This report is part of the EJP SOIL SERENA project. It presents the way some stakeholders have been involved in the project to validate mapping products of soil-based ecosystem services and soil threats, which have been produced by some harmonised cookbooks. The cookbooks are first presented and their concern: as far as soil threats are concerned, and as far as soil-based ecosystem services are concerned. A cookbook for an evaluation of bundles is also presented. The list of countries which have evaluated the different products is then precised. The results of the evaluation by stakeholders are commented all together, without any relation to a specific country. They demonstrate that the results are more likely understood by scientists than by policy makers or farmers. For the latter, the scale of the maps are not relevant with their own interest. The maps of erosion, SOC loss and soil sealing seem to be more easily understood by the stakeholder that the GHG regulation, and the bundles, with which stakeholders are not familiar. In a forthcoming version of the report, the assessment of EU-scale products will be presented.
