Abstract

Adaptation to climatic change in smallholder agriculture is pivotal to ensuring food security in many developing countries. Research into adaptation to climate change in smallholder agriculture has often used capital-based indicator frameworks, with only limited consideration of the cognitive dimensions influencing adaptation motivation. In this study, we interviewed 327 farmers in far-western Nepal and the responses were used in structural equation modelling to quantify determinants of adaptation motivation. Results indicate that farmers with a higher level of adaptation appraisal are motivated to adapt, whereas the higher level of threat appraisal exhibited a weak influence. Social drivers such as incentives and subjective norms had a weak effect. Risk experience influenced adaptation motivation negatively. Adaptation cost was negatively related to the adaptation appraisal. Determinants of adaptation motivation varied across agroecosystems. These results suggest that effective adaptation policies must emphasise on the factors that positively contribute to adaptation motivation (e.g., adaptation efficacy) and target interventions that break down the barriers to adaptation (e.g., adaptation cost), while boosting trust and confidence in farmers to adaptation measures. Findings can inform adaptation policies in similar smallholder contexts of Asia/South Asia, while the research approach can be used to generate insights into farmers’ adaptation motivation globally.

是什么促使小农适应气候变化?来自尼泊尔西部偏远地区小农种植的见解
小农农业适应气候变化对于确保许多发展中国家的粮食安全至关重要。小农农业适应气候变化的研究通常采用以资本为基础的指标框架,对影响适应动机的认知维度考虑有限。在这项研究中,我们采访了尼泊尔西部偏远地区的327名农民,并将他们的回答用于结构方程模型,以量化适应动机的决定因素。结果表明,适应评价水平越高,农户的适应动机越强,威胁评价水平越高,农户的适应动机越弱。社会驱动因素(如激励和主观规范)的影响较弱。风险经历对适应动机有负向影响。适应成本与适应评价呈负相关。适应动机的决定因素因农业生态系统而异。这些结果表明,有效的适应政策必须强调对适应动机有积极贡献的因素(如适应效率)和打破适应障碍的目标干预措施(如适应成本),同时增强农民对适应措施的信任和信心。研究结果可以为亚洲/南亚类似小农环境下的适应政策提供信息,而研究方法可以用来深入了解全球农民的适应动机。

期刊介绍: Anthropocene is an interdisciplinary journal that publishes peer-reviewed works addressing the nature, scale, and extent of interactions that people have with Earth processes and systems. The scope of the journal includes the significance of human activities in altering Earth’s landscapes, oceans, the atmosphere, cryosphere, and ecosystems over a range of time and space scales - from global phenomena over geologic eras to single isolated events - including the linkages, couplings, and feedbacks among physical, chemical, and biological components of Earth systems. The journal also addresses how such alterations can have profound effects on, and implications for, human society. As the scale and pace of human interactions with Earth systems have intensified in recent decades, understanding human-induced alterations in the past and present is critical to our ability to anticipate, mitigate, and adapt to changes in the future. The journal aims to provide a venue to focus research findings, discussions, and debates toward advancing predictive understanding of human interactions with Earth systems - one of the grand challenges of our time.
