Introduction
Geographer, Professor of Geography at the Department of History, Art and Geography (Campus of Ourense, University of Vigo). My research concerns with: geomorphic processes and landforms; geoheritage and protected areas including rural territories and tourism trends; teaching and learning Geography (Higher Education). Much of my work is developing at the Research Group GEAAT (University of Vigo) and the Innovation Group GIDEP (University of Vigo).

Bedrock rivers, whose sedimentary geochemistry has been scarcely investigated, are suitable to test geochemical approaches in order to assess the existence and extent of human alterations in the natural abundance of rare earth elements. This work presents the study of REE contents in fine-grained sediments of the (bedrock) Miño River, in an urban r...

Inland territories hold a great diversity of ecocultural resources, increasingly constituted in tourist products for local development. Their role in improving the socioeconomic conditions and wellness of local communities, as well as in promoting tourism and sustainability, depends on the involvement of public and private actors. The relationships...
Article
The existence of forms sculpted by fluvial erosion is frequent in Bedrock Rivers. Since 1999, the Area of Physical Geography of the University of Vigo (Ourense Campus) has been conducting research on these rock cavities in various reaches of the middle Miño River. The exploratory study that is presented corresponds to the case of a section upstream...
Article
The Miño River is a good example of bedrock rivers, where sediment geochemistry is scarcely studied. Its urban reach when passing through the city of Ourense gathers some characteristics that provide interest to its sediments, like scarcity of fine sediments accumulation and the impact of several human activities. Sediments trapped by potholes and...

El espectro audible del agua configura marcas representativas de diversos ambientes, que definen un patrimonio sonoro con valor científico, cultural, emocional, sensorial y educativo. Desde esta perspectiva, los ambientes fluviales comprenden un amplio espectro de resonancias sonoras. El presente estudio, contextualizado en el ámbito de la investig...

Dende hai máis de unha década, estase a desenvolver no eido da investigación unha relevante liña de traballo sobre o encontro de grandes tradicións de arte rupestre prehistórico no noroeste peninsular, que se viu reforzada nos últimos anos polo achado de sitios con pintura rupestre nas áreas surorientais de Galicia. A identificación de dous sitios...

The capacity of fluvial potholes to trap sediments, together with the geochemical analysis of their stored sediments for environmental assessment, is an overlooked research topic in small bedrock rivers. The present exploratory study is focused on this issue. It was developed in a small river over rock, in the inland territory of Galicia (NW Iberia...

A gravity core (220 cm depth) was collected to investigate the geochemistry, enrichment, and pollution of trace metals in anoxic sediments from San Simon Bay, an ecosystem of high biological productivity in the northwest of Spain. A five-step sequential extraction procedure was used. The Cu, Pb, and Zn contents decreased with depth, with maximum va...
Article
This work addresses the study of a sediment core retrieved in the estuary of the Grande-de-Xubia River (Ria of Ferrol), which is among the first industrialized areas in the Iberian Peninsula and has links to the shipbuilding industry since 1750. The chemical analysis of trace elements (i.e. As, Cd, Co, Cr, Cu, Hg, Mo, Ni, Pb, V, and Zn) was coupled...

El papel de las sinergias entre cultura del vino, identidad territorial y turismo puede ser crucial para el desarrollo rural. El enfoque de la investigación considera la percepción y experiencia de los actores locales sobre esta cuestión, en el territorio de la Denominación de Origen Ribeira Sacra (Noroeste de España). La metodología está basada en...

Los elementos químicos de las tierras raras (REE) se suelen utilizar como trazadores de sedimentos en sistemas costeros. El curso del río Louro está parcialmente situado dentro de la cuenca de drenaje del monte Galiñeiro, que es rico en minerales con REE. Se plantea la hipótesis de que los REE pueden estar presentes en el sedimento del río Louro y...

Abstract: This paper presents a geoecological evaluation of Loznica for the purposes of sports and recreational tourism, based on the quantitative method of diversity. By using this method, we were able to assess the criteria of natural components (relief, forests, water surfaces and climate) of the analyzed area with the help of GIS. In the propos...

Landform assemblages may be used to define sites of geomorphological interest which are resources for rural sustainability. This paper focuses on the valuation and significance of such sites in the context of one European internal border region, illustrated using a case study from the inland mountains of the Spanish-Portuguese border: the Serra do...

Tourism potential is greatly related to destinations’ reorganization and innovation abilities. Throughout the last fifteen years, tourism evolution at the western section of the Sil Canyon (NW Spain) has reflected the transformations facing times of crisis. By assuming tourism as a complex adaptive system, the aims of this research about an inland...

The Anthropocene has been proposed as a new geo-stratigraphic epoch where humans have become a global factor affecting the ecosystems. Estuarine sediments constitute a biogeochemical reservoir where trace elements (TEs) from natural sources mix with a fraction generated by human activities. This study assessed the natural lithogenic imprint of TEs...
Article
The Miño is the most important river in the NW Iberian Peninsula. When it flows through Ourense town (Spain), the attractiveness of the thermal springs hides the importance of the fluvial potholes developed over bedrock. These forms reflect the strength of erosion processes, linked to fluvial incision over time. Potholes have an environmental, dida...

Larouco is an inland cross-border territory located between the South of Galicia (Spain) and the North of Portugal. In Galicia represent a rural space to revitalize that is characterized by the demographic crisis and the decay of the agrarian activity. The knowledge of the perception and opinion of their key actors regarding the territory values an...

En la mayoría de los espacios rurales de montaña la oferta turístico-recreativa está basada en sus recursos naturales. El conocimiento de la percepción y las expectativas de los actores locales respecto a su valor y potencialidad es indispensable para fomentar un turismo sostenible. La Sierra del Larouco es un espacio transfronterizo que se extiend...

The granite caves of Partovia (Ourense, Spain) are studied, in the two types existing in the area: blocks caves and tafone. Age of formation, genesis and morphological characteristics are analyzed. The relationship between his exposure and the performance of Alpine Orogeny in Galicia is analyzed. Archaeological data associated with them are studied...

A total of 216 sculpted forms were registered on the granitic bedrock of the Miño River, northwest Iberian Peninsula. Analysis of in situ measurements (length, width and depth) revealed three general type-sets: incipient forms, longitudinal furrows and circular potholes. Maximum depth and upper radius (at the incision surface) were identified as ke...

Trace element contributions from small rivers to estuaries is an issue barely addressed in the literature. In this work, freshwater flowing into the Ria of Cedeira (NW Iberian Peninsula) was studied during a hydrological year through the input from three rivers, one considered uncontaminated (the Das-Mestas River), a second affected by urban treate...

La morfología de los cauces rocosos refleja la dinámica de la incisión fluvial, relacionada con cambios en diversas escalas espacio-temporales. En el tramo medio del río Miño (Ribeira de Canedo), los procesos erosivos, sobre materiales graníticos, han generado marmitas y surcos en el margen del cauce. La diversidad morfológica está relacionada con...
