The objectives of this article are to briefly review the existing sources of remote sensing data and their potential to detect drought damage to review the remote sensing applications and studies carried out during the last two decades aiming at detecting and quantifying disturbances caused by various stress factors and especially those causing effects similar to drought to explore the possibility to use some of the different available systems for setting up a strategy more adapted to monitoring of drought effects in forests. drought forest remote sensing satellite Résumé - Contribution de la télédétection à revaluation des effets de la sécheresse sur les écosystèmes forestiers. Grâce à leurs capacités de surveillance continue les satellites d observation de la Terre pourraient s avérer utiles pour l évaluation des effets de la sécheresse sur les écosystèmes forestiers.
