Climat : le prix mondial du blé pourrait tripler, selon une étude

16 sources
  • Une étude publiée dans Earth's Future révèle qu'une grave pénurie d'eau dans les zones de culture du blé explique environ 74 % des fluctuations des prix mondiaux entre 2000 et 2021.
  • Avec un réchauffement de 3 degrés, le prix moyen du blé pourrait atteindre environ 364 dollars la tonne, soit près du triple des niveaux de 2010 ajustés de l'inflation, selon les chercheurs.
  • Ces conclusions interviennent alors que les prix du blé ont déjà fortement augmenté en 2026, sous l'effet de la sécheresse et des perturbations du transport maritime en mer Noire, selon l'IFPRI.
