Abstract

Extreme weather events have cost lives and financial losses across the United States. Moreover, they are expected to increase in frequency, and this will exacerbate their impact on vulnerable sectors such as agriculture. But how farmers could adapt to extreme weather events by adopting different conservation practices has received slight attention in the literature. This study examines how farmers' perceptions of drought and flooding influence their decisions to implement conservation practices in their conventional crop fields. Out of the 350 farmer responses we received, fewer than half indicated a likelihood to adopt no-tillage/reduced tillage (43%), cover crops (40%), crop diversification (37%), and integrated crop-livestock grazing (29%). Using this data and a multivariate probit modeling framework, we show that farmers’ decisions can be partly explained by their perception of drought but not by their perception of flooding. Specifically, the perceived number of drought years significantly increases the likelihood of adopting no-tillage/reduced tillage and diversified cropping in the future. However, the number of drought years is not significantly associated with the use of cover crops and integrated crop-livestock grazing. These results suggest that the effects of extreme weather events on adoption of conservation practices as adaptive measures vary across different practices. Therefore, adaptation policies that make use of conservation practices must be tailored to farmers’ needs and priorities to be effective.

了解农民对极端天气事件的感知和适应措施
极端天气事件在美国各地造成了生命和经济损失。此外,它们的频率预计还会增加,这将加剧它们对农业等弱势部门的影响。但是,农民如何通过采取不同的保护措施来适应极端天气事件,在文献中很少受到关注。这项研究考察了农民对干旱和洪水的看法如何影响他们在传统农田中实施保护措施的决定。在我们收到的350份农民回复中,只有不到一半的人表示有可能采用免耕/少耕(43%)、覆盖作物(40%)、作物多样化(37%)和作物-牲畜综合放牧(29%)。使用这些数据和多变量probit建模框架,我们表明,农民的决策可以部分通过他们对干旱的感知来解释,但不能通过他们对洪水的感知来理解。具体而言,干旱年数显著增加了未来采用免耕/少耕和多样化种植的可能性。然而,干旱年数与覆盖作物和作物-牲畜综合放牧的使用没有显著关联。这些结果表明,极端天气事件对采用保护措施作为适应性措施的影响因不同做法而异。因此,利用保护做法的适应政策必须适应农民的需求和优先事项,才能发挥效力。

期刊介绍: Climate Risk Management publishes original scientific contributions, state-of-the-art reviews and reports of practical experience on the use of knowledge and information regarding the consequences of climate variability and climate change in decision and policy making on climate change responses from the near- to long-term. The concept of climate risk management refers to activities and methods that are used by individuals, organizations, and institutions to facilitate climate-resilient decision-making. Its objective is to promote sustainable development by maximizing the beneficial impacts of climate change responses and minimizing negative impacts across the full spectrum of geographies and sectors that are potentially affected by the changing climate.
