确定的全球森林恢复热点

[NAIROBI] Africa, Central and South America and Southeast Asia have the greatest potential to restoreforestsand reap their benefits, a学习says.

The study adds that of 57 commitments to restore 170 million hectares of forests by 2030, 80 per cent focus on tropical developing countries. But identifying landscapes known as hotspots where forest restoration could lead to greatest potential benefits is a challenge, according to experts.

“迫切需要将森林带回，以防止物种灭绝，改善水安全，减轻森林气候变化through carbon storage, and provide habitats for climate change adaptation,” says Robin Chazdon, a professor in the Department of Ecology and Evolutionary Biology at the University of Connecticut, United States, and co-author of the study published last week (3 July) in theScience Advances杂志。

“迫切需要将森林带回到有助于防止物种灭绝，改善水安全，减轻气候变化的地区。”

Chazdon告诉SciDev.Net在全球范围内需要恢复的许多领域，但是他们检查了最有益和可行的恢复结果，预计将使国家能够开始专注于热点。

这项持续了四年̶2015年至2018年的研究通过考虑广泛的好处（不仅是树木覆盖和碳存储）来使用跨学科的方法，还包括包括经济因素（例如受农业生产影响的土地机会成本）。

研究人员使用七个数据集确定了低地热带雨林景观中的热点，并创建了从零到一个的值梯度，以表示恢复机会得分。

该研究援引布隆迪，马达加斯加，卢旺达，南苏丹，多哥和乌干达的研究，“平均恢复机会得分最高的前六个国家是最高的恢复机会得分。”

“The study really highlights the high potential for successful forest restoration outcomes in these African countries,” Chadzon adds.

The study also cites Brazil, Colombia, India, Indonesia and Madagascar as the five nations with the largest hotspot areas.

Chadzon tellsSciDev.Net那governmenT机构，非政府组织，政策制定者，从业人员，研究人员和公众需要注意研究结果。

查德Zon说：“我们希望我们的研究能够激发人们对长期成功的新政策重点以及具有多种利益并保持许多兴趣的结果。”

Louis Verchot, research leader for landscapes restoration at the International Center for Tropical Agriculture, Colombia, says there is huge potential for tropical forest restoration and it would be a beneficial to the global climate system and tropical countries.

“In many places in Africa, biodiversity is an important source for benefits such as protein, medicines, building materials [and] water. It is an important part of the resilience of African landscapes by providing food during lean times, includingdroughts,”他告诉SciDev.Net.

他解释说，我们需要一种更合理的土地使用方法来整合当地社区的不同需求，国家发展的机会，生物多样性生态系统和景观的缓冲效应，并补充说，policymakersin developing countries need to pay more attention as such nations are more vulnerable to negative outcomes of deforestation.
