Promoting territorial biomass circularity can foster sustainable rural development by reducing dependence on imports, mitigating environmental impacts, and engaging communities in resource management (van Zanten et al., 2019; Muscat et al., 2021). However, stakeholders have limited access to tools for identifying potentials, codesigning local taillored biomasse circularity and assess its impacts especially in rural areas in the Global South. Using Living Lab approaches in rural areas is a promising way to address these challenges. Our study try to fill this gap developping a transdisciplinary and participatory approach in two rural Living Labs in Madagascar's Central Highlands.
