This year is the 35th anniversary of the Chernobyl and the 10th anniversary of the Fukushima nuclear power plant accidents. Forest is the key ecosystem in the contaminated areas. The radioactive contamination affects everything in the landscape. The rural landscape with forests and arable lands around Fukushima have been formed through close interactions between nature (forests) and human activities, known as SATOYAMA landscapes in Japanese. This webinar was organized as a collaboration between two working parties of landscape ecology and radioecology. This webinar aims to look at the two nuclear disasters from various angles, particularly from a landscape perspective.
