亚洲的造林计划因缺乏优质种子而受到打击

[NEW DELHI] India, Indonesia, Malaysia and the Philippines will need 157 billion tree seeds in order to achieve a combined target of covering over 47.5 million hectares with trees by 2030, says a newstudy。

Published in the November edition of the journalDiversity,the study says that availability of quality seeds is important to achieving global森林restoration targets under the Bonn challenge — which aims at covering 150 million hectares of degraded and deforested lands with trees by 2020 and 350 million hectares by 2030.

Conservation在联合国气候峰会上，世界森林得到了提升COP26本月初，在格拉斯哥宣言由世界领导人和其他利益相关者提供金融的resources and the necessary knowledge and tools to protect forests and maintain their important ecosystem functions.

However,Riina Jalonen，，，，a co-author of the study and scientist at theBioversity Internationalresearch centre, Malaysia, says that investment in seeds and seedlings has been lagging far behind restoration commitments made over the past decade. “In fact, continued forest degradation has likely reduced seed availability instead,” she tellsscidev.net。

The researchers identified several constraints to forest landscape restoration in the studied countries, including limited supply of priority native species, poor quality control of seeds, and lack of information about the effects ofclimate changeon native species.

“High-quality, suitably adapted tree seed at volume is a key component for the implementation and long-term success of forest landscape restoration,” the researchers note.

Rekha Warrier, study co-author and scientist at the森林遗传和树繁殖研究所，，，，in Coimbatore, India, tellsscidev.net许多亚洲国家已经restoration targets to meet international commitments, but many of them have not “reached up to the expected level due to various bottlenecks”.

In Malaysia, the role of thegovernment在森林景观中，恢复大大有限，而在印度尼西亚，政府驱动的项目占主导地位。在菲律宾，当地社区缺乏参与森林修复计划和实施的参与。研究人员说，在所有这些系统中，种子的质量尚未保持。

这项研究的首席作者恩尼亚·博德哈德（Ennia Bosshard）说：“我们不需要重新发明轮子。”University of Exeter， 英国。“尽管目前在研究国家的国家一级存在重大局限性，但适合用途的种子系统的某些方面在某些国家 /地区运作良好，而不同利益相关者之间的知识转移有可能改善种子供应。透明

研究合着者Enrique Tolentino Jr，位于菲律宾林业与自然资源学院的教授，菲律宾大学洛斯巴尼奥斯说政府和社会应该联手实施政策旨在生产和提供足够数量的高质量种子的计划。

国家监测和预警中心在巴西自然灾害的科学家利亚纳·安德森（Liana Anderson）说，这项研究解决了一种森林修复的方法，该方法通过积极使用高质量种子来工作。她评论说，但是，可以考虑其他措施在没有大量投资的情况下进行森林修复。

Anderson says that the space between deforested areas and other forests’ core areas is important, as these areas could be used as a source of seeds for natural vegetation regeneration. “In some cases, especially in developing countries, the management of natural regeneration may be the most effective strategy to promote large-scale forest restoration,” Anderson tellsscidev.net。
