DESCRIPTION:Dr. Francesca Bassani\nAbstract:\n\n\nThe increasing impacts 
 of climate change are causing serious challenges for agricultural producti
 vity and global food security. A key concern is how changing climate condi
 tions\, such as precipitation and temperature\, might influence the suitab
 ility of croplands and agricultural systems\, with significant consequence
 s for future food production and related policies. In this study\, by esta
 blishing relations between soil and climate factors and crop yield\, we ad
 opt a data-driven model to evaluate future climate-driven changes on suita
 bility of twelve major crops produced worldwide. We consider the IPCC’s 
 four Global Warming Levels (GWLs +1.5\, +2\, +3\, +4°C) to assess the fut
 ure potential shifts in global cropland suitability relative to the baseli
 ne period of 1985-2014. Our results feature an overall future decrease in 
 cropland suitability around low-mid latitudes\, and a potential increase f
 or certain crops around mid-high latitudes. In particular\, more than 75% 
 of the crops that are currently harvested in semi-arid and tropical areas 
 will become less suitable in the future\, with increasing severity for hig
 her GWLs\, if no adaptation strategies will be implemented. On the contrar
 y\, staple crops such as barley\, maize and wheat will become more suitabl
 e at higher latitudes\, especially between the current humid continental a
 nd subarctic climate zones. These findings underscore the importance of in
 tegrating climate-soil interactions into crop adaptation planning to bette
 r anticipate regional vulnerabilities and guide sustainable agricultural d
 evelopment.\n \n\n\n\n\nBiography:\n\n\n\nFrancesca Bassani is a postdoct
 oral researcher at the Laboratory of Catchment Hydrology and Geomorphology
  (CHANGE Lab\, advisor: Sara Bonetti) at EPFL Valais Wallis\, where she co
 ntributes to the development of mathematical frameworks for the assessment
  of soil and water sustainability under climate change. She obtained her P
 hD in Civil and Environmental Engineering (2023) and MSc in Civil Engineer
 ing (2018)\, with major in Hydrology and Hydraulics\, from the Polytechnic
  University of Turin\, Italy.\n\n
