在北方部分地区,许多授粉物种正在减少,这可能对授粉和粮食生产的生态系统服务产生不利影响。因此,重要的是要了解如何以有效的方式管理主要面向粮食生产的生境,以提高传粉者的种群,以确保当前和未来的粮食安全。在欧洲,农业环境计划是促进农田自然保护的一种行之有效的方法。一些先前的研究表明,某些农业环境计划可能是有益的授粉种群,促进农业栖息地的植物多样性增加。然而,没有对这些干预措施的效率或成本效益进行分析。我们使用了一个在线调查,以评估在英格兰的种植者的看法保护级环境敏感的农业协议,关于不同的农业环境方案的有效性,以提高他们的农场授粉和实施成本。在农业环境计划中,被认为是最有效地提高传粉者的选择是那些有关改善植物多样性的领域岬和加强或恢复半天然草地。然而,这些办法由于费用高昂,一般来说并不是最有效的。绿篱管理措施被证明是最有效的,尽管被认为是相对无效的,由于这些选项的成本低。因此,我们发现,在提高传粉者的干预措施的有效性和效率之间往往存在不匹配。在作出实施干预措施的决定时,可能需要权衡取舍,在这一决策过程中应考虑到农场规模以及其他地方差异。
In parts of the northern hemisphere, many pollinator species are in decline, with potential adverse implications for pollination and the ecosystem service of food production. It is therefore important to understand how habitats primarily orientated towards food production can be managed in an efficient way to enhance pollinator populations for current and future food security. In Europe, agri-environment schemes are a well-established method for promoting nature conservation on farmland. Some previous studies indicate that certain agri-environment schemes may be beneficial to pollinator populations by promoting increased floristic diversity in agricultural habitats. However, there has been no analysis of the efficiency or cost-effectiveness of these interventions. We used an online survey to evaluate the perceptions of growers in England following the Conservation Grade environmentally-sensitive farming protocol, regarding the effectiveness of different agri-environment scheme options in enhancing pollinators on their farms and the costs of implementation. Options within the agri-environment schemes that were perceived as most effective in enhancing pollinators were those related to improving floristic diversity of field headlands and enhancing or restoring semi-natural grassland. However, these options were not generally the most efficient, due to their high cost. Hedgerow management interventions were shown to be the most efficient, despite being perceived as relatively ineffective, due to the low costs of these options. We have therefore found that there is often a mis-match between effectiveness and efficiency of interventions for enhancing pollinators. Trade-offs are likely to be necessary when making decisions on implementing interventions, and farm size as well other local differences should be taken into account in this decision-making process.
