Abstract
Sustainable livestock management plays a crucial role in food production, climate change mitigation, and cultural preservation. Our study aimed to identify and analyse the diversity of social-ecological conditions that characterize extensive livestock systems in southern Patagonia. We integrated data collected from interviews and secondary sources and analysed data using hierarchical cluster analysis and non-metric multidimensional scaling to identify distinct ranching types. A qualitative analysis of key informant interviews identified key social-ecological changes for each type. The results emphasize the impact of administration, production, and biophysical factors on shaping different livestock ranching schemes. Further, we identified three significant social-ecological changes driving the dynamics of these systems, including shifts from (1) sheep to cattle ranching, (2) domestic to feral cattle ranching, and (3) landowners to tenant land managers. These findings have implications for policymakers seeking to develop strategies tailored to diverse realities, ensuring the sustainability of livestock systems in Tierra del Fuego.
