la autóctona, utilizando los censos del 2001, 2011, 2021 y la encuesta ECEPOV, que complementa este último. Los resultados del análisis descriptivo (según origen continental, edad y año de llegada a España), validados por una regresión logística, muestran una creciente y generalizada dificultad en el acceso a la vivienda en propiedad de jóvenes, inmigrantes y recién llegados. Si bien en los censos de 2001 y 2011 el porcentaje de propiedad de los inmigrados más adultos llegaba casi a equipararse con el de los españoles, la distancia entre grupos es mayor en 2021. El colectivo de nacidos en el extranjero presenta grandes desigualdades: intergeneracionales entre rangos etarios del mismo colectivo, temporales según el año de llegada e intrageneracionales con respecto a los españoles. Finalmente, la metodología del último censo no es efectiva para captar objetivamente el régimen de tenencia, pues el infraregistro de los alquileres distorsiona sus resultados, que entran en contradicción con los resultados de censos anteriores y con la ECEPOV, que muestra una tendencia opuesta.
La population des villes est-elle ségréguée en fonction de l’âge ? Quartiers vieillissants et quartiers rajeunis dans les grandes métropoles espagnoles
(Université de Lille, 2021-02-12) Bayona, Jordi; Gil Alonso, Fernando; Thiers Quintana, Jenniffer; Pujadas, Isabel, 1949-
Les zones, agglomérations ou aires urbaines fonctionnelles (AUF) espagnoles ont connu une croissance démographique rapide au cours des dernières décennies. Cependant, les différences entre les grandes villes, avec une population plus âgée, et les périphéries suburbaines, avec une population plus jeune, ont augmenté. Cette ségrégation urbaine selon l’âge ne fonctionne pas de la même manière dans toutes les grandes agglomérations espagnoles. L’hypothèse de départ est que la ségrégation par âge devrait être plus importante dans les régions urbaines les plus peuplées et moins intense dans les agglomérations urbaines plus petites, qui présenteraient une plus grande mixité spatiale des groupes d’âge. L’objectif de cet article–qui utilise des données officielles de population au 1er janvier 2016, par section du recensement– est double : d’une part, analyser cette « Géographie du vieillissement et rajeunissement urbains » et, d’autre part, vérifier si les modèles spatiaux trouvés sont communs aux cinq principales métropoles espagnoles : Madrid, Barcelone, Valence, Séville et Bilbao. Les résultats montrent que la ségrégation urbaine selon l’âge dépend plus de sa nature monocentrique –pourcentage de la population de l’AUF résidant dans le principal centre urbain– et de l’intensité du processus de périurbanisation que de la taille de la région urbaine.
Perception, attitude and opinion of the Spanish tourists about the episodes of extreme heat
(Wessex Institute of Technology Press (WIT Press), 2012) Gómez Martín, Belén; Armesto López, Xosé Antón; Martínez Ibarra, Emilio
Here we present the perception, attitude, opinion and behaviour of Spanish tourists when faced with an episode of extreme heat, with temperatures similar to those forecast for summers at the end of the 21st century. This information should help to fill the current gap regarding knowledge of how tourist–citizens perceive certain extreme episodes and behave when faced with them, which could be highly important given that such episodes may become ‘normal phenomena’ as a result of climate change. This information may be useful in devising strategies for the adaptation and future sustainability of tourist destinations.
Tourism and quality agro-food products: an opportunity for the Spanish countryside
(Wiley, 2006-03-08) Armesto López, Xosé Antón; Gómez Martín, Belén
This paper describes the relationships between tourism and the agricultural production of traditional products, the latter having achieved new levels of appreciation in recent years as a result of quality designations. In this context, agro-food products can be considered as gastronomic tourism resources that enable tourism both to be developed and itself become a tool for promoting and commercialising quality agro-food products. These two circumstances merge around a single aim: the local development of areas traditionally regarded as marginal within the regional context. These facts are showed in the Catalan region of Priorat (Spain) where wines support the local development.

Agricultura Ecológica e Internet. Un maridaje de la era postmoderna. Propuesta de acercamiento a una "nueva" forma de producción agraria
(Universitat de Barcelona, 2007-11-01) Armesto López, Xosé Antón
En este artículo se realiza una somera introducción al mundo de la producción agraria ecológica a través de lo que se puede considerar como el abc en Internet. Para ello, el presente trabajo se divide en cuatro secciones: una primera breve introducción conceptual acerca del significado de la agricultura ecológica, una segunda parte dedicada al comentario de algunas páginas web que pueden ayudar al profano a entender el papel que tiene la producción ecológica en diversos organismos oficiales y administraciones públicas, un tercer bloque que presenta a algunas de las organizaciones con más tradición en el fomento y estudio del movimiento ecológico y un apartado final en el que se proponen algunas páginas en las que se puede comprobar el cariz más comercial de este fenómeno.
The Spanish tourist sector facing extreme climate events: a case study of domestic tourism in the heat wave of 2003
(Springer Verlag, 2014) Gómez Martín, Belén; Armesto López, Xosé Antón; Martínez Ibarra, Emilio
This research explores, by means of a questionnairebased survey, public knowledge and perception as well as the behaviour of young Spanish tourists before, during and after the summer holiday period affected by an episode of extreme heat in 2003. The survey was administered between November and December 2004. The extraordinary heat wave of the summer of 2003 can be seen as an example of a normal episode in terms of the predicted intensity and duration of European summers towards the end of the twenty-first century. It can therefore be used as the laboratory setting for this study. In this context, the use of the climate analogue approach allows us to obtain novel perspectives regarding the future impact that this type of event could have on tourist demand, based on a real experience. Likewise, such an approach allows the strategies of adaptation implemented by the different elements in the tourist system in order to cope with the atmospheric episode to be evaluated. Such strategies could prove useful in reducing vulnerability when faced with similar episodes in the future. The main results indicate that Spanish tourists (young segment market) are flexible in adapting to episodes of extremely high temperatures. Their personal perception of the phenomenon, their behaviour and the adaptation measures implemented to a greater or lesser extent before that time, reduce the vulnerability of the sector when faced with this type of event, at least from the point of view of this young segment of the internal national market. In Spain, the episode of extreme heat of 2003 has led to the implementation or improvement of some adaptive measures after the event, especially in the fields of management, policy and education.
Productos agroalimentarios de calidad y turismo en España: estrategias para el desarrollo local.
(Universidad de Zaragoza, 2005) Gómez Martín, Belén; Armesto López, Xosé Antón
Este artículo muestra las relaciones existentes entre el turismo y las producciones agrarias basadas en productos tradicionales, revalorizados en los
últimos tiempos gracias a las denominaciones de calidad. Los productos agroalimentarios se configuran, en este contexto, como recursos turísticos gastronómicos que posibilitan el desarrollo del turismo y, a la vez, el turismo se convierte en herramienta para la promoción y comercialización de los productos agroalimentarios de calidad. Ambas circunstancias se aúnan con un objetivo común: el desarrollo local de territorios tradicionalmente considerados marginales en el ámbito regional.
Potential impacts of P2P acommodation on Rural-mountain areas. A case study from the Catalan Pyrenees (Spain).
(Universität Bonn, 2021-06) Gómez Martín, Belén; Armesto López, Xosé Antón; Cors i Iglesias, Martí
This paper seeks to contribute to existing literature by exploring the potential impacts of Peer-to-Peer (p2p) accommodation on a rural mountain area in the Pyrenees in Catalonia (Spain). The results indicate how widely p2p accommodation can penetrate areas of this kind. The findings suggest that this phenomenon has brought few benefits for local development and has created severe competition for conventional tourism accommodation, despite having a smaller economic impact in terms of job creation and tourist spending. In addition, the relative ease with which it avoids administrative and fiscal controls has negative repercussions for the tax revenues of local authorities. The growth in tourist rental properties is also having harmful effects on the study area in terms of its tourist load capacity, and the high pressure it puts on housing stock is causing shortages in residential housing and sharp price increases.
Tourism, Climate Change and the Mass Media: representation of the issue in Spain.
(Taylor & Francis, 2016) Gómez Martín, Belén; Armesto López, Xosé Antón; Amelung, Bas
This paper sets out to analyse the information dedicated to climate change and tourism in the Spanish press in the Mediterranean region of the peninsula during the period 1990– 2010. Specifically, it seeks to determine the quantitative evolution of media coverage of climate change and tourism and the importance given to this subject. Adequate media attention in both quantitative and qualitative terms could greatly influence public concern and contribute to the social mobilization that will be needed to negotiate/resist the phenomenon in a geographical area in which tourism is a major economic and territorial driver and which is particularly vulnerable to climate change. To construct the corpus, we undertook a systematic analysis of newspaper coverage of tourism and climate change in the media selected; and we carried out content analysis of the 1014 units identified. The results indicate that the coverage is outstanding in quantitative terms. However, the importance given to the subject is quite marginal.
