Essential oils (EO) are considered as safe and sustainable alternatives of synthetically produced industrial raw materials. While EO are renewable resources their production is traced to land use, therefore employing nonrenewable resources. This fact is often neglected during market up-take, which is established on EO bioactivity efficacy.
Present study is aiming this knowledge gap through an innovative algorithm that employs spatial yield, bioactivity performance and fundamental experimentation details to calculate the land footprint. The proposed methodology is tested upon a concise pool of 54 EO, of which 9 originate from 8 culinary herbs, 27 from 3 juniper , and 18 from 6 crops. All 54 EO were subjected to repellent evaluation and 44 of them also to larvicidal, encompassing in the protocol both choice and no-choice bioassays.
Based on these bioprospecting data the proposed protocol effectively calculated the land footprint for all EO and bioassays. The repellent land footprint indicated as more sustainable the EO from savory, oregano, tarhan, thyme, Greek sage, and juniper berries for which each application corresponds to 3.97, 4.74, 7.33, 7.66, 8.01 and 8.32 m2 respectively. The larvicidal assessment suggested as more sustainable the EOs from savory, oregano, fennel, thyme, tarhan, and rue with land footprints of 1.56, 1.79, 2.16, 2.89, 3.70 and 4.30 m2 respectively.
The proposed protocol managed to calculate the land footprint for each EO and bioactivity and indicated the more sustainable EO per use based on widely available bioprospecting data.
精油（EO）被认为是合成工业原料的安全且可持续的替代品。虽然精油是可再生资源，但其生产与土地利用有关，因此会消耗不可再生资源。在基于精油生物活性功效的市场推广过程中，这一事实常常被忽视。
本研究旨在通过一种创新算法填补这一知识空白，该算法利用空间产量、生物活性表现和基础实验细节来计算土地足迹。所提出的方法在一组54种精油上进行了测试，其中9种来自8种烹饪香草，27种来自3种杜松，18种来自6种作物。所有54种精油都进行了驱避评估，其中44种还进行了杀幼虫评估，实验方案包括选择和非选择生物测定。
基于这些生物勘探数据，所提出的方案有效地计算了所有精油和生物测定的土地足迹。驱避土地足迹表明，来自夏香薄荷、牛至、迷迭香、百里香、希腊鼠尾草和杜松子的精油更具可持续性，每次使用分别对应3.97、4.74、7.33、7.66、8.01和8.32平方米。杀幼虫评估表明，来自夏香薄荷、牛至、茴香、百里香、迷迭香和芸香的精油更具可持续性，土地足迹分别为1.56、1.79、2.16、2.89、3.70和4.30平方米。
所提出的方案成功计算了每种精油和生物活性的土地足迹，并根据广泛可用的生物勘探数据指出了每次使用时更具可持续性的精油。
