Can agroforestry protect crops from cavitation / hydraulic failure ?

Est-ce que l'agroforesterie peut protéger les cultures contre la cavitation et la rupture hydrolique

Résumé

Agroforestry systems (AFS) are pushed as an adaptation solution of agrosystems against climate change (CC) (IPCC, 2022). Given the time constraint of tree growth, modelization and simulation are necessary. In this regard, the Hi-sAFe model (Dupraz et al. , 2019) is one solution available. This model has been successfully used to assess the biophysical impact of CC on AFS (Reyes et al., 2021). However, by design, the Hi-sAFe model is not able to fully represent the physiology of plants (both crop and trees) under hydric stress and hydraulic failure situation. The SUREAU model (Cochard et al., 2021) is a mechanistic model focused on the hydraulic architecture of plants and the water resistance and water capacitances of their organs. Thanks to the SUREAU model, it is possible to represent , at plant scale, the hydraulic failure that can happen in situation of hydric stress. Here we propose a linkage of the Hi-sAFe model to the SUREAU to investigate the possibility to model hydraulic failure at plant level in agroforestry plot.
