How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
I am a postdoctoral fellow at the university Ben-Gurion (Israel) :) I study the effect of land use change in desert areas on the local climate. I work with big datasets on multiple time and space scales. Previously during my PhD I studied the relationships between the evolution of water resources in the South of France and climate change at the watershed scale
Warming trends are responsible for an observed decrease of water discharge in Southern France (northwestern Mediterranean). Ongoing climate change and the likely increase of water demand threaten the availability of water resources over the coming decades. Drought indices like the Reconnaissance Drought Index (RDI) are increasingly used in climate...
Ce chapitre a été produit par 17 chercheurs de différentes disciplines (hydrologie, hydrogéologie, géographie, science politique, sciences de gestion…), appartenant à une communauté de recherche régionale sur l’eau bien structurée et identifiée aux niveaux national et international. Les contributions réunies ici présentent un état synthétique et ac...
Circum-Arctic glacial ice is melting in an unprecedented mode, and release of currently trapped geological methane may act as a positive feedback on ice-sheet retreat during global warming. Evidence for methane release during the penultimate (Eemian, ca. 125 ka) interglacial, a period with less glacial sea ice and higher temperatures than today, is...
In the Mediterranean, climate change and human pressures are expected to significantly impact the availability of surface water resources. In order to quantify these impacts during the last 60 years (1959-2018), we examined the hydro-climatic and land use change evolution in six coastal river basins of the Gulf of Lion in southern France. By combin...
The Vestnesa Ridge, situated offshore western Svalbard (79N – 1200 m water depth) is a sedimentary drift pierced by several pockmarks which have been releasing methane in the past and which are still active. Foraminiferal stable isotopes have been measured in order to investigate the past methane release events, from the MeBo drilling cores collect...
The aim of this project is to analyse and understand the climatic changes that occured in the past 60 years over a coastal Mediterranean area, located Southern France.We performed analysis on the evolution of the rivers flow and their association with the climatic changes.
