Biodiversity targets were prominent at the Tenth Conference of the Parties to the Convention on Biological Diversity (CBD). Having failed to reach the CBD's 2010 target, delegates debated the nature of targets, details of specific targets, and how to avoid failure in 2020. As part of a group of seventeen researchers conducting a collaborative event ethnography at COP10, we draw on observations made during negotiations of the CBD Strategic Plan and at side events to analyze the production of the 2020 targets. Once adopted, targets become “naturalized,” detached from the negotiations that produced them. Drawing on insights from science and technology studies, we analyze the interaction of science and politics during negotiations and discuss what targets do within the CBD and the broader global conservation governance network.

This special issue introduces readers to collaborative event ethnography (CEE), a method developed to support the ethnographic study of large global environmental meetings. CEE was applied by a group of seventeen researchers at the Tenth Conference of the Parties (COP10) to the Convention of Biological Diversity (CBD) to study the politics of biodiversity conservation. In this introduction, we describe our interests in global environmental meetings as sites where the politics of biodiversity conservation can be observed and as windows into broader governance networks. We specify the types of politics we attend to when observing such meetings and then describe the CBD, its COP, challenges meetings pose for ethnographic researchers, how CEE responds to these challenges generally, and the specifics of our research practices at COP10. Following a summary of the contributed papers, we conclude by reflecting on the evolution of CEE over time.

The Convention on Biological Diversity (CBD) continues to promote marine protected areas (MPAs) as a preferred tool for marine biodiversity conservation, in spite of concerns over their effectiveness and equity. However, explanations for this consensus on the utility of MPAs focus primarily on their measurability and ignore the ways in which they are conceptualized through ongoing governance processes. Drawing on the results of collaborative event ethnography at the Tenth Conference of the Parties to the CBD, this paper adopts the concepts of boundary objects and scalar narratives to analyze the ways in which consensus on MPAs is produced, in spite of conflicting understandings of MPA forms and functions. Both a local narrative of participatory MPAs and a global narrative of science driven high seas conservation articulate a regional scale as ideal for MPA governance, although with different priorities. Ultimately, consensus at the CBD is enabled only by accommodating competing visions of MPAs.
