巴西的大豆禁令巩固了世界上最大的贸易商的承诺，即停止从2006年7月后砍伐森林的产区购买大豆。其目的是从大豆供应链中消除森林砍伐，并阻止亚马逊生物群森林丧失的主要驱动因素之一。在这项研究中，我们调查了2004年至2014年期间在财产层面上砍伐森林的变化。目的是审查直接和间接砍伐森林，即在马托格罗索州马托格罗索州的亚马逊地区为大豆扩张而砍伐森林，定义为财产内流离失所和跨块流离失所。马托格罗索州是巴西亚马逊主要的大豆生产州。我们使用可公开获得的财产和土地使用数据来量化与农田扩张相关的森林砍伐。与之前的研究类似，我们发现大豆种植的直接森林砍伐在大豆禁令实施后有所下降。此外，我们的分析表明，间接砍伐森林在大豆禁令实施之前就已经发生，并在第一阶段分析之后减少。然而，间接砍伐森林在最近几个时期略有增加，加上直接砍伐森林的减少，间接砍伐造成了与大豆种植相关的森林砍伐的一半以上。虽然我们承认大豆砍伐的总体减少，但我们的结果表明，鉴于自2013年以来巴西亚马逊地区砍伐森林的趋势不断增加，应在大豆禁令范围内解决间接砍伐问题。这可以通过零财产砍伐森林的承诺以及通过加强供应链参与者、大豆和牛肉采购公司与旨在控制砍伐森林的联邦政策之间的整合来实现。
Brazil's Soy Moratorium solidified the world's largest traders' commitment to stop soybean purchases from production areas deforested after July 2006. The aim was to remove deforestation from the soybean supply chain and halt one of the main drivers of forest loss in the Amazon biome. In this study, we investigated changes in deforestation at the property-level for the period 2004 to 2014. The objective was to examine direct and indirect deforestation, defined as on-property displacement and cross-parcel displacement deforestation for soybean expansion in the Amazon region of Mato Grosso, the leading soy-producing state of the Brazilian Amazon. We used publicly available property and land use data to quantify deforestation associated with cropland expansion. Similar to previous studies, we found that direct deforestation for soybean expansion declined following the implementation of the Soy Moratorium. Moreover, our analysis suggest that indirect deforestation occurred already before the implementation of the Soy Moratorium, and decreased following the first period of analyses. However, slight increases of indirect deforestation in the more recent periods, combined with decreasing direct deforestations rendered indirect deforestation to be responsible for more than half of the deforestation associated with soybean expansion. While we acknowledge the overall reduction of deforestation for soybean, our results suggest, given the increasing trends of deforestation in the Brazilian Amazon since 2013, to address indirect deforestation within the Soy Moratorium. This may be achieved by zero-property-deforestation commitments and by strengthening the integration between supply-chain actors, the soybean and beef purchasing companies and the federal policies aiming to control deforestation.
