Nature-based Solutions (NbS) are increasingly recognized as key levers for climate change adaptation, offering benefits for both biodiversity and society—economic, cultural, and beyond—while enhancing socio-ecosystem resilience. However, their widespread adoption is often hindered by a lack of collaborative frameworks, which have been shown to play a crucial role in increasing NbS acceptance and preventing conflicts over their deployment within socio-ecosystems. Addressing this challenge requires approaches that foster co-construction with local stakeholders, ensuring that proposed solutions align with territorial specificities and community expectations. Living Labs, with their transdisciplinary and participatory research methodologies, provide valuable support in overcoming these barriers by creating structured spaces for dialogue, experimentation, and shared learning. In the Pays de la Meije (French Alps), the VivAlp Living Lab served as a framework for organizing a series of workshops where we aimed to: (1) co-identify candidate NbS and (2) co-construct evaluation criteria to guide their deployment, in collaboration with local stakeholders and residents. Our objective is to develop NbS deployment scenarios that account for both local constraints and adaptation goals, as defined through the co-construction process. Among the NbS considered, two were particularly targeted: the planting of hedgerows and trees, and the maintenance of mown meadows in future landscape management. Our participatory modeling approach relies on three key components: (1) mapping ecosystem services to inform local current and future needs, (2) identifying spatial and socio-economic constraints within the landscape (e.g., linked to agricultural practices), and (3) eliciting stakeholder preferences regarding NbS benefits and trade-offs. By integrating this information, we developed a set of scenarios that directly address local needs, constraints, and preferences. These outcomes provide concrete guidance on optimal NbS deployment locations, helping to bridge the gap between conceptual discussions and actionable implementation. They also serve as a valuable basis for structuring future discussions on funding mechanisms, governance, and long-term monitoring, ensuring that NbS integration into the landscape is both effective and well-supported.
