Open satellite data are key to data-driven evidence of human-environment interactions and built the basis for policy-relevant information in the domain of sustainable development. For instance, actions to avoid deforestation or to support the increase of carbon stocks through the use of agroforestry systems, depend on geospatial information products. One example is the project “Impact of terminated Payments for Ecosystem Services (PES) on carbon stocks, deforestation, collective action and intrinsic motivations for conservation” (IMPACTED), which is evaluating several long-term aspects of asset-building PES projects in Mozambique. This evaluation is supported through Earth Observation based impact monitoring, conducted by Remote Sensing Solutions GmbH. In this project, we use vegetation seasonality-based mapping methods and develop cutting edge mapping algorithms derived from open remote sensing data sets, such as Landsat Satellite Mission, jointly managed by NASA and the U.S. Geological Survey, and Sentinel Missions from Copernicus.
