Ecosystem conservation and restoration activities are critical to reduce the vulnerability of biodiversity to climate change. Although these activities need to be evaluated objectively and systematically, they are rarely analyzed from a global, multidimensional and multivariable perspective. Here we present a methodology to quantify the environmental impact of landscape restoration using long-term and high-resolution satellite observations. For two restoration areas in Tanzania, we find 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 across their lifecycle, and support the reporting of comprehensive metrics to donors and partners. High quality satellite observations from commercial providers and space agencies are now achieving frequency, resolution, and accuracy that can effectively evaluate restoration activities.
