観賞用植物の貿易が、侵入性害虫や爬虫類、農業および環境への被害を引き起こしていることが報告されています。ヨーロッパのオリーブの木や切り花に紛れて、イタリアのトカゲや蛇などが北ヨーロッパに持ち込まれています。この輸入は気候変動による害虫の生存可能性の増加や、微小害虫・真菌の発見困難さによるリスクを伴います。また、水資源の枯渇や違法採取植物の流通、貿易の炭素排出量などの持続可能性の課題も浮き彫りにされています。研究者たちは規制強化と産業の持続可能性の向上を求めています。

Abstract

The multibillion dollar ornamental plant trade benefits economies worldwide, but shifting and rapidly expanding globalized supply chains have exacerbated complex environmental, sustainability, and biosecurity risks. We review the environmental and social risks of this international trade, complementing it with analyses of illegal trade seizures and plant contaminant interception data from the Netherlands and the United Kingdom. We show global increases in ornamental plant trade, with supply expansions in East Africa and South America, and highlight risks and impacts including biodiversity loss, aquifer depletion, pollution, undermined access and benefit sharing, and food security. Despite risk mitigation efforts, the interception data showed considerable volumes of contaminants in ornamental plant shipments, but taxonomic identification was not always possible, highlighting uncertainties in assessing biosecurity risks. With high-volume and fast-moving transit of ornamental plants around the world, it is essential that production standards are improved and that data on specific risks from trade are collected and shared to allow for mitigation.
