​Research findings on the relationship between climate and conflict are diverse and contested. Here we assess the current understanding of the relationship between climate and conflict, based on the structured judgments of experts from diverse disciplines. These experts agree that climate has affected organized armed conflict within countries. However, other drivers, such as low socioeconomic development and low capabilities of the state, are judged to be substantially more influential, and the mechanisms of climate–conflict linkages remain a key uncertainty. Intensifying climate change is estimated to increase future risks of conflict.

PRIO Researchers Part of New 'Nature' study

​A new study published in the journal Nature today assesses the role of climate in affecting the risk of armed conflict. Unlike conventional empirical analyses, this study is based on expert elicitation, where the data material is derived from in-depth interviews and structured group discussions among an interdisciplinary selection of scholars on climate-conflict relations. These experts agree that climate has affected organized armed conflict within countries over the past century. However, other drivers, such as low socioeconomic development, intergroup inequalities, and low state capabilities, are judged to be substantially more influential, and the mechanisms of climate–conflict linkages remain a key uncertainty. PRIO researchers Halvard Buhaug and Nina von Uexkull took part in the elicitation and co-authored the study, which was facilitated by scholars at the Woods Institute for the Environment at Stanford University.
