Breeding and housing wild animals in captive environments can pose challenges for their welfare. In South Africa, thousands of lions (Panthera leo) are bred and raised at commercial captive breeding facilities, so called ‘lion farms’, for use in tourism, trophy hunting and traditional medicine. To gain a better understanding of the potential welfare challenges faced by lions on farms we reviewed 91 peer-reviewed articles relating to lion welfare, identified via a systematic review of the scientific literature. Across these studies, we identified 170 different terms relating to negative behaviours and physical health afflictions. The majority of these terms were associated with disease and injury (124; 73%), followed by negative behaviours (19; 11%), negative mental experiences (15; 9%), nutritional concerns (7; 4%), and environmental challenges or discomfort arising from the animal’s surroundings (5; 3%). Of the 91 articles, 32 (35%) focused on data concerning captive lions. Only two studies focused specifically on data obtained from lion farms in South Africa, whilst the remainder reported on data collected from zoos, wildlife parks, sanctuaries, game reserves and private ownership. Our preliminary review of the scientific literature draws attention to some of the challenges associated with caring for lions in captivity, and outlines the potential significance of these welfare challenges for commercial lion farms. Our data highlight the apparent lack of scientific research involving captive lion welfare generally, particularly data collected at commercial breeding facilities in South Africa and the consequences this could have for the welfare of thousands of lions within the industry.

African lions (Panthera leo) are bred in captivity on commercial farms across South Africa and often have close contact with farm staff, tourists, and other industry workers. As transmission of zoonotic diseases occurs through close proximity between wildlife and humans, these commercial captive breeding operations pose a potential risk to thousands of captive lions and to public health. An understanding of pathogens known to affect lions is needed to effectively assess the risk of disease emergence and transmission within the industry. Here, we conduct a systematic search of the academic literature, identifying 148 peer-reviewed studies, to summarize the range of pathogens and parasites known to affect African lions. A total of 63 pathogenic organisms were recorded, belonging to 35 genera across 30 taxonomic families. Over half were parasites (35, 56%), followed by viruses (17, 27%) and bacteria (11, 17%). A number of novel pathogens representing unidentified and undescribed species were also reported. Among the pathogenic inventory are species that can be transmitted from lions to other species, including humans. In addition, 83 clinical symptoms and diseases associated with these pathogens were identified. Given the risks posed by infectious diseases, this research highlights the potential public health risks associated with the captive breeding industry. We recommend that relevant authorities take imminent action to help prevent and manage the risks posed by zoonotic pathogens on lion farms.

The use of animals and plants as traditional remedies for medical and magico-religious purposes has a long history of socio-cultural and economic importance in South Africa. Herein, we aim to characterize the social and economic value of wild animal species used in traditional, belief-based medicine within South Africa from traditional healers’ perspective and to explore healers’ knowledge of plant-based alternatives to wildlife-based derivatives for this type of trade. Through structured surveys with five traditional healers, we sought to gain insight into the range of wild animal species used, as well as the purpose, the perceived commercial value and the perceived availability of commonly used species. Particular focus was placed on exploring the socio-economic value of lions due to their prominence within the traditional medicine market, both in South Africa and internationally. Three of the respondents interviewed had been generating an income from traditional healing for between 30 and 50 years, and the overall monetary gain across all respondents was between ZAR 30,000 (1,800 USD) and 120,000 (7,200 USD) per annum. Our study confirms that a wide range of wild animal species are used in traditional healing practices in South Africa, for both medicinal and magico-religious purposes. The traditional healers we interviewed cited 20 common wild animals from a range of vertebrate classes including birds, reptiles, mammals, and one invertebrate. These included a number of species listed as threatened on the IUCN Red List of Threatened Species. Traditional healers cited 32 different uses for wild animal parts, as well as 19 alternative plant-based preparations. For lions specifically, four out of five practitioners listed lions among their top three profitable derivatives and three practitioners reported that lion had become the most rare or unavailable species in the last 5 years. Although our study is based on a limited number of interview participants, we believe that our findings provide valuable initial insights into the socio-economic drivers of traditional healing practices in South Africa, and that further research quantifying medicinal and belief-based use of wild animal ingredients and their plant-based alternatives could help to inform approaches to managing related pressures exerted on wild populations in South Africa in the future.

African lions (Panthera leo) are commercially farmed across South Africa for sport hunting, tourism, and the international bone trade, primarily in Southeast Asia. Despite its legal status, South Africa’s growing lion farming industry is a contentious issue. In 2020 a high-level panel was initiated to review the policies, legislation, and management regarding the breeding, hunting, trade, and handling of four wildlife species, including lions. In May 2021, it was announced that the government intends to amend existing permit conditions to prohibit lion breeding and tourism interactions with captive lions, as well as to stop issuing permits to new entrants into the industry, effectively ending lion farming. In order to follow this line of action, a comprehensive, well-managed plan will be necessary to execute a responsible exit from the industry as it currently stands. Using a “gap analysis” management tool, we aim to: (1) outline some of the key considerations regarding the current state of the lion farming industry in South Africa; and (2) propose specific action steps that could be taken within five key areas (regulation, animal welfare, health and safety, equitability, and conservation) to help inform a responsible transition away from this type of wildlife farming in the biodiversity economy. For our gap analysis, we conducted a semi-systematic literature search to compile key background information about the current state of the industry. This information was then used to identify corresponding desired management states, and steps that could facilitate a successful phase out of lion farming in South Africa. We hope our approach helps identify key considerations for a responsible transition and can help aid decisions during the management of this process.

The scope and scale of commercial captive lion breeding (CLB) in South Africa have rapidly increased since the 1990s. We conducted a qualitative systematic review using the PRISMA protocol to determine whether CLB provides a sustainable supply side intervention to reduce pressure on wild lion populations. A search was performed using three academic databases for sources published between 2008 and 2023. We collated and reviewed the data using an evaluation framework to determine the potential benefits and threats of CLB in the context of conservation. Among the 126 peer-reviewed and 37 grey literature articles identified, we found evidence suggesting that the framework’s criteria were not fully met, raising concerns that CLB may facilitate the demand for lions, their parts, and derivatives. Our findings further indicate a reasonable cause to doubt that the CLB provides a sustainable supply side intervention to meet the commercial demand for lions, their parts, and derivatives. This could adversely impact conservation of wild lion populations. We conclude that further research is required to effectively evaluate the purported conservation benefits of CLB. These insights may also have implications for the policy and governance of commercial predator breeding operations in South Africa and globally.
