A Network Approach to Support Sustainability Policy Coordination: Exploring Linkages Between Biodiversity Indicators and Essential Biodiversity Variables

Abstract

Global sustainability policy demands coordination among domain-specific policies, yet a major challenge persists in policy monitoring and reporting, where various, often uncoordinated indicator initiatives exist. To address this challenge, we apply a network approach to investigate linkages between the indicators of the Sustainable Development Goal 15 (SDG 15, Life on Land), the indicators of the Aichi Biodiversity Targets and those used in assessments of the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES), and the Essential Biodiversity Variables (EBVs). Network analysis is a well-known tool but to the best of our knowledge remains largely unexplored to analyse indicator linkages. Our findings indicate limited interconnectivity (number and type of cross-set linkages) among the selected indicator sets. Nevertheless, we identify direct network linkages showing that most SDG 15 indicators could draw upon data or other information (e.g., methodological) from Aichi indicators, IPBES indicators, or EBVs. Findings show the potential of EBVs to deliver policy-relevant information, but this warrants further research. We identify indicators and EBVs with a key role in the network and discuss advantages and limitations of our network approach. We show the utility of the approach to linking multiple policy agendas, and argue that—if applied more widely—it can promote a more coordinated sustainability policy monitoring and reporting.
