需要有效的恢复规划工具来缓解全球碳和生物多样性危机。已发表的恢复潜力空间评估往往尺度较大或分辨率粗糙，不适合当地采取行动。使用坦桑尼亚的案例研究，我们介绍了一个系统的方法，通知景观恢复规划，估计空间变化的成本效益，恢复方法，物流，生物量建模和不确定性映射的基础上。我们发现，在53000平方公里的区域中，77.7%的生物量有恢复的潜力，但潮湿森林生物量存在一些自然空间不连续性，这是以前人为原因造成的。大部分生物量不足的地区（80.5%）通过被动或辅助自然更新可以恢复。然而，种植的累积生物量收益超过了最初高昂的实施成本，这意味着在适用的情况下，这种方法产生了更大的长期投资回报。考虑到生态、资金和其他不确定性，持续成本效益最高的25%的地点位于保护区和/或中度退化的潮湿森林和稀树草原内。农业生态镶嵌体的生物量赤字高，但几乎没有成本效益的恢复潜力。需要进行社会经济研究，以便为在这些领域实现环境和人类发展目标的行动提供信息。我们的研究结果突出了长期景观恢复投资和热带稀树草原和森林单独处理的价值。此外，它们与先前断言的东非低恢复潜力相矛盾，强调了我们在热带地区确定恢复机会的区域方法的重要性。这篇文章是“了解森林景观恢复：加强联合国生态系统恢复十年的科学基础”主题的一部分。
Effective restoration planning tools are needed to mitigate global carbon and biodiversity crises. Published spatial assessments of restoration potential are often at large scales or coarse resolutions inappropriate for local action. Using a Tanzanian case study, we introduce a systematic approach to inform landscape restoration planning, estimating spatial variation in cost-effectiveness, based on restoration method, logistics, biomass modelling and uncertainty mapping. We found potential for biomass recovery across 77.7% of a 53 000 km2 region, but with some natural spatial discontinuity in moist forest biomass, that was previously assigned to human causes. Most areas with biomass deficit (80.5%) were restorable through passive or assisted natural regeneration. However, cumulative biomass gains from planting outweighed initially high implementation costs meaning that, where applicable, this method yielded greater long-term returns on investment. Accounting for ecological, funding and other uncertainty, the top 25% consistently cost-effective sites were within protected areas and/or moderately degraded moist forest and savanna. Agro-ecological mosaics had high biomass deficit but little cost-effective restoration potential. Socio-economic research will be needed to inform action towards environmental and human development goals in these areas. Our results highlight value in long-term landscape restoration investments and separate treatment of savannas and forests. Furthermore, they contradict previously asserted low restoration potential in East Africa, emphasizing the importance of our regional approach for identifying restoration opportunities across the tropics. This article is part of the theme issue ‘Understanding forest landscape restoration: reinforcing scientific foundations for the UN Decade on Ecosystem Restoration’.
