Understanding what motivates people to act on climate change provides an opportunity to design more effective interventions, in particular, climate services interventions, by aligning them with factors that strongly influence action. Climate change risk perceptions have been shown to underlie action on climate change. Therefore, this study performs exploratory research to understand how various determinants of risk perceptions contribute and interact to influence climate change risk perceptions and professional action on climate change in East Africa, in order to inform the context-specific design of climate services. Using data collected through a region-wide survey, a model to risk perceptions and professional action was constructed through structural equation modeling. The model elucidates the cascading effects of variables such as age, gender, education, and personal values on action. In particular, it highlights a split in motivating factors among individuals with higher levels of self-enhancing values versus those with higher levels of self-transcending values. The model also highlights the prominent role that experience of extreme weather events, psychological proximity of climate change, climate change risk perceptions, and social norms play in motivating action. The model, therefore, offers a framework for prioritizing the various factors that motivate people to take adaptation action, which, in turn, provides a basis for informing climate services development going forward.
理解是什么激励人们采取行动应对气候变化，提供了一个机会来设计更有效的干预措施，特别是气候服务干预措施，通过使它们与强烈影响行动的因素保持一致。气候变化风险认知被证明是采取气候变化行动的基础。因此，本研究进行了探索性研究，以了解各种风险认知决定因素如何共同作用和相互作用，以影响东非的气候变化风险认知和专业行动，以便为特定背景的气候服务设计提供信息。本研究使用通过全区域调查收集的数据，通过结构方程建模构建了一个风险认知和专业行动模型。该模型阐明了年龄、性别、教育和个人价值观等变量对行动的级联效应。特别是，它强调了具有自我增强价值观的人与具有自我超越价值观的人之间激励因素的分裂。该模型还突出了极端天气事件的经验、气候变化的心理接近度、气候变化风险认知以及社会规范在激励行动方面的突出作用。因此，该模型为确定激励人们采取适应行动的各种因素提供了一个框架，这反过来又为未来的气候服务发展提供了依据。
