WP4 (Participatory appraisal of vulnerability and performance of value chains) set out to analyse diverse mountain Value Chains (VCs) as assemblages of practices within nested socio-ecological systems across Europe. The focus is on the Value Chain assemblage (VC-A) incorporating a focal VC and additional VCs that interact within specific mountain territories and rely on territorial capital. This deliverable considers if the VC-A is vulnerable to threats; and how these VC-A can be made resilient, whilst supporting sustainable mountain development. The deliverable synthesises insights from the ongoing youth engagement work (England and Creaney, In Progress); and analyses of vulnerabilities of the land use systems (González-Moreno et al., 2022) of the VC-A (Zagata et al., 2023); and the participatory analysis of the VC-A (Blackstock et al., 2022).
