“…Large differences within a small spatial scale were also reported in the impact assessment of the 2004 tsunami along the Andaman Sea coast of Thailand (Whanpetch et al 2010). Similar tsunami impact assessments have been ongoing by various marine scientists and fisheries researchers who have been studying the areas since before the disaster happened (Urabe et al 2013;Takami et al 2013). Mate analysis incorporating these individual studies across a large spatial extent and diverse environmental gradients provide promising ways to understand general characteristics of how the tsunami's impacts and subsequent recovery processes varied.…”

The primary goal of the 60th anniversary symposium of the Ecological Society of Japan (ESJ) was to re‐examine the role of the Society. The first of five lectures, “Development of Long‐term Ecological Research in Japan,” discussed the increasingly important role of long‐term and networked research studies. Ecological research in Asia faces many challenges, because Asia features natural and anthropogenic landscapes with highly diverse ecosystems. “Developing Strategies of the Ecological Society of Japan for Worldwide Societies of Ecology with Special Reference to Strategies for Asia” emphasized the role of ESJ in promoting ecological research and outreach in Asia. Ecosystem sustainability is a key issue in both the theory and practice of ecosystem management. A framework concept of an environmental and biodiversity cycle was proposed in the session “Linking Community and Ecosystem Dynamics” for understanding the mechanisms driving the sustainability of ecosystems. Ecosystem services are essential aspects of land use and conservation planning and management. “Integrating Models of Ecosystem Services and Land Use Changes” reviewed recently‐developed models that simulate patterns of land‐use change and analyze its effects on ecosystem services and also recommended future directions for collaboration among researchers. “Disaster Resilience and Coastal Ecology” highlighted the contributions of ecologists to evaluating the resilience of damaged coastal ecosystems and provided sound proposals to local communities and governments for rehabilitation plans. The past achievements and future directions of ESJ were discussed by the panelists and the audience in “Past and Future of the Ecological Society of Japan.”

“…The March 2011 disasters have had enormous environmental impacts [Kontar at al., 2014;Ministry of Environment, 2017;NASA, 2011;Urabe et al, 2013;UNSCEAR, 2014;WWF, 2013].…”

“…For instance, in Mangokuura lagoon, Ishinomaki City, the ground was seen to have subsided by about 0.9-1.5 meters, becoming muddy as sludge accumulated, distribution area of the Zostera was drastically reduced, and their population growing from the coast up to about 100 meters out at sea was exterminated. The study of Sendai Bay and the Sanriku Ria coast showed that 30-80% of taxa indigenously inhabiting intertidal flats disappeared after the tsunami [Urabe et al, 2013]. Among animal types, endobenthic and sessile epibenthic animals were more vulnerable to the tsunami than mobile epibenthic animals like shore crabs and snails.…”

On March 11, 2011 the strongest ever recorded in Japan earthquake occurred, also known as the Great East Japan Earthquake, which triggered a powerful tsunami and caused a nuclear accident in one of the world biggest nuclear power stations -Fukushima Daichi. More than six years after the triple disaster the overall impacts on Japanese agri-food chains is far from being completely due to the scale of the disasters and the number of affected agents, the effects' multiplicities, spillovers, and long time horizon, the constant evolution of the nuclear crisis, the lack of "full" information and models of analysis, etc. This paper presents updates on the impacts of the March 2011 earthquake, tsunami and Fukushima nuclear accident in Japan on country's agriculture and food sector. First, disaster events and their effects is outlined. Second, impact on farms and agricultural resources is estimated. Third, impact on food industries is assessed. Next, extend of radioactive contamination of agri-food products is presented and effects on markets, consumers and international trade evaluated. Chapter summarises responses of different agents, assesses progress and challenges in post-disaster recovery and reconstruction, and withdraw lessons from the Japanese experiences.

“…Many studies conducted after the tsunami have focused on the ecological impacts caused by the 2011 tsunami and have demonstrated drastic changes in species composition and abundance of fish and benthic communities at various sites (Masuda 2012(Masuda , 2013Miura et al 2012;Nakayama et al 2013;Seike et al 2013;Urabe et al 2013). The tsunami similarly affected riverine macroinvertebrate communities far upstream from the river mouth during inundation (Watanabe et al 2014).…”

Immediate impact of the tsunami associated with the 2011 Great East Japan Earthquake on the Plecoglossus altivelis altivelis population from the Sanriku coast of northern Japan

The huge tsunami associated with the 2011 Great East Japan Earthquake severely impacted the ecosystems on the Sanriku coast of Japan. The life history traits of ayu, Plecoglossus altivelis altivelis, which have a one-year amphidromous life history, were investigated by otolith analyses in two rivers of the Sanriku coast just after the tsunami compared with results before the tsunami to reveal the immediate impact of the tsunami. Hatching date compositions differed between the upstream migrants before and after the tsunami. The migrants after the tsunami were solely composed of fish hatched during October and November, whereas the migrants before the tsunami were mostly composed of fish hatched in September. Discrepancies between the hatching dates of the migrants and drifting larvae (hatched larvae) indicate that selective mortality of early-hatched fish occurred during the tsunami. Differences in otolith Sr:Ca ratios between upstream migrants before and after the tsunami suggest that fish surviving the tsunami inhabited saline water and earlyhatched fish that inhabited the estuary decreased selectively in number because of the severe erosion around the river mouth. The oceanic growth period shortened in accordance with the change in hatching date. These results show that the tsunami drastically altered the ecology of P. altivelis altivelis on the Sanriku coast.
