“…Given the inability of trade bans to solve the poaching crisis for several species (Conrad 2012), direct action against poachers and increased funding of law enforcement in exporting countries have been touted as the most efficient ways to curb excessive collection of wildlife to supply international markets (Holden and Lockyer 2021). Trade agreements can provide strong incentives to improve environmental commitments by both trading partners within their own territories, not only on borders and customs.…”

International wildlife trade is a major driver of species extinction and biological invasions. Anticipating environmental risks requires inferences about trade patterns, which are shaped by geopolitics. Although the future cannot be predicted, scenarios can help deal with the uncertainty of future geopolitical dynamics. We propose a framework for generating and analyzing scenarios based on four geopolitical storylines, distinguished by combinations of international trade barrier strength and domestic law enforcement degree across countries supplying and demanding wildlife. We then use historical data on bird trade to classify countries into geopolitical profiles and confirm that trade barriers and law enforcement allow predicting bird trade patterns, supporting our scenarios’ plausibility and enabling projections for future global bird trade. Our framework can be used to examine the consequences of geopolitical changes for wildlife trade and to advise policy and legislation. Reducing demand for wildlife and ameliorating global inequality are key for curbing trade related risks.

“…In demand-driven markets, suppliers' participation responds to price signals and so demand is filled at the available price (McNamara et al, 2016). Most classic models of illegal wildlife trade assume markets are demand-driven (Milner-Gulland & Leader-Williams 1992;Bowen-Jones & Pendry 1999;Milner-Gulland & Clayton 2002;Brashares et al 2004;Hall et al 2008;McNamara et al 2016;Holden & Lockyer 2021). However, if restrictions on the quantity that can be legally traded exist (e.g.…”

“…In demand‐driven markets, suppliers’ participation responds to price signals, so demand is filled at the available price (McNamara et al., 2016). Most classic models of illegal wildlife trade are based on the assumption that markets are demand driven (e.g., Bowen‐Jones & Pendry, 1999; Brashares et al., 2004; Hall et al., 2008; Holden & Lockyer, 2021; McNamara et al., 2016; Milner‐Gulland & Clayton, 2002; Milner‐Gulland & Leader‐Williams, 1992). However, if restrictions on the quantity that can be legally traded exist (e.g., as a result of a quota), decisions by the trader are made under a fixed supply (e.g., supply‐driven market).…”
