Arnald Puy
Interdisciplinary scholar assessing the effects of uncertainties, ambiguities and unknowns in model-based research.
About
My work focuses on understanding and appraising uncertainties in contentious phenomena, especially those related with agriculture, climate and water resources. My research aims at providing insights for sustainability and makes use of mathematical models, uncertainty and sensitivity analysis, post-normal science and ethics of quantification.
Projects
Here I list the funded projects in which I am involved, either as a Principal Investigator or a collaborator.
DAWN - Illuminating Deep Uncertainties in the Estimation of Global Irrigation Water Withdrawals
DAWN is a Frontier Research Grant project funded by the UKRI Horizon Europe Funding Guarantee. It aims at embracing ambiguities in irrigation modelling to achieve a more robust understanding of water use for agriculture.
