El Corredor Mediterráneo
2016
El Corredor Mediterráneo, como proyecto de eje ferroviario, constituye un elemento clave de la planificación española y europea. Además de tener un papel de infraestructura de transporte, también cristaliza en cuestiones económicas y políticas a distintos niveles territoriales. Representa un cambio en la lógica de ordenación del territorio, al reforzar el eje litoral en detrimento de los enlaces radiales con la capital. En este libro se propone entender cómo el Corredor viene a ser un patente factor que incita a revisar el papel de los distintos actores implicados -políticos, económicos, institucionales...-, así como a reinterpretar los paradigmas de la ordenación del territorio e interroga…
Effects of different amendments (organic matter and hydrogel) on the actual evapotranspiration and crop coefficient of turf grass under field conditi…
2020
The irrigation schedule in arid areas has to be efficient in order to reduce losses due to evaporation and deep infiltration. Irrigation optimization poses the need to establish with precision the value of actual evapotranspiration (ETa), and the crop coefficient (Kc). The water soil availability can be increased using hydrogel and organic matter amendments, and their effects could vary ETa and Kc. The aim of this study was to determine the ETa, and Kc of an experimental site with lysimeters on the Spanish Mediterranean coast cropped with a turf grass variety, Agrostis stolonifera ‐L‐93, under field conditions, and amended with hydrogel and organic matter. Reference evapotranspiration (ET0)…
Las crecidas en ramblas valencianas mediterráneas
2001
This paper takes into account the characterisation of ephemeral stream hydrology from Mediterranean environments. The heavy floods that these countries suffer are due to firstly, the physical watershed features (steep slopes, scarced vegetation cover and thin soils) and, secondly, to the intense and variable rainfall. Large quantities of precipitation fall in a matter of hours, or even minutes, over very steep catchments, causing catastrophic flash-floods, with very pointed hydrographs and short time lags. Using hydrological daily data from the Rambla de la Viuda basin and five-minute data from both Barranc de Carraixet and Rambla de Poyo basins, we have analysed the rainfall- runoff proces…
Production, gestion et utilisation des outillages lithiques du Chasséen méridional
2006
Is the opposition between specialized and non specialized productions a key to characterizethe lithic assemblages from the southern Chassey Culture ? The former have been used to define the culture itself and to build up theories based on craft specialization to approach the social organization of these Neolithic groups. Our first studies about the latter show that they reveal specific technical activities conducted at the site or that they are useful to build up interpretation on both site functions and social organization.We base our study on a corpus of sites localized in the south of France–from Alpes-Maritimes to Lot–between 4300 and 353500 BC cal. Different site function are here repr…
Campaniformes et cultures locales en France méditerranéenne
2006
Since the 1998 Riva del Garda conference and the synthesis coordinated by J Guilaine (2001), the new bell beakers archaeological data of Mediterranean France make it possible to specify the relations between the Bell Beakers ones and indigenous populations of the final Neolithic in this area. The phase of synchrony between Bell Beakers and local cultures, highlighted for the Early Bell Beakers between 2500 and 2400 before our era, can undoubtedly be wide at the first times, at least, development of the regional groups of recent bell beakers ("Rhodano- Provençal" and "Pyrénéen"). In parallel, differences in relations between these Bell beakers and the indigenous populations can be supposed i…

Thermal remote sensing from Airborne Hyperspectral Scanner data in the framework of the SPARC and SEN2FLEX projects: an overview
2009
Abstract. The AHS (Airborne Hyperspectral Scanner) instrument has 80 spectral bands covering the visible and near infrared (VNIR), short wave infrared (SWIR), mid infrared (MIR) and thermal infrared (TIR) spectral range. The instrument is operated by Instituto Nacional de Técnica Aerospacial (INTA), and it has been involved in several field campaigns since 2004. This paper presents an overview of the work performed with the AHS thermal imagery provided in the framework of the SPARC and SEN2FLEX campaigns, carried out respectively in 2004 and 2005 over an agricultural area in Spain. The data collected in both campaigns allowed for the first time the development and testing of algorithms for …
Le rôle du patrimoine dans le projet urbain et d’architecture Marseille et Tunis, villes de la Méditerranée
2014
Cette travail de recherche porte sur la mise en valeur et la transformation du patrimoine urbain et architectural à travers la pratique du projet urbain dans la ville méditerranéenne. La recherche étudie également la relation qui existe de nos jours entre le patrimoine et la durabilité environnementale, notions qui ne sont plus opposées mais complémentaires, dans une construction réciproque des identités et des différences conduisant à leur redéfinition. Certains projets durables réalisés en Méditerranée, ces dernières années, révèlent une façon inédite de comprendre le développement de la métropole à partir du patrimoine de la ville consolidée, en tant que vecteur mobilisateur de changemen…

What is a tree in the Mediterranean Basin hotspot? A critical analysis
2019
Background: Tree species represent 20% of the vascular plant species worldwide and they play a crucial role in the global functioning of the biosphere. The Mediterranean Basin is one of the 36 world biodiversity hotspots, and it is estimated that forests covered 82% of the landscape before the first human impacts, thousands of years ago. However, the spatial distribution of the Mediterranean biodiversity is still imperfectly known, and a focus on tree species constitutes a key issue for understanding forest functioning and develop conservation strategies. Methods: We provide the first comprehensive checklist of all native tree taxa (species and subspecies) present in the Mediterranean-Europ…
