The study of the many types of natural and manmade cavities in different parts of the world is important to the fields of geology, geophysics, engineering, architectures, agriculture, heritages and landscape. Ground-penetrating radar (GPR) is a noninvasive geodetection and geolocation technique suitable for accurately determining buried structures. This technique requires knowing the propagation velocity of electromagnetic waves (EM velocity) in the medium. We propose a method for calibrating the EM velocity using the integration of laser imaging detection and ranging (LIDAR) and GPR techniques using the Global Navigation Satellite System (GNSS) as support for geolocation. Once the EM velocity is known and the GPR profiles have been properly processed and migrated, they will also show the hidden cavities and the old hidden structures from the cellar. In this article, we present a complete study of the joint use of the GPR, LIDAR and GNSS techniques in the characterization of cavities. We apply this methodology to study underground cavities in a group of wine cellars located in Atauta (Soria, Spain). The results serve to identify construction elements that form the cavity and group of cavities or cellars. The described methodology could be applied to other shallow underground structures with surface connection, where LIDAR and GPR profiles could be joined, as, for example, in archaeological cavities, sewerage systems, drainpipes, etc.

Conviene entender a su vez cómo y por qué se descompuso ese sistema, aprendiendo del pasado para avanzar hacia un urbanismo comprometido con la satisfacción de las necesidades humanas de alimentos de una manera más justa y más respetuosa con el planeta. El análisis histórico se centra en el tramo medio del valle del Duero. Los sistemas territoriales que se han sucedido desde principios del siglo XX responden a tres modelos del sistema agroalimentario, que se asocian con las distintas etapas nutricionales. Hay una correlación entre modelo nutricional de superación de la desnutrición, agricultura familiar, en la zona hasta 1950; modelo de consumo de masas y sobrealimentación, agricultura industrializada, que se extiende hasta 1985; y modelo de consumo segmentado, agricultura terciarizada, que dura hasta nuestros días. En esta última fase conviven dos tendencias: una hacia la jerarquización y el productivismo tecnificado y otra hacia la multifuncionalidad y la recampesinización que se reapropia de las innovaciones técnicas. El urbanismo cuenta con herramientas y mecanismos podrían aportar una dimensión espacial y funcional hasta ahora descuidada. Hay indicios que apuntan que el momento para reconsiderar los sistemas agroalimentarios también desde el urbanismo, favoreciendo su relocalización y una transición agroecológica, ha llegado.Palabras clave:Sector agroalimentario / Territorio / Región agraria / Resiliencia / Sostenibilidad AbstractThe historical review of the relationship between territory and agrifood system provides key lessons to help rebuild the territorial structure, seizing the opportunity offered by a renewed interest in local and sustainable food. The historical transdisciplinary research focuses on the middle reaches of the Douro valley (Castilla y Leon, Spain). After the analysis of the evolution of the region since 1900, it can be concluded that the territory has been organized over time according to three models of food system that are in turn linked to different nutritional stages: a) the nutritional stage of overcoming malnutrition is related to family agriculture, which persists until 1950; b) the model of mass consumption and overeating, built on an industrialized agriculture, which runs until 1985; c) and, finally, the model of consumer segmentation associated with terciarized agriculture, which lasts until present time. Actually two trends coexist: one towards hierarchisation and tech-based productivism, and another one towards multifunctionality and peasantization. Spatial and urban planning are already equipped with mechanisms to integrate the functional and spatial dimension in the reconsideration of agrifood systems. We are missing opportunities, but there are indications that suggest that the moment to relocalize the agri-food system and to foster agroecological transition, has arrived.Keywords:Agri-food system / Territory / Agricultural region / Resilience / Sustainability
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
