Abstract

In the eastern Corn Belt of the United States, climate change is projected to bring warmer and wetter conditions, with more variability in the seasonal timing of rainfall, creating a multitude of challenges for agricultural production. While there are multiple adaptations to reduce the vulnerability of production to a changing climate, these adaptations have varying implications for other ecosystem services such as soil health, carbon sequestration and water quality. We explore how beliefs about and experiences with climate change might influence adaptations that vary in their provisioning of a variety of ecosystem services, and how these adaptations may vary by characteristics of the farm and farmer. Survey data were collected from 908 respondents in August through October 2019. We find only one proposed adaptation, additional tile drainage, is associated with self-reported prior negative experiences with climate change and concern about future impacts. The other proposed adaptations (i.e., cover crops, filter strips, additional fertilizer) are associated with farmer identity. The type of farmer who is likely to adapt is generally reminiscent of the type who engage in conservation practices: younger, more educated, with off-farm income and larger farms. Our results indicate that many proposed adaptations are not perceived as effective ways to mitigate specific climate driven impacts. However, increasing tile drainage is perceived as such, and there may be a need to offset the potential negative impacts to water quality of this likely adaptation through the promotion of edge-of-field filtration practices.
气候恶化的影响可能导致农业行动不适应
在美国东部玉米带,预计气候变化将带来更温暖、更潮湿的条件,降雨的季节性变化更大,给农业生产带来诸多挑战。虽然有多种适应措施来降低生产对气候变化的脆弱性,但这些适应措施对土壤健康、碳固存和水质等其他生态系统服务具有不同的影响。我们探讨了对气候变化的信念和经历如何影响在提供各种生态系统服务时不同的适应,以及这些适应如何因农场和农民的特点而不同。调查数据收集自2019年8月至10月的908名受访者。我们发现,只有一种拟议的适应措施,即额外的瓷砖排水,与自我报告的先前对气候变化的负面经历和对未来影响的担忧有关。其他拟议的适应措施(即覆盖作物、过滤带、额外肥料)与农民身份有关。可能适应的农民类型通常让人想起从事保护实践的农民类型:更年轻、受教育程度更高、有非农收入和更大的农场。我们的研究结果表明,许多拟议的适应措施并没有被视为减轻特定气候影响的有效方法。然而,增加瓷砖排水被认为是这样的,可能需要通过推广现场边缘过滤实践来抵消这种可能的适应对水质的潜在负面影响。

期刊介绍: Weather, Climate, and Society (WCAS) publishes research that encompasses economics, policy analysis, political science, history, and institutional, social, and behavioral scholarship relating to weather and climate, including climate change. Contributions must include original social science research, evidence-based analysis, and relevance to the interactions of weather and climate with society.
