Two concurrent trends are contributing towards a much broader view of forest conservation. First, the appreciation of the role of forests as a nature-based climate solution has grown rapidly, particularly among governments and the private sector. Second, the spatiotemporal resolution of forest mapping and the ease of tracking forest changes have dramatically improved. As a result, who does and who pays for forest conservation is changing: sectors and people previously considered separate from forest conservation now play an important role and need to be held accountable and motivated or forced to conserve forests. This change requires, and has stimulated, a broader range of forest conservation solutions. The need to assess the outcomes of conservation interventions has motivated the development and application of sophisticated econometric analyses, enabled by high resolution satellite data. At the same time, the focus on climate, together with the nature of available data and evaluation methods, has worked against a more comprehensive view of forest conservation. Instead, it has encouraged a focus on trees as carbon stores, often leaving out other important goals of forest conservation, such as biodiversity and human wellbeing. Even though both are intrinsically connected to climate outcomes, these areas have not kept pace with the scale and diversification of forest conservation. Finding synergies between these 'co-benefits', which play out on a local scale, with the carbon objective, related to the global amount of forests, is a major challenge and area for future advances in forest conservation.
两个同时发生的趋势使人们对森林保护有了更广泛的认识。首先,森林作为一种基于自然的气候解决方案的作用得到了迅速认可,尤其是在政府和私营部门中。其次,森林测绘的时空分辨率和跟踪森林变化的便捷性有了显著提高。因此,谁来为森林保护买单以及如何买单正在发生变化:以前被认为与森林保护无关的部门和个人现在发挥着重要作用,需要对森林保护负责,并激励或强制他们保护森林。这种变化需要并刺激了更广泛的森林保护解决方案。评估保护干预措施的结果的需要,推动了利用高分辨率卫星数据进行复杂计量经济学分析的发展和应用。与此同时,对气候的关注,加上可用数据和评估方法的性质,阻碍了对森林保护更全面的认识。相反,它鼓励人们关注树木作为碳储存库,而往往忽略了森林保护的其他重要目标,如生物多样性和人类福祉。尽管这两者与气候结果有着内在的联系,但这些领域并没有跟上森林保护的规模和多样化的步伐。在地方层面上发挥作用的这些“共同效益”与与全球森林数量相关的碳目标之间找到协同作用,是森林保护未来发展的主要挑战和领域。
