Interactions with global markets offer development opportunities for Indigenous communities. They also place pressure on the natural resources that communities depend upon for their livelihood and, in many cases, their political and cultural autonomy. These markets often interact with family-based enterprises embedded within commons, with important implications for the social relationships and shared territorial resources that characterise such regimes. In this paper, we analyse the relationships that exist between commons, global markets, and small-scale family enterprises, using the case of mezcal production—an alcoholic beverage made from agave—in an Indigenous community in Oaxaca, Mexico. Most mezcal production is organized at the family level; yet the raw materials and inputs (land, wild agave, firewood, water) necessary for making mezcal are held communally and regulated by locally-crafted institutions. Empirical data show that as family enterprises engage with an emergent global market for mezcal, the commons become essential for not only protecting territorial resources but also maintaining a degree of autonomy from powerful global markets and value chains. However, this requires substantial investment in monitoring and enforcement, and for community members to value sustainable commons management over short-term economic self-interest. To seek autonomy while participating in global markets, producer families also join together to develop cooperative strategies to access markets on better terms.
