This paper explores the use of a multi-sensor approach to monitor semi-arid areas of Vietnam, and represents the initial findings of a PhD project commenced in October 2003. Multitemporal data from optical systems, including ASTER and MODIS, have been employed to observe soil and vegetation at both large and small scale, and the thermal band of ASTER used to extract surface temperature data. ENVISAT ASAR (Advance Synthetic Aperture Radar) was used to estimate soil moisture using a data fusion approach. The relationship between vegetation density, soil moisture, and surface temperature, and the role of these parameters in the desertification process are under investigation. The final phase of the project will be to develop a desertification index based on three parameters: surface temperature, vegetation cover and soil moisture.
