Numerous authors from various disciplines have underlined the importance of Indigenous Peoples' and Community Conserved Territories and Areas (ICCAs) for assuring the livelihoods of local populations whilst conserving the environment. The agdal is probably Morocco's best example of such an institution. Nevertheless they have always existed within the context of change and currently are experiencing major transitions. Detailed ethnographic studies of the socio-ecological drivers of these processes of change in agdals are scarce. Based on the particular case of the agdal of Yagur in the Mountain Mesioui tribal territory (High Atlas of Morocco), this article will analyse contemporary transformations. These dynamics are inherent to small-scale societies' ICCAs, even if they have most often been described as isolated, autarchic and mutable only under external pressure. From the case of the agdal of Yagur, we show how non-local processes are only part of the picture, and that the transformation of agdal forms are also related to key internal drivers, entailing a greater degree of agency by local actors than is usually given in the literature. At the same time, placing our analysis within a broader social anthropological framing, we provide a detailed actor-centred analysis that situates agents and local power relations within their institutional and cultural context while explaining how these same micropolitics of natural resource management articulate with and within wider global scales.
