This book summarizes the results of 3 years of agricultural and forestry reconstructive efforts and applied research conducted directly in the affected areas of Fukushima following the Great East Japan Earthquake. It describes fast and effective revival methods and technologies from tsunami and radiation damages, demonstrated through the collaborative efforts of researchers, students, local farmers, forest owners, and municipalities gathered under the Tokyo University of Agriculture East Japan Assistance Project. Consisting of four parts, the first part of the book provides an overview of the damage and measures taken to overcome them by the local municipalities and the Tokyo University of Agriculture. The second part presents data and results of agricultural recovery from the tsunami—for example, monitoring systems, reconstruction models, and convenient, low-cost methods developed for the restoration of tsunami-damaged paddy fields. The third part focuses on recovery from radiation-contaminated farmlands and forests and consequent reputational damages. Included are various primary data obtained from field experiments and surveys, studies on the mechanism of contamination, and the results of radical monitoring, decontamination, and restoration techniques performed at this site. The final part is a collection of reflections of local farmers, forest owners, and students who participated in the project. The academic trials and errors recorded in this book are an invaluable contribution to disaster management and recovery processes. It is written for a wide audience, not limited to researchers and students, but also for government and state officials, municipalities, agricultural cooperative staff members, and farmers.
While not all natural disasters can be avoided, their impact on a population can be mitigated through effective planning and preparedness. These are the lessons to be learned from Japan's own megadisaster: the Great East Japan Earthquake of 2011, the fi rst disaster ever recorded that included an earthquake, a tsunami, a nuclear power plant accident, a power supply failure, and a large-scale disruption of supply chains. It is a sad fact that poor communities are often hardest hit and take the longest to recover from disaster. Disaster risk management (DRM) should therefore be taken into account as a major development challenge, and countries must shift from a tradition of response to a culture of prevention and resilience. Learning from Megadisasters: Lessons from the Great East Japan Earthquake consolidates a set of 36 Knowledge Notes, research results of a joint study undertaken by the Government of Japan and the World Bank. These notes highlight key lessons learned in seven DRM thematic clusters—structural measures; nonstructural measures; emergency response; reconstruction planning; hazard and risk information and decision making; the economics of disaster risk, risk management, and risk fi nancing; and recovery and relocation. Aimed at sharing Japanese cutting-edge knowledge with practitioners and decision makers, this book provides valuable guidance to other disaster-prone countries for mainstreaming DRM in their development policies and weathering their own natural disasters.
This book is related to disaster risk reduction in agriculture particularly under changing climate. Climate change refers to significant, long-term changes in the global climate. There is unequivocal evidence that Earth is warming at an unprecedented rate. Human activity is the principal cause. The planets average surface temperature has risen to about 1oC since the late 19th century and most of the warming occurred in the past 40 years. The years 2016 and 2020 are tied for the warmest year on the record. Similarly, other evidence of rapid climate change includes warming of oceans, shrinking of ice sheets, retreating glaciers, decreasing snow cover, rising of sea level, declining artic sea ice, increased frequency of extreme events, ocean acidification and loss of biodiversity. Hence, climate change impacts, both extreme weather and slow-onset events, have impacted several sectors of the national economies and activities, in particular agriculture and food production, augmented by other challenges be it geopolitical, cost of finance or supply chain related, and in a time of increased food insecurity. Without CO2 fertilization, effective adaptation, and genetic improvement, each degree-Celsius increase in global mean temperature would, on average, reduce global yields of wheat by 6.0%, rice by 3.2%, maize by 7.4%, and soybean by 3.1%. Hence this book is useful as a study material to teach in the field of agriculture and climate change. The book is useful for instructors and postgraduate as well as undergraduate students involved in the study of climate change. The book also provide guidance to multiple stakeholders to design mitigation and adaptation efforts to climate change and ensure food security in the developing world.
This open access book presents the findings from on-site research into radioactive cesium contamination in various agricultural systems affected by the Fukushima Daiichi Nuclear Power Plant accident in March 2011. This third volume in the series reports on studies undertaken at contaminated sites such as farmland, forests, and marine and freshwater environments, with a particular focus on livestock, wild plants and mushrooms, crops, and marine products in those environments. It also provides additional data collected in the subsequent years to show how the radioactivity levels in agricultural products and their growing environments have changed with time and the route by which radioactive materials entered agricultural products as well as their movement between different components (e.g., soil, water, and trees) within an environmental system (e.g., forests). The book covers various topics, including radioactivity testing of food products; decontamination trials for rice and livestock production; the state of contamination in, trees, mushrooms, and timber; the dynamics of radioactivity distribution in paddy fields and upland forests; damage incurred by the forestry and fishery industries; and the change in consumers’ attitudes. Chapter 19 introduces a real-time radioisotope imaging system, a pioneering technique to visualize the movement of cesium in soil and in plants. This is the only book to provide systematic data on the actual change of radioactivity, and as such is of great value to all researchers who wish to understand the effect of radioactive fallout on agriculture. In addition, it helps the general public to better understand the issues of radio-contamination in the environment. The project is ongoing; the research groups from the Graduate School of Agricultural and Life Sciences of The University of Tokyo continue their work in the field to further evaluate the long-term effects of the Fukushima accident.
Agriculture is particularly vulnerable to extreme climatic events, yet knowledge is lacking regarding the precise extent of losses caused by disasters in the sector. This analysis aims to provide the most extensive estimation of disaster losses (including non-hydrometeorological disasters) in the agricultural sector worldwide by including data from 197 countries and 186 commodities from 1991 to 2021, accounting for 12 000 time series and about 9 000 disaster events. The disaster events data is drawn from the Emergency Events Database (EM-DAT) and the records of yields, productions, cultivated areas, and prices for all commodities over the period from FAOSTAT.
The volume brings together a stellar group of contributors who examine the social capital thesis by means of four different approaches: theoretical, historical, comparative, and empirical. In the end, this book will serve to answer two fundamental questions which have hitherto been neglected: What can a gendered analysis tell us about social capital? And what can social capital tell us about women and politics?
This book focuses on the ecological impacts of the Great East Japan Earthquake and resulting tsunamis, a rare and extremely large disturbance event, on various coastal ecosystems in Japan’s Tohoku area, including sub-tidal and tidal animal communities, sand dune plant communities and coastal forests. The studies presented here describe not only how species and populations in these ecosystems were disturbed by the earthquake and tsunamis, but also how the communities have responded to the event and what types of anthropogenic activities will hamper their recovery processes. In the ecological sciences, it is often argued that large disturbances are critical to shaping community structures and biodiversity in local and regional habitats. However, our understanding of these roles remains limited, simply because there have been few opportunities to examine and address the ecological impacts of large disturbance events. The scale of the 2011 Great East Japan Earthquake makes it one of the largest hazards in the past 1000 years. Thus, this book provides a unique opportunity to advance our understanding of the ecological impacts of large and rare disturbances and the implications of these events in the conservation and management of coastal ecosystems. Following an outline of the Great East Japan Earthquake, the book’s content is divided into two major parts. Part I reports on studies examining the ecological impacts of the tsunamis on sub-tidal and tidal animal communities, while Part II focuses on terrestrial plant communities in Japan’s coastal Tohoku area. This book will benefit all scientists interested in the ecological impacts of large disturbances on aquatic and terrestrial ecosystems in general, and especially those who are interested in the ecological management of coastal ecosystems and Ecosystem based Disaster Risk Reduction (EcoDRR).
On top of a decade of exacerbated disaster loss, exceptional global heat, retreating ice and rising sea levels, humanity and our food security face a range of new and unprecedented hazards, such as megafires, extreme weather events, desert locust swarms of magnitudes previously unseen, and the COVID-19 pandemic. Agriculture underpins the livelihoods of over 2.5 billion people – most of them in low-income developing countries – and remains a key driver of development. At no other point in history has agriculture been faced with such an array of familiar and unfamiliar risks, interacting in a hyperconnected world and a precipitously changing landscape. And agriculture continues to absorb a disproportionate share of the damage and loss wrought by disasters. Their growing frequency and intensity, along with the systemic nature of risk, are upending people’s lives, devastating livelihoods, and jeopardizing our entire food system. This report makes a powerful case for investing in resilience and disaster risk reduction – especially data gathering and analysis for evidence informed action – to ensure agriculture’s crucial role in achieving the future we want.
​This book examines the impacts of radionuclides released from the 2011 Fukushima Daiichi Nuclear Power Plant (FDNPP) accident on inland aquatic environments. The focus is on the dynamics of radiocesium in inland aquatic environments. The book comprises three parts: migration behavior of radiocesium in river and lake environment, accumulation of radiocesium into organisms in freshwater, and integrated environmental analysis in a lake system and a forest-freshwater system. Many studies on the dynamics of radionuclides have been published after the FDNPP accident, especially of radiocesium (134Cs 137Cs) in land and marine environment. The key features of this book are the new data of freshwater environment including transport of radionuclides in river and lake watershed, and accumulation of radiocesium in freshwater fishes and insects. Another feature of this book is that it summarizes the dataset of a model lake, Lake Akagi-Onuma, from geochemical and biological approaches. Readers will learn the actual dispersion behavior of radionuclides released from the Fukushima accident and their impacts on freshwater environments since the accident in 2011. The book presents valuable information for assessing the impacts of the FDNPP accident on ecosystem and human health, which are also useful in developing countermeasures for similar accidents and environmental contaminations.
This book covers the restoration and reconstruction process and activities undertaken in Japan in the first five years since the 2011 Earthquake and Tsunami – a period widely considered to be the most intensive reconstruction phase within the 10-year restoration plan drawn up by the Japanese Government. The respective chapters explore technical, scientific, social and non-scientific (policy-related) aspects, including: reconstruction and restoration policies, infrastructure and designs for tsunami coastal defence, resilient urban areas and affected communities, housing and relocation schemes, disaster mitigation and evacuation measures, reactivation of the economy, revitalization of fisheries and coastal agriculture, and industry and tourism. The book also illustrates some of the achievements and failures in a broad range of projects and initiatives intended to address the above-mentioned issues, making it particularly relevant for experts, decision makers, students and other interested scholars.
