Bushmeat hunting, trade and consumption is a growing biodiversity and food security concern. Much of the collated research is currently limited to forested regions however, despite indications of the increasing threat in savannas. Savanna regions are biodiverse and often have high-value wildlife tourism industries, but also have rapidly-growing rural populations, often highly dependent on natural resources. In this systematic quantitative literature review we seek to understand the state of knowledge about bushmeat in savanna regions in Africa. We aim to identify gaps in the literature, both spatially and topically, understand what methodologies are used, what common recommendations are made and what interventions have been quantified. We identified 144 relevant studies from the literature. Although studies have increased over time and diversified thematically, there were strong biases. Most studies were conducted in Tanzania, with gaps in research in southern Africa and the Sahelian region. Additionally, only 25 of papers investigated interventions used to reduce bushmeat hunting, with traditional enforcement being the most common intervention studied (53 of intervention studies, 13 of papers). Other frequently recommended interventions such as alternative incomes received little attention (14 of intervention studies, 3.5 of papers). Further, although many studies cite common drivers of bushmeat hunting such as income or livestock, the evidence for these drivers was lacking and contradictory. We reveal that although bushmeat in savanna regions is gaining recognition, many gaps in knowledge remain. This is the first study to systematically quantify the research about bushmeat in African savannas and aims to inform future research. © 2018 Elsevier Ltd

非洲大草原丛林肉危机的证据：系统的定量文献综述

丛林肉狩猎、贸易和消费是一个日益严重的生物多样性和粮食安全问题。然而，尽管有迹象表明稀树草原的威胁越来越大，但大部分整理的研究目前仅限于森林地区。热带草原地区具有生物多样性，通常拥有高价值的野生动物旅游业，但也有快速增长的农村人口，通常高度依赖自然资源。在这篇系统的定量文献综述中，我们试图了解非洲稀树草原地区丛林肉的知识状况。我们的目标是找出文献中空间和主题的差距，了解使用了哪些方法，提出了哪些常见建议以及量化了哪些干预措施。我们从文献中确定了 144 项相关研究。尽管研究随着时间的推移而增加并且主题多样化，但存在强烈的偏见。大多数研究是在坦桑尼亚进行的，南部非洲和萨赫勒地区的研究存在差距。此外，只有 25 篇论文调查了用于减少丛林肉狩猎的干预措施，而传统执法是最常见的干预研究（干预研究中有 53 篇，论文中有 13 篇）。其他经常推荐的干预措施，如替代收入，很少受到关注（14 项干预研究，3.5 篇论文）。此外，尽管许多研究引用了收入或牲畜等丛林肉狩猎的常见驱动因素，但这些驱动因素的证据缺乏且相互矛盾。我们发现，尽管稀树草原地区的丛林肉正在获得认可，但仍存在许多知识空白。这是第一项系统量化非洲大草原丛林肉研究的研究，旨在为未来的研究提供信息。© 2018 爱思唯尔有限公司
