This paper discusses the need for monitoring the state and evolution of arid and semi-arid environments, and compares the specific contributions of in situ and satellite-based techniques. The role of physically-based models in the quantitative interpretation of the measurement is stressed, and a strategy is proposed for the systematic exploitation of space technologies.
