Scales of integration for sustainable development governance

Efforts at integration are central in the Sustainable Development Goals and the wider Post-2015 Sustainable Development Agenda. While integration forms a major focus of this agenda, there are fundamental limitations on pursuing this focus. The global governance discussions on integration lack a clear conceptualization of what it is, do not have any tools for measurement or assessment, and are narrowly focused around policy integration between global institutions. This article develops a framework for conceptualizing cross-level and cross-scale integration which addresses these problems and introduces the opportunities and challenges of pursuing different types of integration in global governance. Cross-level integration involves governance efforts which seek to bridge similar institutions with one another (for example, bringing together efforts by environmental ministries and development ministries). Cross-scale integration, in contrast, deals with governance efforts that bring together institutions which have distinct scopes, jurisdictions, and epistemologies. With this important distinction, the article explores the opportunities for cross-scale integration as part of the global sustainable development efforts and particularly expanding the policy integration focus with spatial and temporal integration as well. The conclusion uses the Earth System Governance perspective to focus on the trade-offs that are likely as wider forms of institutional integration are pursued beyond environmental mainstreaming and policy integration.
