可持续管理完整的热带泥炭地对于减缓气候变化、保护生物多样性和支持当地社区的生计至关重要。在这里，我们探讨了可持续的水果收获是否可以通过增加亚马逊河流域280万公顷碳密度最高的生态系统（秘鲁东北部的低地泥炭地）的水果产量和收入来支持这些相关的目标。flexuosais雌雄异株，水果通常是通过砍伐女性棕榈收获;因此，女性棕榈的比例提供了一个很好的指标的健康stand. Across 93广泛分布的网站，我们发现，女性棕榈的比例增加与旅行时间的城市市场，总体而言，水果收获了目前的潜在产量和收入从这个资源减半。然而，在通过攀缘收获果实的地方发现了更多的雌性棕榈树。我们估计，整个区域范围内的攀缘植物的吸收最终可以增加51%的潜在水果产量，并将其总价值增加到6200万± 2820万美元。这些研究结果表明，在新热带区森林中不可持续的资源开采成本很高，并概述了保护和可持续利用地球上最富碳景观之一的可行途径。
Sustainable management of intact tropical peatlands is crucial for climate change mitigation, for biodiversity conservation and to support the livelihoods of local communities. Here, we explore whether sustainable fruit harvesting fromMauritia flexuosapalms could support these linked goals by increasing fruit production and incomes across the 2.8 million hectares of the most carbon-dense ecosystem in Amazonia: the lowland peatlands of northeastern Peru.M. flexuosais dioecious, and fruits are typically harvested by felling female palms; the proportion of female palms therefore provides a good indicator of the health of a stand. Across 93 widely distributed sites, we found that the proportion of female palms increases with travel time to the urban market, and overall, fruit harvesting has halved the current potential production and income from this resource. However, significantly more female palms are found where fruit are harvested by climbing. We estimate that region-wide uptake of climbing could eventually increase potential fruit production by 51% and increase its gross value to US$62 ± 28.2 million yr–1. These findings demonstrate the high cost of unsustainable resource extraction in Neotropical forests and outline a practical path to conserve and sustainably exploit one of the most carbon-rich landscapes on the planet.
