The main focus of my research lies in the modelling of soil erosion by wind and water in low rainfall cropping regions using remotely sensed data and Geographic Information Systems (GIS). The application of remote sensing techniques and modern satellite data can facilitate the evaluation of natural processes such as soil erosion over very large regions (e.g. 160,000 km2). Indeed, higher resolution datasets are now available, with high temporal imaging capabilities, ranging from daily to every 30 minutes. This research project therefore aims at combining and comparing some of these products and select the best combination to assess soil losses linked to changes in land management and climate conditions.
