Description This document is related to Deliverable 3.1 of the Man0EUvRE project, in which we report modelling activities of nine case studies from various countries. Each case study addresses a question from a regional perspective while considering the general assumptions of the consortium through established scenarios. We follow a consistent reporting format across all case studies, allowing readers who are interested in a specific region or question to skip other cases without losing essential context. Funding This research was funded by CETPartnership, the European Partnership under Joint Call 2022 for research proposals, co-funded by the European Commission (GA N°101069750) and with the funding organisations listed on the CETPartnership website.
