农业做法的微小变化具有减少温室气体排放的巨大潜力。然而，在地方一级实施这些做法往往受到一系列障碍的限制。了解这些障碍对于确定有效措施、这些措施的实际缓解潜力以及确保实施的政策需求至关重要。在这里，我们评估了在地方层面实施缓解措施的行为、文化和政策障碍，这些障碍对农民意味着微小的改变。与案例研究相关的潜在缓解措施的选择是基于对以往实证研究的文献综述。为确定这些潜在做法的优先次序，采取了两种有利益攸关方（专家和农民）参与的方法：（a）对专家小组的选择进行多标准分析;（B）根据对农民的调查分析执行障碍。MCA考虑了两种未来气候情景--当前气候和更干燥和更温暖的气候情景。结果表明，考虑到两种情景下的多个标准，所有潜在的选定做法都适合缓解。然而，如果所有的实施障碍具有相同的影响，案例研究中首选的缓解措施将是改变施肥管理和使用覆盖作物。在对农民进行的调查进行计量经济学分析的基础上，确定了实施这些做法的障碍。结果表明，农民对环境的关注、财政激励措施和获得技术咨询的机会是确定其执行障碍的主要因素。这些结果可能有助于制定有效的缓解政策，并将其纳入2020年欧盟共同农业政策审查。
Small changes in agricultural practices have a large potential for reducing greenhouse gas emissions. However, the implementation of such practices at the local level is often limited by a range of barriers. Understanding the barriers is essential for defining effective measures, the actual mitigation potential of the measures, and the policy needs to ensure implementation. Here we evaluate behavioural, cultural, and policy barriers for implementation of mitigation practices at the local level that imply small changes to farmers. The choice of potential mitigation practices relevant to the case study is based on a literature review of previous empirical studies. Two methods that include the stakeholders' involvement (experts and farmers) are undertaken for the prioritization of these potential practices: (a) Multi-criteria analysis (MCA) of the choices of an expert panel and (b) Analysis of barriers to implementation based on a survey of farmers. The MCA considers two future climate scenarios - current climate and a drier and warmer climate scenario. Results suggest that all potential selected practices are suitable for mitigation considering multiple criteria in both scenarios. Nevertheless, if all the barriers for implementation had the same influence, the preferred mitigation practices in the case study would be changes in fertilization management and use of cover crops. The identification of barriers for the implementation of the practices is based on the econometric analysis of surveys given to farmers. Results show that farmers' environmental concerns, financial incentives and access to technical advice are the main factors that define their barriers to implementation. These results may contribute to develop effective mitigation policy to be included in the 2020 review of the European Union Common Agricultural Policy.
