With a renewed emphasis on evidence-based risk sensitive investment promoted under the Sendai Framework for Disaster Risk Reduction 2015-2030, technical demands for analytical tools such as probabilistic cost-benefit analysis (CBA) will likely increase in the foreseeable future. This begs a number of pragmatic questions such as whether or not sophisticated quantitative appraisal tools are effective in raising policy awareness and what alternatives are available.
This article briefly reviews current practices of analytical tools such as probabilistic cost-benefit analysis and identifies issues associated with its applications in small scale community based DRR interventions.
The article illustrate that while best scientific knowledge should inform policy and practice in principle, it should not create an unrealistic expectation that the state-of-the art methods must be used in all cases, especially for small scale DRR interventions in developing countries, where data and resource limitations and uncertainty are high, and complex interaction and feedback may exist between DRR investment, community response and longer-term development outcome.
Alternative and more participatory approaches for DRR appraisals are suggested which includes participatory serious games that are increasingly being used to raise awareness and identify pragmatic strategies for change that are needed to bring about successful uptake of DRR investment and implementation of DRR mainstreaming.
随着人们重新重视《2015-2030年仙台减少灾害风险框架》所倡导的基于证据的风险敏感型投资,在可预见的未来,对概率成本效益分析(CBA)等分析工具的技术需求可能会增加。这引发了一些实际问题,比如复杂的定量评估工具在提高政策意识方面是否有效,以及有哪些替代方法。
本文简要回顾了概率成本效益分析等分析工具的当前实践,并确定了其在小规模社区减灾干预措施应用中存在的问题。
本文表明,虽然原则上最佳科学知识应为政策和实践提供依据,但不应产生一种不切实际的期望,即必须在所有情况下都使用最先进的方法,特别是对于发展中国家的小规模减灾干预措施而言,那里数据和资源有限且不确定性很高,减灾投资、社区反应和长期发展成果之间可能存在复杂的相互作用和反馈。
文中提出了减灾评估的替代方法和更具参与性的方法,其中包括参与性严肃游戏,这种游戏越来越多地被用于提高认识,并确定实现减灾投资成功采用和减灾主流化实施所需的切实可行的变革策略。
