Impact du changement climatique et
du changement d’occupation des sols<\/strong><\/p>\n\n\n\n

Dans le cadre des s\u00e9minaires HSM, pr\u00e9sentation le 27 janvier 2022<\/p>\n\n\n\n

R\u00e9sum\u00e9 <\/strong>:<\/p>\n\n\n\n

Les hydrosyst\u00e8mes karstiques sont des environnements tr\u00e8s sensibles aux activit\u00e9s anthropiques (AA) et aux variations hydroclimatiques, telles que celles entra\u00een\u00e9es par le Changement Climatique (CC).<\/p>\n\n\n\n

Au sein de la ZoneCritique (ZC), ces milieux sont les plus r\u00e9actifs et \u00e9galement les plus vuln\u00e9rables \u00e0 ces for\u00e7ages qui peuvent modifier le transfert interne rapide des \u00e9l\u00e9ments dissous, et notamment des contaminants.<\/p>\n\n\n\n

Ces syst\u00e8mes karstiques sont donc d\u2019excellents candidats pour \u00e9tudier l\u2019impact du CC et des AA sur les ressources en eau et sur les cycles biog\u00e9ochimiques des \u00e9l\u00e9ments, notamment C et S, fortement perturb\u00e9s par les changements d\u2019occupation des terres,<\/p>\n\n\n\n

ainsi que par les retomb\u00e9es atmosph\u00e9riques li\u00e9es aux AA (d\u00e9p\u00f4ts acides).<\/p>\n\n\n\n

L\u2019objectif de cette th\u00e8se est donc de comprendre le fonctionnement hydro-biog\u00e9ochimique des syst\u00e8mes karstiques en milieu temp\u00e9r\u00e9 et d\u2019identifier l\u2019impact du CC et des AA. Ces questionnements ont \u00e9t\u00e9 abord\u00e9s \u00e0 diff\u00e9rentes \u00e9chelles spatiales et temporelles<\/p>\n\n\n\n

sur le bassin versant karstique du Baget (BC, Pyr\u00e9n\u00e9es Ari\u00e9geoises, bassin forestier, multilithologique et quasi pristine) et sur une vingtaine d\u2019autres bassins versants karstiques \u00e0 l’\u00e9chelle r\u00e9gionale (Pyr\u00e9n\u00e9es et Massif Central).<\/p>\n\n\n\n
