In recent years, the rainfall pattern in Taiwan has been affected by Climate Change and causing it to become extremely abnormal and unpredictable. The high-intensity and long-lasting rainfall makes the scale, scope and impact of flooding larger than before. Although various engineering measures have mitigating effects, it is difficult to predict the scale and location of the disaster, which highlights the indispensable importance of non-engineering measures for example early warning, notification and response. With the aim of integrating the abilities of the central and local governments, starting in 2012 the NCKU Disaster Prevention Research Center assisted the Tainan City Government in establishing and maintaining autonomous flood disaster prevention communities (based on villages). As of 2018, 35 autonomous disaster prevention communities have been established.
Prior to a disaster, the general public's awareness of disaster prevention and response is improved and disaster prevention through education and training, disaster prevention drills, research and development of community evacuation plans and disaster prevention maps, and provision of community disaster prevention and response equipment. Community weather warning information is provided during the disaster, and both the disaster and evacuation status is tracked, confirmed, and sent to the central and local governments. After the disaster, the situation will be monitored and investigated, and feedback will be rendered to revise and improve the community disaster prevention plan.
From the three phases of pre-disaster preparedness, disaster response and post-disaster recovery, the communities will be assisted by comprehensive counseling. An integrated platform will be developed for disaster prevention in communities and enables autonomous flood disaster prevention to become the core of the flood disaster response mechanism. The concept of self-help and mutual assistance will be established within and between communities, so that the resilience of the communities will be continuously enhanced to reduce the impact of flood disasters.
近年來臺灣地區降雨型態受氣候變遷影響，而有極端化的趨勢，高強度、長延時的降雨使得水患發生之規模、範圍及影響較以往為大，各項工程措施雖發揮一定效用，難以預測的災害規模及地點，也突顯預警、通報及應變等非工程措施不可或缺的重要性。成大防災中心協助臺南市政府以里為對象，結合中央及地方政府的能量，自民國101 年起建置及維運水患自主防災社區，截至民國107年已成立35 個自主防災社區。
