Abstract

The paper reviews a number of challenges associated with reducing degradation and its related emissions through national approaches to REDD+ under UNFCCC policy. It proposes that in many countries, it may in the short run be easier to deal with the kinds of degradation that result from locally driven community over-exploitation of forest for livelihoods, than from selective logging or fire control. Such degradation is low-level, but chronic, and is experienced over very large forest areas. Community forest management programmes tend to result not only in reduced degradation, but also in forest enhancement; moreover they are often popular, and do not require major political shifts. In principle these approaches therefore offer a quick start option for REDD+. Developing reference emissions levels for low-level locally driven degradation is difficult however given that stock losses and gains are too small to be identified and measured using remote sensing, and that in most countries there is little or no forest inventory data available. We therefore propose that forest management initiatives at the local level, such as those promoted by community forest management programmes, should monitor, and be credited for, only the net increase in carbon stock over the implementation period, as assessed by ground level surveys at the start and end of the period. This would also resolve the problem of nesting (ensuring that all credits are accounted for against the national reference emission level), since communities and others at the local level would be rewarded only for increased sequestration, while the national reference emission level would deal only with reductions in emissions from deforestation and degradation.

摘要

本文回顾了在《联合国气候变化框架公约》政策下,通过国家 REDD+ 方法减少退化及其相关排放所面临的一些挑战。它提出,在许多国家,短期内可能更容易应对因当地社区为生计过度开发森林而导致的退化,而不是因选择性采伐或火灾控制导致的退化。这种退化程度较低,但持续时间较长,且发生在非常大的森林区域。社区森林管理方案不仅会减少退化,还会增强森林;此外,它们通常很受欢迎,也不需要重大的政治转变。因此,从原则上讲,这些方法为 REDD+ 提供了一个快速启动的选择。然而,由于库存损失和收益太小,无法使用遥感技术进行识别和测量,而且在大多数国家,几乎没有或没有森林清查数据,因此为低水平的、由当地驱动的退化制定参考排放水平是很困难的。因此,我们建议,地方一级的森林管理举措,如社区森林管理方案所推动的举措,应仅监测和核算实施期内碳储量的净增加量,方法是在实施期开始和结束时进行实地调查进行评估。这也将解决嵌套问题(确保所有的信用额度都与国家参考排放水平相对应),因为社区和地方一级的其他利益相关者将仅因固碳而获得奖励,而国家参考排放水平将仅处理因森林砍伐和退化导致的排放量减少。
