通过腐殖质形成在农业土壤中隔离碳来缓解气候变化是可持续农业的重要组成部分。旨在激励农民建立更多腐殖质的腐殖质计划仍然是最近的创新,因此,目前关于农民参与动机的知识是有限的。本研究通过分析农民参与腐殖质计划的意愿和影响因素,研究了采用非政府腐殖质计划来促进碳固存的情况。我们使用计划行为理论专门调查了农民采用腐殖质计划的行为因素。为此,我们使用190名德国农民的在线调查收集数据,并应用偏最小二乘结构方程模型.结果表明,(I)感知经济效益,(ii)农民同胞的行为,(iii)农民对气候变化的责任感对农民参与腐殖质计划的意愿有统计学上的显着影响。相比之下,感知的生态效益,政治压力,建立腐殖质培养措施的可能性,和腐殖质程序的先验知识没有统计学上的显著影响。我们的研究结果表明,农民参与腐殖质项目的决定受到经济利益的强烈影响,但是其他农民的行动和想法,以及他们自己对气候变化的道德主张,也起着至关重要的作用。我们发现农民缺乏关于腐殖质项目的注册和一般功能的知识,这可能是目前参与此类举措的最大障碍之一。
Mitigating climate change by sequestering carbon in agricultural soils through
humus formation is a crucial component of sustainable agriculture.
Humus programs that are designed to incentivize farmers to build more
humus are still recent innovations, so current knowledge about farmers\' motivation to participate is limited. This study examines the adoption of non-governmental
humus programs to promote carbon sequestration by analyzing farmers\' willingness to participate in
humus programs and influential factors. We specifically investigate behavioral factors underlying farmers\' adoption of humus programs using the Theory of Planned Behavior. To this end, we collected data using an online survey with 190 German farmers and applied partial least squares structural equation modeling. The results show that (i) perceived economic benefits, (ii) the actions of fellow farmers, and (iii) farmers\' sense of responsibility with regard to climate change have a statistically significant influence on farmers\' intention to participate in a humus program. In contrast, the perceived ecological benefits, political pressure, the possibility of establishing humus-building measures, and prior knowledge of
humus programs have no statistically significant influence. Our findings suggest that farmers\' decision to participate in humus programs is strongly influenced by the financial benefits, but the actions and thoughts of other farmers, as well as their own moral claims regarding climate change, also play a crucial role. We found that farmers lack knowledge about the registration and general functioning of humus programs, which can currently be one of the biggest barriers to participation in such initiatives.
