This paper describes a method for reducing the economic risks associated with predictable natural hazards by enhancing the resilience of national infrastructure systems. The three-step generalised framework is described along with examples. Step one establishes economic baseline growth without the disaster impact. Step two characterises economic growth constrained by a disaster. Step three assesses the economy's resilience to the disaster event when it is buffered by alternative resiliency investments. The successful outcome of step three is a disaster-resistant core of infrastructure systems and social capacity more able to maintain the national economy and development post disaster. In addition, the paper considers ways to achieve this goal in data-limited environments. The method provides a methodology to address this challenge via the integration of physical and social data of different spatial scales into macroeconomic models. This supports the disaster risk reduction objectives of governments, donor agencies, and the United Nations International Strategy for Disaster Reduction.
本文描述了一种通过增强国家基础设施系统的弹性来降低与可预测自然灾害相关的经济风险的方法。本文还描述了三步广义框架,并提供了示例。第一步建立没有灾害影响的经济基准增长。第二步描述了受灾害限制的经济增长特征。第三步评估了在灾害事件受到替代弹性投资缓冲时经济的弹性。第三步的成功结果是基础设施系统和社会能力的抗灾核心,更有能力在灾后维持国民经济和发展。此外,本文还考虑了在数据有限的环境下实现这一目标的方法。该方法通过将不同空间尺度的物理和社会数据整合到宏观经济模型中,为应对这一挑战提供了一种方法。这支持了政府、捐助机构和联合国国际减少灾害战略的减少灾害风险目标。
