Assessing Crop Productivity in Decontaminated Farmland in Fukushima Using Micro-Satellite Venμs and Hyperspectral Sensing

摘要

Farmland in the Fukushima region of Japan experienced serious radioactive contamination as a result of the Fukushima Nuclear Power Plant disaster in 2011. A large number of farm-fields have been decontaminated by replacing the top surface soil with non-contaminated soil. This preliminary study investigated the potential of high spatial- and temporal-resolution micro-satellite Venμs and ground-based hyperspectral sensing techniques for assessment of soil fertility and rice productivity in the region to assist the agricultural recovery. Results suggested that these variables would be estimated in a regional scale by remote sensing approaches.
