Headline: Epistemological and ethical understandings of access and allocation in Earth System Governance. A 10-year review of the literature

“Access and allocation” is one of the five analytical problems identified as key for analysing earth system governance in the first Earth System Governance Science and Implementation Plan officially published in 2009. Ten years later and with a new Science and Implementation Plan in place, it is time to take stock. Therefore, this paper addresses the question: What does a decadal review of the Earth System Governance literature tell us about how to conceptualize and define access and allocation, what ethical norms and epistemologies underlie access and allocation research, and what does Earth System Governance scholarship reveal about the interplay between access and allocation and other norms? We find that: (a) there is a relatively small body of the Earth System Governance literature on access and allocation, albeit growing; (b) this literature is largely empirical and dispersed across a variety of topics; and (c) there is a diversity of ethical norms and principles emphasized in Earth System Governance scholarship, but the dynamics between different forms of access and related implications for allocation are relatively underexplored. In light of these findings and with a new Earth System Governance Science and Implementation Plan in place, this paper highlights key areas for further research and development.
