    ADRC ANNUAL REPORT Asian Disaster Reduction Center 2017 ANNUAL REPORT No.20 2017 Foreword The Asian Disaster Reduction Center (ADRC), which was established in Kobe in July 1998, will celebrate its 20th anniversary this year. Since its founding, ADRC has been focused on promoting multilateral disaster risk reduction cooperation at the community, national, and regional levels all across Asia and the Pacific. Our activities include exchanges of disaster management experts from government organizations, the collection and dissemination of relevant information, and surveys and research on multilateral disaster risk reduction cooperation. Thus far, as many as 105 officials from 26 member countries have participated in our exchange programs. These interpersonal networks are our most valuable assets when it comes to enabling ADRC to develop and implement future activities intended to improve the resilience of Asian countries. We have worked in cooperation with our member countries to implement a variety of programs for disaster education, including programs that apply space-based technologies to disaster risk reduction. ADRC has also developed the GLIDE system, which is a practical tool for integrating disaster data and databases archived by organizations around the world. Even as we continue these activities, this anniversary provides an opportune time for ADRC to discuss the strategies and initiatives we will adopt over the next 20 years. As ADRC chairman, I sincerely appreciate your cooperation in these efforts, and I invite you to join us in promoting DRR in Asia so that together we can build more resilient societies for all.

Tropical cyclones (cyclones) are natural meteorological events which cannot be prevented. However, the combination of their impacts and those of other stressors — such as poor water quality, crown-of-thorns starfish predation and warm ocean temperatures — can permanently damage reefs if recovery time is insufficient. In the short term, management response to a particular tropical cyclone may be warranted to promote recovery if critical resources are affected. Over the long term, using modelling and field surveys to assess the impacts of individual tropical cyclones as they occur will ensure that management of the Great Barrier Reef represents world best practice. This Tropical Cyclone Risk and Impact Assessment Plan was first developed by the Great Barrier Reef Marine Park Authority (GBRMPA) in April 2011 after tropical cyclone Yasi (one of the largest category 5 cyclones in Australia’s recorded history) crossed the Great Barrier Reef near Mission Beach in North Queensland.

    www.nature.com/scientificreports OPEN A robust operational model for predicting where tropical cyclone waves damage coral reefs Received: 09 February 2016 Marji Puotinen1, Jeffrey A. Maynard2,3, Roger Beeden4, Ben Radford1 & Gareth J. Williams5 Accepted: 22 April 2016 Tropical cyclone (TC) waves can severely damage coral reefs. Models that predict where to find such Published: 17 May 2016 damage (the ‘damage zone’) enable reef managers to: 1) target management responses after major TCs in near-real time to promote recovery at severely damaged sites; and 2) identify spatial patterns in historic TC exposure to explain habitat condition trajectories. For damage models to meet these needs, they must be valid for TCs of varying intensity, circulation size and duration. Here, we map damage zones for 46 TCs that crossed Australia’s Great Barrier Reef from 1985–2015 using three models – including one we develop which extends the capability of the others. We ground truth model performance with field data of wave damage from seven TCs of varying characteristics. The model we develop (4MW) out-performed the other models at capturing all incidences of known damage. The next best performing model (AHF) both under-predicted and over-predicted damage for TCs of various types. 4MW and AHF produce strikingly different spatial and temporal patterns of damage potential when used to reconstruct past TCs from 1985–2015. The 4MW model greatly enhances both of the main capabilities TC damage models provide to managers, and is useful wherever TCs and coral reefs co-occur. Tropical cyclones (hurricanes, typhoons; TCs) generate very rough seas that can severely damage vulnerable marine biota such as coral reefs.

  • Climate Change, Food Security, and Socioeconomic Livelihood in Pacific Islands
    Climate Change, Food Security, and Socioeconomic Livelihood in Pacific Islands This report assesses the impact of climate change on agriculture and fisheries in three Pacific Island countries, including the impacts on agricultural production, economic returns for major crops, and food security. Alternative adaption policies are examined in order to provide policy options that reduce the impact of climate change on food security. The overall intention is to provide a clear message for development practitioners and policymakers about how to cope with the threats, as well as understand the opportunities, surrounding ongoing climate change. Project countries include Fiji, Papua New Guinea and Solomon Islands. About the Asian Development Bank ADB’s vision is an Asia and Pacific region free of poverty. Its mission is to help its developing member countries reduce poverty and improve the quality of life of their people. Despite the region’s many successes, it remains home to the majority of the world’s poor. ADB is committed to reducing poverty through inclusive economic growth, environmentally sustainable growth, and regional integration. Based in Manila, ADB is owned by 67 members, including 48 from the region. Its main instruments for helping its developing member countries are policy dialogue, loans, equity investments, guarantees, grants, and technical assistance. About the International Food Policy Research Institute The International Food Policy Research Institute (IFPRI), established in 1975, provides research-based policy solutions to sustainably reduce poverty and end hunger and malnutrition. The Institute conducts research, communicates results, optimizes partnerships, and builds capacity to ensure sustainable food production, promote healthy food systems, improve markets and trade, transform agriculture, build resilience, and strengthen institutions and governance.

  • 5-3. Promoting Cooperation with Member Countries, International Organizations and Ngos
    5-3. Promoting Cooperation with Member Countries, International Organizations and NGOs ADRC places high priority on the development of institutional and human networks to share disaster information in Asia. Developing networks between professionals and their counterparts in member countries, adviser countries, and observer organizations is vital to promoting cooperation on disaster reduction efforts in Asia. Therefore, ADRC invites high level and management level officials, including deputy directors, directors, and managers, to its annual ADRC International meeting to encourage interpersonal exchanges. 5-3-1. The 2017 Global Platform for Disaster Risk Reduction The 2017 Global Platform for Disaster Risk Reduction was held in Cancun, Mexico, during 24th to 26th May 2017. The Global Platform, held bi-annually since 2007, was established as the main forum for those working for DRR from the national governments, the UN system, international organizations, regional organizations, academic institutes, civil society and the private sector to get together and to explore DRR challenges. The 5th meeting, co-hosted by the government of Mexico as well as UN-ISDR, took place outside Geneva for the first time. Diverse sessions were held throughout the three days. The 2017 GP was attended by largely 180 countries. From Japan, Mr. Habuka, Deputy Director General, Cabinet Office attended the meeting, and MOFA, Ministry of Land, Infrastructure, Transport and tourism, Japan Meteorological Agency sent delegates as well. In the special session on Build Back Better on 24th May, chaired by Mr.Habuka, Deputy Director General, Cabinet office, focused on the status and challenges of the policy efforts towards BBB by learning from the lessons in the past, and discussed how to build DRR strategies at national and subnational levels.
