DataSheet1_Quantifiable impact: monitoring landscape restoration from space. A regreening case study in Tanzania.pdf

The impact of ecosystem conservation and restoration activities are rarely monitored from a global, multidimensional and multivariable perspective. Here we present an approach to quantify the environmental impact of landscape restoration using long-term and high-resolution satellite observations. For two restoration areas in Tanzania, we can likely attribute an increase in the amount of water retained by the soil (∼0.01 m³ m⁻³, ∼13% average increase), a soil temperature drop (∼-0.5°C) and an increase in surface greenness (∼50% average increase) in 3.5 years. These datasets illuminate the impact of restoration initiatives on the landscape and support the reporting of comprehensive metrics to donors and partners. Satellite observations from commercial providers and space agencies are now achieving the frequency, resolution, and accuracy that can allow for the effective evaluation of restoration activities.

生态系统保护与恢复活动的环境影响往往缺乏全球性、多维度和多变量的监测。本研究提出了一种利用长期高分辨率卫星观测数据量化景观恢复环境影响的途径。针对坦桑尼亚的两个恢复区域，我们可能将土壤保持水量增加（约0.01 m³ m⁻³，平均增幅约13%）、土壤温度下降（约-0.5°C）以及地表绿色度增加（平均增幅约50%）在3.5年内归因于恢复活动。这些数据集揭示了恢复项目对景观的影响，并支持向捐赠者和合作伙伴报告全面的指标。来自商业供应商和航天机构的卫星观测现在达到了能够有效评估恢复活动的频率、分辨率和准确性。
