Floods continue to hit many countries, both less developed and industrialized, bringing human suffering and immense economic damage (see floodobservatory.colorado.edu/). Hurricane Florence and Typhoon Mangkhut were just the most recent reminders of the disruption that flooding can bring. Hence, striving to improve the flood-risk governance system has broad relevance. Yet, the reduction of flood risk, understood globally as a combination of hazard, exposure, and vulnerability, is a rather distant goal (Fig. 1).

意见：减少洪灾风险：结构性措施和多样化策略[可持续性科学]

洪水继续袭击许多欠发达和工业化国家，给人类带来痛苦并造成巨大的经济损失（请参见Floodobservatory.colorado.edu/）。佛罗伦萨飓风和山竹台风只是最近洪水的提醒，洪水可能带来破坏。因此，努力改善洪水风险治理体系具有广泛的意义。然而，降低洪水风险是一个遥不可及的目标（图1），降低洪水风险在全球范围内被认为是灾害，暴露和脆弱性的综合。
