Community-based natural resource governance is increasingly valued by the leading international organizations that promote environmental conservation and sustainable development. At the same time, the ecosystems of the northeastern Andalusian mountains are intrinsically related to the long-standing presence of pastoralism and its different communal forms that have favored a very particular biocultural diversity and sustainable socio-ecological systems locally. Through a transdisciplinary anthropological and ecological study, we aimed to compare how different types of communal governance and pastoral mobilities impact pasturelands in the region. We focused on three contiguous mountain pastoral commons, those of Castril, Santiago de la Espada, and Pontones, which exhibit different forms of communal organization and two main transhumant types of mobility: long-distance and short-distance transhumance. We conducted long-term ethnographic fieldwork with year-round participatory observations of social life, pastoral practices, and governance systems, and performed botanical and soil analyses. As a general result, we found that local pastoralism positively impacts the environment. There were differences between commons and mobility regimes, with a positive impact related mainly to closer forms of cooperation between herders and daily guiding of flocks, along with seasonal long-distance transhumance, especially when the latter is combined with stricter formal community rules. Within the current context highly determined by public subventions, particularly from the EU, primarily directed at pastureland management’s administrative and economic aspects, local governance increasingly favors these methods over the conservation of traditional, sustainable uses of pastures. This innovative research marks the first step towards a sounder intertwining of anthropological and ecological approaches towards a more holistic understanding of pastoral commons in general and in the Mediterranean region specifically.
