Introduction
Based at the Centre de Recherche de Climatologie (Dijon) but working in the Crop Insurance Team of Groupama Rhône-Alpes Auvergne, my research work focuses on the evolving agro-climatic risks related to the changing climate variability (dry spells and water balance) in a warming context. This CIFRE PhD thesis follows an engineering degree in agronomy.

The Mont-Blanc massif, being iconic with its large glaciers and peaks of over 4,000 m, will experience a sharp increase in summer temperatures during the twenty-frst century. By 2100, the impact of climate change on the cryosphere and hydrosphere in the Alps is expected to lead to a decrease in annual river discharge. In this work, we modelled the...

In the context of climate change and global warming, the agro-climatic risks should no longer be considered as stationary. For example, recent studies have shown significant changes in the mean behavior of the water cycle as well as in term of temperature. These have caused historical crop losses such as wheat for the year 2016. The main question is now how changes in climate hazards would affect agroclimatic risks and agricultural losses? The PhD thesis will aim to (i) quantify the climatic-hazard and its variability, (ii) characterize the variability and changes of the associated agro-climatic risks, and (iii) assess the individual role of the risk variability and hazard variability in the agricultural losses. Long dry spells and associated hydric stress will be defined and analyzed at regional scale in France for the period 1959- 2018 with the Safran-Isba-Modcou dataset (from Météo France). The specific impact of climate change on agro-climatic risks will be studied through the observed climatic abrupt shift in 1987/1988 and probabilistic methods will be tested to define the spatial-geographical patterns of potential changes in agro-climatic risks and agricultural losses.
Project
This research project is part of the ANR VIP Mont-Blanc project and aims to determine the impact of the loss of glacier surface and climate change (rise of temperatures) on the hydrological cycle of the Arve river in Chamonix.
