There is a relative dearth of literature on both the effects of cross-border interdictions and the impact of different types of interventions on international drug trafficking. This study identifies the main trafficking routes for cocaine and heroin, along with comparing the disruptive effects induced by targeted and non-coordinated interventions. It adopts a social network approach to identify the routes along which cocaine and heroin are trafficked, and then simulates the impact of different interdiction strategies on these two trafficking networks. The findings indicate that targeting countries based on their respective positions in the networks, as opposed to on the basis of the quantity of drugs exchanged, is more likely to disrupt drug flows. More specifically, concentrating law enforcement resources on countries with several incoming or outgoing trafficking connections, or those countries that mediate between producer, transit and consumer countries, would appear to be particularly effective in this regard. Interventions focused on specific trafficking routes are also likely to be effective if these routes have high edge betweenness centrality scores. This study contributes to extant understanding on the vulnerability of cocaine and heroin international trafficking networks, and, moreover, demonstrates that empirically-driven strategies are potentially more effective at interdicting international trafficking than non-strategic and non-coordinated interventions.

阻止国际毒品贩运:协调和针对性干预的网络方法

关于跨界封锁的影响以及不同类型的干预措施对国际毒品贩运的影响的文献相对较少。这项研究确定了可卡因和海洛因的主要贩运途径,并比较了有针对性的干预措施和不协调的干预措施所造成的破坏作用。它采用一种社交网络方法来识别可卡因和海洛因的贩运路线,然后模拟不同拦截策略对这两个贩运网络的影响。调查结果表明,根据国家在网络中各自的位置而不是根据所交换毒品的数量来确定目标国家,更有可能破坏毒品流动。进一步来说,在这方面,将执法资源集中在有几个进出人口贩运联系的国家,或在生产国,过境国和消费国之间进行调解的国家,似乎是特别有效的。如果这些路线的边际中心度得分较高,则针对特定贩运路线的干预措施也可能有效。这项研究有助于人们对可卡因和海洛因国际贩运网络的脆弱性已有了解,并且表明,以经验为依据的战略在阻止国际贩运方面比非战略性和非协调性干预措施更有效。在这方面似乎特别有效。如果这些路线的边际中心度得分较高,则针对特定贩运路线的干预措施也可能有效。这项研究有助于人们对可卡因和海洛因国际贩运网络的脆弱性已有了解,并且表明,以经验为依据的战略在阻止国际贩运方面比非战略性和非协调性干预措施更有效。在这方面似乎特别有效。如果这些路线的边际中心度得分较高,则针对特定贩运路线的干预措施也可能有效。这项研究有助于人们对可卡因和海洛因国际贩运网络的脆弱性已有了解,并且表明,以经验为依据的战略在阻止国际贩运方面比非战略性和非协调性干预措施更有效。
