Postdoc fellowship in statistics applied to soil and climate change
Short Term
Aix en Provence
Soils contribute to most of the main ecosystem functions defined by the Millennium Ecosystem Assessment, as organic carbon sequestration, water supply, erodibility or net primary production among others. They are composed of minerals, organic matter and voids, which nature and organisation in space evolve permanently through time under the action of climate. The ability of soils to provide different ecosystem services depends on several characteristics (texture, pH, CEC, etc.) and this characteristics are generally assume as constant in time whereas it is now clear that at decadal time scales such parameters may change in response to climate modifications. Thus, the role of soil as a climate driver may also change at decadal time scale. Therefore better evaluations of the soil evolution in response to climate change is necessary. Based on this analysis, we propose, to evaluate the change in the main soil ecosystem functions mentioned above (organic carbon sequestration, erodibility) at the 2100 horizon for the Mediterranean basin. To do so we will develop a statistical approach of the link between the WRB soil classes (or subclasses) and the climate. Then the climate changes that will experience the soil class sensitive to climate at the 2100 horizon will be determined. This will be derived from the previous statistical analysis and conducted at both the Global and Mediterranean scale.
Expected skills: the applicant should have extended skills in statistics (an experience of statistical data analysis is mandatory) with a background in soil science, ecology, sciences of the environment or of climate.
