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 …
FUTURS DURABLES POUR LA VILLE MEDITERRANEENNE. Palermo 2019: Green line / Trapani 2020: Recycle city / Marseille 2030: Effect event
2017
Which future for the european city? This is the main issue at the core of the itinerary exhibition of urban projects and architecture aiming at starting a virtuous process of reflections on the theme of the sustainable city in the mediterranean area. The presented projects, beneficiating from on a collaboration among several european institutions, provide a large panorama of answers regarding the transformation of the city of Palermo, Trapani and Marseille. At the same time, these projects question the future of the sustainable city and its transformations by looking at the relation between architecture and infrastructure. Quel est l’avenir de nos villes européennes? Cette question est au c…
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…

Types de configurations pluviométriques sur le bassin méditerranéen, forçages atmosphériques et évènements intenses (1979-2013).
2015
Sixrecurrent and redundant daily rainfall patterns have been extracted over the Mediterranean area from 1979 to 2013: five areassociated to regionals rainfall excess (South-West Mediterranean, Mid-North Mediterranean, East Mediterranean, WestMediterranean and north-west Mediterranean) and one to generalized deficit. Each rainfall pattern is associated with atypical barometric spatial configuration leading to local wind bringing moisture to the coast leading to specific local rainfallsurplus. Rainfall patterns also explain a large part of the spatial characteristics and the probability of occurrence of intenseevents. For example, more than 20% of days of “West-Mediterranean” rainfall pattern…
Épisodes secs en hiver dans le bassin méditerranéen : variabilité et forçages atmosphériques (1957-2013).
2016
The mean number of dry days in winter increased in the Mediterranean Basin during the 1957-2013 period,mainly because of dry spells becoming longer. The shortest events (Very Short Dry Spells) were less frequentwhereas longer events (Short Dry Spells, Medium Dry Spells and Long Dry Spells) were more frequent on theMediterranean Basin. 76 very long events (Very Long Dry Spells – VLDS) occurred during the 1957-2013period. A hierarchical clustering analysis of these VLDS events allows to detect 5 mainly Mediterraneanconfigurations: North-West Mediterranean, West Mediterranean, North-East Mediterranean, South-EastMediterranean and localized events.
