“…Moreover, root distribution is limited in surface soil. Hoshino et al (2015) confirmed that the radiocesium TF of soybean was significantly decreased by tillage. MAFF (2014c, 2014d) recommended deep tillage as a countermeasure to reduce radiocesium concentration in soybean and buckwheat.…”

Five years have passed since the accident at Tokyo Electric Power Company Fukushima Daiichi Nuclear Power Station that was triggered by the Great East Japan Earthquake on 11 March 2011. Severe damage to agriculture and the environment is still of great concern in Japanese society. We review the contamination status of agricultural products and soils, decontamination efforts and countermeasures to reduce radiocesium concentration in soil and crops, as well as the responses of Japanese ministries. Since rice is an important staple food for Japanese, the impact of radiocesium on rice (Oryza sativa L.) and paddy fields has been extensively investigated since the accident, and, therefore, issues concerning rice receive considerable attention in this review.

“…Harada et al (2014) [26] demonstrated that the effects of using contaminated farm yard manure on the concentration of radioactive Cs found in crops depend not only on the contamination level, but also on factors, such as soil exchangeable K 2 O content. Furthermore, Hoshino et al (2015) [52] reported that the ecological behavior of radioactive Cs is influenced by the amount of clay minerals present in the soil. Thus, the low radioactive Cs concentrations found in Komatsuna plants in this study could be related to these two effects.…”

Abstract:Following the Fukushima Daiichi Nuclear Power Plant (FDNPP) accident, the forests in the Fukushima area were highly contaminated with radiocesium ( 137 Cs and 134 Cs). Therefore, there is a need to develop strategies for remediation of the contaminated forests. We assessed changes in radioactive cesium ( 134 Cs and 137 Cs) contamination and nutrient status in composts derived from wood chip, bamboo leaf and bamboo powder using rice bran and wheat meal as sub-materials. Changes in soil properties and Komatsuna (Brassica rapa var. perviridis) growth were also investigated due the application of composts and initial materials at 0, 2.5, 5 and 10 kg·m −2 input levels. Mixing of sub-materials significantly reduced the concentration of radioactive Cs and improved compost quality. The effectiveness of three composts on soil quality improvement varied depending on their types and rates of applications. Amendments of bamboo leaf composts at 10 kg·m −2 resulted in the significantly highest soil inorganic N, available P and exchangeable K contents. Amendments of final composts also enhanced Komatsuna growth. Furthermore, radioactive Cs contaminations of the Komatsuna plants grown in these composts were below 0.1 Bq·kg −1 . This study may help to remediate the forests contaminated with radiocesium in the Fukushima area while improving the soil organic matter content to enhance soil sustainability.

“…Tillage resulted in 2‐ to 4‐fold reductions in Cs transfer factors in the first year after the Chernobyl accident, whereas skim and burial ploughing resulted in 8‐ to 16‐fold reductions. In Fukushima, Cs transfer factors after deep ploughing were reduced by only 2‐ to 3‐fold (IAEA ; Hoshino et al ). Placing a fertile topsoil layer below the rooting zone or complete mixing of the soil horizon was suitable for the fertile soils of the Fukushima affected areas, but for the light‐textured soils in most of the Chernobyl affected areas, these tillage techniques impaired soil fertility by removing or diluting the thin fertile top layer.…”

The options adopted for recovery of agricultural land after the Chernobyl and Fukushima accidents are compared by examining their technical and socio-economic aspects. The analysis highlights commonalities such as the implementation of tillage and other types of countermeasures and differences in approach, such as preferences for topsoil removal in Fukushima and the application of K fertilizers in Chernobyl. This analysis shows that the recovery approach needs to be context-specific to best suit the physical, social, and political environment. The complex nature of the decision problem calls for a formal process for engaging stakeholders and the development of adequate decision support tools.
