After 10 years of the Fukushima Nuclear Accident, Japan decided on 13 April 2021 to release the nuclear wastewater into the Pacific Ocean. It is apparent that Japan has chosen the most cost-efficient way to deal with the contaminated water, however, great opposition and concerns have been aroused internationally due to the harmful ecotoxicological features of radioactive materials. Here we analyze the ecological impacts caused by the nuclear accident and the potential impacts of releasing the nuclear wastewater into the ocean.
The Sendai Framework for Disaster Risk Reduction (SFDRR) has helped to reduce global disaster risk, but there has been a lack of progress in disaster risk reduction (DRR) for people living in fragile and conflict affected contexts (FCAC). Given the mounting evidence that DRR cannot be implemented through conventional approaches in FCAC, serious efforts must be made to understand how to meet SFDRR's goals.
A possibility of developing an environmental-friendly photovoltaic/thermal (PV/T) solar panel, which can shut high temperature radiation within a panel box, was experimentally confirmed. The panel has a decompression-boiling heat collector, which can absorb heat from the PV module and can keep the air and the cover glass inside the panel box at lower temperature by using lower boiling temperature of working fluid under vacuum condition. The panel also has an emboss-processed cover glass, which can totally reflect the high temperature heat radiation from the PV module within the panel box.
The UN has adopted the Sendai Framework for Disaster Risk Reduction (2015–2030; SFDRR) in March 2015 and the member countries agreed to shift from disaster management to disaster risk management. The SFDRR is in line with the UN Sustainable Development Goals (SDGs; September 2015). In 2016, the UNISDR together with partner organizations has prepared roadmap for mainstreaming Science and Technology in SFDRR. Out of four priority areas, this paper focuses on the appraisal of challenges in SFDRR priority 1 “understanding disaster risk” through the lens of science, technology and innovations.
The “build back better” (BBB) approach to disaster recovery was first introduced in 2006 by the United Nations Secretary-General's Special Envoy for Tsunami Recovery, former US President William Clinton. In 2015, BBB became the second half of Priority 4 of the Sendai Framework for Disaster Risk Reduction 2015–2030, in recognition of its widespread use and adoption among disaster risk management practitioners, policy-makers, and researchers.
In spite of the growing attention towards the overall quality of Marine Protected Areas (MPAs), most empirical studies so far have narrowly focused their assessments on specific natural or social features and governing structures. In response, this study analyzed multi-use MPAs in the eelgrass restoration site in Hinase, Okayama, Japan in their environmental, economic and social dimensions. Considering changes in time and space as well as internal and external influences, the study faced many difficulties in dealing with the dynamics of MPA environments.
