Name of the speaker : Matteo Zampieri
Affiliation : JRC
Laboratory organizer : LMD
Date and time : 12-12-2019 14h00
Location : Salle Froidevaux - E314 - 24 rue Lhomond - 3ème étage (bouton ascenseur 6)
Summary :

The original ecological meaning of the term resilience refers to the largest pressure that a system can cope with before changing its internal structure and losing its functioning capacity (Holling 1973). Afterwards, the concept of resilience has been introduced in other fields such as engineering and social sciences and modified to the point that resilience became an elusive concept, difficult to determine quantitatively. I'm proposing a measure theory for resilience derived directly from its original definition applied to production systems such as crops and natural vegetation. I will present several applications such as the estimations of the relationship between diversity and production resilience, of the effects of the Atlantic Multidecadal Oscillation on the resilience of global maize production, of the effects of climate change on the resilience of wheat production in the Mediterranean, of the relationships between vegetation resilience and green water resources resilience and of the effects of climate change on green water resources resilience.
