Abstract

The governance of flood resilience comprises an array of policy instruments that can be applied to reduce damages and risks to the communities. Policy instruments available at the local level tend to have the greatest impact on communities’ ability to absorb shock and resume normal operation. This study is the first attempt to analyze policy instruments and regulations guiding the progression of flood resilience measures in the Okanagan Valley, BC. It aims to offer recommendations specific to the local context and identify the best practices to improve flood resilience of the communities. Therefore, the study adopted a multistage methodology including literature review, stakeholder consultations with the organizations (consisting of municipalities, regional districts and First Nations) and quantitative analysis using present/absent criteria to measure prevalence of given indicators and five flood resilience classes. The results suggest that the flood resilience policies and strategies of 22 organizations in the Okanagan valley are predominantly focused on flood preparation and mitigation, whereas policies related to during and post-flood management are still in the infancy and do not offer satisfactory support. Notably, some organizations are proactive in recognizing looming flood risks, thus enacting essential policy measures to strengthen resilience. These results further highlight that these organizations have focused on a variety of measures to improve resilience, such as spatial planning, building construction setbacks, enhancing natural environment, protecting riparian areas, and stormwater management. As well, current flood resilient practices by the Prairies (Calgary) paved the way of how both regions can learn from each other. The study sheds lights on broader takeaways of what the findings of this study mean for other world regions. The study results are of great importance to the organizations across the Okanagan Valley as they lay the groundwork for resource mobilization to achieve flood resilience and sustainability.

不列颠哥伦比亚省奥卡纳根河谷的抗洪治理:当前实践和未来指示
抗洪能力治理包括一系列政策工具,可用于减少对社区的损害和风险。地方一级现有的政策工具往往对社区承受冲击和恢复正常运作的能力影响最大。本研究首次尝试分析指导不列颠哥伦比亚省奥肯那根河谷抗洪措施进展的政策工具和法规。它旨在针对当地情况提出具体建议,并确定提高社区抗洪能力的最佳做法。因此,本研究采用了一种多阶段的方法,包括文献综述、利益相关者与组织(包括市政、地区和原住民)的协商,以及使用存在/不存在标准来衡量给定指标的流行程度和五种抗洪能力等级的定量分析。结果表明,奥肯那根流域22个组织的抗洪政策和策略主要集中在洪水的准备和缓解上,而与洪水期间和洪水后管理相关的政策仍处于起步阶段,不能提供令人满意的支持。值得注意的是,一些组织积极主动地认识到迫在眉睫的洪水风险,从而制定了必要的政策措施来加强抵御能力。这些结果进一步表明,这些组织已将重点放在提高弹性的各种措施上,如空间规划、建筑施工挫折、改善自然环境、保护河岸地区和雨水管理。此外,大草原地区(卡尔加里)目前的抗洪措施为两个地区如何相互学习铺平了道路。这项研究揭示了这项研究结果对世界其他地区的更广泛意义。研究结果对整个奥肯那根河谷的组织非常重要,因为它们为资源动员奠定了基础,以实现洪水恢复力和可持续性。
