Abstract

Most research on hydrological risks focuses either on flood risk or drought risk, whilst floods and droughts are two extremes of the same hydrological cycle. To better design disaster risk reduction (DRR) measures and strategies, it is important to consider interactions between these closely linked phenomena. We show examples of: (a) how flood or drought DRR measures can have (unintended) positive or negative impacts on risk of the opposite hazard; and (b) how flood or drought DRR measures can be negatively impacted by the opposite hazard. We focus on dikes and levees, dams, stormwater control and upstream measures, subsurface storage, migration, agricultural practices, and vulnerability and preparedness. We identify key challenges for moving towards a more holistic risk management approach.

整合减少洪涝和干旱灾害风险战略的必要性

对水文风险的研究大多集中在洪水风险或干旱风险上，而洪水和干旱是同一水文循环的两个极端。为了更好地设计减少灾害风险(DRR)的措施和战略，重要的是要考虑这些密切相关现象之间的相互作用。我们展示了以下例子:(a)洪水或干旱DRR措施如何对相反危害的风险产生(意想不到的)积极或消极影响;(b)洪水或干旱抗灾措施如何受到相反灾害的负面影响。我们的重点是堤防、水坝、雨水控制和上游措施、地下储存、移民、农业实践以及脆弱性和准备。我们确定了迈向更全面的风险管理方法的关键挑战。

期刊介绍： Water Security aims to publish papers that contribute to a better understanding of the economic, social, biophysical, technological, and institutional influencers of current and future global water security. At the same time the journal intends to stimulate debate, backed by science, with strong interdisciplinary connections. The goal is to publish concise and timely reviews and synthesis articles about research covering the following elements of water security: -Shortage- Flooding- Governance- Health and Sanitation
