L\u2019arbre n\u2019est pas une m\u00e8che inerte entre le sol et l\u2019atmosph\u00e8re : il est capable de r\u00e9guler sa consommation en eau.

Le contexte de telles recherches est d\u2019actualit\u00e9 puisqu\u2019il est bien connu que les stress hydriques ont \u00e9t\u00e9 identifi\u00e9s comme des facteurs d\u00e9clenchants de certains d\u00e9p\u00e9rissements forestiers et que les sc\u00e9narios d\u2019\u00e9volution climatique tendent \u00e0 pr\u00e9voir une augmentation des fr\u00e9quences des \u00e9pisodes secs et chauds. On y apprend que plus de 90 % de l\u2019eau transport\u00e9e jusqu\u2019aux feuilles y est simplement \u00e9vapor\u00e9e avec comme cons\u00e9quence, non n\u00e9gligeable cependant, de limiter l\u2019\u00e9chauffement de celles-ci. \u00c0 l\u2019\u00e9chelle d\u2019une saison de v\u00e9g\u00e9tation et d\u2019une for\u00eat enti\u00e8re, c\u2019est 80 % de l\u2019eau qui retourne sous forme de vapeur \u00e0 l\u2019atmosph\u00e8re. Outre les mesures prises, c\u2019est surtout leur utilisation \u00e0 travers des mod\u00e8les qui s\u2019av\u00e8re int\u00e9ressante. En effet, il est possible, sur base de quelques donn\u00e9es climatiques, de pr\u00e9dire (ann\u00e9es futures) ou d\u2019expliquer (ann\u00e9es ant\u00e9rieures) les variations de la r\u00e9serve en eau du sol d\u2019un peuplement.<\/p>","protected":false},"excerpt":{"rendered":"
