ONF International, an institutional body in matters of international cooperation projects in the forest management areas need tools to help people to empower their decision. The Open-Source solution help us to find a set of tools to develop a web-based platform to interact with different stakeholder and help them on their decision about forest management. Especially we used and fund some component of QGIS, py-qgis-server, py-qgis-wps, R through a work with 3Liz using Lizmap. A successful work, funded by the Climate KIC was done on building a platform to help stakeholder on a forest restoration process on the Paragominas municipality in Brazil.
