A brief introduction to the Fifth Session of Global Platform for Disaster Risk Reduction, which was held in Cancun, Mexico, organized by United Nations International Strategy for Disaster Reduction (UN/ISDR) and hosted by the Government of Mexico from 22 May to 26 May 2017, was firstly provided. Combined with “Sendai Framework for Disaster Risk Reduction 2015-2030”, “Transforming our world: the 2030 Agenda for Sustainable Development”, and related work on natural disaster risk reduction at global, regional, country and local scales, some hot-topics and prospects of global platform for disaster risk reduction were put forward. Some findings were concluded, consisting of understanding disaster risk, disaster risk governance, building and enhancing resilience to disasters, coherence between the Sendai Framework, the 2030 Agenda for Sustainable Development and Climate Change Adaptation (CCA). Implementing the Disaster Risk Reduction (DRR) through cross-sectoral collaboration, removing barriers and promoting public-private cooperation in DRR and other types of partnership among multi-stakeholders will become the main force pattern of DRR in the near future. Large-scale disaster risk governance caused by multi-hazards (disaster cluster), disaster chain and disaster compound will be the main trend in scientific research of DRR. Building regional disaster risk reduction platform (e.g. the Silk Road Economic Belt and the 21st-Century Maritime Silk Road) and sharing the technologies and information of disaster risk reduction will be the main contents of DRR practices. Building and optimization of institutional mechanisms on DRR will be the trend of DRR idea. Improving and enhancing the support to communities, vulnerable groups and locals on DRR will be the main trend in DRR achievements’ application and demonstration in China.  相似文献

The construction of the Yangtze River Economic Belt is one of the major strategic initiatives to promote the sustained and steady growth of China's economy at current and the new normal stages. Comprehensive enhancing the governance levels of various natural disaster risks in the Yangtze River Economic Belt is the basic guarantee for promoting the implementation of the development strategy. Based on the multi-hazard integrated risk theory, the main disaster risks of the core cities (Shanghai, Wuhan, and Chongqing) of the Yangtze River Economic Belt and the major risk-earthquake disaster chain were systematically analyzed. The status and existing problems of multi-hazard integrated risk governance in the Yangtze River Economic Belt were expounded in this paper. The main problems include: Insufficient understanding of multi-hazard integrated risk formation mechanism; low level of safety fortification; Imperfect regional coordination and linkage mechanism; and insufficient role of insurance and reinsurance in risk transfer. Finally, the overall promotion strategies were proposed, including establishing multi-hazard integrated risk identification mechanism and governance capability evaluation system; comprehensive improving the fortification level of multi-hazard integrated risk prevention; establishing multi-hazard and multi-party linkage disaster monitoring and early warning systems; strengthening major disaster risk management and evacuation facilities construction; accelerating the construction of catastrophe insurance systems based on multi-hazard risks. This will provide a theoretical reference for major disaster risks studies in the Yangtze River Economic Belt.  相似文献

Climate change and land use/land cover change have resulted in water shortage, degraded ecosystem services, and increased disaster risks across the world. Developing strategies and measures for achieving regional and global sustainability in the face of these environmental problems is a key topic of current climate change research. This paper provides an overview of the 973 project, entitled “Integrative Modeling and Strategic Planning for Regional Sustainability under Climate Change”, including its background, relative progresses, key scientific questions, major research elements, methodology, and expected outcomes. The proposed research is based on sustainability science, guided by the idea of Orderly Human Activities (OHA), and implemented through an integrated methodology of combining field observations, simulation experiments, and scenario analysis. The main objectives of the project are: to quantify the relationship between human activities and climate change, to assess the impacts of human activities on ecosystem services and human well being in the face of climate change, and to develop an integrated model of climate change, OHA, and regional sustainable development. The ultimate goal is to provide a landscape/regional-scale strategy for sustainable development in the face of climate change. The project is expected to help advance the science and application of landscape sustainability science and land system design, particularly in terms of linking climate change, ecosystem services, and human well-being in the dry land region of China.  相似文献

Managing the risks of extreme events such as natural disasters to advance climate change adaptation (CCA) has been a global focus. However, a critical challenge in supporting CCA is to improve its linkage with disaster risk reduction (DRR). Based on discussions on similarities and differences between CCA and DRR concerning their spatial–temporal scales, main focuses, preferred research approaches and methodologies, etc., this paper tentatively put forward an analytical framework of “6W” for linking DRR with CCA. This framework presented preliminary answers to a series of fundamental questions, such as “What is adaptation with respect to disaster risk?” “Why adaptation is needed?” “Who adapt to what?” “How to adapt?” “What are the possible principles to assess the adaptation effect?” To bridge the research gaps between CCA and DRR, it is imperative to associate the adaptation actions with both near-term disaster risk and long-term climate change and formulate adaptation strategies at various spatial–temporal scales by embracing uncertainty in a changing climate.  相似文献
