Abstract Evidence shows that there is a close link between the intensification of shifting cultivation (SC) and the Amazon forest resilience. However, SC, to this day, is a widely implemented agricultural practice around the Amazon region due to its cultural, social, and economic relevance. In pristine indigenous communities, which have not experienced Western influence, SC will continue to be the main livelihood as part of the conservation of a patrimony of the humanity. Nevertheless, the main adverse effects of SC on ecosystems (i.e. forest degradation), particularly on Amazon forests, are our grounds to justify the implementation of public policies aiming to the substitution by agroforestry systems (AFS) as a sustainable food system. In this context, we propose linking AFS to Reducing Emissions from Deforestation and forest Degradation (REDD+ strategies) in shifting cultivation landscapes where there is high local-scale expansion and intensification of SC. AFS has higher potential as sustainable food systems for degraded forest rehabilitation and reduction of the expansion and intensification of SC. Consequently, AFS reduce deforestation of new forest areas for SC, meanwhile, sustainable management of second-growth forests could also be implemented through improved fallows, increasing the planting density of long-cycle agroforestry tree species. AFS should be implemented in local communities, in particular, those undergoing human-modified Amazon landscapes, where there is a high intensification of SC.

政策论坛：亚马逊的转移种植和农林业：REDD+ 的前提

摘要 证据表明，轮垦（SC）的集约化与亚马逊森林恢复力之间存在密切联系。然而，直到今天，由于其文化、社会和经济相关性，SC 仍是亚马逊地区广泛实施的农业实践。在未受西方影响的原始土著社区中，作为保护人类遗产的一部分，南卡罗来纳州将继续成为主要生计。尽管如此，SC 对生态系统（即森林退化），特别是对亚马逊森林的主要不利影响，是我们实施旨在由农林业系统 (AFS) 替代作为可持续粮食系统的公共政策的理由。在这种情况下，我们建议将 AFS 与减少来自森林砍伐和森林退化的排放（REDD+ 策略）联系起来，在轮垦景观中，SC 的局部规模扩大和集约化程度很高。AFS 作为可持续粮食系统具有更大的潜力，可用于退化森林的恢复和减少 SC 的扩大和集约化。因此，AFS 减少了南卡罗来纳州新林区的森林砍伐，同时，还可以通过改善休耕来实现次生林的可持续管理，增加长周期农林树种的种植密度。AFS 应该在当地社区实施，特别是那些经历人类改造亚马逊景观的社区，那里的 SC 高度集约化。
