| Human pressures on ecosystems have increased significantly over the last decades, and especially Mediterranean coasts are strongly impacted by the development of big cities and industrialized area, such as the Bay of Marseille. Prior to any investigations on ecological or contamination impacts, it was necessary to understand sediment dynamics and its response to natural extreme events such as storm or heavy rainfall events. In situ observations were dedicated to understand the behavior of bed sediments, and their spatial distribution. A benthic station was deployed for three months to observe the impact of extreme events on hydrodynamics and sediment dynamics in a critical zone of the study area. These measurementswere used to calibrate and validate the... |

| RESUMEN: Estudiamos el precio de la tierra para uso agrario y las variables que determinan su evolución en España, tratando de identificar qué parte de la subida de precios observada se justifica por elementos «internos», relacionados con la renta agraria esperada, y cuál proviene de elementos externos o especulativos, vinculados a cambios en el uso del suelo. Además se relaciona el ciclo de precios con la aceleración de la especialización en el ámbito regional y la integración en la PAC. La novedad de este trabajo consiste en identificar, mediante técnicas de datos de panel, factores no fundamentales (presión urbanizadora, creación de regadíos, cambio demográfico) que, además de los fundamentales (ingresos esperados y localización geográfica) determinan... |
