摘要

摘要 审查目的 本次审查的目的是确定当前在亚马孙地区有效实施可持续森林经营所面临的挑战。其次,将这些挑战简明扼要地归纳为定义明确的综合领域。然后确定文献中提供的解决方案。最后,在进行全面评估后,提出可能的方向,以帮助林业工作者、土地管理者、研究人员和伐木者就实现亚马逊可持续森林经营的必要条件达成共识。 最新发现 非法采伐是对林业部门信誉的普遍威胁,巴西亚马逊地区38%的采伐面积都是非法采伐,这种不公平的竞争优势破坏了合法的采伐作业。解决方案之一是应用近红外光谱技术,该技术在确定树种和潜在原产地方面大有可为。同样的技术也在不断改进,以用于区分绿色能源中使用的伐木残留物的物种,因为有些行业对物种不感兴趣,而同样的物种可能仍可用于能源生产。最近的模型显示,巴西亚马逊地区的伐木周期太短,砍伐强度太高。此外,现在可以通过放射性碳分析确定树龄,从而确定可持续的砍伐周期。 总结 如果不加强现场森林检查和确定木材来源,非法采伐将有增无减。通过减少伐木基础设施覆盖面的新模式和计划,可以轻松减少伐木对林木造成的破坏。为避免木材储备枯竭,必须延长伐木周期,以适应亚马逊地区许多物种生长缓慢的实际情况。

The Challenges of Sustainable Forest Operations in Amazonia

Abstract

Purpose of Review

The goal of this review was to determine what constitutes current challenges in effectively implementing sustainable forest operations in Amazonia. Next, succinctly characterize these challenges into comprehensive well-defined areas. Then ascertain the solutions provided in the literature. Lastly, after a thorough assessment, present potential directions to assist foresters, land managers, researchers, and loggers to build a consensus on what is necessary to achieve sustainable forest operations in Amazonia.

Recent Findings

Illegal logging is a pervasive threat to the credibility of the forest sector with 38% of all logged area in the Brazilian Amazon illegal, which undermines legitimate logging operations through an unfair competitive advantage. One solution is the application of near infrared spectroscopy which has shown promise in determining species and potentially the region of origin. This same technology is also being refined for utilization in species differentiation between logging residues used in green energy, as some industries are species averse, whereas the same species may still be viable for energy generation. Recent models reveal that in the Brazilian Amazon the logging cycle is too short and the cutting intensity too high. Moreover, tree age estimation, which is difficult in many Amazonian species, can now be determined through radiocarbon analysis to determine sustainable cutting cycles.

Summary

Without increased onsite forest inspections and determination of timber origin, illegal logging will continue unabated. Stand damage from logging can easily be reduced through new models and programs that reduce logging infrastructure coverage. To avoid the depletion of timber stocking, the logging cycle must be increased to coincide with the slow growth realities of many species in the Amazon.

期刊介绍: Current Forestry Reports features in-depth review articles written by global experts on significant advancements in forestry. Its goal is to provide clear, insightful, and balanced contributions that highlight and summarize important topics for forestry researchers and managers. To achieve this, the journal appoints international authorities as Section Editors in various key subject areas like physiological processes, tree genetics, forest management, remote sensing, and wood structure and function. These Section Editors select topics for which leading experts contribute comprehensive review articles that focus on new developments and recently published papers of great importance. Moreover, an international Editorial Board evaluates the yearly table of contents, suggests articles of special interest to their specific country or region, and ensures that the topics are up-to-date and include emerging research.
