Building REsilience to Multi-source Flooding in South/Southeast Asia through a Technology-informed Community-based approacH (REMATCH)

由于盛行的季风、丰富的河流系统和漫长的海岸线，由多种因素（通常包括强降雨、台风和热带风暴）造成的洪水每年反复影响许多东南亚/南亚国家的数百万人。迫切需要制定和实施有效的风险沟通和管理战略，使当地社区为未来的洪水做好准备，即提高认识，减少脆弱性，减轻影响，拯救生命，并最终发展复原力。基于社区的灾害风险管理通过让社区成员积极参与整个决策和执行过程，提供了一种成本效益高的自下而上的手段，以提高社区对风险的认识，为他们提供获得集体资源和知识的机会，并制定基于社区的备灾和适应/减灾方案。CBDRM已在东南亚/南亚国家实施，以减少洪水的影响并提高社区的抵御能力。然而，现有的CBDRM项目很少利用最新的遥感产品、用于洪水预测的高性能计算和公民科学/众包技术，这些技术在过去十年中取得了长足的进步。总的来说，这些提供了显著推进当前CBDRM实践的潜力。REMATCH的总体目标是利用最近科技进步带来的令人兴奋和及时的机会，制定创新和有效的基于社区的洪水风险管理战略，在建立社区抵御多种来源洪水的能力方面创造一个阶段性的变化。具体来说，在这个基础建设项目中，我们将1)组建一个跨学科的研究团队，建立广泛的研究人员与利益相关者的伙伴关系，以开发有效的方法，共同生产/分享知识，沟通和管理风险，增强社区对洪水的抵御能力；2)应用多灾种风险分析框架量化洪水风险，了解洪水灾害的主要驱动因素；3)调查和理解当代韧性建设的历史和文化含义以及对社会经济发展的影响；4)采用公民科学方法，建立基于众包和遥感数据流以及实时洪水建模技术的社区洪水预报和预警试点系统；5)确定发展社区抗洪能力的主要挑战，并制定衡量社区抗洪能力的初步方法。这些研究目标将通过精心设计的研究方案来实现，并在越南的一个案例研究地点实施和测试。在项目期间，我们还将评估在孟加拉国和其他东南亚/南亚国家实施GCRF完整提案的可行性。

Due to the prevailing monsoon, abundant river systems and long coastlines, floods, as a result of multiple drivers (commonly including heavy rainfall, typhoons and tropical storms) repeatedly affect millions of people in many Southeast/South Asian countries each year. There is an urgent need to develop and implement effective risk communication and management strategies to prepare the local communities for future floods, i.e. improve awareness, reduce vulnerability, mitigate impacts, and save life, and eventually develop resilience. Through actively involving community members throughout the decision-making and implementation processes, community-based disaster risk management (CBDRM) provides a cost-effective bottom-up means to improve the awareness of communities about risks, provide them with access to collective resources and knowledge, and develop community-based preparedness and adaption/mitigation programmes. CBDRM has been implemented in Southeast/South Asian countries to reduce the impacts of flooding and develop community resilience. However, existing CBDRM projects have rarely taken advantage of the latest remote sensing products, high-performance computing for flood prediction and citizen science/crowd sourcing technologies, which have experienced substantial advancement particularly in the last decade. Collectively, these provide the potential to significantly advance the current CBDRM practice.The overarching aim of REMATCH is to take on the exciting and timely opportunity from recent scientific and technological advances and develop an innovative and effective community-based flood risk management strategy to create a step change in building community resilience to flooding from multiple sources. Specifically in this foundation-building project we will 1) assemble an inter-disciplinary research team and establish an extensive researcher-stakeholder partnership to develop effective approaches to co-produce/share knowledge, communicate and manage risk, and enhance community resilience to flooding; 2) apply a multi-hazard risk analysis framework to quantify flood risk and understand the key drivers of flood hazards; 3) investigate and understand the historical and cultural implications for contemporary resilience building and impacts on socio-economic development; 4) adopt a citizen science approach to scope a pilot community-based flood forecasting and warning system based on crowd-sourced and remote-sensing data streams and real-time flood modelling technology; and 5) identify the major challenges in developing community resilience and develop a preliminary approach to measuring community flood resilience. These research objectives will be achieved through a carefully designed research programme, and implemented and tested in a case study site in Vietnam. During the project, we will also evaluate the feasibility for implementation in Bangladesh and other Southeast/South Asian countries for the full GCRF proposal.
