Villamayor-Tomas, Sergio

Panel Chair/Moderator

Panel 12.18. The International Journal of the Commons (IJC): A community-based journal
co-Chairs: Sergio Villamayor-Tomas and Maria Claudia Lopez

In this session, the editors-in-chief of the International Journal of the Commons will moderate a deliberative conversation among attendants to take stock of the state of the publication industry (increasing dominance of publishing companies, publication rates, open access transformations, publish or perish motto…) and to discuss the position of the IJC in this context. The session will attempt to gather new ideas and energies around how to best serve and build the commons community.

Over the last few decades, the diversity of governance solutions proposed by scientists and policymakers for addressing mounting environmental problems has increased substantially. The traditional trichotomy of state, market and community governance has been replaced by a new interest in hybrid regimes in recognition that no single governance mode possesses the capabilities to address all current environmental problems. This paper takes stock of experiences that combine community and market-based governance solutions, or as we call them community-based environmental markets (CBEMs), to address environmental issues in a variety of resource management contexts. We first propose a classification system based on the authority held by communities and the type of good being transacted to identify four general classes of CBEMs. These include communal resource markets, communal service markets, collective resource markets and collective service markets. We then illustrate the utility of this classification system with a review of studies from the water, forest, pastures, fishery, agriculture and wildlife conservation sectors. We conclude with some hypotheses regarding the relative effectiveness of different types of CBEMs with respect to a range of social and environmental objectives.

What shapes different forms of governance and their performance, and is the concept of hybrid governance (hybrids) a promising pathway for improving the outcomes of governance, e.g. in environmental governance? Understanding these issues will improve our knowledge for crafting better governance towards desirable outcomes. A natural place to start such work is polycentric governance. Thus, this paper aims to advance on unpacking the black box of coordination in polycentric governance. As it unfolded we found that based on our definition of hybrids as overlapping modes of coordination hybrids dominate empirically. Thus, our work maps distinct hybrids, explore their emergence and determining factors as well as analyze their performance. The paper suggests a positive approach to understanding hybrids. As starting point for conceptualizing hybrids s we use the Institutional Analysis and Development (IAD) framework which is strongly related to and therefore compatible with polycentric. We illustrate its application through engagement into five contrasting, illustrative cases in which we identified four different types of hybrids as starting points for further theorizing. We end on identifying types of hybrids and contextual factors shaping them. We suggest the identification of hybrids as future research agenda for unpacking the inner workings of polycentric governance. The paper is based on an edited volume developed among proponents of this abstract and a number of scholars in the field of natural resource governance. We suggest that hybrids are stratified across temporal scales and nested across different levels of institutional order, addressing day to day coordination which is nested in institutions in larger scales of societal organization that structure these modes . Beyond the three modes of governance that overlap in hybrids, we find that the distinction of formal, state-backed legitimization of governance as opposed to informal, community-backed legitimization of governance of component modes of coordination provides a further important dimension of hybrids. The emergence and performance of hybrids depends on social-ecological context configurations.
