  abstract = {{P}>{S}oil degradation processes have dramatically increased in their extent and intensity over the last decades. {P}rogressively, actions have been taken in order to evaluate and reduce the major threats that have already wreaked havoc on soil conditions. {E}fficient and standardized monitoring of soil conditions is thus required but soil quality research is facing an important technological challenge because of the number of properties involved in soil quality. {T}he objective of the present review is to examine critically the suitability of near-infrared reflectance spectroscopy ({NIRS}) as a tool for soil quality assessment. {W}e first detail the soil quality-related parameters (chemical, physical and biological) that can be predicted with {NIRS} through laboratory measurements. {T}he ability of imaging {NIRS} (airborne or satellite) for mapping a minimum data set of soil quality is also discussed. {T}hen we review the most recent research using soil reflectance spectra as an integrated measure of soil quality, from global site classification to the prediction of specific soil quality indices. {W}e conclude that imaging {NIRS} enables the direct mapping of some soil properties and soil threats, but that further developments to solve several technological limitations identified are needed before it can be used for soil quality assessment. {T}he robustness of laboratory {NIRS} for soil quality assessment allows its implementation in soil monitoring networks. {H}owever, its routine use requires the development of international soil spectral libraries that should become a priority for soil quality research.{R}esume {E}valuation et surveillance de la qualite des sols par spectroscopie proche infrarouge ({SPIR}) {L}es processus de degradation des sols ont fortement augmente au cours des dernieres decennies. {D}es mesures sont progressivement mises en place afin d'evaluer et de limiter l'impact des principales menaces qui ont dej provoque une diminution preoccupante de la qualite des sols. {D}es methodes efficaces et standardisees de suivi de la qualite des sols sont donc indispensables, mais les nombreuses proprietes impliquees dans la qualite des sols compliquent son evaluation rigoureuse. {L}'objectif de cette revue est d'examiner le potentiel de la spectroscopie proche infrarouge ({SPIR}) comme outil rapide de caracterisation de la qualite des sols. {N}ous dressons d'abord l'inventaire des proprietes du sol liees sa qualite qui sont predictibles par des mesures {SPIR} en laboratoire. {L}e potentiel de l'imagerie embarquee {SPIR} (satellite, avion) est egalement aborde. {N}ous realisons ensuite une synthese des applications utilisant la reflectance spectrale des sols comme mesure integree de leur qualite, depuis la classification de sites selon leur etat de degradation jusqu' la prediction d'indices specifiques de qualite du sol. {N}ous concluons que l'imagerie {SPIR} permet de cartographier quelques proprietes et menaces pesant sur les sols, mais les limites technologiques relevees exigent d'importants developpements pour en faire un outil robuste d'evaluation de la qualite des sols. {L}a fiabilite de la technique {SPIR} par mesures en laboratoire permet sa mise en oeuvre rapide dans les reseaux de mesures de la qualite des sols. {T}outefois, son utilisation en routine necessitera le developpement de librairies spectrales internationales, qui devrait constituer une des priorites de recherche sur la qualite des sols.},
