(1) Background: Bees are the primary animal pollinators in most ecosystems, and honey bees ( L.) are important providers of pollination ecosystem services and products. Climate change is one of the major threats for honey bees. (2) Objectives and methods: Qualitative research using focus group discussions was carried out in northwestern Italy, to investigate the beekeepers' perceptions of climate change effects, the relevant management adaptations, and the main issues affecting the sector. (3) Results: Beekeepers reported several consequences related to severe weather events (weakening or loss of colonies; scarcity of nectar, pollen, and honeydew; decrease or lack of honey and other bee products; greater infestation by varroa; decline in pollination), making it necessary to provide supplemental sugar feeding, intensive transhumance, more effective and sustainable techniques for varroa control, and increased production of nuclei. A strengths, weaknesses, opportunities, and threats (SWOT) analysis was completed, displaying the factors able to strengthen or weaken the resilience of the beekeeping sector to climate change. (4) Conclusions: Thanks to their strong motivation and collaborative attitude, beekeepers succeed in adopting farm and bee hive adaptation strategies that are able to limit the climatic adverse effects. However, these findings highlight how the institutional and financial support for the beekeeping sector should be strengthened and better targeted.
(1) 背景:蜜蜂是大多数生态系统中的主要动物传粉者,而意大利蜜蜂(Apis mellifera L.)是授粉生态系统服务和产品的重要提供者。气候变化是意大利蜜蜂面临的主要威胁之一。(2) 目的和方法:在意大利西北部开展了焦点小组讨论形式的定性研究,以调查养蜂人对气候变化影响、相关管理适应措施以及影响该行业的主要问题的看法。(3) 结果:养蜂人报告了与恶劣天气事件相关的若干后果(蜂群衰弱或损失;花蜜、花粉和蜜露短缺;蜂蜜及其他蜂产品减少或缺乏;蜂螨侵害加剧;授粉量下降),这使得有必要提供补充糖喂养、密集转地放牧、更有效和可持续的蜂螨控制技术以及增加交尾群的生产。完成了优势、劣势、机会和威胁(SWOT)分析,展示了能够增强或削弱养蜂业应对气候变化恢复力的因素。(4) 结论:由于养蜂人积极性高且态度协作,他们成功采用了能够限制气候不利影响的农场和蜂箱适应策略。然而,这些研究结果凸显了应如何加强并更有针对性地为养蜂业提供机构和资金支持。
