Taking into account soils and climate change in assessing the production potential of a legume crop of interest: pea
In the current context of climate change and increasing pressure on resources, the agricultural production model isbeing questioned. The challenge of a more autonomous, efficient and sustainable production of proteins must bemet by increasing the use of legumes in French cropping systems. The pea (Pisum sativum L.) crop model “AzodynPea” will be used to identify zones and management techniques favorable to the crop in Burgundy-Franche-Comté(eastern France), taking into account abiotic stresses, such as winter frost or water deficit. The first step in this processis the mapping of current soil properties and current and future climate characteristics of the region. Regionalizeddaily climate …
Regional projection of winter frost risk on a legume crop due to warming in a temperate climate
International audience; Pea (Pisum sativum L.) is an important annual legume crop grown in temperate regions for its high seed nitrogenconcentration and environmental benefits. In the recent climate warming, a subtle evolution of the winter cropfrost risk was observed: a paradoxical increase of frost stress events and a frost stress intensity decrease (Castel etal. 2017). Such results are questioning the future winter frost risk for peas. We assessed the winter frost damageevolution along 2006 to 2100 in Burgundy-Franche-Comté (a French region - western part of Europe). The approachis based on the combination of i) a dynamical downscaled climate data of two RCP trajectories (4.5 and 8.5) (B…
