排干用于农业的泥炭地是土地利用部门温室气体（GHG）排放最集中的来源之一。关于根据《巴黎协定》目标减少温室气体排放的最有效战略的政策决定，以及能够阻止任何正在发生的土壤和生物多样性损失的战略，由于对拟议的缓解措施可能如何被农业部门接受缺乏了解而受到阻碍。研究已经确定了有效的温室气体减排措施，但这些措施在农场的成功采用取决于农民对实施这些措施的相对实用性的看法，以及采用这些措施将对农场业务产生的经济影响。在本研究中，采用离散选择调查方法Best-Worst Scaling，征求专家（气候变化、政策和生物多样性）和农民对可在农场层面减少温室气体排放的缓解措施的相对有效性、实用性和经济成本水平的意见。该方法能够根据有效性（专家意见）、实用性和经济成本（农民意见）对个别缓解措施进行排序。没有一项措施被评为既有效又实用，或者有效且成本低，但有一些措施被农民评为实用且实施成本低。这些措施包括：更有效的养分管理、减少耕作或不耕作、设置缓冲区、提高化石燃料效率和优化灌溉系统。一方面是“有效”措施，另一方面是“实用”和“经济”措施，两者之间的巨大差异凸显了减少农业有机土壤温室气体高排放所涉及的主要挑战。要解决这些挑战，需要采取多种措施，包括财政机制补偿农民成本上升和/或产量下降的损失，参与并提供建议，支持农民改变管理做法，以及农业创新和适应，以维持总体粮食生产和经济可行性。如果克服了这些挑战，对农业低地泥炭地进行更可持续的景观管理可以为实现国家和国际气候变化目标作出重大贡献。
Peatlands drained for agriculture are among the most intensive sources of greenhouse gas (GHG) emissions from the land-use sector. Policy decisions on the most effective strategies to reduce GHG emissions in line with Paris Agreement goals, alongside strategies that can halt any ongoing soil and biodiversity losses, are hindered by a lack of understanding on how proposed mitigation measures are likely to be received by the farming sector. Research has identified effective GHG reduction measures, but successful on-farm adoption of these measures is contingent upon farmer perceptions of the relative practicality of implementing the measures, and the economic impact that adoption will have on the farm business. In this study, Best–Worst Scaling, a discrete choice survey method, was utilised to elicit expert (climate change, policy and biodiversity) and farmer opinion on the relative effectiveness, practicality and level of economic cost of mitigation measures that can reduce GHG emissions at the farm level. The method enabled individual mitigation measures to be ranked by effectiveness (expert opinion), practicality and economic cost (farmer opinions). There were no measures ranked as both effective and practical, or effective with low cost, but there were measures ranked by farmers as practical and low cost to implement. These included: more effective nutrient management, reduced or no tillage, the installation of buffer zones, increased fossil fuel efficiency and the optimisation of irrigation systems. The strong divergence of ‘effective’ measures on the one hand, and ‘practical’ and ‘economic’ measures on the other, highlights the major challenges involved in reducing high GHG emissions from agricultural organic soils. Resolving these challenges will require a combination of financial mechanisms to compensate farmers for higher costs and/or reduced yields, engagement and advice to support farmers in adopting changes in management practice, and agricultural innovation and adaptation to maintain overall food production and economic viability. If these challenges are overcome, more sustainable landscape management on agricultural lowland peat could make significant contributions to achieve national and international climate change targets.
