This publication/report contains a review of scientific knowledge (bibliography, expert opinions, current EU projects), an inventory of the technological resources mobilised (vectors, sensors, current and planned products, services), and the identification of obstacles to greater use of Earth observations for soil monitoring and measurement needs to reduce/minimise these difficulties. “The PREPSOIL (Preparing for the "Soil Deal for Europe" Mission) project facilitates the deployment of the Mission across European regions. This will be achieved through the co-creation and roll out of tools and spaces for interaction, knowledge-sharing and co-learning, as well as stocktaking and dialogue to understand how regional assessment of soil needs, supported by harmonised monitoring mechanisms, can then lead to action in living labs and light houses for soil health.”
