    Although the concept of green infrastructure cobenefits is widely recognized, few studies document how transdisciplinary governance mechanisms sustain multipurpose outcomes over several decades. This paper examines how sustained collaborative governance enabled the Asahata Reservoir in Shizuoka City, Japan,
    to transition from conventional flood infrastructure to multipurpose green infrastructure, providing environmental, social, and cultural benefits over four decades. Using project documents, government reports, and field visits, the study analyzes the governance
    arrangements and institutional mechanisms that maintained stakeholder engagement and achieved measurable outcomes in flood protection, biodiversity conservation, and social inclusion. The findings show that the transdisciplinary governance platform, the Nature Restoration Council, established in 2004, effectively coordinated multiple stakeholders, including government agencies, civil society organizations, health care
    institutions, and community groups, to support integrated management. The reservoir has maintained its flood storage capacity while supporting 214 bird species and 21 endangered plant species and providing vocational training and therapeutic programs for people with disabilities and older adults. This long-term collaborative approach created complementary relationships among flood protection, ecological restoration, and social services. The case study advances theoretical understanding of transdisciplinary governance by presenting concrete institutional mechanisms for sustained stakeholder coordination in managing multipurpose infrastructure. It offers policymakers transferable lessons for operationalizing collaborative approaches: establish stable multi-stakeholder platforms early in project development, combine public funding with community contributions to support long-term sustainability, and design adaptive management systems that address changing urban needs. The find
    ings contribute to global discussions on aligning disaster risk reduction, climate adaptation, and social inclusion through innovative governance of green infrastructure

  • Short-term optimization, long-term vulnerability: system-level economics of flood protection and urban development in the Shinanogawa River Reviewed

    Flood protection infrastructure can paradoxically increase vulnerability through the ‘levee effect' or the ‘safe development paradox'. In some cases, protection can reduce the perceived risk of flooding, leading to the intensive development of floodplains. This may necessitate additional investment, as short-term rational optimization can create long-term vulnerabilities through path-dependent processes that are difficult to reverse. However, the empirical evidence is limited. This study uses the Shinanogawa River Basin in Japan as a case study to examine this feedback cycle and the dynamics of the coupled human–water system over the centuries. The study reconstructs economic analyses to provide a systematic, long-term, river-basin-wide examination. This retrospective analysis aims to extract lessons that can be applied to current and future flood protection and development planning in the context of climate change and evolving social values, rather than criticizing past decisions in hindsight. The completion of the Okozu Diversion Channel in 1924 reduced flood risk in Nigata City, enabling river reclamation in the 1930s and 1940s. While this project contributed to the development of Nigata City, it also narrowed the river, reducing its flood capacity. Although these reclamation projects appeared profitable at a project level, they created hidden liabilities, necessitating the construction of the Sekiya Diversion Channel in 1972. Together, these interventions resulted in a net system loss of 12 trillion JPY, or 80 billion USD, at maximum. System-level analysis reveals reclamation created a hidden liability requiring compensatory infrastructure costing 365 billion JPY, or 2.4 billion USD (2015 prices, 4% discount rate). This analysis demonstrates how conventional project-level cost-benefit analysis can mask system-wide implications and liabilities. The study traced interventions and social responses, revealing that the temporal mismatch between human decision-making timeframes (years to decades) and the frequency of hydrological events (decades to centuries) was the driving force behind this dynamic. Flood management strategies must consider the long-term by incorporating the uncertainty caused by climate change and the changing environmental and cultural values of water.

    Social infrastructure plays a critical role in disaster resilience through enhancing social capital. However, empirical evidence linking community-based preparedness activities at social infrastructure to disaster outcomes remains limited. This study examines how Kominkan (community learning centers) in Japan function as social infrastructure to strengthen community disaster resilience through using the 2024 Noto Peninsula earthquake as a case study. The disaster claimed 636 lives and damaged more than 165,000 homes. Qualitative research methods, including site visits to five Kominkan and document analysis, were employed. Communities with established disaster preparedness programs integrated into Kominkan activities demonstrated emergency response capabilities. It was found that pre-disaster preparedness activities translated directly into effective emergency response and supported recovery efforts. Kominkan leveraged pre-existing social networks, leadership, and local knowledge to coordinate rescue operations, manage evacuation shelters, and maintain social cohesion during recovery. The study found that creative integration of disaster preparedness into recreational and cultural activities, such as sports festivals and newsletters, sustained community engagement. Furthermore, embedded local knowledge enabled rapid, context-appropriate decision-making. The multi-functional nature of Kominkan—serving educational and cultural purposes during normal times while maintaining disaster readiness—proved essential.

    Water resources management needs to be strengthened to address increasing
    flood and drought risks exacerbated by climate change and socio-economic development.
    This requires effective water governance mechanisms that can reduce vulnerability in disasters
    while managing complex stakeholder relationships. This paper analyzes the evolution
    of water governance in Japan over more than half a century, examining how the country
    transformed from a centralized, top-down approach to a more collaborative model of water
    management. Through an analysis of three significant water infrastructure projects, this
    study identifies key drivers of governance change and evaluates the effectiveness of various
    stakeholder engagement mechanisms. The findings reveal how catalytic events prompted
    institutional innovations in addressing social impacts, environmental concerns, and climate
    resilience. Challenges remain in balancing diverse interests, managing implementation
    timeframes, and incorporating climate change uncertainties into decision-making processes.
    This paper offers important lessons for developing countries working to strengthen their
    water governance frameworks, particularly regarding stakeholder engagement, social impact
    mitigation, and the development of flexible institutional arrangements that can adapt
    to emerging climate risks. This research contributes to governance theory by demonstrating
    how institutional evolution occurs through the interaction of formal mechanisms and
    informal processes in response to changing social, environmental, and climatic conditions.

    The ongoing war in Ukraine poses an uncertain future, highlighting the need to prioritize reconstruction efforts even before the war ends. Japan’s recovery mechanisms have developed based on the experiences and lessons learned from natural disasters such as the Great Kanto Earthquake in 1923 and from war damage by World War II. This study aims to draw practical insights and lessons from the 2011 Great East Japan Earthquake for Ukraine’s postwar recovery and help achieve rapid and high-quality results. This study reviews the literature, policy documents, and reports on recovery from the disaster. It was found that streamlining environmental impact assessments, land use regulations, and land acquisition could accelerate recovery. Engaging the private sector promoted the reconstruction of critical infrastructure and housing projects. This Japanese case study highlights the importance of ensuring sustained commitment and avoiding setbacks in the recovery process by establishing legislative, planning, and institutional frameworks, as well as financial mechanisms. Protecting human health is paramount, even if more resources are needed to manage hazardous materials. Applying these valuable lessons to Ukraine requires careful consideration, including leveraging foreign investments to supplement limited domestic resources and establishing effective governance structures that promote transparency, accountability, and coordination.

    Drones, unmanned aerial systems, are of growing interest to organizations involved in disaster risk reduction, particularly in post-disaster emergency response. Despite the potential benefits of drones, their use is not well established and practical challenges need to be understood. This study examines the role of drones in disaster management by analyzing various applications of drones in response to the Noto Peninsula earthquake in January 2024. Drones were used on the ground in a variety of new ways, including transport of emergency supplies, restore of cellphone communications, and inspect on damaged facilities. Several issues were identified, including the need to incorporate drone capabilities into disaster management plans, develop appropriate laws and regulations, establish public-private coordination mechanisms, address technological limitations due to advances in technology, and implement training programs specifically for drone operators. Collaboration among government agencies, private organizations, and industry associations in disaster response highlighted the importance of fostering partnerships and mobilizing collective expertise in disaster management. The study concludes by highlighting the important role that drones can play in enhancing emergency response efforts and mitigating the impact of future disasters.

    Asia, a rapidly emerging global economic power, is vulnerable to natural disasters. Its annualized flood-related losses, amounting to 53 billion USD and approximately 16,000 human lives, are expected to increase with further climate change. Several international organizations have recommended increasing investment in disaster risk reduction (DRR) and climate change adaptation (CCA). Developing Asian economies’ investment of 33.6 billion USD (0.21% of their GDP) in flood protection in 2015 is projected to reach 100 billion USD annually by 2030. Official development assistance (ODA) in DRR—5 billion USD/year from 1991 to 2010—increased by 2.6 times to 13.3 billion USD/year from 2011 to 2020. Simultaneously, investment in risk prevention or reduction decreased from 680 to 550 million USD/year (a decrease from 12.7 to 4.1% as the share in DRR assistance). This book collates the existing data, research findings, conceptual works of the scholars and senior officials of disaster management organizations who directly manage or investigate natural disasters in the Asia-Pacific, and practical cases of investment in DRR and CCA. This chapter examines the international initiatives for promoting investment in DRR and CCA and the current and projected funding for DRR and CCA to construct the background for this compendium and outlines its chapters.

    Abstract

    It is widely recognized that investment is crucial to mitigating disaster damage and adapting to the effects of climate change. This point was emphasized in the Sendai Framework for Disaster Risk Reduction and successive agreements on climate change. The preceding chapters of this book identified various issues that need to be resolved and proposed policies and approaches accordingly. This chapter synthesizes the major findings and proposes innovative approaches to attain sustainable progress toward a resilient future in the Asian region. There are research gaps in many areas of investment in disaster risk reduction. There is a need to develop the estimating methods and the database of investments. The activities that constitute disaster management phases need to be well-coordinated and further developed. The trend in the increasingly adverse allocation of investment between ex-ante before disaster occurrence and response and recovery following disasters needs to be reversed. Since policy- and decision-makers must justify the allocation of budget among various priority activities, the methods to analyze the benefits of disaster risk reduction and climate change adaptation need to be improved. To overcome the paucity of finance, further research should be aimed at developing innovative approaches, such as green infrastructure, partnerships with the private sector, and burden-sharing mechanisms.

    Despite significant investment in disaster-resilient infrastructure, public understanding of these systems remains underexplored. This study examines Japanese public knowledge of social infrastructure (community facilities fostering social cohesion) and green infrastructure (natural systems integrated into urban environments). Through a nationally representative survey (n = 650), we assessed knowledge levels using open-ended questions analyzed via OLS regression. Results reveal significant knowledge gaps: respondents better understood social infrastructure than green infrastructure. Education emerged as the strongest predictor for both types, while social capital and perceived effectiveness of disaster measures correlated only with social infrastructure knowledge. Surprisingly, disaster experience showed no significant correlation with knowledge, suggesting experiential learning alone is insufficient. Age negatively correlated with green infrastructure knowledge, and females demonstrated higher social infrastructure knowledge than males. These findings highlight the need for targeted educational interventions to bridge the gap between infrastructure availability and public understanding, ultimately enhancing Japan's disaster resilience through improved citizen engagement.

    Conventional, top-down approaches have dominated disaster risk reduction (DRR) initiatives for decades, with central governments coordinating disaster preparation and recovery efforts, fortifying coasts, and building large-scale gray infrastructure such as levees and seawalls to mitigate potential threats. Critics have questioned the usefulness and applicability of this strategy, especially given the mixed results from recent shocks, including Japan’s 3/11 triple disasters. To investigate the degree to which experts in the field embrace traditional or alternative DRR models, we conducted 15 in-depth interviews with DRR specialists from the U.S. and Japan and systematically coded their responses using the NVivo software. Three key themes emerged from our analysis: 1) Leveraging community-based DRR and addressing issues such as tokenism; 2) prioritizing support networks; and 3) harmonizing top-down and bottom-up structures where national planning and local efforts are synergized, and decision-making is conducted through multi-stakeholder participation. Our results suggest that top-down policies alone cannot control disaster response; rather, a more inclusive governance structure that makes use of both institutional capacity and local knowledge will enhance DRR moving forward.

    The catastrophic 2004 Indian Ocean Tsunami, claimed over 200,000 lives and caused widespread devastation across multiple nations. The extent of the damage could have been mitigated, if communities had knowledge of tsunamis, understood their risks, prepared for such natural hazards, and left for higher grounds before the tsunami arrived. The event underscored the critical importance of community-based disaster risk reduction strategies and encouraged efforts worldwide to strengthen community resilience against coastal disasters. This article evaluates progress in community-based disaster risk reduction following the Indian Ocean Tsunami by analyzing the efforts of community response to major coastal disasters in various countries. We focus on the integration of indigenous knowledge with disaster management efforts, the role of education and public awareness programs, the challenges of sustaining initiatives, and the importance of multi-stakeholder involvement. By synthesizing lessons learned from diverse coastal disasters, this study contributes to the development of more effective and sustainable community-based disaster risk reduction strategies. It identifies the remaining issues and proposes essential policies that prioritize community resilience.

    Effective disaster management strategies are essential for strengthening community resilience and reducing risks, particularly as climate change intensifies the frequency and severity of natural hazards. This study explores the factors that influence how nearly 1,000 respondents across the United States perceive the effectiveness of different disaster management strategies, taking into account demographic variables, regional differences, past disaster experiences, levels of social capital, and individual expertise. Using a new, nationally representative survey of U.S. residents, the study investigates the perceived effectiveness of state-led approaches (e.g., early warning systems, levees, managed retreat), market-based mechanisms (e.g., insurance), and community-focused efforts (e.g., social cohesion) for disaster risk reduction (DRR). Demographic factors—such as age, race, and gender—as well as social capital levels and experiences of disaster-induced displacement significantly influence preferences for particular DRR strategies. Most notably, women, older age groups, individuals with high social capital, and those who have been displaced by disaster tend to favor community-focused approaches. The findings highlight the need for tailored DRR policies that consider local cultural contexts, engage diverse populations, and leverage both community and expert insights. By offering concrete policy recommendations, this study underscores the importance of an inclusive, multi-layered approach to disaster preparedness and management—one that integrates public perception and expertise to enhance overall climate resilience in the United States and beyond.

    Investing in disaster risk reduction is crucial for minimizing the impacts of disasters. However, little is known about the factors that influence changes in investment levels over time. This study aims to identify the key socio-economic drivers behind increases and decreases in flood protection investment in People's Republic of China (PRC). Such information is crucial for policy makers to justify flood investments. By analyzing data on flood protection expenditures, economic losses from floods, and other relevant indicators from 1980 to 2020, the study evaluates the relationship between investment and disaster impacts through the lens of the flood investment cycle model. It was found that the country succeeded in reducing flood damage because of increasing investment in flood protection. The results indicate that changes in PRC's flood protection investment have been driven by three major factors: the occurrence of major disasters, the fiscal situation, and shifts in government policies. Investment tended to increase following large-scale events, such as the 1998 Yangtze River Basin flood and the 2008 Wenchuan earthquake, which prompted policy changes and renewed focus on DRR measures. Fiscal constraints limited investment in the 1990s, but reforms and stimulus measures improved the financial situation, enabling increased spending on flood protection. PRC's experience in steadily reducing flood damage through sustained investment and policy commitment offers valuable lessons for other developing countries facing similar challenges.

    Climate change poses an existential threat to small island developing states, particularly atoll nations like the Republic of the Marshall Islands (RMI). This study examines the economic and financial challenges of implementing climate change adaptation measures in these vulnerable countries. Through a comprehensive literature review and a case study of the RMI, the costs and feasibility of various adaptation strategies, including coastal protection, land raising, and migration, were analyzed. Findings reveal that the financial requirements for effective adaptation far exceed the economic capacities of the RMI. Even basic protective measures require investments multiple times the country’s gross domestic product. The benefit-cost ratios of adaptation projects fall below 1 when evaluated solely on disaster risk reduction, highlighting the need for a paradigm shift in assessing adaptation investments in highly vulnerable nations. This study underscores the critical importance of international climate finance and support. While the RMI has received significant climate development finance, the scale of required adaptation measures far surpasses this level of assistance. The key challenges included not only debt sustainability concerns but also traditional land tenure systems, ecological impacts, and the limitations of conventional cost-benefit analyses in the context of national survival. This study offers valuable insights for policymakers, international organizations, and researchers working on climate resilience in vulnerable coastal nations.

    Cost–benefit analysis is crucial for prioritizing and justifying disaster risk reduction projects. This study aimed to identify important issues in the application of various cost–benefit analysis methods. It reviewed the diverse evolving processes of these methods in Japan and examined their advantages and limitations. In Japan, cost–benefit analysis methods are commonly applied to investments in flood protection engineering projects to evaluate their benefits. Furthermore, the analysis also estimated the damage prevention benefits of river improvement and the river water level reduction benefits of dam construction. The assets in danger of being damaged included houses, factories, infrastructures, and short-term economic activities. However, estimating all the benefits generated by flood protection projects remains a challenge. For example, the benefits of saving human lives or mitigating long-term indirect costs have not been counted. Therefore, this study proposes some concrete directions in this regard for future studies.

    In this study, we reviewed the literature on disaster risk reduction investment published since 2015, when the Sendai Framework for Disaster Risk Reduction was adopted, and then followed up with text mining analysis. The literature extracted from the databases of the World Bank and the Asian Development Bank (ADB), which are multilateral development banks (MDBs), offer new concepts in disaster risk reduction investment, such as the triple dividend of resilience and women-focused investment in resilience. Additionally, we found that solutions such as the Blueprint for Action (World Bank) had been proposed to promote investment. Conversely, many of the literature extracted from the Web of Science, a database of academic papers, are based on empirical research using quantitative methods and can be regarded as providing a certain level of evidence for the concepts that have been discussed in MDBs. The results of the co-occurrence network show that words such as “agriculture” and “fund” are characteristic of the World Bank literature, while “woman” and “community” are characteristic of the ADB literature. Moreover, the correspondence analysis implies a difference between the tendency of words to appear in the Web of Science literature and that in other MDB databases. Thus, when contemplating the direction of future academic research, the characteristic words of literature extracted from the MDB database using text mining could be deemed useful as a source of reference information to a certain extent.

  • Regional Policies and Initiatives on Climate Change and Disaster Risks: How Can Peacebuilding Assistance and Climate Change Adaptation Be Integrated?

    Mikio Ishiwatari

    2021.1

     More details

    Climate-fragility risks are regarded as “threat multipliers” that undermine the security of humans and the state. This chapter considers various development assistance approaches in managing climate-fragility risks. While development assistance agencies are supporting developing countries to strengthen efforts in climate change adaptation and peacebuilding, existing approaches in these two areas are not connected enough. The chapter examines gaps in the assistance approaches of managing climate-fragility risks: risk assessment, program time scale, and integration of approaches. Climate risk information is currently not used for peacebuilding programs, while risk assessment with respect to water availability and disasters under a changing climate would be useful in preparing projects under unstable regional situations. Peacebuilding programs focus on immediate needs such as rehabilitating the infrastructure destroyed, improving the livelihoods of local communities, and creating government capacities. Climate change adaptation programs aim at resolving issues from a long-term perspective, such as flood risk management and capacity building. Incorporating a long-term perspective into peacebuilding programs is a challenge. The chapter proposes practical approaches to fill these gaps in order to merge assistance approaches of peacebuilding with climate change adaptation.

    The Sendai Framework for Disaster Risk Reduction ("the Sendai Framework"), a set of guidelines for international disaster risk reduction ("DRR") initiatives, calls for multi-hazard approaches to pandemics, infectious diseases and other biological disasters as well as to natural disasters, i.e., for systematic management of a wide range of disasters. This constitutes a useful approach for reinforcing measures to combat COVID-19 and other infectious diseases, as it enables responses to spillover, cascading, compound and complex damage, and application of a significant track record of natural disaster management to battling infectious diseases. Stepping up approaches to multiple hazards inclusive of pandemics will require international cooperation in analyzing measures, drawing out the lessons to be learned, and supporting capacity-building in other countries.

  • FRAGILITY RISKS (CFR) IN DEVELOPMENT SECTORS

    Mikio Ishiwatari

    2019

     More details

    Climate change impacts on natural and human systems are increasing. Often affecting fragile economic, social and political systems, climate change is considered to be a serious ‘threat multiplier’. In this document, the risks on these existing systems are understood as climate fragility risks (CFRs). Considering CFRs in the development sector is necessary in order to address an important layer of additional current and future risks, which are largely not well understood or taken into consideration in the present development programing. The CFRs approach proposed in this document is aimed at ensuring that no one is left behind, through addressing the disproportionality that climate change impacts bring. This document proposes six principles to manage CFRs in key development sectors, namely (1) implement interdisciplinary approach, (2) focus on vulnerable groups, (3) promote preventive and adaptive measures, (4) enhance inclusive and participatory governance, (5) allocate and manage finances for CFR effectively and efficiently, and (6) build resilient and green infrastructure

    The Latin America and the Caribbean (LAC) region is one of the most disaster-prone areas in the world. Disasters have increasingly devastated the development effectiveness of the LAC countries. Had infrastructure been constructed with additional measures to prevent collapses due to natural hazard impacts, the region would have saved in the long run a significant amount of the public, private and human capital allocated to repairs and reconstruction. A key question is: what are the factors involved in preventing infrastructure collapse due to natural hazard impacts and how might these measures be implemented? This paper discusses the LAC countries’ sustainable infrastructure that has been shown to be resilient, continuing to operate without collapse even during hazardous events. The study reviews (i) the good practices for reducing vulnerability in Japan, (ii) the overall progress of LAC countries on disaster risk management, and (iii) the recent infrastructure damages due to disasters in LAC region and identifies lessons. Finally, using a comparative analysis of a selected case studies in LAC and Japan, the study identifies four approaches for hazard resilient infrastructure in the LAC region.

    Language:English  

    Human security will be progressively threatened by climate change, consequently development cooperation agencies such as JICA need to adopt approaches to strengthen resilience to climate-fragility risks. Currently, JICA's approaches to climate change adaptation and peacebuilding are not connected enough. There is a need for integrating assessments of climate risk and peace-building impacts as well as science, engineering and socioeconomic approaches. Furthermore, to address climate-fragility risks more broadly, Japan can build on its long history and extensive experience, for example in the water sector and disaster risk reduction.

    Flooding has become a serious issue in rapidly urbanizing countries. It is widely recognized that flood damages in urban areas can be decreased by taking an integrated risk management approach. This approach, however, has not been realized easily in major cities in Asia. The purpose of this paper is to examine the crucial issues in adopting the integrated approach to developing countries. It reviews Japanese experience and lessons of managing urban flood risks, and compares these lessons with situations in developing countries. It was found that establishing coordination mechanisms among a wide range of sectors is a crucial challenge. Furthermore, the paper proposes practical methods of promoting the integrated approach for urban flood risk management in developing countries.

     More details

    Water security and water quality affect numerous economic sectors and areas: agriculture, energy, disaster management, and others. Countries need balanced and integrated approaches that are economically, environmentally, and socially sustainable. Threats related to climate change have added to the complexity, and to the importance, of water resource management. Korea’s integrated water resources management approach since the 1990s reflects the country’s “green” climate-resilient development path. The Korean Green Growth Trust Fund’s (KGGTF) 3rd “Knowledge Note”, Promoting Green Growth through Water Resources Management: the Case of Republic of Korea, outlines key responses to Korea’s water resource challenges. The report highlights the Korean Government’s “Four Major River Restoration Project (4MRRP)”, a multi-purpose, green-growth infrastructure initiative. Involving five ministries and 78 local authorities in a comprehensive and integrated approach, the Note showcases lessons from 4MRRP for other countries to learn from Korea’s experience overcoming institutional, legislative, governance, technical and financial hurdles.

     More details

    Mainstreaming disaster risk management (DRM) into development policies and projects is recognized as the key to mitigate disasters, which hamper socio-economic development. However, limited activates have been conducted to support developing countries to enhance capacity of mainstreaming DRM. This chapter aims to propose approaches of capacity building for mainstreaming DRM. The lessons learned from disasters are useful for developing countries to mainstream DRM in development as well as to strengthen governance and practical measures in DRM. Each country can improve DRM by learning lessons from mega-disasters inside and outside the country. Various lessons were learned from the Great East Japan Earthquake and Tsunami (GEJE) in 2011, such as importance of preventive investment, preparedness for unexpected disasters, and risk communication. The chapter reviews the practices of (i) a joint research project between Japan and the World Bank (WB) “Learning from Megadisaster”, which collected lessons from the GEJE, and shared them with the rest of the world, and (ii) capacity building programs in DRM of Japanese assistance. It was found that there are obvious contrasts between these programs of the WB and Japan International Cooperation Agency in approach, targeted audience, and duration. The WB programs were designed to assist the developing countries in mainstreaming DRM and targeted a wide range of audience including policy makers, decision makers, and politicians. The WB efficiently conducted training activities by blending various tools, in particular advanced information and communication technologies. Japan International Cooperation Agency invites practitioners of government organizations from developing countries to Japan on a large scale to transfer Japanese practical technology on the ground. Through comparing these programs conducted by two organizations the chapter further proposes practical methods of exchanging knowledge among practitioners and decision makers in the world to mainstream DRM in development.

     More details

    On March 11, 2011, an earthquake of magnitude 9.0 occurred in the Pacific Ocean off the coast of Japan's Tohoku region. The Great East Japan Earthquake was the first 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. This report consolidates the set of 36 Knowledge Notes, research results of the joint study undertaken by the Government of Japan and the World Bank. It summarizes the lessons learned from the Great East Japan Earthquake and Tsunami and provides guidance to other disaster-prone countries for mainstreaming disaster risk management in their development policies. It is clear that financial resources alone are not sufficient to deal with disasters and to spur development. Technical assistance and capacity building are equally important. In Japan's case, the project learned how communities can play a critical role in preparing for and coping with natural disasters. Communities can help prevent damage from spreading, maintain social order, and provide support to the vulnerable. Only through technical cooperation can such know-how be passed on to other countries and be adapted to their local circumstances. The chapters that make up the main body of this report are built around the disciplines employed in the traditional disaster risk management cycle. Grouped into seven thematic clusters that track that cycle, the chapters treat structural measures (part 1) and nonstructural measures (part 2) as preventive options. Also covered is the emergency responses put in place after March 11 (part 3) and described the planning behind the reconstruction process (part 4). The handling of risk assessment and communication before and after the disaster are the subject of part 5. Part 6 deals with risk financing, insurance, and fiscal and financial management; part 7 with the progress of recovery and relocation.

    Language:English  

    The developing countries, which have weak governance and institution, face various difficulties for quick recovery in the aftermath of megadisasters. They have weak disaster management agencies, limited skilled and experienced staff and weak finance resources. Local governments are greatly overstretched because of a wide range of response and recovery activities. It takes some time for international development agencies to respond to disasters. This study aims to propose the practical institutional and governance mechanisms of quick recovery for developing countries and development agencies by examining practices in the East Japan Earthquake and Tsunami in 2011. The study observes that institutional and legislative features contributed to prompt recovery. For example, the governments opened roads leading to cities on devastated coasts in less than a week. Quick recovery can be attributed to robust measures prepared at normal times, which Japan have improved by learning lessons from past disasters including the Great Hanshin-Awaji Earthquake in 1995. The national government established the advance financial arrangements of subsidizing rehabilitation of public infrastructures to the local governments. Government offices have arranged prior agreements with the private sector to immediately commence recovery works. The government agencies organized to mobilize expert teams through their national networks. Structural measures of reinforcing bridges and other structures decreased recovery workloads and financial burdens. Also, the study argues challenges faced. The financial mechanizes focus on public facilities, and unfairly covers facilities owned by the private sector, such as railway, school and electricity. Local construction companies, which play crucial roles in quick recovery, are weakening capacities to respond to disasters because of budget decrease of public works.

    Japan has supported developing countries in promoting river projects for over the last half-century. The assistance started with structural measures of construction works and technical transfer in planning, constructing and maintaining structures, such as dams and river banks. The assistance has substantially contributed to socio-economic development of the countries. From the mid-90s, Japan started a holistic approach including community-based activities. This paper reviews the evolution of Japan’s assistance in the river sector. It was found that Japan is emphasizing the community-based activities to resolve issues. These issues include limited contribution to poverty reduction of the main purpose of official development assistance, limited development of non-structural measures, and limited coordination with other sectors. Also, the paper argues current issues of climate change adaptation and utilization of lessons form the Great East Japan Earthquake, and proposes practical approaches to address them.

    Publishing type:Research paper (international conference proceedings)  

    The Intergovernmental Panel on Climate Change (IPCC) projects that greater precipitation intensity and variability will increase flooding risks in many areas because of climate change. New planning methods in flood risk management are required to be developed. Stationarity is dead, and should no longer serve as a central default assumption in flood risk assessment and planning. The conventional planning methods assume that natural systems fluctuate with in an unchanging envelope of variability. Quantitative data on future extreme events is required as basic information to plan adaptation measures on climate change in flood risk management. The datasets of general circulation models of predicting global climates that were sources for the fourth assessment report of IPCC can be utilized for prediction on precipitation. The datasets of the super-high-resolution (20-km mesh) atmospheric General Circulation Model, which the Japanese Meteorological Research Institute and Japan Meteorological Agency developed by utilizing the Earth Simulator, are also available. This paper proposes planning methods for climate change adaptation in flood risk management through utilizing the datasets produced by supercomputer systems. The paper reviews the case studies of Japan International Cooperation Agency (JICA) of climate change adaptation in flood risk management that are planned according to the proposed methods.

    From a human security perspective, it is crucial to ensure that people affected by disasters<br />
    can resume normal daily life. This study aims to propose the methodologies of collaboration<br />
    between communities, development agencies, and NGOs for rehabilitation projects focusing<br />
    on individuals. JICA conducted various community-based rehabilitation projects following<br />
    the Indian Ocean Tsunami in 2004. The study observes that the JICA’s “four principle”<br />
    approach of integrating self-aid, community-aid, government-aid, and foreign-aid is useful<br />
    for community-based rehabilitation. This concept evolved from an important lesson learned<br />
    from the Kobe earthquake in 1995. The study further examines implementation difficulties<br />
    of all community-based JICA projects among three collaborative methodologies with communities<br />
    and NGOs: (1) subsidies to NGOs in Indonesia, (2) subcontracts with NGOs in Sri<br />
    Lanka, and (3) direct implementation by JICA in Maldives. It was found that the involvement<br />
    of foreign experts in the implementation of the subcontract or direct implementation methodologies<br />
    is crucial to attaining project quality. The subsidymethodology was the least effective,<br />
    since project quality depends on NGOs’ capacities that are difficult to evaluate during the<br />
    confusion following enormous disasters.

    Greater precipitation intensity and variability will increase the flood risks in developing countries because of climate change. Under an uncertain and changing climate, the conventional systems of planning methods in flood management can not be directly applied. This paper aims at proposing a planning method of climate change adaptation in flood risk management. It examines how to predict climate change effects on precipitation causing floods while dealing with the uncertainty. This paper further discusses flexible measures at a river basin level, instead of conventional measures of constructing long liner banks between mouths of rivers and the mountains. These measures include land use regulation, community-based disaster management, retarding basins, and banks protecting only strategic areas. It was found that the proposed method is applicable in flood risk management in Tagologan River Basin in the Philippines.

    The Philippines is one of the most disaster-prone counties in Southeast Asia. This paper reviews Japanese development assistance to the Philippines in disaster risk management, which has continued around 40 years. Most financing projects have supported structure measures, protecting some eight million people in 4,000 km2. Under technical cooperation Japanese engineers have transferred their technology to over 600 Filipino engineers. The assistance, however, has not necessarily attained human security, which focuses on empowerment and protection of individuals, and a mission of Japan International Cooperation Agency. Crucial issues were found in the assistance projects: (1) delayed construction projects; (2) limited contribution to poverty reduction; (3) limited support to communities; (4) limited involvement of local governments and communities; and (5) limited coordination with other related sectors. The paper further proposes approaches in future projects.

    Investments in disaster risk reduction are essential for mitigating disaster damage, an aim stressed by the Sendai Framework for Disaster Reduction. While a cost-benefit analysis is usually conducted for flood protection projects to confirm the viability of any new project, long-term economic analysis at the river basin or the regional scale has rarely been conducted. Policymakers need evidence that investments in flood protection contribute to regional growth. This study proposes a methodology for economic analysis of flood protection investments at the river basin scale and applies it to the Natorigawa River basin as a case study. The study estimates benefits, both past and future, by reducing damage caused by observed and simulated floods. It finds that the methodology is applicable and investments over the last seven decades in the river basin have been efficient, with an estimated benefit-cost ratio of 6.1. The methodology needs to be further simplified for application to developing countries, given the limited data and capacity in these countries. Moreover, methods for estimating the effects of climate change and the cost of replacing facilities need to be developed.

    As the population is growing and urbanization is progressing, higher numbers of people are exposed to disaster risks, especially in the developing countries. Climate change is further worsening the impacts of existing risks and introducing new ones. It is imperative that countries need to invest more in disaster risk reduction (DRR) as well as climate change adaptation (CCA) not only to minimize their impacts but also to build resilience.

    To date, various international arenas have recommended increasing investment in DRR. The Sendai Framework for DRR, adopted by the UN member states in 2015 during the Third UN World Conference on DRR, emphasizes investment as a priority for decreasing disaster risks and losses. The Yangon Declaration set the goal of doubling investment to address water-related disasters. However, most countries are not able to proactively invest enough in DRR. Understanding the current scale and estimate of investment and its effects is crucial for promoting DRR investment, but such information and estimates are rarely available.

    This book examines the current investment trends and issues in DRR and CCA. Based on specific case studies, field data and evidence, the book identifies challenges in increasing investment and recommends various investment policies and innovative approaches to sustainable progress towards a resilient future.

    Investing in flood protection is crucial in mitigating flood damage. However, most recent
    studies have not included an examination of actual investment data nor studied the relationships between investment in flood protection measures and damage or benefits. This paper aims at assessing policies toward flood protection by empirically analyzing flood damage and investment in flood protection measures in Asian economies. The trends of investment and damage in terms of the share of gross domestic product (GDP) vary by country. The People’s Republic of China (PRC) and Japan in the Post-WWII era were able to steadily decrease economic damage, while the Philippines, Taiwan, Republic of Korea (ROK), India, and Pakistan fluctuated in their budget outlays and damage. In cases of either a rising or decreasing trend, it was demonstrated that the Bayesian structural time series model can simulate investment to some degrees. It was also found that investment in flood protection is cost-effective at the regional and national levels. The annual benefits for the past two decades are estimated at 159
    billion USD in PRC and 120 million USD in the Philippines. The net benefit (benefit minus cost) accumulation from 2016 in Asian developing economies is predicted to reach 263 billion USD against an investment of 157 billion USD by 2030.

    The application of methods, tools and evidence from science and technology is fundamental to successfully
    anticipating and managing risk. The Sendai Framework for Disaster Risk Reduction (SFDRR) (UNISDR, 2015)
    recognises the importance of science and technology in its priority actions of implementing risk management
    measures (Calkins, 2015; Aitsi-Selmi et al., 2016; Shaw et al., 2016; Trogrlić et al., 2017). The SFDRR, which
    the UN General Assembly endorsed, charted the global course over the next 15 years from 2015 until 2030.
    The European Commission (2016a) published Action Plan on the Sendai Framework for Disaster Risk Reduction
    2015–2030: A disaster risk-informed approach for all EU policies in 2016. This 5-year action plan aims to guide
    the implementation of the SFDRR and to provide for a more systematic disaster-risk-informed approach in EU
    policymaking. The research community, engaging with the policy community, is expected to enhance the science–
    policy interface in policymaking. This subchapter describes how the role of science has evolved and scientists
    can support the implementation of risk management measures. Risk management mechanisms are evolving
    from top-down to networking approaches in Europe. Scientific knowledge can produce implementable solutions
    through engagement with stakeholders in addition to providing evidence-based information for decision-makers
    and government organisations (Scolobig et al., 2015). .

    Investment in disaster risk reduction (DRR) is indispensable for enhancing resilience and for achieving sustainable development. Therefore, understanding the current scale and effects of DRR investment is crucial for promoting it. This paper analyzes the current scale and trends of investment in flood protection and investment efficiency in Asia. The findings show that major flood-prone economies in Asia recently invested USD57 billion per year in flood protection, accounting for 0.26% of the total GDP of these economies. The total investment of nine developing economies accounts for 4.2% of their infrastructure investment. Low-income economies are unable to invest significantly in flood protection due to financial constraints and the need to invest in other priority areas. However, once economies reach the low-middle income stage, they have more financial leeway and can start increasing investment in flood protection. Asian economies have been investing efficiently in flood protection, with the benefits of investment increasing more than economic development and investment.

    Inclusive recovery efforts following disasters should encompass the needs and vision of various groups, especially women, youth, the elderly and people with disabilities, in order to realize the priority areas for disaster risk reduction (DRR) as stipulated in the Sendai Framework for Disaster Risk Reduction (SFDRR). This framework stresses enhancing disaster properness in recovery, rehabilitation, and reconstruction as priories. Accordingly, the planning methods of recovery programs need to respond to diverse needs of disaster-affected communities and improve their local governance. While the existing researches offer little analysis on gender and diversity dimensions in disaster recovery efforts, finding out the means to strengthen the disaster coping capacity of women and other diverse groups, as well as involving them in decision-making processes to enhance their disaster governance are indispensable in the effective implementation of the SFDRR.

    The successes of Japan’s disaster risk management (DRM) system as well as the ways in which that system could be improved are reflected in the lessons drawn from the Great East Japan Earthquake (GEJE) and presented in the initial reports from the Learning from Megadisasters project. The GEJE was the first 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. Extreme disasters underscore the need for a holistic approach to DRM. Single-sector development planning cannot address the complexity of problems posed by natural hazards, let alone megadisasters, nor can such planning build resilience to threats. Faced with complex risks, Japan chose to build resilience by investing in preventative structural and nonstructural measures; nurturing a strong culture of knowledge and learning from past disasters; engaging in wise DRM regulation, legislation, and enforcement; and promoting cooperation among multiple stakeholders, between government agencies and ministries, between the private sector and the government, and among multiple levels of governance, from local to national to international. The book 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 financing; 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.

    Between October 6 until 13, 2019, an extremely strong and large tropical cyclone, Typhoon Hagibis (meaning“speed” in Tagalog; also known as Reiwa East Japan Typhoon or Japan Typhoon Number 19 of 2019), caused widespread destruction across its path.It was the strongest typhoon to strike mainland Japan in decades, and one of the largest typhoons everrecorded in terms of its diameter. It was also the costliest Pacific typhoon recorded in history, causing a total of 15 billion US dollars in financial damage Typhoon Hagibis came only a month after another strong typhoon, Faxai (Reiwa Bōsō PeninsulaTyphoon), took a similar path, also causing heavy damage in several prefectures around the capital region. The Japan Meteorological Agency (JMA)issued a rare, highest-level warning of extreme rain in
    7 prefectures, including Saitama and Shizuoka, urging residents to evacuate or move to higher floors in the“nearest sturdy building” in order to avoid imminent
    danger. Less than an hour after the typhoon made landfall, the agency added five more prefectures to the extreme-rain warning list. JMA had warned that Hagibis could rival typhoon Ida of 19583, which killedmore than 1,200 people in Shizuoka Prefecture and the Tokyo region.
    Japan’s multi-hazard preparedness is globally recognized. During typhoon Hagibis, Japan’s advanced technology made it possible to forecast the risks in detail, and the media efficiently circulated the latest updates in a timely fashion. Strong infrastructure, such
    as embankments and dams, protected many areas from devastating floods. However, there were also some areas that could have been handled better. As with previous disasters, Japan’s aging population continues to be a matter of concern, and calls for revision of many policies. The vastness of the affected area was too large for the number of spontaneous volunteers who
    came forward to help. And because of the scale of the disaster, the management facilities of the disaster waste were overwhelmed and had to shut down temporarily in many areas, which delayed the cleaning activity. This report examines some of these issues, and summarizes the lessons that can contribute to better preparedness for future disasters.

    While there is growing awareness and concern regarding climate change, with a lot of active discussions surrounding the issue, there is not much information on several other risks facing the world such as urbanization, an increase in natural hazards, an ageing society, food and water crises, prolonged conflicts, etc. Innovative solutions are required now more than ever to identify these issues and address them in an effort to build a resilient society.
    A publication entitled “30 Innovations for Disaster Risk Reduction” was released at the Global Platform for Disaster Risk Reduction held in Geneva in May 2019, which stated that only high-tech tools should not be considered innovative and useful; rather, an appropriate strategy is imperative to change the current global situation and tackle the complexities of modern society.
    This publication entitled “30 Innovations linking DRR with SDGs” is the second volume in the “30 Innovations” series, and includes an additional 30 innovations focusing on 10 sectors— Emergency response, Gender, Health, Agriculture, Water, Children, Education, Disabilities, Livelihood, and Early warning—to demonstrate the strong association between DRR and SDGs.
    These 10 sectors were selected following detailed discussions by a group of experts in DRR, taking into consideration the 17 SDGs. It is not possible to discuss and consider DRR without examining its association with other sectors. It demonstrates the nature of complexities surrounding the DRR issue, which should also focus on both natural and man-made hazards such as technological and
    chemical threats. Given that the discussion and consideration on DRR is becoming increasingly interdisciplinary and complex, a strong partnership and collaboration beyond sectors is urgently
    required.
    In order to highlight the association between DRR and the 17 SDGs, each innovation in this publication highlights the most relevant SDG. For instance, most DRR innovations in this publication will contribute toward reducing poverty (Goal 1). Accordingly, this publication also
    seeks to highlight the strong association between DRR and SDGs, so that even those who have not been interested in the DRR issue could realize the need for promoting DRR activities for the successful implementation of SDGs, and could be encouraged to play an active role in DRR.
    This year, the world is facing a potential risk of wildfire caused by climate change, human development, and other composite reasons. When we talk about the underlying causes and solutions, it should take into consideration various perspectives such as DRR, development, environment, forest reservations, agriculture, health, education, energy, sustainable economic growth, etc. It is obvious that tackling natural disasters is no longer an issue of disaster risk
    management.
    Similar to the first volume, another survey was conducted on the most effective DRR innovations, which received 200 responses from academia, governments, the private sector, NGOs, and international and regional organizations. The innovation that was selected as the most effective from the 30 listed items in this publication was “Ecosystem-based DRR” under the “Livelihood” section. Again, this is not a high-tech product, but rather an issue concerning the preservation of what we already have. In fact, of the top 10 innovations selected, only one high-tech product (Earthquake early warning system) was included. Most of them were approaches, systems/ mechanisms and knowledge that already exist. It implies that it is not just high-tech products that require our attention and investment; rather, we should look into knowledge, materials,
    and approaches that are already available. We should consider how to maintain or channel these existing ideas, instead of focusing on developing expensive new technologies that require complicated procedures to apply.

    治水への投資は、仙台防災枠組が優先行動として強調しているように、洪水被害を軽減するために不可欠である。政策立案者が防災への投資を検討するにあたり、どれほど資金需要のギャップがあるのかの推定を必要とするが、現在、そのような推定値はほとんど利用できない。

    このペーパーはアジア地域における治水インフラ投資の財政ギャップを推定し、そのギャップを埋める政策とアプローチを提案することを目的としている。 2015年にはアジア地域の9つの主要な洪水頻発国と地域において336億米ドル、GDPの0.21%、を治水に投資したことが明らかになった。重回帰分析により、発展途上国における2016年から2030年までの治水インフラの年間需要は945億米ドル、気候変動の影響を加味すると984億米ドル、と推計される。将来需要と現在の投資レベルとの資金ギャップは約610億米ドル、気候変動の影響を入れると650億米ドルとなる。これはアジアの発展途上国のGDPの約0.24%にあたる。こうした国々は水害を危機から治水投資を拡大させる機会に変える必要がある。

    中華人民共和国、フィリピン、および日本の過去の経験を検討することにより、国家開発計画に治水を組み込み、セクター別の長期計画を策定することが投資を確保するのに効果的であることが明らかになった。気候変動適応における資金は増加しており、また、民間部門の資金を動員することで、さらなる財源を確保できる。また、コストを削減し、持続可能性を達成するには、革新的なアプローチも求められている。

    Climate change impacts on natural and human systems are increasing. Often affecting fragile economic, social and political systems, climate change is considered to be a serious ‘threat multiplier’. In this document, the risks on these existing systems are understood as climate fragility risks (CFRs).
    Considering CFRs in the development sector is necessary in order to address an important layer of additional current and future risks, which are largely not well understood or taken into consideration in the present development programing. The CFRs approach proposed in this document is aimed at ensuring that no one is left behind, through addressing the disproportionality that climate change impacts bring.
    This document proposes six principles to manage CFRs in key development sectors, namely (1) implement interdisciplinary approach, (2) focus on vulnerable groups, (3) promote preventive and adaptive measures, (4) enhance inclusive and participatory governance, (5) allocate and manage finances for CFR effectively and efficiently, and (6) build resilient and green infrastructure.

    “Towards Mabi’s Recovery – Lessons One Year On” is an effort of a group of professionals and practitioners through direct field observations, interviews and document review after the 2018 West Japan flooding in Mabi, Kurashiki, in the Okayama prefecture of Japan. The report builds on findings from Church World Service Japan’s earlier "Six Months Since Western Japan Flood: Lessons From Mabi" report. It identifies some of the most critical lessons from Mabi’s flood response and recovery efforts, structured around the themes of People and Communities, the Natural Environment and Organization. The analysis of these themes leads to Ways Forward which are aligned with the four Priorities for Action of the Sendai Framework for Disaster Risk Reduction (SFDRR) 2015-2030. It is hoped that this learning contributes not only to Mabi's ongoing recovery, but is also used to inform other disaster and specifically flood responses globally.

    Water security and water quality affect numerous economic sectors and areas: agriculture, energy, disaster management, and others. Countries need balanced and integrated approaches that are economically, environmentally, and socially sustainable. Threats related to climate change have added to the complexity, and to the importance, of water resource management. Korea’s integrated water resources management approach since the 1990s reflects the country’s “green” climate-resilient development path. The Korean Green Growth Trust Fund’s (KGGTF) 3rd “Knowledge Note”, Promoting Green Growth through Water Resources Management: the Case of Republic of Korea, outlines key responses to Korea’s water resource challenges. The report highlights the Korean Government’s “Four Major River Restoration Project (4MRRP)”, a multi-purpose, green-growth infrastructure initiative. Involving five ministries and 78 local authorities in a comprehensive and integrated approach, the Note showcases lessons from 4MRRP for other countries to learn from Korea’s experience overcoming institutional, legislative, governance, technical and financial hurdles

    On Thursday, February 13, IIEP co-hosted the Principles for Managing Climate Fragility in Development: A View from Japan with Dr. Mikio Ishiwatari. The event took place in the Lindner Family Commons at the Elliott School of International Affairs. The discussion was organized by the Master of Arts in International Affairs Program (MAIA) at the George Washington University, the Institute for International Economic Policy (IIEP), and the Center for Climate and Security. Often affecting fragile economic, social and political systems, climate change is considered to be a serious ‘threat multiplier.’ In this discussion, the risks of these existing systems were understood as climate fragility risks (CFRs). Dr. Mikio Ishiwatari presented a new interdisciplinary approach that integrates the assessment of peace-building needs with climate change vulnerability analysis. Considering CFRs in the development sector is necessary in order to address an important layer of additional current and future risks, which are largely not well understood or taken into consideration in the present development programming. Dr. Ishiwatari stressed the need to focus on those most vulnerable to ensure that no one is left behind.

  • Integrating disaster risk reduction and climate change adaptation: filling the financial gap toward a resilient society Invited International conference

    Mikio Ishiwatari

    RCAPS Onigiri seminar  2020.1  Ritsumeikan Center for Asia Pacific Studies : RCAPS

     More details

    Language:English   Presentation type:Public lecture, seminar, tutorial, course, or other speech  

    Venue:Beppu   Country/Region:Japan  

    The Onigiri Seminar was divided in four sections, exploring different dimensions of the connection between disaster risk reduction (DRR) and climate change adaptation (CCA), particularly in relation to finance.

    Dr. Ishiwatari opened the seminar by describing the damages caused in Tokyo area and northern Japan by Typhoon Hagibis in 2019. The example of this typhoon played two important roles. First, it served as an example of the effects of climate change; particularly, changes in the sea temperature around Japan suggest there is a connection between climate change and the magnitude of the typhoon. Second, Hagibis experienced also exemplified the importance of prevention. While there were some impacts, a greater tragedy was prevented thanks to the efforts for flood prevention that Japan has been implanting in the country for over a century.

    Then, Dr. Ishiwatari moved to the issue of how to implement similar strategies in Asia. Measuring current investment in Asia was the first step. He remarked how there is a “narrow corridor” of disaster damage and loss, in which relatively poor countries usually suffer large number of fatalities with small economic losses, while rich countries experiment the contrary: big losses but few deaths. This narrow corridor was more or less present in Asia, reflecting related patterns of investment as countries become richer. In the region Japan and China invest more, although The Philippines has become recently the top investor as a share of its gross development product (GDP). Overall, $57 billion USD per year are invested, or 0.26% of the GDP, 4.2% of the total infrastructure investment. Investments have shown to be cost-effective, paying off in the long term.

    The second step was to estimate the demand of flood protection investments expected from the region. Dr. Ishiwatari used a simple regression model for estimating the needs of major countries based on their income, population and other factors. The result is an annual average of $94.5 billion USD between 2016 and 2030, which implies a large increase from the 2015 $33.6 billion for the countries included in the study.

    Finally, the third step was to describe the multiple sources available to cover this financial gap. These included domestic financing sources, development assistance, climate change financing and the private sector. Several examples of these sources and how they contribute were described in the presentation. Major challenges are the mobilization of private capital and the inclusion of vulnerable groups considerations when designing actions in this sector.

    The presentation was followed by some comments and questions from the discussant and the audience, mainly in relation to the applicability of the Japanese experience to other countries and the difficulties in promoting preventive measures. Overall, the seminar was a great opportunity for students to learn about how DRR functions at the regional level and to get a grasp of the size of the sector and the challenges behind its finance.

    Language:English   Presentation type:Oral presentation (keynote)  

    Climate change is increasing the risks ofwater-related disasters, such as floods, droughts, and hightides in the Asia region. Estimating financial gaps of disasterrisk reduction is needed to consider investment policies, plansand financial arrangements. However, the estimates of the demandfor disaster risk reduction are rarely available, and academicliterature in this area is limited. Additionally, themethodology for estimation has not been established.
    The study analyzes the trends of budgets of flood protection inmajor flood-prone economies in Asia, and proposes methodologyfor estimating demand for flood protection infrastructure. Thedemand in the region until 2030 is estimated using regressionanalysis to apply panel data of possible socio-economic factors,and financial gap is estimated. The study also aims at proposingthe policies of filling the financial gap by examining policiesand approaches in the region.

    Language:English   Presentation type:Poster presentation  

    The integrated approach of involving a wide range of stakeholders is effective in reducing flood damage, which has become serious in rapidly urbanizing
    countries. This study aims at examining issues in adopting the integrated approach to mega-cities in developing countries. It reviews Japanese experience of
    flood risk management at a river basin in the Tokyo Metropolitan Area as a case study. It was found that the field office of the national government played
    important roles to establish a collaborative mechanism among stakeholders on the ground. The field office is at a good position to create relationships with
    local communities and government offices and to respond local needs. Personal rotation system between field offices and the Headquarter of the ministry
    contributed to strengthening knowledge management.

  • How can disaster risk management be strengthened by learning from disasters? International conference

    Mikio Ishiwatari

    2015.12 

     More details

    Language:English   Presentation type:Oral presentation (general)  

    Each country has strengthened disaster risk management (DRM) by learning from past natural disasters. The study aims to examine how organizations concerned can build upon the past disaster experiences and what are barriers to learning. It compares lessons from two mega-disasters in Japan: the Great Hanshin-Awaji (Kobe) Earthquake in 1995 and Great East Japan Earthquake (GEJE) in 2011, and examines which areas Japanese organizations and people could improve through drawing lessons from the Kobe Earthquake and respond to GEJE more properly than before. It was found that some Japanese organizations could mainstream DRM into their operations. Transport structures were not seriously damaged by earthquake shaking on March 11, 2011 and promptly reopened within a week following the earthquake. This is because infrastructure agencies had retrofitted all bridges of national highways and railways based on a lesson from the Kobe Earthquake. A wide range of emergency expert teams consisting of engineers, medical specialists, search and rescue experts and others had been established following the Kobe earthquake; and played crucial roles in responding to GEJE. It was also found that similar missteps were repeated when the mega-disasters stroke. Involving local governments and the private sector in DRM is a challenge. While various reports recommended improving management of emergency centers following the Kobe Earthquake, the same issue was pointed out again following GEJE. Private companies still need to improve business continuity plans, while many companies could not continue their business and suffered economic damages from the Kobe earthquake. While some three-fourths of the dead people at the Kobe earthquake died under collapsed old houses, retrofitting private housing is lagging behind the schedule. The study provides policy recommendations how to prepare for future disasters by learning lessons, and how to avoid similar failures.
