Track 5-1-1: Global Role of Grassland Management in Mitigating Climate Change Effects on the Environment and Human Welfare
Description
The Great East Japan Earthquake on 11 March 2011, followed by tsunami, incurred the accident of the Fukushima Dai-Ichi Nuclear Power Station (NPS). The radioactive fallout was dispersed by wind and deposited in large part of eastern Japan by rainfall or snowfall after the accident (Chino et al., 2011; Katata et al., 2012; Terada et al., 2012). That caused extensive pollution by radioactive cesium (Cs) (the sum of 134Cs and 137Cs) in agricultural lands (MEXT, 2011) including permanent pastures and meadows. In mountainous areas, it can be thought that radioactive Cs migrated from convex to concave regions by snow melting and rain water, therefore radioactive pollution is higher on concave areas than convex areas. In this study, air dose rate and radioactive Cs concentration in aboveground part of plant were monitored for three years on mountainous grazing pastures in north-eastern region of Japan.
