Promoting household-level adaptation measures is an important part of climate change adaptation policies to reduce vulnerability to droughts for (agro-)pastoral communities in sub-Saharan Africa. To develop effective supportive policies, it is important to get a better understanding of the needs in the communities. In this study, we, therefore, present the results of a discrete choice experiment in which we identify preferences for four different support types of drought adaptation in (agro-)pastoral communities in Kenya. We include four types of drought and adaptation support: water supply, emergency livestock fodder, adaptation subsidies, and adaptation training. A novelty of our study is that we link the results from our discrete choice experiment to behavioural factors of three established decision-making theories: expected utility theory, protection motivation theory and theory of planned behaviour. Including these theories in our analysis results in an improved understanding of the causal relationship between adaptation behaviour and preferences for adaptation support. We demonstrate that households in (agro-)pastoral communities are willing to pay for both adaptation support and emergency drought support. There is however clear heterogeneity in preferences for support related to behavioural factors. We discuss the implication of our results for drought risk adaptation policy.

肯尼亚对干旱风险适应支持的偏好：来自离散选择实验和三种决策理论的证据


促进家庭层面的适应措施是气候变化适应政策的重要组成部分，旨在降低撒哈拉以南非洲（农）牧社区对干旱的脆弱性。为了制定有效的支持政策，更好地了解社区的需求非常重要。因此，在这项研究中，我们提出了一个离散选择实验的结果，在该实验中，我们确定了肯尼亚（农业）牧区对四种不同干旱适应支持类型的偏好。我们包括四种类型的干旱和适应支持：供水、紧急牲畜饲料、适应补贴和适应培训。我们研究的一个新颖之处在于，我们将离散选择实验的结果与三种既定决策理论的行为因素联系起来：预期效用理论、保护动机理论和计划行为理论。将这些理论纳入我们的分析可以更好地理解适应行为和适应支持偏好之间的因果关系。我们证明，（农业）牧民社区的住户愿意为适应支持和紧急干旱支持付费。然而，与行为因素相关的支持偏好存在明显的异质性。我们讨论了我们的结果对干旱风险适应政策的影响。
