A co-designed heuristic guide for investigating the peace-sustainability nexus in the context of global change.

The interlinkages between peace and sustainability are embedded in several international agreements and declarations and recognized by various research studies. However, the characteristics of their bidirectional relationship remain underexamined. Here we scope the complex and multifaceted relationship between peace and sustainability based on an experts workshop held at Hiroshima University in August 2019. The workshop focused on how peace, as a process or a condition, can help or hinder sustainability and vice versa. Relevant environmental, socio-political, and economic and technological considerations highlighted at the workshop were integrated into a co-designed heuristic guide for investigating the peace-sustainability nexus in the context of global change. The proposed guide aims to assist academic and policy researchers in identifying the specific pathways through which peace and sustainability interact when addressing complex challenges. The reinforcing potential of the two will ultimately depend on the governance and management of global transformations.
