摘要

管理入侵物种对于减轻其对生态系统的负面影响至关重要,但如果无视其社会效益,则可能会引发冲突。自 15 世纪葡萄牙人发现圣多美岛以来,人类对该岛特有的丰富森林造成了巨大压力,许多物种被引入。其中包括 20 世纪中叶引入的入侵性西非巨型陆地蜗牛(Archachatina marginata),这种蜗牛现已在岛上广泛传播,对本地动植物构成了潜在威胁。我们通过家庭问卷调查、焦点小组讨论和半结构式访谈,评估了该物种的食用频率及其对全岛居民的社会经济重要性。我们探讨了蜗牛使用的普遍性和潜在驱动因素(如财富、家庭组成和职业多样性),并描述了商品链的特征,以确定与蜗牛贸易相关的人口群体。我们采访了 672 人(每户 1 人),进行了 6 次焦点小组讨论,并采访了属于 5 个子类别的 80 名主要参与者。蜗牛是消费量最大的丛林肉类,也是重要的收入来源,尤其是对妇女和失业青年而言。据报告,主要是在农村地区,生计无保障和匮乏是参与这一行业的驱动因素。在职业多样性较低的贫困家庭中,蜗牛收获更为频繁。销售往往发生在社区中根基稳固、儿童比例较高的家庭。这两种情况都是因为社区靠近原始森林。购买蜗牛在所有人口群体中都很常见,但与财富和职业多样性有关。为控制这种外来物种对岛上宝贵生态系统的影响而采取的干预措施应涉及社会的多个部门,以确保得到社会的支持。这需要充分考虑从该物种中受益的弱势人口群体的福利。

Trade and socioeconomic importance of an invasive giant snail in the endemic-rich island of São Tomé, Central Africa

Trade and socioeconomic importance of an invasive giant snail in the endemic-rich island of São Tomé, Central Africa

Managing invasive species is crucial to mitigate their negative impacts on ecosystems, yet conflicts may arise when their social benefits are disregarded. Human pressure on the endemic-rich forests of São Tomé has been high since the island was discovered by the Portuguese in the 15th century, and numerous species have been introduced. These include the invasive West African giant land snail (Archachatina marginata), which was introduced in the mid-20th century, is now widespread on the island, and is a potential threat to native flora and fauna. We assessed the frequency of consumption of this species and its socioeconomic importance to people across the island with household questionnaires, focus group discussions, and semistructured interviews. We explored the prevalence and potential drivers of use (e.g., wealth, household composition, and diversity of occupations) and characterized the commodity chain to identify demographic groups linked to the snail trade. We interviewed 672 people (1 person per household), conducted 6 focus groups, and interviewed 80 key actors belonging to 5 subcategories. The snail was the most widely consumed bushmeat and an important source of income, particularly for women and unemployed youth. Insecure and scarce livelihood alternatives, mostly in rural areas, were reported as drivers for trade involvement. Snail harvesting was more frequent in poorer households with low occupational diversity. Selling tended to occur in households that were well-established in the community and had a higher proportion of children. Both were stimulated by the proximity of communities to the native forest. Buying snails was common in all demographic groups, but it was linked to wealth and occupational diversity. Interventions to manage the impact of this introduced species on the valuable ecosystems of the island should involve multiple sectors of society to ensure societal support. This requires robust consideration of the welfare of vulnerable demographic groups that benefit from the species.

期刊介绍: Conservation Biology welcomes submissions that address the science and practice of conserving Earth's biological diversity. We encourage submissions that emphasize issues germane to any of Earth''s ecosystems or geographic regions and that apply diverse approaches to analyses and problem solving. Nevertheless, manuscripts with relevance to conservation that transcend the particular ecosystem, species, or situation described will be prioritized for publication.
