The Fukushima Dai-ichi Nuclear Power Plant (FDNPP) accident in March 2011 resulted in the contamination of Japanese landscapes with radioactive fallout. The objective of this review is to provide an overview of the decontamination strategies and their potential effectiveness in Japan. Overall, we believe it is important to synthesize the remediation lessons learnt following the FDNPP nuclear accident, which could be fundamental if a similar catastrophe occurred somewhere on Earth in the future.

Global warming leads to increased mineralization of soil organic matter, inducing a positive climate-carbon cycle feedback loop. Loss of organic matter can be associated with loss of soil structure. Here we use a strong geothermal gradient to investigate soil warming effects on soil organic matter and structural parameters in subarctic forest and grassland soils. Strong depletion of organic matter caused a collapse of aggregates highlighting the potential impact of warming on soil functions.

Soil stores a lot of carbon and slows down global warming. The capacity of soil to store carbon is affected by many factors and we don't clearly know how they work. We studied how rainfall change affects soil carbon storage related to soil structure in the Andes. We found soil structure is not important. How rainfall change affects soil carbon storage is dependent on rocks under the soil. The results indicate the rocks under the soil are important for soil to store carbon against global warming.
