Participatory extension programmes (PEPs) are a popular policy tool to stimulate the uptake of climate change mitigation practices on a farm level. Given the public investment in PEPs, reliable evaluation is important. However, few studies evaluate climate change PEPs. Moreover, the evaluations conducted so far do not correctly account for potential spatial effects, such as the influence of neighbouring farms on PEP participation. Therefore, this paper estimates the impact of PEP participation on the uptake of a climate change mitigation practice and soil management, and identifies the importance of spatial effects on PEP participation. A spatial propensity score matching method is applied to a dataset from Scotland, consisting of 134 PEP and 184 control farmers. The results show that PEP participation facilitates the uptake of soil management practices and that spatial dependence exists in farmers’ decision-making, indicating the need for the inclusion of spatial factors. This study contributes to the current literature by combining spatial econometric analysis and propensity score matching to conduct a quantitative evaluation of a climate change PEP. The evaluation methodology provides decision-makers with reliable insights into the potential contribution of PEPs towards climate change mitigation targets.

气候变化参与性推广计划对土壤管理实践影响的空间评估*

参与式推广计划 (PEP) 是一种流行的政策工具,可刺激农场层面采用减缓气候变化的做法。鉴于对 PEP 的公共投资,可靠的评估很重要。然而,很少有研究评估气候变化 PEP。此外,迄今为止进行的评估没有正确考虑潜在的空间影响,例如邻近农场对 PEP 参与的影响。因此,本文估计了 PEP 参与对气候变化减缓实践和土壤管理的影响,并确定了空间效应对 PEP 参与的重要性。将空间倾向得分匹配方法应用于来自苏格兰的数据集,该数据集由 134 名 PEP 和 184 名对照农民组成。结果表明,PEP 参与促进了土壤管理实践的采用,并且农民决策中存在空间依赖性,这表明需要纳入空间因素。本研究通过结合空间计量经济学分析和倾向得分匹配对气候变化 PEP 进行定量评估,为当前文献做出了贡献。评估方法为决策者提供了关于 PEP 对减缓气候变化目标的潜在贡献的可靠见解。本研究通过结合空间计量经济学分析和倾向得分匹配对气候变化 PEP 进行定量评估,为当前文献做出了贡献。评估方法为决策者提供了关于 PEP 对减缓气候变化目标的潜在贡献的可靠见解。本研究通过结合空间计量经济学分析和倾向得分匹配对气候变化 PEP 进行定量评估,为当前文献做出了贡献。评估方法为决策者提供了关于 PEP 对减缓气候变化目标的潜在贡献的可靠见解。
