Due to climate change, the frequency and intensity of droughts are expected to increase. To improve resilience to droughts, proactive drought management is essential. Economic assessments are typically included to decide on the drought risk-reducing investments to make. The choice of both methods and scope of economic assessments influences the outcome, and thus the investment choice. This paper aims to identify how comprehensively economic assessments are applied in practice. Through a systematic literature review, 14 actual economic assessments are identified and their methods are evaluated based on seven criteria for economic assessments as derived from the United Nations Framework Convention on Climate Change (UNFCCC). The results show that in practice, economic assessments rarely address all criteria. Applying a limited number of criteria reduces the scope and narrows the approach, possibly leading to the underestimation of drought risk reduction approaches' related benefits. Applying the seven criteria in practice will improve the results of economic assessments of drought risk reduction measures, allowing for optimal investment selection. Based on the different criteria, a Framework for Economic Assessments of Drought Risk-Reducing Applications (FEADRRA) is proposed. Applying the criteria of the framework can support decision-makers in drought risk management and in carrying out the most fitting drought interventions.
由于气候变化，预计干旱的频率和强度将会增加。为了提高对干旱的适应能力，积极的干旱管理至关重要。通常会进行经济评估，以决定进行哪些减少干旱风险的投资。方法的选择和经济评估的范围都会影响结果，从而影响投资选择。本文旨在确定经济评估在实践中是如何全面应用的。通过系统的文献回顾，确定了 14 项实际的经济评估，并根据联合国气候变化框架公约（UNFCCC）得出的七个经济评估标准，对其方法进行了评估。结果表明，在实践中，经济评估很少能满足所有标准。应用有限数量的标准会缩小范围和方法，可能导致低估减少干旱风险方法的相关收益。在实践中应用这七个标准将提高减少干旱风险措施的经济评估结果，从而能够进行最佳的投资选择。基于不同的标准，提出了减少干旱风险应用的经济评估框架（FEADRRA）。应用该框架的标准可以支持决策者进行干旱风险管理和实施最合适的干旱干预措施。
