Illegal wildlife trade (IWT) has increased in profile recent years as a global policy issue, largely because of its association with declines prominent internationally trafficked species. In this review, we explore the scale IWT, associated threats to biodiversity, and appropriate responses these threats. We discuss historical development IWT research highlight uncertainties that plague evidence base, emphasizing need for more systematic approaches addressing gaps way minimizes risk...
Many African protected areas (PAs) are not functioning effectively. We reviewed the performance of Zambia’s PA network and provide insights into how their effectiveness might be improved. PAs under-performing in ecological, economic social terms. Reasons include: a) rapidly expanding human populations, poverty open-access systems Game Management Areas (GMAs) resulting widespread bushmeat poaching habitat encroachment; b) underfunding Zambia Wildlife Authority (ZAWA) inadequate law...
Abstract Illegal wildlife trade is gaining prominence as a threat to biodiversity, but addressing it remains challenging. To help inform proactive policy responses in the face of uncertainty, 2018 we conducted horizon scan significant emerging issues. We built upon existing iterative scanning methods, using an open and global participatory approach evaluate rank issues from diverse range sources. Prioritized related three themes: developments biological, information, financial technologies;...
Abstract Overexploitation is a key driver of biodiversity loss but the relationship between use and trade species conservation outcomes not always straightforward. Accurately characterizing wildlife understanding impact it has on populations are therefore critical to evaluating potential threat poses informing local international policy responses. However, review recent research that uses trade‐related databases investigate these topics highlights three relatively widespread issues: (1)...
Abstract Legal hunting of threatened species—and especially the recreational practice “trophy hunting”—is controversial with ethical objections being increasingly voiced. Less public attention has been paid to how (even species) can be useful as a conservation tool, and likely outcomes if this was stopped. As case studies, we examine regulated legal two African rhino species in South Africa Namibia over last half‐century. Counter‐intuitively, removing small number specific males enhance...
Pangolins are threatened by overexploitation for local and international use. They subject to an commercial trade ban, also the focus of other interventions, including attempts at captive breeding. The impact that latter could have on conservation wild populations deserves consideration. We critically evaluate feasibility breeding (or farming) pangolins displace collection assess its potential pangolin using a recently published framework developed this purpose. Of 17 conditions posited need...
Commercial captive breeding and trade in body parts of threatened wild carnivores is an issue significant concern to conservation scientists policy-makers. Following a 2016 decision by Parties the Convention on International Trade Endangered Species Wild Fauna Flora, South Africa must establish annual export quota for lion skeletons from sources, such that threats lions are mitigated. As input quota-setting process, Africa's Scientific Authority initiated interdisciplinary collaborative...
Abstract That wildlife consumers prefer wild products to farmed alternatives is a widely reported finding in the conservation literature. These preferences for have been interpreted as evidence that farming and associated trade undermine efforts. conclusions then used influence policy recommendations design of interventions related use itself, well underpin consumer behaviour change campaigns. However, many species products, versus narrative based on assumptions over‐simplify can lead do not...
Consumer demand is an integral part of any market system, and the markets involving wildlife products are no exception ('t Sas-Rolfes et al., 2019). Tackling illegal trade (IWT) for benefit biodiversity conservation requires understanding influencing consumer (Veríssimo 2020). While reduction activities increasing & Wan, 2019), they remain poorly funded, with only 6% funds committed globally to reduce IWT focused on (World Bank Group, 2016). This lack investment also reflected in knowledge...
Understanding the effectiveness of Multilateral Environmental Agreements (MEAs) is critical to addressing international environmental issues. Here we articulate implied theory change (ToC) underpinning design and operation CITES (Convention on International Trade in Endangered Species Wild Fauna Flora), based an analysis Convention’s documented evolution. We use this as a framework critically evaluate Convention, with respect its stated aims, using range theoretical empirical insights....
Conservation and natural resource management are increasingly attending the ethical elements of public decisions. Ethical considerations challenging, in part, because they typically require accounting for moral consideration various human nonhuman forms life, whose interests sometimes conflict (or seem to conflict). A valuable tool such evaluations is formal analysis arguments. An argument a collection premises, logically interrelated, yield conclusion that can be expressed form, "We ought...
Persistent poaching fuelled by demand for elephant ivory and rhino horn continues to threaten these species. Despite international trade restrictions operating since the 1970s, limiting has remained a substantial challenge over last decade. The economy of such storable goods is driven combination persistent consumer market speculation, enabled weak governance, lack adequate resources species protection, alienation local people who pay costs living alongside We argue that restricting legal...
Conserving terrestrial megafauna presents distinct challenges to policymakers. Despite decades of evolving regulatory measures, wild rhinoceros populations remain threatened by illegal killing acquire rhino horn, a valuable commodity in East Asian markets. In Africa, conservation performance has varied with geography and over time. This research draws on institutional economic theories seek plausible explanations for such variable outcomes. Such suggest that variables as property rights...
Recent elephant poaching levels are a serious concern for conservationists. Opinions differ over how to deal with the upsurge and associated illegal ivory trade. Following CITES-imposed international trade ban voted in 1989, limited legal has been permitted two one-off sales. divided on what effect this had poaching. now also whether products should be outlawed worldwide, both between within countries. In midst of debate is question government agencies do existing stockpiles collected...
The number and area of wildlife ranches in Zambia increased from 30 1,420 km(2) 1997 to 177 ∼6,000 by 2012. Wild ungulate populations on 21,000 individuals ∼91,000 2012, while those state protected areas declined steeply. Wildlife ranching crocodile farming have a turnover ∼USD15.7 million per annum, compared USD16 the public game management which encompass an 29 times larger. industry employs 1,200 people (excluding jobs created support industries), with further ∼1,000 employed through...
Hunting regulation presents a significant challenge for contemporary global conservation governance. Motivated by various incentives, hunters may act legally or illegally, against the interests of conservation. Hunter incentives are shaped interactions between unevenly evolving formal and informal institutions, embedded in socio-ecological systems. To work effectively conservation, regulatory interventions must take these institutional into account. Drawing on analytical tools from...
Abstract Among factors that threaten wild populations of African megafauna, wildlife trade has gained prominence as a global policy issue, with concerted international campaigns aiming to influence the species such elephants, rhinos and lions. Trade is strongly contested, confounding attempts develop coherent approaches across jurisdictions through mechanisms Convention on International in Endangered Species Wild Fauna Flora (CITES). This undermines conservation efforts. Understanding...
Conservation practitioners routinely work within complex social-ecological systems to address threats facing biodiversity and promote positive human-wildlife interactions. Inadequate understanding of the direct indirect, short- long-term consequences decision making these dynamic can lead misdiagnosed problems interventions with perverse outcomes, exacerbating conflict. Participatory system dynamics (SD) modeling is a process that encourages stakeholder engagement, synthesizes research...
