多样的保护工作不断扩大在全球范围内,即使在压力增加农业生产。一个引人注目的例子是供应链协议欺骗的亚马逊森林砍伐森林减少了80%,从2000年代早期(27772平方公里)2015(6207平方公里)。然而,这些保护措施的评估通常只关注亚马逊生物群落内的影响,而影响波及其他领域(例如,从一个区域到另一个环境压力位移)很少被考虑在内。忽略溢出效应可能导致偏见甚至错误的结论关于这些保护措施的有效性,因为隐藏成本目标区域之外的保护可能会抵消成就。因此重要的是要评估这些供应链协议的溢出效应。在这项研究中,我们使用了两个(即供应链协议。,Soy Moratorium and zero-deforestation beef agreement) implemented in the Amazon biome as examples and evaluated their spillover effects to the Cerrado. To achieve a holistic evaluation of the spillover effects, we adopted the telecoupling framework in our analysis. The application of the telecoupling framework includes the interactions between distant systems and extends the analytical boundaries beyond the signatory areas, which fill the gap of previous studies. Our results indicate that the supply-chain agreements have significantly reduced deforestation by half compared to projections within the sending system (i.e., Pará State in the Amazon, which exports soybeans and other agricultural products), but at the cost of increasing deforestation in the spillover system (i.e., a 6.6 time increase in Tocantins State of the Cerrado, where deforestation was affected by interactions between the Amazon and other places). Our study emphasizes that spillover effects should be considered in the evaluation and planning of conservation efforts, for which the telecoupling framework works as a useful tool to do that systematically.
