avec le changement climatique. Le changement climatique, en tant que composante du changement global, exacerbe les risques pour l’environnement, la biodiversité et les sociétés, voire en génère de nouveaux. Les évolutions tendancielles du climat mais aussi l’accroissement de la fréquence et de l’intensité des phénomènes atypiques (vague de chaleur, de froid...), et leurs impacts dans les domaines de l’agriculture, de l’alimentation, de la forêt, de la gestion de l’eau et des déchets, ainsi que sur la santé végétale, animale et humaine sont au cœur de nos travaux. Ceux-ci visent l’atténuation de ce changement, l’adaptation des systèmes alimentaires et des écosystèmes en réduisant leur vulnérabilité et en augmentant leur résilience par le développement des connaissances et l’appui aux politiques publiques. Nos recherches participent également à améliorer la prévention et la gestion des risques.</div> </div> </header> <div class="field-component-listing"> <div class="paragraph paragraph--type--paragraph-wysiwyg paragraph--view-mode--default"> <section class="Wrapper Wrapper--gray"> <div class="Wrapper-content"> <header class="SectionHead"> <div class="SectionHead-titles"> <h2 class="SectionHead-title"> S’adapter au changement climatique et gérer les risques </h2> </div> </header> <div class="Wrapper-columns"> <div class="Wrapper-colMain"> <div class="RichText" data-summary-content> <p><span><span><span><span>Le <strong>changement climatique</strong> a pour conséquences une augmentation de la fréquence, de l’intensité et de la durée des canicules et des sécheresses, mais aussi probablement des précipitations.
