Forest restoration is a strategy to reverse forest loss and degradation. We overviewed deforestation in the period 1975–2018 in the Brazilian Amazon and the projects, techniques, and scientific publications conducted to recover forest in the area by 2019. We used GIS to assess forest loss and a systematic data collection gathered from 12 universities, five major environmental agencies, and an ad-hoc bibliographic survey that rendered information from 405 restoration projects and 152 published studies. The Brazilian Amazon has undergone an accelerated deforestation in the last 43 years, resulting in 20% (788,353 km2) of its territory deforested by 2018. Deforestation rate was 27,033 km2 yr−1 between 1975 and 1987 and 14,542 km2 yr−1 between 1988 and 2018 (1.97% yr−1 of forest loss between 1975 and 2018). In 2018, 41 Amazonian municipalities were classified as priority areas for monitoring and control deforestation and 21 additional municipalities were deemed as areas with controlled deforestation. Our survey identified 405 projects of forest restoration in 191 municipalities between 1950 and 2017. The majority (229) of these projects used seedling planting as the main forest restoration technique. Forest restoration projects based upon agroforestry systems (144), assisted natural regeneration (27), and natural regeneration (5) were also identified. Despite a considerable number of projects and publications, the region still lacks scientific studies that reinforce the choice of best practices for forest restoration, and the information currently available is not enough to quantify what has already been recovered or the potential area to be restored.

巴西亚马逊地区森林流失与恢复概述

森林恢复是扭转森林丧失和退化的战略。我们概述了巴西亚马逊河地区1975-2018年的森林砍伐情况,以及为在2019年前恢复该地区森林而开展的项目,技术和科学出版物。我们使用GIS评估了森林损失,并从12所大学,5所大学收集了系统的数据主要的环保机构,以及一份临时书目调查,该调查从405个修复项目和152个已发表的研究中获得了信息。巴西亚马逊经历过去43年加速砍伐,导致20%(788353公里2通过2018砍伐森林砍伐率其领土)中的溶液27033公里2 年-1 1975和1987和14542公里之间2 年-1 1988和2018(1.97%年之间-1(1975年至2018年之间的森林损失)。2018年,有41个亚马孙城市被列为监测和控制森林砍伐的优先区域,另外21个城市被视为森林砍伐可控制的区域。我们的调查确定了1950年至2017年间191个城市中的405个森林恢复项目。这些项目中的绝大部分(229个)都以种树作为主要的森林恢复技术。还确定了基于农林业系统的森林恢复项目(144),辅助自然再生(27)和自然再生(5)。尽管有大量的项目和出版物,但该地区仍然缺乏科学研究,无法加强对森林恢复最佳实践的选择,
